PolyMet Statement on Today's Minnesota Court of Appeals Decision

Poly Met Mining, Inc., a wholly-owned subsidiary of PolyMet Mining Corp. (TSX: POM) (NYSE American: PLM) (together PolyMet or the company), issued the following statement regarding today's Minnesota Court of Appeals decision remanding the Company's air permit to the Minnesota Pollution Control Agency for additional explanation supporting its permitting decision.

While disappointed in the court's decision, we stand firmly in our belief that the Minnesota Pollution Control Agency appropriately accounted for the potential effects of the NorthMet Project and will expeditiously provide the supporting explanation requested by the court.

The facts and science that prove the project can meet air quality standards are not in doubt. Copper, nickel, palladium and cobalt are high demand metals for infrastructure projects and the production of electric vehicles and renewable and clean energy technologies including solar panels, wind turbines and batteries. These mineral resources need to be mined to support future clean energy and electric mobility technologies consistent with the priorities of the Biden Administration and as outlined in a June 2021 White House report on vulnerabilities within essential supply chains. Critical minerals such as those PolyMet will produce and large capacity batteries were two of the vulnerabilities identified in the 250-page report.

About PolyMet

PolyMet is a mine development company that owns 100% of the NorthMet Project, the first large-scale project to have received permits within the Duluth Complex in northeastern Minnesota, one of the world's major, undeveloped mining regions. NorthMet has significant proven and probable reserves of copper, nickel and palladium - metals vital to global carbon reduction efforts - in addition to marketable reserves of cobalt, platinum and gold. When operational, NorthMet will become one of the leading producers of nickel, palladium and cobalt in the U.S., providing a much needed, responsibly mined source of these critical and essential metals.

Located in the Mesabi Iron Range, the project will provide economic diversity while leveraging the region's established supplier network and skilled workforce, and generate a level of activity that will have a significant effect in the local economy. For more information: www.polymetmining.com.
