MEMORANDUM FINDINGS OF FACT AND OPINION

FAY, Judge: Respondent determined deficiencies in petitioner's Federal income tax as follows:

FYEDeficiency
March 31, 1970$44,200
March 31, 197141,509
March 31, 19727,175

The deficiencies pertain to petitioner's method of computing percentage depletion under*305 section 613. 1 Specifically, we are to decide whether petitioner has made a proper application of the proportionate profits method of determining gross income from mining.

FINDINGS OF FACT

Petitioner is a Utah corporation which maintained its principal place of business at Salt Lake City, Utah, when the petition herein was filed. For each of the years in issue it filed a corporate income tax return with the Western Service Center, Ogden, Utah.

Petitioner is an integrated miner-manufacturer of Portland cement. It has for many years engaged in the quarrying of an argillaceous limestone rock, 2 known in the trade as cement rock, and in the processing of that rock into finished Portland cement.

The manufacture of Portland cement begins with the mining of cement rock. Petitioner obtains cement rock from its own quarry located 12 miles from its Salt Lake City processing plant. The cement rock is first blasted free of the mountainous quarry face, then*306 pushed by bulldozer to the quarry floor. Secondary blasting is employed, if necessary, to further reduce the size of large boulders. The loose rock is then transported to "reduction" machinery where it passes through a jaw crusher and an impacter which further reduce the material to a size of less than one inch. The crushed material is stored temporarily at the quarry in bins awaiting loading into trucks for transportation to the processing plant.

Arriving at the processing plant, the material is unloaded and placed in open stockpiles. The material is then fed into rod-ball mills which grind the rock to a fineness so that 75 percent volume passes through a 200 mesh sieve. During this grinding process, water is added to the powder and a "slurry," a very fine mud, is formed. The slurry is stored in tanks where it is continually agitated to maintain a uniform mixture. The mining phase of the operation concludes at this point.

During the manufacturing phase, the liquid slurry is fed into rotary kilns and burned. The heat of the kiln expells moisture from the material and converts carbonates to oxides. As the material is heated to a point of incipient fusion, complex silicates*307 and aluminates are formed by chemical reactions occurring inside the kiln. The result of the burning process is a hard, glass-like "clinker." The clinker is cooled and later ground with purchased gypsum to produce finished cement.

The rock in taxpayer's quarry varies in chemical composition. Certain areas within the quarry do not contain all the ingredients necessary to produce finished Portland cement. When rock is quarried from these areas it becomes necessary to add to the cement rock supplementary chemical materials. The various chemical supplements are added to the cement rock during the grinding phase in the rod-ball mill. High lime rock is added to correct any calcium carbonate deficiency in the quarried rock; iron slag is added to correct any iron deficiency; silica is added to compensate for lacking silica oxides.

If the required amounts of calcium carbonates, iron and silica oxides are not present in the slurry as it is introduced into the kiln, chemical actions required to produce a clinker from which Portland cement can be made will not occur. It is only when the proper proportions of materials are introduced into the rod-ball mill that the necessary chemical reactions*308 will take place during the burning in the kilns. Frequent chemical analyses are made by petitioner's chemists to ensure that the slurry is of a proper composition for making Portland cement.

After final grinding, finished cement is placed in storage silos to await sales to customers. Petitioner's finished cement is sold in two ways. Most of petitioner's output is sold in bulk in tank cars, loading directly from the storage silos. A small portion of the output is run from the storage silo into a bin above a bagging machine where it is sealed in paper bags and thereafter sold in that form. 3

OPINION

In computing the amount of its gross income from mining, a component necessary to arriving at its percentage depletion allowance for the years in issue, petitioner utilized the proportionate profits method of computation.*309 See sec. 613.
