    Given the low cyanide requirements and coarse grind size Would be interesting to go one step further and see some column leach tests initiated to see if the ore would be amenable to heap leaching at even coarser grind sizes up to say P80 20mm
    Heap leaching may be a lower CAPEX and lower OPEX processing rout that CIL/CIP processing if recoveries are high enough IMHO .
