Intern, Mine Planning (Summer 2027)

The Martin Marietta Summer Mine Planning Internship provides students with meaningful, hands-on experience supporting mine planning, geological modeling, resource evaluation, and operational improvement initiatives. This approximately 10-week program offers the opportunity to apply classroom knowledge to real-world mining projects while developing technical, analytical, project management, and leadership skills. Working alongside mining engineers, geologists, and operations leaders and reporting to members of the Mine Planning team, Mine Planning Interns gain exposure to both short-term and long-range mine planning activities across Martin Marietta's aggregate operations. Interns contribute to projects that support operational efficiency, resource optimization, geological analysis, and strategic mine development while gaining a deeper understanding of how mine planning supports safe, efficient, and sustainable operations.
