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 (Reserve-Resource): ALSO "SEVERAL MILLION" TONS OF ORE AT AVERAGE GRADE OF 0.6% CU

Comment (Location): DEPOSIT NUMBER IS THE MAP LOCATION NUMBER FROM MF-880A. LAND STATUS VALUE CALCULATED 6-94 USING GIS OVERLAY ANALYSIS WITH BLM 1:2,500,000 SCALE OWNERSHIP STATUS MAP (1991).

Comment (Deposit): SHEAR ZONE 180 FT WIDE AND 540 FT LONG IS TERMINATED BY A FAULT ALONG ITS NORTHERN SIDE. MASSIVE SULFIDE BODIES OCCUR ALONG WALLS OF ZONE, WHICH IS DELIMITED BY FAULTS. COUNTRY ROCK IN CENTER OF ZONE CONTAINS DISSEMINATED SULFIDES WITH POCKETS OF MASSIVE SULFIDES AND POCKETS OF BARREN GREENSTONE. MAGNETIC SURVEY INDICATES TWO LARGE UNEXPLORED MASSIVE SULFIDE BODIES TO THE NORTH AND TO THE SOUTH ON STRIKE WITH DEPOSIT.

Comment (Workings): 2850 FT OF UNDERGROUND WORKINGS, 3200 FT OF DIAMOND DRILLING AND SEVERAL OPEN CUTS & TRENCHES. FOR DETAILED MAP OF WORKINGS, SEE USGS BULLETIN 947-D, PLATE 23
