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): MAIN WORKINGS ARE APPROX. 250 FT WEST OF FINNING RD. AND LIE SW OF A 4 ROAD INTERSECTION.
Comment (Deposit): ORE BODIES WERE LOCALIZED WITHIN A ZONE 100 FT WIDE 500 FT LONG AND WERE PARALLEL TO THE LOCAL TREND OF THE SHEAR PLANES, WHICH HAD THE ABOVE STRIKE.
Comment (Workings): WORKINGS CONSISTED OF A SERIES OF SHAFTS, SHORT DRIFTS AND NUMEROUS SHALLOW SURFACE WORKINGS. ALL WORKINGS ARE COMPLETELY FILLED WITH DEBRIS OR FLOODED (1975)
Comment (Geology): DEPOSIT OCCURS IN A MASS OF ULTRAMAFIC ROCKS THAT HAS INTRUDED A SEQUENCE OF MARINE SEDIMENTS THOUGHT TO BE A PART OF THE PALEOZOIC CALAVERAS GROUP. THE EASTERN EDGE OF THE ULTRAMAFIC MASS IS COLLINEAR AND PROBABLY PART OF THE MELONES FAULT ZONE.
