"I'm assuming COB technology does not allow for the copper by product?"
@tally49
Havilah's ASX Media Release (see PDF below, page 2) on 21 June 2018 said:
"The copper in the sulphide ore was recovered [via COB's proprietary cobalt recovery processing methodology] as a separate clean copper concentrate (copper grade of ~29%) and the preliminary testwork showed that only 2.7% of the cobalt reports to the copper concentrate. Recoveries of copper can be optimised by using finer milling sizes of the ore prior to magnetic separation of the pyrrhotite fraction, as determined by previous Havilah testwork.
No attempt to recover gold was undertaken during the current test program."
Cheers
