Ann: Drilling Confirms Discovery of Large Cu-PGE Sulphide Reefs, page-235

Hello. From this link: https://www.ivanhoemines.com/wp-content/uploads/20021platreef22fs_220311rev1_comp.pdf is a study with what looks like 3 to 4 times the TM1 grade. Per the previous diagrams, its deep underground but the mineralised ore looks relatively flat. The study is close to current prices. The total AISC (operating costs) are US$115.81 per tonne of ore with study revenue of US$223.64 per tonne of ore or at current prices $199.14 per tonne of ore.

Note: the numbers $223.64 revenue, $108.34 ($56.48 + $51.86) operating costs and $115.30 margin per tonne are straight from the study; as is the $28 billion in total revenue.
