Zinc and Lead

Our zinc and lead assets in Canada consist of CEZinc, General Smelting of Canada and Kidd Operations, which share a common history given they were all founded by Noranda Mines Limited.

The CEZinc Refinery in Salaberry-de-Valleyfield, Quebec has been an integral part of the local community since 1963. CEZinc is the second largest zinc refinery in North America and the largest zinc processing facility in eastern North America, where the majority of zinc customers are located. The refinery produces refined zinc metal and various by-products from sourced zinc concentrates.

Founded in 1955, General Smelting of Canada is one of North America’s most established manufacturers of lead alloy anodes for electrowinning, chrome plating and pickling processes along with offering lead construction and maintenance services for electrostatic precipitators and acid plant equipment on a worldwide basis. The plant is based in Lachine, Quebec and employs around 50 people.

Our Kidd Operations in Timmins, Ontario produces zinc and copper concentrates from Kidd Concentrator and the Kidd Mine, the world’s deepest base metal mine below sea level.

Leaving a legacy

The reality of a mining operation is that they do not last forever, so we are proud to leave behind a positive legacy wherever we operate. As an example, our Matagami Mine closed in June 2022, bringing an end to an era that began in 1963. A farewell celebration was in order, so town residents and employees were invited to come together to celebrate a making of history in Matagami.
