The McClair 3 showing consists of a mineralized diabase to diorite dike hosted in granodiorite stock, exposed on a northwest- trending ridge 6.3 kilometres northeast of Kadah Lake and 3.5 kilometres northwest of the confluence of McClair Creek and the Toodoggone River (Assessment Report 9995). The showing is 300 kilometres north of Smithers. It lies within the Omineca-Cassiar mountains in the north-central portion of the Toodoggone gold camp.

The McClair 3 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. These Takla rocks have been intruded by plutons and other bodies of the mainly granodiorite to quartz monzonite Early Jurassic Black Lake Suite 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 McClair 3 showing is dominantly underlain by a monzodiorite to granodiorite stock (Assessment Report 9995 and Bulletin 86). Within this stock a complex series of dikes ranging from diabase to diorite and dacite, with similar textural variations, occurs. They are locally altered and frequently contain quartz and carbonate veins with minor pyrite and traces of other sulphides (Assessment Report 9995).

Alteration of this stock occurs mainly as veins. Minor zones of quartz-sericite alteration is also present. Quartz (+/- carbonate and epidote) veins and stockworks cut the hostrock irregularly and host mineralization (Assessment Report 9995). The veins are clear to milky and occasionally display vuggy and drusy textures. Generally less than 10 per cent of the rock is vein material but locally up to 40 per cent. Pyrite is the dominant sulphide, comprising 5 per cent or less of sulphides. Chalcopyrite and sphalerite comprise 1 per cent or more and galena roughly 2 per cent (Assessment Report 9995). All occur as disseminations, either fine grained or as blebs.

In 1981, Asample 71001, taken from a diabase to diorite dike hosted in the stock, analysed 2.8 grams per tonne silver, 0.8 per cent lead and 0.525 per cent zinc (Assessment Report 9995). A second sample taken 250 metres lower in the creek gully, analysed 2.7 grams per tonne silver and 0.618 per cent lead (Assessment Report 9995).

Also in 1981, a sample (61385) from an area of quartz-sericite-calcite-pyrite veining, located approximately 400 metres to the northeast, yielded 2.16 grams per tonne gold, whereas four samples (61395, 61397, 61400 and 61401) of quartz-epidote-chalcopyrite-bornite, taken along the ridge to the northwest, yielded from 0.450 to 1.720 per cent copper with up to 9.0 grams per tonne silver (Assessment Report 9995).

In 2018, a grab sample (100427) of andesite with malachite, azurite, chalcopyrite and galena, located approximately 750 metres to the northeast, assayed 0.701 per cent copper and 10.9 grams per tonne silver (Assessment Report 38203).
