The A & W occurrence is located on the south western side of Sowaqua Creek, approximately 900 metres east south- east of the mouth of Colville Creek.
The area is underlain by Permian to Jurassic Hozameen Complex rocks comprised mainly of interbedded chert, pelite and volcanic sandstones with distinct grey and black banding. The pelite is dark green and chloritized, with traces of calcareous and weakly hematitic bands. Minor quartz veinlets and secondary pyrite veinlets crosscut these metasediments.
The Hozameen Complex is intruded by sill-like bodies of quartz diorite that are weakly foliated. The Hozameen fault traverses south-southeast, separating the lower greenschist facies rocks of the Hozameen Complex from un-metamorphosed Mesozoic rocks to the east. Ultramafic rocks are cut by greenstones of the Hozameen Complex, which generally occur along this fault. There is extensive shearing along the contact and in places the ultramafics appear to be intrusive. The ultramafic rocks which occur along the Hozameen fault are part of the Coquihalla Serpentine Belt.
In 1980, samples were collected from a highly altered pelite close to a serpentinized intrusion. The intrusion is described as having a granitic texture with chlorite and soft talc with clusters of radiating andalusite crystals. The pelite hosts secondary quartz and pyrite veinlets. Also, intense limonitic staining occurs adjacent to the intrusion. A grab sample from the pelite assayed 0.34 gram per tonne gold (Assessment Report 9581).
Drilling in 1983 indicated short intervals of chlorite-silica-pyrrhotite in the black argillite, which hosts disseminated to massive pyrrhotite. The argillite also contains quartz stringers with disseminated pyrrhotite. The pyrrhotite-rich sections in the argillite are oxidized and are associated with limonite and hematite. Thirty-three samples containing silica with visible pyrrhotite and pyrite were assayed. Assays yielded traces of gold, silver, copper and nickel (Assessment Report 11449).
During 1979 through 1984, Aquarius Resources completed programs of soil and rock sampling on the area as the Jessi claims. In 1980 and 1983, Altar Gold and Resources completed programs of soil and rock sampling, geological mapping and a 15.6 line-kilometre ground magnetic survey. In 2000 and 2001, Hillsbar Gold completed a program of prospecting and geological mapping on the area as the Plat 3 and 4 claims. During 2008 through 2012, Almo Capital completed programs of rock and soil sampling on the area as the Serp 5 and 6 claims. In 2012, New Caroline Gold completed 434.4 line-kilometres of combined electromagnetic, magnetic and radiometric airborne geophysical surveys on the area.
