Sperrylite

The original locality where Sperrylite was first identified is the Vermilion Mine, Denison Township, Sudbury District, Ontario. This famous locality still produces small lustrous crystals in the old mine dumps. Another well-known Sperrylite deposit in the Sudbury District is the Broken Hammer Deposit, Wisner Township, which produces crystals in very sharp form.

The largest and best-formed Sperrylite crystals come from the Talnakh deposit, near Noril'sk, Eastern-Siberian Region, Russia. Sperrylite is of economic value and mined for its platinum content at the Bushveld Complex, Limpopo Province, South Africa. In the U.S., waterworn crystals were found in alluvial placer deposits at Mason Mountain, Macon County, North Carolina.
