The Cob claim lies at the southeast extremity of the Late Triassic-Early Jurassic Iron Mask batholith in contact with Upper Triassic Nicola Group volcanics to the east. Outcrop is scarce on the property. Four lithologic units have been recognized and comprise fine to medium grained augite diorite (Sugarloaf unit), diorite breccia (Iron Mask Hybrid unit), leucocratic microdiorite (Cherry Creek unit) and picrite (Picrite unit). The easternmost part of the batholith on the property is strongly fractured and locally sheared. Malachite and pyrite occurs in sheared and brecciated Cherry Creek unit diorite in the northwest corner of the claim. A trace of malachite was noted in picrite in the southeast part of the property, 1500 metres south-southeast of the first showing.

In 1989, a short program of geological mapping and soil sampling (44) was conducted on the Cob claim by J.E. Christoffersen.
