Sorry, this is 20$/t rockIt doesn't matter if you have an infinite amount of 20$/t rock. Opperating costs are going to be way too high to extract the Ni, and the idea of extracting the Fe-Cr is misleading to say the least (way too power intensive). The recoveries of thier high grade is still way too low.
If I was invested in this company, I would consider looking more into the met work and compare opperating costs (let alone CAPEX). You need to be aware that this is likely a sham, and eventually people will wise up to it once they realize it can never be economic on any scale.
