Resource(M)

Primary:	Nickel, Copper
Secondary:	Cobalt
Tertiary:	PGE, Silver, Gold
Ore:	Chalcopyrite, Pentlandite, Pyrrhotite
Gangue:	Magnetite, Plagioclase
Orebody form:	STRATIFORM, PODS, LENSES, SILL-LIKE BODIES
Discovery year:	1883

Production

Operation type:	Unknown
Production size:	None
Development status:	Prospect

Geology

Host type:	Quartz Monzonite,Peridotite,Hornfels
Structure:	The Stillwater Complex Is Exposed Along The Northern Margin Of The Beartooth Uplift, One Of Several Laramide Basement-Cored Ranges That Make Up The Rocky Mountain Foreland Of South-Central Montana (Foose And Others, 1961: Kulik And Schmidt, 1988)
Tectonic:	Tectonic Setting At Time Of Emplacement Of The Stillwater Complex Is Unknown. The Complex Was Emplaced Shortly After A Major Regional, Subduction-Related Magmatic Event That Culminated In Emplacement Of The 2.73-2.79 Ga Granitoid Suite In The Batholith Exposed In The Beartooth Uplift (Wooden And Others, 1991). However, There Is No Evidence That The Magmatism That Formed The Stillwater Complex Is Related To Convergent Margin Tectonics And Magmatism
Alteration processes:	None Related To Ore-Forming Process
