NEW YORK PolyMet Mining Corp. has treated more than 1 million gallons of water at its new pilot water treatment plant since May as it looks to demonstrate its adherence to strict environmental standards in an effort to secure permits for its proposed copper-nickel-precious metals mine.
The Hoyt Lakes, Minn.-based junior miner, which has been working to bring its NorthMet Mine and related processing facility in northeastern Minnesota online for years, said it hopes to eventually expand its pilot technology into a full-scale treatment plant.
"We want both the community and agencies to understand our commitment to constructing and operating (the) NorthMet Project in an environmentally responsible manner that meets all applicable standards," PolyMet president and chief executive officer Jon Cherry said in a statement.
