Earlier metallurgical take a look at work for the Windarra Tailings undertaking had proven potential enchancment in recoveries and prices for the positioning’s gold sources. The take a look at work additionally established the potential for a technical, economically viable and low-intensity course of for restoration of nickel from nickel tailings, the corporate stated.
A earlier feasibility research for the gold useful resource utilizing standard cyanidation confirmed internet working cashflow of A$30.6 million, Internet Current Worth (NPV8) of A$21.7 million and an Inner Price of Return (IRR) of fifty.6%, assuming a gold worth of A$2,500/oz ($1,629).
The following step is to undertake a technical programme to optimise the undertaking with each the gold and nickel sources, which is able to result in an up to date feasibility research and a closing funding determination. If profitable, the undertaking will result in the development of the primary GLT processing plant for tailings.
“We’re excited to play an integral position in enabling the retreatment of the gold and nickel tailings on the Windarra Tailings Undertaking by supplying GLT, which has been developed to extract valuable and base metals,” Draslovka Mining Course of Options chief expertise officer Ivor Bryan stated in a information launch.
“GLT is revolutionary for the mining trade,” Bryan stated. “It has the potential to avoid wasting mining corporations billions of {dollars} by considerably decreasing processing prices, enhancing a mine’s sustainability profile, extending mine life by reducing the cut-off grade and unlocking worth hidden in a mine’s tailings. I imagine the outcomes at Windarra will probably be a strong instance of how GLT is an easy but very efficient means to retreat and monetise tailings.”
