NEWS RELEASE 2011-2

POLYMET ANNOUNCES FISCAL 2011 THIRD QUARTER RESULTS

Hoyt Lakes, Minnesota, January 17, 2011 - PolyMet Mining Corp. (TSX: POM; NYSE-A: PLM) (“PolyMet” or the “Company”) reported today its financial results for the three months ended October 31, 2010, which have been filed at www.polymetmining.com and on SEDAR. All amounts are in U.S. funds.

PolyMet controls 100% 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.

Highlights

• At October 31, 2010 PolyMet had cash and cash equivalents of $4.994 million compared with $2.926 million at October 31, 2009. After October 31, 2010, the Company agreed to sell 15 million shares of common stock to Glencore AG ("Glencore") at $2.00 per share for anticipated net proceeds of $28.8 million.

• During the nine months ended October 31, 2010, PolyMet repaid $1.500 million notes payable to Cliffs Natural Resources, Inc. related to the acquisition of the Erie Plant.

• Third quarter loss for the three months ended October 31, 2010 was $210,000 compared with $841,000 in the prior year period. General and administrative expenses were $378,000 for the quarter compared with $883,000 for the prior year period. Excluding a one-time non-cash reversal of prior accrual of stock-based compensation in the latest quarter, general and administrative expense was $581,000 compared with $786,000 for the prior period (excluding a non-cash charge of $97,000 for stock-based compensation during that period).

For the nine months ended October 31, 2010 we reported a loss of $3.563 million compared with $2.858 million in the prior year. The increase in the loss for the period was primarily attributable to writing-off deferred financing costs related to the advisory services provided by BNP Paribas Loan Services ("BNPP"), of which $1.197 million was the fair value of warrants issued. Excluding this write-off and non-cash stock-based compensation, general and administrative expense totaled $2.222 million for the nine months ended October 31, 2010, compared with $2.099 million in the prior year period.
