Multi-cultural work experience in geology, economic analysis and environmental management includes tours of duty at 3 universities, 6 mining companies, and 2 government agencies since 1974. I coordinate complex interdisciplinary projects involving teams of up to 20 specialists for mineral resource appraisal. Have managed or investigated projects in all western United States, Canada, Mexico, Chili and Honduras.
I have a unique combination of geologic modeling, economic evaluation and ArcGIS map making skills. These skills have been applied to research in mining districts throughout California for the past 34 years. This experience has formed of my theories of ore deposit genesis, means of exploring for them, and appraisal methodologies for evaluating them. I also have extensive exploration in the cleanup of abandoned mine sites and served as project manager for CERCLA actions at the Klau-Buena Vista Superfund Site. I have also lead several interdisciplinary teams. I am an expert in environmental permitting and land use planning, and geologic applications for ArcGIS technologies.

Coordinator for geophysical surveys and studies (seismic, resistivity, induced polarization, SP, magnetometer). Write reports and perform technical review of reports prepared by Resource Area geologists for mineral appraisals, land exchanges, conveyances, mineral sales and leases, wilderness withdrawals, mining claim occupancy trespass, surface use determinations, CERCLA removal or remediation, water quality remediation, and hazardous abandoned mine closures. Make technical recommendations mineral land classifications, appraisals and sales. Make geologic and hydrologic recommendations for the location of water wells and compliance with TMDL standards. Make and maintain inventories of mineral deposits, abandoned mine lands sites, impaired watersheds, TMDL non-compliance sources, and lead projects to manage or remediate them. Track expenditures, workload accomplishments and budget. Develop project and office Annual Work Plans.
