Mining Hall of Fame

James Herold Courtright “James Harold Courtright was an extraordinary exploration geologist. He teamed up with his life-long colleague and friend Kenyon E. Richard to produce an exploration record for ASARCO Incorporated that was described in the 1995 Arizona Geological Society Digest 20 as “…the all-time most successful porphyry copper program.”
Kenyon E. Richard  “Kenyon Richard was born in San Francisco and graduated magna cum laude from the University of Nevada, Reno, in 1937. He then joined the E. N. Pennybaker exploration team with Consolidated Coppermines Corp. at Ely, Nevada, as a geologist, and in 1941 he hired Harold Courtright. In 1945, Kenyon and Harold joined American Smelting and Refining Co. in Salt Lake City as exploration geologists. They were destined to become perhaps the most famous and successful team in the history of mineral exploration.”
