Golder Associates is an international group of consulting companies specializing in mining, geotechnical engineering, environmental science, water resources engineering and applied geosciences.
Integrated earth, energy and environmental consultancy
With nearly 50 years of history, Golder understands the mining business. We partner with our clients throughout a mine’s lifecycle to overcome the cultural, environmental, geological and engineering challenges. Golder offers integrated sustainable solutions that balance the needs of the environment and society from existing to complex projects, extreme weather and remote locations.
With our technical expertise, we are committed to finding innovative approaches that serve the global mining industry in the safe, responsible development of mineral resources that support sustainable societies.
Mine planning and development consulting
Golder’s ore evaluation service group offers all levels of studies, technical audits, due diligence reviews and public reports for mineral project development, mine planning and mining operations. We help project sponsors and financial clients manage risks to protect their investments, while supporting business objectives through the solid technical understanding of exploration programs, geological data interpretation and modelling, and statistical and geostatistical analysis. Planning and development also integrates mine engineering, rock mechanics, cultural and environmental matters.
Our global network of qualified persons issue reports under National Instrument 43-101 (Canada), JORC Code 2004 (Australia) SAMREC (South Africa), PERC (Europe) and SEC Requirements (US).
Mine operations consulting
We use an integrated system approach for mine operations that considers the relationships between the various factors such as water resources, energy supply and efficiency, facility location, infrastructure, waste management, closure, environmental compliance and cost efficiency. We are able to isolate the solutions into a single, comprehensive plan that minimizes impacts during mining, reduces liabilities and maximizes recovery.
Comprehensive mine consulting services
Our technical core competencies have provided our clients with assured confidence in their project operations. Key hydrogeologists are supported by specialists in related disciplines such as hydrology, water treatment, ecology, civil and geotechnical engineering, landscape architecture and environmental impact assessment.
This is matched with comprehensive consulting solutions for management of mine waste disposal facilities, site selections, tailings’ dams, waste rock dumps, acid rock drainage, mine rehabilitation, construction and tailings’ re-mining.
Mine closure and reclamation consulting
Golder recognizes the importance of the decommissioning phase of a project just as much as the pre-feasibility and planning stages. Our design-for-closure approach combines current technologies and practical strategic solutions to achieve physical, chemical, and biological stability within each mine component, during operations and in the longer term.
We consider all aspects such as native title and cultural heritage, baseline studies, permit and licence applications, ecological studies, hydrogeochemical investigations, water treatment and mine closure at the design stage. By combining these efforts as part of our impact assessment, we address the environmental and socio-economic issues before they become risks to the project.
Open pit and underground rock mechanic services
We combine the latest instrumentation and computer analysis with pragmatic, experience-based judgement to provide our clients with superior outcomes that meet safety and regulatory needs while providing practical solutions for efficient ore extraction for base metals, precious metals and industrial minerals.
Geological, geotechnical, water modelling and mine software tools
Golder has access to a comprehensive suite of geological, geotechnical, water modelling and mining software tools to assist in the effective management, interpretation and presentation of geological data. This includes acQuire for drill hole data management; Isatis for geostatisical modeling; Vulcan for geological modeling and pit design; and Whittle for pit optimisation.
