The Dionne showing is located near Sugar Lake on the south side of Sprockton Creek, about 37 kilometres northeast of Lumby.

In 1992, a prospecting and sampling program was conducted on the Dionne claim.

The area is underlain by metamorphic rocks of the Proterozoic to Paleozoic Kootenay Assemblage. These comprise gneiss, schist, pegmatite, quartzite and marble.

An outcrop contains pegmatite bands and a siliceous rock unit in gneiss. The siliceous material contains fine pyrrhotite and lesser amounts of pyrite or chalcopyrite. Assay values from a rock chip sample of this outcrop were low in base and precious metals (Assessment Report 22524). The pegmatite contains books of muscovite up to about 1 centimetre in size.
