COMPANY OVERVIEW

PolyMet Mining Corp. is a Canadian mine development company focused exclusively on the NorthMet copper-nickel-precious metals project through its wholly owned subsidiary, Poly Met Mining, Inc., a Minnesota corporation. PolyMet’s corporate office is in Toronto, Canada with executive offices in St. Paul and operational headquarters in Hoyt Lakes, Minnesota. Through a long-term lease, the company controls the NorthMet copper-nickel-precious metals ore body. The deposit is located in the Mesabi Range, northeastern Minnesota’s established mining district, and stretches approximately 2.5 miles.

PolyMet also owns and will refurbish and reuse the Erie Plant, a former taconite processing facility located some six miles from the deposit.

The NorthMet project is in the midst of a comprehensive environmental review and permitting process to develop a new mine and restore an existing mining facility. PolyMet’s proposal includes using modern mining techniques to minimize environmental impacts while creating jobs, generating tax revenue and, ultimately, producing the metals we need in everyday life.

PolyMet’s commitment is to design, build and operate the NorthMet project in a way that protects the surrounding environment, fosters a healthy, safe and rewarding work environment, and creates value for all our stakeholders.

Our team includes many third- and fourth-generation miners – people whose experience in environmentally responsible mining demonstrates our commitment to investing in the health of our region and making this a great place to live for generations to come.
