    • 4. BEHRE DOLBEAR founded 1911 MINERALS INDUSTRY ADVISORS Metals Demand Has Grown, Sentiment Now Is Cautious • Urbanization, industrialization continues in China, SE Asia, India, parts of LatAm, MENA driving industrial metals and energy demand • Security & stability of supply are a concern in China, Korea, Japan, Middle East, etc. and select co.s e.g., fuel (coal, uranium), fertilizer minerals, technology/critical metals, etc. • Economic growth in China, EU, etc. is slower • Metals prices and valuations are down • Risk-off attitude is plaguing sector
    • 5. BEHRE DOLBEAR founded 1911 MINERALS INDUSTRY ADVISORS China‟s Population Continues to Urbanize
    • 6. BEHRE DOLBEAR founded 1911 MINERALS INDUSTRY ADVISORS Largest Mass Migration in History Sets Theme for World‟s Rising Middle Class • In the next 20 years, ~325 million people to move to urban areas in China • China‟s middle class may to double to 600+ million by 2020 • A similar shift is occurring elsewhere around the world
    • 7. BEHRE DOLBEAR founded 1911 MINERALS INDUSTRY ADVISORS China Consumes About Half the World‟s Metals, Energy, etc. Source: UBS
    • 8. BEHRE DOLBEAR founded 1911 MINERALS INDUSTRY ADVISORS China‟s Share of Global Metals Consumption May Level Off Source: The Economist and UBS
    • 9. BEHRE DOLBEAR founded 1911 MINERALS INDUSTRY ADVISORS Cautious Now; Long Term Demand Positive • Mining companies have reduced spending • Investors and lenders are very cautious • Cash is king, may be primed for M&A • Many „Juniors‟ are short of capital • Tough markets may go into 2014 • Longer term - supply may struggle to meet demand • Sporadic price spikes in metals markets can occur • Constraining new supply are: Declining ore grades; Higher costs; Fewer large deposits; Larger „takes‟ by Governments; Changing political winds; etc.
    • 10. BEHRE DOLBEAR founded 1911 MINERALS INDUSTRY ADVISORS Gold <$1,300/oz Is Well Below Recent Highs, Narrowing Margins - How Low Can It Go? Source: BMO Research

BEHRE DOLBEAR founded 1911 MINERALS INDUSTRY ADVISORS Since Sept 2011 Metals Equities Fell Disappointed Investors Flock to S&P Source: Cowen Securities - 50% 100% 150% Sep-11 Nov-11 Jan-12 Mar-12 May-12 Jul-12 Sep-12 Nov-12 Jan-13 Mar-13 GDXJ Coal Index Copper Index S&P 500 Source: Capital IQ. Data as of April 26, 2013. Note: Coal Index represents Dow Jones U.S. Coal Index. Copper Index based on Cowen Securities Investment Banking coverage database.
    • 12. BEHRE DOLBEAR founded 1911 MINERALS INDUSTRY ADVISORS Cautious, Deliberate, Long Term View Is Core to Cyclical Mining Business • You can lose a fortune being optimistic about the near term future – some have already • As a legendary analyst said “Be careful about looking to mountain tops as paths through valley floors can be treacherous” • Behre Dolbear focuses on geo-technical, operating, business & financial issues that impact exploration, development, operations • We do not forecast metals prices
    • 13. BEHRE DOLBEAR founded 1911 MINERALS INDUSTRY ADVISORS When To Call Independent Experts • It is best to get Qualified expert advice early on whether you are an owner, investor, etc. • All too often experts are called when: The company is out of money Lenders are out of patience Despair has set in • Caveat Emptor – Buyer Beware • Profitable projects are few
    • 14. BEHRE DOLBEAR founded 1911 MINERALS INDUSTRY ADVISORS The Business Goal Is To Realize Value: How? When?
    • 15. BEHRE DOLBEAR founded 1911 MINERALS INDUSTRY ADVISORS Finding A Gold Mine Is Costly and Risky It All Starts With Exploration
    • 16. BEHRE DOLBEAR founded 1911 MINERALS INDUSTRY ADVISORS Exploration Is Core to Mining What To Look For Mining companies and management feel obliged to find and develop new competitive, low cost resources, i.e., their Life Blood – to replace existing reserves – that are diminishing assets – and to Stay Competitive MANAGEMENT & INVESTORS BEWARE! Once a Fido = Dog, Always a Phydeaux = A Higher Class Dog is Still A Dog!
    • 17. BEHRE DOLBEAR founded 1911 MINERALS INDUSTRY ADVISORS Why Trained, Qualified Eyes Are Needed • Best properties are low cost, in stable jurisdictions & likely expansions/extensions of existing mines • Top rate management always essential • Understanding terms and markets critical • „Resources‟ are concentrations or occurrences of minerals in such form and quantity and of such grade or quality that they have reasonable prospects for economic extraction • Terms, definitions, methods used to evaluate a property can vary by user & jurisdiction BEWARE
    • 18. BEHRE DOLBEAR founded 1911 MINERALS INDUSTRY ADVISORS In the Best Case: Accepted Resource-Reserve Classification Systems are Used Australia JORC Code Canada CIM 2000 / NI 43-101 Europe PERC South Africa SAMREC Code United States SME / SEC Industry Guide 7 Russia A, B, C, D, E China Traditional and New (1999)
    • 19. BEHRE DOLBEAR founded 1911 MINERALS INDUSTRY ADVISORS In the Worst Case: Beware of Fraud • If it sounds too good, it likely is • Look for misleading statements • Know who you are dealing with, etc. • Evaluate circumstances relative to history • There is no good substitute for an Independent, Qualified Expert review – too many variables and too long a period of time are involved • Being diligent using Rules of Thumb, Common Sense, etc. are not good enough
    • 20. BEHRE DOLBEAR founded 1911 MINERALS INDUSTRY ADVISORS Economic Worthiness of a Property Is Impacted By Many, Many Variables Study these and many other items with discerning, trained eye: • Property Information and Stable Regulatory Environment • Geology and Resources • Mining • Mineral Processing and Metallurgy • Infrastructure • Products, Markets and Sales • Environmental and Permitting • Financial Issues • Development Costs and Schedule • Political and Social Considerations • Market • Project Economics – Opex and Capex
    • 21. BEHRE DOLBEAR founded 1911 MINERALS INDUSTRY ADVISORS From Discovery To Start Up = ~17 Years
    • 22. BEHRE DOLBEAR founded 1911 MINERALS INDUSTRY ADVISORS Three Levels of Engineering Studies Used to Define Economic Worthiness Conceptual Study/Scoping Study Pre-feasibility Study Feasibility Study
    • 23. BEHRE DOLBEAR founded 1911 MINERALS INDUSTRY ADVISORS Engineering Studies – Scoping Study • aka Conceptual Study, Preliminary Economic Analysis • First engineering study to compile all elements of a project into one evaluation and apply economic tests • Its accuracy is based on first principles, knowledge, and experience and is generally +50% / -25% • This is the least expensive engineering study and is usually completed in 90 days or less
    • 24. BEHRE DOLBEAR founded 1911 MINERALS INDUSTRY ADVISORS Engineering Studies – Pre Feasibility Study • aka PFS or Pre-Feasibility Study • Accurate to +25% / -15% • May take 6 to 18 months to complete • Engineering evaluation applied to key elements, such as • The caliber of the resource estimate • The mine design • The process design • Mineralogical analysis • Metallurgical testing • Soil and rock engineering tests • Smelting/refining and marketing • Environmental work – the EIA is completed during the PFS • Cash flow analysis, sensitivity analyses, and economic tests
    • 25. BEHRE DOLBEAR founded 1911 MINERALS INDUSTRY ADVISORS Engineering Studies – Feasibility Study • Feasibility Study or Definitive Study • The document upon which mine is approved by the Board of the mining company developing the mine • If financing is required, this is the document evaluated by financial institutions in their decision-making process • The Feasibility Study is also the document to which the completed and commissioned mine plan is compared to determine its commercial status
    • 26. BEHRE DOLBEAR founded 1911 MINERALS INDUSTRY ADVISORS Definition – Feasibility Study “A comprehensive study of a mineral deposit in which all geological, engineering, legal, operating, economic, social, environmental and other relevant factors are considered in sufficient detail that it could reasonably serve as the basis for a final decision by a financial institution to finance the development of the deposit for mineral production.” - Canadian National Instrument 43-101

    • 43. BEHRE DOLBEAR founded 1911 MINERALS INDUSTRY ADVISORS © 2011 Behre Dolbear Group Inc. All Rights Reserved Four Issues Impacting Project Success Today • Social Issues/Social License to Operate • Costs Control • Higher Government Take/Resource Nationalism • Access to Capital
    • 44. BEHRE DOLBEAR founded 1911 MINERALS INDUSTRY ADVISORS 1. Social Issues/Social License to Operate • Social, Economic, Regulatory issues are a leading cause of project delay & cost increases • Striving to be compliant with regulations and NGO agitation, etc. are contributing to higher project costs and delays • Gaining confidence for Social License to operate is essential
    • 45. BEHRE DOLBEAR founded 1911 MINERALS INDUSTRY ADVISORS 2. Costs Control Needed • Capex rising through cycle • Capex lags rise in metal prices • Number of blow ups increasing • Long investment horizons • Project development • Reserve expansion Per Unit of Annual Production (US$) Gold $1,250 to $2,500 per oz of annual production Copper $3.50 to $4.50 per lb of annual production Capital Costs
    • 46. BEHRE DOLBEAR founded 1911 MINERALS INDUSTRY ADVISORS Building Mines – Capital Costs • Capital costs are primarily dependent on  Location, political situation, skilled labor availability  Depth of ore zone and mining horizons  Shaft or adit/ramp access  Plant size − Shaft size and hoisting capacity − Equipment fleet size and material handling capacity − Processing plant capacity to match mining rate  Mining method − Level of mechanization and automation − Productivity per man shift
    • 47. BEHRE DOLBEAR founded 1911 MINERALS INDUSTRY ADVISORS Different Geology; Different Economics • Of the world‟s gold production the bulk is from sulphide ore rather than oxide ore • The project, operating economics are different • Representative indicative measures: Sulphide Ore: Capex low grade $300 to $700+ million; minimum 2 to 5m oz Oxide Ore: Capex is scalable with Opex =1/5 of Sulphide; minimum scale can be small
    • 48. BEHRE DOLBEAR founded 1911 MINERALS INDUSTRY ADVISORS What Can Go Wrong: Issues To Look For Mine Operating Cost Estimation • Fuel and electricity costs under estimated • VAT/sales tax, not included and import duties neglected • Improper cycle times & haulage distances used • Mining sequence and methods • Ground control under estimated • Inadequate pre-stripping • Poor haul road design • Pit slopes • Dilution • Poor waste dump design • Etc.
    • 49. BEHRE DOLBEAR founded 1911 MINERALS INDUSTRY ADVISORS Recent Examples of Capital Costs Rising Above Plan (US$ Billions) Project Original Current Pueblo Viejo 2.5 3.5 Galore Creek 2 5+ Cerro Casale 2 6 Pascua Lama 3 8+
    • 50. BEHRE DOLBEAR founded 1911 MINERALS INDUSTRY ADVISORS 3. Increased Government Take • Changing measures and Government „takes‟ at local, state, and federal levels are today‟s reality • A global concern – Raises Project Uncertainty • In normal mining cycles, a project will fail if Government take exceeds 50% • Mining companies take all the risk
    • 51. BEHRE DOLBEAR founded 1911 MINERALS INDUSTRY ADVISORS 4. Access to Capital • Currently, equity and debt difficult to obtain • New sources of funding need to be found • Private Equity, State Owned Enterprises, etc. may play a larger role
    • 52. BEHRE DOLBEAR founded 1911 MINERALS INDUSTRY ADVISORS Recent Capital Markets Trends • Metals markets in 2012 & 1H13 are turbulent - at best • A long term perspective is needed in mining business • Banks, investors and operators are now risk adverse • Management, stakeholders, employees, partners & customers need to be realistic about options • This uncertainty may continue well into 2014 • Alternative and strategic investors, private equity, SWFs and SOEs may opportunistically step in
    • 53. BEHRE DOLBEAR founded 1911 MINERALS INDUSTRY ADVISORS More Consolidation in Mining is Likely • Valuations are less expensive than greenfield investment • Consolidation to form Super and Larger Majors is likely • SOEs, SWFs e.g. Japan, Korea, India likely to continue to acquire strategic metals and energy fuel resources, etc. • Strategic M&A may buoy mining assets and share prices
    • 54. BEHRE DOLBEAR founded 1911 MINERALS INDUSTRY ADVISORS Of the Top Ten Commodities by Global Projects in 2011: Gold Was #1 • Investors, lenders, & speculators were attracted to precious metals • What will 2013/4 look like? Source: Intierra
