Comments on the geologic information

  • Geologic Description = Little Eldorado Creek drains the north side of Pedro Dome. Bedrock in the headwaters area consists of granodiortie on Pedro Dome and micaceous quartzite, quartz-mica schist and pelitic schist of the Fairbanks schist unit (Weber and others, 1992). These drift mines access deep aurfierous gravel in the Chatanika flats. Production figures for these drift mines have not been reported.

Comments on the workings information

  • Workings / Exploration = Mining by drift methods only. During the winter of 1995-1996, a crew of six mined 17,000 cubic yards of high grade gravel using low profile loaders and excavators. The gravel was sluiced during the summer months of 1996 (Swainbank and others, 1997). Underground placer operations continued in 1997 (Swainbank and others, 1998).
