THOUGHTS - As mention in few posts back... i don't think Wellgreen is a science project.
Seems to be a logic to catering to different zones.
#1 -
SGS Extraction 2012 pdf reeks of, UG mine sulphide testing.
Much higher grades.
Irony = Ni ( silicate ) is revealed. ( even in chlorites )
Solid solution grades could be higher than FPX total nickel.
2012 report - ss nickel ( 0.10% - 0.30% )
Another report - 2012 assays reveal ( 0.40% in peridotites )
#2
Phase 1 extraction Wellgreen / Prophecy Years
Mix of East + West ores
upper lower holes
seen in images Includes Silicate Nickel Blend 80%
#3
Phase 2 Looks like just Central Zone
upper / lower
in effect Majority cores from just Central 1 core from west
1 core from east

Try not to think of geo zone boundary changes 2014 -2017
digest this interpretation first.
Then, factor boundary changes.
Why never revisit UG mine ? All wrapped up / Extraction MET completed for sulphides in, 2012 ?
Silicates next onscene ?
Can't process Silicates
Then, Central ?
Combine all zones ? Ummmmm ?
It's how i'm understanding the, Wellgreen.
Maybe wrong, but....please do your own DD.
That's all i've got. ( well, almost ) lol
Let another figure it out.
