NEWS RELEASE 2023-07


         PolyMet Mining reports results for period ended March 31, 2023         
St. Paul, Minn., May 11, 2023

-
PolyMet Mining Corp. ("PolyMet" or the "company") TSX: POM; NYSE American: PLM,
today reports its financial results for the period ended March 31, 2023 and 
provides a business update.
The company achieved three major milestones during the period:

 *  Closed on the joint venture agreement (the "Joint Venture") with Teck 
 Resources Limited ("Teck"). Under the Joint Venture, named NewRange Copper 
 Nickel LLC ("NewRange Copper Nickel"), the NorthMet and Mesaba deposits 
 containing high-demand copper, nickel, cobalt and platinum group metals (PGM) 
 are under single management with PolyMet and Teck each holding a 50% 
 interest. NorthMet and Mesaba represent two of the largest undeveloped clean 
 energy mineral resources globally. The partners committed to an initial work 
 program for NewRange Copper Nickel with an estimated budget of $170M to, 
 among other things, maintain permits, update feasibility study estimates, and 
 undertake detailed engineering to position NorthMet for a development 
 decision following permit clearances;

 *  Completed an offering of rights to holders of common shares of the company 
 raising approximately $195M in gross proceeds (the "Rights Offering") to fund 
 PolyMet's share of the above-named work program for NewRange Copper Nickel 
 and certain other corporate activities, including repayment of Glencore AG 
 ("Glencore") indebtedness. The Rights Offering was fully backstopped by 
 Glencore, which now holds approximately 82% of PolyMet shares; and

 *  Completed the Permit to Mine contested case hearing on the effectiveness 
 of bentonite clay at the tailings impoundment. The Administrative Law Judge 
 in the case has indicated his intention to rule on the matter by late summer. 
 The Permit to Mine is one of only three permits remaining on hold for 
 additional process. Decisions are pending on all three permits.

Deficiency as at March 31, 2023 primarily due to the $87.6 million convertible 
debt and $10.3 million promissory note with Glencore due upon closing of the 
Rights Offering. The Rights Offering closed April 6, 2023 and all debt was 
fully repaid with the proceeds. The company estimates that it had 
approximately $100 million in available funds after Rights Offering costs and 
debt repayment. Further, Glencore has committed to provide financial support 
to enable the company to continue its business operations through at least 
March 31, 2024.

 *  Loss for the three months ended March 31, 2023 was $5.3 million compared 
 with $8.6 million for the prior year. The decrease was primarily due to a 
 gain on the NewRange Copper Nickel transaction partially offset by 
 transaction costs necessary to close.



 *  Cash provided by investing activities for the three months ended March 31, 
 2023 was $7.4 million compared with cash used of $2.2 million for the prior 
 year. The increase in cash provided was primarily due to proceeds received in 
 connection with the NewRange Copper Nickel transaction.

PolyMet Disclosures
This news release contains certain forward-looking statements concerning 
anticipated developments in PolyMet's operations in the future. Forward-looking 
statements are frequently, but not always, identified by words such as 
"expects," "anticipates," "believes," "intends," "estimates," "potential," 
"possible," "projects," "plans," and similar expressions, or statements that 
events, conditions or results "will," "may," "could," or "should" occur or be 
achieved or their negatives or other comparable words. Forward-looking 
statements relate to future events or future performance and reflect 
management's expectations or beliefs regarding future events including, but 
not limited to, statements with respect to the anticipated benefits of the 
50/50 joint venture and the company's expectations with respect to the future 
development of NorthMet and Mesaba. Forward-looking statements address future 
events and conditions and therefore involve inherent known and unknown risks 
and uncertainties. Such risks and uncertainties include, but are not limited 
to, among other things, receipt of regulatory approvals, timing of closing, 
the outcome of the development of the NorthMet and Mesaba projects, and the 
outcome of any financing required to raise the funds for PolyMet's share of 
the initial work program and Glencore's funding commitment. Actual results may 
differ materially from those in the forward-looking statements due to risks 
facing PolyMet or due to actual facts differing from the assumptions 
underlying its predictions.
PolyMet's forward-looking statements are based on the beliefs, expectations 
and opinions of management on the date the statements are made, and PolyMet 
does not assume any obligation to update (except as required by law) 
forward-looking statements if circumstances or management's beliefs, 
expectations and opinions should change.
Specific reference is made to risk factors and other considerations underlying 
forward-looking statements discussed in PolyMet's most recent Annual Report on 
Form 40-F for the fiscal year ended December 31, 2022, and in our other 
filings with Canadian securities authorities and the U.S. Securities and 
Exchange Commission.
The Annual Report on Form 40-F also contains the company's mineral resource 
and other data as required under National Instrument 43-101.
No regulatory authority has reviewed or accepted responsibility for the 
adequacy or accuracy of this release.
