Musgrave Minerals Ltd (ASX:MGV, OTC:MGVMF) has revealed gold recoveries between 93% and 99% in metallurgical test work on samples from the White Heat-Mosaic and Big Sky deposits, prospects of the Cue Gold Project the company recently secured mining leases over.
MGV completed a number of tests with different recovery rates, including:
- conventional gravity and cyanide leach tests with fast leach kinetics: 93%-99%; and
- gravity only tests: greater than 36% recovery in oxide at Big Sky and greater than 76% in fresh rock from White Heat-Mosaic.
“Positive step forward for the project”
“This is another set of strong, consistent metallurgical results which show there is a general uniformity and consistency with the recoveries across all our gold deposits at Cue,” Musgrave Minerals managing director Rob Waugh said.
“The very high total gold recovery and high gravity-only component recovery ensures that conventional processing options can be applied in any development scenario moving forward and will strongly inform the Stage 1 PFS, which is due for completion late in the first quarter CY2023.
“The metallurgical recoveries are consistent with those previously observed from the Break of Day and Lena deposits."
“In addition, two new mining leases have been granted and now include full coverage of the Big Sky and White Heat-Mosaic deposits.
“Our granted mining leases now fully encapsulate all our gold resources in this area, and cover the broader development envelope. This is another significant positive step forward for the project.”
Musgrave has also completed a follow-up reverse circulation (RC) drilling program at the Waratah and Amarillo prospects as well as new regional targets, with results expected mid-to-late January.
