The Rusty claims are located on the western flank of Mount Burnett Mountain, approximately 1.5 kilometres south of Cultus Creek. From 2003 to 2005, the claims were explored as a part of the Kootenay Gemstone property of Cream Minerals Ltd., including the Laib Creek 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, two significant beryl showings have been located within the Rusty claims (Assessment Report 27850).

The original showing, known as the Rusty showing, is located approximately 3 kilometres south of the Cultus showings. It is characterized by trace amounts of blue, opaque, subhedral beryl and trace pyrite in simple, narrow quartz-feldspar pegmatite veins oriented 048/44SE.

The second showing, also known as the Jarrod’s showing, is located approximately 2 kilometres south of the Cultus showings. It is characterized by a sparse swarm of fine- grained pegmatite veins and narrow dikes, containing 90 per cent feldspar, 8 per cent grey quartz, and minor muscovite, hosted in a K-feldspar–phyric quartz monzonite. Rare to occasional beryls occur as white to blue, opaque to translucent, euhedral crystals up to 1.5 centimetres in diameter.
