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 (Location): LOCATION TAKEN FROM BOUTWELLS LOCATION MAP FOR THE PARK CITY DISTRICT, 1912 ; INFO FROM LAND.ST :1983

Comment (Deposit): SUB-ECONOMIC MINERALIZTION FOUND AT TWO LOCALITES. THE FISRST IS LOCATED AT THE HEAD OF A RAISE ABOUT 400 FT BELOW THE SURFACE AND NORTH OF THE SHAFT. HERE, COPPER AND IRON STAINING OCCURS IN A 6 INCH ZONE ALONG A BEDDING PLACE AT N24E, 270 NW. THE SECOND LOCALITY IS AT THE 600 FT LEVEL WHERE AN INTRUSIVE DIKE IS HIGHLY ALTERED AND IMPREGNATED WITH CUPRITEROUS PYRITE. THE INTRUSIVE ALSO CONTAINS VEINS OF CALCITE WITH SMALL BLOTCHES OF TETRAHEDRITE AND CHALCOPYRITE. NO ORE BODIES WERE FOUND UP TO 1912

Comment (Development): ACTIVE EXPLORATION FROM 1902 THROUGH 1912 BUT NO ORE WAS FOUND AS OF 1912

Comment (Workings): WORKING CONSIST OF ONE SHAFT AND ONE PROSPECT PIT. MAIN SHAFT IS 600 FT DEEP WITH DRIFTS ON THE 440 FT LEVEL. A RAISE FROM A DRIFT ON 440 LEVEL HAS A DRIFT ON THE 380 FT LEVEL. A DEEP ADIT FROM THE LITTLE BELL SHAFT, AT THE 1016 LEVEL COMES TO WITHIN 150 FT OF THE WEST QUINCY SHAFT

Comment (Deposit): NO PRODUCTION FROM PROPERTY AS OF 1912 ; INFO.SRC : 1 PUB LIT
