Comments on the production information

  • NEARLY 300 TONS OF ORE CONTAINING 2.75 % WO3 EXTRACTED BY THE END OF 1943 AND STORED ON DUMPS.

Reserves and resources

  • Type In-situ
    Estimate year 1945
    Commodity Subtype Grade units Group Importance Year

Workings at the site

  • Type of workings Unknown
    Overall depth 23M

Comments on the workings information

  • NARROW SECTIONS OF THE VEINS ARE MINED BY OPEN STOPING AND WIDER SECTIONS BY CUT AND FILL. EXTRACTION OF THE ORE IS BY MEANS OF A 100 M SHAFT AND BY ADIT.
  • 23 M SHAFT AT N END OF CLAIM. THREE SHAFTS 4-15 M DEEP AND SEVERAL PITS. 23 M SHAFT INCLINED TOWARD THE E AND PENETRATED GRANITE AT 10 M DEPTH. NO ORE WAS FOUND IN A CROSSCUT DRIVEN TO THE CONTACT ON THE 23-METER LEVEL.

Comments on development

  • THIS MINE HAS BEEN ONLY MAJOR FLUORITE PRODUCER IN SONORA.

General comments

Subject category Comment text
Deposit FLUORITE VEINS IN TERTIARY VOLCANIC ROCKS. THE ORESHOOTS HAVE BEEN MINED FOR OVER 200 M ALONG STRIKE, AVERAGE SEVERAL METERS IN WIDTH AND IN PLACES OPEN TO A 20 M WIDTH.
Deposit SIX SHORT LENSES OF TACTITE ON PROJECTIONS OF LIMESTONE THAT JUT OUT INTO GRANITE. AVERAGE DEPTH OF OUTCROPPING ORE BODIES WAS ABOUT 7 M, IN ALL CASES AT LEAST EQUAL TO STRIKE LENGTH. TACTITE COMPOSED PRINCIPALLY OF GARNET WITH LESSER AMOUNTS OF SCHEELITE, CALCITE, EPIDOTE, AND QUARTZ. SOME SECONDARY IRON OXIDES AND POWELLITE ASSOCIATED WITH SCHEELITE. SEVERAL SMALL KIDNEY-SHAPED MASSES OF NEARLY PURE SCHEELITE FOUND AT ABOUT THE 8-METER LEVEL IN SHAFT AT N END OF CLAIM, LYING EXACTLY ON THE GRANITE/LIMESTONE CONTACT. LARGEST KIDNEY WEIGHED ABOUT 6 KG AND WAS COATED WITH MUSCOVITE.
