Comments on the geologic information

  • Geologic Description = This occurrence is defined by several anomalous samples reported by Still and others (1984, 1987). These two reports contain essentially the same data for this area. Metasediments and gossan are noted in the sample descriptions for those grab samples that contained the highest gold values, 0.066 to 0.316 ppm gold. Two sample descriptions are 'felsite with pyrite' and one of these contained 0.013 ppm gold. Another sample was described as 'calcite vein with pyrrhotite' and contained 330 ppm copper. One stream sediment sample contained 0.581 ppm gold.? Bedrock in the area is marble, metasediments and metavolcanics of the Cheetdeekahyu Group of Redman and others (1985). The probable Devonian or Triassic age of these rocks (Gilbert and others, 1987) establishes a maximum age for the mineralization.
  • Age = No older than the probable Devonian or Triassic age of the host rocks (Gilbert and others, 1987).
  • Age = Host rock is Triassic - Devonian.
