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 (Development): ONE OF THE OLDEST MINES IN THE DISTRICT (INACTIVE)
Comment (Geology): MINE IS DEVELOPED BY ONE VERTICAL AND FOUR INCLINED SHAFTS. DUMP MATERIAL IS MOSTLY DIORITE WITH SOME IRON-STAINED QUARTZ IS FOUND ON THE DUMP OF THE DEEPEST INCLINED SHAFT. THE DIORITE COULD NOT BE OBSERVED IN PLACE BECAUSE THE AREA IS COVERED WITH ALLUVIUM, AND THE ATTITUDE OF THE QUARTZ VEIN IS NOT KNOWN. THE VEIN QUARTZ ON THE DUMP CONTAINED 700 PPM SILVER AND 1293 PPM GOLD (WILLDEN AND SPEED, P 67).
Comment (Deposit): QUARTZ-CALCITE VEINS IN SHEAR ZONE IN DIORITE. IN OUTCROP VEIN IS ABOUT 3 FT THICK, BRECCIATED AND CEMENTED WITH H-EMATITE AND MN OXIDES. SMALL QUARTZ VEINS LACE DIORITE NEAR TH-E MAIN VEINS. THERE APPEAR TO BE AT LEAST 2 PARALLEL VEINS, ON-E PASSING THROUGH THE FALLON EAGLE SHAFT, WHICH STRIKES N40W,D-IPS 20 SW, AND A PARALLEL VEIN ABOUT 200 FT TO THE WEST STRIKI-NG N40W, DIP 55 SW. THE VEINS ARE 2-3 FT THICK AND APPEAR TO B-E LESS BRECCIATED TO THE SE OF THE MAIN SHAFTS. THE DIORITE WA-LLROCK IS LIGHT TO DARK GREEN DUE TO THE PRESENCE OF CHLORITE -(REPLACING ORIGINAL BIOTITE). FRACTURE SURFACES IN THE DIORITE- ARE COATED WITH EPIDOTE. VEINS ARE CONTAINED WITHIN THE DIORI-TE, BUT THE SURROUNDING HILLS ARE CAPPED BY LATER TUFFS AND BA-SALTS.
Comment (Workings): 2 VERTICAL SHAFTS, ONE INCLINE, PITS, TRENCHES (1985)
