Karlawinda pours first gold
PERTH (miningweekly.com) – The Karlawinda gold project, in Western Australia, has poured its first gold.
ASX-listed Capricorn Metals on Thursday told shareholders that gold bars weighing 12 kg, or 386 oz, were poured in the first smelt on site.
“First gold production at Karlawinda is a great credit to Capricorn’s construction and operations team, who with our key contractors, have worked tirelessly to deliver this project. We will now focus our efforts on ramping up the project to full operations as efficiently as possible,” said Capricorn executive chairperson Mark Clark.
The optimisation of the three-stage crushing circuit to deliver the most suitable product size for ball mill feed in laterite ore is also continuing, with the crushing circuit running in excess of 1 000 t/h at times, during the six days of start-up operations to date.
The ball mill has achieved a throughput rate of up to 480 t/h on an ad-hoc basis during the six-day start-up period, which is encouraging, said Capricorn, as the 4.25-million tonnes a year was the budget throughput for laterite feed used in generating expected long-term throughputs of between 4.5-million and 5-million tonnes in fresh blend, and 4-million to 4.5-million tonnes a year in fresh rock.
Run-of-mine stockpiles are currently in excess of 450 000 t of ore.
The A$132-million Karlawinda was initially expected to produce 660 955 oz over an eight-and-a-half-year mine life.
