The Topaz claims are located near the junction of Topaz and Summit creeks. 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, beryl occurs as subhedral to euhedral, white, opaque crystals hosted in pegmatite sills and dikes. Pegmatite mineralogy consists of feldspar with significant quartz and muscovite, occasional red garnet and black tourmaline, and trace white to yellow and rarely pale blue beryl.

In 2005, white opaque beryls, 1 to 3 centimetres wide, were also found on a 50 by 100 metre bluff comprising pegmatitic granite and subordinate fine- to medium- grained pegmatite. Quartz-illmenite veins occur locally along the margins of the pegmatoid units (Assessment Report 27850).
