ASX-listed WA gold miner Wiluna Mining has pumped out a solid 12 months of gold production at its Wiluna operation about 530km north of Kalgoorlie in the state’s prolific north-eastern Goldfields with the performance bolstered by a cracking average price on gold sales. Wiluna has its eyes firmly on a steadily progressing “stage one” expansion program at Wiluna.
It involves the mine transforming from the current processing of free milling ore via an existing 2.1 million-tonnes-per-annum conventional CIP plant to treating sulphide ore through a 750,000 tonnes per annum-capacity flotation concentrator that is under construction. The company sees the fully developed stage one project more than doubling Wiluna’s gold production level to about 120,000 ounces per annum in concentrates from underground mining of about 750,000 tonnes of sulphide ore a year. Management says construction of the concentrator that underpins stage one is about two-thirds complete and underground mine development is well advanced.
The company is looking at commissioning the concentrator in October this year, with a view to initial stage one production kicking off in the December 2021 quarter and ramping up to 120,000 ounces per annum by the end of the 2022 financial year.
