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 (Workings): THE UNDERGROUND WORKINGS CONSIST OF A DOUBLE-COMPARTMENT 500 FT SHAFT AND A SINGLE-COMPARTMENT 200 FT SHAFT THAT CONTAIN SEVERAL WORKING LEVELS. DRIFTS EXTEND NORTH AND SOUTH ALONG THE VEIN AT THE 100, 200, AND 300 FT LEVELS OF THE 500 FT SHAFT, AND SOUTH ALONG THE VEIN AT THE 30, 70, AND 100 FT LEVELS OF THE 200 FT SHAFT. EACH LEVEL IN THE 200 FT SHAFT CONTAINS STOPES FROM WHICH ORE HAS BEEN REMOVED. THE EXTENT OF MINING IN THE 500 FT SHAFT COULD NOT BE DETERMINED DUE TO CAVING (1973).

Comment (Geology): GEOL.DESC: PARTS OF VEIN HIGHLY SHEARED

Comment (Production): UNKNOWN QUANITY OF ORE (HAND-SORTED) SHIPPED TO THE TRAIL SMELTER, CANADA, FROM 1958-1964; C.W. HARKNESS MADE A SMALL SHIPMENT IN 1967.

Comment (Deposit): MINERALS ARE CONCENTRATED IN A 2 FT SECTION OF THE VEIN THAT PARALLELS THE HANGING WALL.

Comment (Commodity): HIGH-GRADE AG ORE PRODUCTION IN 1889-1893, 1958-1964

Comment (Location): ON NW SLOPE OF RUBY HILL.
