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): MOST IMPORTANT VEINS ARE THE "STANDARD VEIN" EXPOSED FOR ABOUT 1,000 FT, CONTAINS POCKETS OF "GALENA, CERUSSITE, PYRITE, CHRYSOCOLLA AND ANGLESITE. "STANDARD EXTENSION" CROPS OUT FOR 600 FT., ITS 600 FT. SOUTH OF "STANDARD", STRIKES N 60 - 70 E, DIPS 75 NW TO VERTICAL, AVERAGES 2 FT. IN THICKNESS, COMPOSED OF COURSE CALCITE, QUARTZ, JASPER AND LIMONITE, LESSER AMOUNTS OF GALENA, CERUSSITE, HEMIMORPHITE AND CHRYSOCOLLA. UNNAMED VEIN, AVERAGES 2 FT. THICK, STRIKES N 60 E, DIPS 75 NW, SIMILAR TO "STANDARD" IN MINERAL CONTENT. POSSIBLY FAULTED SEGMENT OF "STANDARD VEIN".
