The platinum-palladium mineralization was associated with the sulfides which made up about 1 pct of the rock. Microscopic examination of screened fractions of crushed ore showed that most of the sulfides could be liberated at 200 mesh. The Bond Index value for grinding the ore to minus 200 mesh was 16 kW·h/ton. Specific gravity of the ore was 2.8.
