1 MINING ORE VALUATION BY REAL OPTION UNDER UNCERTAINTY AND RISK Ph.D Manuel Viera Ceo& Managing Partner Metaproject S.A

2 Strategic Mining Investments Are exposed to a high level of uncertainty Big amounts of money on the table Complex capital structures. Political risk and all kinds of financial risk. Flexibility is really important

7 How big are the known reserves? What is the level of confidence? What is the level of risk associated with? Which is the expected return? When ore deposit is economically attractive, arise a series of questions such as:

8 Value Quality and Risk How increase NPV? EVA QualityRisk Added Asegura Income Costs ++++ ---- NPV Expected value La Gestión de Calidad y Riesgo se justifica si el beneficio es mayor a su costo

10 Evolution of Valuation Methods DCF analysis was introduced in the 1950’s and first applied to petrochemical projects. Prior to that the Payback method prevailed. Sensitivity and Scenario analysis were developed at the US Air Force and the first corporate use occurred at Shell later in that decade. The advent of computers brought simulation methods in the 1960’s and decision trees. Option theory was developed in 1973, and applications to real assets occurred a few years later.

12 Alternative methods to price real options Analitic (closed formula) models like Black- Scholes:Big biases because their assumptions are unrealistic Traditional decision trees. Binomial models (lattices).-Good alternative but we need to know the binomial process parameters for the underlying project. Montecarlo simulation.- Maybe a black box

13 Mining Projects Integral Evaluation Methodology through Real Options Step 1: Review and Define the Mining Business Strategy Step 2: Determine Geological Uncertainty Level. Step 3: Perfect Information Level and Information Quality Step 4: Mining Resources Cubication and Valuation. Step 5: Determination of Engineering Level (Information Quality). Step 6: Calculation of Optimal Production Rate. Step 7: Metals and main Supplies Price Projection. Step 8: Determination of the Project’s Risks and Dangers. Step 9: The Normal Portfolio of Projects, to determine which candidates will be evaluated by Real Options Step 10: Scenarios and variables taken into account to Evaluate Projects. Step 11: Definition of the Decision Trees with Flexibilities. Step12: Selection of the Strategic Flexibilities and Options

32 Main conclusions

33 MAIN CONCLUSIONS The Latin Hypercube or Montecarlo Simulation with reversion to the mean has resulted to be a good copper and molybdenum price forecast model, allowing a better valuation of the mining property project. The NPV criterion is rigid and doesn’t allow visualizing the strategic value of mining flexibilities. The Option to expand has resulted as the best decision. The DELPHI/HAZOP experts panel is a good method to determine the uncertainty level of the ore deposit, in order to apply the Options theory.
