Workings at the site

  • Type of workings Underground
    Length 60.96M

Comments on the workings information

  • MINES DEVELOPED MOSTLY BY ADITS AND DRIFT TUNNELS DIRECTLY INTO VEINS OR AS CROSSCUTS TO VEINS FROM STEEP HILLSIDES; SHAFTS ON FLATTER GROUND IN VALLECITO BASIN AND EAST SILVER MESA; SURFACE PROSPECT PITS
  • CAVED ADIT

Comments on development

  • LITTLE AVAILABLE HISTORIC INFORMATION ABOUT DISTRICT. FIRST PATENTED CLAIMS SURVEYED 1880-81 IN COLUMBINE PASS-COLUMBINE LAKE AREA, THEN PROLIFERATION OF SURVEYS IN 1883 IN SAME AREA, AT JUPITER PEAK-GRIZZLY PEAK, AT AZTEC MTN, AND ON EAST SIDE OF CRYSTAL VALLEY. NEXT GROUP OF SURVEYS IN 1886-87 INCLUDED TRIMBLE PASS AND WEST SIDE OF CRYSTAL VALLEY, UPPER EAST SILVER MESA, UPPER CHICAGO BASIN. LAST MAJOR GROUP OF SURVEYS WAS IN 1900-13 AND INCLUDED AZTEC MTN-BULLION MTN, MIDDLE CHICAGO BASIN, EMERALD LAKE AREA, AND LOWER NEEDLE CREEK. DISCOVERIES MADE PROBABLY AT OR SLIGHTLY LATER THAN THOSE IN LA PLATA MTNS. MINT REPORT FOR 1882 CITED DEVELOPMENT OF THE 2-YR-OLD DISTRICT BUT NO PRODUCTION. MOST PRODUCTION PROBABLY REALIZED BEFORE 1900. USBM MINERAL YEARBOOKS CITE SMALL PRODUCTION IN 1905, 1906, 1917, 1935 AND 1936 (LAST YEAR REPORTED). GEOCHEMICAL SURVEYING FOR MO AND CORE DRILLING IN 1960 BY AMAX REVEALED NO ORE-GRADE CONCENTRATIONS. IN 1965-68 USGS AND USBM COMPLETED GEOLOGIC
  • MAPPING, STREAM-SEDIMENT AND ROCK SAMPLE ANALYSIS, AND MINERAL EVALUATION FOR HEAVY METALS PROGRAM AND WILDERNESS AREA APPRAISAL.
