RI 4113 Gallatin Corundum Deposits, Gallatin Co., Mont.

"INTRODUCTION The Miscellaneous Minerals Division of the War Production Board requested the Bureau of Mines to investigate the Gallatin corundum property as a possible source of corundum, which was in short supply due to the war. The Gallatin corundum property, also known as the ""Fuller mine"", the ""Montana Corundum mine"", and as the ""Old Qorundum mine"" was first examined by a Bureau of Mines engineer 2/ in July 1943. Bureau of Mines work on the property started October 11, 1943, was recessed May 5, 1944, and was resumed in October 1944 when the diamond-drilling program started. The project was completed February 7, 1945. The data obtained are given in this report.The Federal Geological Survey made a reconnaissance survey in the spring of 1943 and mapped the area the following autumn. The results of these surveys are contained in a memorandum report prepared in December 1943.ACKNOWLEDGMENTSIn its program of investigation 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 project as soon as practicable after its conclusion. The Mining Branch, Lowell B. Moon, chief, conducts preliminary examinations, performs the actual investigative work, and prepares the final report. The Metallurgical Branch, R. G. Knickerbocker, chief, analyzes samples and performs beneficiation tests."
