PolyMet Mining reports results for period ended March 31, 2021

St. Paul, Minn., May 6, 2021 – PolyMet Mining Corp. TSX: POM; NYSE American: PLM, today reports it has filed its financial results for the three months ended March 31, 2021 and provides a business update.

The company made meaningful progress in litigation, continued its focus on optimization and engineering efforts related to the NorthMet Project, and maintained full compliance with all operating permits during the period, according to Jon Cherry, chairman, president and CEO.

“We are pleased with the rulings we received this spring from the Minnesota Supreme Court, which provide added clarity as we continue to work through the remaining legal challenges to our permits,” Cherry said. “We expect litigation will continue to at least year-end 2021.”

The following is a brief summary of recent cases:

  • In April 2021, the Minnesota Supreme Court overturned a decision by the Court of Appeals that had remanded the Permit to Mine to the Minnesota Department of Natural Resources (MDNR) for an open-ended contested case hearing. Of the many issues decided on by the court, PolyMet prevailed in the vast majority including the key legal challenge of whether state agencies have discretion to hold contested case hearings. However, the court ruled the MDNR must revisit, in a contested case hearing, one element of the expansive Permit to Mine: the effectiveness of bentonite clay capping for eventual closure of the tailings basin. “We expect this hearing will be addressed in an expeditious manner by the MDNR,” Cherry said, noting that the contested case hearing is expected to run concurrent with other litigation that is in progress. Importantly, the Supreme Court also reversed the Court of Appeals’ decision to require contested case hearings on the dam safety permits.
  • In March 2021, the U.S. Environmental Protection Agency (EPA) sought, and the company agreed to, a 90-day review of EPA’s downstream water quality decision under section 401(a)(2) of the Clean Water Act. Because EPA’s downstream water quality determination is a prerequisite for PolyMet’s federal section 404 wetlands permit, the U.S Army Corps of Engineers on March 17 notified the company it had put the permit on hold for the duration of EPA’s review. The company is participating in this review as appropriate. The EPA is expected to issue its determination at the end of the 90-day review period in early June.
  • In February 2021, the Minnesota Supreme Court overturned a decision by the Court of Appeals related to the PolyMet air permit. On the central argument in that case, the Supreme Court held that the lower court had “relied on erroneous interpretation of federal law” when it ruled against PolyMet. The case was returned to the Court of Appeals to resolve a limited number of items the lower court did not specifically address in its original decision. The Court of Appeals will make a decision by late July.
  • To date, PolyMet has received favorable decisions in all six cases that have reached final conclusion – four federal and two state. More information on recent court developments can be found on the company’s website at polymetmining.com/investors/news/ and on its SEDAR and EDGAR profiles.

  • Loss for the three months ended March 31, 2021, was $3.7 million compared with $4 million for the prior year period. The decreased loss was primarily due to reduced spend on studies and evaluation of the mineral resource and on investment gains from restricted deposits.
  • Capital expenditures for the three months ended March 31, 2021, was $1.8 million compared with $2.9 million for the prior year. The decrease was due to lower capitalized spend following receipt of permits in March 2019 as the company awaits resolution of legal challenges to permits.

The financial statements have been filed at www.polymetmining.com and on SEDAR and EDGAR and have been prepared in accordance with International Financial Reporting Standards. All amounts are in U.S. dollars. Copies can be obtained free of charge by contacting the company at 444 Cedar Street, Suite 2060, St. Paul, MN 55101, or by e-mail at info@polymetmining.com.
