Mr. Keith began his career as state geologist for the Arizona Geological Survey and geological mapper for Kennecott's Geological Research Group. In 1979 Exxon Research funded him to research and develop his ideas about ore-forming processes.
In 1983 he co-founded MagmaChem Exploration Inc. as its President for the purpose of developing a chemical classification of igneous rocks and mineral deposits to lower the risk of exploration. The $100 million invested over the years by both mineral industry and oil and gas companies in the development and testing of the MagmaChem approach resulted in the creation of exploration tools that have directly contributed to the discovery of eighteen mineral deposits on three continents, with a total gold and copper metal value of over $60 billion at today's commodity prices.
Mr. Keith has presented and published hundreds of geological papers and is a member and has served as an executive for numerous professional mining associations. |
