Lithology Comments

Jan 23, 2013 (A Wilson) - In general terms, a footwall predominantly komatiitic sequence is separated from a thick predominantly tholeiitic sequence of variably altered massive and pillowed, meta-basalt flows by a thin cherty marker horizon. The cherty marker horizon is anchored in the southern parts of the deformation zone which passes west to west-northwest through Lindberg Lake. Disruptions in the stratigraphy occur in several areas due to intrusive rocks, notably a gabbrodiorite complex at greater than 750 m depth in the QK Zone area and west. The stratigraphy has subvertical to steep north dips with local steep south dips near the footwall contact. Possible tight isoclinal folding is suggested by the repetition of some stratigraphic units in the hangingwall sequence. Some of the most intense deformation is centred on the hangingwall-footwall contact area. A district flexure has developed within the hangingwall of the Main Zone at the mine, with 40º-45º west plunge above the 560 m level which shallows with depth. Another may occur beneath the QK Zone to the west; however, significant (fault) imbrication is also suggested. The Main Zone structure was formed in a shearing regime due to the displacement along the contact between footwall komatiites and hangingwall tholeiitic basalt flows

Mineralization Comments

Jan 23, 2013 (A Wilson) - The best assay from drill hole 436-007 returned 0.91 g/t Au over 1.98, within 5.05 m interval averaging 0.46 g/t Au. About 600 m west, drill hole G-83-9 (General Energy) reportedly returned an assay of 5000g/t Au over 0.12 m. The gold mineralization is commonly, but not exclusively, associated with the biotite altered rocks. These observations suggest the biotite alteration occurred during pre-peak metamorphism, indicating syn-volcanic hydrothermal alteration. There is a correlation of gold grade versus the presence of K-spar alteration. High sulphide concentrations are associated with many of the zones and include fracture controlled, vein and disseminated pyrite, pyrrhotite and chalcopyrite (local sphalerite). Visible gold is quite common, generally fine grained and locally accompanied by tellurides in quartz veins. Visible gold also occurs in some fractures in felsic dykes and CG units without quartz. Gold mineralization is commonly spatially related to brown biotite and/or potassic feldspar (potassic alteration) and locally to sericitic-muscovite alteration in Main Zone and felsic dyke settings.
