1987-2011: Economic Geologist and Hydrogeologist.

Economic Geology: Mine and exploration geology of gold, tellurium, uranium and base metals using surface mapping, GIS, geochemistry, geophysics, and drilling for mining and environmental purposes. Evaluated deposits and prospects in disseminated, vein, porphyry, massive sulfide and skarn environments in Nevada, Alaska, British Columbia, Yukon, Peru, Newfoundland, Turkey, Yemen, Eritrea, Ethiopia, New Mexico, Arizona, Utah, Colorado, Idaho, and Washington for individual and corporate clients. Some natural gas exploration in California

Hydrogeology: Research in the Truckee, Carson, and especially the Walker drainages of the western Great Basin. Established environmental criteria and a hydrogeologic model of the Walker River Basin. Prepared historical and projected water budgets under different scenarios for Mason Valley, Campbell Valley, Walker Lake, and in general for the Walker River Basin using precipitation, flow, use, storage, and loss factors. Press releases and materials from public talks are available.

1974-1986: Economic Geologist. Western United States. Precious metals, uranium, and base metals in Tertiary, Mesozoic, Paleozoic, and Precambrian rocks. Managed exploration-deposit development of Borealis Gold District, including discovery of five additional economic gold deposits (1980-1983). Discovered a Jurassic sedimentary uranium deposit in 1977. Employers: Bear Creek Mining Company and Duval Inc.-Tucson AZ (1974-1975), Houston Oil and Minerals Inc. - Denver CO (1976-1983), and St. Joe Minerals Inc. - Tucson, AZ (1984-1986).
