Mine Closure and Reclamation
Mine closure is the process of planning for and implementing strategies to transition from mining activities to the future, returning land use. Okane helps mining companies to return land responsibly and safely at the end of a mine’s lifecycle. We leverage over 25 years of international experience in mine closure and waste management to integrate progressive mine closure throughout all phases of mining projects to maximize asset value while achieving positive environmental and social outcomes. Our solutions demonstrate a clear closure roadmap from feasibility assessment through to relinquishment.
