The JEWEL occurrence, is located in the Dickson Range on a northeast-trending ridge above Roxey Creek, 3.3 kilometres east-northeast of Dickson Peak, 6 kilometres northwest of Gun Lake and 10 kilometres northwest of the village of Gold Bridge.

Hypothermal cobalt-sulpharsenide gold and nickel lenses lay within the margin of the Jurassic to Eocene Coast Plutonic Complex (Cretaceous Penrose Stock). Host rocks consist of granodiorite, minor hornblende-biotite-quartz diorite, diorite and gabbro, which are intruded by feldspar porphyry dikes. A broad, east trending and steeply south-dipping fault zone cuts the granodiorite near the eastern contact with older sedimentary and volcanic rocks of the Mississippian to Jurassic Bridge River Complex (Noel Formation black argillite, calcareous rocks and tuffs and serpentinized peridotites). To the southwest, the Penrose Stock intrudes Late Paleozoic to Mesozoic Ferguson Series cherts, argillites and limestones.

Massive serpentinite, probably correlative with the Permian and older Shulaps Ultramafic Complex, is cut by several east trending and steeply south dipping diorite and quartz diorite dikes. Irregular fissure veins with an average width of 15 centimetres occur most commonly along the dike contact as well as branching into the serpentinite. Streaks and pods of pyrite, arsenopyrite and chalcopyrite occur in sheared siliceous gangue with occasional quartz and calcite streaks. Oxidation is pronounced to over 15 metres depth.

One assay gave a high of 75.4 grams per tonne gold; another sample assayed 54.2 grams per tonne gold and 34.3 grams per tonne silver (Minister of Mines Annual Report 1937, page F9). From 1938 to 1940, 51 tonnes of ore was processed yielding 3732 grams of gold, 404 grams of silver and 199 kilograms of copper.

In 2019, mapping was completed along the Roxey Valley as well as detailed mapping at the Jewel prospect via rope access. At the Jewel area, a near-source float sample DGL005 of massive arsenopyrite, chalcopyrite, malachite assayed 81.24 grams per tonne gold, 7.52 per cent copper and 0.09 per cent cobalt. Outcrop sample LFLG023A of a brecciated vein containing arsenopyrite and chalcopyrite assayed 69.8 grams per tonne gold, 3.10 per cent copper and 0.28 per cent cobalt.

There are at least two adits and possibly a third. The Jewel prospect lies 1 kilometre northeast of the Little Gem prospect (092JNE068), on the same ridge above Roxey Creek and some of the workings discussed in older reports may be included in the Little Gem.

A structural analysis of the area, including the Little Gem, Jewel and Mount Penrose occurrences, was conducted for Goldbridge Holdings Ltd. in 2013, determining three cross-structural exploration potential locations.

Cobalt One Energy Corporation Inc. acquired the property in 2017 and subsequently conducted stream sediment, rock and soil sampling prospecting and mapping, electromagnetic and IP survey, petrophysics studies and diamond drilling through to 2022. A time-domain electromagnetic survey (FLTEM) was completed in the Jewel area in 2022.
