5. (Chp 12) Co. Q is considering opening a platinum mine in Russia. It is estimated that the mine will cost \$100 million to develop this year. Experts suggest that the mine will produce .5 million ounces per year for the next three years at a cost of \$200 an ounce. Co. Q expects that the price of platinum will rise 10% per year from its current level of \$1,400 per ounce. The rate of discount is 15%. Find the net present value of the mine. [hint: the first .5 million ounces of platinum is extracted at the end of this year and the value should be discounted at 15%]
