The Snipe Bay Nickel-Copper Prospect is a copper and nickel mine located in Alaska at an elevation of 561 feet.
About the MRDS Data:
All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.

Satelite View
MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Note: the land ownership field only identifies whether the area the mine is in is generally on public lands like Forest Service or BLM land, or if it is in an area that is generally private property. It does not definitively identify property status, nor does it indicate claim status or whether an area is open to prospecting. Always respect private property.

Comments
Comment (Deposit): MAGNETITE, PENTLANDITE, CHALCOPYRITE, PYRITE, AND PYRRHOTITE IRREGULARLY DISTRIBUTED IN HORNBLENDITE BODY (PROBABLY ALTERED GABBRO OR NORITE) THAT INTRUDED QUARTZITE AND SCHIST. ORE BODY IS POORLY EXPOSED, AND IS AT LEAST 265 FT. LONG BEFORE DISAPPEARING UNDER ROCK AND SOIL. WIDTH IS AT LEAST 125 FT. DEPOSIT CONTAINS DISSEMINATED BLEBS AND VEINLETS OF SULFIDES, AND A MASSIVE SULFIDE BODY 12 FT. LONG BY 4 FT. WIDE, ELLIPTICAL IN SHAPE.
Comment (Workings): SEVERAL PROSPECT PITS WERE DUG.
Comment (Geology): TERTIARY IGNEOUS INTRUSIVE (ALTERED GABBRO OR NORITE) IN CRETACEOUS BIOTITIC QUARTITE AND BIOTITE-QUARTZ SCHIST.
