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 (Workings): 120 FT ADIT CUTS QUARTZ MONZONITE PORPHYRY THAT CONTAINS DISSEMINATED CO CARBONATE. IN 1983, SEVERAL SURFACE CUTS/PROSPECT PITS, DOZER SCRAPINGS (ASSESSMENT WORK?) ALONG E-AND W- FACING SSLOPES OF CANYON

Comment (Deposit): VEIN CONTAINS OXIDES OF PB, AG & CU IN A QUARTZ GANGUE. ALSO ORE MINERALS IN A SET OF N-S CROSS-FRACTURES DIPPING 40-60E. AN ORE SHOOT AT THE INTERSECTION OF THE VEIN AND A FRACTURE WAS MINED TO A DEPTH OF 40 FT. ADIT FOLLOWS 3 FT WIDE HORNFELSIC ZONE ADJACENT TO QUARTZ PORPHYRY INTRUSIVE. BOTH INTRUSIVE AND SHALE UNITS ARE HIGHLY FRACTURED AND ALTERED. MINERALIZATION CONFINED TO INTRUSIVE. POST-MINERALIZATION SILICA-COATED ROCK SURFACES. ABOUT 50 YDS WEST OF MAIN ADIT, A MINOR SURFACE CUT WAS SAMPLED. SURFACE SCRAPING REVEALED QUARTZ VEIN CUTTING QUARTZITE. VERY FINE-GRAINED PYRITE, CHALCOPYRITE, AND GALENA/TETRAHEDRITE WERE FINELY DISSEMINATED IN THE QUARTZITE AND VEIN. ROCKS HIGHLY FRACTURED AND FE-STAINED. QUARTZ VEIN IS ESTIMATED TO BE 8 FT WIDE. VEIN SACCHROIDAL, VUGGY, LINED WITH EUHEDRAL QUARTZ CRYSTALS AT ADIT, VERY FINE SPRAYS OF MALACHITE WERE OBSERVED COATING EXPOSED ROCK SURFACES AND FILLING FINE FRACTURES OF THE PORPHYRY. ORE ON DUMP WAS SLIGHTLY GOSSANY. SHALE AND

Comment (Deposit): QUARTZITE BRECCIA OBSERVED ON DUMP.
