Dec 07, 2005 (K R Kettles) - The property is underlain by mafic to felsic metavolcanic flows and pyroclastics. The units strike E-W and dip steeply to the north. Thin quartz feldspar porphyry dikes intrude the volcanic rocks, and are parallel to sub-parallel to the metavolcanics. The metavolcanics are bounded to the north and south by large granitic intrusions. Mineralization occurs in a shear zone in mafic volcanic rocks. The sulphide-rich zone is 6 m wide and dips steeply to the north.

Dec 07, 2005 (K R Kettles) - The mafic metavolcanics are mainly flows, while the felsic metavolcanics are pyroclastics. The mafic volcanics which host the deposit are sheared and biotitic. Sulphides are disseminated in the mafic volcanics, as well as in stringers. Large granitic intrusions bound the metavolcanics to the north and south.

Dec 07, 2005 (K R Kettles) - A highly sheared to schistose unit of biotitic mafic metavolcanics hosts the deposit. Sulphide mineralization consists of narrow stringers and blebs of pyrrhotite, minor pyrite and variable amounts of chalcopyrite. A section from 2 drill holes indicates the sulphide-rich zone is about 6 m wide, and dips steeply north. A good zone of conductivity with magnetic correlation represents the sulphide zone intersected by diamond drilling. The following results were obtained from the 1976 drill program: DDH 220-1-1: AT 43.31 m: 0.03 OPT AU, 0.04 OPT AG, 0.98% CU over 3.36 m. 1976 DDH 220-1-1: at 43.31 m: 0.03 opt Au, 0.04 opt Ag, 0.98% Cu over 3.36 m. 1976 DDH 220-1-2: 4 intersections: best at 90.92 m: 0.013 opt Au, 0.07 opt Ag, 1.06% Cu. 1945: 5 veins identified, best assay 0.24 opt Au (Vein #2 – 480 m w of Selco DDH).( from the original MDI).
Dec 07, 2005 (K R Kettles) - The mafic volcanics which host the Rogard occurrence are highly sheared, bioititic, and sulphide rich. This zone strikes almost parallel to the volcanics at E-W, and dips steeply north.
