How we close our mines is just as important as how we build and operate them. When done well, mine closure can leave a lasting, positive and sustainable legacy.
We work in partnership with our clients to develop tailored strategies and solutions to streamline closure and meet the multifaceted project objectives and requirements.
We are committed to delivering projects on budget and on schedule, based on ethical and responsible mine reclamation practices that maximize value and minimize risks to local communities and the environment. JDS is currently supporting reclamation scopes in B.C., Yukon, Northwest Territories and Nunavut.
