PolyMet announces commencement of the Rights Offering and trading dates

St. Paul, Minn., June 5, 2019 – PolyMet Mining Corp. (“PolyMet” or the “company”) (TSX: POM; NYSE American: PLM) has commenced its previously announced offering of rights (“Rights”) to purchase common shares of the company to raise approximately US$265 million in gross proceeds (the “Rights Offering”).

The Rights trade on the Toronto Stock Exchange (“TSX”) under the symbol “POM.RT” and will cease trading on the TSX at noon (Eastern time) on June 26, 2019. The Rights also trade on the NYSE American under the symbol “PLM.RT” and the last day of trading on the NYSE American will be June 21, 2019.

Pursuant to the Rights Offering, all eligible registered shareholders of PolyMet (subject to applicable law) have been distributed one Right for every common share of PolyMet owned on the record date of June 3, 2019.  For each one (1) Right held, holders are entitled to acquire 2.119069 common shares of PolyMet at US$0.3881 per share (the “Rights Price”).  The Rights Offering includes an additional subscription privilege entitling holders of Rights who have fully exercised their Rights to subscribe for additional common shares, if available, that were not otherwise subscribed for under the Rights Offering.

Subject to applicable law, all PolyMet shareholders have the choice to participate and, by exercising all of their Rights, maintain their existing levels of ownership. Rights holders can, in whole or in part, exercise their Rights and subscribe for common shares, or sell or assign their Rights to another party (who wishes to subscribe for new PolyMet common shares).  The expiry time (the “Expiry Time”) of the Rights Offering is 5:00 pm (Eastern time) on June 26, 2019 (the “Expiry Date”).  Rights not exercised before the Expiry Time on the Expiry Date will be void and of no value.

As previously disclosed, PolyMet has entered into a standby purchase agreement (the “Standby Purchase Agreement”) pursuant to which Glencore AG (“Glencore”), subject to certain terms and conditions and limitations, has agreed to exercise its basic subscription privilege in full and to purchase at the Rights Price, that number of common shares equal to the difference, if any, of (x) the total number of common shares offered pursuant to the Rights Offering minus (y) the number of common shares subscribed for pursuant to the basic subscription privilege and the additional subscription privilege. As a result, subject to the satisfaction of the terms and conditions of the Standby Purchase Agreement, the Rights Offering will be fully backstopped by Glencore.
