Summary of Experience

Mr. Rackley received a BA in 1951 and an MS degree in Geology in 1953 from the University of Tennessee in Knoxville, Tennessee. Following graduation, Mr. Rackley worked in geological, geochemical, and geophysical exploration for New Jersey Zinc Co. in Virginia and North Carolina.

Mr. Rackley began his career in uranium exploration in June 1957, six weeks prior to leading a reconnaissance crew into the Shirley Basin of Wyoming in late July. The geology was deemed favorable and all the men and equipment that Utah Mining could muster descended on Shirley Basin three days later. This crew located mining claims and acquired leases on which the Utah-Pathfinder-Cogema mines were discovered. In 1967, serving as Director of Exploration for Teton Exploration, Div. United Nuclear Corporation based in Casper, Wyoming, Mr. Rackley acquired leases and claims in the Morton Ranch area of the southern Powder River Basin. Mining was underway by the early 1970s.

Along with the discovery of these mines, Mr. Rackley and his associates developed useful theories on the origin of uranium deposits that led to more efficient ways of doing exploration and evaluating properties. These theories were thoroughly researched and a number of professional articles by Mr. Rackley and others have been published. These theories and field experiences were incorporated into the SRI International computer-based Prospector Consultant System in which Mr. Rackley served as Expert - a program financed by The Office of Resource Analysis, U. S. Geological Survey, Reston, Virginia.
