The Comego showing is located on the Widow claims about 6.5 kilometres north of Youbou at the headwaters of Chemainus River.

Skarns are developed in the Mississippian to Pennslvanian Fourth Lake Formation (Buttle Lake Group) sediments which have been intruded by Triassic diabase and gabbro sills informally called the Mount Hall gabbro. Mineralization may, however, be related to the nearby Jurassic Reynard Creek diorite stock. The rock types in the area comprise chert, cherty tuffs and sediments, agglomerates and argillites.

Mineralization consists of chalcopyrite, pyrite, pyrrhotite, magnetite, minor molybdenite, sphalerite, tetrahedrite, rare bornite and arsenopyrite. Pyritiferous quartz- carbonate altered shear zones outcrop in the Chemainus River south of the areas of skarn mineralization. Assays from the quartz-carbonate zones are very low. Mineralization occurs as three types: 1) Quartz-calcite-garnet- actinolite skarn with magnetite, chalcopyrite, pyrrhotite, pyrite and locally tetrahedrite replacing sediments 2) Quartz veins hosting molybdenite, pyrite and chalcopyrite; and 3) quartz-carbonate veins in shear zones.

The claims were originally staked in 1902 as the Cascade claim. Considerable exploration has been done on the property including five short tunnels and numerous trenches. In 1963, the Comego claims were explored by a program of geochemical sampling, geological mapping trenching and two diamond drill holes. Grab samples assayed up to 8.9 grams per tonne gold, 27.4 grams per tonne silver, 1.3 per cent molybdenum and 8.3 per cent copper (Assessment Report 641).

In 1969 and 1970, Hibernia Minerals claimed the area as the Anne claim and completed programs of soil geochemical sampling, geological mapping and a ground electromagnetic survey. In 1981, New Gold Inc. completed a program of geological mapping and prospecting in the area as the Sherk and Widow claims. In 1984 and 1985, Imperial Metals Corp. completed a program of soil geochemical sampling and a ground electromagnetic survey on the area as the Whymp 1-2 claims.

In 1990 and 1994, New Gold Inc. completed programs of geological mapping and a ground geophysical surveys on the area as the Widow 3-8 claims. In 2008, Cuda Capital Corp. completed a program of helicopter-borne magnetic and VTEM surveys on the area as apart of the El Capitan Property.
