The DCP showing on the Trek property is underlain by Upper Triassic Stuhini Group rocks, which have been intruded by Late Triassic to Early Jurassic 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.

Follow-up of conductors and magnetic highs identified in the 2007 Fugro Airborne geophysical survey led to the discovery of the DCP zone in 2008 by Romios Gold Resources.

The DCP showing is located within mafic volcanic rocks dominated by basalt and lesser volcaniclastics, flow breccias and marine sedimentary sequences. Molybdenite mineralization is seen over an approximately 100 by 100 metres area in quartz veins plus/minus chalcopyrite and rare muscovite. Veins rarely exceed 1 centimetre in width, and vein density is low. This area is adjacent to a large Eocene monzonitic intrusion, which is known to be associated with molybdenum and base metal mineralization. A small magnetic high hidden below the toe of the glacier is also likely a smaller Eocene stock. Eocene monzonite dikes are seen cutting mafic volcanics. Copper mineralization is seen over an approximately 200 by 200 metres area as malachite staining on fractures, as rare chalcopyrite clots associated with epidote alteration, or less commonly as malachite infill of vesicles within the basaltic flows. Alteration is characterized by epidote, quartz-pyrite, calcite and rare potassium feldspar veins, and chalcopyrite-pyrite mineralization seems most common in quartz plus/minus calcite plus/minus epidote veins. Secondary biotite and sericite were noted locally.

Sample 686961 assayed 5.27 grams per tonne gold, 22.8 grams per tonne silver and 3 per cent copper (Assessment Report 30748).
