ST. PAUL, MINNESOTA--(Marketwired - Oct 8, 2014) - PolyMet Mining Corp. ("PolyMet" or the "Company") (POM.TO)(NYSE MKT:PLM) - is pleased to report that the Minnesota Department of Natural Resources is working toward an "early spring" 2015 completion of the final Environmental Impact Statement for the Company's NorthMet project.

"My goal is to have the EIS out the door early next spring," DNR Commissioner Tom Landwehr told about 80 elected officials representing cities and towns across Minnesota's Iron Range who gathered this week for a mining forum in Virginia, Minn. The forum was sponsored by the Range Association of Municipalities and Schools.

Commissioner Landwehr, Pollution Control Agency Commissioner John Linc Stine and Iron Range Resources and Rehabilitation Board Commissioner Tony Sertich also addressed the forum. The commissioners emphasized that getting the final EIS right will help the subsequent permitting process run more smoothly.

Commisioner Landwehr said getting to the final EIS "will require that a lot of things fall into place," adding that the DNR will continue its coordination with the co-lead agencies and its sister state agencies to produce the final EIS. DNR will be "looking for any efficiencies between the agency and the company…to cut that time as short as possible," he said.

PolyMet must obtain a number of state and federal permits, including air and water discharge permits from the state Pollution Control Agency prior to construction. PCA Commissioner Stine said his agency aims to come to a decision on those permits within 150 days of application in accordance with state law.

"We appreciate the tremendous amount of work and resources the agencies are devoting to ensure the final EIS is thorough and responds appropriately to the public comments on the draft EIS. There is an enormous amount of hard work going into this critically important final phase of the environmental review," said Jon Cherry, PolyMet president and CEO.

"The commissioners' stated goals give us optimism the EIS can be finalized by early spring and we can have permits in place during the 2015 construction season in northern Minnesota," Cherry said. The project will generate about two million construction hours over a 15-month period, while the long-term benefits include creation of more than 900 direct and indirect jobs and $515 million annually in economic benefit to the region.
