60% is ok at this stage further on site processing may be able to increase this figure,
see below,
Unlike massive sulphide ores, the processing of disseminated sulphide ores has proven to be more challenging even though the ore grades of some of the worlds largest most economic deposits are often reasonable (0.6 to 0.9%). The problem has been related to processing; the conventional flotation process on low-grade disseminated sulphide ores tends to be difficult due in large part to fines containing large amounts of magnesium rich serpentine type minerals which generate slimes during comminution. In most cases treatment of such ores results in a low nickel recovery and produces a concentrate unacceptably high in magnesia.Nickel smelters typically cannot handle such concentrates without blending, due to inescapable problems with slag metallurgy. As a result nickel grade and the Fe:MgO ratio in concentrate are key parameters in order to control smelting temperatures and slag viscosity and minimize operating costs
The good news is our ore is very clean and as is stated in the report further metallurgical test work will be undertaken.
From our report,
all the best
