Dec 16, 2010 (A Wilson) - Diamond drilling intersected a sequence of pink and grey quartzite to argillite. The quartzite is described as being well-bedded and slightly arkosic in sections. The quartzite is intruded by a 20 foot thick diabase dike at about the 73 foot level.

Dec 16, 2010 (A Wilson) - Disseminated chalcopyrite and pyrite is found scattered throughout the quartzite. Some narrow mineralized stringers also were observed adjacent to what is interpreted to be a shear zone. A 4.7 foot section of core from DDH R-1 returned 0.10% Cu. A 3.2 foot section of bornite-bearing core from DDH R-5 returned 0.16% Cu.
