Geologic setting

Geologic description

The rocks near this occurrence consist of dacitic metavolcanic rocks, marble, and phyllite of the pre-Middle Ordovician Wales Group (Gehrels, 1991). In 1988, Hedderly-Smith (1999) collected a rock chip sample from an orange-weathering, iron-stained zone in calcareous, gray mica schist that contains unidentified disseminated sulfides. The sample contained 1,412 parts per million (ppm) copper, 5,370 ppm lead, 5,100 ppm zinc, 4.62 ounces of silver per ton, and 163 parts per billion gold. The zone was resampled in 1990 but the sample did not contain any anomalous metals.
