The Yellow Metal is a series of old showings located on the divide between the heads of Perry Creek and Hellroaring Creek; it was extensively prospected in the 1915-1921 period. More recently, the showings were explored by Unique Resources as the Hawk property.
The area is underlain by thinly bedded quartzites of the Creston Formation belonging to the Purcell Supergroup of Middle Proterozoic age. These metasedimentary rocks (biotite facies of regional greenschist metamorphism) have a strike from 020 to 025 degrees and dip steeply west. On top of the ridge at an elevation of about 2100 metres, 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 about 100 metres. A short distance down the Hellroaring Creek slope, a quartz vein 0.5 metre wide 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, quartz veins up to 1.3 metres strike northwest across bedding, or parallel to bedding and contain 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 one 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). A glassy quartz vein up to 12 metres wide, on the Perry Creek slope, yielded only trace gold values. Some 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 0.5 metre width (Minister of Mines Annual Report 1915, page 109).
