PolyMet will be the first to commercially mine copper, nickel and precious metals in the world-class Duluth Complex. Located within Minnesota’s Mesabi Iron Range, the NorthMet project features three significant assets: the deposit itself, the former LTV Steel processing facilities which will be rehabilitated for this project, and the infrastructure including existing rail, roads, utilities and established supplier networks. The NorthMet deposit will be mined by open pit methods to a depth of approximately 700 feet below surface.
Work at PolyMet is about being part of a tradition of excellence in Minnesota Iron Range mining that has anchored the economy for generations.
Responsible development
We will produce essential metals in full compliance with strict federal and state environmental regulations.
Processing facility
This existing processing facility will be reopened as part of our NorthMet project, creating much needed regional jobs.
Reusing facilities
The NorthMet project is reusing existing infrastructure of the former LTV Steel taconite processing site.
Project Infrastructure
The existing infrastructure that PolyMet will reuse is a great asset and a huge advantage to the project.
NorthMet location
The NorthMet project is located within Minnesota’s established Mesabi Iron Range mining district.
