The Snow occurrence is located in northwestern British Columbia in the headwater region of Snippaker Creek a north flowing tributary to Iskut River. It is approximately 20 kilometres southeast of the Bronson Airstrip on Iskut River and 87 kilometres northwest of Stewart, in an area termed the Bronson Corridor.

The Snow area is underlain by an undivided assemblage of stratified rocks comprised of fragmental volcanics interlayered with sequences of argillite, banded siltstone, greywacke, conglomerate and minor impure limestones. Most of these rocks are believed to be correlative with the Lower Jurassic Hazelton Group (Unuk River Formation), but some of the lowermost members may correlate with the Upper Triassic Stuhini Group rocks.

The stratified rocks are intruded by sub-volcanic intrusives and plutonic rocks of the Coast Plutonic Complex, which range from Upper Mesozoic to Cenozoic in age. These stocks and dikes include granodiorite, quartz monzonite, syenite and feldspar porphyry, as well as Tertiary dikes and plugs of basalt and diorite.

Sulphide mineralization occurs throughout the claim area. The most significant mineralization occurs in the northeastern part of the property within what is known as the Snow zone. The Snow zone consists of quartz-pyrite-chalcopyrite veins and disseminations which are associated with patchy local silicification and propylitic alteration (chlorite, carbonate, epidote). The pyrite, chalcopyrite and associated malachite occur within tuffs, andesitic volcanics and granodioritic intrusives. Patchy showings of chalcopyrite, azurite and malachite are associated with quartz veining and fracture fillings in altered tuff and andesite. Numerous chalcopyrite-galena and sphalerite-bearing quartz veins, as well as galena and barite veins are also found in the northeastern part of the Snow zone. They appear to be small fracture controlled mineralized zones associated with contacts of small intrusives.

Sampling in 1973 within the Snow zone showed values up to 2.7 grams per tonne gold and 32.4 grams per tonne silver (Assessment Report 6030). In 1974, sampling of copper mineralization within the Snow zone returned values of copper, silver, lead and molybdenite. Chip sample M-C, taken from granite porphyry hosting chalcopyrite and malachite assayed 7.07 per cent copper, 0.003 per cent molybdenite, 0.01 per cent lead, trace gold and 82.97 grams per tonne silver. Another sample from altered, fine-grained tuff hosting chalcopyrite, malachite and azurite assayed 0.54 per cent copper, 0.003 per cent molybdenite, 0.02 per cent lead, trace gold and 6.17 grams per tonne silver (Assessment Report 5142).

The central portion of the Gossan 7 claim is underlain by medium to coarse-grained granodiorite and diorite intrusives, which are decomposed with clay, sericite and minor epidote alteration. A broad northwest trending shear zone crosscuts the intrusive and displays a rusty alteration zone and hosts up to 5 per cent pyrite. Minor malachite with traces of chalcopyrite occurs near the eastern edge of the altered shear zone. The western slope contains iron staining with malachite and azurite. In 1986, samples from the rusty, altered shear zone within the granodiorite assayed 0.44 gram per tonne gold, 8.1 grams per tonne silver and 0.48 gram per tonne gold, 2.8 grams per tonne silver, respectively (Assessment Report 15238).

In 1987, a grab sample taken from chloritized lapilli tuff in the Snow zone with 5 per cent pyrite and sphalerite assayed 0.031 gram per tonne gold, 1.6 grams per tonne silver, 0.2088 per cent zinc, 0.0129 per cent lead, and 0.0103 per cent copper. Another grab sample from a 3 by 4 metre pyrite-rich pod in chlorite-epidote altered andesite tuff within the Snow zone assayed 0.008 gram per tonne gold, 1.5 grams per tonne silver, 0.0188 per cent zinc, 0.0038 per cent lead, and 0.0619 per cent copper (Assessment Report 16892).

Several gossanous outcrops on top of the mountain were the targets of an attempted induced polarization survey in 1990. Only a limited amount of data could be obtained since the area is mainly outcrop or coarse talus, thus lacking places to inject sufficient current into the ground to obtain readings. At the end of 1990 field season, it was reported that the Snow Zone remained an interesting target.

Work History

The Kim 1-36 claims were held by Great Plains Development Company of Canada, Ltd. Work during 1972 to 1974 included reconnaissance geochemical soil and silt surveys, geological mapping, and a geochemical soil survey (98 samples) over 6.4 line-kilometres covering Kim 13-22, and 26.

Exploration in the Pins showing area (104B 111 and 115) located in the southern portion of property was first recorded in 1972 by Cobre Explorations. This work consisted of prospecting, geological mapping, soil geochemical surveys, magnetometer surveys and ground electromagnetic surveys.

The Pelican property was staked in 1982 by Mr. Chris Graf as part of the larger Gossan Property which extended a further 10 kilometres to the northwest. In 1983, Lonestar Resources Ltd. completed an extensive prospecting, regional mapping, silt sampling and soil sampling program over the entire Gossan Property (Assessment Report 11332). This program delineated five significantly anomalous areas.

In 1985, Western Canadian Mining Corporation signed an option agreement with Mr. Graf whereby Western Canadian could earn a 60 per cent interest in the Gossan Property. In 1987, Western Canadian completed a geological mapping and a sampling program over portions of the Pelican Property; this including 903 soil, 23 silt and 304 rock samples (Assessment Report 16931).

In August 1988, Cathedral Gold Corporation signed an option agreement whereby Cathedral Gold Corporation could earn Western Canadian's 60 per cent interest in two separate portions of the Gossan Property. In 1988, Cathedral Gold completed a rock chip sampling-prospecting program during which 237 rock chip and 383 soil samples were taken. The results returned from this program include: 0.5 metre wide quartz vein the area within the present Southeast Grid which returned a gold value of 6 grams per tonne, a float sample from the Snow Grid area which returned 11 grams per tonne gold and mineralized float near the Pelican Grid samples of which returned gold values of up to 3 grams per tonne gold.

In 1989, Aerodat Ltd. was contracted to complete an airborne electromagnetic and magnetometer survey over the entire property. This survey totalled 386 kilometres in flight length and outlined several electromagnetic and magnetic anomalies worthy of follow-up.

In 1990, Cathedral Gold Corp explored Pelican (Gossan) property, including the Southeast, Sericite - SJ (104B 318), Pins (104B 111 and 115), Snow (104B 117) and Lake (104B 028), Pelican (104B 214). They collected 494 soil and 240 rock samples and conducted 23.9 kilometres of ground electromagnetic surveying (VLF) and 1.1 kilometre of Induced Polarization (IP) surveying.

In 2006 and 2007, Hathor Exploration Ltd. completed a 7228.7 line-kilometre airborne geophysical survey on the area as the Georgia claims of the Iskut project. In 2008, Max Minerals Ltd. examined the property.

In 2009, Max Minerals conducted a limited rock and soil geochemical sampling program in and around the Snow occurrence (Assessment Report 31162).

In 2014, Colorado Resources Ltd. conducted a soil sampling program to the east and southeast of Snow, where moderate to locally strongly anomaly levels of zinc were reported over an 800 by 500 metre area. Rock sampling to the east of Snow noted strongly anomalous to high grade gold values from polymetallic quartz and quartz-carbonate veins and veinlets within weak to moderately altered granodiorite. Rock sample 1748066 reported 31.4 grams per tonne gold, 0.8634 per cent copper, 24.45 per cent lead, and 26.22 per cent zinc from a 4 centimetre quartz vein with chalcopyrite, sphalerite, and galena (Assessment Report 35184). Rock and chip sampling by Colorado Resources continued in 2015, 2016 in and around the Snow occurrence (Assessment Reports 35943, 36761).

Rock Sampling was also conducted in the Snow area by Colorado Resources in 2017, mostly on a target approximately 1400 metres east, referred to as Snow East. In this area, sampling resulted in anomalous gold with five samples returning greater than 500 parts per billion Au and four samples returning greater than 2000 parts per million Zn. Gold-zinc mineralized samples are associated with outcropping centimeter scale (wide) quartz veins mineralized with pyrite, chalcopyrite and sphalerite. The Snow and Snow East areas are also characterized by elevated potassium feldspars and epidote (Assessment Report 37604).

From 2015 to 2019, Fortify Resources Inc. collected and analysed boulders and talus fines along the south border of their Sericite East Property, in a deglaciated gossan zone approximately 260 to 360 metres north-northwest of the Snow occurrence. The 28 samples collected showed a 100 metre by 300 metre area of anomalous Au values with 10 samples ranging from 0.1 to 0.648 gram per tonne and anomalous Ag and Cu values (Assessment Report 38747).

Colorado Resources Ltd. announced its name change to QuestEx Gold & Copper Ltd. on September 16, 2020.
