As pointed out in previous posts, Yukon has a
variety of copper ore geologies. Main Link to Mines in, Yukon - various copper ores https://www.mindat.org/locentries.php?m=1040&p=8188 One of the predominant kinds of copper in nearby deposits is,
Chrysocolla Looks near same color as Wellgreen's topical geology.
I will say, this aqua green coloration can also be sulphide in nature as
it can also be hydroxide and chloride.

https://live.staticflickr.com/65535/53378035794_1bfb204bb3_c.jpg Let's play suppose, suppose there were Chrysocolla copper in, Wellgreen's deposit.
Could sulphur acid extract it ? Yes... but it needs ammonia or nitric acid assistence.
Issue ? Chrysocolla in silicate crsytal developes a Gel, upon extraction
breakdown of, silicates.
Yet... in 2012 MET study, Silicates were floatble using - PAX.
Could this... spark the thought of 846 M tonnes inferred ?
And 2017, can't process crystalines ?
So... if ores were fine milled. Iron pulled
Plat group and gold pulled
Silicates pulled oul using PAX and sent to
second extraction phase what might it look like ?
= Much less material to separate nickel, copper, cobalt.
PROCESSING SILICATE COPPER In this paper, we describe a solvoleaching study of high-grade chrysocolla with an organic solvent, comprising the chelating extractant LIX 984 N or the acidic extractant Versatic Acid 10 with
tert-amyl alcohol as modifier in an aliphatic diluent, in the presence of a small volume of aqueous ammonia. The
developed process is not only selective for the recovery of copper from chrysocolla copper ore, but it is also efficient since the leaching and extraction are carried out in a single step. The
stripping with sulfuric acid or copper sulfate generates a highly concentrated solution of copper sulfate that is suitable for electrowinning.

why not target the solid solution nickel ?
Which begs... our recovery rates should be far higher for nickel,
0.33% - nickel sulphide in peridotite
0.40% - nickel solid solution
= 0.73% total nickel (
fpx nickel uses total nickel values )
Sulphur acid would pick up solid solution nickel.
Could... wellgreen resource only be
= sulphide metallic nickel ?
Assay grades using 80% peridotite composite. https://live.staticflickr.com/65535/53314406722_f0c05143da_z.jpg Market has some intelligent people... Maybe they know of the 0.40 solution nickel
+ phase 2 - 18% copper grade influx ?
Ridding of, considerable tonnage ?
Can't process crystalines or solid solution - when... it can be done ?
Partial digest ?
No exotics added ?
What if... Market won't let stock rise till junior corrects ?
I don't know.
Cheers...
