Teck Resources, a diversified miner with coal, copper, zinc, and oil sands operations, and Glencore-backed PolyMet Mining, a firm engaged in the exploration and development of natural resource properties, completed the formation of NewRange Copper Nickel, a joint venture located near both existing and closed iron ore mines and utilizes existing brownfield tailings storage and plant locations to minimize environmental impact. Financial terms were not disclosed. "The NewRange Copper Nickel joint venture brings together two large, well defined mineral resources in the established Iron Range mining region of Minnesota. This agreement will help unlock a new domestic supply of critical metals for the low-carbon transition through responsible mining," Don Lindsay, Teck Resources President and CEO.
