PolyMet and Glencore Agree to Extend Term of US$34.2 Million Convertible Debentures and Amend Share Purchase Warrants

ST. PAUL, MINNESOTA--(Marketwired - July 31, 2015) - PolyMet Mining Corp. ("PolyMet" or the "Company") (TSX:POM)(NYSE MKT:PLM) - today announced that it has renegotiated its convertible debentures with Glencore AG, a wholly-owned subsidiary of Glencore plc (together "Glencore") to extend the maturity date of the outstanding securities issuable under the debenture financing.

Between October 2008 and September 2009, PolyMet issued to Glencore four debentures (the "Debentures"). The initial principal of the Debentures is US$25 million with US$9.240 million of capitalized and accrued interest as of July 31, 2015. At maturity the initial principal and capitalized interest will be exchanged into common shares of PolyMet at US$1.2920 per share through exercise of the "Exchange Warrant".

The agreed amendments, which are subject to approval from the NYSE MKT and the Toronto Stock Exchange for the listing additional shares, are as follows:

The "Maturity Date" of the Issued Debentures has been extended to the earlier of:
i) PolyMet giving Glencore ten days' notice that PolyMet has received permits necessary to start construction of the NorthMet project and availability of senior construction finance, in a form reasonably acceptable to Glencore (the "Early Maturity Event"), and
ii) March 31, 2016.

Previously the Maturity Date was the earlier of the Early Maturity Event and September 30, 2015.

The interest rate has been adjusted to US$LIBOR plus 8% from US$LIBOR plus 4% as of August 1, 2015.
The terms of warrants giving Glencore the right to purchase 6,458,001 common shares of PolyMet have been amended such that the exercise price has been reduced to US$0.9292 per share, being the greater of the market price and the 5-day volume weighted average price ("VWAP"), from US$1.3007 per share. The warrants may be exercised at any time until December 31, 2016 (previously December 31, 2015) subject to mandatory exercise if the 20-day VWAP of PolyMet common shares is equal to or greater than 150% of the exercise price and occurrence of the Early Maturity Event. The exercise price of the warrants and the number of warrants are subject to conventional anti-dilution provisions.

PolyMet president and CEO Jon Cherry stated, "Extending the maturity date to the earlier of permits and construction finance or March 31, 2016 from September 30, 2015 ties with the State's schedule for its adequacy determination and Record of Decision in early February, 2016. These amendments also demonstrate Glencore's continued support for PolyMet and the NorthMet Project as we progress through completion of the environmental review and permitting into construction and operations."

Glencore currently holds 78,724,821 common shares of PolyMet representing approximately 28.5% of PolyMet's issued and outstanding common shares.

As a result of the extension of the Exchange Warrant, the number of common shares issuable to Glencore under the Exchange Warrant would increase by 1,609,426 to 28,110,693 at March 31, 2016 (assuming US$ LIBOR at 1.0%), and which, if exercised, would result in Glencore holding 106,835,515 common shares representing approximately 35.1% of the outstanding common shares of PolyMet (assuming no other shares committed under existing compensation agreements were issued by PolyMet.)

Including 6,458,001 shares issuable upon exercise of other warrants held by Glencore but excluding issuance of shares committed to others under existing share compensation agreements, Glencore would hold a total of 113,293,516 common shares representing approximately 36.4% of PolyMet's partially diluted common shares (again assuming no other shares committed under existing compensation agreements were issued by PolyMet.)

Glencore's decision to enter into the Financing Amendments was made for investment purposes. Glencore will continue to review its investment alternatives from time to time and may determine to increase or decrease its equity ownership in PolyMet through the acquisition or sale of additional outstanding common shares or other securities of PolyMet through open market or privately negotiated transactions in accordance with applicable securities laws.
