The Hemmingsen West occurrence is located on a ridge over looking Hemmingsen Creek, at approximately 900 metres elevation.

The area is underlain by a series of basaltic flows and related pyroclastics of the Karmutsen Formation and is overlain by, or interbedded with, limestone of the Quatsino Formation; both formations belong to the Upper Triassic Vancouver Group. Andesite to rhyolite tuffs and breccias, with minor intercalated greywacke and argillite, of the Lower Jurassic Bonanza Group overlie the Upper Triassic rocks. Intruding this stratigraphic assemblage is the Early to Middle Jurassic Island Plutonic Suite of monzonite to diorite composition.

Locally, an area of skarn or ‘iron formation’ hosts sulphide mineralization. Sulphides are described as primarily magnetite, pyrite and chalcopyrite. Hematite and serpentine are also reported in the area.

In 2007 through 2009, Le Baron Prospecting completed a program of prospecting on the area as the Hemmingsen Creek project (claim 535899). In 2008, a sample (H031051) of ‘iron formation’ hosting sulphides assayed 4.6 grams per tonne silver and 0.969 per cent copper (Assessment Report 30515). In 2010, rock chip samples (H031029 through H031036) of oxidized sulphides assayed from 43.8 to greater than 50.0 per cent iron with up to 0.671 per cent copper and 1.56 grams per tonne silver (Assessment Report 31291).
