Altamira Gold CEO Michael Bennett joined Steve Darling from Proactive with results from an internal metallurgical leach characterisation test on a drill core from its Cajueiro project in Brazil.

Bennett tells Proactive the testing used a proprietary thiosulphate leach technique developed by Clean Mining. That 24-hour test showed, at a grind size of 80% passing 75µm, recovered 92% of total gold content. The testing shows the potential for a non-cyanide process route on the project.
