The TCS property is underlain by the same Kutcho Formation rocks as found in the vicinity of the mineralized deposits at the Kutcho property. These include crystal bearing felsic volcanic rocks and aphyric felsic tuffs that may represent the same mineralized time horizon as at Kutcho. Alteration and mineralization at TCS consists of silica-sericite-pyrite alteration of felsic volcanic units with weakly anomalous geochemistry. Historic soil sampling defines a 600 m by 800 m Cu-Zn anomaly (Figure 2) and is largely limited only by the presence of glacio-lacustrine deposits.

Chalcopyrite mineralization has been discovered in chlorite altered rocks that could be footwall stringer style mineralization to a VMS deposit or mineralization hosted in mafic volcanic rocks (Figure 3). Additionally, a coarse felsic fragmental/breccia unit has been encountered at TCS suggesting the possibility of being vent proximal in the volcanic environment.
