PolyMet Mining Corp. is offering Minnesota a $544 million package of financial assurances to serve as an insurance policy to protect taxpayers from having to cover the costs of shutting down and cleaning up the copper-nickel mine it proposes to build in northeastern Minnesota.

The company said in an updated permit application Wednesday that the package of bonds, letters of credit and a trust fund will be sufficient to cover all the costs, including treating the mine's wastewater for as long as necessary.

Environmental groups say copper-nickel mines elsewhere have a long track record of going bankrupt and leaving taxpayers stuck with the cleanup costs.
