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 (Deposit): SMALL LENSES OF PYRRHOTITE, PENTLANDITE, CHALCOPYRITE AND PYRITE IN SERPENTINIZED PERIDOTITE; LENSES 10-20 FT LONG, MAXIMUM 10 FT WIDE; ALSO SULFIDES DISSEMINATED IN GABBRO DIKE CUTTING PERIDOTITE

Comment (Location): BEST LOCATION: ADGGS GR 14, FIGURE 4, LOC. 1 LAND STATUS VALUE CALCULATED 6-94 USING GIS OVERLAY ANALYSIS WITH BLM 1:2,500,000 SCALE OWNERSHIP STATUS MAP (1991). ; INFO FROM LAND.ST :49?

Comment (Development): DISCOVERED IN EARLY 1950'S TRENCHING, MAPPING AND SAMPLING BY NEWMONT MINING CO. IN 1962; BENEFICIATION STUDIES UNSUCCESSFUL; COVERED BY ACTIVE UNPATENTED CLAIMS IN 1974

Comment (Geology): DISSEMINATED SULPHIDES WERE PROBABLY FORMED FROM IMMISCIBLE LIQUID DROPLETS IN LATE FRACTION OF PERIDOTITIC MAGMA FROM WHICH THE GABBRO DIKE WAS CRYSTALLIZED; SULPHIDE LENSES COULD HAVE BEEN FORMED BY MIGRATION OF LATE STAGE IMMISCIBLE FLUID INTO FRACTURES AND SHEARS
