The Jan copper occurrence is situated in the Jan 9 claim, approximately 8.5 kilometres southwest of Yedhe Mountain in the Muskwa Ranges in the Northern Rocky Mountains (Geology, Exploration and Mining in British Columbia 1970; 1970 claim map).

The occurrence is in a region known as the Muskwa Anticlinorium, a major north-northwest–trending structure characterized by moderate folding and thrust faulting. The structure consists of Middle Proterozoic (Helikian) rocks of the Muskwa Assemblage, as well as Paleozoic rocks (Geological Survey of Canada Map 1343A; Geological Society of America, Geology of North America, Volume G-2, pages 111, 639). All belong to Ancestral North America (Geological Survey of Canada Map 1713A). Northeast- to northwest-trending Proterozoic diabase dikes are common in the region.

The area is underlain predominantly by the Aida Formation of the Muskwa Assemblage, which comprises dolomitic mudstone and siltstone, and dolostone (Geological Survey of Canada Memoir 373). The Fox claims, located 3.5 kilometres to the east, were explored at the same time and have the same geological characteristics.

Not much information is available. The sedimentary rocks are intruded by diabase dikes which have northwest-striking shear zones along their margins. The shear zones contain quartz-carbonate veins mineralized with chalcopyrite.

Work History

In 1968, Churchill Copper Corp. Ltd. completed a program of geological mapping, rock sampling, a single diamond drill hole, totalling 117.0 metres, and a 3.7 line-kilometre ground electromagnetic survey on the area as the John claims. Some trenching was done in 1970.

In 2005, Twenty-Seven Capital Corp. completed a regionally extensive program of geochemical (rock, silt and soil) sampling and a 9002.0 line-kilometre airborne magnetic survey on the area as the Muskwa property. Also at this time, Aries Resource Corp. and Action Minerals Inc. completed a program of prospecting and sampling on the area as the Sox claims of the Trident Copper project.

In 2006, Bradford Mineral Explorations Ltd. conducted 4467.0 line-kilometres airborne magnetic and electromagnetic surveys on the area as the Trident property. Also at this time, Action Minerals Inc. completed seven diamond drill holes, totalling 380.4 metres, and a ground electromagnetic (VLF) survey on the Sox claims.
