From rock to metals
Responsibly producing the building blocks of modern society
PolyMet Mining Corp. is a publicly-traded mine development company focused on permitting, building and operating the NorthMet copper-nickel precious metals project through its wholly owned subsidiary, Poly Met Mining, Inc., a Minnesota corporation.
Our corporate office is in Toronto, Ont., our executive office is in St. Paul, Minn., and our operation headquarters is in Hoyt Lakes, Minn. Through long-term mineral leases, we control the NorthMet copper-nickel-precious-metals ore body. The ore body is located near the Mesabi Iron Range, northeastern Minnesota’s well-established 100-mile-long mining district.
We also own and will refurbish and reuse the Erie Plant and associated infrastructure on the former LTV Steel Mining Company site, which was originally built to process taconite. The site, idle since 2001, is located about six miles west of the NorthMet ore body.
State and Federal agencies have completed a comprehensive environmental review and we have begun the permitting process to develop the new mine and restore existing facilities. Our plan includes using modern mining and processing techniques to minimize environmental effects while creating jobs, generating tax revenue, and ultimately producing the metals we need in everyday life.
PolyMet Mining is committed to building the project to strict standards, meeting or exceeding all applicable state and federal environmental regulations, ensuring a safe work environment, and protecting Minnesota’s beauty and natural resources.
We comprise a team of experienced professionals, most of whom live in Minnesota. We care deeply about the state and are passionate about our work. Many of us are third- and fourth-generation miners, the benefactors of Minnesota’s abundant mineral resources. We work in the same area where we raise our families and hunt, fish and play, and care deeply about how this project will be built and operated.
