The Yellow Metal occurrence is a series of old showings located on the divide between the heads of Perry and Hellroaring creeks, at an elevation of approximately 2100 metres.
The area is underlain by thinly bedded quartzites of the mid-Proterozoic Creston Formation (Purcell Supergroup). These metasedimentary rocks (biotite facies of regional greenschist metamorphism) strike from 020 to 025 degrees and dip steeply west.
Locally, a zone of crushing is shot through with narrow stringers of quartz that yield colours of gold on crushing. This band of quartzites has a width of approximately 100 metres.
A short distance down the Hellroaring Creek slope, a 0.5-metre wide quartz vein parallel to the strike of the quartzites is defined by 7.5 centimetres of gouge on the hangingwall. The vein assayed 6.5 grams per tonne gold and 7 grams per tonne silver, and the gouge assayed 11 grams per tonne gold and 10 grams per tonne silver (Minister of Mines Annual Report 1926, page 127).
On the Perry Creek slope, a glassy quartz vein, up to 12 metres wide, yielded only trace gold values. Approximately 300 metres to the east, another quartz vein, striking 350 degrees and dipping 80 degrees west, occurs along the bedding of the quartzites, which are sericitic on the bedding planes. Assays in this vein are up to 24 grams per tonne gold for picked samples, or 1.7 grams per tonne over a width of 0.5 metre (Minister of Mines Annual Report 1915, page 109). A later report describes quartz veins up to 1.3 metres wide, striking northwest across bedding, or parallel to bedding, and containing minor limonite after pyrite with low gold values, up to 1.7 grams per tonne (Minister of Mines Annual Report 1921, page 127).
There are also occurrences of minor disseminated pyrite and chalcopyrite in talcose seams and associated quartz stringers, in a zone crosscutting the regional strike. Assays of this material yield up to 1.7 grams per tonne gold over 1 metre; a 1 tonne sample of the best material assayed 14 grams per tonne gold and a trace of copper (Minister of Mines Annual Report 1915, page 109).
In 1985, two samples (55560 and 55561) from the former shaft area assayed 30.5 and 19.3 grams per tonne gold (Assessment Report 14718).
In 1999, two float samples (Zing-99 and 100) from a trench and the former shaft assayed 14.41 and 31.90 grams per tonne gold, respectively (Assessment Report 26216). The following year, samples assayed up to 16.64 grams per tonne gold, 35.0 grams per tonne silver and 1.68 per cent lead (Sample ZING-00-22; Assessment Report 26589).
In 2002, rock samples (ZR-211) yielded up to 12.24 grams per tonne gold (Assessment Report 27090).
In 2003, diamond drilling yielded up to 0.484 grams per tonne gold over 17.5 metres, including 1.5 metres assaying 1.41 grams per tonne gold, in hole Z-03-16 and 2.0 metres assaying 1.29 grams per tonne gold, including 0.5 metre assaying 2.24 grams per tonne gold, in hole Z-03-15 (Assessment Report 27340).
In 2009, channel sampling yielded up to 4.86 grams per tonne gold over 3.69 metres (Assessment Report 31375).
In 2012, diamond drilling (Hole ZG12-02) yielded 0.50 gram per tonne gold over 22.83 metres, including 1.41 grams per tonne gold over 4 metres (Assessment Report 33853). This zone is correlated to the mineralized zone intersected previously by hole Z-03-16 in 2003.
A 0.91-tonne bulk sample is reported to have yielded 12.5 grams of gold or 13.7 grams per tonne gold (Assessment Report 17514).
During 1915 through 1921, the area was extensively prospected, with the development of several trenches and a shaft. In 1985, Trans-Artic Explorations completed a program of prospecting and rock sampling on the area as the Hawk 1 claim. The following year, Unique Resources completed a program of soil sampling and ground magnetic and electromagnetic surveys. In 1987, Chapleau Resources completed a program of soil, silt and rock sampling, trenching and geological mapping on the area as the Racki claims, Morgan property. During 1997 through 1999, programs of soil and rock sampling, geological mapping and ground electromagnetic surveying were completed on the area as the Zinger claims. During 2000 through 2002, National Gold Corporation completed programs of geological mapping and silt, soil and rock sampling on the area as the HS and Zinger claims. In 2003, Chapleau Resources conducted an extensive exploration program of surface prospecting, rock and soil sampling and 20 diamond drill holes, totalling 3317.2 metres, on the area as the Zinger property. In 2009, Ruby Red Resources prospected and sampled the area. During 2010 through 2013, SG Spirit Gold and PJX Resources completed programs of rock and soil sampling, geological mapping, airborne and ground geophysical surveying and two diamond drill holes, totalling 284.3 metres, on the area.
