Location and accuracy | This old prospect is at an elevation of about 200 feet near an unnamed creek. It is about 2.6 miles south-southeast of the the abandoned town of Snettisham on the northern Snettisham Peninsula. The prospect is about 0.4 mile north-northwest of the center of section 22, T. 45 S., R. 72 E. |
Geologic descriptionLittle detail is available on the deposits on the west side of Gilbert Bay and in the basin of what is informally called Argenta Creek which heads near peak 1651. However, Redman and others (1989) found an open cut near the shore of Gilbert Bay and a sample that they collected of chlorite phyllite contained 400 ppm copper. Black phyllite about 1.5 miles upstream contained 0.6 ppm gold; a black phyllite in lower Argenta Basin contained 1.4 ppm Ag. (Also see SD007 for prospects at the head of Argenta Basin.) The rocks in this area on the Snettisham Peninsula are part of the Permian to Cretaceous metavolcanic unit of Gehrels and Berg (1992). | |
