Show THE CITIZEN ONE OF WORLDS LARGEST PRODUCING COPPER MINES. better known and of more interest in its operation than that of the Utah Copper, located at Bingham. The property and holdings are of immense extent and comprises No property is the original groups secured by Col. D. C Jackling and that of the Boston Con., which was opened and first operated by Samuel Newhouse, and later secured by the Utah Copper. Nature is not in the habit of placing its metals where they are readily accessable, but here is seen a great mountain of ore (low grade) where tunnels, drifts, upraises and stopes are not required, in order to extract the ores for shipment to mill or smelter. Knowing that an almost inexhaustable tonnage of ore, carrying small silver and gold values, and an approximate average of 1.3 per cent copper and knowing that the mining of the ore must be done at a very low cost per ton, the major problems of bow to mine, disposition of waste, transportation of ore and milling or concentration presented themselves. Quantity production was essential. Step by step these problems have been successfully met and solved and today you see the operation of one of the most prosperous and also unique mines in the world. There are many interesting facts regarding the property, and a visit to the same is always attractive and full cent copper. The property contained three veins, each dipping about 45 degrees and the main shaft extending to the Mascot tunnel, about 1,200 feet lower, dipped at about the same angle. The other sides of the ore body also sloped so that natural drainage from the surface would go into the ore pockets and on down through the chutes to the tunnel loading station. The dissolving of copper minerals in natural weathering is accomplished largely by ferric sulphate and sulphuric acid, formed by the action of atmospheric oxygen and water on The flow of solutions being properly regulated and perculating through the ore columns, the natural weathering is greatly accelerated, and the descending solution is so enriched that when it reaches the precipitating launders, in the Mascott tunnel, enough copper content is there to make the operation highly profitable. These launders are 3,200 feet in length py-rit- e. having internal cross sections 32 by 32 inches, located in the Mascot tunnel, and additional 1,400 foot .launder lias been installed outside the tunnel. Samuel K. Kellogg is treasurer and general manager and Frederick E. Turner, superintendent. Due to their foresight and courage, the Ohio Copper is on a sound commercial footing, and there are many years of profitable operation, even with copper selling at a much lower price than the present market. . COLUMBIA STEEL. The Columbia Steel, which is growing rapidly and is one of the industries to which all Utah points with pride, is the means of calling direct attention and putting to practical use another portion of Utahs great mineral resources, for all of the iron ore used by the company is fr. m thSt ore comes from th mine Springs, which point is branch of the Los Angele,, Lake railway, running Cedar City and on to the Springs. Here the ( olumi erates the iron mine, the "( system of mining being week about 4,800 tons of on and forwarded to the plant where 10,000 tons a month is made.

The offices of the company are located in the Kearns building, Salt Lake City. THE OHIO COPPER. smqu The Ohio Copper Company, with properties located at Bingham, closed a most successful year. After deductions for all purposes, a net profit of $589,758.33 was shown. A dividend of 5 5 per cent was paid, totalling cents, paid to shareholders. In 1919 a seemingly hopeless outlook confronted the management, for with increasing supply cost, a high labor market and the rapid dropping in the price of copper, the company found itself left with an ore body of great tonnage but of low value, (from .03 to 1.3 per cent copper), and with a mill that even with the flotation process in use, had failed to make a satisfactory recovery, because of the oxidization of a considerable portion of the ore. About 7 million tons of ore had been mined, the best of the ore taken out and milled and so the nature and value of the remainder was pretty well determined. The section mined having a surface area of 1,400 feet by 600 feet, it was estimated that there were 68 million tons of rock, that would average not less than .03 per $144,-656.7- .Jf thes jiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiimiiiiiiiiiiiiiiiiiiiiniiiiiiiiimiiiiiiiiiiiiiiiiiiiiiiiiiiiii UNION ASSAY OFFICE Assayers and Chemists Hoxt I I'lione Wiin.
