Comments on the workings information

  • WORKINGS INCLUDE OLD WORKING OF CLIMAX, REBELLION, PINON, WALKER, AND BUCKEYE MINES LOCATED NEAR THE CREST OF PIONEER RIDGE. MAIN DEVELOPMENT OF CRESCENT MINE WAS DONE FROM THAYNES CANYON VIA THE AETNA AND ANTELOPE TUNNELS, EXTENDING TOWARDS THE SOUTHEAST FOR ABOUT 2000 FT EACH . NUMEROUS LEVELS, STRIKING NORTHEAST DEVELOP THE CRESCENT FISSURE. BESIDES THE AETNA AND ANTELOPE ADITS, ONE ADIT, FIVE SHAFTS AND TWO PROSPECT PITS ARE LOCATED ON THE NORTHWEST SIDE OF PIONEER AND CRESCENT RIDGES

Comments on development

  • FIRST CLAIMS IN AREA LOCATED BY RUFUS WALKER AND ARE DISCOERD BY EHRAIM HANKS IN 1869. IN 1870, THE GREEN MOSNTER, PINON, AND BUCKEYE CLAIMS WERE LOCATED ALONG THE CREST OF PIONEER RIDGE. ORE SHIPPED BY THE PINON AND WALKER AND WEBSTER MINES UNTIL 1875. IN 1880, THE REBELLION AND CLIMAX MINES HIT ORE NORTH OF PIONEER RIDGE. IN 1882, THE CLIMAX, REBELLION, PINON WALKER, AND BUCKEYE MINES WERE CONSOLIDATED UNDER THE NAME CRESCENT. CRESCENT MINE ACTIVE UNTIL 1891. IN 1903, ALL PROPERTIES ALONG THE CRESCENT FISSURE UNITED TO FORM THE KEARNS-KEITH MINE. KEARNS-KEITH MINE. KEARNS-KEITH CONSOLIDATED WITH THE SILVER KING COALITION MINES CO. IN 1908 AND WITH UNITED PARK CITY MINES IN 1953

Subject category Comment text
Deposit ORE FIRST DISCOVERED ON PROPERTY WAS REPLACEMENT ORE IN THE THAYNES FORMATION AT THE FOOTWALL OF THE CRESCENT FISSURE ZONE. LATER WORKINGS DEVELOPED MAINLY REPLACEMENT. TYPE ORES IN THE THAYNES AND PARK CITY FORMATIONS. REPLACEMENT ORE WITHIN 150 FT OF THE CRESCENT FAULT ZONE. REPLACEMENT ORES HOSTED BY PURE LIMESTONE LENSES BETWEEN SANDSTONES OR IMPURE LIMESTONES, JENNY BED OF THE PARK CITY FORMATION PRODUCED THE MUST ORE. VEIN ORE BODIES LOCATED IN SHOOTS ALONG THE CRESCENT FISSURE ZONE.
