Public Comment Period Extended for Eagle East

“Never doubt that a small group of thoughtful, committed citizens can change the world; indeed, it’s the only thing that ever has.”  – Margaret Mead


ACTION ALERT! Tell the Michigan Department of Environmental Quality exactly what you think of Lundin Mining’s requested amendment of the Eagle Mine permit — which would require building more than 8 KILOMETERS of NEW tunnels to reach a totally DIFFERENT orebody, called “Eagle East.”

Eagle East is a new orebody located beyond the previously permitted project boundary for the Eagle Mine. This major expansion could have serious environmental impacts that were never considered under the original permit. More mining will mean more tailings, more dewatering, and increased risk of contamination. Read the proposed Eagle East permit amendment for yourself!


1.) Lundin Mining claims the life of Eagle Mine will be extended only 1 or 2 years by extracting the Eagle East deposit. Is it worth the environmental impact to the beloved Yellow Dog Plains, or the Salmon Trout, Yellow Dog and Escanaba Rivers? Eagle East will result in increased hauling, air pollution emissions, tailings waste problems for Humboldt Mill,  and increased discharge of pollutants to the Middle Branch of the Escanaba River.

2.) Lundin describes the combined ore as “Eagle ore” but Eagle and Eagle East are different orebodies, born from different volcanogenic sources. The new Eagle East orebody contains higher grades of copper and nickel, as well as other toxic heavy metals. These metals can be extremely dangerous for aquatic life, headwater streams, and wetlands. Were these threats taken into account in the initial environmental impact assessment, or does this represent a significant change from the original permit?

3.) The Eagle East orebody is located three thousand feet below the surface, much deeper than Eagle, so the ore contains high quantities of entrapped salts from ancient brines. These salts will create long term problems for Lundin’s Humboldt Pit, where the addition of Eagle East tailings are expected to nearly fill the pit with waste, dramatically increasing Total Dissolved Solids. Eagle’s wastewater treatment plant will also need a new crystallizer.

4.) Mining experts have repeatedly warned that the Eagle orebody is filled with hard-to-map “smaller-scale discontinuities that could weaken the rock mass.” Last year’s undisclosed underground “collapse” at Eagle Mine throws the overall safety of the mine’s expansion into question. Has Eagle Mine’s stability been dangerously overestimated from the beginning? Are you concerned about last year’s rock failure at Eagle Mine?

Please let the DEQ know that you want ALL of these serious questions thoroughly reviewed and resolved, before the Eagle Mine permit amendment is considered.

The DEQ has extended the public comment period to July 20th, instead of the previous July 6th deadline. Following the federal holiday for the 4th of July, we will share more details about Eagle East and the environmental impacts, citing specific concerns.

SUBMIT WRITTEN COMMENTS! Public comment on the proposed permit amendment will be accepted until 5 PM on Thursday, July 20th, 2017.
