Sperrylite is a platinum arsenide mineral with the chemical formula PtAs 2 and is an opaque metallic tin white mineral which crystallizes in the isometric system with the pyrite group structure. It forms cubic, octahedral or pyritohedral crystals in addition to massive and reniform habits.

A S-rich variety of sperrylite. Originally thought to be a member of the Cobaltite Group with the formula PtAsS. Compare 'UM1973-04-AsS:IrPt' , 'UM1989-20-S:AsPt' , and UM2005-23-S:AsPt .

Sperrylite is generally associated with layered mafic-ultramafic complexes in many of the locations where it has been found. It is an important ore mineral of platinum. It is mined with nickel ores and the platinum values of the sperrylite are recovered in the ore processing and smelting operations.

Sperrylite is a rare mineral composed primarily of the precious metal platinum. Aside from native Platinum, Sperrylite is the only platinum ore of any economic importance. It forms in highly lustrous crystals that can be very well-formed, making …

Sperrylite is a platinum arsenide mineral and is an important ore of Platinum. In fact, other than native Platinum, Sperrylite is the only Platinum ore of any significance. Sperrylite is found in abundance only at Sudbury, Ontario, Canada where it is mined for its valuable Platinum content.

A rare platinum-containing species, this splendent sperrylite crystal is almost unprecedented for the locality - it is Canadian (I know, as I it got from a mine geologist), but it has the size and impact of a more common Russian crystal. The 1.2 cm …

The world’s largest specimen of silver-gray, highly lustrous sperrylite crystals. Sperrylite is a rare platinum arsenide mineral, the main ore of platinum and often found as tiny crystals. However, the crystals in this specimen measure an extraordinary 2.5 cm.

Sperrylite is a rare, but economically important mineral. Although not found in very many places around the world, and in all but one of these it is a minor constituent, sperrylite is an important ore of platinum. In fact, besides native platinum, it is the only platinum ore of any significance.

Sperrylite is a rare mineral that belongs to the platinum group of minerals. It is a sulfide mineral that is composed of platinum, arsenic, and sulfur. Sperrylite is usually found in small grains or masses in association with other platinum group minerals, …
