Given below in table 1 are hypothetical data on costs and benefits of a proposed small mine to be constructed in remote Telefomin district in Sundaun Province. Table 1: Summary of total costs and benefits ( K millions) Undertake the following: (a) Calculate the NPV, IRR and BCR (use 8% discount rate). Interpret the results. (b) Conduct a sensitivity analysis by reducing the life of the project to 6 years and recalculate the NPV, IRR and BCR (use 10\% discount rate). Interpret the results and contrast to (a) above. (c) The above costs and benefits are based on market prices. Explain how you would incorporate externalities or costs and benefits associated with environmental consequences by employing non-market valuation techniques. (d) Calculate the cost effectiveness (CE) ratio if the total impact of the project is valued at K10 billion. Interpret
