De Grey Mining (DEG) will commence a pre-feasibility study (PFS) for its Mallina gold project in WA’s Pilbara region after completing a scoping study.
De Grey Managing Director and CEO Glenn Jardine said the scoping study provided justification the project was viable.
“The PFS will immediately commence in parallel with ongoing resource extension and definition drilling, exploration activities and further metallurgical testwork. The results of the PFS are expected to be provided in the second half of calendar year 2022,” Mr Jardine said.
The study projects an average production of 473,000 ounces of gold per annum over the first five years, which the company said would make Mallina a top-five Australian gold mine based on average annual output.
Over a 10-year evaluation period, Mallina would have an average output of 427,000 ounces with the Hemi deposits comprising 80 per cent of this production.
The study is based on the global mineral resource for Mallina which was released in June and sits at 230 million tonnes at 1.2 grams of gold per tonne (g/t) for nine million ounces.
Since then, De Grey has extended mineralisation at Diucon and Eagle prospects. The company also expects to optimise project metrics further by boosting the global resource.
