Minnesota: Copper Mining Tailings Ponds are not Healthy for Children and Other Living Things (and Neither are Hydrofluoric Acid Storage Tanks)

An Open Letter to the Affected Mayors, City Councilors and Assorted Thought Leaders who Inhabit the Areas Downstream and Downwind

The first (of many) junior mining companies that want to mine copper in northeast Minnesota’s water-rich, relatively unspoiled forest and lakes region is the PolyMet Mining Corporation that is headquartered in Toronto, Canada.

PolyMet is a Canadian Penny Stock mining company that you can buy on the NYSE for 81 cents a share. It’s peak share price over the past 12 months was $1.36 a share, but it isn’t on anybody “buy” list at the moment.

PolyMet has never mined anything in its life and has never earned a single penny producing anything of value. It is a front group for Glencore, a multinational mining, commodities and oil and gas trading company that is based in Switzerland. Both corporations prefer doing business hidden behind boardroom walls. PolyMet’s daily operations are mostly funded by greedy institutional investors and loans from the deep-pocketed Glencore. Neither corporation should have any credibility in the minds of right-thinking individuals. I will explain that statement later in the column.

In January 2011, Glencore and PolyMet, signed a secret agreement that guaranteed that Glencore could buy controlling interest in PolyMet with the right to convert it’s debt into equity. It is public knowledge that Glencore also has the rights to sell all the metal that is mined in the first 5 years of production in the world’s markets.

Contrary to PolyMet’s talking points about being good citizens by producing copper for all of our needs, none of the copper that is mined by PolyMet might ever be utilized here at home. More

Duty to Warn

Requesting honest information from the Minnesota DNR, the Minnesota PCA and the US Forest Service regarding the latest PolyMet project permit application:

Please respond to the concerned folks to which this email has been cc’ed, all the details of the permit that the foreign corporation Glencore has submitted to the MNDNR, MNPCA, or US Forest Service concerning the establishment and maintainance of their enormously dangerous, potentially catastrophic, toxic tailings lagoon, an entity that seems to have been conveniently ignored by the media cheerleaders and even you regulatory entities.

I don’t recall seeing any permit application published for the eventual 250 foot high earthen dams that will hold back for eternity the tens of millions of cubic meters of poisonous liquid sludge that the copper/nickel/sulfuric acid mine will inevitably produce (and need to be stored).

Anybody with any awareness of the risks of the toxic metal and sulfuric acid recognizes that the tailings lagoon MUST be the center of discussion. So far it is rarely mentioned in the occasional news bulletins.

Every copper/nickel liquid tailings pond holds the 99.8% mine waste plus the liquids that is used to pipe the dissolved powder from the processing plant to the pond.

Every copper/nickel sulfide mine in the history of mining has leaked/leached poisons into the groundwater, onto adjacent lands and into the downstream environment. This happens at all copper mine sites that are located in watery environments such as northern Minnesota. More
