2015 PERSPECTIVE2015 diagram showing 3 pit phases Phase 1 - yellow - PEA Base Case 25 mine yrs
Phase 2 - Red - pits dug deeper
Phase 3 - outlier perimeter ( aqua ) 30+
extra mine yrs 2015 -
majority sulphide + gabbs 2015 - Yellow PEA Zone 3200m L ( east to west )
900m W ( N to S ) though wider, i used 900m to sq the pit constraint
200m D
2.7 ore weight
=
1,555,200,000 billion tonnes What About ? What about all the ore below 200m ? ( 350m - 500m - 676m near UG mine )
What about entirety of UG mine ?
What about ore below 0.20% eq grade cut off - 2015 used 0.15% eq
What about silicates harboring other minerals, cr, ti etc...
Spatial ? I'm seeing well defined zones
- carved zig zags everywhere - outlining - sulphide surface veining ?
- small pits / white patches exposed ground
2015 PEA Yellow Zone
only factored sulphides + gabbs with only 10% peridotite - 25 yrs
329 M tonnes
846 M tonnes inferred
5th stage aqua colored perimeter is massive
includes portion of, what i call
sulphide mountain 5th phase pit only factored 25% peridotite ( 3 geos )
which means = 75% remaining = sulphide + gabbs
The 5th phase pit added an extra 30+ mine years
Tonnage would be staggering.
-------------------------------------------------------------------------
How would 2015 crew estimate 846 M tonnes inferred inside yellow zone ? Could the exposed surface zig zags etc... with field chip samples
have allowed this inferred estimation ?
How about older drills...
Hudbay, Chevron, Corronation, All North, Indigenous drilling, Archer geo services ?

CIM STANDARDS
An Inferred Mineral Resource is based on limited information and sampling gathered through appropriate sampling techniques from locations such as outcrops, trenches, pits,
workings and drill holes.May 10, 2014
https://mrmr.cim.org/media/1128/cim-definition-standards_2014.pdf Anyone seeing
distant zig zag trenching away from drill holes ?
Any pits ?
Lots.
-------------------------------------------------------------------------
I added - yellow line and dot - quill zone + base camp
As most know by now...
I prefer the 2015 PEA
Park the 2015 PEA ( sulphies, gabbs, 10% perido ) on the sidelines
Pull forward phase 2 and ask, - were upper cores ( silicates ) sent for phase 2 ?
- how do cores from middle zone represent entire deposit ?
- 2015 bulk con high recoveries vs 2023 pfs 25% metal payables ? ( approx )
- was 25% recovery also applied to 2015 - 329 m tonnes ?
- or... was 2023 pfs only factoring 437 m tonnes silicates and 329 m tonnes not included ?
- why does 2023 pit not cross the valley like 2015 ?
- why up the
eq cutoffs cancelling 86% of inferred ?
- silicates are well mineralized
Pit Comparisons https://live.staticflickr.com/65535/53332579664_d60f7e4652_z.jpg Images showing deep mineralization ( very deep )
WS 271 = 676m core mineralization
WS 188 = 457m - 2023 pit goes nowhere near this depth ( blue pit )

trency, pits, outcrops for inferred resources.
