The Willy 2 occurrence is situated in the Swannell Ranges (Omineca Mountains) on the ridge immediately east of Duckling Creek, approximately 39 kilometres west-northwest of Germansen Landing.

The area is underlain by mesozonal plutonic rocks assigned to the Late Triassic to Early Cretaceous Hogem Intrusive Complex west of their contact with volcanic and sedimentary rocks of the Upper Triassic to Lower Jurassic Takla Group. 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).

Mineralization at the Willy 2 occurrence comprises stockwork potassium feldspar veinlets varying from 2 millimetres to 20 centimetres wide hosted by epidote-rich quartz monzodiorite. Sparsely distributed fractures also contain thin quartz veinlets with chalcopyrite, pyrrhotite and conspicuous malachite over an outcrop distance of 150 metres. Some chalcopyrite is also disseminated in the wallrocks.

A composite grab sample (74934) of mineralized intrusion assayed 0.506 gram per tonne gold, 8.9 grams per tonne silver and 1.3 per cent copper (Assessment Report 21428, page 21).

Work History

In 1990, Manson Creek Resources conducted a geological mapping and prospecting program supplemented by geochemical analysis of 235 stream sediment samples and 47 rock samples within the Discovery Creek property.
