The Jackstone Creek copper occurrence is situated in rugged terrain, approximately 1 kilometre west-northwest of the summit of Mount Irving and 8.5 kilometres south of Jackstone Creek, in the Stikine Ranges of the Cassiar Mountains of Northern British Columbia (map symbol on Geological Survey of Canada Map 42-1962).

The occurrence area lies in the Pitman Batholith, a large Lower Jurassic intrusion that is part of the Guichon Plutonic Suite in the Quesnel terrane. It is composed of well-foliated quartz diorite and granodiorite (Geological Survey of Canada Maps 42-1962, 1712A, 1713A; Geological Society of America, Geology of North America, Volume G-2, page 500). The rock is characterized by large, prismatic hornblende grains and white plagioclase. Much of the pluton is metamorphosed to greenschist grade, especially near faults. The Guichon Plutonic Suite is spatially and genetically related to Lower Mesozoic volcanics of island arc origin, representatives of which occur marginal to the intrusion, a few kilometres to the north.

No details of the mineralization are available. Minor copper stain (presumably malachite) occurs in a shear zone that trends 345 degrees (Geological Survey of Canada Map 42-1962, marginal notes).

Work History

In 2011 and 2012, Teck Resources Ltd. completed programs of prospecting, geochemical (rock and silt) sampling and a 6411.9 line-kilometre airborne electromagnetic (ZTEM) survey on the area as the Pitman property.
