RI 3993 Drum Mountain Manganese Project, Juab County, UT

"INTRODUCTION The manganese deposits of the Drum Mountain area were investigated as two separate projects. The first was begun in November 1940 and completed in August 1941, and the second began in January 1945 and ended in May of the same year. The first project was initiated as part of the Bureau of Mines program for development of strategic minerals for national defense. Subsequent operations disclosed conditions somewhat different than were expected, and it was decided that additional drilling should be done to delimit the ore bearing horizons further.The more promising manganese deposits in the Drum Mountains are situated on properties known as the Staats manganese mine and the Pratt manganese mine. The property controlled by the Pratt interests is under lease to the Ward Leasing Co. The 1941 project investigated the deposits on both properties, whereas the 1945 project was planned to explore further the oxidized ore bodies of the Pratt mine, although one hole was drilled in an attempt to extend the carbonate ore body on the Staats property (fig. 1).ACKNOWLEDGMENTSIn its program exploration of mineral deposits, the Bureau of Mines has as its primary objective the more effective utilization of our mineral resources to the end that they make the greatest possible contribution to national security and economy. It is the policy of the Bureau to publish the facts developed by each exploratory project as soon as practicable after its conclusion. The Mining Branch, Lowell B. Moon, chief, conducts preliminary examinations, performs the actual exploratory work, and prepares the final report. The Metallurgical Branch, R. G. Knickerbocker, chief, analyzes samples and performs beneficiation tests."
