5 CO-20 Mineral occurrences Volcanogenic massive sulphide Cu-Zn bimodal mafic - mafic to felsic metavolcanics intruded by gabbro - Mineralization traced in outcrop / frost heave over 200 m strike length - drilling intersected stringer py, po, and cpy, biotite, po - talc and chloritealtered intermediate tuffs and mafic to intermediate flows in the hangingwall - massive py, po, cpy, and sph in the footwall biotite-talc-amphibolechlorite altered mafic to intermediate tuffs - stringer overlying massive and Cu overlying Zn suggests the stratigraphy may overturned with tops to the east 4.0% Cu, 4.34% Zn / 1.56 m in ddh 5

6 CO-20 Geology underlain predominantly by the Eastern domain - High Lake belt - south- and east-facing basalt overlain by intermediate fragmentals and flows with lesser felsic volcanics - gabbro-diorite occur as conformable thin lenses and bodies within mafic volcanics - moderately to strongly magnetic phase that postdates an earlier non-magnetic phase - greywacke to mudstone, and amph-gt Fe-formation top the volcanics to the south rocks of the Central domain underlie the northwest corner - mafic volcanic flows, sills, dykes and breccias - metasedimentary rocks consist of graded greywacke to mudstone turbidite successions Butane Fault displays several hundreds of metres of sinistral displacement The Plumbob break separates the Eastern and Central domains 6

7 CO-20 Fire-Match-Smoke underlain by a sequence of NE-striking mafic flows locally interbedded with intermediate to felsic volcaniclastics, all intruded by gabbro sills Bedrock exposure - poor to moderate mineralization is associated with o, steeply dipping, chlorite-carbonatesericite altered shear zones parallel to oblique to stratigraphy Fire shearing in mt-bearing pyroxenite gabbro Altn appear to be limited to local chloritization and carbonatization, with patchy silicification Match - mtc or non-mtc gabbro/diorite or qtz veins hosting finely disseminated py, po, and cpy along vein-host rock or volcanic contacts Altn commonly silica flooding and carbonatization Smoke -poorly exposed sulphide-bearing veins localized along narrow, sheared felsic flow in contact with mafic volcanics disseminations or bands of py and cpy comprising up to 3% of the vein 7

9 CO-20 Fire-Match-Smoke Mineral deposit model: - giant Kalgoorlie gold deposit - Kalgoorlie Superpit - 652,000 oz Au produced in ,964,000 oz reserve in 2014 ( - the most important gold host is the Golden Mile Dolerite (80% of gold produced) - tholeiitic gabbro sill intruded between a lower mafic-ultramafic volcanics and overlying felsic rocks and metasediments - ductile shear zones related to folding are the site of most economic gold mineralization (Phillips, 1986) - fluids react with gabbro depositing gold 9

10 CO Geophysics Targeted the nature of the rocks hosting gold and the associated sulphides - in mt-bearing pyroxenite gabbro (Fire) - in and along felsic volcanics contacts (Smoke) - Stringers, semi-massive to disseminated pyrite, pyrrhotite, chalcopyrite, and sphalerite magnetic response traces the magnetic gabbro sills suggests continuity through areas with little outcrop highlights sills parallel to known gold zones that have not been investigated (pass work has been guided by surface sampling) Aids in defining structures that disrupt the stratigraphy but have not been explored 10

11 CO Geophysics EM has no obvious correlation with the gold other than possibly in the Smoke - there is mention of po and py in core - correlating with the gold in one hole but not two others associated with the northern anomaly. best EM conductor is overburden covered and unexplained - No Lake gossan - 15 by 50 ft. mt-cpy in by chloritic rhyolite returned 2.19% Cu - U4 gossan: small blocks and stringers of po with minor cpy hosted by highly siliceous volcanic rocks returned up to 0.20% Cu and 1.20% Zn. - may be a good VMS target anomaly south of No Lake is also overburden covered - volcanic hosted? Spot anomaly - disseminated to massive py and po with best result 0.94% Zn. 11

12 CO-20 Next Steps EM has no obvious correlation with the gold other than possibly in the Smoke Budget 12
