The Jim occurrence was discovered in 1988 along a high rugged ridge 11 kilometres west of Mount McNamara and 11 kilometres northwest of Claw Mountain, about 266 kilometres northwest of the community of Germansen Landing

The showing area is situated within a Mesozoic volcanic arc assemblage which lies along the eastern margin of the Intermontane Belt, a northwest-trending belt of Paleozoic to Tertiary sediments, volcanics and intrusions bounded to the east by the Omineca Belt and to the west and southwest by the Sustut and Bowser basins.

Devonian-Permian Asitka Group crystalline limestones are the oldest rocks exposed in the region. They are commonly in thrust contact with Upper Triassic Stuhini Group andesite flows and pyroclastic rocks. These Stuhini rocks have been intruded by plutons and other bodies of the mainly granodiorite to quartz monzonite Early Jurassic Black Lake Suite and are in turn unconformably overlain by or faulted against Lower Jurassic calcalkaline volcanics of the Toodoggone Formation (Hazelton Group).

The dominant structures in the area are steeply dipping faults which define a prominent regional northwest structural fabric trending 140 to 170 degrees. In turn, high angle, northeast-striking faults (approximately 060 degrees) appear to truncate and displace northwest-striking faults. Collectively these faults form a boundary for variably rotated and tilted blocks underlain by monoclinal strata.

The Jim showing is underlain by 160 degree striking, Stuhini Group tuffs and trachyandesites locally intruded by andesite dikes. Localized shearing, striking 160 degrees and dipping 80 degrees west, contains 1 to 2-metre-wide breccia zones with numerous quartz and quartz-calcite veinlets. Limonite is well developed within the breccia zones and in some of the tuffaceous horizons. Chalcopyrite, galena, covellite, and malachite occur as disseminations in some of the tuffs and in quartz and quartz-calcite veinlets associated with the shear zones.

A grab sample (CA-15 on Jim 1 claim) from a 2-metre-wide breccia zone within trachyandesite feldspar porphyry assayed 148.0 grams per tonne silver (Assessment Report 18465). A grab sample (CA-17 on JIm 1 claim) of a 2-metre-wide limonitic tuff assayed 27.0 grams per tonne silver (Assessment Report 18465). The mineralized zones occur sporadically for 500 metres along the ridge crest.

In 1988, on behalf of Prolific Resources Ltd., a field exploration program was completed on their 'Toodoggone' properties comprising the Stik, Fred, Adoog, Doog, Jim and Mike claims. The objective of the program was to locate and evaluate the gold potential of epithermal quartz breccia systems on the claims. Exploration consisted of extensive prospecting, geological mapping, lithogeochemical sampling (355 rock), hand trenching (1 trench, 19 metres), and soil sampling (722).
