• Demonstrated experience in multidisciplinary estimating.
• Experience with mining projects involving commodities such as gold, silver, copper, lithium, rare earths, iron ore, nickel, ferroalloys, aluminum, cobalt, or potash.
• Sound foundation in generating unit rates for mining processing plant equipment and key bulk commodities.
• Successful completion of an engineering four-year degree, college diploma, or equivalent technical program.
• Excellent understanding of Microsoft Office and advanced knowledge of Microsoft Excel.
• Ability to analyze detailed information and present it at a higher level for reporting, discussion, and presentations.
