Smithson Mining operates a silver mine in Nevada. Acquisition, exploration, and development costs totaled $6.7million. After the silver Is extracted in approximately five years, Smithson is obligated to restore the land to its original condition, including constructing a wildlife preserve. The company's controller has provided the following three cash flow possibilities for the restoration costs: (1) $610,000,10% probability; (2) $660,000,50% probability; and (3) $760,000,40% probability. The company's credit-adjusted, fisk-free rate of interest is 7\%. (FV of \$1. PV of \$1. EVA of \$1, PVA of \$1. EVAD of \$1 and PVAD of \$1) (Use appropriate factor(5) from the tables provided.) What is the initial cost of the silver mine? (Do not round intermediate calculations. Enter your answers in whole dollars.)
