The Cultus claims are located on Cultus Creek, approximately 2.3 kilometres from its junction with Laib 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 Rusty showing, to the north and south, respectively.

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, bluffs include K-feldspar– phyric quartz monzonite, and minor veins and dikes of aplite, equigranular granite, and pegmatite. Beryl crystals occur in the pegmatites as light blue, opaque to translucent euhedral crystals hosted in simple, centimetre to tens of centimetres wide K-feldspar quartz (±smokey) pegmatitic dikes and veins (Assessment Report 27850).

In 2003, two locations on the Cultus and OMG claims were identified containing, 10 to 30 centimetre wide, quartz veins that extend out of the quartz cores, through the host coarse-grained pegmatite, and into surrounding aplite and/or sedimentary rock types. These veins are 90% light-grey to smokey quartz with subordinate K-feldspar, trace beryl and molybdenite, and up to 5 per cent vugs, lined with rimes of very fine- grained micas and/or clays, and occasionally beryl crystals. Several gemmy ice-blue, translucent to transparent, euhedral aquamarine crystals, to 6 millimetres in diameter, have been found in this vein type. Molybdenite occurs as sparse, yet coarse disseminations up to 1.5 centimetres. Smokey quartz is most prevalent in and around vuggy sections of the veins (Assessment Report 27478).
