Comments on the geologic information

  • Geologic Description = Christie (1974) briefly examined an irregular oval 10,000 by 5,000 ft (3 by 1.5 km) color anomaly developed within volcanic rocks. Pyrite is disseminated throughout volcanic rocks, some of which are bleached. Volcanic rocks include andesite and basalt, some of which are fragmental. No intrusive rocks were seen in outcrop; description suggests some may have been seen in float. Reported quartz float may indicate veining; however, float was only seen north of creek and was not seen farther upstream.
  • Age = Miocene or younger

Comments on the workings information

  • Workings / Exploration = Brief reconnaissance geologic mapping and collection of a few silt samples. Occurrence apparently has not adequately examined for epithermal gold vein potential.
