RI 4024 Iron Mountain Beryllium Dep0sits Sierra and Socorro Counties, New Mexico

"INTRODUCTION Geological examination of the Iron Mountain beryllium deposits was begun by a field part 3/ of the Federal Geological Survey in May 1942. Later in that month the occurrence was examined by the author and C. H. Johnson, of the Bureau of Mines, and a preliminary exploratory program was outlined. Trenching and sampling began about June 15 and were completed in July 1942. A large tonnage of beryllium-bearing material was indicate by this preliminary survey, so that additional funds wore allotted for further trenching and sampling, underground exploratory work, and diamond drilling. This later program was initiated in July 1942 and was completed in May 1943. 4/ACKNOWLEDGEMENTSIn its program of exploration of mineral deposits, the Bureau of Mines has as its primary objective the more effective utilisation 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."
