Significant Yes
Discovery year 1872
Year of first production 1882
Year of last production 1978

Comments on exploration

  • 1875 - DISCOVERED BY HOLLAND, ESTILL, AND MERRILL

    1881 - CHARLES CLARK FORMED THE ST. LOUIS SYNDICATE WHO PURCHASED THE GRANITE FOR $40,000 AND SPENT $75,000 ON DEVELOPMENT.

    1882 - BIMETALLIC MINING COMPANY ORGANIZED

    1885-1892 - $20,000,000 IN SILVER AND GOLD MINED.

    1898 - THE GRANITE MOUNTAIN AND THE BIMETALLIC WERE CONSOLIDATED



    THE GRANITE MOUNTAIN & BIMETALLIC MINES WERE WORKED SEPARATELY UNTIL 1898 - SINCE THEN HAVE WORKED AS ONE; BOTH LOCATED ON SAME ORE BODY. MILL CAPACITY 50 T/D. OPERATOR OF GRANITE TAILINGS: JOE METESH, PHILIPSBURG, MT.

Comments on the production information

  • 2 PRODUCTION PERIODS 1883-1893, 1898-1944.
  • 1885-1892 - $20,000,000 IN SILVER AND GOLD MINED.

    1883-1893 - $6,000,000 PRODUCED

Comments on the reserve resource information

  • ASSUMING A VEIN 4500 FT LONG BY 1500 FT DEEP BY 3 FT GIVES ABOUT 1,000,000 ST; THE AMOUNT ALREADY MINED. MINING AN ADDITIONAL 300 FT DOWN WOULD GIVE AN ADDITIONAL 200,000 ST WHICH IS BANISTER'S ESTIMATE OF RESOURCES FROM THE 1000 TO 1800 LEVEL. ASSUMING THAT THE VEIN CONTINUED 1500 FT AT A REDUCED LENGTH OF 3000 FT GIVES THE SECOND ESTIMATE OF 1,000,000 ST. GRADE PROBABLY DECREASES WITH DEPTH.

Workings at the site

  • Type of workings Underground
    Length 32000M
    Overall depth 800M

Comments on the workings information

  • WORKED FROM 5 DRIFT TUNNELS, TWO DEEP SHAFTS, AND A LONG ADIT WHICH DRAINS THE GRANITE MINE BETWEEN LEVELS 14 AND 15 AND THE BIMETALLIC MINE AT LEVEL 10.

Comments on development

  • THE GRANITE MOUNTAIN & BIMETALLIC MINES WERE WORKED SEPARATELY UNTIL 1898 - SINCE THEN HAVE WORKED AS ONE; BOTH LOCATED ON SAME ORE BODY. MILL CAPACITY 50 T/D. OPERATOR OF GRANITE TAILINGS: JOE METESH, PHILIPSBURG, MT.

General comments

Subject category Comment text
Deposit LODE HAS SEVERAL INTERSECTING VEINS WHICH TRANSVERSE THE GRANODIORITE AND JOIN AT SMALL ANGLES. THE GRANITE VEIN IS LARGEST AND RICHEST. IT HAS BEEN STOPED FOR AT LEAST 4500 FT ALONG THE STRIKE AND IN PLACES 2600 FT BELOW THE SURFACE. THE SOUTH VEIN IS THE MOST PRODUCTIVE FISSURE TO JOIN THE GRANITE.
