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.

Comments
Comment (Deposit): IN 1992 THE OPERATORS BEGAN USING METAL DETECTORS AS AN UNDERGROUND GOLD LOCATION TOOL. AFTER 6 MONTHS OF EXPERIMENTATION, MORE THAN $1 MILLION WORTH OF GOLD HAD BEEN DETECTED AND RECOVERED. IN A 12 DAY PERIOD MINERS REPORTEDLY HAD DETECTED AND RECOVERED 12 KILOGRAMS OF GOLD. PREVIOUS TO THIS METHOD THE MINE WAS HAVING FINANCIAL DIFFICULTY. ; INFO.SRC : 1 PUB LIT
Comment (Commodity): NUMEROUS SML SHOOTS OF HIGH GRADE ORE WHICH MAY YIELD $200,000 - $1,000,000
Comment (Deposit): VEIN, ORE SHOOTS
Comment (Workings): 2 PRINCIPAL INCLINED SHAFTS W LEVELS DOWN DIP EACH 100 FT IN UPPER WORKINGS & EACH 200 FT IN LOWER WORKINGS
Comment (Geology): 5 - 15 AVE THICK VEIN IN HORNBLENDE, GRAPHITE SCHIST & AMPHIBOLITE SCHIST OF REVERSE FAULT W MOVEMENT 300 - 900 FT. VEIN STRIKES N 30 W CHANGING TO N - S TO THE N. DIPS 20 - 60 E, MAINLY 25 - 30 E. 3 LENTICULAR AREAS, WHERE QTZ IS SEVERAL TIMES AVE, OCCUR IN REGIONS OF FLAT DIP WHERE STRIKE CHANGES, & CONTAIN HORSES OF COUNTRY ROCK. BANDED VUGGY QTZ ENDS CONTAINS COARSE QTZ XTLS BELOW 1000 FT LEVEL. N & S OF PRODUCTIVE PART OF VEIN, IT SPLITS INTO SMALL STRINGERS. THERE ARE SEVERAL BRANCHES W ONLY A LITTLE QTZ AT SOME INTERSECTIONS. DRAG IN META CONGL INDICATES REVERSE MOVEMENT. OPHIR VEIN JOINS 16 - 1 S OF 16 - 1 SHAFT.
Comment (Production): AG, PB, CU, ZN PRODUCED AS BYPRODUCT. VEIN PROSPECTING BEGAN 1896 , BUT WAS DISCOVERED EARLIER DURING PLACER OPERATIONS. MOST PRODUCTIVE MINE IN SIERRA CO.
Comment (Development): ECON.COM: THE MINE HAS PRODUCES MORE THAN 31.1 METRIC TONS (1 MILLION TROY OUNCES) FROM ORE WITH AN AVERAGE CONTENT EXCEEDING 31 GRAMS (1 TROY OUNCE) OF GOLD PER METRIC TON. LUCAS,1992
