Figure 8: Pyrrhotite Exposure
Pyrrhotite liberation (pure, free and liberated combined) in the sample is very good and accounts for 91%
of the mineral mass overall with the best liberation seen in the -25 micron fraction at 94%. This is also
noted in pyrrhotite exposure data where 87% of the pyrrhotite is exposed. In the coarsest size fraction this
decreases to 74% with the expected increase in exposure in the finer fractions to 92%. Less than 0.1% of
the overall pyrrhotite was locked.
Pyrrhotite associations exist with other sulphides and chiefly with complex gangue particles in all size
fractions.
