Comments on the workings information

  • TUNNELS; ACCESS TUNNEL 1075 FT. LONG TRAVERSES THE STRIKE OF THE VEINS; VEIN HAS BEEN EXPLORED BY MANY INCLINED BOREHOLES AND CORE DRILLING. IN 1966 SHRINKAGE STOPING WAS PLANNED, WITH 6000 FT. OF ADDITIONAL WORKINGS INCLUDING 2 LOWER LEVELS CONNECTED TO ADIT LEVEL BY A 400-FT. WINZE. A MILL WAS PLANNED.

    production 1982-1986; 1990-1992; 1993-1995: totalled 5,150,441 oz Ag; 1993-1994: 1,596,674 lbs. Cu, 1,061,408 lbs. Sb

Comments on development

  • DISCOVERER, OLOF OLSON COMPLETED MOST OF THE RELATIVELY SHALLOW WORKINGS ON THE VEIN PRIOR TO 1940. IN 1961 AND 1962, CALLAHAN MINING CO., UNDER LEASE AND OPTION, COMPLETED 5 DIAMOND DRILL HOLES TO TEST THE VEIN STRUCTURE AT DEPTH UP TO 1000 FT. DOWN. UNDER ASSIGNMENT OF LEASE AND OPTION, MID CONTINENT URANIUM DROVE A 1030-FT. CROSSCUT TUNNEL TO INTERSECT VEIN AT 350-500 FT. BELOW THE OUTCROP. ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT


    ACQUIRED IN 1960'S BY SUNSHINE MINING CO. (2/3 INTEREST) AND MIDCONTINENT URANIUM CO. (1/3 INTEREST). CONSTRUCTION OF A 550 TON PER DAY MILL BEGAN IN MAY, 1981. OPENING OF THE MILL IS SLATED FOR MARCH, 1982, EXPECTED TO EMPLOY 60 PERSONS AT MINE AND MILL. IN 1963, MID-COntINENT URANIUM CO. ACQUIRED LEASES AND OPTIONS ON THE MOHAWK AND SANGER MINES; AND STAKED THE CLIFF GROUP OF 28 CLAIMS COVERING THE INTERVENING GROUND BETWEEN THE 16 TO 1 AND MOHAWK PROPERTY. THE GROUP OF CLAIMS OWNED OR CONTROLLED BY MID-CONTINENT IN 1964 FORMED A CONTIGUOUS GROUP OF 67 CLAIMS FROM THE 16 TO 1 PROPERTY TO THE MOHAWK AND SANGER PROPERTIES.

    Exploration activity was suspended in 1995.
