The Kitgold occurrence is located 16.1 kilometres north of Alice Arm, 2.6 kilometres west of the Kitsault River and 1.9 kilometres south of Lyall Creek at approximately 1200 metres elevation. The region is underlain by an assemblage of volcanic and sedimentary rocks comprising the Upper Triassic Stuhini Group and the Lower Jurassic Hazelton Group.

The Kitgold occurrence is underlain by fine to medium grained, interbedded andesitic lapilli tuff to tuff breccia with intercalated maroon porphyritic and amygdaloidal volcanic rocks, sandstone and siltstone that form a northwest trending anticline. Pillowed basaltic flows, conglomerates and pillow breccia, with small lenses of interbedded siltstones and limestone, lie in the core of the anticline and form a northwest striking band 0.5 to 1.5 kilometres wide through the centre of the area. Approximately 800 metres to the east of the main aniticline, a less prominent subparallel syncline occurs.

Faults and shears within the area are predominantly oriented north to northeast. A series of fine to medium grained subvolcanic dikes of intermediate composition, up to 10 metres wide, generally trend northwest parallel to subparallel with the fold axis and stratigraphy.

Quartz veining is concentrated along a north trending linear zone, 10 to 30 metres wide and 1000 metres long. Veins within the zone may be up to 2 metres thick and several hundred metres in length. These large veins also give rise to ubiquitous veinlets and stringers between individual veins. Crosscutting relationships indicate at least three phases of emplacement, resulting in a high degree of brecciation and silicification associated with a well developed elaborate stockwork. Sericitic and limonitic alteration exists but is localized and weakly developed. The veining occurs within a massive intermediate volcanic flow. Sulphide mineralization occurs mostly as pyrite, up to 20 per cent in veins, and associated wallrock contacts. Rare arsenopyrite and/or chalcopyrite is associated with pyrite.

Rock samples taken from the hangingwall of the main quartz vein system, on the eastern side of the property, in the vicinity of the syncline, yielded five samples that assayed greater than 3.4 grams per tonne gold. The main quartz vein system did not yield any significant values (Assessment Report 21173). Approximately 750 metres to the west, an old trench exposes a brecciated quartz vein system hosted within interbedded tuff and siltstone. The quartz vein, which parallels bedding (022 degrees strike and 60 degrees east dip), contains up to 25 per cent reddish brown sphalerite. Approximately 2 kilometres to the southwest a sample taken of from an ankeritic quartz vein cutting andesite assayed 0.62 gram per tonne gold, 0.27 per cent lead and 0.07 per cent zinc (Assessment Report 21173).

In 2005, Kitsault Resources Ltd. completed a reconnaissance stream sediment survey on the area as the Kitsault Gold property.
