Discovery Metals moves to final testing

Bio-oxidation (bio-ox) processing has shown the most promising results to date of a range of processing techniques being tried as part of an ongoing scoping study of Dikoloti, Discovery said in a statement. The project aims to define a cost-effective method for processing Dikoloti's nickel mineralisation.

Initial tests on the Dikoloti nickel sulphide mineralisation indicated that high nickel extractions could potentially be achieved using a bacterial leaching process.
A column test, simulating the heap-leach bacterial process, has achieved 50 percent nickel extraction to date with the nickel extraction now accelerating rapidly, suggesting that a final high nickel extraction value could be obtained at the conclusion of the test, the company explained.
