Show ; Mine Firm Opens j South Utah Property Expanding its operation to develop additional Utah resources . and produced more metal for the t war effort, the Ohio Copper com-I com-I pany of Utah, last year opened up and placed In production the Big ! Indian mine, situated near La Sal ! in San Juan county. I After checking the tonnage and grade of ore available and satisfactorily satis-factorily completing metallurgical : tests, construction of a treatment ! plant was undertaken in the spring , of 1943. The milling plant has a daily capacity of 250 tons of cop-j cop-j per ore. Construction of the mill , and related buildings was com-I com-I pleted late In 1943 and the break-l break-l ing in period was started. Dif-! Dif-! Acuities in starting the new plant were encountered and resulted in an operating loss of $18,811.52 for the year. The Big Indian mine operation is in addition to the company's regular operation In the Bingham district where copper is produced by leaching leach-ing in place methods. By this unique method, copper is extracted from the water that percolates through the low-grade porphyry ore in the mine. The additional mining, such as has been undertaken by Ohio Copper Cop-per results in more metal, more payrolls and added business for smelters, railroads and other Industries In-dustries throughout the state. In encouraging this type of development develop-ment of Utah's resources, the long term position of the state is improved. |
