The Red Eagle workings are hosted by the Lower Jurassic Rossland Group (Elise Formation) augite porphyry, known as the Rossland sill. The porphyry is dark green with phenocrysts of dark augite which are partly altered to hornblende. The rock is commonly brecciated with preferential epidote alteration. The Early Jurassic Rossland monzon- ite stock intrudes the Rossland Group rocks and the Red Eagle claim lies within the zone of thermal metamorphism.

The mineralogy of the Red Eagle occurrence has not been reported but mineralization is considered a South Belt-type which typically contains pyrite, pyrrhotite, arsenopyrite, galena, sphalerite and locally, boulangerite in a gangue of sericitized wallrock, quartz and carbonate (Bulletin 74, page 39,40). In 1908 and 1927, 7 tonnes of ore were mined from which was recovered 4,603 grams of silver, 60 kilograms of copper, 381 kilograms of lead and 15 kilograms of zinc.
