Altus Strategies Plc announced excellent results from metallurgical testwork on oxide and sulphide samples from the Company's 100 % owned Diba gold project ("Diba" or the "Project") in western Mali ("Mali"). The work was undertaken to test the amenability of Diba ores to carbon-in-leach ("CIL") and heap leach processing.

"The results of the metallurgical testwork on both oxide and sulphide material from Diba are simply excellent. Heap leach amenability shows 95.8 % gold recovery at a coarse crush size. This recovery is significantly higher than the 80 % modelled in the current PEA which we reported on in July. More significantly, the testwork on fresh (sulphide) samples shows that CIL processing will likely be very effective, with 86.8 % gold recovery at attractive grind sizes.
