The Antimony Rainbow Group Mine is a copper, tungsten, and antimony mine located in Valley county, Idaho at an elevation of 8,100 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.

Mine Info

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.

Comments

Comment (Location): CLAIMS STRETCH FROM INDEPENDENCE MINE SOUTH TO DAVIS MINE.

Comment (Commodity): STIBNITE CONTAINS AU AND AG

Comment (Production): SMALL LENSES & ZONES OF QUARTZ CONTAINING SCHEELITE & TETRAHEDRITE HAVE BEEN MINED IN THE PAST BUT PRODUCTION WAS SMALL

Comment (Development): ANTIMONY RAINBOW GROUP INCLUDES OLD DOKKA WORKINGS ON N. SIDE GOVERNMENT CREEK ; ECON.COM: THE MAIN TRENCH ASSAYS ABOUT 0.2% WO4 AND 3 OZ AG/TON

Comment (Workings): NUMEROUS PROSPECT PITS, TRENCHES, AND ADITS

Comment (Geology): FAULT TRENDS ABOUT N 10 DEG W AND DIPS STEEPLY TO THE WEST. ON EAST SIDE OF FAULT, THE ROCKS ARE PRINCIPALLY GRANODIORITE OF THE IDAHO BATHOLITH. TO THE WEST, THE ROCKS ARE PRECAMBRIAN GNEISSES & SCHISTS CUT BY THE DIKE SWARM.
