3. History
The last operating non-ferrous metallic mine in Michigan (White Pine Mine) closed in the mid 1990’s
In early 2002 Michigan began to experience a resurgence in mineral exploration in the UP
In early 2004 DEQ formed a stakeholder group
In December, 2004 Legislation was passed that will ensure the economic development potential of mining in our state, while being mindful of protecting our environment

7. Summary Three active mines; Two potential mines
Not a mining rush, more like a “Cautious Resurgence”
Significant exploration activities compared to the 1980’s and 1990’s
Metal prices and companies’ ability to attract investors will dictate the future for pending projects
