Net Present Value Calculation
source: http://en.wikipedia.org/wiki/Net_present_value
- the time of the cash flowi- the discount rate(therate of returnthat could be earned on an investment in the financial markets with similar risk.); the opportunity cost of capitalRt - the net cash flow (the amount of cash, inflow minus outflow) at time t. For educational purposes, R0 is commonly placed to the left of the sum to emphasize its role as (minus) the investment."
T = 10 years
I = Discount Rate
R = Net Cash Flow
The Discount Rate
The discount rate should be equal to the recovery rate, as this is the risk in processing. Dilution is also a major risk, as is currency fluctuations, but for the most part the recovery rate is the risk set by the discount rate. The company chose the recovery rate of 93%, which is highly likely meant to conform with a 7% discount rate, rather than the real recovery rate of the mill. The mill has concentrators, so if they achieved this rate of recovery, they must either have the concentrators completely switched off, or they pulled this number out of a hat.
Moreover, using a 7% discount rate will grossly underestimate the Net Present Value of the company using the above formula. The discount rate should be -10%, as the gold price has advanced 17% yoy since the last 10 years. So the sum of the discount rate is only .9.
