Mini Pilot Plant created a bulk concentrate.
Nickel - 6.08 %
Copper - 3.06 %
The goal is to separate the two minerals and end up with same %'s
but each mineral unto it's own concentrate.
Nickel successfully separates from copper but...
Nickel % increases in 2nd lock test = 0.43 % ?
Commercial next phase
Nickel continues to increase to 6.7 %
= 0.72% greater than initial value
Copper goes off the chart to 13.8 %
then with final commercial outcome spikes to 18 %
= nearly 15% greater than initial value.
Again,
this phase 2 process was to simply separate the two minerals.
Now... based on initial bulk con and recovery rates it would take
= approx 43 tonnes to achieve the original - Nickel - 6.08 % + Copper - 3.06 %
There's a good 10+% to 14% iron in silicates
I'm thinking - course grind inhibited true mineral percentages
Perhaps a reagent was used in lock cycle
Or... original chloride copper was over looked in silicate solution
and once sulphide acid introduced
Equipt dialed in for sulphide minerals was now able to reconize the copper
Phase 2 majority ore was from central zone. https://www.nickelcreekplatinum.com/investors/news-releases/press-release-details/2017/Wellgreen-Platinum-Provides-2017-Drill-Program-Update/default.aspx
18 % copper using 43 ore tonnes from original bulk would place the Cu grade at
= 0.418 % What mineral % are shown in 2012 ( 80% peridotite blend )

If 2012 MET revealed solution nickel - what are the odds copper chloride ?
Maybe... phase 2 MET couldn't detect the chloride copper, but...if sulphur acid was used
and it was indeed used to soften ores ( press ) equipt seeking sulphide could then detect it.

Decair + Baptise nickel deposits are similar ( to a degree ) to that of wellgreen.
Magnesium
Dunite
Peridotite

Same Ocean sediments pushing inland.
Ocean Sediment Floor Rises,
Reefs ------> stable land to mountains to sediment booking or disenimation.
FPX has very low grades.
Yet is still able to capture 90% of low grade in solution.
Pit 1 vs Pit 5 ( jagged V pit outline )
Even dunite is mineralized.
Open at depth
Johnson hole began outside pit 1 shell - dunite still mineralized
2015 - 2018 - wow.
