Alternatively, most discussions have been revolving around cobalt operations, why don't I start with some copper discussion then.

I was directed to Tschudi copper mine which is located SE of Opuwo:

Although the BFS for the project came out in late 2012, I believe we can get some estimate on it's cash cost for Copper & maybe for capex as well. https://www2.trustnet.com/Investments/ArticlePrint.aspx?id=201212190700078555T

It quoted a LOM capex of ~109m USD which was for 2.6mtpa plant with 17ktpa SX/EW facility. So half of that is USD58.5m for 1.3mtpa + 8.5ktpa copper plant. I don't know how expensive are cobalt processing plant but I am assuming a USD100m which put total capex of approx USD150m would be the minimum capex for a 1mtpa start for CLA? If that's the case, which I think we are, really shows how good an investment CLA is.

Of course, this is my amateur guesstimate so please criticise it as much as you can because I am here to learn from much educated posted we have here.
