THE DRILL SERGEANT: Corazon Mining (ASX: CZN) has completed metallurgical testwork at the company’s Mount Gilmore cobalt-copper-gold project in New South Wales.
Corazon Mining said the Phase 3 metallurgical testwork at the Mount Gilmore project delivered a high-grade cobalt concentrate with the potential to supply the emerging global battery technology sector.
The company explained the Phase 3 metallurgical testwork focused on defining down-stream concentrate processing options, the results from which demonstrated exceptional recovery rates of cobalt, copper and gold from drill samples from the Cobalt Ridge deposit, using conventional processing routes.
Conventional flotation testwork delivered a high-grade cobalt-copper-gold concentrate – of up to 7.38 per cent cobalt – from high-grade Cobalt Ridge samples, as well as excellent concentrate grades from lower low-grade samples.
Corazon said the combination of high-grade concentrates and very high recoveries delivered in the testwork provides it with the opportunity to potentially either produce a high-value bulk concentrate for direct sale, or to develop an in-house down-stream processing plant.
“The mineralisation at Cobalt Ridge has several beneficial characteristics,” Corazon Mining said in its ASX announcement.
“A key advantage for the processing is the sulphide mineralisation, which allows for a smaller sulphide/metal concentrate to be produced prior to down-stream processing.
“This would likely significantly reduce the capital and operating costs of a down-stream plant, compared to having to process a bulk feed.
“The company has continued to undertake systematic testwork programs on mineralisation from the Mt Gilmore project in parallel with its ongoing exploration activities.
“The testwork programs are designed to confirm the suitability of the project’s mineralisation to produce a high-quality product(s) for use in the battery technology sector.”
