Ann: Gold Extraction Tests from Bulk Samples Recover Gold Buttons, page-71

They're all Platinum Group Metals. The six platinum-group metals are ruthenium, rhodium, palladium, osmium, iridium, and platinum. I don't think there's any REE worth worrying about - I did incorrectly use the term REE previously.

Gold is the most valuable metal in our gabbro deposits grade-wise so the extraction method should be optimised for maximum gold extraction though of course they'll recover plenty of silver and PGMs as well. Rhodium's worth more than gold lately which is nice but we'll make more money from the Pt and Pd content (and Ag). The pilot plant results will be authoritative and I'm sure they will surprise a few people.
