Dear Mr. Hair,
We are writing in regard to Hudbay’s 10.9% investment in Aquila Resources’ Back Forty metallic sulfide project in Michigan’s Upper Peninsula. While Aquila has celebrated its recent receipt of the final permit for its controversial open pit sulfide mine next to the Menominee River, the mine is no closer to construction now than when the project was first discovered in 2002.
