The Columbian claims are located on the north side of Summit Creek, approximately14.5 kilometres north west of Creston. From 2003 to 2005, the claims were explored as a part of the Kootenay Gemstone property of Cream Minerals Ltd., including the Laib Creek, Rusty and Cultus showings to the north.
The area is underlain by granites and granodiorites of the middle Cretaceous Bayonne Batholith (Shaw Creek stock) and sediments of the La France Group. Pegmatites cut all rock types and host beryl crystals.
Locally, 1 to 1.5 metre wide pegmatite sills are hosted in high metamorphic grade garnet-biotite-muscovite schists. Light bluish-white and yellowish white, opaque beryls are the most common, while translucent beryl crystals up to 5 centimetres long are noted (Assessment Report 27850).
