The cost of managing waste streams – including water, waste rock and tailings – to reduce the environmental impact of mining is a present and future threat to the sector's viability and social license to operate. Critical compliance, avoidance and mitigation measures help address these impacts but drive up capital and operating costs and closure liabilities for both industry and government.
NRC's Environmental Advances in Mining (EAM) program targets these sustainability challenges by developing, demonstrating and validating solutions to problems that drive costs and liabilities of hard rock mining. By engaging the supply chain in the innovation ecosystem we help increase the market share of Canada's mining equipment, technology and services (METS) sector. This means a stronger economy, more jobs and a cleaner environment for Canadians.
Collaborate with us
The massive scale, cost and complexity of mining – from exploration to operations to closure – make the development and introduction of new environmental technologies both risky and expensive.
NRC's multi-year R&D approach connects technology developers, suppliers, integrators and producers in collaborative projects defined with a deeper understanding of end-user requirements, challenges and pathways toward commercialization. Involving the entire supply chain in technology conception and development leads to faster scale-up and adoption, reducing uncertainty and speeding up the environmental permitting process. This de-risks the process while giving all partners a meaningful stake in the benefits of innovation.
The EAM program establishes co-investment opportunities that engage mining equipment and technology suppliers, systems integrators and mine operators in projects targeting industry-defined priorities. Multi partner R&D projects and consortia and individual business arrangements are always negotiated to meet clearly defined client needs and market outcomes.

Technical and advisory services
NRC's competitive advantage lies in its multidisciplinary capabilities, drawing on experience in adjacent aerospace, construction and defence markets to complement our expertise in mining and environmental remediation. By sustaining technical competencies in emerging as well as applied sciences, we are able to meet client needs as they advance along their technology roadmaps, from next generation solutions to market-ready deployment in the field.
Our mining work applies our strengths in biotechnology, process engineering, water treatment, analytical characterization and multi-scale modelling. Our experts are sought after for their technical expertise, experience and innovative approaches to projects depending on materials and process characterization; industrial and chemical engineering; technology demonstration; and the ecological / ecotoxicological impact of contaminants.
NRC clients also gain access to specialized infrastructure and facilities including:
- Powerful materials characterization and microscopy centres, including Scanning Electron Microscope (SEM), Transmission Electron Microscopy (TEM), and X ray diffraction (XRD)
- Laser-Induced Breakdown Spectroscopy (LIBS) and laser ultrasonic labs
- ARD kinetics testing facilities
- Effluent treatment facilities
NRC engages clients on an individual basis and through multi partner collaboration models. Contact us to find out how we can work together to increase market share of Canadian METS and reduce capital and operational expenditures and liability costs.
