Altamira Gold releases metallurgical test results from drill samples at Maria Bonita Target

(via NewsDirect)

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.
