Xanadu Mines (XAM) gave an update on its metallurgical test program at the Kharmagtai Copper-Gold Project in the South Gobi region of Mongolia.
Preliminary metallurgical test work was completed on partially oxidised material from surface to 30 metres depth.
Glycine and cyanide leach tests delivered metallurgical recoveries of up to 91 per cent gold and 46 per cent copper, with head grades ranging between 0.52 g/t to 2.25 g/t Au and 0.12 per cent to 0.67 per cent Cu.
All partially oxidised material leached readily at a coarse P80 greater than 2mm particle size, indicating the potential for a heap leach treatment.
The company also found a potential treatment path for 90 million tonnes of oxidized material treated as waste in the Scoping Study1 due to low flotation recovery.
This marks the first step in evaluating a material uplift opportunity, which the company had identified in its Scoping Study, to generate additional cash flow by leaching partially oxidized, near surface material.
Now the company looks to further mineralogical studies to confirm viability and optimise the process.
Xanadu’s Executive Chairman and Managing Director, Colin Moorhead called these preliminary results a very positive, first step as the company tests the uplift opportunities in the Kharmagtai Scoping Study.
“The base case assumed that all ore is processed through a standard sulphide circuit, which means that the partially oxidized material at the surface, which does not float, ends up being treated as zero value waste. If we can turn that material into cash generating ore by leaching with glycine and cyanide, it has potential to drive significant value uplift for the Kharmagtai project.”
