i am only questioning rather than criticizing CFE because I don't know much about cobalt & was doing by best to research CFE yesterday
as for the Chinese, they are probably more interested in supply than profit (similar to Adani in Australia). the Chinese will make their profit from refining cobalt into metal rather than mining & producing Congo concentrates
imo
my point is TGS costed a 1ktpa cobalt hydroxide plant at US$22M therefore for CFE to create a plant equivalent to their current 4ktpa plant must costs lots of money; thus looking for Chinese money
