Dec 07, 2005 (D Guidon) - Northeast-striking Watabeag Assemblage is wedged between and intruded by Watabeag Batholith granitic rocks to the north and Cairo stock syenitic rocks to the south. Huronian Cobalt Group sediments overlie the Archean rocks immediately to the east. The Larder Lake Fault Zone, which is covered by the Cobalt Group sediments, is interpreted to trend in a southwesterly direction about 2 km south of the claim.

Dec 07, 2005 (D Guidon) - Mafic pillowed flows and intercalated massive mafic volcanic rocks are found in the area. Some minro bands of interflow sedimentary rocks, tuffs and cherts are developed. The sequence is intruded by syenite dikes northeast of the showing.
