copper, gold, bentonite and barite, primarily open pit with full project scope development including
metallurgical runs. Utilized geochemical zoning and structural controls to expand reserves in all
mining projects to optimize mine planning or construction and quarry operations. A primary
concern was stable pit slopes, underground development, and geotechnical work to ensure
production operations were not disrupted by ground support issues.
 Language familiarity: Spanish 5 years, Vietnamese 3 years, Russian 5 years.
