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 (Location): UTM ACC. N 1/2 NE 1/4
Comment (Workings): 20-40 DEG. INCLINE, 225 FT. DEEP, 90 FT. OF DRIFTS ON 200 FT. LEVEL AND 40 FT. ON 60 FT. LEVEL. 1000 FT. NE ARE 6 SHAFTS OF UNKNOWN DEPTH. ONE OF THE SHAFTS KNOWN TO HAVE 600 FT. OF DRIFTS ON 180 FT. LEVEL. VALUATION OF DEVELOPMENT WORK BY U.S. LAND SURVEY SET AT $26848.
Comment (Geology): MOST HIGH-GRADE POCKETS FOUND IN VICINITY OF MAIN SHAFT BETWEEN 180 & 200 FT DIPS ON PARALLEL VEINS STEEPEN TO THE NE. SPECIMENS OF HOST ROCK WERE IDENTIFIED BY BOWEN AS HYDROTHERMALLY-ALTERED RHYOLITE-FELSITE.
Comment (Deposit): WORKED INTERMITTENTLY BETWEEN 1890 AND 1942 ; INFO.SRC : 1 PUB LIT
Comment (Production): ACCORDING TO BOWEN, U.S. BUREAU OF MINES RECORDS FOR 1891-92 SHOW ONLY SMALL FRACTION OF THESE AMOUNTS. 1914 RECORD, ACCORDING TO BOWEN, IS FROM UNPUBLISHED NOTES BY H.C. CLOUDMAN OF THAT YEAR. TOTAL PRODUCTION COMPILED FROM U.S. BUREAU MINES STASTICS IS EST. $25,000, BUT SOME EARLY PRODUCTION FIGURES MAY NOT HAVE BEEN RECORDED. NO OTHER INFO. AVAILABLE.
Comment (Deposit): GOSSAN OUTCROPS. VEIN IN FAULT SYSTEM. WITHIN ZONE ARE NUMEROUS PARALLEL AND AN ECHELON, NEARLY VERTICAL SUBZONES OF INTENSE SHEARING, A FEW TENS OF FEET THICK, WHERE SCHIST & LIMESTONE HAVE BEEN BRECCIATED. MAIN VEIN WHICH IS PARALLEL TO FRACTURES, CROSSES NEARLY VERTICAL FRACTURES AT ANGLES VARYING BETWEEN 20 AND 45 DEGREES. PARALLEL VEINS VARY IN THICKNESS FROM "THIN SEAMS" TO 2 FT.
