Current Attempt in Progress

Sheffield Mining Company has purchased a tract of mineral land for $$1,206,000.$ It is estimated that this tract will yield $160,800$ tons

of ore with sufficient mineral content to make mining and processing profitable. It is further estimated that $8,040$ tons of ore will be

mined the first and last year and $16,080$ tons every year in between. $($Assume $11$ years of mining operations.$)$ The land will have a

salvage value of $$40,200.$

The company builds necessary structures and sheds on the site at a cost of $$48,240.$ It is estimated that these structures can

serve $15$ years but, because they must be dismantled if they are to be moved, they have no salvage value. The company does not intend

to use the buildings elsewhere. Mining machinery installed at the mine was purchased secondhand at a cost of $$80,400.$ This

machinery cost the former owner $$201,500$ and was $50\%$ depreciated when purchased. Sheffield Mining estimates that about half of

this machinery will still be useful when the present mineral resources have been exhausted, but that dismantling and removal costs

will just about offset its value at that time. The company does not intend to use the machinery elsewhere. The remaining machinery

will last until about one$-$half the present estimated mineral ore has been removed and will then be worthless. Cost is to be allocated

equally between these two classes of machinery.

$($a$)$

Your answer is partially correct.

As chief accountant for the company, you are to prepare a schedule showing estimated depletion and depreciation costs for each

year of the expected life of the mine. $($Round per unit answers to $2$ decimal places, e$.$g$.0\mathrm{.}45$ for computational purposes and final

answers to $O$ decimal places, eg$.45,892.)$
