The Garnet occurrence, composed of finely disseminated bornite in a fine-grained feldspar porphyry over a 4.58 metre width, is located 4.75 kilometres north of Toodoggone Lake and west of Jack Lee Creek. The showing is in the south-central part of the Toodoggone Gold Camp, roughly 280 kilometres north of Smithers.

The Garnet showing is situated within a Mesozoic volcanic arc assemblage which lies along the eastern margin of the Intermontane Belt, a northwest-trending belt of Paleozoic to Tertiary sediments, volcanics and intrusions bounded to the east by the Omineca Belt and to the west and southwest by the Sustut and Bowser basins.

Permian Asitka Group crystalline limestones are the oldest rocks exposed in the region. They are commonly in thrust contact with Upper Triassic Takla Group andesite flows and pyroclastic rocks. Takla volcanics have been intruded by the granodiorite to quartz monzonite Black Lake Suite of Early Jurassic age and are in turn unconformably overlain by or faulted against Lower Jurassic calcalkaline volcanics of the Toodoggone Formation (Hazelton Group).

The dominant structures in the area are steeply dipping faults which define a prominent regional northwest structural fabric trending 140 to 170 degrees. In turn, high angle, northeast-striking faults (approximately 060 degrees) appear to truncate and displace northwest-striking faults. Collectively these faults form a boundary for variably rotated and tilted blocks underlain by monoclinal strata.

The showing is hosted in feldspar porphyry. On a regional scale, the Toodoggone Formation at this location is undifferentiated and described as well bedded lapilli tuff and pyroclastic breccia, porphyritic andesite, subordinate basalt lava flows, volcanic conglomerate, siltstone, and mudstone (Bulletin 86).

On a local (property) scale, other rock types evident in the vicinity are fine-grained, dense, dark grey to purple andesite or basalt, fine-grained, dense, siliceous rhyolite (usually found as dikes), and medium to coarse-grained hornblende monzonite. Generally, the rocks are well fractured and variously altered. Fractures are commonly filled with epidote, serpentine and criss-crossing calcite veinlets. Faults are prominently exposed in cliff walls and along ridges. Two main fault systems and associated fractured rock trend northeast and northwest with near vertical dips (Assessment Report 1805).

In 1968, a selected grab sample from the Garnet 12 claim contained finely disseminated bornite hosted in fine-grained feldspar porphyry over a 4.58 metre width and extending vertically. The sample analyzed 0.42 per cent copper and 9.93 grams per tonne silver (Assessment Report 1805).

In 1968, geological mapping and prospecting was conducted on the Garnet claim group on behalf of Quebec Cartier Mining Company.

In 1981 and 1982, Du Pont of Canada Exploration Ltd. completed programs of geological mapping and geochemical (rock, silt and soil) sampling on the area immediately to the southwest as the To 1 claim.

In 1986, Toodoggone Gold Inc. completed a 380 line-kilometre airborne geophysical survey on the area as the Mul 1-4 claims.

In 2004 and 2005, Stealth Minerals Ltd. completed programs of prospecting, geological mapping and geochemical (rock, silt, and soil) sampling on the area as a part of the Gordo-Too-Oxide property.

In 2004, numerous mineralized float samples from the Garnet occurrence area, extending from approximately 3 kilometres to the southwest on Estabrook Creek to approximately 3.5 kilometres to the northwest along a north-northwest–trending ridge, yielded values of up to 0.723 gram per tonne gold, 29.8 grams per tonne silver, 0.991 per cent lead and greater than 1.00 per cent each of copper and zinc (Assessment Report 27638).

The following year, a float sample (64640) of banded quartz-carbonate veining with chalcopyrite, pyrite and hematite in andesite flows, located to the southwest, assayed 11.60 grams per tonne gold, 39.2 grams per tonne silver and 0.315 per cent copper (Assessment Report 28039). Also at this time, a chip sample (64651) over 0.4 metre of fractured outcrop with quartz veining and minor chalcopyrite, located on a ridge approximately 3 kilometres to the north-northwest, assayed 0.260 gram per tonne gold, 22.9 grams per tonne silver and 0.469 per cent copper (Assessment Report 28039).
