11. 5 % Metamorphic3% Post-Jurassic (Leech River)2% Pre-Jurassic (West Coast Complex)
12. 10% Quaternary Sediment Cover
13. MINFILE Totals
14. MINFILE TotalsDimension Stone deposit data incomplete to absentCoal deposit data limited but tonnage is significantMetallic deposit data extensive and interestingCopper, Gold, Zinc and Iron most significant metals>C$55 Billion in 185 metal deposits at todays prices
15. Producers & Past Producers
16. Producers & Past ProducersDimension stone deposit data largely absentCoal deposit data historically very significantMetallic mineral deposit data dominatesCopper, Gold, Zinc and Iron most significant metals>C$25 Billion in 123 metal deposits at todays prices
17. Developed Prospects
18. Developed ProspectsLimestone deposits on Texada Island & Northern Vancouver Island dominate industrial minerals dataCoal data dominated by Comox area depositsCopper and Gold most significant metals >C$30 Billion in 64 metal deposits at todays prices
19. MINFILE Metallic Mineral Totals
20. MINFILE Metallic Mineral TotalsCopper primarily in Porphyry DepositsGold mainly in Porphyry Deposits, but Exhalative (VMS) Deposits contribute significantly as wellZinc entirely in Exhalative (VMS) DepositsIron almost entirely in Skarn Deposits
21. Metallic Producers & Past Producers
22. Metallic Producers & Past ProducersCopper mainly from Porphyry and VMS depositsGold mainly as by-product from VMS Cu-Pb-Zn-Ag-Au and Porphyry Cu-Mo-Au deposits, with some from Au Quartz VeinsZinc entirely from VMS depositsIron mainly from Fe-Cu Skarn deposits
23. Metallic Developed Prospects
24. Metallic Developed ProspectsCopper mainly in Porphyry deposits, with some in VMS depositsGold mainly in Porphyry Cu-Mo-Au deposits, with significant amounts in both VMS Cu-Pb-Zn-Ag-Au and Au Quartz Vein depositsZinc almost exclusively in VMS depositsIron almost exclusively in Fe-Cu Skarn deposits
25. Mineral Deposit SettingsConvergent Plate Boundary – Island Arc: Porphyry, Epithermal, Skarn, VeinsDivergent Plate Boundary – Spreading Centre: VMS (Exhalative)
26. Mineral Deposit Models
27. Porphyry/Skarn/Vein Deposit SettingsClustered Together!
28. Porphyry/Skarn/Vein Deposit Models/ProfilesCo-genetic and Co-spatial Relationships!Current Erosional Level determines Deposit Depth!
29. Skarn Deposit Settings
30. Volcanogenic Massive Sulphide (VMS) Deposit Settings
31. Volcanogenic Massive Sulphide (VMS) Deposit Models/Profiles
32. Key PointsWidely varied commodities and deposit typesCopper, Gold, Zinc, Iron are metals of greatest valueMetallic production >C$25 Billion at todays pricesMetallic developed prospects >C$30 Billion!Metallic deposit types to target:Porphyry Cu-Mo-Au (Jurassic, Eocene, Miocene)VMS Cu-Pb-Zn-Ag-Au (Devonian)Fe-Cu Skarn (Jurassic, Eocene, Miocene)
