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 (Geology): E SIDE OF MAJOR ALTERATION SILICIFICATION OF DISTRICT. SHEAR ZONE APPEARS TO TREND SW THRU CURTZ & GEORGIANA MINES, & THEN SE ALONG S SIDE OF MONITOR CANYON NEAR ZACA MILL. MINE DUMP HAS WHITE SILICFIED ROCK THAT CONTAINS MOSTLY FINE - TO - MEDIUM GRAINED MINERALS. SILICFIED HILL TOP STANDS OUT FROM SURROUNDING UNALTERED ANDESITE. IN PLACES THE SILICFIED ROCK IS IRON OXIDE STAINED.

Comment (Deposit): RESULTS OF DIAMOND DRILLING PROGRAM OF 1962 , BOYLES DRILLING, SALT LAKE CITY, ARE UNKNOWN. ; INFO.SRC : 1 PUB LIT

Comment (Deposit): ZONE OF SULFIDE MINERALIZATION

Comment (Workings): 1200 FT MAIN ADIT, SSE TRENDING, KNOWN AS 148 FT LEVEL. 480 FT SHAFT CONNECTED 922 FT N FROM PORTAL. ALSO 220 , 280 & 480 FT LEVELS CROSSCUTS EXTEND TO ORE ZONE, ALSO STOPINGS, WINZES. MAIN ADIT, SHAFT OPEN IN 1971 . WORKINGS OF GEORGIANA & CURTZ WERE FOR A TIME DRIVEN FOR ORE BODIES IN SAME ZONE.

Comment (Commodity): RESEMBLES OTHER DISTRICT PRODUCERS EXCEPT THAT ENARGITE IS MORE ABUNDANT IN LATE 19TH CENT A BODY OF ENARGITE MIXED WITH PYRITE WAS FOUND MEASURING 10 TO 15 FT THICK AND 20 - 30 FT LONG.

Comment (Location): UTM ACC. W 1/2

Comment (Production): SOME ORE WAS SHIPPED AS FAR AS SWANSEA, WALES FOR SMELTING. MINE PRODUCED FAIRLY STEADILY 1863 - 1904 ON FAIRLY LARGE SCALE. IN 1951 , 1952 & 1957 MINOR EXPLORATION WAS DONE.
