The Jim occurrence is located along Beaver Creek about 1.6 kilometres from its confluence with Canyon Creek, 17.5 kilometres northwest of the north end of Dease Lake.
Chalcopyrite and molybdenite was first discovered in quartz veins in Late Triassic quartz monzonite to diorite intrusive rocks along Beaver Creek, about 1.6 kilometres south of its confluence with Canyon Creek. Granites to the north contain minor amounts of fine-grained molybdenite with some chalcopyrite and pyrite along fracture planes, and as disseminations throughout the rock. The intrusions are in contact with Upper Triassic Shonektaw Formation volcanic rock of the Takla Group.
In 2007, Paget Resources Corporation conducted exploration in the Canyon Creek area which is probably the location of the original Jim showing. Excellent exposures of biotite quartz monzonite are mineralized with chalcopyrite and/or molybdenite bearing quartz veins over an area of at least 300 metres (north-south) by 840 metres (east-west). Although disseminated pyrite with trace to 0.5 per cent chalcopyrite is abundant in some areas, mineralization is dominantly related to quartz veining, which locally is very strong approaching sheeted vein or stockwork densities. Veins locally contain significant amounts of potassium feldspar. Chalcopyrite and molybdenite are found mainly along vein margins, but fracture-controlled mineralization is also common. Molybdenite is coarse-grained in some veins. Quartz veins range from millimetric stringers to large veins up to 0.5 metre in diameter, but most commonly veins are in the 1-2 centimetre range. A rock sample (147709) analysed 1.5 per cent copper, 17.7 grams per tonne silver and 526 parts per million molybdenum (Assessment Report 29593).
Mineralized quartz monzonite is generally weakly altered, but very strong carbonate alteration is present in places and may be related to post-mineral faulting. Weak to moderate sericite(-chlorite) is the dominant alteration type related to mineralization. In most exposures, unmineralized quartz veins predominate over mineralized veins. Just south of the main exposures of mineralized quartz monzonite along a tributary of Beaver Creek, a structural zone cutting silicified to quartz-iron-carbonate altered andesite contains poddy sulphide mineralization, including minor chalcopyrite.
In 1971, the Jim 1-8 claims were optioned by Cassiar Asbestos Corporation Limited and a program of soil and silt sampling was completed; 255 stream sediment and 116 soil samples were taken and sent for analyses. In 2007, Paget Resources Corporation collected rock samples mainly from outcrops in the Canyon Creek area and from float boulders and subcrops in the Shield area (104J 027). In total, 22 rock samples were obtained from the Canyon Creek area, and 21 rock samples were obtained from the Shield area.
A map in the 1971 assessment report 3423 filed by Dolmage Campbell / UMEX indicates the locations of 5 drill holes drilled by UMEX in 1971 on the eastern portion of the property (MINFILE 104J 027) however they were not filed for assessment and the results for these holes are unknown. Locations of two of these 5 drill holes were discovered and recorded using a GPS. The locations were 427100 east, 6528700 north, elevation 1283.3 metres and 426129 east, 6529839 north, elevation 1297.4 metres.
Between 2007 and 2012 the area became a focus of exploration for porphyry-style mineralization. Geochemical surveys in the field were followed by catchment analysis and Fugro magnetic surveys were conducted on behalf of operator Sirex Exploration Canada Ltd. over the survey block which measured 10 by 12 kilometre (1317 line-kilometres) (Assessment Report 33775). The 2012 airborne magnetic survey conducted by Fugro outlined a multiphase intrusive body forming an arch-like magnetic response trending southeast-northwest along a distance of 8 kilometres. A total of 55 rock samples, 104 silt samples, 42 soil samples and 42 biogeochemistry samples were collected. The Fugro survey included coverage over both the Jim and Shield showings of the Copper Creek property and sampling was also completed in both areas.
In 2016, A helicopter-borne ZTEM electromagnetic survey was flown by Geotech Ltd. over Block 2016 of the Canyon Creek mineral claims, held by Christopher Baldys (Assessment Report 36494). A number of conductive structures of interest were identified. The Jim showing is contained within the survey boundaries but the Shield showing is located outside the survey, about 1 kilometre to the southeast.
In 2018, a team sampled the mineralized and altered rock exposures at the Jim MINFILE location of the Canyon Creek property (claim 940112), owned by Christopher Baldys. A total of 10 rock samples were collected. All samples collected showed some chalcopyrite, molybdenite and pyrite mineralization with various degree of oxidation expressed by malachite and goethite. Rock samples 100007 to 100012 were collected from this stop and represent the several phases of intrusion and mineralization observed at the stop. One sample with higher copper values yielded 0.356 per cent copper and 0.014 per cent molybdenum (Assessment Report 38020).
