The Jimo 24 occurrence, first discovered in 1974, is located approximately 11 kilometres west of Mount McNamara and 10.5 kilometres northwest of Claw Mountain, about 265 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 Jimo 24 area is underlain by Stuhini Group basalts, trachyandesites, andesites, andesite dikes, tuffs and agglomerates. The units are locally sheared, fractured and brecciated. Ubiquitous chlorite and epidote are evidence of pervasive weak propylitic alteration.

The Jimo 24 showing mineralization occurs at two areas. The southern zone is hosted within fractured coarse grained trachyandesite feldspar porphyry; extensive malachite staining is present along fracture surfaces. The fracture planes, striking north and dipping 85 degrees east, are lined by calcite with chalcopyrite haloes. The mineralization is exposed over a 100-metre area. A grab sample (CA-14) assayed 17.8 grams per tonne silver (Assessment Report 18465).

Six hundred to eight hundred metres north of this zone, at the North zone, malachite stained trachyandesite feldspar porphyry contains disseminated blebs of chalcopyrite up to 2 centimetres in diameter. Two samples of this material assayed 27.00 and 23.00 grams per tonne silver (samples BB-16 and BB-17, respectively; Assessment Report 18465).

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).
