Welcome to Matty’s (Underground) World

We flipped the switch today and dived into the world underground mining with Matty.


We break down the step by step process of mining underground, challenges different mines can face, things to keep an eye out for during ramp up, what’s underappreciated by the investing community about mining and heaps more.


Lastly, we rounded off with a rapid fire on some mining news from Evolution, St Barbara and some small cap gold bolters from the day.

1
00:00:00,080 --> 00:00:04,120
Right now, money mortars, Jesus
Christ, gold is going off it's

2
00:00:04,120 --> 00:00:07,480
head of bed.
Just it's been amazing.

3
00:00:07,560 --> 00:00:11,280
I've been on the find of brokers
and everything flat out today

4
00:00:11,280 --> 00:00:13,840
and we've finally got to the
episode now the market's closed,

5
00:00:14,160 --> 00:00:16,760
but you gotta get in early with
these gold companies.

6
00:00:16,760 --> 00:00:21,360
So mate, she's all go and we're
JC on the back of your

7
00:00:21,360 --> 00:00:26,960
sensational, unrequested from
yourself life of Valley GC in

8
00:00:26,960 --> 00:00:29,360
the world of corporate finance.
Yes.

9
00:00:29,440 --> 00:00:34,360
Why not continue this trend and
do apparently there is some

10
00:00:34,360 --> 00:00:37,040
stuff about underground mining,
et cetera that you would like to

11
00:00:37,040 --> 00:00:39,120
know?
There is no so we're gonna

12
00:00:39,240 --> 00:00:42,160
return the favour.
I'm gonna reverse Uno you and

13
00:00:43,240 --> 00:00:46,760
and I've got some questions
about underground mining, which

14
00:00:47,000 --> 00:00:50,040
you know, I've hear you're like
you've said and a few like the

15
00:00:50,040 --> 00:00:51,840
people we've had on the show to
interview.

16
00:00:51,840 --> 00:00:55,920
And and it's sort of, I kind of
get it, but then also a lot of

17
00:00:55,920 --> 00:00:58,800
it goes over my head and I
imagine a lot of other money

18
00:00:58,800 --> 00:01:02,560
miners are in the same position.
So I would love to just get back

19
00:01:02,560 --> 00:01:06,080
to basics and just to understand
actually what you used to do.

20
00:01:06,080 --> 00:01:10,240
But then some of your expertise
that can help people read

21
00:01:10,240 --> 00:01:13,400
between the lines or get in the
weeds a little bit when sort of

22
00:01:13,400 --> 00:01:15,440
reading through company
announcements, things like that

23
00:01:15,440 --> 00:01:18,160
as well.
Oh mate, in the and look, I'm

24
00:01:18,160 --> 00:01:21,120
happy to assist and in the true
honour of an underground

25
00:01:21,120 --> 00:01:25,080
episode, it's brought to you by
Quattro project engineering, the

26
00:01:25,080 --> 00:01:28,400
people that have invented most
of the shit underground, the

27
00:01:28,400 --> 00:01:32,840
mobile elevated work platform,
the the fancy ones, the the

28
00:01:32,840 --> 00:01:36,680
pasta version valves, the
friggin the fan hanging systems

29
00:01:36,680 --> 00:01:39,000
and have a look at this fly over
JC.

30
00:01:39,200 --> 00:01:41,000
They even do bloody paste
plants.

31
00:01:41,000 --> 00:01:44,400
Look at the lake cat, the lake
cow paste plant like wow,

32
00:01:44,440 --> 00:01:48,000
absolute picture of beauty and
mate, it's a holiday.

33
00:01:48,000 --> 00:01:52,080
You can go on and get paid for
it 'cause you could get paid for

34
00:01:52,080 --> 00:01:56,000
it as a Quattro employee.
So if you love building shit,

35
00:01:56,000 --> 00:01:59,240
designing shit and you're not a
Dick head and you would like to

36
00:01:59,240 --> 00:02:02,800
work for Quattro, right, Careers
at Quattro, hit them up.

37
00:02:02,800 --> 00:02:07,200
Hit them up like absolute bunch
of GCS run by Jeremy Palmer.

38
00:02:07,640 --> 00:02:10,400
Just absolute legends.
Who wouldn't want to work with

39
00:02:10,400 --> 00:02:12,960
them?
So, and we'll do a rapid fire of

40
00:02:12,960 --> 00:02:15,960
news at the end.
Bit of bloody well mate.

41
00:02:16,000 --> 00:02:18,800
I'm pumped up about gold at the
moment.

42
00:02:19,480 --> 00:02:21,640
This could be the.
Starting to sound like me.

43
00:02:21,680 --> 00:02:25,960
This could be the I think if you
take a couple of zeros off the

44
00:02:25,960 --> 00:02:29,720
market caps that you invest in,
that's where my focus is at the

45
00:02:29,880 --> 00:02:31,840
moment.
Oh, Jason.

46
00:02:31,880 --> 00:02:33,280
Oh, we'll.
Get to that.

47
00:02:33,280 --> 00:02:36,440
So we're gonna go.
Cheers to the.

48
00:02:36,440 --> 00:02:41,760
Last, the last bloody.
See Maddie, Michael, JV Oh, no,

49
00:02:41,760 --> 00:02:42,600
they're very.
Cute.

50
00:02:42,600 --> 00:02:46,720
Oh, Speaking of bloody, yeah.
Speaking of what would you say

51
00:02:46,920 --> 00:02:49,680
it's been a bit of a farming JV,
right?

52
00:02:49,680 --> 00:02:51,360
I'm just thinking of gold at the
moment, yeah.

53
00:02:52,160 --> 00:02:55,760
It's been great fun, so I've.
Had I've had a bloody belter.

54
00:02:56,120 --> 00:02:58,120
It's been cool.
Haven't been judged for anything

55
00:02:58,120 --> 00:02:59,040
I said.
It's fucking.

56
00:02:59,200 --> 00:03:03,120
Great.
Oh, so let's let's get into it.

57
00:03:03,120 --> 00:03:06,360
So we wanna go wanna go
underground with you, Maddie.

58
00:03:06,360 --> 00:03:12,320
So now you your old job, you're
now, I know you actually were a

59
00:03:12,320 --> 00:03:16,160
mining engineer to to start with
and then move to a jumbo

60
00:03:16,160 --> 00:03:20,680
operator.
I was told that my decorum would

61
00:03:20,680 --> 00:03:22,960
be more suited to the
underground environment.

62
00:03:22,960 --> 00:03:25,080
Politely.
Politely, I love it.

63
00:03:25,080 --> 00:03:27,920
Apparently dropping C bombs in
the office wasn't cool and

64
00:03:27,920 --> 00:03:30,600
punching computer screens wasn't
allowed.

65
00:03:31,240 --> 00:03:39,080
I say so a a jumbo operator, a a
jumbo, what actually is it?

66
00:03:39,400 --> 00:03:42,520
What and what is the purpose of
it in an underground?

67
00:03:42,520 --> 00:03:43,040
Mine.
Oh.

68
00:03:43,200 --> 00:03:45,960
So even after all this time,
it's still a bit confusing what

69
00:03:46,000 --> 00:03:48,440
I'm trying.
To get the oh, I, I kind of, I

70
00:03:48,440 --> 00:03:52,280
kind of understand, but just if
we go back to basics, tell us

71
00:03:52,280 --> 00:03:54,840
what is a jumbo?
What is the purpose of it in an

72
00:03:54,880 --> 00:03:55,760
underground mine?
Well.

73
00:03:55,800 --> 00:03:57,360
Why?
Why Lucky?

74
00:03:57,360 --> 00:04:01,760
There's some there's some videos
that look, mate, can't say, oh,

75
00:04:01,760 --> 00:04:03,960
I took them because you're not
allowed to take videos.

76
00:04:03,960 --> 00:04:09,880
Some of them might have, but
there's jumbo think horizontal

77
00:04:10,200 --> 00:04:13,680
then like development, you think
horizontal production, you think

78
00:04:13,680 --> 00:04:15,680
vertically.
That's the best way to explain

79
00:04:15,680 --> 00:04:17,839
it.
So like, think of this bloody

80
00:04:17,839 --> 00:04:20,720
iPad as the as the ore body just
sitting there.

81
00:04:20,720 --> 00:04:24,000
It's just this big vertical
thing that's underground and

82
00:04:24,000 --> 00:04:27,520
like you've got to the jump.
The purpose of the Jumbo is to

83
00:04:27,520 --> 00:04:31,880
develop all the drives, the
tunnels that are going

84
00:04:32,840 --> 00:04:35,560
horizontal and then you decline
it gets you deeper.

85
00:04:35,800 --> 00:04:39,040
And then when they talk
production, that's when you you

86
00:04:39,040 --> 00:04:42,720
get the rigs in to drill all the
vertical holes to, you know,

87
00:04:43,200 --> 00:04:46,000
excavate in between the tunnels
vertically.

88
00:04:46,040 --> 00:04:50,760
So that's that's so the purpose
of jumbo is development and it

89
00:04:50,760 --> 00:04:54,920
does 3 bloody does a heap of
things like the main things are

90
00:04:54,920 --> 00:04:59,680
scaling, bolting and boring.
So why not bloody take you?

91
00:04:59,760 --> 00:05:01,720
I've got a I've got a picture of
1 here.

92
00:05:01,720 --> 00:05:05,320
There's a bloody a Sandvik, one
of the new flash Sandvik jumbos,

93
00:05:05,320 --> 00:05:08,480
twin boom jumbos.
This is one picture looking out

94
00:05:08,480 --> 00:05:11,040
of the cab bloody.
There's your That's your two

95
00:05:11,040 --> 00:05:13,520
booms.
Those are the two arms.

96
00:05:13,520 --> 00:05:16,840
Yeah, and that's like that's in
an all drive at the moment, what

97
00:05:16,840 --> 00:05:20,080
you call, you know, but you
think of it as a tunnel, but

98
00:05:20,080 --> 00:05:22,240
they're called drives or
headings, OK.

99
00:05:22,600 --> 00:05:25,160
And that's the the end of it.
So and that's all your ground

100
00:05:25,160 --> 00:05:30,040
support on the they call it the
backs, the walls and the backs.

101
00:05:30,040 --> 00:05:31,800
What the top is called the
backs.

102
00:05:32,000 --> 00:05:37,080
Fun fact, it's because when the
draw, it was real small back in

103
00:05:37,080 --> 00:05:39,560
the day and you'd like crawl
through like just to fit a

104
00:05:39,560 --> 00:05:42,080
person in like your back was
touching the top.

105
00:05:42,080 --> 00:05:43,200
So that was called the back.
Oh.

106
00:05:44,160 --> 00:05:46,000
OK.
And then the front was the face

107
00:05:46,000 --> 00:05:47,640
because your face was hitting
the front.

108
00:05:48,120 --> 00:05:52,240
And then obviously then you got
your walls and down the bottom.

109
00:05:52,240 --> 00:05:55,760
So if you're standing like
you're the bottom, if you leave

110
00:05:55,760 --> 00:05:58,320
a lump on the floor, it's called
a toe because that's where your

111
00:05:58,320 --> 00:06:00,560
toes were.
There you go.

112
00:06:00,560 --> 00:06:04,160
And then the row, the row of
holes you drill just up, about

113
00:06:04,480 --> 00:06:06,680
just up above the floor were
called the knee holes.

114
00:06:06,920 --> 00:06:10,520
That's where your knees were so.
Very, very literal.

115
00:06:10,520 --> 00:06:13,800
And then and then bore the
middle outs, the guts the

116
00:06:14,200 --> 00:06:16,200
because you yeah.
So that that's all that

117
00:06:16,600 --> 00:06:19,440
terminologies like from back in
the day.

118
00:06:19,440 --> 00:06:20,720
So and.
Then so.

119
00:06:20,960 --> 00:06:22,560
Those and so the jumbo does all
that.

120
00:06:22,560 --> 00:06:27,600
So the jumbo like puts the
ground support up, bores all the

121
00:06:27,600 --> 00:06:30,000
holes in the face, which you can
see here.

122
00:06:30,000 --> 00:06:33,160
Here's a development face and
you can see all those holes that

123
00:06:33,160 --> 00:06:35,240
are put in it.
That's what the explosives go

124
00:06:35,240 --> 00:06:40,360
into to take a, you know, 3 1/2
to 4 1/2 metre chunk out, blow

125
00:06:40,360 --> 00:06:41,760
it up.
And then you gotta put the

126
00:06:41,760 --> 00:06:44,800
ground sport in and you that's
how you advance the underground.

127
00:06:45,040 --> 00:06:47,360
So I'll show you.
This like for example, like

128
00:06:47,360 --> 00:06:51,480
you'll use those booms, those
arms to put the holes into the

129
00:06:51,480 --> 00:06:53,560
face.
Well, let let me explosives go

130
00:06:53,560 --> 00:06:54,600
in there.
Mate, I haven't.

131
00:06:54,600 --> 00:06:57,040
I got some stuff for you, JC.
Let's have a look.

132
00:06:57,040 --> 00:06:59,920
Bloody.
Yeah, for as I said, they do

133
00:07:00,200 --> 00:07:01,440
scaling.
That's one thing.

134
00:07:01,440 --> 00:07:05,000
This is the argument between
bloody North America and

135
00:07:05,000 --> 00:07:06,920
Australia.
Well, they have bolting rigs and

136
00:07:06,920 --> 00:07:09,760
then scaling rigs.
And whereas in Australia the

137
00:07:09,760 --> 00:07:12,640
whole thing about a jumbo, here
you have a jumbo that can do

138
00:07:12,640 --> 00:07:15,880
everything and an and an
operator that can do everything.

139
00:07:15,880 --> 00:07:20,040
So this is an example of a jumbo
scaling, so you can see it

140
00:07:21,480 --> 00:07:26,160
bloody just pretty much drilling
holes into the newly excavated

141
00:07:26,160 --> 00:07:27,840
rock to drop all the loose shit
off.

142
00:07:27,840 --> 00:07:29,880
So that's like how you get all
'cause that loose stuff will

143
00:07:29,880 --> 00:07:32,800
fall on someone's head otherwise
or it'll bag up behind the mesh.

144
00:07:32,800 --> 00:07:36,320
So you tap it and with the
drill, with all the percussion

145
00:07:36,360 --> 00:07:37,600
and force behind.
It.

146
00:07:37,760 --> 00:07:39,560
And that's it.
And that's how you, and then

147
00:07:39,560 --> 00:07:42,840
that's you use that to actually
scale the face in front of you

148
00:07:42,840 --> 00:07:45,400
to get all the loose shit off
before you bore the holes in it

149
00:07:45,520 --> 00:07:47,440
so it doesn't all fall on the
frigging ground.

150
00:07:47,440 --> 00:07:50,520
So you scale, then you put
ground support, and then you you

151
00:07:50,520 --> 00:07:52,960
start to bore holes.
So here's an example of the OK,

152
00:07:53,320 --> 00:07:57,400
putting the ground support up.
So that's, you know, you use one

153
00:07:57,400 --> 00:08:00,840
boom to lift the mesh up and
then you jam it in and you

154
00:08:00,840 --> 00:08:06,000
rotate it into position and then
you use the other boom to, you

155
00:08:06,000 --> 00:08:09,520
know, start drilling a hole.
And so it's all like a big time

156
00:08:09,520 --> 00:08:11,840
in motion exercise.
So you know, when you're

157
00:08:11,840 --> 00:08:14,280
learning it, it's the freaking
hardest thing in the world.

158
00:08:15,320 --> 00:08:18,000
And then, you know, you start
getting all right at it, but

159
00:08:18,000 --> 00:08:20,840
then after, you know, 6 to 10
years, you start really

160
00:08:21,160 --> 00:08:23,880
perfecting the perfecting the
art of it.

161
00:08:23,880 --> 00:08:27,360
And that's why, you know, these
people get bloody paid so much

162
00:08:27,360 --> 00:08:29,800
to do it 'cause once you get
really good at it, which is.

163
00:08:29,800 --> 00:08:30,640
Just move.
Quickly.

164
00:08:30,640 --> 00:08:33,919
Well like it's like once I had
six years on it so it took me 5

165
00:08:33,919 --> 00:08:37,480
years to figure out bloody slow
down and stop on trying to be a

166
00:08:37,480 --> 00:08:40,760
bloody cowboy and a hero.
So I had a good last year you'd

167
00:08:40,760 --> 00:08:43,400
say I was friggin pain in the
ass for the 1st 5 on it.

168
00:08:44,280 --> 00:08:47,920
But then like if I if I stayed
on it from that point I would

169
00:08:47,920 --> 00:08:52,000
have started refining everything
and got like shaving seconds off

170
00:08:52,000 --> 00:08:54,920
every process and start really
getting a lot.

171
00:08:54,920 --> 00:08:57,800
Getting your straps, Yeah.
Really getting a lot done with

172
00:08:58,080 --> 00:09:01,640
like what the real experienced
and switched on followers do.

173
00:09:01,640 --> 00:09:04,920
I didn't really get to that get
to that level as much as I

174
00:09:04,920 --> 00:09:06,320
probably thought I did at the
time.

175
00:09:07,000 --> 00:09:09,080
So that's the that's the bolting
side.

176
00:09:09,080 --> 00:09:13,840
And then then if you look at the
the boring side.

177
00:09:13,840 --> 00:09:15,760
So this is a speed up version or
found.

178
00:09:16,800 --> 00:09:19,520
So that's both booms.
Just drill and holes into the

179
00:09:19,520 --> 00:09:23,800
face in a pattern to to blast it
out effectively.

180
00:09:23,800 --> 00:09:26,720
And you'll like drills the
perimeter, which drills the

181
00:09:26,720 --> 00:09:28,800
shape of it.
And you've got to have your boom

182
00:09:29,080 --> 00:09:32,040
angled correctly and going in
the right direction to match

183
00:09:32,040 --> 00:09:35,840
what the actual survey direction
of the drive is and the height

184
00:09:35,840 --> 00:09:38,160
and the width.
And then at the end there you'll

185
00:09:38,160 --> 00:09:40,680
see them drill like it's called
a burn.

186
00:09:40,800 --> 00:09:43,680
They'll drill a closed in
pattern and put these rimas in

187
00:09:43,680 --> 00:09:47,080
with which are the initial void.
And then so chart the shop fires

188
00:09:47,080 --> 00:09:53,720
come in, fill it with explosives
and bloody sequence it so it

189
00:09:53,720 --> 00:09:57,480
starts from the middle and fires
into the void and then makes the

190
00:09:57,480 --> 00:10:00,520
void bigger and keeps going till
you've excavated this whole

191
00:10:00,560 --> 00:10:03,880
thing.
So it's the technical side of it

192
00:10:03,880 --> 00:10:10,000
is trying to get the angles
right and trying to, you know,

193
00:10:10,040 --> 00:10:12,080
keep everything neat and tidy
and and flowing.

194
00:10:12,080 --> 00:10:14,360
But then you if you have
multiple jumbos, you got

195
00:10:14,360 --> 00:10:18,160
multiple operators with
different experience levels and

196
00:10:18,600 --> 00:10:22,120
the jumbo is the first is the
thing that the whole mine

197
00:10:22,120 --> 00:10:26,400
development follows and 'cause.
You're literally at the

198
00:10:26,400 --> 00:10:28,600
coalface.
Cause the jump, you're the

199
00:10:28,600 --> 00:10:32,080
jumbo's doing all that until
that Jumbo's finished boring the

200
00:10:32,080 --> 00:10:34,400
holes charge up.
Can't get in there to charge it

201
00:10:35,280 --> 00:10:37,000
until that.
Is when you say charging.

202
00:10:37,360 --> 00:10:39,280
Shot fire, Explosives.
Explosives.

203
00:10:39,280 --> 00:10:42,320
Yeah, yeah.
And it's and, and until the till

204
00:10:42,320 --> 00:10:46,040
the it's been blasted the bogger
like the bloody thing with the

205
00:10:46,040 --> 00:10:48,960
bucket on the front that can't
bog the dirt.

206
00:10:49,320 --> 00:10:52,560
So and yeah.
And so then the jumbo can't get

207
00:10:52,560 --> 00:10:54,680
back in till the spot till the
bog is finished.

208
00:10:54,680 --> 00:10:58,640
And like the whole and it's all
that's how when we talk about,

209
00:10:59,520 --> 00:11:03,360
you know, trying to Bellevue and
Kathleen Valley and that trying

210
00:11:03,360 --> 00:11:06,240
to target 300 odd metres per
month per jumbo.

211
00:11:06,640 --> 00:11:10,360
That number is dictated on how
efficient that operator is on

212
00:11:10,360 --> 00:11:14,600
the jumbo and every piece of
machinery in person around them

213
00:11:14,800 --> 00:11:20,280
trying to work for a 12 hour
shift twice a day everyday and

214
00:11:20,280 --> 00:11:23,560
all the management behind it to
keep that whole process flowing

215
00:11:23,880 --> 00:11:26,440
month on month to try and
achieve those metrics.

216
00:11:26,440 --> 00:11:31,760
So it's like we look at a number
on a quarterly at what it is

217
00:11:32,480 --> 00:11:36,760
just like it's a simple number.
But what goes into making that

218
00:11:36,760 --> 00:11:40,360
happen like the service crew
that provide all the the

219
00:11:40,360 --> 00:11:44,520
ventilation and the water to
keep the jumbo going, the the

220
00:11:44,520 --> 00:11:48,880
sparkies that have to provide
the power to the jumbo and keep

221
00:11:48,880 --> 00:11:51,160
extending because as the mine
grows, like you have to keep

222
00:11:51,160 --> 00:11:55,640
extending it and like the pumps.
Are jumbo powered. 1000 Volt

223
00:11:55,640 --> 00:11:59,160
electricity.
So you drive it around on diesel

224
00:11:59,440 --> 00:12:02,880
and then all the power that's on
the surface like whether it's

225
00:12:03,160 --> 00:12:07,880
usually diesel generators or gas
fired bloody power station with

226
00:12:07,920 --> 00:12:14,400
renewable backup, like all that
is fed via 11 KV bloody

227
00:12:14,400 --> 00:12:19,000
electrical cables underground
and then distributed into drop

228
00:12:19,000 --> 00:12:21,800
down to goes into like
substations which drop it down

229
00:12:21,800 --> 00:12:24,680
to the 1000 Volt.
And then that 1000 Volt power is

230
00:12:25,600 --> 00:12:28,840
in like orange cables
distributed all through the mine

231
00:12:29,280 --> 00:12:31,560
to a jumbo box.
And then you'll have an extent

232
00:12:31,560 --> 00:12:34,000
could have an extension cable
coming out and that's what the

233
00:12:34,000 --> 00:12:37,840
jumbo plugs into.
It's called the Macy plug and

234
00:12:37,840 --> 00:12:41,280
that that is how so yeah.
So we're powered on 240 Volt in

235
00:12:41,320 --> 00:12:43,520
this office.
Jumbos are powered on one,

236
00:12:43,680 --> 00:12:46,160
everything underground is
powered on 1000 volts.

237
00:12:46,600 --> 00:12:49,480
Wow.
So that's and he might then they

238
00:12:49,480 --> 00:12:54,560
can do like like cable bolts,
for instance, like you can use a

239
00:12:54,560 --> 00:13:00,040
jumbo to normally it only drills
a you know, a three 2 1/2 meter

240
00:13:00,040 --> 00:13:05,680
hole or whatever for your or
2.8m hole for your bolting when

241
00:13:05,680 --> 00:13:07,760
you're bolting.
Or you can open it up to drill a

242
00:13:08,280 --> 00:13:10,960
four and a half metre hole for
boring.

243
00:13:11,320 --> 00:13:15,920
You have the longer jumbos like
they can drill 6 metre holes in

244
00:13:15,920 --> 00:13:17,680
one go.
Like yeah, right, fix boring

245
00:13:17,680 --> 00:13:19,120
things.
But you can actually like drill

246
00:13:19,120 --> 00:13:22,800
cable bolt holes with them, like
use them as a production rig and

247
00:13:22,800 --> 00:13:25,360
I'll show you, I'll show you.
Bloody is a bloody cool.

248
00:13:26,240 --> 00:13:30,440
Whoever whoever doing was doing
this was a bloody bit of a Mad

249
00:13:30,440 --> 00:13:34,520
Dog.
Don't know it was, but like you

250
00:13:34,520 --> 00:13:40,840
can actually, you can actually,
you know, drill 6m holes, like

251
00:13:41,640 --> 00:13:45,640
3M hole twice with a jumbo and
attach a second rod onto it.

252
00:13:45,640 --> 00:13:47,920
And that's how they drill the
intersection cables.

253
00:13:47,920 --> 00:13:50,680
So it's like a 6m hole.
And this one here they're

254
00:13:50,680 --> 00:13:55,720
actually using the one boom to
drill through the other boom and

255
00:13:55,720 --> 00:13:58,280
then like swapping the rod.
So you'll see it here, the pace

256
00:13:58,280 --> 00:14:02,080
it normally goes, I've speed it
up just to shout and then you

257
00:14:02,080 --> 00:14:04,360
can, yeah.
So they're like, you can do so

258
00:14:04,360 --> 00:14:08,600
many funky things with them.
And yeah.

259
00:14:08,600 --> 00:14:13,280
They're quite multi purposes.
You sort of got one bit of kit,

260
00:14:13,280 --> 00:14:16,120
or what would you call it, kit
or is it a machine?

261
00:14:16,160 --> 00:14:18,120
No, it's just a big bloody yeah,
it's a machine.

262
00:14:18,280 --> 00:14:19,680
It is a.
That does.

263
00:14:19,680 --> 00:14:21,560
Machine worth a couple
$1,000,000.

264
00:14:21,920 --> 00:14:25,640
Yeah, just just essentially does
the development side of it.

265
00:14:25,680 --> 00:14:29,920
But then, like you say, you've
got other service providers and,

266
00:14:29,920 --> 00:14:33,760
and machines and kit sort of OK,
you do this place and the next

267
00:14:33,760 --> 00:14:37,160
person's got to go and then the
following person comes after

268
00:14:37,160 --> 00:14:38,840
then and then it cycles again
and again.

269
00:14:38,840 --> 00:14:41,800
But just to have that, that
rhythm and everything to be

270
00:14:41,800 --> 00:14:44,520
going right and on time and all
that.

271
00:14:44,520 --> 00:14:49,480
It's, there's a lot of, I guess
probably what I didn't

272
00:14:49,480 --> 00:14:52,800
appreciate is how many it's not
just say you and a jumbo going

273
00:14:52,840 --> 00:14:54,400
boom, boom, and then it's all
good.

274
00:14:54,400 --> 00:14:56,920
Like there's so many variables
that all have to be going right

275
00:14:56,920 --> 00:15:00,000
and all at the correct time to
keep that flow.

276
00:15:00,840 --> 00:15:03,400
Going well you need you need the
jumbo to do all that you need

277
00:15:03,400 --> 00:15:06,160
the bogger to bog the dirt.
You need the chart shop fires to

278
00:15:06,160 --> 00:15:08,320
blow it up.
You need the bogger to bog the

279
00:15:08,320 --> 00:15:10,080
dirt out.
You need the bogger to put the

280
00:15:10,120 --> 00:15:13,040
dirt into a truck.
So the truck takes that to the

281
00:15:13,040 --> 00:15:17,440
surface and then you need a
service crew that is sorting out

282
00:15:17,440 --> 00:15:20,680
your water, your power, your
ventilation infrastructure keep

283
00:15:20,800 --> 00:15:23,480
that all going and that is just
for development.

284
00:15:23,800 --> 00:15:26,400
That is that doesn't say when I
talk about production, I

285
00:15:26,400 --> 00:15:31,320
actually found be rude not to
show a Sambic production rig.

286
00:15:31,320 --> 00:15:34,920
This was a public video, but
that's what a that's a

287
00:15:34,920 --> 00:15:37,800
production rig.
So it's like, think of a jumbo,

288
00:15:37,800 --> 00:15:41,360
but it's all drilling big, long,
longer holes, fatter and they're

289
00:15:41,360 --> 00:15:45,560
all vertical and sideways and
they're the holes that are used

290
00:15:46,120 --> 00:15:51,400
to take that all the ore out
between the levels, which are

291
00:15:51,400 --> 00:15:54,880
like, you know, the levels, the
jumbo levels could be, you know,

292
00:15:54,880 --> 00:15:59,440
20 metres apart or 25 or 15.
These rigs come in all shapes

293
00:15:59,440 --> 00:16:03,880
and sizes and they drill the
pattern out to excavate the ore.

294
00:16:03,880 --> 00:16:06,840
So all this development and
decline and infrastructure and

295
00:16:06,840 --> 00:16:11,040
all that, that is all there for
the purpose to potentially take

296
00:16:11,040 --> 00:16:15,360
out just this frigging gold vine
and or hopefully there's

297
00:16:15,360 --> 00:16:17,080
multiple Gulf veins on one
level.

298
00:16:17,480 --> 00:16:20,120
And so that is the difference
between development and

299
00:16:20,120 --> 00:16:23,960
production.
So then so say you've developed

300
00:16:24,040 --> 00:16:27,000
a level of the like a, like a
tunnel basically.

301
00:16:27,000 --> 00:16:30,320
So you've developed, you know,
one here, 1 below it.

302
00:16:30,400 --> 00:16:34,560
And then once you've finished
the development with a with a

303
00:16:34,560 --> 00:16:39,000
Jumbo, then this production rig
comes in and starts going

304
00:16:39,240 --> 00:16:42,400
vertically to excavate the the
ore.

305
00:16:42,400 --> 00:16:45,960
Yeah, it no, it just, it just
drills holes vertically and then

306
00:16:46,000 --> 00:16:49,240
the shop fires fill them up with
explosives as well.

307
00:16:49,600 --> 00:16:51,800
And that's how they blast out
the production.

308
00:16:52,200 --> 00:16:55,920
But like for a level, you know,
you'll you'll come in, there'll

309
00:16:55,920 --> 00:16:58,680
be the access to get in there.
Then there'll be a stockpile to

310
00:16:58,680 --> 00:17:01,480
put all the dirt.
Then you need an escape way.

311
00:17:01,480 --> 00:17:03,720
So you've got egress out to go
up and down.

312
00:17:03,720 --> 00:17:07,560
If there's a fire, then you've
got could be a refuge chamber

313
00:17:07,560 --> 00:17:13,000
Cuddy, then you've got could be
some area for power or and then

314
00:17:13,000 --> 00:17:16,319
you then you actually get into
the the jump light level.

315
00:17:16,319 --> 00:17:19,319
So when you talk about a level,
there's a lot of little, you

316
00:17:19,319 --> 00:17:23,280
know, cuddies everywhere for
that serve a purpose for each

317
00:17:23,280 --> 00:17:26,359
part of that cycle because you
can't get the dirt out if you

318
00:17:26,359 --> 00:17:28,880
don't have a stock ball to put a
dirt, put the dirt.

319
00:17:29,120 --> 00:17:34,440
You can't load the truck if you
haven't lifted the height of the

320
00:17:34,440 --> 00:17:37,360
backs for the bogger to lift the
bucket up to tip the dirt into

321
00:17:37,360 --> 00:17:38,880
the truck.
Like there's all and that's,

322
00:17:39,080 --> 00:17:42,280
that's what engineers do.
And to design it all.

323
00:17:42,280 --> 00:17:46,400
And usually the then the
foreman's and everything, you'll

324
00:17:46,400 --> 00:17:48,360
yell at the engineers.
They're like, you didn't fucking

325
00:17:48,360 --> 00:17:50,960
do this right.
You bloody engineers don't know

326
00:17:50,960 --> 00:17:53,240
how to fucking mind 'cause it's,
yeah.

327
00:17:53,240 --> 00:17:56,720
So it's, oh, it's such good.
So many good personalities up

328
00:17:56,720 --> 00:17:58,120
there.
Friggin love it.

329
00:17:58,360 --> 00:18:03,440
And then so, and this is the
sort of imagine development and

330
00:18:03,440 --> 00:18:06,440
stopping ore.
So development ore ore sort of

331
00:18:06,440 --> 00:18:09,520
refers to the rock that's
getting taken out when the

332
00:18:09,520 --> 00:18:14,440
jumbo's going through and the
stopping ore is sort of post the

333
00:18:14,440 --> 00:18:17,440
production rig and the
explosives going in up

334
00:18:17,440 --> 00:18:20,720
vertically that all that drops
out is stopping ore.

335
00:18:20,720 --> 00:18:25,440
Yeah, well, you think of say
there's levels 2020 metres

336
00:18:25,440 --> 00:18:29,200
apart.
And so the the development ore

337
00:18:29,200 --> 00:18:32,280
is just when, yeah, the jumbo
excavates the tunnel through the

338
00:18:32,280 --> 00:18:35,080
ore because you can't, the
production rig can't get in

339
00:18:35,080 --> 00:18:37,680
there to drill the holes through
the ore body without the jumbo

340
00:18:37,680 --> 00:18:39,200
creating the tunnel for it.
To get in.

341
00:18:39,440 --> 00:18:43,640
There, So yeah, development ore
you're taking out, you know, 5

342
00:18:43,640 --> 00:18:48,880
metres worth and then there's 20
metres of or above it till the

343
00:18:48,880 --> 00:18:52,640
next level.
So it takes a lot longer to

344
00:18:52,880 --> 00:18:56,920
develop that the five meter
chunk, whereas when you blow the

345
00:18:56,920 --> 00:18:59,480
whole thing up, you've just got
a shit load of dirt to bog.

346
00:18:59,880 --> 00:19:04,320
So that's what they talk about
and and that you can excavate it

347
00:19:04,320 --> 00:19:06,680
skinnier because you don't have
to put ground sport, no one's

348
00:19:06,680 --> 00:19:08,240
allowed up in there like you
can't.

349
00:19:08,400 --> 00:19:09,600
Just gravity, right?
All the.

350
00:19:09,640 --> 00:19:11,240
Rocks.
Well, no, you can't like you

351
00:19:11,400 --> 00:19:16,480
Yeah, well you don't the jump.
These are 5 meters wide to for a

352
00:19:16,480 --> 00:19:19,720
purpose like you've got a
because you're restricted by or

353
00:19:19,720 --> 00:19:22,240
foot they 4 1/2.
You can get 2 with these twin

354
00:19:22,240 --> 00:19:24,880
boom jumbos.
You can't get them really much

355
00:19:24,880 --> 00:19:28,800
smaller because you can't fit
the jumbo booms in there and you

356
00:19:29,000 --> 00:19:30,080
and everything.
So.

357
00:19:30,080 --> 00:19:33,480
But when you mine a narrow vine,
like they could mine in it like

358
00:19:33,640 --> 00:19:36,960
2 1/2 meters wide.
So your development ore is 5

359
00:19:36,960 --> 00:19:38,400
meters wide.
But if you got gold in the

360
00:19:38,400 --> 00:19:41,080
middle, that means you got all
that waste on the outside.

361
00:19:41,520 --> 00:19:44,160
So.
Whereas when you mine it 2 1/2

362
00:19:44,160 --> 00:19:47,360
meters wide and hopefully just
get the vine, that means you

363
00:19:47,880 --> 00:19:50,520
your grade of that is a lot
higher.

364
00:19:50,520 --> 00:19:53,040
So you're stopping ore is higher
grade because you haven't taken

365
00:19:53,040 --> 00:19:56,560
out as much width.
That's this is for narrow van

366
00:19:56,560 --> 00:20:00,920
gold mining, but so that but and
you get a lot more of it.

367
00:20:00,920 --> 00:20:04,840
So that's why they talk about
you want you don't want to be

368
00:20:04,840 --> 00:20:07,440
just tracking all the
development or up and not

369
00:20:07,440 --> 00:20:09,920
focusing on the stopping or
because the stopping or there's

370
00:20:09,920 --> 00:20:12,040
more of it and it's higher
grade.

371
00:20:12,720 --> 00:20:14,560
So.
Because you're targeting it.

372
00:20:14,560 --> 00:20:18,440
Well, it's more targeted I
guess, because you're aiming for

373
00:20:19,480 --> 00:20:21,640
the the ore that.
Oh, that, but the jumbo

374
00:20:21,640 --> 00:20:23,080
development goes straight
through the ore.

375
00:20:23,080 --> 00:20:26,760
MMM 'cause that's where that
gives you the The jumbo

376
00:20:26,760 --> 00:20:28,680
development is purely for
access.

377
00:20:28,680 --> 00:20:32,920
Yeah, for the machinery to the
end goal is taking that stop

378
00:20:32,920 --> 00:20:33,600
out.
Stop out.

379
00:20:33,600 --> 00:20:36,200
That is, everything that goes on
is purely for that goal.

380
00:20:36,480 --> 00:20:40,320
That's what some places you
forget, 'cause the jumbo's or

381
00:20:40,320 --> 00:20:43,480
the might have been incentivized
by doing more development

382
00:20:43,480 --> 00:20:47,040
because I get paid more for it.
And the focus, there was always,

383
00:20:47,120 --> 00:20:50,000
always that culture of like you
can't stop the jumbo.

384
00:20:50,680 --> 00:20:54,720
But if the focus goes off
production too much, yeah, the

385
00:20:54,720 --> 00:20:57,400
primary purpose is getting the
production or out to feed the

386
00:20:57,400 --> 00:21:01,960
mill to all gold or float copper
or so you could actually make

387
00:21:01,960 --> 00:21:03,400
money.
OK.

388
00:21:03,480 --> 00:21:06,880
Because that was something I
was, I kind of understood.

389
00:21:06,880 --> 00:21:10,360
But now that makes a lot more
sense.

390
00:21:10,360 --> 00:21:11,800
And why?
Yeah, you often say, yeah,

391
00:21:11,800 --> 00:21:15,920
you're stopping all higher than
your or ideally higher than your

392
00:21:15,920 --> 00:21:18,040
development.
All should be unless it the

393
00:21:18,040 --> 00:21:20,920
hanging wall falls in and
dilutes it and you've got a heap

394
00:21:20,920 --> 00:21:23,440
of waste mixed in it and you've
got to bog it out anyway.

395
00:21:23,680 --> 00:21:27,640
Yeah, that's and that we can
talk about later the dip and

396
00:21:27,640 --> 00:21:29,920
foot wall and angles and
recovery and.

397
00:21:30,160 --> 00:21:32,640
All that, all that.
You just bloody ask me whatever

398
00:21:32,640 --> 00:21:34,120
you want to say.
No.

399
00:21:34,120 --> 00:21:39,440
So sort of moving on from that a
little bit, how do you look at

400
00:21:39,480 --> 00:21:44,880
an ore body and the mind design
and trying to see if you can,

401
00:21:44,960 --> 00:21:47,880
you know, hit all the targets or
not?

402
00:21:48,360 --> 00:21:51,400
Yeah.
So you got to think of how much

403
00:21:51,760 --> 00:21:54,440
when they talk about a 1,000,000
tonne per annum operation,

404
00:21:54,440 --> 00:22:00,880
that's 1,000,000 tonne of ore.
So if you've got add to grosser

405
00:22:00,880 --> 00:22:05,320
for instance, that was, you know
big, it's like AVMS deposit.

406
00:22:05,320 --> 00:22:09,920
So it was like a big, big chunk
of copper and it was like, you

407
00:22:09,920 --> 00:22:12,800
know, 2030 meters thick.
And on one level it would be,

408
00:22:13,000 --> 00:22:17,520
you know, 100 and oh, it was 100
odd hundred 200 meters long.

409
00:22:18,160 --> 00:22:21,720
So you you've got these.
So a stoke there is like 20 by

410
00:22:21,720 --> 00:22:24,480
20 at the bottom.
And you know, it could be 50 or

411
00:22:24,480 --> 00:22:27,200
60 meters high.
Like it's a big thick chunk of

412
00:22:27,200 --> 00:22:29,960
ore.
And so you can, there's hyper

413
00:22:29,960 --> 00:22:33,920
dirt to bog and yeah, you know,
you can spend a month or so

414
00:22:34,080 --> 00:22:36,640
bogging it till you finish.
And a stoke might be 100 odd,

415
00:22:36,640 --> 00:22:39,080
1000 tons.
Whereas you go to a narrow vein

416
00:22:39,080 --> 00:22:43,880
gold mine, you've got, there's
one vein and you're like might,

417
00:22:44,080 --> 00:22:47,440
you know, stoke might be 5000
ton or 10,000 ton.

418
00:22:47,440 --> 00:22:50,600
So because you're doing these
narrow veins, so you think of

419
00:22:50,600 --> 00:22:54,680
how many Stokes you've got a
mine that are 510 thousand ton

420
00:22:54,920 --> 00:22:58,040
to get 1,000,000 tonne.
And every time you finish a

421
00:22:58,040 --> 00:23:00,800
stoke, you've got to either
leave a pillar or backfill it

422
00:23:00,800 --> 00:23:03,880
and then drill the next one and
like that cycle continues.

423
00:23:03,880 --> 00:23:06,880
So you've to get a.
Pillar A pillar is.

424
00:23:06,920 --> 00:23:10,000
Oh, so it's like, say in that
you can't just take the whole

425
00:23:10,000 --> 00:23:13,720
chunk of ore out because it'll
just, it'll just fall in because

426
00:23:13,720 --> 00:23:17,160
it's like too much of A
hydraulic radius exposure and

427
00:23:17,160 --> 00:23:21,160
it'll just start caving in and
likely.

428
00:23:21,440 --> 00:23:24,400
And then it'll dilute your ore
and could just keep flowing

429
00:23:24,400 --> 00:23:26,720
down.
Like as soon as you open up the

430
00:23:26,720 --> 00:23:29,840
levels below it, the Stokes
below it, all that dirt falls

431
00:23:29,840 --> 00:23:32,520
down.
And you, you know, yeah, your 6g

432
00:23:32,520 --> 00:23:35,240
dirt rapidly becomes 4G.
Yeah.

433
00:23:36,320 --> 00:23:42,480
So that, so you leave, you might
mind 203040 meters, like 40

434
00:23:42,480 --> 00:23:44,480
meters.
If it's good ground then you'll

435
00:23:44,480 --> 00:23:46,000
stop.
You'll leave a chunk of rock

436
00:23:46,200 --> 00:23:48,800
which is ore.
It's called a pillar, and then

437
00:23:48,800 --> 00:23:51,760
you restart the process so that
pillar supports.

438
00:23:51,760 --> 00:23:55,720
It's your support.
Supports the hanging wall and

439
00:23:56,160 --> 00:24:00,160
hopefully stops it from falling
in the more you expose it.

440
00:24:00,320 --> 00:24:02,720
And the hanging wall is
basically what's above you.

441
00:24:03,160 --> 00:24:05,240
Hanging.
So you think of a vertical, dead

442
00:24:05,240 --> 00:24:08,240
vertical start.
There isn't really a hanging

443
00:24:08,240 --> 00:24:12,120
wall because it's all vertical.
If it rolls over that way, if

444
00:24:12,120 --> 00:24:15,240
it's dipping at 80°, that's your
hanging wall, That's your foot

445
00:24:15,240 --> 00:24:18,040
wall.
And then so all bodies do that.

446
00:24:18,120 --> 00:24:19,520
Yeah.
Are they either they're either

447
00:24:19,520 --> 00:24:23,400
vertical or bloody dead flat.
Yeah, they're not like a coal

448
00:24:23,400 --> 00:24:26,880
seams dead flat, but they're
usually mixtures between, you

449
00:24:26,880 --> 00:24:30,840
know, 20-30 degrees all.
The way up to. 90° So when they

450
00:24:30,840 --> 00:24:34,640
call it sub vertical, it means
it's pretty bloody close to

451
00:24:34,640 --> 00:24:38,640
vertical.
So what's some examples?

452
00:24:38,720 --> 00:24:42,880
I think oh, like Daisy Milano
when I was there, perfectly

453
00:24:42,880 --> 00:24:45,720
vertical, most of it, a lot of
it was pretty much dead

454
00:24:45,720 --> 00:24:47,560
vertical.
I think Aurabanda looks pretty

455
00:24:47,560 --> 00:24:51,320
vertical.
You know, Bellevue looks like it

456
00:24:51,320 --> 00:24:52,720
varies.
It's somewhere close to

457
00:24:52,720 --> 00:24:55,840
vertical.
Then they lay over a bit like

458
00:24:55,840 --> 00:24:59,360
Spartan looks to be about 60-70
degrees.

459
00:24:59,600 --> 00:25:03,440
So whereas and then you go to
Gualia, places like, you know,

460
00:25:03,440 --> 00:25:06,640
around that Leonora area, Gualia
that dips at 40°.

461
00:25:06,760 --> 00:25:12,600
So it's really laid over.
So the issues should come into

462
00:25:12,600 --> 00:25:18,080
there is dead vertical in hard
ground ideal.

463
00:25:18,200 --> 00:25:22,600
So you can't really have nothing
will hopefully naturally fall in

464
00:25:23,080 --> 00:25:26,880
because it's vertical.
But you can't have air mines

465
00:25:26,880 --> 00:25:31,240
that are dead vertical with real
laminated laminated ground that

466
00:25:31,240 --> 00:25:35,520
can sort of peel in and dilute
which is I think there's a

467
00:25:35,520 --> 00:25:38,560
restart project coming up that
has that sort of ground

468
00:25:38,560 --> 00:25:40,600
historically.
I'm not like if it's sure that

469
00:25:40,800 --> 00:25:46,280
if it's like that going forward,
but then if it then if it's

470
00:25:46,280 --> 00:25:49,480
lying over at 60° and you got
poor ground, like you might want

471
00:25:49,480 --> 00:25:51,800
to just take out this chunk
here.

472
00:25:52,360 --> 00:25:56,680
But then that starts falling in.
So that just starts blowing out

473
00:25:56,680 --> 00:26:00,600
and that's all waste.
And that, as I said, takes you

474
00:26:01,120 --> 00:26:03,600
like you can only put a fixed
amount of ore through the mill

475
00:26:03,600 --> 00:26:05,640
each year.
So say you've got 1,000,000

476
00:26:05,640 --> 00:26:08,960
tonne to go through and all that
shit's fallen in, all that

477
00:26:08,960 --> 00:26:09,680
shit's got to go.
Through.

478
00:26:09,680 --> 00:26:12,920
It's got to go through.
So 1,000,000 at right 4G

479
00:26:13,400 --> 00:26:15,240
compared to 1,000,000 at 3
grams.

480
00:26:15,240 --> 00:26:20,000
That's a shit load of answers
that you've lost due to a lower

481
00:26:20,000 --> 00:26:21,920
head grade.
So that's why.

482
00:26:22,280 --> 00:26:26,160
And then when it lies over more
you obviously have the risk of

483
00:26:26,800 --> 00:26:31,480
the hanging wall caving in so
you got to try and protect it.

484
00:26:32,400 --> 00:26:36,400
Can't expose it too much, but
then you've got the foot wall as

485
00:26:36,400 --> 00:26:39,040
well.
So the shallower it is the if

486
00:26:39,040 --> 00:26:42,400
you fire too much dirt or just
it doesn't roll down the foot

487
00:26:42,400 --> 00:26:44,160
wall into the draw point to bog
it out.

488
00:26:44,160 --> 00:26:46,000
It just sits there.
So you either got to wash it

489
00:26:46,000 --> 00:26:48,320
down or you've you've got to
fire a.

490
00:26:48,320 --> 00:26:50,600
Little, but he's not helping.
You, no, you got to, you got to

491
00:26:50,600 --> 00:26:53,480
fire just little bits at a time.
So it just sort of drops enough

492
00:26:53,480 --> 00:26:56,640
into the drive so you can bog it
out and doesn't sit on the foot

493
00:26:56,640 --> 00:26:59,960
wall.
And so yeah, if it's too flat,

494
00:26:59,960 --> 00:27:05,320
like if it's below 6055° it just
doesn't run down, then you might

495
00:27:05,320 --> 00:27:10,080
have to actually take a chunk
out of the foot wall of waste to

496
00:27:10,200 --> 00:27:11,880
steepen it up so it actually
rules.

497
00:27:11,880 --> 00:27:15,720
Which again dilutes you because
you're having to take waste

498
00:27:15,720 --> 00:27:16,920
you're.
Taking waste, yeah.

499
00:27:17,800 --> 00:27:20,720
With with the the ore that
you're trying to get out.

500
00:27:20,720 --> 00:27:22,560
Yeah.
And I think and I think I would

501
00:27:22,560 --> 00:27:24,920
assume and it's rinse and
repeat.

502
00:27:24,920 --> 00:27:28,680
So Gualia, it has been like that
for ages.

503
00:27:29,000 --> 00:27:30,640
It's just how it is.
It's just how it is.

504
00:27:30,640 --> 00:27:34,920
So I would assume like looking
at their grade and everything

505
00:27:34,920 --> 00:27:39,560
like they, they would know the
process over and over again to

506
00:27:39,560 --> 00:27:42,720
ensure that they get the foot
wall dirt out.

507
00:27:42,720 --> 00:27:45,400
They control the dilution on the
hanging wall.

508
00:27:45,400 --> 00:27:47,080
It probably doesn't always go
right.

509
00:27:47,080 --> 00:27:48,640
Like there's always something
that fucks up.

510
00:27:49,080 --> 00:27:53,600
Sometimes a person that might
fuck up and like overcharge it

511
00:27:53,600 --> 00:27:55,840
or drill it incorrectly or
something like that.

512
00:27:55,840 --> 00:28:00,000
There's a lot of there's so many
things to control underground.

513
00:28:00,000 --> 00:28:02,360
So, so a lot of things are out
of your control, but there's so

514
00:28:02,360 --> 00:28:05,720
many things to control as well
from management like keeping

515
00:28:05,720 --> 00:28:10,200
their eye on, you know, drilling
accuracy, like trying to not

516
00:28:11,200 --> 00:28:16,680
drill too fast and try and be a
hero and actually deviating or

517
00:28:16,680 --> 00:28:20,480
like missing the OR like it's
all, it all looks good on paper.

518
00:28:20,480 --> 00:28:28,160
But like, that's, and that's why
some mines might be, you know,

519
00:28:28,160 --> 00:28:32,320
have a reserve of 6 grams and
their head grades coming out at

520
00:28:32,360 --> 00:28:34,840
4 four and a half.
They're like, well, what's

521
00:28:34,840 --> 00:28:37,840
wrong?
Like why what's is, is the

522
00:28:37,840 --> 00:28:41,280
drilling incorrect?
Like there was some people like

523
00:28:41,320 --> 00:28:44,320
think, oh, well, they must have
bloody overcalled the resource.

524
00:28:44,320 --> 00:28:49,000
I'm like, well there's that or
it could be really, really hard

525
00:28:49,000 --> 00:28:51,160
ground and operators are getting
the sheets and they're just

526
00:28:51,160 --> 00:28:54,200
winding up the pressures to try
and drill quicker 'cause they're

527
00:28:54,200 --> 00:28:57,320
just frustrated and all that
over feeding causes the drill

528
00:28:57,320 --> 00:29:01,760
holes to start deviating.
And then, so then when?

529
00:29:01,960 --> 00:29:04,400
When you're.
Blasting it it's not how, and

530
00:29:04,400 --> 00:29:06,640
blasting it it's not.
I think you're.

531
00:29:06,640 --> 00:29:09,680
Taking how you think it was.
Well, you think you're taking a

532
00:29:09,680 --> 00:29:12,360
chunk out in the middle.
But it's actually.

533
00:29:12,360 --> 00:29:14,760
Maybe you've actually, you've
actually take it out like this

534
00:29:14,760 --> 00:29:18,680
chunk over here 'cause the holes
have gone like this and it, you

535
00:29:18,680 --> 00:29:22,520
might actually miss bits of all.
So that, and that could affect

536
00:29:22,520 --> 00:29:25,440
the head grade of a is, is drill
hole deviation.

537
00:29:25,440 --> 00:29:28,760
So that's why a lot of them,
they have to, they need to know

538
00:29:28,760 --> 00:29:31,520
if they're breaking through to
the level above like because if

539
00:29:31,520 --> 00:29:33,440
they're not breaking through
when they're supposed to be

540
00:29:33,440 --> 00:29:37,440
breaking through, that means
they've deviated to the side or

541
00:29:37,440 --> 00:29:41,000
something.
So that's, there's a lot of QAQC

542
00:29:41,000 --> 00:29:46,120
that goes into making sure that
like, yes, that's, and that's

543
00:29:46,120 --> 00:29:50,280
the the funniest thing you see.
And you know, we're all culprits

544
00:29:50,280 --> 00:29:55,600
for it was, as I said, you've
got all this prep work that goes

545
00:29:55,600 --> 00:29:58,960
into firing a stoke.
That is what the mine is built

546
00:29:58,960 --> 00:30:02,440
for is fire and a stoke.
And you get to this, get to the

547
00:30:02,440 --> 00:30:05,160
last point and they're like,
Nah, we need it on the deck.

548
00:30:05,240 --> 00:30:08,320
Like there's been months and
months and months of work and

549
00:30:08,320 --> 00:30:09,920
money.
That's gone in being.

550
00:30:09,920 --> 00:30:13,320
Fired and a shift like it needs
to be blown up on the deck.

551
00:30:13,320 --> 00:30:16,760
They call it OK and you get to
it like they're like, Nah, needs

552
00:30:16,760 --> 00:30:20,960
to be on the deck and a shift
and instead of waiting for half

553
00:30:20,960 --> 00:30:25,040
a shift like and to ensure that
everything is done correctly to

554
00:30:25,040 --> 00:30:27,560
make sure that is all blasted
out.

555
00:30:27,760 --> 00:30:30,240
How it's supposed to.
Yeah, because it could fuck up

556
00:30:30,240 --> 00:30:32,680
and leave a big chunk there
that's unblasted.

557
00:30:32,680 --> 00:30:35,440
I've bloody did it.
I did it.

558
00:30:35,440 --> 00:30:38,360
I left a big chunk at de Gruser
that I'm famous for because it

559
00:30:38,360 --> 00:30:42,280
was all rushed and and like, but
all that prep work that's gone

560
00:30:42,280 --> 00:30:45,360
into that point, it's like the
focus should be on making sure

561
00:30:45,360 --> 00:30:49,080
everything is being done
properly to make sure that stoke

562
00:30:49,240 --> 00:30:51,800
is fired because that was what
the hard mine is for.

563
00:30:51,960 --> 00:30:56,000
It's not the jumbo.
It's not, it is firing Stokes

564
00:30:56,520 --> 00:31:00,960
and it sort of gets, yeah, it
gets a lot of between the whole

565
00:31:01,720 --> 00:31:05,960
all like the con like
contractor, like I was there

566
00:31:05,960 --> 00:31:07,480
still a lot when you got the
contractor.

567
00:31:07,480 --> 00:31:09,720
They're like, oh, we just want
to get work done, get motors,

568
00:31:09,720 --> 00:31:13,000
get tons.
Whereas you know, the client who

569
00:31:13,000 --> 00:31:16,440
owns the mine, the client that,
well technically the

570
00:31:16,440 --> 00:31:19,440
shareholders owned the mine.
They they would want the Stoke

571
00:31:19,440 --> 00:31:22,920
to be fired correctly.
It just means waiting 1/2 a.

572
00:31:22,920 --> 00:31:25,880
Shift more Yeah, the client
might want a bloody just get a

573
00:31:25,880 --> 00:31:29,240
bloody record for the week.
Like it's, yeah, it's, it

574
00:31:29,360 --> 00:31:32,920
sometimes gets lost a bit, but
it is the most important thing

575
00:31:32,920 --> 00:31:35,400
on a mine site.
The matter you were talking just

576
00:31:35,400 --> 00:31:39,400
before about sort of the size of
Stokes and that what other

577
00:31:40,000 --> 00:31:44,160
things can impact getting, you
know, tons out of the ground

578
00:31:44,160 --> 00:31:49,800
onto the surface?
How Yeah, the heat and the

579
00:31:49,800 --> 00:31:53,920
ventilation system cause like if
it's, well, if it's hot, it's

580
00:31:53,920 --> 00:31:55,960
hard for everyone to work and
it's just harder to get

581
00:31:55,960 --> 00:31:57,520
everything done 'cause it's
frigging hot.

582
00:31:57,720 --> 00:32:01,000
Yeah and it's just.
But then the ventilation system

583
00:32:01,000 --> 00:32:05,280
is dependent on if you've got a
lot of spread out mining areas

584
00:32:05,280 --> 00:32:09,000
that are have a certain amount
of ventilation to each area, you

585
00:32:09,000 --> 00:32:12,360
might be restricted on how many
trucks you can send down because

586
00:32:12,360 --> 00:32:16,040
each truck has a certain metres
cube to vent that it needs for

587
00:32:16,040 --> 00:32:20,120
that truck to be in the area.
Oh, it's like rated so.

588
00:32:20,120 --> 00:32:22,880
Obviously it's not like you
could send down 10 trucks if you

589
00:32:22,880 --> 00:32:26,000
wanted to because it's it they
need so much vent per truck.

590
00:32:26,080 --> 00:32:28,800
Yeah, yeah.
I think it's like, oh, is it 24

591
00:32:28,800 --> 00:32:32,280
cubes or something per second of
or a truck?

592
00:32:32,280 --> 00:32:36,240
I don't know, but so all that
stuff, you might be ventilation

593
00:32:36,240 --> 00:32:39,120
constrained on how many trucks
you can send down at one time.

594
00:32:39,120 --> 00:32:42,760
So you might have one truck have
to come all the way out before

595
00:32:42,760 --> 00:32:45,280
you can send another one down to
a certain area.

596
00:32:45,360 --> 00:32:46,760
It might be available the
dirt's.

597
00:32:46,760 --> 00:32:49,400
Down the dirt's there, the
boggers there waiting with the

598
00:32:49,520 --> 00:32:52,480
fucking bucket up in the air,
like yeah, so that's

599
00:32:52,800 --> 00:32:56,320
ventilation.
If if you hear it, mine being

600
00:32:56,320 --> 00:33:00,360
like needing ventilation
upgrades or vent constrained or

601
00:33:00,360 --> 00:33:04,840
anything, you know, it's fucking
hard, like, and or it might be

602
00:33:04,840 --> 00:33:09,320
just the deeper it gets, it just
gets too hot to have too many

603
00:33:09,320 --> 00:33:12,520
trucks down there.
So that that's a big one.

604
00:33:12,520 --> 00:33:15,600
And then and that affects your
cycle time.

605
00:33:15,600 --> 00:33:17,960
Like if you can't, can't have
heaps of trucks down in one

606
00:33:17,960 --> 00:33:21,560
area, like and you've got a heap
of dirt development to get out

607
00:33:21,560 --> 00:33:24,840
to get a jumbo going to because
you can't.

608
00:33:25,240 --> 00:33:27,520
That's the thing that it doesn't
get appreciated with production

609
00:33:27,520 --> 00:33:31,040
is like you can't just nip away
at development all day and then

610
00:33:31,120 --> 00:33:32,760
and do production the whole
time.

611
00:33:33,520 --> 00:33:36,120
You might need to go send the
trucks all the development at

612
00:33:36,120 --> 00:33:39,680
the start to get the dirt out to
have enough room in the

613
00:33:39,680 --> 00:33:42,240
stockpile so they can bog the
head and then get the jumbos

614
00:33:42,240 --> 00:33:44,480
back in.
And then they all the trucks go

615
00:33:44,480 --> 00:33:48,200
to production where otherwise
you've got jumbos and that

616
00:33:48,200 --> 00:33:50,880
parked up doing nothing and not
developing the mind.

617
00:33:50,880 --> 00:33:55,520
So it's like all that tied
together and you don't really

618
00:33:55,520 --> 00:33:57,760
know until you unless you've
worked there.

619
00:33:58,040 --> 00:34:02,000
So you won't read it in an
announcement, but anything about

620
00:34:02,600 --> 00:34:04,840
vent constraints, everything,
you know, it's just going to be

621
00:34:04,840 --> 00:34:06,040
a bit hard.
Yeah.

622
00:34:07,040 --> 00:34:11,960
What?
So yeah, spread out mines that

623
00:34:11,960 --> 00:34:15,440
aren't sort of stacked together,
you know, you know, you're going

624
00:34:15,440 --> 00:34:21,040
to need a lot of infrastructure,
like like a lot of different

625
00:34:21,040 --> 00:34:27,080
vent, different pumping.
So if you go like to put like

626
00:34:27,080 --> 00:34:29,840
ventilation in for an area like
you've got to develop down there

627
00:34:29,840 --> 00:34:34,000
just on the secondary vent, like
just vent from ages away that's

628
00:34:34,000 --> 00:34:37,199
blown through a vent bag.
You got to get down there and

629
00:34:37,199 --> 00:34:40,440
then you can't.
Then you can start a rise ball,

630
00:34:40,679 --> 00:34:45,199
which to put like a primary vent
in, but you need the bottom

631
00:34:45,199 --> 00:34:49,040
excavated first and then you got
to pull Raymond out to make it

632
00:34:49,040 --> 00:34:50,840
bigger and then you got to put a
fan on it.

633
00:34:50,840 --> 00:34:54,159
And so like getting all that
ventilation established, the

634
00:34:54,159 --> 00:34:58,160
capital established can take a
lot of time and that can that

635
00:34:58,160 --> 00:35:03,160
can slow the development of the
mime, which means it's you might

636
00:35:03,160 --> 00:35:05,840
be vent constrained, you might
be not where you need to be.

637
00:35:05,840 --> 00:35:09,440
And so trying to get X amount of
tons out just mightn't be

638
00:35:09,440 --> 00:35:12,240
possible till you've got all
this this shit in.

639
00:35:12,240 --> 00:35:17,240
So it's like that's where is a
simple mine that's just a just a

640
00:35:17,240 --> 00:35:21,600
decline going down and one big
fat ore body or multiple ore

641
00:35:21,600 --> 00:35:24,680
bodies next to each other that
you access from the one decline.

642
00:35:24,800 --> 00:35:28,560
Yeah, could be one set of vent
infrastructure for it, one set

643
00:35:28,560 --> 00:35:33,480
of pumping like all the powers
gets fed off from the one place

644
00:35:33,480 --> 00:35:34,800
and.
It's simpler.

645
00:35:34,800 --> 00:35:38,280
It's just easy.
Like it's just nice and simple.

646
00:35:39,480 --> 00:35:42,400
That means if things are easy
and you don't need all that

647
00:35:42,400 --> 00:35:45,800
other shit going on to make
everything else happen, you

648
00:35:45,800 --> 00:35:47,280
should be able to get your dirt
out easy.

649
00:35:47,440 --> 00:35:52,120
Yeah.
So there's like and it's even

650
00:35:52,120 --> 00:35:55,880
like getting the dirt to the
mill, like it's getting the tons

651
00:35:55,880 --> 00:36:00,120
out of the hole are one thing,
but then getting the dirt to the

652
00:36:00,120 --> 00:36:03,000
ROM to the crusher and then into
the mill.

653
00:36:03,000 --> 00:36:04,560
That's another thing because you
don't want fucking.

654
00:36:05,520 --> 00:36:07,000
That's why you get so pushed to
do it.

655
00:36:07,480 --> 00:36:10,280
Well, that's why mind the mill
specialists like you look at the

656
00:36:10,320 --> 00:36:13,800
underground trucks that are
squashed down and driving around

657
00:36:13,800 --> 00:36:16,280
at friggin 15 KS an hour.
I don't know how quick they go

658
00:36:16,280 --> 00:36:18,120
on the surface.
Probably 20 or something.

659
00:36:18,400 --> 00:36:21,200
You know what I'm fucking around
doing that on the surface,

660
00:36:21,200 --> 00:36:22,880
getting it up to the mill.
You just get it.

661
00:36:22,880 --> 00:36:26,440
Like if you're in a pit, you
just put a mini ROM pad in the

662
00:36:26,440 --> 00:36:29,440
pit, dump it there, get back
underground, keep the boggers

663
00:36:29,440 --> 00:36:32,280
going, keep the jumbos going.
You have the salt Bush trucks

664
00:36:32,560 --> 00:36:35,720
tight buggering around with all
that and taking it to the mill.

665
00:36:36,040 --> 00:36:38,360
Like that's why those
underground trucks aren't built

666
00:36:38,360 --> 00:36:40,600
for driving around the surface
wasting their time.

667
00:36:40,600 --> 00:36:43,440
They need to be underground,
they need to be moving dirt and

668
00:36:43,440 --> 00:36:45,800
that's why salt Bush do the
surface stuff.

669
00:36:46,360 --> 00:36:48,160
That's why they're the mind and
mill specialist.

670
00:36:48,320 --> 00:36:50,400
They wouldn't exist if you
didn't need them.

671
00:36:50,680 --> 00:36:52,280
JC.
And they love tons.

672
00:36:52,280 --> 00:36:54,600
Yeah, they love tons.
So pretty much if you want the

673
00:36:54,600 --> 00:36:57,280
best chance of hitting a target,
get saltpush on your mine site.

674
00:36:57,800 --> 00:37:01,440
Anyway, that's I'm dead set
serious when I say that too.

675
00:37:03,480 --> 00:37:08,440
And to divert a little bit, so
now you're down there on, on

676
00:37:08,440 --> 00:37:12,000
your jumbo or your production
rig or or whatever, there's all

677
00:37:12,000 --> 00:37:15,560
these, you know, gear and
machines running around you.

678
00:37:15,560 --> 00:37:18,520
You might be 2300 metres
underground, if not more.

679
00:37:18,960 --> 00:37:21,400
How hot is it under there?
And with all the gear you're

680
00:37:21,400 --> 00:37:23,360
wearing as well, like, how can
you?

681
00:37:24,480 --> 00:37:27,120
Like, what was your experience
of trying to work in those

682
00:37:27,120 --> 00:37:28,320
conditions?
Oh, what?

683
00:37:28,400 --> 00:37:31,240
Does it even like took you?
It takes you to some dark places

684
00:37:31,240 --> 00:37:33,920
at some mines because I've
worked in some fucking hot

685
00:37:33,920 --> 00:37:36,840
mines.
Like, I think I worked, I

686
00:37:37,160 --> 00:37:41,440
finished at a good one that
wasn't that hot, but God, I

687
00:37:41,440 --> 00:37:44,960
worked at friggin between
Telfer, Agnew, Paulsen's and

688
00:37:45,800 --> 00:37:48,840
Golden Grove.
They're all fucking deep hot and

689
00:37:48,920 --> 00:37:55,360
oh, it's yeah, it's freaking and
you it's like.

690
00:37:55,520 --> 00:37:58,040
Precise and you know.
And you're there for 11 and a

691
00:37:58,040 --> 00:38:01,160
bit hours because you don't like
I only ever worked with

692
00:38:01,160 --> 00:38:03,960
contractors.
So you like you freaking work 11

693
00:38:03,960 --> 00:38:06,920
1/2 hours straight like you
don't none of the like you

694
00:38:06,920 --> 00:38:11,360
wouldn't park up for lunch on a
jumbo like that is just you just

695
00:38:11,360 --> 00:38:13,760
don't do it.
Like it's just not how it works.

696
00:38:14,120 --> 00:38:17,200
Like you, you work for, you work
the whole way through and like,

697
00:38:17,440 --> 00:38:20,880
wow, you'll be especially when
you start getting hot because

698
00:38:20,880 --> 00:38:23,360
you get to that point of
especially the first night shift

699
00:38:23,360 --> 00:38:26,120
in back from break because
you're used to being awake in

700
00:38:26,120 --> 00:38:28,400
the day.
You get down there at night and

701
00:38:28,400 --> 00:38:32,600
you are just like, you're just
nauseous, like you're sick and

702
00:38:32,600 --> 00:38:35,520
you start vomiting because your
body's not used to being awake

703
00:38:35,640 --> 00:38:39,000
and then it's hot.
So you just, you just really got

704
00:38:39,000 --> 00:38:41,520
to look after yourself And then
like you get to the, you can get

705
00:38:41,520 --> 00:38:44,440
to the point at the end like
midway through and you, you

706
00:38:44,440 --> 00:38:48,000
start cramping and like 'cause
once you start, you can't sort

707
00:38:48,000 --> 00:38:50,400
of stop cramping.
You got to sort of limp your way

708
00:38:50,400 --> 00:38:54,240
through And like when it's two
and, but then like 2 days into

709
00:38:54,240 --> 00:38:57,280
the swing, you're like your
body's used to it and you can,

710
00:38:57,320 --> 00:39:00,320
you run around, you sweat it
like anything and you're, and

711
00:39:00,320 --> 00:39:01,400
you're fine.
But it's that.

712
00:39:01,800 --> 00:39:05,600
That adjustment period at the
start of being back at work.

713
00:39:05,600 --> 00:39:09,480
Oh, and you got to like and when
you're 'cause I was just bloody

714
00:39:09,520 --> 00:39:13,200
flat out keen as anything.
But if you, if you're too kind

715
00:39:13,200 --> 00:39:15,000
and because you're doing
everything the hard way, because

716
00:39:15,000 --> 00:39:18,680
you're not as you're just, yeah,
you just might know how to do

717
00:39:18,680 --> 00:39:20,160
things properly.
And then you're you're.

718
00:39:20,160 --> 00:39:23,760
Fatigued and then you're just,
oh, you just start, you start

719
00:39:24,640 --> 00:39:28,640
not making decisions properly,
like you just it's such a big

720
00:39:28,640 --> 00:39:31,040
focus trying to keep everyone
bloody.

721
00:39:32,280 --> 00:39:36,840
When it's hot, it's hot, but it
can affect the output of the of

722
00:39:36,840 --> 00:39:38,960
the mind because you've got
people like you've really got to

723
00:39:38,960 --> 00:39:41,800
slow down sometimes or yeah,
like you can't slow down too

724
00:39:41,800 --> 00:39:44,680
much because then you sort of
lose, you become a bit lazy.

725
00:39:44,680 --> 00:39:47,120
Like you got to, you got to move
with the purpose down there

726
00:39:48,000 --> 00:39:50,960
because if you're not like you
mightn't be, you get complacent.

727
00:39:51,080 --> 00:39:52,480
They're like, oh, you got to
slow down.

728
00:39:52,480 --> 00:39:55,080
Think about what you're doing.
Like some I've always believed

729
00:39:55,080 --> 00:39:58,560
you got to you got to work hard
and can be switched on like

730
00:39:58,720 --> 00:40:01,680
hyper because you're thinking
about everything when you.

731
00:40:02,080 --> 00:40:05,000
Go too slow, you get lazy and
that's when shit can happen

732
00:40:05,000 --> 00:40:07,240
sometimes, yeah.
So, yeah, it's.

733
00:40:07,240 --> 00:40:11,160
But then depends on how, depends
on the depth, depends on.

734
00:40:11,160 --> 00:40:15,760
So talking about hate, but you
could have like these shallow

735
00:40:15,760 --> 00:40:21,440
minds that are fucking hot
because they've got all bodies

736
00:40:21,440 --> 00:40:25,000
spread out everywhere and
they've got they've got to try

737
00:40:25,000 --> 00:40:28,160
and independently ventilate.
And I've talked about this these

738
00:40:28,160 --> 00:40:30,840
places before, but you got to
they got to independently

739
00:40:30,840 --> 00:40:34,800
ventilate those areas.
So you need to like dedicated

740
00:40:34,800 --> 00:40:37,840
fan return airway or they might
be reliant on that air to come

741
00:40:37,840 --> 00:40:40,760
back out of that area to flow
down to another area.

742
00:40:41,080 --> 00:40:45,520
So when they're you, you can't
just how a development and even

743
00:40:45,520 --> 00:40:48,240
a production cycle works.
Like there's not just one truck

744
00:40:48,240 --> 00:40:51,200
going down every day and then
throughout the whole day

745
00:40:51,200 --> 00:40:55,120
consistently.
Like when a bogger needs to bog

746
00:40:55,120 --> 00:40:59,000
out a heading and they fill a
stockpile up, they need to get

747
00:40:59,360 --> 00:41:02,080
there could be like 8 trucks
worth of dirt to come out of

748
00:41:02,080 --> 00:41:04,520
that heading, right?
So they don't, you can't just

749
00:41:04,520 --> 00:41:06,920
have one truck go down every
hour because you need to get

750
00:41:06,920 --> 00:41:10,720
that cleaned out as quick as you
can and bogged out so that the

751
00:41:10,720 --> 00:41:13,560
jumbo can get back in there.
So you might have, you know, 3

752
00:41:13,560 --> 00:41:16,800
trucks all going down there at
once, like and they're just load

753
00:41:16,840 --> 00:41:18,600
that one goes out, the other one
comes in.

754
00:41:18,800 --> 00:41:21,680
So you got 3, you've already got
the bogger there generating

755
00:41:21,680 --> 00:41:23,400
heat.
Then you've got all three trucks

756
00:41:23,400 --> 00:41:26,960
going down there, which are all
generating a lot of heat because

757
00:41:26,960 --> 00:41:30,880
they're diesel trucks.
And then that ventilation

758
00:41:30,880 --> 00:41:35,040
system, like the air is there to
try and keep it cool and flush

759
00:41:35,040 --> 00:41:37,760
all the fumes and the heat out.
But if you've got all that down

760
00:41:37,760 --> 00:41:41,000
there, that's that area then
just gets so hot because that's

761
00:41:41,000 --> 00:41:43,560
like the trucks are driving
under the vent bag, which is

762
00:41:43,560 --> 00:41:45,240
heating the air up that's coming
out of there.

763
00:41:45,240 --> 00:41:48,240
So when you're working in that,
so then you might, you Jumbo

764
00:41:48,240 --> 00:41:52,160
might and this is what I talk
about, you know, like say if

765
00:41:52,160 --> 00:41:55,000
they're they're doing production
up one end of the level and then

766
00:41:55,000 --> 00:41:56,480
Jumbo's up the other end of the
level.

767
00:41:56,480 --> 00:41:57,880
This is what Tucker talked
about.

768
00:41:58,240 --> 00:42:01,760
You've got all those, the remote
bogger might fill up the stock

769
00:42:01,760 --> 00:42:05,880
ball and then they they need all
the trucks to come down to bog

770
00:42:05,880 --> 00:42:09,200
it all out, empty the stockpile
so they can start telling

771
00:42:09,200 --> 00:42:12,600
remoting again, which is when
they're on the joysticks in an

772
00:42:12,600 --> 00:42:14,760
open stop.
But all those trucks are coming

773
00:42:14,760 --> 00:42:17,440
down heating up all the vent bag
and everything that's blowing

774
00:42:17,440 --> 00:42:19,400
the air on the jump operator up
the end.

775
00:42:19,720 --> 00:42:24,120
So that's why it's important to
trying to have your development

776
00:42:24,240 --> 00:42:25,840
completely.
Separated from your.

777
00:42:25,840 --> 00:42:28,840
Production like as much as as
best as you can.

778
00:42:28,840 --> 00:42:32,720
So because you're going to get
more out of that operator if

779
00:42:32,720 --> 00:42:36,200
they're not dizzy and hot and
cramping and everything and

780
00:42:36,200 --> 00:42:40,160
they're comfortable, then you
would like yeah, when they you

781
00:42:40,160 --> 00:42:41,640
put them in that environment.
So.

782
00:42:41,920 --> 00:42:47,960
Cause with the ventilation,
like, you know, does like how,

783
00:42:47,960 --> 00:42:53,240
how cool would that make the an,
an underground mine setting?

784
00:42:53,240 --> 00:42:57,080
Or is it just, you know, they
try and keep it at X degrees,

785
00:42:57,080 --> 00:43:00,120
but then, you know, depending on
like as you say, what's going on

786
00:43:00,120 --> 00:43:02,680
in the mine, that sort of ebb
and flow, you know, throughout

787
00:43:02,680 --> 00:43:04,720
the day.
Oh yeah, it depends.

788
00:43:04,720 --> 00:43:06,360
Depends on the surface
temperature.

789
00:43:07,320 --> 00:43:12,680
So 'cause if you've got, you
know, if it's 45° on the

790
00:43:12,680 --> 00:43:16,240
surface, that's 45° dry bulb
that's coming through the

791
00:43:16,240 --> 00:43:17,920
portal.
So you can't really cool it down

792
00:43:17,920 --> 00:43:19,800
from there.
So the, the temperature

793
00:43:19,800 --> 00:43:22,960
underground is more humid
because of the water and yes,

794
00:43:23,400 --> 00:43:26,880
and everything.
So, but then you go, it'll go to

795
00:43:26,880 --> 00:43:30,360
winter and the, the underground
is cooler because the surface is

796
00:43:30,360 --> 00:43:33,000
cool.
So and then in your really,

797
00:43:33,000 --> 00:43:38,400
really deep minds where they
need need refrigeration to cool

798
00:43:38,400 --> 00:43:45,360
the air further, when I remember
at Telfer when the cyclone

799
00:43:45,360 --> 00:43:48,440
season come over, the
refrigeration was an it's like

800
00:43:48,440 --> 00:43:51,480
an evaporative refrigeration,
same as what you have in your

801
00:43:51,480 --> 00:43:53,240
house.
So when it's humid on the

802
00:43:53,240 --> 00:43:56,720
surface, evapor, evaporative air
con doesn't work that well.

803
00:43:56,720 --> 00:44:00,120
So I like the IT wasn't actually
chilling the air that much and

804
00:44:00,120 --> 00:44:04,800
it was it was fucking it's hot.
So mines aren't.

805
00:44:05,080 --> 00:44:10,200
So when you've got spread out
mines, that's just like the

806
00:44:10,200 --> 00:44:13,360
ventilation challenges, the
infrastructure challenges, like

807
00:44:13,360 --> 00:44:17,120
between the pumping the power,
getting it all down there, like

808
00:44:17,600 --> 00:44:20,400
all the machinery having to go
from here and trim all the way

809
00:44:20,400 --> 00:44:22,280
to here.
Like it's you might have the

810
00:44:22,280 --> 00:44:26,760
same amount of gold or copper or
whatever, but it's so much

811
00:44:26,760 --> 00:44:29,120
harder to get to it.
Yeah.

812
00:44:29,200 --> 00:44:32,640
And get work involved to get
that same yeah amount.

813
00:44:32,640 --> 00:44:34,800
And that, and that's why you
look at mines that are just,

814
00:44:35,160 --> 00:44:38,760
they might have all their ore
bodies stacked together or like

815
00:44:38,760 --> 00:44:42,000
it's just one decline that goes
in and you go into a level and

816
00:44:42,280 --> 00:44:46,160
there's just shit loads of gold
or copper on one level and the

817
00:44:46,160 --> 00:44:49,040
trucks just go in and out.
And then they just do another

818
00:44:49,040 --> 00:44:50,400
level.
And they don't have to.

819
00:44:50,880 --> 00:44:54,880
There's one set of there's one
set of pumping infrastructure,

820
00:44:54,880 --> 00:45:00,640
there's one set of power for it.
There's there's like just a big

821
00:45:01,000 --> 00:45:06,400
return airway bent rise.
Like there's just, it's just

822
00:45:06,400 --> 00:45:10,640
easy, like and then the air goes
in to one level, comes back out,

823
00:45:10,640 --> 00:45:14,520
goes down to the other one like,
and it's just simple like.

824
00:45:14,520 --> 00:45:18,880
And so sometimes the most
simplest operations, they

825
00:45:18,880 --> 00:45:22,880
mightn't have high grade, but
they're so much easier to

826
00:45:22,880 --> 00:45:25,400
achieve their targets.
And I think, I think you asked

827
00:45:25,400 --> 00:45:27,720
me this question before and I'll
just ranted on about something

828
00:45:27,720 --> 00:45:31,920
completely different.
But you want to look at from a

829
00:45:32,240 --> 00:45:35,200
investment point of view how a
mine is going to hit their

830
00:45:35,200 --> 00:45:38,040
targets.
It's like, well, how easy is it

831
00:45:38,040 --> 00:45:42,040
for them to get 1,000,000 tonne
out or 1 1/2 or?

832
00:45:42,040 --> 00:45:44,400
What's the work?
Or three million tonne, look at

833
00:45:44,400 --> 00:45:48,800
long Town, everyone's like can
they get 3,000,000 tonne out of

834
00:45:48,800 --> 00:45:53,520
an out of an underground?
If they just put one decline in

835
00:45:53,560 --> 00:45:58,000
to go and had all these trucks
fighting each other up and down,

836
00:45:58,480 --> 00:46:00,240
they would not get 3,000,000
tonne.

837
00:46:00,560 --> 00:46:03,480
But the difference, the thing
that they've done to make it

838
00:46:03,480 --> 00:46:07,200
possible is having like an
update client and a down

839
00:46:07,200 --> 00:46:09,400
decline.
So they've spent the money to.

840
00:46:10,400 --> 00:46:11,480
Simplify the.
Yeah.

841
00:46:11,600 --> 00:46:15,920
So also pretty much every truck
that goes down will go down and

842
00:46:15,920 --> 00:46:20,760
get loaded and then it'll go
around some loop or access the

843
00:46:20,760 --> 00:46:22,840
update client.
So you've just got they're going

844
00:46:22,840 --> 00:46:24,640
in.
So instead of them all going

845
00:46:24,640 --> 00:46:27,440
down and one has to, one has to
pull off to let the other one

846
00:46:27,840 --> 00:46:31,320
passed and like just back and
forth, back and forth, they,

847
00:46:31,320 --> 00:46:34,240
they've just got to have this
circuit where it'll just, and

848
00:46:34,240 --> 00:46:37,400
that, that could be worth, I
don't know, that could be worth

849
00:46:37,400 --> 00:46:40,880
half a million tonne a year just
in efficiency at least.

850
00:46:40,880 --> 00:46:45,880
And that's the thing, it's sort
of hard to quantify the the

851
00:46:45,880 --> 00:46:50,000
benefits or the outcomes of that
because yes, there's obviously

852
00:46:50,000 --> 00:46:53,800
capital involved to put that in
place.

853
00:46:54,280 --> 00:46:56,920
But then it's like, Oh well,
what's my return on it?

854
00:46:56,960 --> 00:47:02,040
And it's sort of hard to, it's
hard to quantify what the, the

855
00:47:02,040 --> 00:47:05,440
benefit is because it's like, Oh
well, because I'm able to get in

856
00:47:05,440 --> 00:47:08,160
and out of the mind quicker.
I'm not getting in people's way,

857
00:47:08,400 --> 00:47:12,280
you know, perhaps I can, you
know, get so much more tons in a

858
00:47:12,280 --> 00:47:14,560
particular shift or a particular
week and stuff.

859
00:47:14,560 --> 00:47:20,040
So yeah, like you'd never really
think to, I guess from my

860
00:47:20,040 --> 00:47:22,840
perspective, think to even like
look at something like that.

861
00:47:22,880 --> 00:47:26,920
Oh, and it's like because they
might need that amount of tons

862
00:47:27,400 --> 00:47:30,680
to like make money like at
scale, like, you know, a gold

863
00:47:30,680 --> 00:47:34,440
mine with all the people and
equipment and everything

864
00:47:34,440 --> 00:47:35,680
provided.
They're not going to just mine

865
00:47:35,680 --> 00:47:38,240
200,000 tonne a year.
It's not going to pay for

866
00:47:38,240 --> 00:47:40,160
everything.
Like they might need to get to

867
00:47:40,160 --> 00:47:41,800
get the share market happy and
everything.

868
00:47:42,080 --> 00:47:44,280
They might need to get 1,000,000
tonne.

869
00:47:44,640 --> 00:47:49,400
But there is so many things that
conhibit that I said like just

870
00:47:49,400 --> 00:47:54,560
all body location when they're
all spread out and that means

871
00:47:54,560 --> 00:47:58,280
there's more capital required to
get to each of them, more vent

872
00:47:58,280 --> 00:47:59,600
required, which costs more
money.

873
00:47:59,600 --> 00:48:02,880
So like your operating costs,
your capital cost goes up and

874
00:48:02,880 --> 00:48:05,720
even probably your operating
cost goes up because it's not as

875
00:48:05,720 --> 00:48:08,760
efficient because you're just
it's all over the shop.

876
00:48:08,760 --> 00:48:11,520
But when you've got a simple
operation, you might need less

877
00:48:11,520 --> 00:48:14,560
machinery to get the same amount
of material out.

878
00:48:14,760 --> 00:48:19,880
And then like it's like ground
hardness like rock like that can

879
00:48:20,080 --> 00:48:24,200
and ground conditions like and
water like as soon as you start.

880
00:48:24,600 --> 00:48:26,760
Water.
Water what's what's it's

881
00:48:27,120 --> 00:48:28,560
probably.
Just a simple.

882
00:48:28,560 --> 00:48:32,280
Question of what what What's the
What's water really important

883
00:48:32,280 --> 00:48:33,800
for underground for those who
don't know.

884
00:48:34,000 --> 00:48:36,360
Well, or you need water to power
the rigs.

885
00:48:36,600 --> 00:48:40,120
Yeah, but then water if there's
too much water and you're trying

886
00:48:40,120 --> 00:48:43,760
to develop a decline, but you
can't pump the water out to have

887
00:48:43,760 --> 00:48:46,800
a clean area down there to put
all the holes in and charge it

888
00:48:46,800 --> 00:48:48,040
all.
You just can't.

889
00:48:48,120 --> 00:48:50,720
It's just a you're in a friggin
standstill nearly.

890
00:48:50,960 --> 00:48:55,040
So water can be waters can be
your biggest.

891
00:48:55,240 --> 00:48:57,360
The only thing you need
waterfalls to, you know, wash

892
00:48:57,360 --> 00:48:58,760
everything down and power the
rigs.

893
00:48:59,400 --> 00:49:02,400
But which is if you don't have
it, you can't do anything.

894
00:49:02,600 --> 00:49:05,280
But then if you have too much of
it coming.

895
00:49:05,280 --> 00:49:08,200
Through the ground.
It completely fucks the joint.

896
00:49:08,200 --> 00:49:10,640
So I'll, I'll take you through
the journey.

897
00:49:10,640 --> 00:49:14,640
If the if you're developing the
ideal mind or the OR a shit one,

898
00:49:15,400 --> 00:49:18,360
and a lot of it's out, it's out
of the owner's control.

899
00:49:18,360 --> 00:49:20,440
It's what was what God put
there.

900
00:49:20,800 --> 00:49:23,200
Yeah.
So you cut the border, which is

901
00:49:23,200 --> 00:49:28,520
the coming in from the surface
or in from in from a pit or

902
00:49:28,520 --> 00:49:30,480
whatever, and you start mining
the.

903
00:49:30,480 --> 00:49:33,520
Front door to the front the.
Front door, best way to put it.

904
00:49:33,840 --> 00:49:37,960
So your ideal situation is like
the ground's nice and competent.

905
00:49:39,160 --> 00:49:42,680
It's not not too hard.
Like if it's too hard, it takes

906
00:49:42,680 --> 00:49:46,960
so long to drill all the holes
and you're just it's, it's just.

907
00:49:47,560 --> 00:49:48,680
You need sort of something in
the middle.

908
00:49:48,680 --> 00:49:51,720
That boring process of showing
for an old drive, you could

909
00:49:51,720 --> 00:49:56,080
either take you, it could take
you an hour in good ground like

910
00:49:56,080 --> 00:49:58,880
just which is easy to get
through, or it might take you 2

911
00:49:58,880 --> 00:50:00,920
hours in if it's really, really
hard.

912
00:50:01,800 --> 00:50:06,240
So that's like that's a lot less
meters per jumbo depending on

913
00:50:06,240 --> 00:50:09,160
the hardness.
So I say you're going through

914
00:50:09,160 --> 00:50:13,400
punching that in like it's all
if it's nice and competent, that

915
00:50:13,400 --> 00:50:16,240
means you don't need shit loads
of ground support.

916
00:50:16,240 --> 00:50:18,400
It's just normal mesh and split
sets.

917
00:50:18,840 --> 00:50:23,920
Whereas if the ground is like
poor and it's falling in or like

918
00:50:23,920 --> 00:50:26,960
you might need to put shock
crate up, which is cement.

919
00:50:26,960 --> 00:50:29,840
So it's like an extra machine
that has an extra cost you have

920
00:50:29,840 --> 00:50:31,680
to put in.
Then you might have to put mesh

921
00:50:31,680 --> 00:50:34,240
over the top of that.
Then you might have to put resin

922
00:50:34,240 --> 00:50:38,800
bolts in, which which take twice
as long, even more than split

923
00:50:38,800 --> 00:50:41,040
sets like it might, and it costs
more.

924
00:50:41,280 --> 00:50:43,000
Oh, it's just because you got to
put the glue in.

925
00:50:43,000 --> 00:50:45,400
Then you got to put the bolt in.
So it's an extra step.

926
00:50:45,600 --> 00:50:49,040
Two steps and then if it's shit
ground you might be scale and

927
00:50:49,040 --> 00:50:54,480
heaps like it's that.
So ideally if it's competent,

928
00:50:54,960 --> 00:50:57,880
you can drill quick enough.
It's not much ground support,

929
00:50:57,960 --> 00:51:01,280
the whole mind just flows.
It's just easy.

930
00:51:02,840 --> 00:51:08,120
And whereas you might have hard
ground in common ground, but it

931
00:51:08,120 --> 00:51:11,600
might, you might drill a 4 1/2
meter hole and I blast out three

932
00:51:11,600 --> 00:51:14,720
meters and you've got all this
shit you got to scale off called

933
00:51:14,720 --> 00:51:18,400
the butt.
So I like the I don't know what

934
00:51:18,400 --> 00:51:23,400
I don't know what the word the
exca Excava excavability.

935
00:51:23,840 --> 00:51:25,960
Not at all.
They're just like the blaster,

936
00:51:26,160 --> 00:51:28,840
how blaster bullet is like some
ground blasts easy.

937
00:51:28,840 --> 00:51:31,960
Some ground is a pain in the ass
to do it.

938
00:51:31,960 --> 00:51:36,040
So and that can fuck you around.
So like your meters advance per

939
00:51:36,040 --> 00:51:38,720
cycle is lower, so you're not
getting as far.

940
00:51:39,080 --> 00:51:44,320
So and then like if the ground
shit like between putting,

941
00:51:44,760 --> 00:51:48,000
putting up extra ground support
takes heaps longer cost heaps

942
00:51:48,000 --> 00:51:50,960
more.
So like the meters you get it,

943
00:51:51,640 --> 00:51:55,600
you know, or like for John D
when I was there, awesome

944
00:51:55,600 --> 00:51:57,800
ground.
Like don't need heaps of ground

945
00:51:57,800 --> 00:51:59,240
support.
There's just, you know, all

946
00:51:59,240 --> 00:52:02,520
drivers, like 3 sheets of mesh
and bloody 20 bolts or

947
00:52:02,520 --> 00:52:05,360
something.
And you, you're in and out in an

948
00:52:05,360 --> 00:52:07,200
hour.
And whereas some mines you might

949
00:52:07,200 --> 00:52:09,760
be balding and heading for five
or six hours because it's got

950
00:52:09,760 --> 00:52:13,520
all these different forms of
ground support and it's all

951
00:52:13,520 --> 00:52:15,560
those factors.
And so now and what the ground

952
00:52:15,560 --> 00:52:19,480
conditions are.
So if I'm looking out of mind to

953
00:52:19,480 --> 00:52:23,160
hit targets, it's like when
they're talking about the

954
00:52:23,160 --> 00:52:26,040
ground, ground's really hard.
So it's really slow or the

955
00:52:26,040 --> 00:52:28,200
ground conditions are poor and
it needs types of ground

956
00:52:28,200 --> 00:52:31,600
support.
And your meters per jumbo are a

957
00:52:31,600 --> 00:52:33,440
lot lower.
Like you just know it's hard

958
00:52:33,440 --> 00:52:36,360
work.
So that means production will

959
00:52:36,360 --> 00:52:38,960
catch up to development quickly.
Everything's going to be on top

960
00:52:38,960 --> 00:52:42,240
of each other.
And so you can sort it from

961
00:52:42,480 --> 00:52:46,640
after working in it and applying
it to because I guess fight like

962
00:52:46,640 --> 00:52:49,520
looking at the financials are
all, you know, backwards looking

963
00:52:49,600 --> 00:52:52,000
like it's like this is how much
it's cost.

964
00:52:52,000 --> 00:52:54,880
This is the this is what the mod
the models are predicting for

965
00:52:54,880 --> 00:52:57,800
the future based on their
guidance and everything.

966
00:52:57,800 --> 00:53:02,120
Like, whereas I think if you
look at the, the ore body and

967
00:53:02,120 --> 00:53:05,560
the mind design and the ground
conditions and it, as I said, if

968
00:53:05,560 --> 00:53:09,600
there's water, like if there's
water, natural water coming in,

969
00:53:09,600 --> 00:53:12,520
that makes everything difficult.
Like controlling that can take

970
00:53:12,520 --> 00:53:14,840
time.
And like all those factors you

971
00:53:14,840 --> 00:53:17,800
think of like you can sort of
analyse like, right?

972
00:53:17,800 --> 00:53:20,680
Can you predict any if this is
going to be an easy mine or a

973
00:53:20,680 --> 00:53:24,960
hard mine, like to hit targets
like, and sometimes the, it's

974
00:53:24,960 --> 00:53:30,040
just the most boring, simple
vertical narrow vine mines that

975
00:53:30,040 --> 00:53:33,360
just keep going and going, just
continue to make money.

976
00:53:34,280 --> 00:53:41,720
And whereas the the ones that
have got shit ground hot, like a

977
00:53:41,720 --> 00:53:45,040
lot of bloody cost of
infrastructures like because

978
00:53:45,040 --> 00:53:48,640
you've got to put that much in
like it just they just seem to

979
00:53:48,640 --> 00:53:52,960
be always chasing their tail.
But then sort of taking it a, a

980
00:53:52,960 --> 00:53:56,200
step back.
So as far as the process, so you

981
00:53:56,200 --> 00:53:59,440
said you open up the, the
portal, the front door to the

982
00:53:59,440 --> 00:54:03,000
underground mine.
Then then what happens after

983
00:54:03,000 --> 00:54:04,280
that?
Because we sort of we sort of

984
00:54:04,280 --> 00:54:06,960
jumped straight to the jumbo and
the production side.

985
00:54:06,960 --> 00:54:09,640
So, so but what happens all
before that, before the the

986
00:54:09,680 --> 00:54:11,440
jumbos and the production rigs
get in?

987
00:54:11,440 --> 00:54:13,160
Well, that the jumbos do in the
portal.

988
00:54:13,160 --> 00:54:14,120
They're they're doing the
portal.

989
00:54:14,120 --> 00:54:16,120
Yeah, so they do that whole
thing the whole way down.

990
00:54:16,120 --> 00:54:19,920
But if, as I said, if the, if
your cycle's taken twice as long

991
00:54:19,920 --> 00:54:23,040
because of shit ground or more
ground support needed, that

992
00:54:23,040 --> 00:54:27,040
means it takes you 2 years to
get to 1st production instead of

993
00:54:27,040 --> 00:54:31,080
one year because you've it takes
you twice as long to develop all

994
00:54:31,080 --> 00:54:33,440
the drives and decline and, and
everything.

995
00:54:33,440 --> 00:54:38,960
So yeah, that's why you know,
for them to companies will say,

996
00:54:39,120 --> 00:54:42,640
oh, we got first production in
November next year, just 12

997
00:54:42,640 --> 00:54:45,040
months away.
They're like, and they finally

998
00:54:45,040 --> 00:54:48,200
just cut the portal.
It's like that's how they can

999
00:54:48,200 --> 00:54:50,120
sort of come unstuck because
they get in there and they're

1000
00:54:50,120 --> 00:54:54,040
like Adriatic perfect example.
They predicted all these things

1001
00:54:54,040 --> 00:54:56,920
began then get down there and
the ground was absolutely shit

1002
00:54:57,360 --> 00:54:59,960
and it just kept all and they
had to put all this extra ground

1003
00:54:59,960 --> 00:55:05,680
support in and everything just
blew out because I think mostly

1004
00:55:05,680 --> 00:55:08,520
a function of ground conditions
that they did not predict.

1005
00:55:08,880 --> 00:55:11,160
And then it just blew out.
Timelines blew out first

1006
00:55:11,160 --> 00:55:14,640
concentrate because you just,
you can only mine as quick as

1007
00:55:14,640 --> 00:55:16,560
the operator and the ground let
you.

1008
00:55:17,920 --> 00:55:21,760
So yeah.
So you cut the portal and then

1009
00:55:21,760 --> 00:55:28,160
the decline is basically the is
that sort of like the could you

1010
00:55:28,160 --> 00:55:30,600
think of it as like the main
freeway that everyone sort of

1011
00:55:30,600 --> 00:55:34,000
comes on and off on to go back
out?

1012
00:55:34,080 --> 00:55:36,400
The good analogies.
Jason, I'm trying to simplify it

1013
00:55:36,400 --> 00:55:38,640
for my brain.
It's like the the decline is the

1014
00:55:38,640 --> 00:55:40,880
freeway and all the levels are
the streets.

1015
00:55:40,880 --> 00:55:42,800
The streets, Yeah.
Oh, that's actually, yeah,

1016
00:55:42,800 --> 00:55:45,280
that's a good visual actually.
That's OK.

1017
00:55:45,280 --> 00:55:49,320
And then you got all the levels
and then sort of as you, you

1018
00:55:49,360 --> 00:55:50,760
pretty much.
You could think like, you could

1019
00:55:50,760 --> 00:55:54,440
think of the ore drives as
Peppermint Drive.

1020
00:55:55,200 --> 00:55:57,480
So what do you that's like,
that's like the Boulevard,

1021
00:55:57,800 --> 00:55:59,880
that's where all the money is.
You've got like, well, West

1022
00:55:59,880 --> 00:56:03,360
Coast Dr. Broome, St.
Mummy and St. the 6011.

1023
00:56:03,360 --> 00:56:06,560
Yeah, all of coming off Stirling
Highway.

1024
00:56:06,600 --> 00:56:10,520
Yeah, yeah.
OK, so that's sort of that's

1025
00:56:10,520 --> 00:56:14,640
actually just visually thinking
about it that like that really

1026
00:56:14,880 --> 00:56:18,840
simplifies it for me.
But actually going, I know we're

1027
00:56:18,840 --> 00:56:21,120
sort of jumping around here, but
just sort of getting in the

1028
00:56:21,120 --> 00:56:24,360
weeds and stuff is awesome.
So like what have you talked

1029
00:56:24,360 --> 00:56:28,960
about before sort of certain
stats, you know, they appear,

1030
00:56:29,360 --> 00:56:32,480
you know, you know, sort of
simple or a bit rudimentary, but

1031
00:56:32,480 --> 00:56:37,160
then what it can perhaps signal
of what's to come with the mine

1032
00:56:37,160 --> 00:56:40,040
or what's sort of happening at
the mine and stuff.

1033
00:56:40,400 --> 00:56:43,880
What are what are some other
ones that are you know or gives

1034
00:56:43,880 --> 00:56:46,720
you, you know, say if in a ramp
up situation that you think, OK,

1035
00:56:47,360 --> 00:56:51,960
ramp up seems to be going well
or things are maybe a bit slower

1036
00:56:52,080 --> 00:56:56,720
than anticipated.
Oh, it's the average metres per

1037
00:56:56,720 --> 00:57:00,560
month per jumbo is usually the
an indicator.

1038
00:57:00,560 --> 00:57:06,280
Like if it's, if the jumbos are
killing it, like just you know,

1039
00:57:06,280 --> 00:57:08,360
there's not many jumbos, they're
getting a lot of metres.

1040
00:57:08,720 --> 00:57:12,000
That's an indication straight
away that oh, the ground's good.

1041
00:57:12,080 --> 00:57:14,400
Like it's obviously.
They're working their way

1042
00:57:14,480 --> 00:57:16,440
through.
Easy digging and means like, oh,

1043
00:57:16,440 --> 00:57:19,480
they obviously don't need too
much ground support like so the

1044
00:57:19,480 --> 00:57:24,640
ground conditions must be good.
You know that you know, if

1045
00:57:24,680 --> 00:57:26,520
they're they're in the four
hundreds or something, you're

1046
00:57:26,520 --> 00:57:28,440
like, oh shit, that's bloody,
that's good gun.

1047
00:57:28,440 --> 00:57:34,000
Well, that's whereas, you know,
if they've struggling to get

1048
00:57:34,000 --> 00:57:38,200
300, you're like, OK, why are
they only getting 300?

1049
00:57:38,200 --> 00:57:40,440
Is it do they need a lot of
ground support?

1050
00:57:41,280 --> 00:57:46,680
Is the ground really hard?
Is you know, is it really spread

1051
00:57:46,680 --> 00:57:48,600
out?
Like is that the issue?

1052
00:57:49,880 --> 00:57:53,800
Is how does someone like me know
how much meters a jumbo should

1053
00:57:53,800 --> 00:57:56,760
be doing a a month or 1/4 at a
particular mine?

1054
00:57:56,800 --> 00:57:59,080
Oh just do they know?
Does the company normally say

1055
00:57:59,120 --> 00:58:01,280
this is?
No, it just says, oh, they'll

1056
00:58:01,280 --> 00:58:03,680
say it in the feasibility study
and everything, but it's just

1057
00:58:03,680 --> 00:58:06,520
based on knowing what a jumbo
can achieve.

1058
00:58:07,600 --> 00:58:11,600
And, you know, normally they've,
if they've got good, good people

1059
00:58:11,600 --> 00:58:13,480
there, like they're, they want
to achieve.

1060
00:58:13,480 --> 00:58:15,400
And like, there's, you know,
there's obviously different

1061
00:58:15,400 --> 00:58:18,840
levels of skills.
Like there's you, they pay shit

1062
00:58:18,840 --> 00:58:21,440
loads that are, you know, going
to get that are going to get

1063
00:58:21,440 --> 00:58:23,320
more and that bring good people
with them.

1064
00:58:23,680 --> 00:58:26,680
Or if they're just they're not
going to pay shit loads, they

1065
00:58:26,680 --> 00:58:30,120
might get someone a bit down the
run that and it just doesn't

1066
00:58:30,120 --> 00:58:33,160
flow as much.
But it's, it's a money trade

1067
00:58:33,160 --> 00:58:37,440
off.
But it's that, that's, that's

1068
00:58:37,560 --> 00:58:40,360
sort of one that because that's
the hardest thing in like

1069
00:58:40,440 --> 00:58:42,880
quarterlies and that like
they're not going to, they don't

1070
00:58:42,880 --> 00:58:47,640
go into too much detail, but you
want to know, it's just sort of

1071
00:58:47,640 --> 00:58:52,960
a bit of an indicator on how
the, because so if the, if the

1072
00:58:52,960 --> 00:58:55,320
ground can, if they're not
putting much ground support up,

1073
00:58:55,320 --> 00:58:58,960
but they're still not getting
heaps of metres, that means

1074
00:58:58,960 --> 00:59:01,640
that, OK, the ground's obviously
really hard.

1075
00:59:02,440 --> 00:59:05,520
And so that that's making it
slow for the jumbos, which means

1076
00:59:05,520 --> 00:59:08,280
OK, that's going to make it slow
for the jumbos to get ahead of

1077
00:59:08,280 --> 00:59:10,400
production.
And production and development

1078
00:59:10,400 --> 00:59:12,880
are always going to be fighting.
It's going to be hard to get

1079
00:59:12,880 --> 00:59:16,800
sort of a consistency.
And it might and it might, you

1080
00:59:16,800 --> 00:59:20,440
know, I mean that it's really
hard and holes might deviate if

1081
00:59:20,440 --> 00:59:23,880
they overfeed or, or whatever,
like, and it's just like, oh,

1082
00:59:23,960 --> 00:59:28,320
it's like, fuck, there's could
be some dramas coming up.

1083
00:59:28,320 --> 00:59:31,160
And then or if it says they're
putting in lots of ground

1084
00:59:31,160 --> 00:59:35,320
support because the ground
conditions are poor, it's like,

1085
00:59:35,320 --> 00:59:37,600
OK, well, if the ground
conditions are poor in

1086
00:59:37,600 --> 00:59:40,280
development, that means when
they go into production, they're

1087
00:59:40,280 --> 00:59:41,720
probably going to be poor as
well.

1088
00:59:42,320 --> 00:59:45,760
It usually, usually Adriatic was
actually the other way around.

1089
00:59:45,760 --> 00:59:48,120
There was poor ground conditions
in the capital, but the ground

1090
00:59:48,120 --> 00:59:51,400
got actually good in the ore,
which is oh, OK, yeah,

1091
00:59:51,400 --> 00:59:54,640
completely the opposite.
So that then you can infer from

1092
00:59:54,640 --> 00:59:57,840
that, OK, if the ground
conditions are poor, that means

1093
00:59:58,480 --> 01:00:01,680
it may dilute the grade of the
reserve.

1094
01:00:01,680 --> 01:00:05,760
The reserve might apply. 10 to
20% unplanned dilution, that

1095
01:00:05,760 --> 01:00:08,040
might be high.
So that may might mean the head

1096
01:00:08,040 --> 01:00:11,680
grade might be lower going
through the mill.

1097
01:00:11,680 --> 01:00:14,800
It's like, OK, that means there
might be a risk of not hitting

1098
01:00:14,800 --> 01:00:18,800
guidance and so you can sort of
use all that.

1099
01:00:18,880 --> 01:00:21,720
Just a bit of a leading
indicator of what might be

1100
01:00:21,720 --> 01:00:24,120
happening along the way.
Yeah, yeah.

1101
01:00:24,120 --> 01:00:25,880
And it's like, and they're,
they're never going to really

1102
01:00:26,000 --> 01:00:28,400
tell like you'd probably see
from a site visit the level of

1103
01:00:28,400 --> 01:00:32,480
ground support that goes in and
they're not going to really

1104
01:00:32,520 --> 01:00:35,160
disclose all the details of
like.

1105
01:00:35,160 --> 01:00:37,400
That level of granularity.
Yeah, yeah.

1106
01:00:37,400 --> 01:00:40,760
And it's like that you, you
know, and because a lot of these

1107
01:00:40,760 --> 01:00:46,600
mines are restarts, like, like
you knew Bellevue was hard

1108
01:00:46,600 --> 01:00:49,360
before Bellevue started because
it was a historical mine.

1109
01:00:49,800 --> 01:00:52,280
So all the people that used to
work in it were like, oh, it's

1110
01:00:52,280 --> 01:00:57,320
bloody hard as anything, you
know, like Andy, Well, for

1111
01:00:57,320 --> 01:01:00,440
instance, that's a race start.
People have worked there before,

1112
01:01:00,440 --> 01:01:02,960
like the and the ground was
laminated.

1113
01:01:02,960 --> 01:01:04,880
Then I assume it still is
laminated.

1114
01:01:06,120 --> 01:01:11,800
So like you, that's the thing.
It's like, it's not like, I

1115
01:01:11,840 --> 01:01:14,280
don't know, you can ask people
that have worked, worked, worked

1116
01:01:14,280 --> 01:01:16,840
at these places 20 years ago.
What was that joint like to work

1117
01:01:16,840 --> 01:01:17,720
out?
What were the issues?

1118
01:01:17,720 --> 01:01:19,200
They're like, oh, yada, yada,
yada.

1119
01:01:19,720 --> 01:01:24,200
I don't think it's, I don't
think that's illegal to like ask

1120
01:01:24,200 --> 01:01:25,880
someone that's worked in a mine
before.

1121
01:01:25,880 --> 01:01:28,800
What was the ground like?
It's just a personal

1122
01:01:28,800 --> 01:01:30,280
conversation.
Yeah.

1123
01:01:30,600 --> 01:01:35,880
And then so the actual, the sort
of the the mining, the

1124
01:01:35,880 --> 01:01:38,920
underground mining method, I
mean we sort of ran through it A

1125
01:01:39,240 --> 01:01:43,760
at a high level just sort of as
we're chatting is that is that

1126
01:01:43,760 --> 01:01:46,120
the only way you can mine
underground?

1127
01:01:46,120 --> 01:01:49,720
I imagine there's, you know, you
hear the terms like block caving

1128
01:01:49,720 --> 01:01:53,960
and other sorts of things.
So is that just because I heard,

1129
01:01:54,000 --> 01:01:58,560
is it long haul open soaping is
that's what you've described?

1130
01:01:58,560 --> 01:02:01,200
Yeah, yeah, pretty much that.
And that's the most common one

1131
01:02:01,200 --> 01:02:04,120
in Australia.
It's long haul open stopping.

1132
01:02:04,120 --> 01:02:08,520
It's just, yeah, it's just
mining, mining the veins out for

1133
01:02:09,720 --> 01:02:11,560
whatever commodity you're mining
where.

1134
01:02:11,560 --> 01:02:16,840
But when it's like bulk, like a
copper gold porphyry or like a

1135
01:02:16,840 --> 01:02:20,120
big bulk ore body, that's when
your cavings come into it.

1136
01:02:20,120 --> 01:02:22,240
Like our gold diamond mine that
was a block cave.

1137
01:02:22,240 --> 01:02:24,560
It was just because it's like a
diamond.

1138
01:02:24,680 --> 01:02:28,960
The pipe they just block caved
the pipe Telfer.

1139
01:02:29,160 --> 01:02:32,280
Telfer was actually the sub
level cave, which is it's

1140
01:02:33,080 --> 01:02:35,440
different to a block cave.
You just mine the levels and

1141
01:02:35,760 --> 01:02:38,480
like instead of going all the
way to the bottom and letting

1142
01:02:38,480 --> 01:02:41,600
the whole thing cave you just
sort of you still mine each

1143
01:02:41,600 --> 01:02:45,080
level and then it gradually just
caves down and you just follow

1144
01:02:45,080 --> 01:02:47,240
it down a bit different.
You just still develop every

1145
01:02:47,240 --> 01:02:49,600
level.
Go watch a video on YouTube if

1146
01:02:49,600 --> 01:02:50,880
anyone wants to know the
difference.

1147
01:02:51,840 --> 01:02:58,800
But I think that was just a heap
of gold vines like in an area.

1148
01:02:58,800 --> 01:03:01,280
And it's like, well, instead of
mining them independently and

1149
01:03:01,280 --> 01:03:05,000
fucking around, we'll just take
it all together as a bulk low

1150
01:03:05,000 --> 01:03:10,800
grade operation like Leinster
Perseverance, the nickel

1151
01:03:10,920 --> 01:03:14,000
operation.
That was a sub level cave like

1152
01:03:14,000 --> 01:03:17,880
Maggie Hayes, which was all I
think it was like Nora List.

1153
01:03:17,880 --> 01:03:19,400
The Russians owned that back in
the day.

1154
01:03:19,400 --> 01:03:20,880
I think that was a sub level
cave.

1155
01:03:21,640 --> 01:03:25,120
I think Redeemer back in the day
that was a sub level cave.

1156
01:03:25,120 --> 01:03:27,200
I think it's some other ones
around.

1157
01:03:27,280 --> 01:03:30,760
And like you know, your big sub
level caves and block caves in

1158
01:03:30,760 --> 01:03:35,360
Australia or Arcadia.
That's like the like even

1159
01:03:36,400 --> 01:03:41,400
Tanami, like that's a big a big
mine that's still open stopping.

1160
01:03:41,400 --> 01:03:44,560
Like that's not caved.
That's a big pretty big decent

1161
01:03:44,560 --> 01:03:47,000
ore body.
That's still mind is stopping.

1162
01:03:47,000 --> 01:03:50,320
It just just depends.
But you'd pick the the

1163
01:03:50,400 --> 01:03:56,040
underground mining method based
on the ore body.

1164
01:03:56,120 --> 01:03:59,080
The ore body show Ernest Henry,
that was another sub level cave

1165
01:03:59,880 --> 01:04:01,840
that's like, yeah, ore body
shape.

1166
01:04:01,840 --> 01:04:05,520
Like who's doing it?
Like to do a block cave it has

1167
01:04:05,520 --> 01:04:11,320
to be done by a a Newmont or a
BHP or a Rea because they have

1168
01:04:11,320 --> 01:04:14,520
the capital and the money behind
them to develop all the way down

1169
01:04:14,520 --> 01:04:16,760
to the bottom and not make any
money for.

1170
01:04:17,560 --> 01:04:18,520
Ages.
Yep.

1171
01:04:18,520 --> 01:04:24,240
And then create a block cave,
whereas a bloody Northern Star

1172
01:04:24,400 --> 01:04:26,600
might.
They're not at that scale.

1173
01:04:26,600 --> 01:04:30,360
They're like now we want cash
flow, now we're going.

1174
01:04:30,360 --> 01:04:33,640
To develop aggressively.
Friggin soaping operation or a

1175
01:04:33,640 --> 01:04:38,760
sub level cave because we want
cash now just but it is all body

1176
01:04:38,760 --> 01:04:41,440
dependent but a lot who's minded
it as well.

1177
01:04:42,240 --> 01:04:46,360
And then the the last question
I'd like to ask you, and I think

1178
01:04:46,360 --> 01:04:48,200
we've also gone for around an
hour as well.

1179
01:04:50,000 --> 01:04:56,240
What's something or a couple of
things about underground mining

1180
01:04:57,600 --> 01:05:03,560
that are really underappreciated
that you want people to know If

1181
01:05:03,560 --> 01:05:06,960
you could stand in the middle of
Saint George's Terrace To all

1182
01:05:06,960 --> 01:05:10,400
the brokers and the bankers who
just like maybe don't understand

1183
01:05:10,400 --> 01:05:14,120
this as well and go, you know,
you need to know about this.

1184
01:05:14,120 --> 01:05:15,640
This is this is really
important.

1185
01:05:15,640 --> 01:05:19,000
You need to appreciate this.
Yeah, well it's all we've talked

1186
01:05:19,000 --> 01:05:20,680
about a bit today.
Like it's funny.

1187
01:05:20,680 --> 01:05:27,120
Safety is like, you know, it is
at the top of top of the bloody

1188
01:05:27,120 --> 01:05:28,960
announcement.
Usually there we take the piss

1189
01:05:28,960 --> 01:05:31,920
out of it a bit.
But if you're not having

1190
01:05:31,920 --> 01:05:35,920
incidents on site it means
management aren't fucking around

1191
01:05:35,920 --> 01:05:39,200
doing icams and like having
people in the office.

1192
01:05:39,240 --> 01:05:41,640
OK, sorry, it's.
Like a safety investigation

1193
01:05:41,640 --> 01:05:44,280
process, OK, incident
investigation process.

1194
01:05:45,520 --> 01:05:47,320
If they're bugging around doing
all that shit, they're not

1195
01:05:47,320 --> 01:05:50,000
focusing on mining.
So if there's like a a site that

1196
01:05:50,000 --> 01:05:53,480
doesn't have many incidents, the
whole everything just flows.

1197
01:05:53,480 --> 01:05:55,640
Everything's easy.
No one's hurting for themselves.

1198
01:05:55,640 --> 01:05:57,840
Like, you know, things are
getting done right.

1199
01:05:58,560 --> 01:06:03,880
That's that's a a thing that's
probably under appreciated from

1200
01:06:04,160 --> 01:06:07,320
the investor side.
It's just a it's just a bit of a

1201
01:06:07,320 --> 01:06:10,640
number.
But and obviously you don't, you

1202
01:06:10,640 --> 01:06:14,160
do not want people going up
there being hurt or worse.

1203
01:06:14,520 --> 01:06:17,440
Yes, trying to earn a living
like it's just freaking

1204
01:06:17,480 --> 01:06:19,000
horrible.
Absolutely.

1205
01:06:19,480 --> 01:06:23,760
So that, and that's, but the
success of a mine is like, you

1206
01:06:23,760 --> 01:06:28,680
know, is the safe, the safest
minds and the happiest minds is

1207
01:06:28,680 --> 01:06:32,720
some are usually the most
productive and the most, which

1208
01:06:32,840 --> 01:06:34,520
return more money to
shareholders.

1209
01:06:35,280 --> 01:06:39,240
Like hate like, and, and that's
what like these models and

1210
01:06:39,240 --> 01:06:43,000
everything when they people dish
management, they're like, oh,

1211
01:06:43,000 --> 01:06:45,800
manage, that's management's job.
As in like the fucking managing

1212
01:06:45,800 --> 01:06:47,960
director or whatever.
This one person.

1213
01:06:48,320 --> 01:06:50,920
Well, as I said, there are
hundreds of people working on

1214
01:06:50,920 --> 01:06:55,160
these mine sites and there's so
many layers of middle management

1215
01:06:55,160 --> 01:06:59,680
that are trying to get all these
things to happen to deliver

1216
01:07:00,760 --> 01:07:06,320
1,000,000 tonne to the mill and
150,000 oz like it is.

1217
01:07:07,240 --> 01:07:09,840
There is so much that goes into
it and then.

1218
01:07:09,840 --> 01:07:13,360
So many variables to control and
some that are out of your

1219
01:07:13,360 --> 01:07:15,640
control.
Oh, mate, and the, and the, the

1220
01:07:15,640 --> 01:07:19,680
pressure and responsibility on
the management, especially like

1221
01:07:19,680 --> 01:07:23,960
the, the senior execs here like
that are employing a lot of

1222
01:07:23,960 --> 01:07:26,880
people and that employ a lot of
people and have to trust these

1223
01:07:26,880 --> 01:07:30,160
people to do their job.
So the person below them does

1224
01:07:30,160 --> 01:07:35,560
their job and everyone does
their job to get the figures to

1225
01:07:35,560 --> 01:07:39,280
get it done safely, so they can
report to the market that

1226
01:07:39,720 --> 01:07:45,280
they've hit guidance or they've
just misguided.

1227
01:07:45,720 --> 01:07:48,360
And what goes into that number
is phenomenal.

1228
01:07:48,360 --> 01:07:50,680
And I just don't think people
appreciate it.

1229
01:07:50,680 --> 01:07:55,600
So when they sort of hang shit
on management and about like

1230
01:07:55,600 --> 01:07:57,880
poor management and poor
decisions and like they start

1231
01:07:57,880 --> 01:08:00,360
becoming a bit of a scapegoat.
It's all from people that

1232
01:08:00,360 --> 01:08:02,880
haven't been there and done it.
Like once you've been there and

1233
01:08:02,880 --> 01:08:06,040
done it and watched it and being
involved in it, there is so much

1234
01:08:06,040 --> 01:08:08,480
that goes into it.
So yes, it is shareholder money

1235
01:08:08,800 --> 01:08:12,120
that can be affected by, you
know, over promotion and and

1236
01:08:12,120 --> 01:08:14,160
things like that.
But fuck me, there's a lot of

1237
01:08:14,160 --> 01:08:18,920
people that work their ass off
and away from their family and

1238
01:08:18,920 --> 01:08:23,840
everything to get make all that
happen that just sort of get

1239
01:08:23,840 --> 01:08:25,960
consumed by a number at the end
of the quarter.

1240
01:08:26,120 --> 01:08:29,399
So yeah, it's maybe that's why
I'm a bit softer.

1241
01:08:30,000 --> 01:08:33,240
But what's the other one like?
Yeah, hey, we talked about hate

1242
01:08:33,760 --> 01:08:39,560
barking hard work like that's
and what else?

1243
01:08:40,960 --> 01:08:45,000
Oh, the amount of just probably
the amount of the service

1244
01:08:45,000 --> 01:08:49,520
providers that go into making
mines possible and like the the

1245
01:08:49,520 --> 01:08:52,479
amount of people that are like
contracting and being a service

1246
01:08:52,479 --> 01:08:53,640
provider.
It's not they're all not

1247
01:08:53,640 --> 01:08:56,080
millionaires.
A lot of them have might be

1248
01:08:56,080 --> 01:08:59,080
freaking strung out 90 days
waiting for payments from mining

1249
01:08:59,080 --> 01:09:00,600
companies.
Family businesses.

1250
01:09:00,600 --> 01:09:03,479
Yeah, like, and there's some
people that have just got it on

1251
01:09:03,479 --> 01:09:06,200
the line.
They might get rich when they're

1252
01:09:06,200 --> 01:09:09,600
60, but far out.
There's some people that have

1253
01:09:09,600 --> 01:09:14,680
some bloody minerals to, you
know, assist the mining

1254
01:09:14,680 --> 01:09:16,680
industry.
So pay your invoices on time.

1255
01:09:17,040 --> 01:09:20,439
Mining companies don't fuck
around with trade payables, but

1256
01:09:20,439 --> 01:09:23,520
look after the small businesses.
Fuck what else?

1257
01:09:24,160 --> 01:09:25,240
I don't know.
That's good.

1258
01:09:25,240 --> 01:09:27,600
Fucking love mining.
Love it, love it.

1259
01:09:27,600 --> 01:09:30,040
It's been frigging good to me.
I wouldn't be sitting here doing

1260
01:09:30,040 --> 01:09:32,160
this if it wasn't for the mining
industry.

1261
01:09:32,640 --> 01:09:36,880
There's a lot of shit that goes
around about it, but I can what?

1262
01:09:36,920 --> 01:09:39,000
He makes this fucking country
great.

1263
01:09:39,000 --> 01:09:40,040
Go Australia.
Go.

1264
01:09:40,160 --> 01:09:43,200
Australian go mining.
That was that was awesome.

1265
01:09:43,200 --> 01:09:49,040
I I just like you said the other
day, I I was fascinated by that.

1266
01:09:49,040 --> 01:09:53,160
I think I'll for me, I kind of
I've knew bits and pieces and

1267
01:09:53,160 --> 01:09:56,600
then some of the the bits that
sort of join it together sort of

1268
01:09:56,600 --> 01:10:00,880
got really clarified and really
solidified in my mind today.

1269
01:10:00,880 --> 01:10:02,200
So that was, that was.
Awesome.

1270
01:10:02,280 --> 01:10:04,560
Oh, and it's like as it's trying
to condense and I think it was a

1271
01:10:04,560 --> 01:10:07,560
comment on the YouTube like
you're trying to condense like I

1272
01:10:07,560 --> 01:10:10,280
only did it 14 years, which is
actually probably not.

1273
01:10:10,280 --> 01:10:13,760
That is not that long compared
to people that have been in the

1274
01:10:13,760 --> 01:10:16,120
industry.
And like just the fucking, the

1275
01:10:16,120 --> 01:10:20,720
info you can absorb in that time
is like trying to explain it.

1276
01:10:21,320 --> 01:10:25,360
It's just every time I look at
a, an announcement or something,

1277
01:10:25,360 --> 01:10:27,760
you sort of apply it to a
historical learning.

1278
01:10:28,520 --> 01:10:30,640
Oh, that was hard at that joint.
Is that going to be hard at

1279
01:10:30,640 --> 01:10:32,320
that, like difficult at that
joint?

1280
01:10:33,160 --> 01:10:35,240
Oh, that was that looks like
this place that was easy.

1281
01:10:35,240 --> 01:10:37,400
Or is that going to be easy like
it's yeah.

1282
01:10:37,400 --> 01:10:40,440
And it's just based on what
you've seen or what you've

1283
01:10:40,440 --> 01:10:42,880
heard.
So just keep your ears open,

1284
01:10:42,880 --> 01:10:45,200
everyone.
Just talk, talk to talk to

1285
01:10:45,200 --> 01:10:48,000
everyone.
You can learn something off

1286
01:10:48,000 --> 01:10:51,040
everyone.
Especially, you know, I think

1287
01:10:51,040 --> 01:10:54,320
you've mentioned this on the on
the show before, like you, you

1288
01:10:54,320 --> 01:10:57,760
come across miners or operators
that have been, you know, doing

1289
01:10:57,760 --> 01:11:03,440
this for 30-40, you know, maybe
even longer years and, you know,

1290
01:11:04,200 --> 01:11:07,600
listen to what they have to say.
You know, they've they've seen a

1291
01:11:07,600 --> 01:11:11,680
lot.
So I mean, I don't think 14

1292
01:11:11,680 --> 01:11:13,520
years is anything to snooze at
anyway.

1293
01:11:13,520 --> 01:11:15,400
So I'm sure the money might have
got.

1294
01:11:15,400 --> 01:11:16,680
To learn.
Hey, the last one.

1295
01:11:16,840 --> 01:11:19,880
The last one, that's all that
counts, going out on a high.

1296
01:11:20,600 --> 01:11:21,800
Oh daddy, I wasn't even that
good.

1297
01:11:22,160 --> 01:11:24,320
Yeah, now I enjoyed it, but it
was freaking good fun.

1298
01:11:24,320 --> 01:11:26,520
Don't miss getting up at 3:45,
that's for sure.

1299
01:11:26,960 --> 01:11:30,680
Yeah, that'd be a nice
refreshing change being back in

1300
01:11:30,680 --> 01:11:33,160
Perth.
Oh, now, now I'm just a now I'm

1301
01:11:33,160 --> 01:11:34,680
just looking at gold
exploration.

1302
01:11:36,720 --> 01:11:38,200
Oh.
Oh, love it.

1303
01:11:38,720 --> 01:11:40,840
Oh, should we do?
What could we could do?

1304
01:11:40,840 --> 01:11:44,200
Rapid fire, right buddy?
Just to finish it off, just.

1305
01:11:44,240 --> 01:11:46,560
To to finish it off.
Yeah, it's pretty much Jake

1306
01:11:46,560 --> 01:11:49,480
Klein stepping down as to non
exact.

1307
01:11:49,960 --> 01:11:50,880
Yeah.
So, Jake.

1308
01:11:50,880 --> 01:11:54,600
Evolution.
And they had a a pretty record

1309
01:11:54,600 --> 01:11:59,200
half one for FY25 evolution.
So literally.

1310
01:11:59,200 --> 01:12:00,640
Doubled the dividend I or
something?

1311
01:12:00,640 --> 01:12:04,040
They nearly tripled it.
Yeah, no, no huge increase

1312
01:12:04,040 --> 01:12:06,120
there.
So it was sort of the, yeah, the

1313
01:12:06,120 --> 01:12:10,000
main news which I think was sort
of largely anticipated by the

1314
01:12:10,000 --> 01:12:11,880
market.
You know, Jake, the exec chair

1315
01:12:11,880 --> 01:12:16,560
moving to non exec chair, you
know, the financial results, you

1316
01:12:16,560 --> 01:12:22,000
know, you know, statutory net
profit, $365 million, you know,

1317
01:12:22,240 --> 01:12:25,880
underlying EBITDA, you know,
just over a billion, a record

1318
01:12:25,880 --> 01:12:29,400
group cash flow 273,000,000 all
up, up, up, up, up.

1319
01:12:29,400 --> 01:12:33,320
So that's was all very exciting.
And they announced the seven

1320
01:12:33,320 --> 01:12:37,160
cent interim dividend gearing's
down.

1321
01:12:37,160 --> 01:12:39,680
They're sort of targeting to get
that down to 20%.

1322
01:12:39,680 --> 01:12:43,240
It's currently 23.
So they're targeting get that

1323
01:12:43,240 --> 01:12:48,240
20% by the end of this financial
year guidance, looking all on

1324
01:12:48,240 --> 01:12:50,680
track to deliver that for this
financial year.

1325
01:12:52,000 --> 01:12:55,960
Just a quick round up of what
happened at HS at this house.

1326
01:12:55,960 --> 01:13:00,160
SoCal got that regulatory
approval to extend the open peer

1327
01:13:00,160 --> 01:13:05,200
operations by 10 years and the
overall operations to 2042 FID

1328
01:13:05,720 --> 01:13:08,720
the June 25 quarter.
And I think they got an

1329
01:13:08,720 --> 01:13:11,800
annualised mining rate of
2,000,000 tonnes.

1330
01:13:11,800 --> 01:13:14,920
So that's sort of a $0.25
increase in gold production

1331
01:13:14,920 --> 01:13:16,760
there.
Ernest Henry was pretty

1332
01:13:16,760 --> 01:13:20,480
consistent.
N Parks seems to be doing pretty

1333
01:13:20,480 --> 01:13:22,840
well.
They generated $122 million in

1334
01:13:22,840 --> 01:13:25,000
cash flow since they bought that
asset.

1335
01:13:26,920 --> 01:13:30,240
Red Lake is starting to
demonstrate some operational

1336
01:13:30,240 --> 01:13:32,760
consistency.
So they had a a record half year

1337
01:13:33,320 --> 01:13:36,800
net mine cash flow, 44 mil gold
production up 38%.

1338
01:13:37,440 --> 01:13:40,240
That Mongari mill expansion,
which you don't sort of see this

1339
01:13:40,240 --> 01:13:44,120
everyday, nine months ahead of
schedule and about $15 million

1340
01:13:44,120 --> 01:13:45,680
below budget.
There you go.

1341
01:13:45,680 --> 01:13:48,920
How good's that?
Oh, and then Mount Mount Rawdon

1342
01:13:49,240 --> 01:13:51,400
mining ceased.
So that's sort of transitioning

1343
01:13:51,400 --> 01:13:56,120
to stockpile processing there.
And we're to come this quarter.

1344
01:13:56,120 --> 01:13:58,640
There's some studies on
extensions at North Park St.

1345
01:13:58,760 --> 01:14:01,880
Ernest Henry.
Saint Barbs.

1346
01:14:02,040 --> 01:14:05,040
Yes.
So they're they're saying

1347
01:14:05,040 --> 01:14:08,720
goodbye to they would Atlantic
gold operation.

1348
01:14:08,720 --> 01:14:11,960
So they announced today their
intention to sort of separate

1349
01:14:11,960 --> 01:14:16,200
the Atlantic gold OPS.
So this includes 15 mile Beaver

1350
01:14:16,200 --> 01:14:19,640
Dam and Cochrane Hill projects
in Canada from the company

1351
01:14:19,640 --> 01:14:23,040
following a portfolio review.
They basically suggested that as

1352
01:14:23,040 --> 01:14:26,080
part of that portfolio review
that it you know, would better

1353
01:14:26,080 --> 01:14:30,000
maximise shareholder value by
advancing Atlantic under you

1354
01:14:30,000 --> 01:14:34,120
know a Canadian company with
local leadership, you know via

1355
01:14:34,120 --> 01:14:38,800
some sort of a sale or a vending
or a demerger sort of potential

1356
01:14:38,800 --> 01:14:45,000
ways to to do that.
So once that is done, their sole

1357
01:14:45,000 --> 01:14:49,040
focus would be on their Simberry
operation in the PNG.

1358
01:14:49,120 --> 01:14:51,320
So that's it, St.
Barbara will just be Simberry.

1359
01:14:51,480 --> 01:14:53,520
Yeah.
So it's sort of, you know, Guali

1360
01:14:53,520 --> 01:14:57,520
and all that went to Genesis
this they've flagged that they

1361
01:14:57,520 --> 01:14:59,520
wanna sort of separate their
landing stuff.

1362
01:14:59,520 --> 01:15:03,760
So it's due back to or not back
to, but it's now just Simberry

1363
01:15:03,760 --> 01:15:06,840
as you said, so and it's just
quite amazing.

1364
01:15:06,840 --> 01:15:10,800
That's sort of less than six
years ago after acquiring it, I

1365
01:15:10,840 --> 01:15:15,840
believe it was for about a
Canadian or about 800 million

1366
01:15:15,840 --> 01:15:20,120
Aussie, I think something like
that and not too much cash

1367
01:15:20,120 --> 01:15:22,120
flows.
And now sort of parting ways

1368
01:15:22,120 --> 01:15:24,240
with it.
I think their market cap at the

1369
01:15:24,240 --> 01:15:29,000
time of acquiring that asset was
sort of in the mid ones to maybe

1370
01:15:29,000 --> 01:15:34,040
load, you know, load 2 billions.
Now it's sort of 300 mil market

1371
01:15:34,040 --> 01:15:36,520
cap.
And we'd, you know, a lot's

1372
01:15:36,520 --> 01:15:39,960
changed since back then.
They've had a bit of a tough

1373
01:15:39,960 --> 01:15:45,120
time the last few months.
So you know, sort of November

1374
01:15:45,120 --> 01:15:48,760
when they sort of raised money
and announced that Simbiri

1375
01:15:48,760 --> 01:15:50,120
expansion.
They were sort of trading in the

1376
01:15:50,120 --> 01:15:54,320
mid 40s, then to the low 30s,
then fell again to the mid 20s

1377
01:15:54,320 --> 01:15:57,160
later in the year when they
received a, a tax assessment

1378
01:15:57,160 --> 01:16:00,360
from the PNG government on
Simbiri, which was sort of

1379
01:16:00,360 --> 01:16:04,000
claiming additional taxes and A
and a penalty in position of

1380
01:16:04,000 --> 01:16:08,240
$210 million, which they've
they've rejecting and, and

1381
01:16:08,240 --> 01:16:12,680
defending and sort of yeah,
trading in the mid 20s still

1382
01:16:12,680 --> 01:16:15,080
today.
You know, they could certainly,

1383
01:16:15,200 --> 01:16:19,480
you know, depending on what they
do with the Atlantic assets, you

1384
01:16:19,480 --> 01:16:23,560
know, use that proceeds to sort
of reinvest at Simbiri.

1385
01:16:23,560 --> 01:16:27,760
But I don't know who would, who
would buy that?

1386
01:16:27,760 --> 01:16:30,400
I'm not sure.
I'm not too familiar with, you

1387
01:16:30,400 --> 01:16:34,160
know, they're saying, you know,
a Canadian company summing up

1388
01:16:34,160 --> 01:16:37,040
that way should be, you know,
the natural hold of those

1389
01:16:37,040 --> 01:16:38,560
assets.
I'm not too familiar with that

1390
01:16:38,560 --> 01:16:39,960
part of the world.
So good luck to them.

1391
01:16:40,160 --> 01:16:42,840
Yeah.
So interesting to say what

1392
01:16:42,840 --> 01:16:47,040
happens with that one.
And to finish on a bit of a

1393
01:16:47,080 --> 01:16:49,400
shell.
Yeah, could be a shell too.

1394
01:16:49,600 --> 01:16:52,240
Right, but it might be into an
ASX shell, who knows?

1395
01:16:52,640 --> 01:16:55,080
So we, yeah, literally, who
knows?

1396
01:16:55,080 --> 01:17:00,200
So we'll we'll keep following
that one and to finish on a bit

1397
01:17:00,200 --> 01:17:03,920
of a a bit of a fun note.
We've had there's been a few

1398
01:17:03,920 --> 01:17:09,160
small cap gold explorer bolters
this month.

1399
01:17:09,600 --> 01:17:14,040
You know, all pretty early stage
stuff from from a few minnows

1400
01:17:14,040 --> 01:17:17,360
around this sort of West
Australian, you know, gold space

1401
01:17:18,040 --> 01:17:21,640
in the last week or so.
But that have, you know, they've

1402
01:17:21,640 --> 01:17:24,360
put some, you know, essay
results and got cops and, you

1403
01:17:24,360 --> 01:17:26,600
know, pretty huge share price
reactions so.

1404
01:17:26,800 --> 01:17:28,240
Wait, go, go take us through
them.

1405
01:17:28,240 --> 01:17:31,920
This excites me, this stuff.
Yeah, so which is, you know, in

1406
01:17:32,120 --> 01:17:38,160
a what do we have 4600 odd buck
an ounce Aussie gold price

1407
01:17:38,160 --> 01:17:39,800
environment, It's pretty
exciting stuff.

1408
01:17:39,800 --> 01:17:45,040
So, So what happened?
So Ozorim a couple weeks ago

1409
01:17:45,040 --> 01:17:49,600
recorded reported some aircore
results at their Mull Gabby N

1410
01:17:49,600 --> 01:17:52,600
Gold project.
One of the hits was 20 metres at

1411
01:17:52,600 --> 01:17:57,920
3.57g a tonne from surface.
They were up over, you know,

1412
01:17:57,920 --> 01:18:01,040
since they announced so over
400% off the back of that

1413
01:18:01,040 --> 01:18:04,200
result.
And you can see here on on a map

1414
01:18:04,200 --> 01:18:06,680
from one of their announcements
that they're pretty close to

1415
01:18:07,040 --> 01:18:10,640
Northern Stars, Kara Sudan and
Ramirez's sort of Rebecca Rowe

1416
01:18:11,120 --> 01:18:13,840
project.
Another one sort of few days

1417
01:18:13,840 --> 01:18:16,480
later on the 7th of Feb,
Kalgoorlie Gold Mining reported

1418
01:18:16,480 --> 01:18:19,960
some air core drill results at
their pingin, which is now

1419
01:18:19,960 --> 01:18:22,160
they're calling Light Horse
prospect.

1420
01:18:22,720 --> 01:18:27,240
One of the hits was 17 metres at
4.8g per tonne gold from 48

1421
01:18:27,240 --> 01:18:30,600
metres similar.
You know they had a similar

1422
01:18:30,600 --> 01:18:34,560
share price reaction up over
330% since those results.

1423
01:18:34,640 --> 01:18:36,760
Our Daya resources are a
shareholder of that.

1424
01:18:36,760 --> 01:18:39,600
I think they sub close to 5% the
nickel produces.

1425
01:18:39,600 --> 01:18:40,960
Like, oh, there you go, I've
been out.

1426
01:18:41,000 --> 01:18:44,760
Of this than the bloody nickel?
And yeah, so they're, they're

1427
01:18:44,760 --> 01:18:50,080
apparently 222 kilometres
northwest of Ramirez's Rebecca

1428
01:18:50,080 --> 01:18:52,800
Rd. project.
And then they're also 30

1429
01:18:52,960 --> 01:18:57,800
kilometres from Ozorum, which we
just talked about now as well.

1430
01:18:58,000 --> 01:19:00,440
The Northern Star and Ramirez
would be like oh geez.

1431
01:19:00,480 --> 01:19:01,640
What?
What's going on here?

1432
01:19:01,760 --> 01:19:02,560
Yeah.
Yeah.

1433
01:19:03,320 --> 01:19:06,520
And and then finally Caprice,
which is a.

1434
01:19:06,520 --> 01:19:08,880
Ding, Ding, Ding today, ping.
Some up white.

1435
01:19:09,280 --> 01:19:12,560
Bloody.
And that was yeah, today.

1436
01:19:12,560 --> 01:19:16,680
So they reported some RC essay
results from their Ireland

1437
01:19:16,680 --> 01:19:18,600
projects.
So one of their hits was 28

1438
01:19:18,600 --> 01:19:25,440
metres at 6.4g per tonne gold
from 114 metres though up over

1439
01:19:25,440 --> 01:19:29,200
100 and something percent today.
And they're very, very close to

1440
01:19:29,920 --> 01:19:34,480
Remelius's break of day project.
You can see on one of their maps

1441
01:19:34,480 --> 01:19:36,280
from the announcements.
Yeah.

1442
01:19:36,600 --> 01:19:39,280
Maybe Remelius won't need to buy
Karasudam or anything.

1443
01:19:39,520 --> 01:19:40,880
Oh yeah, that's why I was quite
funny.

1444
01:19:40,880 --> 01:19:43,360
I was like, oh geez, they're all
like all these three in the last

1445
01:19:43,360 --> 01:19:47,760
sort of week and a half all seem
to be around Remelius's asset.

1446
01:19:47,760 --> 01:19:50,280
So, you know, if Spartan doesn't
work out, you know, they might

1447
01:19:50,280 --> 01:19:54,240
have some early stage prospects
in the pipeline, but there's.

1448
01:19:54,240 --> 01:19:55,960
A couple of other ones too,
Jason.

1449
01:19:55,960 --> 01:19:59,280
Yeah, oh God, I'm sure there's
plenty, but I know it's.

1450
01:19:59,280 --> 01:20:01,240
Great.
When they've gone up to 100%

1451
01:20:01,280 --> 01:20:03,040
I'll be proud.
Ding, Ding, Ding.

1452
01:20:03,480 --> 01:20:07,040
I love it, but no, it's great
to, you know, obviously all this

1453
01:20:07,040 --> 01:20:09,560
is pretty early stage stuff, but
it's, it's great to see some,

1454
01:20:09,600 --> 01:20:13,200
some positive activity sort of
heading down into the, you know,

1455
01:20:13,200 --> 01:20:17,520
the early stage explorer curve
of the development cycle in, in

1456
01:20:17,520 --> 01:20:18,600
WA.
So it's awesome.

1457
01:20:18,760 --> 01:20:21,160
How good is it?
Oh, that was a bloody marathon.

1458
01:20:21,160 --> 01:20:25,040
I think I waffled on with
absolute shit, but it's just, I

1459
01:20:25,040 --> 01:20:27,600
get so excited and it's like
underground lighting.

1460
01:20:27,840 --> 01:20:29,240
I love it.
I just love it.

1461
01:20:29,560 --> 01:20:31,640
Oh, and I'm sure the money
miners would have loved it as

1462
01:20:31,640 --> 01:20:34,200
well.
