TID BITSNo one noticed ? I used a higher gram value for ( pl, pd )
Why ?
Because in 2012 they used a better acid assay
Resulting better grades
- 2012 ( sgs ) better assays
- also Lee's better assays ( reassaying historicals and new holes )
better assays revealed the exotics
Fast forward...
Juniors reverted to 4 part ( partial digest )
Look - ( #1 = sulphides #3 peridotite grades )
https://live.staticflickr.com/65535/53314406722_f0c05143da_z.jpg #1 Sulphide -
Pt 1.29/g
Pd 0.86/g
#3 Peridotite -
Pt 0.41/g
Pd 0.60/g
Another way to calc wellgreen's - pl, pd ? Using 2023 grades ( ugh )
437 million tonnes
x .26/g
=
113,620,000 million grams
~ 31.1 ( ounce conversion )
= 3,653,376 oz ( double up to arrive at approx - pl, pd ounces ) x 2
= 7,306, 752 oz comb ( rough ) Back in 2015 ( they gave approx figures on the 846 m tonne inferred category ) The Mineral Resource Estimate further consists of 846 million tonnes at 1.57 g/t Pt Eq. or 0.41% Ni Eq. at a 0.57 g/t Pt Eq. cut-off or 0.15% Ni Eq. cut-off in a pit constrained resource containing 13.8 million ounces of 3E (platinum+palladium+gold) https://www.nickelcreekplatinum.com/investors/news-releases/press-release-details/2015/Wellgreen-Platinum-Announces-Positive-Preliminary-Economic-Assessment-Update-on-its-Wellgreen-PGM-Nickel-Project/default.aspx
2015
inferred figures
were separate from the ( m + i ) 329 million tonnes
---------------------------------------------------------------------------------------
When nickel creek took the helm, later in 2015
SNC = source nickel creek ( bottom of middle chart left side )
we can see how the ( m + i ) and ( inferred ) were whittled down in size
- zone change ? lol
- upper / lower only one 1/2 of hole calc ? lol
- waste category suddenly is seen
- who decided to change the m + i of 2014 stats ?
Those 2014 stats were also used in, 2015's resource measurements
https://www.nickelcreekplatinum.com/investors/news-releases/press-release-details/2015/Wellgreen-Platinum-Announces-Positive-Preliminary-Economic-Assessment-Update-on-its-Wellgreen-PGM-Nickel-Project/default.aspx Early 2015 wellgreen junior - stock piling and process later
Latter 2015 new junior - turned lots of ore to waste
I can't help but think,
There's a high grade core ore body which ranges 200 - 300 million tonnes
Involves the UG mine ( and feeder sulphide dykes ) that bleed into peridotites
Rezone - excluded UG mine deeper zones ?
If at all accurate= erases much of the high grade tonnage and deep zones
Now recheck the 2014 vs 2015 charts and ask...
Why did latter 2015 reduce significant tonnage ?
Ah, ha...
1250 x 500m wide x
250m deep x 2.7 ore weight
=
421,875, 000 m tonnes ( very close to 2023 pfs tonnage )
If one happened to forget sending a few key ( deep intercept drill holes to eng firm
= what would it do to the deposit continuity ?
= size of deposit ?
= how about bumping up the cut off - x ing out significant silicates with plats
because one justified low grade nickel but didmissed an Eq value ?
Issue ?
Wellgreen has several 500m to 700+ meter intercepts
From mine to central zone = 1250m long
Backside of mine ( north side of mountain ( also ) I also wonder if,
eng firm ran with former eng firms recoveries.
One eng firm plots recovery grades into each block model
Second eng firm uses these figures thinking it grades and doubles up
on the revovery %'s.....
might explain the 2023 pfs metal payables
near 1/4 recovery 75% loss
Cheers.....
