Controls for ore emplacement

  • Wnw-Ese Trending Shear Zone

Comments on the geologic information

  • QUARTZ VEINS AND SILICA CARBONATE ROCK ASSOCIATED WITH SERPENTINIZED ULTRAMAFIC BODIES. THE ULTRAMAFICS OUTCROP ALONG A FAULT ZONE AND ARE DISCONTINUOUS. RECONNAISSANCE SAMPLING ALONG THE FAULT ZONE TO THE SE DOES NOT INDICATE A CONTINUATION OF MINERALIZATION.
