Pierre LeMieux

Senior Technical Expert, Environmental Scientist

Pierre has dedicated his career to ensuring responsible resource development and reclamation of legacy and abandoned mine sites. He draws insights from a career in which he has worn many “hard hats” across the mining industry, from surveyor to engineer to permitting and compliance specialist.

For more than a decade, Pierre has brought this expertise to public and private clients as a consultant. These clients rely on his guidance for reclamation and site closure planning as well as civil and environmental engineering projects related to mine waste removal, stream and wetland restoration, and stormwater management. A lifelong outdoor enthusiast who grew up in Montana, Pierre brings a practical approach to project management, handling every aspect with a view of the client’s end goals and of broader issues related to resource development and land use.
