The G-South occurrence occurs within the Quesnel Belt, located approximately 30 kilometers north of Quesnel. The area is underlain by Upper Triassic Takla Group mafic to intermediate flows, pyroclastic volcanics and argillaceous sedimentary rocks. These are intruded by coeval plutonic rocks of the Naver Intrusive Suite.

The G-South deposit is mainly underlain by augite porphyry, basaltic breccias and argillites which have been intruded by several rhyolite dikes. Sulphide mineralization occurs disseminated in the country rocks and in stockworks and breccia infillings with quartz, calcite, epidote and chlorite. There are two main types of mineralization: 1) disseminated and fracture-controlled pyrite, pyrrhotite and rare chalcopyrite in volcanics or along contacts with rhyolite dikes and 2) massive sulphide mineralization within gouge zones up to 1.9 meters wide consisting of pyrite, arsenopyrite and sphalerite and occasionally chalcopyrite and galena.

High gold and silver values are not coincident and do not appear to be associated with the percentage of sulphides present. The best mineralization is suggested to occur at or near the intersection of regional fault structures that trend 170 to 180 and 130 to 140 degrees.

In 1964, the G-South occurrence was held by Kerr Addison Gold Mines Limited as the J.J. group. A ground magnetic survey and E.M. profiles were completed on a, previously discovered, aeromagnetic anomaly.

In 1968 and 1969, Alrae Engineering Limited conducted soil geochemical and magnetometer surveys on the Thunder, Kim and Mike Claims. The exploration program included an area of 900 metres by 2100 metres and 516 soil samples. Later that year, 900 metres of diamond drilling was performed on two strong conductors. A shear zone was exposed at the time, with a width of 5.4 to 6.0 metres, and was found to coincide with magnetic and geochemical anomalies. A grab sample taken from a pit blasted in the shear zone was found, by assay, to contain trace gold, 26.8 grams per tonne silver and 0.27 per cent copper. A zone, approximately one foot wide, at the hangingwall of this shear zone contains galena, sphalerite, pyrite, pyrrhotite and chalcopyrite. A grab sample of this material assayed 4.8 grams per tonne gold and 74.7 grams per tonne silver (Property File Cyprus Anvil Cariboo Minelands Ltd. 1968).

Work by Alrae Engineering and Cariboo Minelands Limited identified massive sulphides (type 1 mineralization) partially exposed 10 metres to the southwest along the shear zone, which assayed 1.03 grams per tonne gold, 37.0 grams per tonne silver, 0.74 per cent copper and 0.08 per cent zinc across 0.45 metres. Another sample taken 37.5 metres further southwest along the zone across 0.3 metres assayed 2.06 grams per tonne gold, 22.3 grams per tonne silver, 0.38 per cent copper and 0.05 per cent zinc. A zone of copper mineralization (type 2 mineralization) in rhyolite was exposed during bulldozer trenching. Chalcopyrite and pyrite occur in veinlets up to 0.05 metres wide and in fracture fillings as stockwork veinlets within the rhyolite over widths of 0.30 to 0.60 metres. A grab sample of the stockwork mineralization assayed trace of gold, 53.5 grams per tonne silver and 3.51 per cent copper (Property File Cyprus Anvil, Cariboo Minelands Ltd., 1968).

A property visit and EM-16 survey was conducted later in 1968 by R. Kidd. The geophysical traverses found conductors at both known showings and three other conductors were located some distance to the west of the showings. Rusty andesite is exposed at one of these sites. In 1969, exploration on the property included geological mapping, magnetometer surveys, E.M. surveys, and diamond drilling totalling 900 metres over 8 holes.

Texas Gulf Sulphur acquired the property and completed geological mapping, magnetic and electromagnetic surveys, and soil geochemistry prior to relinquishing the option. Equatorial Resources (formerly Cariboo Minelands) drilled 5 percussion holes totalling 466 metres in 1972

The Discovery zone (type 2 mineralization), is exposed on the surface for 70m, is 1.2 to 1.5m wide and has been tested to a depth of 72 metres. Several new potential zones along the BL fault have been tested and one sample from drilling assayed 7.6 grams per tonne over 4.6 meters (Assessment Report 17309).

In 1981, the property was optioned from A.T. Syndicate by Gabriel Resources. During 1981 to 1985 ground geophysical and geochemical surveys and trenching were completed on the property. In 1986, work included an airborne magnetometer, electromagnetic, VLF-EM and an I.P. survey and 43 diamond drill holes (4704 metres). In 1987, a further 6,210 metres of percussion drilling was completed. In 1988, prospecting and heavy metal sampling was completed over adjacent sections of the property. Drill indicated reserves are 45,355 tonnes grading 10.2 grams per tonne gold (Gabriel Resources Inc. Annual Report, April 14, 1988). See Jo (093G 004) for details of Gabriel's work on the northern portion of its G claims.

In 1991, Valerie Gold Mines drilled three diamond-drill holes totalling approximately 300 metres (984 feet) on the property. Valerie had option the property from Appian Resources (formerly Gabriel Resources). The program was designed to re-test two previously drilled targets and drill test a significant geophysical anomaly. Of the two previously drilled targets, one was a gold intersection from a 1987 percussion hole and one was a copper/gold intersection. The hole was collared approximately 500 metres northwest of a massive sulphide showing identified in previous programs. Hole 91-1 intersected a rhythmically banded sequence of andesite, dacite, and sediments. Sulphides tended to be concentrated in the dacite units. Gold mineralization was encountered in several zones within the drill core. The highest value was from a 0.46 grams per tonne gold silicified dacite-fragmental which returned 5.49 grams per tonne gold and 1.4 per cent Cu. A 6 metre intersection averaging 0.69 grams per tonne gold in the upper portions of another dacite sequence and a sheared porphyry dike in the bottom 3 metres of the hole which ran 0.79 gram per tonne gold (Assessment Report 21740).

Doublestar Resources Ltd. acquired an interest in the property in 1998.

During 2000, a Self Potential Survey was performed by prospector Dave Javorsky on the G-South. The object of the Self Potential Survey was to relocate the old “Discovery Showing” and to see if the mineralization would show a Self Potential signature. It was found that original massive showings had been covered up, the trenches filled in and topsoil pushed over the outcrop exposures. The Self Potential survey was reported to work well enough to outline the dimensions of the old “G-South Discovery Zone”.

In 2006, Richfield Ventures Corp conducted a small prospecting program on is claims which cover the G-South occurrence.
