The Ted occurrence is situated in the Duckling Creek area of the Swannell Ranges (Omineca Mountains), approximately 2 kilometres east of the Lorraine occurrence (093N 002) and 61 kilometres northeast of Takla Landing.

The area is underlain by mesozonal plutonic rocks assigned to the Late Triassic to Early Cretaceous Hogem Intrusive Complex which have been emplaced into volcanic rocks of the Middle Triassic-Lower Jurassic Takla Group, east of the Pinchi fault zone. 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).

Mapping carried out in the area in the early 1970s identified several intrusive phases of the Hogem complex including diorite, monzonite, pyroxenite, pegmatite and syenite. The latter rock unit likely belongs to the Middle Jurassic Duckling Creek Syenite Complex. The more mafic phases also host accessory magnetite.

Several copper showings hosted within monzonite have been located on a ridge east of the Lorraine occurrence. Mineralization consists predominantly of malachite with bornite and chalcopyrite in shear zones containing potassium feldspar filling. This mineralization, together with abundant pyrite also occurs in float below these showings. Minor amounts of copper mineralization have also been found in association with a pegmatite.

In 2010, Teck Resources Limited conducted a spectral and lithogeochemical sampling of historic drill core and soil sampling program on the Too Good and Bishop zones of the Lorraine-Jajay property. Soils were sampled for pH and copper, molybdenum, zinc, lead, and gold with anomalous geochemical results within both sampled zones.
