The Golden Stranger occurrence is located 6.0 kilometres southeast of Metsantan Lake and 11.0 kilometres west-northwest of the Lawyers mine (094E 066), on the west side of Lawyers Creek. Smithers is located 280 kilometres to the south. The occurrence lies within the Omineca-Cassiar Mountains in the north-central portion of the Toodoggone Gold Camp.
The Golden Stranger prospect 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. Permian Asitka Group crystalline limestones are the oldest rocks exposed in the region. They are commonly in thrust contact with Upper Triassic Takla Group andesite flows and pyroclastic rocks. Takla 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 Golden Stranger prospect is underlain by massive Lower Jurassic Toodoggone volcanics comprised of crystal lithic tuff and tuff breccia of rhyodacite composition with interbedded trachyandesite flows and flow breccias. The volcanic sequence is cut by a series of north to northwest trending deep seated fracture systems. Irregular, elongate aplitic dike-like bodies follow the north trending deep seated fracture/fault system. Alteration associated with the fault/fracture system ranges from disseminated pyrite to strong propylitic alteration with abundant epidote, chlorite, and carbonate. Associated with the aplitic intrusion is intense hydrothermal brecciation and associated silicification, veining and argillic alteration zones, hosting jarosite.
The Golden Stranger prospect consists of adularia-sericite type epithermal mineralization. Multistage quartz veining and silicified breccia crosscut both the altered volcanics and the aplitic rocks. Some composite veins host chalcedonic quartz or drusy quartz and locally amethystine quartz-lined vugs.
Two divergent breccia zones comprise the Main and West zones. The Main zone consists of a breccia-quartz, vein-shear system striking approximately north with a near-vertical dip. The zone is 50 metres wide and extends for 450 metres in length. Pyrite, galena, sphalerite, chalcopyrite, chalcocite, and covellite are hosted in a quartz-amethyst breccia system in hangingwall quartz-eye andesite in contact with an aplite dike. Although the zone is continuous, quartz veins within are not. The veins have an irregular, lensoidal, branching habit, with individual veins ranging from hairline to greater than 50 centimetres. The aplite is older than the mineralization but intrudes crystal tuff.
A north trending trench cut in the main zone in 1986 was sampled over 3.9 metres width and assayed 14.4 grams per tonne gold. The south most trench, located 390 metres on strike, yielded 1.37 grams per tonne gold over 4.0 metres width (Assessment Report 15633). In 1988, a follow up drill program was conducted on the Golden Stranger prospect. Drillholes 19 and 23 to 25 yielded significant gold and silver intersections. Some of the better intersections are as follows (Assessment Report 17000).

The West zone vein-breccia system is not as well developed as the Main zone. However, in 1986, a sample from the West Splay zone assayed 7.75 grams per tonne gold (Assessment Report 15633). Follow up drill results, in 1988, were not as encouraging as those from the Main zone, particularly for gold. The best results were from drillhole 3 from which samples analyzed 0.03 gram per tonne gold and 3.1 grams per tonne silver over a 3.1-metre interval, from 32.6 to 35.7 metres. The 15-metre interval from 26.8 to 41.8 metres in the same drillhole analyzed an average weighted value of 2.07 grams per tonne silver (Assessment Report 17000).
Preliminary data on the Golden Stranger property indicates 498,905 tonnes of ore grading 2.74 grams per tonne gold (Sutton Resources Ltd. Report to Shareholders, March 30, 1989 in Energy, Mines and Resources Canada Mineral Bulletin MR 223 (1989) - B.C. 268).
Preliminary geological mapping and geochemical rock sampling carried out in 1983 by Western Horizons Resources Ltd. on claims held by D. Price and G. Davies, resulted in the discovery of a mineralized quartz-breccia zone. Work in 1983 consisted of geological mapping and preliminary sampling of interesting outcrops. Only slightly anomalous concentrations of gold and silver were found during the initial examination.
In June 1983, Sutton Resources Ltd. and Redfern Resources Ltd. entered into a joint venture agreement with Western Horizons to earn up to one third interest each in the Golden Stranger and Golden Stranger 2 claims. Work by operators Redfern Resources Limited, Rule Resources Ltd., and Sutton Resources Ltd. (owner Western Horizons) reported in 1985 and 1987, included geological mapping, geochemical surveys comprising 240 soil, 22 silt, and 143 rock samples, an electromagnetic survey over 14 kilometres, a Very Low Frequency electromagnetic survey and magnetic survey over 7.0 kilometres, trenching, and 1859 metres of diamond drilling in 18 holes. Work in 1988 by Western Horizons included induced polarization and geochemical surveys and 1981 metres of diamond drilling in 15 holes to test the main zone at depth and along strike.
In 1994, Western Horizons Resources Ltd. carried out a detailed remote sensing study of the Golden Stranger claims area using ERS-1 SAR and Landsat 5 thematic imagery. Field checking of satellite imagery was done on the Golden Stranger property and surrounding area by S.C. Gower and E. Thompson.
In 2007, work resulted in a report on the lithology and mineralogy of a gold intersection (4.5 metres) in drillhole DDH 25. Diamond-drill hole GS-DDH-25 was collared to intersect the north end of the Main zone at an approximate depth of 140 metres below the top of the knoll and approximately 150 metres northeast of the high-grade zone cut in trenches excavated in 1985.
