ST. PAUL, MINNESOTA–(Marketwired – Oct. 28, 2016) – PolyMet Mining Corp. (“PolyMet” or the “Company”) (TSX:POM)(NYSE MKT:PLM) announced today that it has completed its previously announced private placement with Glencore AG, a wholly-owned subsidiary of Glencore plc (“Glencore”). The Company issued to Glencore 14,111,251 units (the “Units”) at a price of $0.75 per Unit for gross proceeds of $10.6 million. All amounts are in U.S. funds.

The Units were purchased by Glencore pursuant to its right to maintain its pro rata ownership following the private placement that closed on October 18, 2016 comprising 22,000,167 Units placed by Paradigm Capital Inc. for gross proceeds of $16.5 million and 3,963,000 Units placed directly by the Company for gross proceeds of $3.0 million. All Units were issued on the same terms.

The sale of Units to Glencore was in a private transaction that is exempt from the registration requirements of the U.S. Securities Act of 1933 as amended. Each Unit consists of one common share and one half of one common share purchase warrant, each whole warrant exercisable for one common share at a price of $1.00 per share for a period beginning 6 months following the issue date and ending 60 months after the issue date, subject to acceleration in certain circumstances.

Glencore holds $40.0 million secured convertible debentures and $62.440 million secured non-convertible debentures, including initial principal and interest capitalized through September 30, 2016. The private placement triggered an adjustment to the conversion price of the secured convertible debentures from $1.2920 per share to $1.2696 per share. PolyMet also issued to Glencore warrants to purchase 625,000 Common Shares at $0.7797 per share as an incentive for the previously-announced extension of the maturity date of the convertible and non-convertible debentures held by Glencore to March 31, 2018 or such earlier time if it is prudent for the Company to repay the debentures.

As a result of these transactions, PolyMet now has 317,930,624 shares issued and outstanding of which Glencore owns 92,836,072 shares or 29.2%. PolyMet has issued warrants to purchase an additional 27,780,213 shares exercisable at an average price of $0.9499 per share, of which 14,138,627 shares with an average exercise price of $0.9095 are held by Glencore. Upon conversion of the secured convertible debentures, Glencore would receive an additional 31,505,866 common shares. PolyMet has also issued incentive options and restricted stock units for a total of 20,377,106 common shares.

On a fully diluted basis, PolyMet would have 397,593,809 shares issued and outstanding of which Glencore would own 138,480,565 shares or 34.8%. Upon conversion of the secured convertible debt and exercise of all outstanding warrants and options, PolyMet would receive $47.9 million cash in addition to the $29.0 million net proceeds from the private placements and conversion of $40.0 million of debt.

“Completion of this financing is important for PolyMet as we proceed through the state’s decisions on permitting for the NorthMet Project,” stated Jon Cherry, PolyMet president and CEO.

“I am very pleased with the continued support of Glencore and other long-term shareholders along with new shareholders that Paradigm Capital brought to the table,” Cherry concluded.
