Controls for ore emplacement

  • Ore In Schistose Andesite Near Contact With Highly Silicified Andesite; Also Some Relation To Shear Zones

Comments on the geologic information

  • NEAR THE ORE THE WALL ROCK IS BADLY METAMORPHOSED BY INTENSE SHEARING ACTION THAT HAS DEVELOPED SERPENTINE AND TALC AND IN PLACES CONVERTED THE ROCK DIRECTLY INTO A SCHIST. THIS ALTERED ANDESITE OFTEN OCCURS AS A HORSE TWO TO FIVE FT THICK SEPARATING TWO OVERLAPPING PARALLEL LENSES OF ORE. ; GEOL.DESC: SERIES OF OVERLAPPING TABULAR LENSES OF SOLID PYRITE AND CHALCOPYRITE

Workings at the site

  • Type of workings Unknown
    Area 64.752HA
    Overall depth 91.44M
    Overall length 579.12M

Comments on the workings information

  • 300 FT VERTICAL SHAFT WITH LEVELS AT 100 FT INTERVALS. A CROSSCUT AT THE 100 FT LEVEL PICKS UP THE ORE BODY 18 FT FROM THE SHAFT, WHERE AN EXPLORATORY DRIFT IS CARRIED ON FOR 60 FT FURTHER. AT THE 200 FT LEVEL THE ORE WAS PICKED UP 135 FT SW OF THE SHAFT, AND FOLLOWED BY INCLINED RAISES TO THE 100 FT LEVEL. THERE IS ABOUT 700 FT OF DRIFTING AND CROSSCUTTING ON THE 200 FT LEVEL. AT THE 300 FT LEVEL A CROSSCUT WAS RUN 574 FT TO THE SW WITHOUT ENCOUNTERING THE ORE (A QUICK GRAPHIC SOLUTION SUGGESTS THAT THE ORE SHOULD HAVE BEEN ENCOUNTERED BETWEEN 255 AND 300 FT, THE CROSSCUT MUST NOT GO SW OR THE ORE PINCHES OUT BETWEEN THE 200 AND 300 FT LEVELS). PERHAPS WINZING DOWN FROM THE 200 FT LEVEL WOULD BE THE NEXT APPROPRIATE ACTION.

Comments on development

  • SHAFT AND DRIFTS; 5000 FT RIBLET AERIAL TRAMWAY, CAPACITY OF 400 TONS/DAY, COMPLETED IN 1919; EXPLORATION IN 1967-1968.
