PolyMet Mining Corp. (NYSE MKT:PLM) said Thursday it’s making progress in the environmental review process for its proposed copper-nickel-precious metals mining project.

Company executives say PolyMet has undertaken an extensive review of all aspects of its NorthMet project and proposed improvements that will reduce environmental impacts, including:

• Reductions in sulfur dioxide, mercury and greenhouse gas emissions at the plant site.

• Capture of groundwater and surface seepage with the construction of an in-ground containment system to the north and west of the existing tailings basin.

• All contact water discharged from the project will be treated through reverse osmosis plants. A pilot treatment plant has successfully treated more than 1.5 million gallons of and meets applicable state and federal water quality standards, including those that protect Minnesota's wild rice standard for sulfate.

“Reductions in the environmental impact of our project are a significant step toward completion of the supplemental draft EIS, which is on track for mid-summer 2013,” said Jon Cherry, PolyMet's president and CEO. “We are now commencing detailed capital and operating cost updates based on these project changes and are reviewing detailed construction plans and schedules to prepare for project construction once we receive permits."
