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 (Development): IN 1950 THE GORMAN-HALL GROUP OF CLAIMS WAS PURCHASED BY THE MINERAL MOUNTAIN MINING AND MILLING CO WHICH ALSO OWNS THE WOODPECKER MINE TO THE EAST. THERE IS NO RECORD OF PRODUCTION OR DEVELOPMENT AFTER 1948. THERE ARE 6 UNPATENTED CLAIMS MAKING UP THE GROUP. SOME OF THE NAMES ARE BLUE BELL, SILVER PICK, JUMBO, FAIRVIEW, AND BADGER

Comment (Deposit): THE GROUP OF CLAIMS ARE INTERSECTED BY NUMEROUS SILLISIFIED MINERALIZED SHEAR ZONES WITH 4 PROMINENT VIENS BEING DEVELOPED THE MOST

Comment (Workings): NUMEROUS SHALLOW WORKINGS (PITS & CUTS, 2 100 FT INCLINED SHAFTS (55 DEGREE INCLINE))

Comment (Geology): MINERALIZATION ASSOCIATED WITH TERTIARY INTRUSION AND VOLCANISM. 15.8-17.4 M.Y. QUARTZ LATITZ EXPOSED 1 MILE WEST OF MINE

Comment (Location): UTM TAKEN TO TWO SHAFTS JUST WEST OF THE WOODPECKER MINE. ; INFO FROM LAND.ST :(1978)
