Comments on the commodity information

  • TETRADYMITE (BI2TE2S) WAS NOT DEFINITELY RECOGNIZED BUT INFERRED ON THE BASIS OF ANALYSES OF NATIVE TE, RICKARDITE, AND ARSENOPYRITE. VULCAN AND MAMMOTH GOOD HOPE MINES ARE TYPE LOCALITIES FOR RICKARDITE AND WEISSITE. PETZITE PROBABLY IS THE PRINCIPAL GOLD-BEARING MINERAL. THE NEW TELLURIDE, VULCANITE (CUTE), WAS IDENTIFIED CIRCA 1960. GOOD HOPE MINE IS ONLY COLORADO OCCURRENCE OF BERTHIERITE (FESB2S4). ROSCOELITE NOT DEFINITELY IDENTIFIED BUT INFERRED ON BASIS OF ASSOCIATION WITH TELLURIDES.

Comments on the production information

  • PARTIAL PRODUCTION RECORD FOR COMBINED MAMMOTH GOOD HOPE AND VULCAN MINES. COLO. DIV. MINES CITES PRODUCTION FOR 1916 AND 1918 BUT NO FIGURES WERE INCLUDED. PRODUCTION FIGURES FOR 1894 TO 1916 NOT AVAILABLE. PRODUCTION FOR 1925 CITED ACTUALLY AS CEMENT COPPER RATHER THAN CONCENTRATES. IN ADDITION TO MATTE SMELTER PROCESSING OF ORE AND DUMP MATERIAL, NELSON REPORTS TREATMENT OF MINE WATER LEACHED FROM OLD STOPES TO RECOVER CU BY PRECIPITATION ON SCRAP IRON.

Comments on the workings information

  • MINE DEVELOPED BY 735-FT-DEEP SHAFT WITH LEVELS DRIVEN AT 100-FT INTERVALS. LEVEL 1 HAS 500-FT DRIFT EAST AND 100-FT DRIFT WEST (OF SHAFT). LEVEL 2 HAS 550-FT DRIFT EAST AND 100-FT DRIFT WEST. LEVEL 3 HAS 600-FT DRIFT EAST. LEVEL 4 NOT OPENED BUT EARLIER REPORT CITES 60-FT DRIFT WEST OF SHAFT. LEVEL 5 HAS 600-FT DRIFT EAST. LEVEL 6 (PRINCIPAL WORKING LEVEL) HAS 200-FT DRIFT EAST WITH STOPES AND 25-FT WINZE SUNK ON VEIN. LEVEL 7 HAS 50-FT DRIFT EAST. ABOUT 300 FT WEST OF THE GOOD HOPE WORKINGS IS A 240-FT-DEEP CAVED SHAFT.

Comments on development

  • MAMMOTH GOOD HOPE AND VULCAN MINES ARE PRINCIPAL MINES IN DISTRICT, HAVING PRODUCED FROM 1898 TO 1904 AND INTERMITTENTLY THRU 1930. SULFUR WAS PRODUCED IN 1907. A 40-TON MATTE SMELTER WAS OPERATED ON SITE FOR A WHILE TO TREAT ORE. FROM 1916 TO 1926 GOOD HOPE MINE WAS OWNED BY GOOD HOPE MINING AND REDUCTION CO., WHOSE PRINCIPAL WAS ONE DR. WEISS (PRESUMABLY FOR WHOM THE TELLURIDE WEISSITE WAS NAMED). VULCAN PROPERTY WAS OWNED BY J.H. HIMEBAUGH. IN 1928 VULCAN, GOOD HOPE AND OTHER CLAIMS (HUMBOLDT, MS 16392; MILL SITE, MS 19920; WAR EAGLE, HUMMING BIRD, ROSE BUD, IRON CLAD, MS 10910) WERE CONSOLIDATED AND OPERATED BY VULCAN CONSOLIDATED MINES CORP. LAST REPORTED PRODUCTION WAS IN 1930, BUT ASSESSMENT WORK WAS CONDUCTED IN 1937 BY DIAMOND C MINING AND MILLING CO.

FORMATION OF NATIVE SULFUR MAY HAVE RESULTED FROM DOWNWARD DESULFURIZATION OR OXIDATION OF PYRITE OR BY PRECIPITATION FROM ASCENDING SULFURATED HYDROGEN GASES.
