7.6 Minerals
Table 7-2, Table 7-3, and Table 7-4 after Cabri et al. (1993) list the opaque minerals and PGM-
bearing minerals found in the deposit. The elevated presence of rhodium, iridium, osmium,rhenium, and ruthenium within the mineral suite provide an opportunity for additional potential economic contributions from these metals.
Rhodium is present on the Project in highly anomalous concentrations as compared to the concentrations found in Noril’sk ores in Russia and other significant ultramafic systems globally (Hulbert 1997).

$135.03 Rhodium Price per Ounce
$4,200.00 Rhodium price per kilo
$135,033.14 Lab ppm once converted
results in grams per tonne
Here's a pdf on Russia's Oktyabr'sk area ( famous Norilsk ) ** notice values are in ppb
versus
wellgreen is in ppm ( better grades )

https://www.uqac.ca/sjbarnes/publications/zientke-94-norilsk.pdf As for Wellgreen's deposit ?
What is irons listed as major metals ?
Yes... 2 kinds
Magnetite Fe3O4
Ilmenite FeTiO3 imagine applying a 2 phase magnetic flowsheet roasting ores ? 30% - 40% PGE's are clinging to magnetite
Then, once heated to demagnetized = float and froth
IImenite It is the principal ore of titanium. It is black (or dark gray) and has a metallic luster. It is usually weakly magnetic. The mineral itself is actually not magnetic, but it is often intergrown with magnetite, which very strongly responds to the magnetic force.
