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.

Comment (Development): GEOCHEMICAL ANALYSIS OF SEDIMENT SAMPLES, BEDROCK SAMPLES, AND PAN CONCENTRATES

Comment (Deposit): SHEAR ZONES IN HYDROTHERMALLY ALTERED QUARTZ PORPHYRY CONTAINS PYRITE STRINGERS TO 0.5 IN WIDE.

Comment (Workings): NO WORKINGS. OCCURRENCE ONLY

Comment (Geology): HYDROTHERMALLY ALTERED QUARTZ PORPHYRY AND MAFIC TERTIARY VOLCANICS ON SOUTH AND NORTH RESPECTIVLY, CUT BY STREAM. QUARTZ PORPHYRY CUT BY SHEAR ZONES WHICH CONTAIN PYRITE STRINGERS

Comment (Deposit): PYRITE STRINGERS CONTAIN HIGHEST CONCENTRATIONS OF AU. ENCOURAGING VALUES FOR GOLD INDICATE MORE INVESTIGATION NEEDED. ; INFO.SRC : 1 PUB LIT
