Great Boulder Resources (ASX:GBR) Reports Excellent Gold Recoveries from Mulga Bill
Great Boulder Resources has achieved remarkable results from metallurgical test-work on samples from its flagship Side Well Gold Project. The tests, conducted by Independent Metallurgical Operations Ltd, confirmed gold recoveries of up to 98.7% with low cyanide-soluble copper levels, underscoring the project’s viability.
Test Results
The test work included gravity recovery and cyanide leach testing of various ore types from Mulga Bill. Four out of five sample parcels showed high gold recoveries, with an average total recovery of 97.5% after 48 hours. The low levels of cyanide-soluble copper across the samples indicate that copper will not impact gold recovery rates or the overall processing method.
Managing Director Andrew Paterson expressed enthusiasm about the findings, stating, “This is a fantastic result for the Side Well Project and for Great Boulder shareholders. The results of our metallurgical test-work demonstrate that Mulga Bill leached extremely effectively and is therefore amenable to standard cyanide leaching. This means it can be processed through a conventional gold plant or any of the existing gold plants in the Meekatharra region.”
Implications for Future Development
Paterson noted the significance of the results in relation to potential mine development. “This is a hugely important outcome, as it removes one of the last remaining questions around potential mine development at Side Well. Mulga Bill has the majority of gold ounces known to date; it will always be the engine room of any mining operation here.” Full details of the test results and methodologies are available from Great Boulder Resources.
