PolyMet Reports Fiscal 2013 Results

Hoyt Lakes, Minnesota, April 23, 2013 – PolyMet Mining Corp. (TSX: POM; NYSE-MKT:PLM) (PolyMet or the Company) today reported that it has filed its financial results for the year ended January 31, 2013. 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.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.


  • Loss for the year ended January 31, 2013 was $6.626 million compared with $3.045 million for the prior year period. General and administrative expenses excluding noncash stock-based compensation in the year ended January 31, 2013 were $3.653 million compared with $2.744 million in the prior year period, excluding non-cash stock based compensation. Salaries and benefits increased by $0.730 million to $1.394 reflecting expansion of corporate staff.
  • At January 31, 2013 PolyMet had cash and cash equivalents of $8.088 million compared with $17.478 million at January 31, 2012. Since then, PolyMet has received a $20 million loan and has announced that it plans to issue a $60 million Rights Offering with a standby commitment from Glencore International plc for approximately $53 million. Ona pro forma basis, adjusting for the Rights Offering (including repayment of the $20 million loan) PolyMet would have cash and equivalents of approximately $67 million net of standby fees payable in connection with the Rights Offering.
  • PolyMet invested $18.404 million into its NorthMet Project during the year ended January 31, 2013, compared with $16.137 million in the prior year period. The year ended January 31, 2013 included $2.092 million for purchase of wetland restoration properties. The prior year period included $3.420 million from the sale of equipment the Company no longer plans to use and $4 million for purchase of land funded with proceeds from an Iron Range Resources and Rehabilitation Board loan.
  • In the year ended January 31, 2013, PolyMet recorded a $31.8 million non-cash provision related to its indemnification of Cliffs Natural Resources, Inc. (“Cliffs”) environmental liabilities at the Erie Plant. Under a consent decree between Cliffs and the Minnesota Pollution Control Agency (“MPCA”), Cliffs agreed to mitigate some alleged violations on the property. In October 2012, the MPCA responded to long-term mitigation plans submitted earlier in the year. While there is substantial uncertainty relating to the applicable water quality standards, engineering scope and responsibility for the financial liability, the MPCA’s response to the plans submitted now provides sufficient guidance to allow the Company to estimate of the liability under IFRS, PolyMet has included its best estimate of these liabilities.
  • As of January 31, 2013 PolyMet had spent $52.7 million on environmental review and permitting, of which $46.2 million has been spent since the NorthMet Project moved from exploration to development stage.
