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): SINGLE SHAFT, SHALLOW, CAVED. MOST OF DUMP WASHED AWAY DOWN DRAINAGE. GOOD CONDITION OF ACCESS ROAD PROBABLY MAINTAINED FOR HUNTERS.
Comment (Deposit): HYDROTHERMAL BRECCIA ZONE IN INTRUSIVE. FAULT ZONE IN WALL OF SHAFT IS FILLED AND CEMENTED WITH MASSIVE SUGARY QUARTZ AND CRYSTALLINE CALCITE VEINS WHICH ARE IN TURN IRON-STAINED AND COATED WITH MINOR PSILOMELANE, THE INTRUSIVE ON EITHER SIDE OF THE FAULT IS INTENSELY BRECCIATED AND CEMENTED WITH COCKSCOMB HYDROTHERMAL QUARTZ WHICH HAS ABUNDANT OPEN SPACES. THE QUARTZ CRYSTALS ARE VERY FINEGRAINED TO 0.5 INCH AND RADIATE FROM CENTRAL NUCLEATION POINTS AND EXTEND FROM THE BRECCIA FRAGMENTS. THE QUARTZ IS HEAVILY FE- AND MN- STAINED, AND FROM THE WEIGHT OF THE ROCKS, SUGGESTS THAT BARITE MIGHT BE INTERGROWN. PLATY, CRYSTALLINE CALCITE FILLS FRACTURES AND IS ALSO COATED WITH IRON AND MANGANESE STAINS. THE INTRUSIVE IS GRAY-GREEN (PROPYLITICALLY ALTERED?) EQUIGRANULAR AND STRONGLY WEATHERED, SHOWING ARGILLIC ALTERATION. SERICITE OCCURS LOCALLY. BRECCIA FRAGMENTS EXHIBIT MILLING. INTERSECTING THE MAIN FAULT ZONE ARE SETS OF N20E VERTICAL SHEARS. A VERY MINOR AMOUNT OF OXIDIZED PYRITE AND A
Comment (Deposit): LONE GRAIN OF GALENA IN THE QUARTZ CEMENT.
