A coal mining company expects to receive $$64,605,966$ per year for the sale of its clean coal product. Opening the mine and processing facility will require $$151,663,602$ in capital expense. Operating and maintenance costs are expected to require expenditures totaling $$6,984,560$ per year. The useful life of the mine is expected to be $10$ years, and the corporate discount rate is $4\%.$ The mine and processing equipment have no salvage value. The composite tax rate is $40\%.$ In addition to the economic information, the total deposit includes $6\mathrm{.}4$ million tons of coal which will be mined at $800,000$ tons per year. The mineral rights for this deposit originally cost $$8\mathrm{.}30$ million. The depletion rate is $10\%.$ What is the NPV of this project considering tax consequences with depreciation and depletion? Assume that the full capital cost can be depreciated over $10$ years using the straight line method.

Note: the year $0$ costs should include both the $$151,663,602$ capital expense AND the $$8\mathrm{.}30$ million mineral rights costs.
