The Pik occurrence is situated in the Swannell Ranges (Omineca Mountains), approximately 20 kilometres north of Old Hogem and 60 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 to 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).
Reports from the early 1970s indicate that the area is underlain by three silica-deficient intrusive rock units: 1) leucocratic syenite, 2) monzodiorite and 3) pyroxenite. The syenite is described as being pegmatitic and megaporphyritic and belonging to the Duckling Creek Syenite Complex, a Middle Jurassic phase of the Hogem Intrusive Complex. The oldest unit, the monzodiorite, is medium-grained, mesocratic and potash enriched. Holomafic feldspathic pyroxenite, the least abundant rock type, occurs in small, irregularly-shaped pods in association with syenite. All of these rocks have undergone potassium feldspathization by fluids, which preceded and accompanied the emplacement of the syenite complex.
Chalcopyrite and bornite were the only sulphides observed in outcrop, occurring as rare disseminated intergranular blebs within the monzodiorite and syenite units, generally in close proximity to pyroxenite pods (Assessment Report 4522, page 4).
Work History
In 1972, Noranda Exploration Company Ltd. completed a soil sampling geochemical program on the Pik claim group.
In 2019, Teck Resources Limited conducted an airborne magnetic survey aimed at enhancing resolution of historical magnetic datasets and developing geological and structural understanding in the northeast portion of the Lorraine-Jajay and Jan-Tam-Misty mineral tenure. The survey identified potential new features in the Steelhead and Fox prospective areas
