Geology:
In the Thunder Creek area mineralization occurs in two main stages: a) the Rusk Shear Zone adjacent to and in footwall or the pyroxenite unit, and b) in the Porphyry Zone which is hosted by the quartz monzonite intrusion which is present southeast of and in the immediate footwall to the Rusk Shear Zone below approximately 500m below surface. Both of these zones occur spatially related in the same steep north-northwest plunging mineralization area which has been traced over a vertical dip length to date of more than 1 km, and within which better intercepts occur along a strike length of 100 to 600m. Mineralization in the Rusk Shear Zone comprises areas of either a) higher quartz-carbonate-pyrite vein density, and or b) areas of elevated medium to coarse-grained disseminated pyrite and associated pyrite-quartz veinlets. Both of these styles were observed to occur in the intensely foliated, often compositionally laminated carbonate-albite-quartz-magnetite portions of the shear zone. Mineralization also locally preferentially overprints pink, K-feldspar-rich syenite dykes and local plagioclase-dominant probable diorite dykes in the shear zone, with clots and aggregates of coarse pyrite, often associated with which quartz-albite-carbonate veinlets. Areas of gold mineralization occur in portions of the Rusk Shear Zone in which the shear zone matrix is variably Fe-carbonate altered.
