PolyMet Mining Corp. TSX: POM; NYSE American: PLM, and its wholly-owned subsidiary Poly Met Mining, Inc. (together PolyMet or the company) announced today that PolyMet has entered into a subscription agreement for the issuance of unsecured convertible debentures (the debentures) of up to USD$30 million with Glencore AG, a wholly-owned subsidiary of Glencore plc (together Glencore).

The debentures are unsecured and will be issued in four tranches throughout the calendar year in 2020, all of which are due on the earlier of March 31, 2023 or upon US$100 million of project financing. Interest will accrue on the debentures at 4% per annum on the balance drawn.

The principal amount of the first tranche issued today is convertible into common shares of the company at a conversion price equal USD$0.2223, which represents a 10% discount to the five-day volume weighted average price on the NYSE American. All subsequent tranches also will be priced at a conversion price equal USD$0.2223. The company may issue a maximum of 134,952,767 common shares upon conversion of the debentures, being approximately 13% of current issued and outstanding common shares.

Funds will be used primarily to advance on-going litigation associated with permits for the NorthMet project, continue engineering and optimization efforts and meet general administrative obligations.

“These funds provide the financial framework to continue to move the NorthMet Project forward while we continue to defend the permits we earned over an exceptionally long and rigorous process led by the state of Minnesota. We appreciate Glencore’s continued commitment to, investment in, and support of the project,” said Jon Cherry, president and CEO.

About PolyMet

The project is located in the established mining district of the Mesabi Iron Range in northeastern Minnesota.

The permits, however, are the subject of ongoing litigation. NorthMet will take advantage of the region’s established supplier network and skilled workforce, is expected to require approximately two million hours of construction labor, will create approximately 360 long-term jobs directly, and generate a level of activity that will have a significant multiplier effect in the local economy.
