Workforce
over 360 full-time operational jobs and 700 jobs during its construction phase.
Overview
The NewRange Project is located in the established Iron Range mining region of northeastern Minnesota and consists of two deposits: NorthMet and Sunrise (formerly Mesaba). The project is currently in the permitting stage. In May 2025, the NorthMet Project was designated as a Transparency Project by the US federal government to prioritise and streamline the federal permitting process.
Production
The NorthMet deposit is planned as an open pit operation. The initial plan for the NorthMet operation is for a processing rate of 32,000 tons per day. NewRange is studying the potential to increase this to 40,000 tons per day.
Processing
The planned processing for the NorthMet project will involve a beneficiation plant and a hydrometallurgical plant. The process will include primary and secondary crushing, a new SAG mill and a new ball mill. Ore will be processed through rougher flotation to produce a bulk copper and nickel concentrate, which will then be reground and separated in a cleaner flotation circuit. The hydrometallurgical plant will involve pressure treatment of concentrates and precipitation of gold and platinum group metals.
Expansion
In partnership with Glencore.
