@Mutley8 ............."Maybe they will not bother with copper"

That comment is very uninformed, especially when in their contracts they stipulate 2.5% acid leachable COPPER!!
Do they want to pay extra for high grade, that they just put into tailings, how ridiculous.

If you bother to read a few expert papers on cobalt processing from DRC Roan sedimentary group sources, the first step is to leach out the copper (among other elements).

If you have to leach it out anyway you may as well sell it, instead of sending it to tailings. IMO the company is being smart in asking for 2.5% copper grades so they have enough to sell as copper hydroxide product.
The only problem is that the plant is only designed to run copper ore for copper hydroxide at 250k/a currently. All the cobalt leaching equipment will have to be brought in, OR IMO the plant will be run at a reduced capacity, so some of the tanks are being utilized for cobalt, instead of all being available for copper.
