West Australian focused gold exploration and development company Rox Resources (ASX:RXL) has produced promising metallurgical testing results on ore from its Youanmi Gold Project.
Based on using a pressure oxidisation leaching process, Rox testing showed a potential recovery rate of about 96 per cent from core samples taken from Youanmi Deeps. Historically, the Youanmi Gold Project operated on a recovery percentage of 86.8 per cent.
The metallurgical testwork forms part of development studies currently underway into future production at the Youanmi Gold Project. This preliminary part of the study will establish processing pathways to optimise gold recovery prior to progressing to more extensive and detailed “feasibility study level” metallurgical testwork.
Rox Resources Managing Director Alex Passmore commented:
“In June we reported a 30% increase in the Youanmi Deeps Resource, and now we are pleased to report that advances in gold extraction technology over the last 30 years (since GMA built its processing plant) have made a significant difference in gold recovery.
“Preliminary metallurgical testwork indicates a 10% increase on historical gold recoveries by utilising a pressure oxidation leach process.”
