THE DRILL SERGEANT: Galena Mining (ASX: G1A) has completed Pre-Feasibility Study (PFS) metallurgical test-work at the company’s 100 per cent-owned Abra lead project in Western Australia.
Galena Mining said completion of the final locked-cycle processing stages delivered further excellent metallurgical results, confirming very high metal recoveries in a high-grade and clean lead-silver concentrate.
Results exceeded both the company’s expectations and what had been modelled in internal Scoping Study test-work.
Composite samples delivered lead concentrate grades ranging from 69 per cent to 81 per cent (averaging 74.5%) with recoveries between 94 per cent and 96 per cent (averaging 95%).
Galena indicated that the very high lead grades in concentrate achieved by the PFS will aloow the company to increase metallurgical recoveries above 96 per cent if desired while still maintaining an extremely high lead-in-concentrate product.
“This is the most comprehensive level of process metallurgy completed on Abra to date,” Galena Mining COO, and PFS manager Troy Flannery said in the company’s announcement to the Australian Securities Exchange.
“The results not only confirm but exceed positive results from previous work.
“The exceptionally high-grade and clean lead-silver concentrate achieved at very high recovery grades gives Galena great flexibility in optimising throughput and capital cost components of the PFS which is currently underway.
“These results should be viewed as having de-risked the metallurgy component of the current economic study at Abra.
“The finalisation of metallurgy work now paves the way for GR Engineering to complete their work which is already highly advanced on plant and site layout.”
