Location and accuracy This prospect is on the east bank of Glacier Creek at an elevation of 1,000 feet. It is in the NW1/4, section 36, T. 28 S., R. 53 E. of the Copper River Meridian. It is shown as number 8 on sheet 1 by Still and others (1991).

Geologic setting

Geologic description

Still and others (1991) describe this prospect as a 10-foot-long adit driven along a pyrite-bearing shear zone in limestone. Samples from the adit and its vicinity contained up to 0.59 ppm gold, 3 ppm silver, 1,100 ppm zinc, 550 ppm copper, and 140 ppm lead. The limestone unit is Paleozoic (MacKevett and others, 1974) possibly, Late Pennsylvanian or Early Permian (Eakin, 1919).
