Comments on the geologic information

  • THE PROSPECTS ARE LOCATED NEAR A ZONE OF LAG BOULDERS AND OUTCROP OF VERY LIMONITE-RICH (HYDROTHERMALLY ?) BRECCIATED SILICIFIED ANDESITE (ALTA ANDESITE). ENARGITE IS RARE ON THE DUMP; WELL-CRYSTALLIZED PYRITE IS EXTREMELY COMMON. PRESUMABLY THE SILICIFIED ZONE PRESERVED SULFIDES AT SHALLOW DEPTHS FROM SUPERGENE OXIDATION.
