Hi, I’m Jonathan (JT) Croston, Director of Mining here at Trace Associates. We work with mining clients of various sizes ranging from private locally owned businesses to major international companies. We consult across a variety of mining sectors, including critical minerals, base and precious metals, uranium, coal, potash, oilsands, aggregates, etc., primarily within Canada.
We help mining companies reduce environmental risk, optimize waste containment, and meet regulatory requirements so they can operate confidently, protect their reputation, and achieve sustainable closure outcomes. Our integrated approach ensures projects are delivered efficiently, with solutions that minimize long-term liabilities and support success through all phase of the mine's life.
Our mining engineering and environmental teams are leaders in the industry, with more than 30 years of experience on mine waste containment and mine remediation/reclamation projects. We can support these types of projects from concept (options assessments) to project execution (issue-for-construction packages and monitoring support).
