Western Australian gold explorer BMG Resources has reported that metallurgical test work conducted on core samples from its Abercromby gold project in WA have confirmed its free milling status and therefore amenability to conventional carbon-in-leach (CIL) processing, with high gold recoveries achieved.
The results show high overall gold recoveries (93 to 95 per cent after 48 hours, with majority of gold leaching in first eight hours) and low residue grades. Gravity recoverable gold component was demonstrated at between 34 and 41 per cent.
The study was conducted on drill core samples representative of fresh Abercromby mineralisation and results are consistent with, and exceed those from previous, metallurgical test work undertaken at Abercromby.
BMG Managing Director Bruce McCracken said the results are in line with their expectations from high level test work undertaken previously and represent another important step in the progression of the Abercromby Gold Project.
“This second study has reinforced the highly recoverable character of Abercromby gold mineralisation using a conventional gravity/cyanidation flowsheet, and extrapolation of these results implies high gold recoveries for the entire deposit.
“Free milling ore with high gold recoveries and low reagent consumption will significantly bolster project economics at Abercromby where BMG is targeting a maiden Resource at the Capital deposit.”
