                               (CONTINUED)
 
PART 1_INCOME TAXES--Table of Contents
 
Sec. 1.615-1  Pre-1970 exploration expenditures.

    (a) General rule. Section 615 prescribes rules for the treatment of 
expenditures (paid or incurred before January 1, 1970) for ascertaining 
the existence, location, extent, or quality of any deposit of ore or 
other mineral (other than oil or gas) paid or incurred by the taxpayer 
before the beginning of the development stage of the mine or other 
natural deposit. Such expenditures hereinafter in the regulations under 
section 615 will be referred to as exploration expenditures. The 
development stage of the mine or other natural deposit will be deemed to 
begin at the time when, in consideration of all the facts and 
circumstances (including the actions of the taxpayer), deposits of ore 
or other mineral are shown to exist in sufficient quantity and quality 
to reasonably justify commercial exploitation by the taxpayer. A 
taxpayer who elects under section (e) may treat exploration expenditures 
under either section 615(a) or section 615(b). See Sec. 1.615-6 for the 
method of making the election to treat exploration expenditures under 
section 615. Under section 615(a), a taxpayer may, at his option, deduct 
exploration expenditures paid or incurred in an amount not to exceed 
$100,000 for any taxable year. Under section 615(b) and Sec. 1.615-2, 
he may elect to defer any part of such amount and deduct such part on a 
ratable basis as the units of produced minerals benefited by such 
expenditures are sold. If the taxpayer does not treat exploration 
expenditures under either section 615 (a) or (b) in any year for which 
his election under section 615(e) is effective, the expenditures for 
such year will be charged to depletable capital account. The option to 
deduct under section 615(a) and the election to defer under section 
615(b), however, are subject to the limitation provided in section 
615(c) and Sec. 1.615-4. In the case of certain corporations which are 
members of an affiliated group which has elected the 100 percent 
dividends received deduction under section 243(b), see section 243(b) 
(3) and Sec. 1.243-5 for limitations on the option to deduct under 
section 615(a) and the election to defer under section 615(b).
    (b) Expenditures to which section 615 is not applicable. (1) Section 
615 is not applicable to expenditures which would be allowed as a 
deduction for the taxable year without regard to such section.

    (2) Section 615 is not applicable to expenditures which are 
reflected in improvements subject to allowances for depreciation under 
sections 167 and 611. However, allowances for depreciation of such 
improvements which are used in the exploration of ores or minerals are 
considered exploration expenditures under section 615. If such 
improvements are used only in part for exploration during a taxable 
year, an allocable portion of the allowance for depreciation shall be 
treated as an exploration expenditure.
    (3) Section 615 is applicable to exploration expenditures paid or 
incurred by a taxpayer in connection with the acquisition of a 
fractional share of the working or operating interest to the extent of 
the fractional interest so acquired by the taxpayer. The expenditures 
attributable to the remaining fractional share shall be considered as 
the cost of his acquired interest and shall be recovered through 
depletion allowances. For example, taxpayer A owns mineral leases on 
unexplored mineral lands and agrees to convey an undivided three-fourths 
(\3/4\) interest in such leases to taxpayer B provided B will pay all of 
the exploration expenditures for ascertaining the existence, location, 
extent, or quality of any deposit of ore or other mineral which will be 
incurred before the beginning of the development stage. B shall treat 
three-fourths of such amount under section 615, and shall treat one-
fourth of such amount as part of the cost of his interest, recoverable 
through depletion.
    (4) The provisions of section 615 do not apply to costs of 
exploration which are reflected in the amount which the taxpayer paid or 
incurred to acquire the property. Such provisions apply only to costs 
paid or incurred by the taxpayer for exploration undertaken directly or 
through a contract by the taxpayer. See, however, sections 381(a) and 
381(c) (10) for special rules with respect to deferred exploration 
expenditures in certain corporate acquisitions.
