The Toe zone of the Trek property is underlain by Upper Triassic Stuhini Group rocks, which have been intruded by Late Triassic monzonitic intrusions, Eocene granitic dikes, sills and stocks and Miocene basaltic and rhyolitic dikes. Mineralization on the property is dominated by copper-gold bearing porphyry and porphyry-related disseminated, vein-controlled and breccia hosted mineralization.

The Toe Zone showing is exposed on the east side of Trek Creek near the toe of the existing glacier in the Trek Creek. It is hosted in variably altered fine-grained andesitic tuff with rare feldspar and augite crystals. Discontinuous, well-banded and poorly banded steeply dipping sulphide lenses up to three meters wide are conformable with the bedded volcaniclastic rocks. Pyrite clots with rare jasper are interpreted as clastic fragments. Alteration is characterized by pyrite-sericite-silica. The alteration zone may be up to eight meters wide, is highly irregular and largely diffusing outwards from prominent fractures.

The massive and semi-massive sulphide zones are characterized by variably banded/layered pyrite, chalcopyrite, sphalerite, galena and barite. Previously this showing has been interpreted to represent Kuroko-type volcanogenic massive sulphide mineralization. Work from the 2006 exploration program did not confirm or deny this interpretation.
