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): ROCKS IN MINE AREA CONSIST OF BUFF-COLORED SHALE AND INTERBEDDED BLUE-GREY LIMESTONE WHICH HAVE BEEN INTRUDED BY GRANITE. THESE FORMATIONS ARE CUT BY NARROW DIKES ANDESITE AND OCCASSIONAL EAST-WEST TRENDING DIKES OF PEGMATITE AND APLITE. LIMESTONE OCCURS IN 4 PARALLEL RIBS BETWEEN TONGUES OF GRANITE IN AN AREA 1500'X2000'. SEDIMENTS STRIKE N-S, DIP 50 DEG-70 DEG E. SCHEELITE OCCURS DISSEMINATED IN EPIDOTE-GARNITE-QUARTZ TACTITE AREAS 30' TO 100' WIDE FORMED ADJACENT TO CONTACT. TWO MAIN MINERALIZED AREAS, AN EAST OF WEST ZONE, HAVE BEEN EXPOSED. WEST ZONE, 200'X1000', CONTAINS SCHEELITE IN NARROW WIDTHS, UP TO 0.3% WO3. THE EAST ZONE, 500' EAST OF WEST ZONE, IS MINERALIZED OVER AREA 50'-100' WIDE, 500' LONG. WITHIN THIS, SCHEELITE OCCURS IN SMALL SHOOTS, WITH VALUES RANGING FROM 0.25 TO 0.45% WO3 OVER WIDTHS OF 4' TO 8'. A 250-TON TEST LOT OF ORE, AVERAGING 0.3% WO3, WAS MINED FROM THE OLD DISCOVERY (EAST) PIT.
