This announcement from FCC prompts me to ask - what is a good Co grade?  I am not a miner, so have to rely on others.

Cobalt Institute says 0.1 to 0.3% is typical for sediment hosted ores.

Or, we can look at rival eCobalt's resource, which grades 0.59%

The eCobalt project appears to be an underground mine, while FCC's looks likely an open cut, with the resource coming to surface. Open cut is cheaper and extracts all ore, though at these grades FCC will be moving a lot of dirt. 

Cu is also present, though likely only enough to reduce the processing cost. 

If any miners on HC can enlarge on this broad-brush, I would be grateful.
