The Sowaqua Shear occurrence is located on Sowaqua Creek, approximately 500 metres southeast of its confluence with Rice Creek.

The Hozameen fault traverses south-southeast across the area, separating the greenschist facies rocks of the Permian-Jurassic Hozameen Complex from unmetamorphosed Mesozoic rocks of the Ladner and Dewdney Creek groups. Ultramafic rocks occur along the Hozameen fault and these are part of the Coquihalla Serpentine Belt.

Locally, a shear zone occurs in argillite with iron-carbonate lenses. The argillites are in contact with brecciated lithic-greywacke and serpentine. A quartz lens within the shear hosts chalcopyrite and molybdenite, while the adjacent cherts and cherty argillites host minor disseminated pyrrhotite. In 1984, samples from the shear assayed up to 1.04 grams per tonne gold and 0.1 per cent arsenic (Assessment Report 14751).

The area was reported first explored in the early 1930’s and some minor trenching was performed during this time on the nearby Big Range (MINFILE 092HSW145) occurrence. During 1984 through 1986, Caara Ventures completed programs of prospecting, geochemical sampling and 15.4 line-kilometres of combined ground electromagnetic and magnetic surveys on the area as the Big Range claims. In 2008 and 2009, the area was prospected as the Master 1 property. In 2012, Savoy Ventures completed a 412.0 line-kilometre airborne electromagnetic survey on the area.
