Location and accuracy This occurrence is at 1,100 feet elevation in the headwaters of Dickens Creek, a east tributary to upper Nome River (Cathcart, 1922, fig. 15). It is 0.4 mile south of the Copper Mountain prospect (NM054).

Geologic setting

Geologic description

This is a copper occurrence that may be similar to other copper prospects in the area such as Copper Mountain (NM054), Copper King (NM051), and Copper Creek (NM053) that contain copper carbonate and copper sulfide-bearing, silica-rich zones in metacarbonate rocks. Country rocks at this locality are interlayered pelitic schist and marble (Thurston, 1985, figure 3A).
The location is shown in figure 15 of Cathcart (1922) due south of locally named Copper Mountain. Country rock was mapped as chloritic, feldspathic, and graphitic schist containing many limestone units. The area appears to have been first visited by Smith (1908, p. 240-242), then by Moffit (1913, p. 134-135).
