Satelite View

The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments
Comment (Commodity): CU ORE MINERAL NOT GIVEN IN THE LITERATURE
Comment (Development): NO ACTIVITY AT TIME OF EXAMINATION IN 1983.
Comment (Deposit): PROMINENT, RESISTANT, SILICIFIED VEIN OUTCROP ABOUT 3 FT HIGH, 7 FT IN OUTCROP LENGTH, 2-3 FT WIDE, COMPOSED OF FE-AND MN-STAINED SILICIFIED QUARTZITE CUT BY A NETWORK OF QUARTZ VEINS. DIFFICULT TO DISTINGUISH QUARTZITE FROM QUARTZ VEIN, AS QUARTZITE IS SILICIFIED AND OPALIZED AND QUARTZ VEIN IS VERY FINELY CRYSTALLINE, SUGARY TO MASSIVE. THE "RIB" STRIKES N55W AND DIPS STEEPLY SW TO VERTICAL. PORTIONS OF THE VEIN ARE BRECCIATED AND INDICATE EMPLACEMENT ALONG A FAULT. THE DEPOSIT IS IN QUARTZITE, BUT BROWN, MARLY, FETID RECRYSTALLIZED LIMESTONE IS EXPOSED IN A SMALL PROSPECT NORTH OF THE SHAFT. LIMONITIC AND MN-RICH GOSSAN WAS SAMPLED FROM THE DUMP. GOSSAN IS HEAVY SILICEOUS OR EARTHY AND CONTAINS SOME BOXWORKS AND OPALINE COATINGS. PINK, FINE-GRAINED QUARTZITE CONTAINS NUMEROUS DRUSY QUARTZ-LINED YUGS AND SILICEOUS VEINLETS DEPOSITED WITHIN FRACTURES WITH VERY FINE-GRAINED OXIDIZED PYRITE.
Comment (Workings): ONE SMALL SHAFT SUNK ON SOUTHERN EXTENSION OF VEIN OUTCROP, AND ONE PROSPECT PIT 25 FT N OF SHAFT.
Comment (Geology): CU STAINED SHEAR ZONES NEAR TOP OF PROSPECT MOUNTAIN QUARTZITE.
