The Julia showing is located about 80 kilometres south of Whitehorse, west of Partridge Lake.

The area is underlain by rocks of the Bennett Lake Caldera Complex. The complex consists of two nested calderas, an eroded structural dome, and a thick succession of pyroclastic and epiclastic rocks. The complex is surrounded by granitic rocks containing pendants. The caldera is located near the eastern contact of the Coast Plutonic Complex and the Whitehorse Trough. Plutonic rocks consisting of granite and granodiorite intruded in the Middle Eocene. Two small stocks of the Paleocene to Eocene Sloko-Hyder Plutonic Suite, consisting of high-level quartz phyric, felsitic intrusive rock, are mapped to the immediate east of the Jones (104M 060) and Julia occurrences.

Exploration began in the Partridge Lake area in 1979 when E & B Exploration Ltd. ran a regional exploration program for uranium. Doron Explorations Ltd. acquired the claims, now called the Golden Partridge property, and conducted a reconnaissance geological and geochemical program. A brief prospecting program was undertaken in 1987. Prospecting and sampling were conducted in 1988.

A 20- to 40-centimetre-wide quartz vein, with a few vugs exhibiting coxcomb texture, consists of fine-grained quartz with variable amounts of chalcedony. Gouge zones, up 0.5 metres wide, occur on both sides of the vein. The vein is sparsely mineralized with bands of fine-grained galena, sphalerite, pyrite, and as well as minor chalcopyrite, and a quartz sample in proximity (c. 350 metres from the vein) contains minor arsenopyrite as well. The vein, striking 65 to 70 degrees and dipping steeply north, is hosted in granodiorite.

A chip sample (63805) across 110 centimetres assayed 0.048 grams per tonne gold, 10.6 grams per tonne silver, 0.1826 per cent lead, 0.0422 per cent zinc and 0.0132 per cent copper (Assessment Report 18176). Silver values increase as galena and sphalerite content increases.
