Discovered and mined for its high grade ore' prior to 20 years ago, the Chief No. 1 mine at Eureka, Utah, is once again adding its metals to the state's total. During 1943 the main production of the Chief Consolidated Mining company came from the Chief No. 1 mine in the dewatered area between be-tween the 1.S00 and 2,100-foot levels, for the reason that the principal values contained in these ores were zinc and lead, most needed need-ed for war production, the company's com-pany's annual report states. Herein is concrete testimony of how scientific improvements coming com-ing from within the metal mining industry in-dustry are providing for the treatment treat-ment of lower grade ores, thereby making mineable more of the state's resources and reopening old mines as well as new mines. Realizing that Utah's ore reserves are largely low grade, mining and smelting com panies are continually striving to improve their methods of operation and treatment of ores with the view of perpetuating the life of the industry. in-dustry. . , ' Continuing the Chiefs report St"As stated in a former report, there are six ore runs making below the water level and these, years j ago were mined selectively for the lead only as zinc at that time was a detriment to lead smelter operations, opera-tions, and therefore, the mines j were penalized for its content while now by improved methods of notation causing the zinc separation separa-tion from the lead, both metals are recoverable, and it is this ore that is the major portion of our present tonnage, being left there some twenty years ago after the higher grades, by selective mining had been discontinued on account, of the I low metal prices existing at that time." 1 |
