Comments on the workings information

  • CLUSTERS OF SMALL WORKINGS ARE SCATTERED THROUGHOUT CANYON. ENTIRE CANYON HAS OVER PRINT OF DRILL ROADS AND RELATED SURFACE EXPLORATION. SOME WORKINGS ARE OBLITERATED AND DUMPS HAVE BEEN REMOVED AND STOCKPILED AT MOUTH OF CANYON. CANYON CONTAINS SEVERAL OLD CABINS. SAMPLED WORKING CONSISTS OF A SHAFT 10-15 FT DEEP, AND INCLINED TO THE WEST.

Comments on development

  • AREA IS STAKED AND THE SITE OF RECENT (3-5 YEARS) EXPLORATORY DRILLING AND REWORKING OF DUMPS. A SMALL AMOUNT OF ORE WAS PROBABLY SHIPPED

Deposit IRREGULAR REPLACEMENT VEIN OF FE-RICH SULFIDE-BEARING TACTITE DEVELOPED IN GREENISH-WHITE MARBLE. BROWN TO GREEN TACTITE OCCURS IN AN IRREGULAR ZONE WHICH GENERALLY TRENDS NORTH. THE REPLACEMENT VEIN IS STEEPLY INCLINED TO THE WEST AT A HIGH ANGLE TO THE BEDDING BUT ALSO EXTENDS OUTWARD ALONG BEDDING PLANES EAST OF MAIN VEIN. SOME TACTITE HAS ALSO DEVELOPED ALONG E-W FRACTURES PERPENDICULAR TO THE MAIN BODY. THE MAIN N-S BODY HAS IRREGULAR CONTACTS WITH THE WALLROCKS AND CONTAINS LARGE GOSSAN PODS. THE BODY MAY HAVE DEVELOPED ALONG A SET OF INTERSECTING FRACTURES OR FISSURES. THE DUMP IS SORTED INTO TWO DIFFERENT KINDS OF TACTITE; 1. OLIVE-GREEN TACTITE CONTAINING FIRE-GRAINED CHALCOPHYRITE AND YELLOW SPHALERITE. 2. DARK (FE-RICH) RED-BROWN-GREEN TACTITE CONTAINING ABUNDANT, CRYSTALLINE BLACK SPHALERITE, SOME CHALCOPYRITE, PYRITE, AND IS ASSOCIATED WITH OR CONTAINS PODS OF HEMATITIC GOSSAN. THE TACTITE CONSISTS OF AN INTERGROWN MIXTURE OF EPIDOTE, CHLORITE, DIOPSIDE(?) CALCITE, AND
Deposit QUARTZ. SAMPLE 1764 WAS LAMPED AND NO SCHEELITE WAS OBSERVED. FE-RICH, HONEYCOMB GOSSAN ALSO FOUND IN ABUNDANCE ON DUMP.
