Location and accuracy This prospect is near the middle of the south side of the small lake, locally called 'Lost Lake', that is about 0.7 mile north of the west end of Harvey Lake It is in the NE1/4, section 22, T. 61 S., R. 79 E.

Geologic setting

Geologic description

Guided by an unpublished map dated 1933, Still and others (2002) located a 45-foot-long trench on four claims staked in the 1930s under the name 'Hope'. The trench exposes 12 feet of quartz rubble and 19 feet of a quartz vein in schist. The vein strikes N30W, and dips 45SW. A chip sample across 8.7 feet of the middle of the quartz vein averaged 4,400 parts per billion gold. Another trench is caved. The rocks in the area consist of felsic and intermediate volcanic flows and breccias, limestone, and argillite of the Hyd Group of Triassic age (Karl and others, 1999). In recent years, the prospect had often been covered by the claims of the 'Lost Show' prospect (PE029) on the north side of Lost Lake.
