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): USGS MF-413 (A-1), LOC. 30. WORKINGS ON POINT OF RIDGE BETWEEN TWIN CREEK AND SKOOGY GULCH AT AN ELEVATION OF 1,700 FT. LAND STATUS VALUE CALCULATED 6-94 USING GIS OVERLAY ANALYSIS WITH BLM 1:2,500,000 SCALE OWNERSHIP STATUS MAP (1991).

Comment (Deposit): SCHIST AND QUARTZITE CUT BY GRANITE DIKE; QUARTZ VEIN ABOUT 18 IN. THICK FOLLOWS A FAULT AND IS DEFINITELY YOUNGER THAN THE GRANITE. MINERALS IN VEIN INCLUDE PYRITE, ARSENOPYRITE, GALENA, SPHALERITE, SCHEELITE, AND FREE GOLD.

Comment (Workings): WORKINGS CONSISTED OF A VERTICAL SHAFT 100 FT DEEP AND 270 FT. OF DRIFTS ON VEIN; INACCESSIBLE IN 1931.

Comment (Geology): GRANITE AT END OF ONE DRIFT. VEIN OCCUPIES A FAULT PLANE. COUNTRY ROCK IS SCHIST, QUARTZITE, AND GRANITE.

Comment (Development): MINING 1911 TO PROBABLY 1913. A 10 STAMP STRAUB MILL WAS ERECTED IN THE SPRING OF 1912; 45 TONS OF ORE MILLED WITH RESULTS CONSIDERED UNSUCCESSFUL. MINE CLOSED, 1914.
