Satelite View

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

Comments
Comment (Workings): THE WORKINGS EXPOSE THE VEIN ON 4 LEVELS. THE MAIN HAULAGE ADIT IS 1290 FT LONG AND INTERSECTS THE VEIN 972 FT F ROM THE ADIT PORTAL AND 440 FT BENEATH THE OUTCROP OF THE VEI N. FROM THE POINT WHERE THE ADIT INTERSECTS THE VEIN, OVERHEA D STOPES EXTEND 400 FT NO. AND 200 FT SO. WHERE THE ADIT INTE RSECTS THE VEIN, A WINZE HAS BEEN SUNK 100 FT. AT 50 & 100 F T BELOW THE WINZE COLLAR TWO WORKING LEVELS HAVE BEEN DEVELOP ED. THE UPPER ADIT, WHICH IS 200 FT ABOVE THE MAIN ADIT, INTE RSECTS THE VEIN 420 FT FROM THE ADIT PORTAL, & 200 FT BENEATH THE OUTCROP OF THE VEIN. THE ADIT CONTAINS OVER 700 FT OF DRI FTS AND A SHAFT THAT EXTENDS TO THE SURFACE. THE SHAFT CONTAI NS SEVERAL WORKING LEVELS FROM WHICH THE ORE HAS BEEN MINED.

Comment (Commodity): PRODUCTION FROM 1888 TO 1940; HUNTING, 1956 REPORTS THAT THE 100 FT LEVEL OF THE WINZE IN THE MAIN ADIT CONTAINS 2 ORE SHOOTS THAT TOTAL 350 FT IN LENGTH, AVERGE 2.5 FT THICK , AND CONTAIN 18 OZS AG PER TON.
