2011 - 2015
resource was based on
516 ug mine holes
reassaying historicals / bores
80 above mine
70+/- west
additonal new holes
By mid 2015
329 ( m + i ) mil tonnes and 846 mil tonnes inferred
core high grade zone ( 245 mil tonnes )
high grade zone 245 mil tonnes ( bottom chart )

boundary changes
test sulphides + gabbs ( later ) yet.... these comprised 2015 resource lol
cut offs
86% resource loss
zone name changes
sold property in Ontario ( URSA )
spot prices
extraction / crystalines
recharacterize ore ( majority is now peridotite ) Sept. 7, 2017 https://www.nickelcreekplatinum.com/investors/news-releases/press-release-details/2017/Wellgreen-Platinum-Provides-2017-Drill-Program-Update/default.aspx More drilling for met tests
How can these holes represent entire deposit and Jan 22 2018 met tests ?
Simple answer ?
Sulphide and Gabbs were separate earlier in 2017.
My Take ?
Original resource ( 2011 - 2015 ) included gabbs + sulphides
2017 separated these higher grade ores
recharacterize + boundary changes + dividing deposit using upper / lower
since lower mafic high grades are aside ug mine
these lower mafics are grouped with ug mine
sulphides gabbs and (
clinopyroxine = crystaline high grade aside gabbs )
I figure the lower mafics in mine, closest to mine
= 245 mil tonnes core high grade

Why wee bit of clino ?
Here's a great triage visual ores change to majority peridotite - lol
Peridotite invades / replaces high grade clino's - lol
First 2 images same zone - Far East morphs - lol
Sum ?
Sulphide + Gabbs test later
Massive clino becomes predominate peridotite
To... 3rd image most all peridotite
= extraction = poor 2023 pfs payables
Again,
what was the foundational resource from 2011 to 2015 ?
UG mine and ores around ug mine
Even extraction tests using 80% peridotite 15% gabbs 5% sulphides
Remind oneself of, 329 mil tonnes ( m + i ) includee ug mine ( 2013 assays )
245 mil tonnes high grade with the 2015 yellow pea pishell ( sulphides, gabbs, clino )
846 mil tonnes inferred
If extraction can't handle crystaline ?
= poof clino gone peridotite replaces clino (
orange color )
= 1st image morphs to 2nd image to eventually 2023 3rd image
= 2023 most all peridotite
= can extraction handle peridotites with high Mg and course grind ? lol
= silicates need the fine grind and secondary phase to capture solid solution
Cheers..
