Revolver Resources Holdings Limited (ASX: RRR) has announced strong initial outcomes from heap leach process test work undertaken for its Dianne Copper Mine Project located in north-west Queensland.
Managing director, Pat Williams, commented, “We are extremely pleased with the initial outcomes from the process and column leach testwork undertaken to date on various samples from the Dianne Deposit. To be on track to achieve our target recoveries and residence times in a standard leach environment, and then surpass them in an enhanced setting, is a strong validation of the technical and economic opportunity afforded to us by the Dianne Copper Mine Project.”
Key outcomes include relatively low abrasion indices delivering low plant wear dynamics, low fines content (only 5 – 10% < 150µm) sees readily amenability to heap leach, and relatively low acid consumption (10 – 15kg/t) compared to other Australian heap leach operations (typically 20 – 40kg/t.
Further, both oxide and transition material are on track to achieve the targeted +85% recovery within the 6 – 9 months residence timeframe, and both material types also responded well to enhanced leach conditions, achieving or exceeding target +85% recovery with 4 – 5 months residence timeframe.
The company expects column leach testwork to conclude during Q4 2024, with results finalized in Q1 2025.
