The ST occurrence is situated in the Duckling Creek area of the Swannell Ranges (Omineca Mountains), north of the Discovery (Duckling) showing (MINFILE 093N 089) and approximately 38 kilometres west-northwest of Germansen Landing. The ST claims were evaluated in the early 1970s by Passport Mines Ltd.
The area is underlain by Middle Triassic to Lower Jurassic Takla Group volcanics, which have been intruded to the north and west by mesozonal plutonic rocks assigned to the Late Triassic to Early Cretaceous Hogem Intrusive Complex. The plutonic rocks form an elongate batholith, extending from Chuchi Lake north to the Mesilinka River. The structural setting of the batholith and the intruded Takla Group is one of vertical tectonics associated with graben development (Bulletin 70).
Copper and molybdenum mineralization is reported to occur as a shear zone filling within contact phases between a monzonite intrusion and either a gabbroic border phase of the Hogem Intrusive Complex or hornfelsed Takla Group volcanics (Geology, Exploration and Mining in British Columbia 1971, page 214).
Work History
In 1971 James Todd and Associates completed a line cutting, mapping and soil sampling program on the ST claim group. The soil survey located no anomalous copper zones.
In 1991, Manson Creek Resources conducted an exploration program consisting of 84 soil samples on the Discovery Creek property.
