Comments on the geologic information

  • Geologic Description = This occurrence is in late Miocene volcanic rocks (Wilson and others, 1995). It is described as an altered zone in Tertiary rocks (Christie, 1974; MacKevett and Holloway, 1977). The alteration is argillic, possibly of fumarolic origin. The main commodity herein is speculated to be gold, based on its association with altered zones elsewhere in Tertiary volcanic rocks.
  • Age = Miocene or younger.
