Mineral reserves Mr = 500 000 tons of quartz sands

Acquisition cost K = $3 million

Overburden removal, road upgrade, marketing Kg = $550 000

Equipment cost Ke = $650 000

Annual tonnage T = 25000

Cost the mine, process, package and transport per tonne C = $25

Tax rate = 35%

Annual depreciation straight-line method M =

Salvage value S = $240 000

Rate of return r = 20%

What equation for the NPV of the project looks like using the numbers above and assuming continuous cash flow and continuous discounting?

I should note that the task is similar to my homework!
