Hi Canary
Is this the post you wanted to see
ā The Western Front zone 1 is where the first production will come from.
They are targeting a 70m deep zone split into 2 levels of about 30m.
The top 30m contains the first section of HAD005 one of our best holes.
Thereās some phenomenal gold and copper grades
within it.
Gold grades above 10g/t
11.23
64.1
32
103
211
12
Copper grades over 4%
10.42%
5.4%
8.5%
4%
5.3%
4.1%
You can see the high % of copper suggesting Chalcopyrites and bornites are present.
Chalcopyrites have a specific gravity of c4.1
In the first stoping tunnel targeting this high grade ore it could be 100 metres long x 15m x 30m high in total .
Volume is roughly = 45,000 cubic metres
Multiplied by a normal sg of rock = 45k x 3 = 135,000 ton
If Chalcopyrites then Multiply with an sg of 4.1 = 184,500 ton
For a specific gravity of 3 scenario:-
If we say an average of 5g/t x 135,000 = 675,000 ā¢/ā¢31.1 = 21,705 gold ounces
For a sg of 4.1 scenario:-
Or 5g/t x 184,500 = 922,500 ā¢/⢠31.1 = 29,662 ounces
Therefore there is an increase of 50,000ton of ore if thereās Chalcopyrites insitu
Thereās around 7,400 ton of copper using the 4.1 sg which is 2,000 ton more than a 3sg.
Revenues for 30% ownership :-
Gold say average 25,000oz x $1800 = $45m x by 30% =$13.5m
Copper say average 6,500ton
6500 x $8,000 = $52m x30% = $ 15.6m
= c$29.1m revenue less costs
Ggp costs :-
Capex
SLOS operation $73m from top of ore
9 zones is around $8m per zone
Western front zone 1 has 2 levels =$4m each capex
Plus extraction costs
Transport out is at its shortest so probably the lowest AISC costs of the whole mine, Iām estimating $100-150 due to the high grades of both gold and copper but processing costs could be high with these high grade sulphides.
$643 per oz AISC will be too high for this first zone with the high level of copper.
I would assume therefore a level of $500 oz AISC is probably reasonable in the first stopes.
Thatās $300,000 per metre revenue in the first stope to Ggp
