Company looks forward to presenting scientific evidence showing no downstream water quality effects
The Environmental Protection Agency today concluded that PolyMet's proposed copper-nickel-precious metals mining project "may affect" waters on the Fond du Lac reservation and in the State of Wisconsin, both of which are located well over 100 river miles downstream, according to Poly Met Mining, Inc., a wholly owned subsidiary of PolyMet Mining Corp. (TSX: POM) (NYSE American: PLM) (together "PolyMet" or the "company") .
EPA's decision does not say PolyMet's project will affect downstream water quality, only that such an effect is possible. The Minnesota Pollution Control Agency (MPCA) certified in 2018 that the project would not affect in-state water quality under section 401 of the Clean Water Act. PolyMet now will present the evidence on which the MPCA relied to the Army Corps of Engineers, which will likely require a hearing to make a final decision on the project's downstream water quality effects.
When in operation, PolyMet's project will collect and treat water, including water that holds mercury and other contaminants from historical taconite mining, resulting in a net reduction of contaminants to the St. Louis River system. "I am hard pressed to understand how our treated water can meet water quality standards at the point of discharge and at other downstream communities closer to the project site, and actually reduce overall mercury loading to the river, but somehow 'may affect' water in places located more than 100 river miles downstream," said Jon Cherry, chairman, president and CEO.
"We disagree with the EPA's new conclusion since the science is clear that water discharges from the NorthMet mine will not only meet water quality standards, but are proven to have a net benefit to the St. Louis River's water quality," Cherry said.
Because EPA's downstream water quality determination is a prerequisite for the section 404 wetlands permit issued to PolyMet by the Corps of Engineers, the Corps placed the permit on hold during EPA's review. That hold is expected to remain in place during any Corps hearing.
PolyMet will work with the EPA and Corps to address this issue. If necessary, it will again demonstrate that its project will cause a net reduction of mercury loading to the St. Louis River.

About PolyMet
PolyMet is a mine development company that owns 100% of the NorthMet Project, the first large-scale project to be permitted within the Duluth Complex in northeastern Minnesota, one of the world's major, undeveloped mining regions. NorthMet has significant proven and probable reserves of copper, nickel and palladium - metals vital to global carbon reduction efforts - in addition to marketable reserves of cobalt, platinum and gold. When operational, NorthMet will become one of the leading producers of nickel, palladium and cobalt in the U.S., providing a much needed, responsibly mined source of these critical and essential metals.
Located in the Mesabi Iron Range, the project will provide economic diversity while leveraging the region's established supplier network and skilled workforce, and generate a level of activity that will have a significant effect in the local economy. For more information: www.polymetmining.com.
