Reclaim, remediate, become more resilient

We understand that the mine closure process includes not only rehabilitation but also monitoring and have first-hand experience with long-term performance of closure designs. We know what works at a real mine, and not just on paper. Our experience with closure—whether environmental, regulatory, economic or social—influences our approach. That’s why we consider closure at all stages of mine development and design. We leave you with walk-away solutions and peace of mind. Read More
