Jan 14, 2015 (A Wilson) - Gold mineralization occurs conformably within a sequence of Deloro Assemblage tuffs, tuff breccias and agglomerates sandwiched between 15 to 30 m thick units of fine-grained ultramafic flows. Gold mineralization occurs as a series of high-grade shoots within a zone up to 15 m thick and over a strike length of 470 m and to a depth of 200 m. The mineralized zone consists of pale green, quartz-chlorite-ankerite-sericite schist that is an altered felsic tuff with volcanic fragments. Two stages of quartz veins are found within the zone.

Jan 14, 2015 (A Wilson) - Samples of drill core collected in 1935 returned values of $23.75 over 18 inches, $232.50 over 9 inches and 3.78 over 5 feet. In 1986, Wabigoon Resources reported that the primary gold zone had been intersected in 7 dril holes at a depth of 150 m over a length of 285 m with an average cut gold grade of 10.3 g/t Au.
