The GreatOreCo mining company wishes to determine whether it should proceed to develop a copper mine for a lease that it owns. There would be substantial development costs involved, and the mine would be expected to have a life span of nine years. The company would also be faced with environmental rehabilitation costs when the mine is closed down, and this is reflected by a smaller contribution in the mines final year of operation. Projected costs and yields have been determined and the resulting cash flows are summarised in the table below:
1. If the company applies a discount rate of j1 = 15%, determine the Net Present Value (present value of the entire cash flow).
To compare the investment in the copper mine with other possible investments that GreatOreCo could make, management need to know the Internal Rate of Return (IRR) for the proposed copper mine. The IRR is the discount rate j1 for which the NPV of the project is zero. That is, the j1 rate for which PV(set up costs) = PV(operational profit contributions)
2. Using an estimate of j1=18%, determine the value of the left hand side (costs) and the right hand side (profit contributions) of the equation of equivalence. Enter these two values to the nearest dollar as an answer.
3 Derive and present the equation of equivalence that is appropriate for this scenario? Do NOT seek to simplify the expression. NB [Hint: Have expressions involving the 80 and the 20 on the left hand side, and expressions involving the 25s and the 10 on the right hand side. This is a Price is Right type of problem].
4. Present your next three estimates of j1 and the corresponding value of the right hand side of the equation of equivalence? Each of these three steps need to Explain Why you increased or decreased the value of j1?
