Mine Info

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 (Commodity): THE ORE IS MADE UP OF COPPER CARBONATES, AND LEAD CARBONATE, SULPHATE, AND SULPHIDE. FLUORITE OCCURS IN GANGUE.

Comment (Location): SECTION SUBDIVISIONS SE 1/4 SE 1/4 NW 1/4

Comment (Production): PRODUCED $700,000. WORTH OF ORE BY LATE 1880'S OR EARLY 1890'S, CONSIDERABLE PRODUCTION THEREAFTER.

Comment (Deposit): IT IS OBSERVED THAT WITHIN THE LOWEST PORTION ORE FORMED IN THESE LIMESTONE BEDS, EACH OF WHICH WAS UNDERLAIN BY A SANDY QUARTZITIC MEMBER AND THE MAIN OR HIGHESTONE BEING ALSO OVERLAIN BY QUARTZITE. THE CALCAREOUS MEMBER REPLACED WAS A FINE GRAINED DARK DENSE BED. THE ORE BEDS OR LENSES RANGED 2 TO 40 FT. IN THICKNESS.

Comment (Workings): ONE MAIN SHAFT AND ONE TUNNEL. TUNNEL IS 2,200 FT. LONG, SHAFT HAS 4,500 FT. OF DRIFTS. SHAFT IS 500 FT. DEEP.

Comment (Geology): FLUORITE IS FOUND AS A PIGMIFICANT GANGUE MINERAL. BOTH MASSIVE AND SEMICRYSTALLINE TYPES OCCUR IN LENSES. AN INCH THICK IN THE LIMESTONE AND IN THE ORE LYING ACCORDANT WITH THE BEDDING IN EACH BED.
