Copper was first discovered in 1870 in a town called Cobar. BPH resources currently own an unused copper mine in Cobar that was shut down four years ago due to the depressed price of copper. However, due to the recent resources boom, BPH are considering re-opening the mine. Company management forecast that it would cost $100,000 to re-open the mine and they would extract 100,000 pounds of copper per year for three years if the mine was re-opened. After that time the deposit will be exhausted. The current copper price is $4 per pound and it costs $3.60 per pound to extract. Each year the price is equally likely to rise or fall by $0.50 from its level at the start of the year. Assuming a discount rate of 10% should BPH open the mine now or should they wait one year to see if the price of copper rises?
