Title 26 › Subtitle Subtitle A— - Income Taxes › Chapter CHAPTER 1— - NORMAL TAXES AND SURTAXES › Subchapter Subchapter I— - Natural Resources › Part PART I— - DEDUCTIONS › § 616
You can deduct costs you pay to develop a mine or other natural deposit (not oil or gas wells) after it is shown that saleable ores or minerals exist. You cannot use this rule for buying or improving property that is depreciated, although allowed depreciation is treated as a development cost for this rule. You may choose, under the government’s rules, to treat these costs as deferred and write them off gradually as the units of ore or mineral are sold. If the mine is still in its development stage, that choice only applies to the part of costs that is more than the year’s net receipts from sales. The choice must cover the whole amount for the mine and is binding for that tax year. Deferred costs are added to the mine’s adjusted basis but are ignored when figuring depletion. For a mine or deposit located outside the United States (not oil, gas, or geothermal wells), the normal and deferred rules above do not apply. Instead you can either add the costs to basis for purposes of computing depletion (without regard to section 613), or, if you do not do that, you must deduct the costs evenly over a 10-taxable-year period starting in the year you paid them. An election for 10-year amortization is available under section 59(e).
