Mining and milling

Our Fraser Mine has deep history in Sudbury having been built in 1963. The complex is situated near the Strathcona Concentrator 55 kilometres northwest of Sudbury. Nickel production began in the 1960s followed by copper production in the 1980s. The anticipated life of mine extends through 2024.

Nickel Rim South (NRS) Mine began production in 2009 and is a nickel, copper and precious metal deposit. The anticipated life of mine extends through 2024. NRS is situated near the Sudbury airport 20 kilometres northwest of Sudbury.

Fraser Mine and Nickel Rim South Mine have been operating since 1963 and 2009, respectively.

Proudly, NRS took home the John T. Ryan Regional Trophy for the Province of Ontario for its safety performance in 2021. Proving that safety and high performance go together, NRS has received industry recognition not only for their safety performance, but also for their operations excellence.

A Five-Star Underground Maintenance Facility

Having a five-star underground maintenance facility is no easy feat, and for Nickel Rim South Mine, part of our Sudbury Integrated Nickel Operations (Sudbury INO), it has been a longstanding commitment.

The Strathcona concentrator receives ore from the two Sudbury mines as well as third-party custom feed ores and produces two concentrate streams – a nickel concentrate that goes to the Sudbury Smelter for smelting and a copper concentrate that goes to Glencore’s Copper business for smelting and refining. The mill has a maximum capacity of approximately 2.75 million tonnes of ore per year.


We are pursuing the Onaping Depth and Nickel Rim South Extension (NRSE) projects, which would extend our presence in the community.

Onaping Depth Project is a nickel/copper resource located within the existing Craig Mine infrastructure. The feasibility study of the project was completed at the end of 2016. The project is currently in the development stage and represents a re-imagining of the future as we go to new depths to attain the resources needed for a lower-carbon economy (view video below). NRSE is a nickel/copper resource located in close proximity to the existing Nickel Rim South Mine infrastructure. It is currently in the study stage (FEL 2/3).
