The G occurrence, also referred to as the Discovery Zone or Area 1 (Assessment Report 18597), is exposed in a roadcut on Highway 24, 10 kilometres northwest of Little Fort.
The showing consists of a zone of variably oriented chlorite-calcite quartz veins, 1 to 3-centimetres wide, within faulted diorite and gabbro of the Dum Lake Intrusive Complex, near the contact with the Thuya Batholith. The veins are mineralized with pyrite and traces of galena. They were explored for their precious metal content (Assessment Report 18597) and yielded assays of up to 3.15 grams per tonne gold and 36.9 grams per tonne silver across 3.0 metres.
The Upper Triassic to Lower Jurassic Dum Lake Complex is comprised of ultramafic and mafic plutonic rocks that could be part of an Alaskan-type intrusive body. The mafic portions of the Dum Lake Complex are dominated by coarse to medium-grained gabbro and diorite but locally include clinopyroxenite, monzogabbro, microdiorite and tonalite (Fieldwork 2000). The ultramafic portion of the Dum Lake Complex includes an assemblage of variably serpentinized, locally talc- and carbonate-altered rocks consisting of clinopyroxenite, wehrlite and dunite. The Dum Lake Complex is truncated by granodioritic rocks of the Triassic to Jurassic Thuya Batholith on its southeast side. On its eastward side, Dum Lake Complex diorites and gabbros are in contact with massive andesites of the Upper Triassic Nicola Group and argillites, limestones and cherts of the late Paleozoic Harper Ranch Group (Fieldwork 2000).
A portion of the G claim property was staked in 1985 by Craven Resources Incorporated to cover potential skarn and shear-hosted mineralization at the Cedar occurrences (MINFILE 092P 172and 092P 170), located 1.5 kilometres east of the Discovery Zone. A program of geological mapping, soil geochemical sampling, panned stream sediment samples, lithogeochemical sampling and magnetic and VLF-EM surveying was completed by Pamicon Developments Limited (Assessment Reports 13519 and 14477). In February 1988, George Wolanski identified the Discovery Zone along a road outcrop on Highway 24 and staked the G claims. Esso Minerals Canada Limited optioned the property and in 1988 completed a program of soil sampling (364 samples), silt sampling (25 samples), heavy mineral silt sampling (13 samples) and lithogeochemistry (124 samples; Assessment Report 18597).
In 1991, Huntington Resources Inc. investigated geochemical anomalies south of the Discovery Zone and found float fragments with up to 4.15 grams per tonne gold and 89.1 grams per tonne silver. They completed 5.7 kilometres of magnetometer and VLF-EM surveying, soil geochemical surveys (535 samples) and lithogeochemical surveys (81 samples).
In 2010, Bull Rock Minerals Inc. carried out an exploration program consisting of prospecting, soil sampling and rock sampling. In total, 103 soil samples and 13 rock samples were collected and sent for analysis. In 2012, Oryx Minerals Inc. optioned the property and carried out a geochemical sampling program consisting of 219 soil samples and 10 rock samples. That year’s soil sampling program expanded the 2010 soil grid to the south and east. In 2014, exploration consisted of field sampling and reconnaissance. White Oryx Minerals Inc. (previously Oryx Minerals Inc.) collected 15 rock samples from soil anomalies identified during the 2010 and 2012 exploration programs, all of which returned negligible results.
After the original G claims lapsed, Michael Cathro staked the G2 claims over the area in 2014. The following year, an exploration program was conducted consisting of prospecting and soil sampling. In total, 96 soil samples were collected and sent for analysis, leading to the identification of several gold-copper soil anomalies to the south and west of mineralized boulders found on the original G claims.
