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 (Deposit): VEIN
Comment (Workings): 2 ADITS, LOWER ABOUT 750 FT., UPPER 150 FT.
Comment (Geology): LODE FOLLOWS FAULT CONTACT OF DARK FISSILE SLATE AGAINST GABBRO & SERPENTINE. THE DARK SLATE CONTAINS UP TO 6 IN. THICK BEDS OF LIGHT-GRAY SANDY SLATE. SLATE CRUSHED & SHEARED CLOSE TO CONTACT, THOUGH NEARBY, THE ONLY ALTERATION EFFECT IS THE PRESENCE OF PYRITE FLAKES ON CLEAVAGE SURFACE. STRIKE IS N 20 W. DIP 80 W GABBRO IS ALTERED, IRREGULARLY, TO CRUSHED TALCOSE W CARBONATE LENSES. VEINLETS OF CROSS-FIBER AMPHIBOLITE ASBESTOS AT ONE SPOT, 6 IN. MAX. WIDTH, ARE CROSSED BY IRREGULAR QTZ. STRINGERS & THE AMPHIBOLITE IS REPLACED BY QTZ. QTZ. ALMOST COMPLETELY LACKING. AU SAID TO HAVE BEEN FOUND IN THIN FLAKES ON CLEAVAGE SURFACES OF DARK SLATE.
