5 What s s of interest here? Initial search for massive sulfide and/or IF type mineralization Reassessed for SHV potential Explored now with SHV model as target New concept Potential for discovery of a large Au deposit

6 Work Completed and Results Initial Sampling Stream silt Heavy mineral BLEG Soil Numerous gold anomalies occur along the Misinchinka Range consistent with SHV type mineralization

18 So - What is a Sediment-Hosted Vein Deposit? Also known as Turbidite-hosted Shale-hosted Orogenic Deposits (subset) Mesothermal Vein (subset) Class of deposits with unifying characteristics Shale SHV Turb. Orogenic/Mesothermal Deposits

19 Unifying Characteristics Host rocks Tectonic setting Structural elements Mineralization characteristics Alteration HT fluid Age? Regional shale-siltstone sequence Passive margin Near shear zone with cross structures Quartz carbonate ± sulfide veins + Au Carbonate ± sericite Early Paleozoic host rocks; mid late Paleozoic mineralization

20 These deposits are important because: They can be giants: >150 tonnes; ; 5M oz Au 6 6 deposits >10 M oz Contribution as a class of deposits: 9,000-10,000 tonnes (~300 M oz) Au contained in largest 13 deposits

21 Tonnes Au Porphyry Epithermal (HS +LS) SHV Arch. Lode Other Sed-hosted Carlin Intrusive-hosted Fe Fm Sh. Zone VMS Contained Gold by Deposit Type (for Deposits >150 tonnes Au) Paleo Placer 50K

35 Tectonic Setting Passive continental margin Overlying or in proximity to the margin of crystalline basement (craton) Thin-skinned(?) fold-thrust deformation X X

36 Structural Elements Anticlines are key!

37 Structural Elements anticlines

38 Structural Elements Muruntau Besopan, Uzbekistan Late-stage crenulation Ovens, Nova Scotia

39 Structural Elements Late-stage Au qtz- carb-sulf veins fill crenulation features

40 Mineralization 1 Ribbon veins Simple mineralogy Native Au Carbonaceous content Au

41 Mineralization Characteristics 2 Associated with prolific placer fields Lena District, Siberia >22M oz Au

42 Mineralization Characteristics 3 Pre-, syn-, and posttectonic quartz- carbonate+-sulfide veins

43 Mineralization Characteristics 4 Strong As, Sb, W, Bi, +/-U metal association Low Cu, Pb, Zn association

44 Alteration Pervasive regional carbonate alteration Large zonation patterns are not apparent Altered rocks weather to bleached pastel hues Fe-carbonate weathers to yellow-brown

45 Wrap-up Wealth Minerals has: Identified regional area suitable for SHV type mineralization Conducted regional sampling Identified numerous anomalous areas consistent with the occurrence of SHV mineralization Is excited about their 2006 program!
