Location and accuracy The Starship prospect is located about one mile (1.5 km) northeast of the Bear Pass prospect on a northwest facing ridgeline at an elevation of 2,150 feet (655 m) in Section 20, T. 23 S., R. 25 E., of the Kateel River Meridian. Location is known to within about 125 feet (38 m).

Geologic setting

Geologic description

The Starship prospect consists of a smithsonite-bearing solution breccia in dolomite and limestone of the Paradise Fork Formation of Dutro and Patton (1982); this is unit 'Sic' of Andrews and Rishel (1982). Zone of mineralization measures about 15 feet by 100 feet (4.5 m by 30 m) and is mainly in rubble crop. Age of host unit is Silurian (inferred), based on fossil control. (Patton and others, 1980; Dutro and Patton, 1982; Schmidt, 1997). The age of the mineralization is unknown. Grab samples from surface explorations of high grade mineralization contain up to 23.25 percent zinc and 0.14 percent cadmium. Mineralized rubble crop distribution indicates a relatively small and discordant mineral body.

Production and reserves

Workings or exploration The Starship prospect was found by WGM Inc. and Patino Ltd. in the late 1970s during base metal exploration on lands selected by Doyon Ltd (Andrews and Rishel, 1982). Grab samples from surface explorations of high grade mineralization contain up to 23.25 percent zinc and 0.14 percent cadmium. Mineralized rubble crop distribution indicates a relatively small and discordant mineral body.
Indication of production None
Reserve estimates None.
