Geologic structures

Type of structure Regional
Structure description Ne-Trending Folds Overturned To The Nw
Type of structure Local
Structure description Along The Contact Between Felsic Tuffs And A Massive Rhyolite Flow. Bedding Is N 10 E Dipping 10 Deg Nw And Cleavage Is N 17-35 E And Dipping 40-60 Nw.

Ore body information

  • General form FLAT-LYING STRATABOUND
    Strike N 10 E
    Dip 10 NW
    Thickness 1M
    Length 320M

Controls for ore emplacement

  • Silicified Zones Along Lithologic Contact

Comments on the geologic information

  • PODS OF SERICITIC AND SILICA-RICH TUFF HAVE BEEN ALTERED ALONG A LITHOLOGICuCONTACT. MINERALIZATION IS DISCORDANT TO CLEAVAGE BUT GENERALLY CONFORMABLE TOuBEDDING. FINE FREE GOLD IS ESPECIALLY ABUNDANT IN THE OXIDIZED UPPERuPORTIONS OF THE DEPOSIT. COUNTRY ROCK IS BRECCIATED.
