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 (Deposit): THE OLDER WORKINGS EXPLORE A SILICIFIED ZONE ABOUT 1.5 M WIDE IN QUARTZITE OF THE ORDOVICIAN COMUS FM. SPOTTY VEIN- QUARTZ OCCURS IN THE ZONE; HOWEVER,MUCH OF THE '' VEIN '' IS -A RESULT OF REPLACEMENT. THE WORKINGS ARE QUITE SHALLOW, AND N-EARLY ALL THE MATERIAL ON THE DUMPS-SEEMS ENTIRELY OXIDIZED. T-HE SILICIFIED ZONE IS APPARENTLY ALONG A THRUST FAULT WHICH IS- SINUOUS IN TREND DIPPING NW AT 25-50. IRON OXIDES OCCUR IN TH-E BRECCIATED SILICIFIED ROCK; GYPSUM IS PRESENT AS SUPERGENE F-RACTURE COATINGS. A SMALL PILE OF VEIN QUARTZ WITH ABUNDANT GA-LENA AND PYRITE WAS NOTED ON THE DUMP OF THE ADIT. EITHER THIS- HAS BEEN COLLECTED FROM ELSEWHERE ON THE DUMP, OR FROM OFF TH-E PROPERTY. IT WAS NOT SAMPLED. THE ROCK ON THE HEAP LEACH PAD- IS MOST PROBABLY FROM DUMPS ON THE SMALL HILL JUST TO WEST
Comment (Workings): SILVER COIN SHAFT, AN ADIT, SEVERAL SMALL PITS, NUMEROUS BULLDOZER CUTS, A SMALL HEAP LEACH PAD, 2 NEW BUILDINGS, A HOUSE HIGHER ON- THE HILL (ACTIVE IN 1983 AND 1984)
Comment (Geology): 3 FT WIDE VEIN
Comment (Deposit): THE WORKINGS EXPLORE A VEIN IN SILICIFIED LIMESTONE AND BLACK SHALE. THE SILVER COIN SHAFT IS 165 FT DEEP ON A 30 INCLINE. ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT; 3 FIELD OBSERV
Comment (Development): LISTED AS AN ACTIVE MINE IN 1984 ALTHOUGH THERE WAS NO ONGOING ACTIVITY AT TIME OF EXAMINATION IN JUNE, 1984. HOWE-VER, A BULLDOZER WAS PRESENT NEAR THE BUILDINGS AND THE HEAP-L-EACH SPRINKLER LINES, ETC SEEMED CAPABLE OF OPERATION
