Comments on the workings information

  • SEVERAL SHAFTS (INCLINED STEEPLY TO THE WEST) AND SHALLOW PROSPECTS ARE LOCATED IN AREA RECENTLY REDEVELOPED BY EXTENSIVE EXPLORATORY DRILLING. DRILL ROADS CONTOUR AROUND SLOPES NEAR WORKINGS AND EXTEND FOR SEVERAL MILES TO NORTH ALONG EASTERN RANGE-FRONT. NEAR WORKINGS, DRILL HOLES ARE SPACED AT 10-20 FT INTERVALS. REMAINS OF AN OLD AG SMELTER LOCATED AT THE SITE. DUMPS HAVE BEEN BULLDOZED AND TRENCHED.

Comments on development

  • NO ACTIVITY AT TIME OF EXAMINATION IN 1983, BUT AREA WAS STAKED AND HAD BEEN DRILLED IN PAST 3-5 YEARS

Subject category Comment text
Deposit 2 PROMINENT RIBS OF JASPEROID OUTCROP ADJACENT TO SHAFTS. OUTCROPS ARE FRACTURED, BRECCIATED AND CONTAIN IRON OXIDE BOX WORKS AND GOSSANY VUGS. A FEW OXIDIZED PYRITE "GHOSTS" NOTED IN OUTCROP. MAIN JASPEROID OUTCROP. MAIN JASPEROID OUTCROP STRKIES N10-20E DIPS 70-75 NW. JASPEROID RUBBLE INDICATES THAT IT EXTENDS NORTH SEVERAL 10'S OF FT. JASPEROID BODY SHOWS FRACTURE PLANES DEVELOPED PARALLEL TO THE TREND OF THE OUTCROP. THE BODY OBVIOUSLY MARKS THE TRACE OF A SILICIFIED, MINERALIZED (?) FAULT ZONE WITHIN THE LIMESTONE. AN ALTERED DIKE INTRUDES THE JASPEROID ZONE NEARBY TO THE SOUTH. SAMPLE 1761 CONSISTS OF CALCITE-CEMENTED LIMESTONE BRECCIA WITH GOSSANY(FE AND MN) PORTIONS AND CONTAINING PYRITE, CERUSSITE, AND MALACHITE ASLENSES, CLOTS AND FRACTURE COATINGS. COARSE CALCITE VEIN ON DUMP CONTAINS A FAIR AMOUNT OF PARTIALLY OXIDIZED PYRITE, ALSO. THE ROCKS ARE HEAVY AND MAY CONTAIN BARITE. SCATTERED GREEN MINERALS (COATINGS) ARE POSSIBLY
Deposit ANGLESITE OR SCORODITE. SAMPLE 1762 IS FROM THE JASPEROID OUTCROP ADJACENT TO MAIN SHAFT. IT IS HEAVILY STAINED BY FE AND MN OXIDES.
