Ore body information

  • General form BROAD ZONE OF DISSEMINATED SULFIDES
    Width 3M

Comments on the geologic information

  • DEVELOPMENT WAS APPARENTLY CARRIED OUT IN A BRECCIATED ZONE IN GRAY-BLACK PORPHYRITIC RHYOLITE WITH BIOTITE IN THE GROUNDMASS. ORE IS IN HIGHLY WEATHERED SCHIST DERIVED FROM THE TUFF BRECCIA. ORE ZONE CONSISTS OF DISSEMINATED SULFIDE MINERALS IN THE SERICITE SCHIST. FELDSPAR PHENOCRYSTS, MINOR PYRITE AND MINOR BLEBS OF EPIDOTE ARE PRESENT. THE BRECCIATED ZONE IS BLEACHED, SILICIFIED, AND SERICITIZED. LITTLE VEIN QUARTZ IS ON THE DUMPS. A FINE-GRAINED OLIVINE (?) GABBRO OR COARSE-GRAINED DIABASE INTRUSIVE IS PRESENT IN THE AREA, AND IT CONTAINS SPARSE DISSEMINATIONS OF PINK-BRONZE TO WHITE PYRRHOTITE.

Workings at the site

  • Type of workings Surface/Underground
    Overall depth 16M

Comments on the workings information

  • AROUND 1910, A SHAFT WAS OPENED ON THE PROPERTY TO A DEPTH OF 52 FT. WITH MINOR DRIFTING. TWO CROSSCUT TRENCHES AND AN OPEN CUT WERE ALSO OPENED. IN 1968, THREE PITS APPROXIMATELY 20 FT. BY 20 FT. BY 10 FT. AND A 200 FT. LONG TRENCH TRENDING N 30 W WERE AT THE MINE. THE TRENCH WAS ABOUT 5 FT. WIDE AND 3 TO 6 FT. DEEP. A FOURTH PIT ON A QUARTZ VEIN HAD BEEN BULLDOZED OVER.

Comments on development

  • CYANIDE PROCESSING WAS TESTED ON 150 TONS OF ORE WITH POOR RESULTS.
