North America

Our North American offices are located in Denver in the USA and Sudbury, Vancouver and Calgary in Canada.

The Denver office, established in 2008, provides the full range of engineering services from conceptual to detailed engineering of tailings, mine backfill and long distance pipelines, as well as dry stack filtered tailings systems. The office has extensive process engineering experience, as well as specific filtration and thickening expertise. A comprehensive laboratory supports their engineering work.

Our USA Field Services staff, based in Denver, conducts on-site test work and process audits to improve performance of existing operations through upgrades and retrofits. The Vector® was developed by Field Services and they are responsible for the global design and sizing of these units that are retrofitted under supervision of P&C staff at the local mine site.

The Sudbury office, founded in 2010, focusses primarily on mine backfill systems and has broad experience in mining and mine backfill. They have executed numerous detailed engineering designs of mine backfill preparation plants and underground distribution systems and have extensive operational and commissioning expertise. The comprehensive backfill laboratory offers the full suite of backfill characterisation tests.

The Calgary and Vancouver offices work on a diverse range of slurry handling and process projects, including working closely with numerous clients in the oil sands industry.
