The Yellow Dog occurrence is located 2.1 kilometres northwest of Claw Mountain about 257 kilometres northwest of the community of Germansen Landing.

The 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. Stuhini volcanics have been intruded by the granodiorite to quartz monzonite Black Lake Suite of Early Jurassic age 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 Yellow Dog showing is underlain by Stuhini Group porphyritic andesites, tuffs, agglomerates and minor siltstone. Most of the rocks exhibit weak to moderate propylitic (epidote-chlorite) alteration. The units are offset by a fault striking 110 degrees of uncertain amplitude. The showing consists of a narrow (15 centimetre) malachite-stained quartz vein hosted within pyritic porphyritic andesite. Original sampling of the vein in 1985 yielded 50.0 grams per tonne gold and 84.7 grams per tonne silver (sample 001, Assessment Report 15069). In follow-up sampling in 1987, a grab sample from the vein assayed 6.07 grams per tonne gold and 39.40 grams per tonne silver (Assessment Report 17218).

In 2004, search for the previously known Yellow Dog showing on Claw 1 did not note any zones of significant mineralization other than thin (less than 30 centimetres) and isolated quartz veins exposed in an old, sloughed trench. Sampling in the Yellow Dog area resulted in anomalous gold, silver and copper values being obtained. In 2004, rocks from the Golden Lion and Yellow Dog areas on the Claw claims displayed argillic-propylitic alteration.

Mineralization at the Golden Lion zone, located 4.3 kilometres southeast of the Yellow Dog, appears to be related to a northwest-trending structure that can be traced for up to 3 kilometres. Mineralization occurs along the southern limit of the structure, in its central parts (Mirko claims) and its northern sector, at the head of small creek hosting an anomalous gold in silt sample. The Yellow Dog showing does not appear to represent an extension of this structure, as little or no evidence of mineralization (or structure) was noted in traverses transecting its projected strike.

The Yellow Dog showing was discovered in 1985 on the Expeditor property by Expeditor Resources Group and reconnaissance soil sampling and prospecting was conducted. In 1986, an airborne magnetometer survey was flown over the Expeditor Resource Group claims. Based on these results, the 1987 field exploration program consisted of detailed mapping, VLF-EM and ground magnetics surveying and geochemical sampling consisting of the collection of 517 soil, 97 rock and 11 silt samples.

In 2004 and 2005, the Breccia-Claw property of Stealth Minerals Ltd. contained previously discovered occurrences Golden Lion (094E 077), Yellow Dog, Gord Davies East (094E 199), Gord Davies West (094E 198), and Har (094E 053). The 2004 field program completed on the Breccia-Claw claims by Stealth Minerals consisted of rock and soil sampling. Alteration identification via PIMA spectrographic analysis was done on 95 selected rock samples. A total of 349 surface rock samples were taken as float or outcrop samples. In 2005, Stealth Minerals collected a total of 37 surface rock samples from float or outcrop samples.

In 2017 and 2018, Evergold Corp. completed programs of prospecting, geochemical (soil and rock) sampling and an airborne geophysical survey on the area as the Golden Lion property.
