Palladium, iridium, and gold in the ores and host rocks of

The total precious metal tenor of typical Western Australian nickel sulfide ore is similar to that of average Sudbury ore although gold, ruthenium, iridium, and osmium are higher (and platinum may be lower) in the Western Australian ores. Both palladium and platinum are distinctly lower than in average ore from the Merensky Reef.
