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): THE IVANHOE VEIN WAS DEVELOPED BY SEVERAL SHALLOW SHAFTS, ONE OF WHICH WAS LATER SUNK TO A DEPTH OF 500 FT. THE RICHEST ORES WERE NEAR THE SURFACE; THESE WERE MINED BY STRIPPING THE HANGING WALL OF THE VEIN OVER AN AREA 70 BY 120 FEET. IN ABOUT 1914, A 4400-FT CROSSCUT WAS DRIVEN FROM THE WEST SLOPE OF PALMER MTN IN AN ATTEMPT TO INTERSECT THE VEIN AT A DEPTH OF 1560 FT (UMPLEBY, 1911). ; INFO.SRC : 1 PUB LIT

Comment (Geology): THE VEIN IS IN PHYLLITE AND ARGILLITE OF THE PERMIAN BULLFROG MOUNTAIN FORMATION OF THE ANARCHIST GROUP.

Comment (Production): HAND-SORTED, NEAR-SURFACE ORES MINED BETWEEN 1888 AND 1897 CONTAINED AS MUCH AS 1000 OZ/TON AG AND SEVERAL OUNCES OF AU. APPROXIMATELY 1000 TONS OF ORE WAS SHIPPED TO SMELTERS IN WASHINGTON AND MONTANA; SEVERAL SHIPMENTS AVERAGED 392 OZ/TON AG AND 1.2 OZ/TON AU (MOEN, 1976, P. 123; RINEHART AND FOX, 1972, P. 91).
