    Overall depth 41.15M
    Overall length 365.76M
    Overall width 438.91M

Comments on the workings information

  • UNDERGROUND WORKINGS CONSIST OF ALMOST 3000 FT OF DRIFTS, CROSSCUTS, AND SHAFTS. THE MAIN ADIT FOLLOWS THE COLUMBIA VEIN FOR 1200 FT. ABOUT 420 FT FROM THE PORTAL, A SHAFT HAS BEEN DRIVEN 135 FT TO THE SURFACE. ABOUT 700 FT FROM THE PORTAL A WINZE HAS BEEN SUNK TO AN UNDETERMINABLE DEPTH ON THE VEIN. AT 466 FT FROM THE PORTAL A CROSSCUT EXTENDS 1440 FT TO THE NW. MANY SPARSELY MINERALIZED QUARTZ VEINS ARE INTERSECTED BY THIS CROSSCUT; ONE OF THESE VEINS IS THE FRANKIE BOY VEIN; THIS VEIN HAS BEEN DRIFTED UPON FOR 165 FT, MAINLY IN A NORTHEASTERLY DIRECTION. ABOUT 140 FT BEYOND THE FRANKIE BOY VEIN, THE CROSSCUT ENCOUNTERS A PEGMATITE DIKE. THE CROSSCUT CONTINUES 350 FT BEYOND THE DIKE, BUT DOES NOT EXPOSE ANY VALUABLE VEINS. AT ELEVATION 2300 FT AN ADIT HAS BEEN DRIVEN WESTWARD AT LEAST 800 FT (IN 1917). TWO VEINS HAVE ALREADY BEEN INTERSECTED, AS OF 1917; ONE VEIN IS 88 FT FROM THE PORTAL AND IS 11 FT WIDE; THE OTHER VEIN OF EQUAL WIDTH IS 380 FT FROM THE PORTAL. DRIFTS HAVE BEEN
  • DRIVEN TO THE NORTH AND SOUTH ALONG THE SECOND VEIN, EACH DRIFT IS 100 FT LONG.

Comments on development

  • ADITS, DRIFTS, AND SHAFTS; DEVELOPMENT AND EXPLORATION IN 1957, 1959, 1969, AND 1970. IN 1896 A SHAFT WAS SUNK ON THE COLUMBIA CLAIM, AND SMALL SHIPMENTS OF HIGH-GRADE AG ORE WERE MADE; HOWEVER UCH OF THE ORE WAS ONLY MILLING GRADE AND COULD NOT BE SHIPPED TO DISTANT SMELTERS AT A PROFIT. IN 1902, MINERAL HILL MINING CO. WAS FORMED TO DEVELOP THE DEPOSITS. AN ADIT WAS STARTED ON THE COLUMBIA VEIN, AND BY 1906 THE VEIN HAD BEEN DRIFTED UPON FOR ABOUT 1000 FT. IN 1937 A 20 TON FLOTATION MILL WAS BUILT NEAR THE PORTAL OF THE COLUMBIA ADIT, AND DURING 1938-1939 SMALL AMOUNTS OF PB-AG CONCENTRATES WERE PRODUCED. SINCE 1940 SEVERAL COMPANIES HAVE UNDERTAKEN LIMITED DEVELOPMENT WORK AT THE WHEELER MINE.

General comments

Subject category Comment text
Deposit 13 PATENTED CLAIMS: NEW JERSEY, NEW YORK, FRANKIE BOY, OREGON, CALIFORNIA, WASHINGTON, IDAHO, VIRGINIA, NEVADA, FLORIDA, COLUMBIA, THOMPSON, AND MONTANA. THE CLAIMS WERE PATENTED BY BRIDGEPORT MINING AND MILLING CO. IN 1896.
Deposit ORE MINERALS CONCENTRATED INTO ORE SHOOTS TO 1 FT WIDE THAT PARALLEL THE VEIN WALLS; THE FRANKIE BOY VEIN IS THE RICHEST VEIN AND CONSISTS OF 1 FT OF WHITE GRANULAR QUARTZ, AND CONTAINS SCATTERED GRAINS AND LENSES OF ORE MINERALS. THE FRANKIE BOY VEIN STRIKES N35E AND DIPS 60NW. THE MO OCCURS IN A MO-BEARING PEGMATITE DIKE THAT IS 100 FT THICK. THE DIKE VARIES IN CHARACTER FROM PLACE TO PLACE. THE MO OCCURS AS THIN FLAKES AND RADIAL NODUALS ABOUT 0.25 IN. IN DIAMETER. IN THE LOWEST ADIT, ELEVATION 2300 FT, ONE VEIN IS 11 FT WIDE AND STRIKES N05W AND DIPS 46W; THE SECOND VEIN HAS A PARALLEL STRIKE, BUT DIPS MORE STEEPLY TO THE WEST THAN THE FIRST. AT THE FACE IN THE NORTH DRIFT, IN THE SECOND VEIN, THE VEIN IS ABOUT 5 FT WIDE.
