White Dam’s associated copper concentrate production from a sulphidisation-acidification-recycling-thickening (SART) plant continues to ramp up in line with expectations, GBM said.
The JV has also identified further optimisation opportunities, which is expected to drive “expanded production” and reduce costs at White Dam.
The White Dam gold mine is located in South Australia, 80km west of Broken Hill.
It commenced operations in 2009 and has since produced more than 170,000 ounces (oz) of gold from 7.3 million tonnes (Mt) of ore that were mined from its two open pits.
GBM Resources managing director and CEO Peter Rohner said: “While recent rain has resulted in some minor delays, the additional water is set to drive increased heap leach irrigation and thus higher gold and copper production in the near term.
“We are now working to finalise shipping of the first copper concentrates once the concentrate drying process is completed.
“The SART Plant is meeting its design objectives of removing copper and increasing the recovery of the cyanide solution back into the circuit to increase gold recoveries, which together enhance the overall economics of the White Dam operation.”
