KSH has been active in minerals and metals since the early 1990s when it began engineering for the greenfield Aluminerie Alouette plant in Sept-Îles, Qc. KSH was responsible for the design of the anode rodding shop and bath treatment as well as the building for the 215,000 t/y aluminum smelter.

Since then, KSH and its Toronto subsidiary, have worked on a variety of assignments for the minerals and metals sectors.
