CONT

Ore grades are somewhat variable. The lowest grade of working deposit in western countries appears to be at Outukumpu (Finnish) mine working 0.2% Ni ore. This low grade can be compared with the very high grade sections of some Western Australian deposits that run about 12% Ni. Of course, the overall grade for Australian deposits is less than this because lower grade ore is mined with these high grades.

CONT

CONT

The gold zones contained as much as 30% disseminated sulphides, but high gold values appear to have been independent of base metals.
