ST. PAUL, MINNESOTA--(Marketwired - June 15, 2015) - A correction from source has been issued for the PolyMet press release disseminated today at 5:43 PM ET. The headline incorrectly referred to "Fiscal 2015 Results" where it should have referred to "First Quarter Fiscal 2016 Results." The complete and corrected release follows.

PolyMet Mining Corp. (TSX:POM)(NYSE MKT:PLM) today reported that it has filed its financial results for the three months ended April 30, 2015. PolyMet controls 100 percent of the development-stage NorthMet copper-nickel-precious metals ore-body and the nearby Erie Plant, located near Hoyt Lakes in the established mining district of the Mesabi Iron Range in northeastern Minnesota.

NorthMet is nearing completion of a decade-long environmental review led by the Minnesota Department of Natural Resources, the U.S. Army Corps of Engineers and the U.S. Forest Service as Co-lead Agencies and the U.S. Environmental Protection Agency and three Minnesota Chippewa bands as Cooperating Agencies. 

The financial statements have been filed at www.polymetmining.com and on SEDAR and EDGAR and have been prepared in accordance with International Financial Reporting Standards ("IFRS"). All amounts are in U.S. funds. Copies can be obtained free of charge by contacting the Corporate Secretary at First Canadian Place, 100 King Street West, Suite 5700, Toronto, Ontario M5X 1C7 or by e-mail at info@polymetmining.com.

Goals and Objectives for Remainder of Year to January 31, 2016

• Preparation of permit applications in parallel with the final stages of the EIS.
• Decision on state permits within 150 days of acceptance of applications, under state guidelines.
• Records of Decision on the federal 404 Wetland Permit and the Land Exchange.
