Other minerals

Specialised and comprehensive commodity expertise from initial geology to closure and reclamation.

Known for our ability to execute projects in remote and challenging locations, we are one of only a handful of companies in the mining industry that provide a comprehensive mineral resource development service from the resource definition stage through project implementation and into operational capital improvements. Our specialised commodity capability, operations and consulting expertise are applied to assess deposits, supervise pilot-plant and metallurgical testing, conduct feasibility studies, and prepare efficient and cost-effective mine and plant designs. We have strong market positions in many specialised commodities, a few of which are highlighted below.

Uranium

As one of the world’s leading providers of engineering and construction services to the uranium mining and processing industry, we have contributed to the successful development of uranium projects from initial geological interpretation to closure and reclamation.

With our depth of knowledge and experience in process engineering, we can identify the optimum process route for a particular uranium deposit based on a number of variables such as ore type, mineralogy, gangue composition, impurities and project location. We have extensive experience in the various approaches to processing uranium ores, including comminution, pre-concentration, leaching, solid-liquid separation, solvent extraction (SX), solid ion exchange (IX) and product precipitation and handling.

Our extensive experience has been gained on uranium projects in Canada, Africa and Australia. For more than 30 years, we have worked in Saskatchewan, Canada, providing services on the Rabbit Lake, Cigar Lake, McClean Lake, McArthur River and Key Lake operations. Additional experience includes:

• Husab uranium project, Namibia (EPCM in joint venture)
• Mulga Rock Uranium project, Western Australia (study)
• Langer Heinrich uranium project, Namibia (definitive feasibility study (studies, EPCM))
• Etango uranium project (heap leach), Namibia (study)
• Beverly Four Mile project (in situ), Australia (study)

Coal

From managing exploration and testwork through to mine planning, design and EPCM, we have decades of experience at coal mines in the US, Canada, Mexico, Australia, South Africa, Botswana, Indonesia, New Zealand and Colombia. Our specialised knowledge in coal orebody assessment, mine planning and design, material handling and transportation, and processing is complemented by our unsurpassed experience in designing, building and operating mining projects worldwide. We also have comprehensive expertise in tailings and waste management, geotechnical engineering, hydrogeology and environmental services for coal mines.

Select experience includes:

• Quintette, British Columbia (study)
• Grande Cache, Alberta (technical reporting, NI 43-101)
• Paz del Rio, Colombia (studies and technical reporting)
• Morupule, Botswana (studies)
• Vele, South Africa (study)
