if you do a bit of googling you can see that similar deposits have been mined before. Not pretending it would be easy and you would get a fair bit of dilution, hence the plant would need to be significant $$$$$$. The potential would be to secure the oxidised zone rights, mine that to generate funds to enable deeper mining.
Agree that this would be a good fit for Chalice, surprised they are not grabbing it for cash, as I am sure the announcements on securing millions of ounces of PGM would increase the share price more than the cost.
