Pinto Valley is an open-pit copper mine located at the west end of the historic Globe-Miami mining district of central Arizona, approximately 80 miles east of Phoenix. Pinto Valley has been in operation since 1972 and has produced more than four billion pounds of copper. Acquired by Capstone from BHP in 2013, the mine is fully permitted through 2039 and a study is underway to potentially extend the mine life through 2050.

Our proximity to the Greater Phoenix metro area provides prospective employees with the option to live in communities such as Mesa, Apache Junction, Gilbert, Chandler, San Tan Valley, or Florence. Our location offers a unique work-life balance, blending the rewarding opportunities of the mining industry with easy access to the vibrant energy of Downtown Phoenix, making it an ideal choice for both individuals and their families.

• Strong communication, organization, problem-solving, and analytical skills.
• Ability to work outdoors and in ambient weather conditions.
• Valid State Driver’s License.
• Able to speak, comprehend, read, and write English.

Position Responsibilities

• Demonstrate safety leadership and safety consciousness in all field, office, and project activities.
• Complete structured rotations through Mine Operations, Mine Engineering, Geology, and Geotechnical functions, with increasing responsibility as capability develops.
• Spend time in the field with mine supervisors, dispatch, equipment operators, engineers, geologists, and geotechnical personnel to understand how mine plans are executed safely and practically.
• Support daily, weekly, and longer-range mine planning activities, including production tracking, plan compliance, reconciliation, haulage review, and communication of risks or constraints.
• Assist with mine design and engineering tasks such as bench access, haul road layouts, dump planning, drill and blast interfaces, material movement tracking, and operational improvement projects.
• Support Mine Operations by helping understand plan priorities, constraints, equipment interactions, and opportunities to improve execution against the plan.
• Support Geology with ore control, sampling, mapping, blast-hole data review, ore/waste routing, stockpile tracking, and reconciliation between geology models and production results.
• Support Geotechnical with pit inspections, slope monitoring, ground hazard identification, TARP implementation, geotechnical data review, and communication of slope-related risks to operations and planning.
• Collect, analyze, and summarize operational and technical data using approved tools and formats; communicate results clearly to engineers, supervisors, and mine leadership.
• Participate in improvement projects during each rotation and present key findings, recommendations, and lessons learned to site leadership.

Work Environment The Graduate Engineer will work in both office and field environments. Time allocation will vary by rotation; Mine Operations and Geotechnical rotations are expected to include significant field exposure, while Mine Engineering and Geology rotations may include a higher percentage of office-based technical work. The role requires regular interaction with active mining areas, field inspections, operational meetings, and technical planning activities.
