Overall, 84% of the pentlandite is pure, free, or liberated, with the best liberation observed in the -25 microns fraction at 91%. This is identified by the pentlandite exposure data where 80% of the pentlandite is exposed and the best exposure is in the - 25 microns fraction to 86%. Locked pentlandite is present in trace amounts in all size fractions. The amount of locked sulphide Ni decreased with the successively finer size fractions to 0.2% locked in the -25 µm fraction. In the coarsest size fraction, 44% of the Ni-S was exposed. A visual representation of these particles grouped by liberation class is also presented in Appendix G. As with the chalcopyrite, much of the pentlandite is liberated and is chiefly associated with pyrrhotite or other complex particles. Regrinding will likely be necessary in order to fully liberate the nickel. In the coarser fractions, there is also some association with sulphide complexes and serpentine and chlorite gangue.
