Geologic descriptionThe Elmer prospect is known only by name on a small-scale map by Wright and Wright (1908, figure 18). Maas and others (1995) call it the Cape Horn prospect. Their samples from a 25-foot adit contained up to 25 parts per billion gold and 421 parts per million copper. The rocks in the Dolomi area are part of the Wales Group of Late Proterozoic and Cambrian age (Herreid, 1967). They are folded into a large dome centered over the eastern third of Paul Lake, and consist of several marble layers 200 to 1300 feet thick, interbedded with calcareous chlorite schist and marble. The Cape Horn prospect is near a contact between the schist and marble. |
