Highland Mining and Minerals Co. is considering the purchase of two gold mines. Only one investment will be made. The Australian gold mine will cost $1,677,000 and will produce $385,000 per year in years 5 through 15 and $529,000 per year in years 16 through 25. The U. S. gold mine will cost $2,036,000 and will produce $299,000 per year for the next 25 years. The cost of capital is 7 percent. Use Appendix D for an approximate answer but calculate your final answers using the formula and financial calculator methods. (Note: In looking up present value factors for this problem, you need to work with the concept of a deferred annuity for the Australian mine. The returns in years 5 through 15 actually represent 11 years; the returns in years 16 through 25 represent 10 years.) a-1. Calculate the net present value for each project
