Dear Mr. Roosen,
We are writing in regard to Osisko’s 15% ownership of Aquila Resources’ Back Forty metallic sulfide deposit in Michigan’s Upper Peninsula. Aquila has promoted the idea that this project is a done deal. However, recent events should give your shareholders cause for concern. The Michigan Department of Environmental Quality’s (DEQ) public hearing on Aquila’s wetland permit demonstrated serious technical problems with the permit application as well as continuing widespread public opposition to this controversial project.
