The Buck Creek occurrence is located 10.5 kilometres southeast of the community of Houston, on Bob Creek and tributary of Buck Creek.

Lower Jurassic Hazelton Group volcanics of the Telkwa Formation are located around the junction of Bob and Buck creeks. The rocks are comprised of andesitic to rhyolitic tuffs, flows and breccia. The most common unit is a massive tuff breccia with thin intercalations of accretionary lapilli and siltstone.

The hostrock for mineralization is a belt of altered felsic volcanics, 600 metres wide, exposed in the Bob Creek canyon. These volcanics are part of the Francois Lake Group, Upper Cretaceous Tip Top Formation, and are crosscut by quartz feldspar porphyry feeder dikes and breccias. Younger, Tip Top Hill volcanics overlie the felsic volcanics east of the canyon. These are comprised of altered andesitic tuffs and breccias which underlie Eocene Buck Creek volcanics comprised of fine grained dacitic lavas and breccias (Bulletin 78, Figure 1).

A gabbro stock intrudes the Jurassic and Cretaceous volcanics south of the canyon. Also, feldspar porphyry dikes intrude the Hazelton rocks. A potassium/argon age determination of biotite from the gabbro stock gives a Late Cretaceous age of 80.6 plus or minus 2.8 million years (Fieldwork 1985, page 123). The stock could be related to the Late Cretaceous Bulkley Plutonic Suite.

The Bob Creek canyon hosts a large gossanous zone, which is completely altered to an earthy mixture of sericite, kaolin, and limonite. The rock is oxidized and leached and hosts jarosite, hematite, hydrozincite and gypsum flakes in fractures. Mineralization occurs in veinlets, stringers and as minor disseminations in these hydrothermally altered rocks.

In the rhyolite breccia, sulphides occur in veinlets, disseminations or as coarse grains and fracture fillings. In 1984, drilling intersected mineralized quartz-carbonate stringers hosting pyrite, sphalerite, galena, marcasite, chalcopyrite and arsenopyrite.

The main exploration target is midway between the canyon and the north contact with the gabbro. The target is an elliptical 80 by 50 metre area with gold and silver assays ranging over 4 grams per tonne and 35 grams per tonne, respectively. The age of mineralization was determined as 78.1 plus or minus 2.8 million years from potassium/ argon analyses of sericitized biotite from a hydrothermally altered porphyry in the canyon area.

On the Buck group, two adits were driven along shear zones containing irregular stringers of galena, sphalerite with quartz and barite gangue. A selected sample assayed trace gold, 1450 grams per tonne silver, 7.0 per cent lead and 7.0 per cent zinc. A short adit driven on the right side of the creek exposed disseminations and small seams of pyrite, sphalerite and minor galena. A sample assayed 50 grams per tonne gold, 75.4 grams per tonne silver, 0.4 per cent lead and 1.8 per cent zinc.

In 1936, 77 tonnes of ore was mined from a 9-metre adit and produced 21.9 grams per tonne gold, 34.2 grams per tonne silver and 1.1 per cent zinc.

From 1984 to 1986, B.C. Resources Canada Limited completed soil geochemistry and geophysical surveys, trenching and 66 diamond-drill holes (6869 metres). From 1988 to 1990, Royalstar Resources Limited conducted reconnaissance geological mapping, geochemical and geophysical surveys and 17 diamond-drill holes (5046.8 metres). In 1990, Equity Silver Mines completed five diamond-drill holes (1206 metres) and 199 soil samples to determine the northeasterly extent of the alteration zone. Erratic gold values of up to 2.94 grams per tonne were encountered (Property File Placer Dome - Aziz, M.L., 1991).

Two distinct zones on Bob Creek were drilled in 2004; the Canyon and South, with the latter situated about 1.2 kilometres south of the former. A low grade mineralized body is present at the Canyon zone. Drilling at the zone intersected a massive dacitic flow breccia. Pyrite is variably disseminated throughout and commonly occurs within veinlets. Sphalerite occurs as disseminations or vein material. An unidentified black disseminated and vein mineral correlates with increases or decreases in gold, silver and zinc assays. The best intersection occurs from 75.28 to 303.87 metres, with grades of 0.547 gram per tonne gold, 2.6 grams per tonne silver, and 0.2816 per cent zinc (Assessment Report 27716). Gold, silver and zinc assays results support the historic DDH 88-2.

The South zone consists predominately of massive to laminated lithic or non-lithic fine to lapilli dacite tuff often conformably to erosively interbedded with fine grained quartz-feldspar(?) sandstone. Pyrite is dominant and occurs as disseminations or as vein fills and fracture coatings. In the feldspar porphyry, pyrite occasionally occurs as cores in plagioclase. Galena and sphalerite are not common, but are noted in veins. Sphalerite was noted disseminated in the sandstone unit varying from black to honey brown in colour. Chalcopyrite is trace occurring in veins. Overall mineralization was weak.

Claims were staked on the Bob creek canyon showings prior to 1914 and sampling carried out. The Buck group of 20 claims, located at the junction of Buck and Bob creeks, was owned in 1927-28 by Misters Carter, Quinn, Raynond, and Rush. An adit was driven about 6 metres at that time. The Horseshoe group (8 claims) also known under the names Rex, and Gold Brick, covered the Eob Creek canyon showings. In 1928, the claims were owned by G.W. Smith, E.E. Barnum, and A. and M. Des Brisay. Two adits, 13 and 4.6 metres long, were driven at that time. A.J. MacPherson and associates optioned the property early in 1933 and in September of that year incorporated Fouston Gold Mines, Limited. A small test mill was installed and during 1934 a total of 183 tonnes were milled; results were considered unsatisfactory.

The Risk and Hope claims (Bellefield Group) were located about 1.6 kilometres southwesterly from the Bob Creek canyon showings, on a ranch owned in 1928 by R. Hayes. Opencutting was done during the period 1928 to 1930; these showings were held in 1936 as the Ruby claim group. Similar showings on the Buck River southwesterly from the Ruby group, were held in 1936 as the Ark group.

Transcontinental Resources Limited optioned the property in 1952 and carried out detailed geological mapping. In 1957, G.W. Smith held the property as the Dot and LSod groups. Mindev Explorations (Alberta) Ltd. optioned the claims and carried out bulk sampling and diamond drilling; the option was subsequently dropped.

In 1965, Triform Mining Ltd. and Coast Explorations Ltd. jointly optioned 56 claims in the Dot, Rod, L.H., and G.S. groups from G.W. Smith. Work included a geochemical soil survey (169 samples), 4115 metres of overburden stripping, and trenching; the option was subsequently dropped.

From the late 1960s to 1990, numerous programs including geochemical and geophysical surveys, geological mapping, trenching, outcrop stripping, and drilling occurred throughout the Bob Creek property with a particular focus on the gorge and areas south of the gorge with only some exploration to the north of the gorge. Diamond drilling from 1978 to 1990 totalled at least 10,611.2 metres in 65 holes.

The Dot 3-5, Ton 1-8, Rod 4 and 6, and Luky 1-40 claims owned in 1968-69 by Lorne Hanson were under option to American Smelting and Refining Company. Prospecting, sampling, and 637 metres of diamond drilling in seven holes was carried out.

In 2003, three claim groups were staked. The 64-unit Bob Creek property was acquired by Royal Country Minerals Corp. then transferred to International Curator Resources Ltd., which subsequently changed its name to Canadian Gold Hunter Corp. Work in 2003 included re-locating grid lines, roads, and drill collars. In 2004, Canadian Gold Hunter Corp. drilled 1434 metres in five holes at the Bob Creek epithermal gold-silver prospect aimed at confirming gold assays from prior drilling. Geophysics included an 8.9 kilometre induced polarization survey and a 45.5 kilometre ground magnetic survey.

In 2011 and 2012, Quartz Mountain Resources Ltd. held the considerable Buck and Karma property which contained six mineral showings including the Bob Creek (093L 009), Irk (93L 265), Lewes River (093L 261), John (093L 059), and Shelford Hills (093E 085). In 2011, the company conducted 3906 kilometres of aeromagnetic surveying (Assessment Report 33176). As a result, the company concentrated on seven areas of interest designated from A to G. Area A contained the Bob Creek showing and Area D the Lewes River showing. In 2012, the company conducted 29.5 line-kilometres of induced polarization in work areas C and D. The company also collected a total of 1489 soil samples, 159 rock samples and 10 silt samples on the Buck and Karma properties. Of seven areas tested with soil geochemistry, only areas A, C, E and G had elevated results (Assessment Report 34048).

In late 2016, on behalf of R.J. Billingsley, geological mapping was undertaken over the northeastern part of the Buck project area, an area that had seen little exploration attention in the past. In addition, all previous drill logs were re-examined in order to better define the stratigraphy of the eastern part of the project area and to provide an interpretation of the distribution of mineralization and alteration that would aid further exploration.
