Searching for critical minerals in Michigan | June 2019

Minerals
          Examples of Michigan critical minerals

At the Michigan Geological Survey (MGS) and the Michigan Geological Repository for Research and Education (MGRRE), we are leaving no stone unturned in our search for minerals you may never have heard of, like sylvite, cesium, and manganese. Why?

Because America depends on resources like these, defined by the Department of the Interior as the 35 鈥渃ritical minerals and rare earth elements.鈥 But we are not producing enough of them. In fact, we are not producing any of some of the 鈥渞are earth elements.鈥  We import 90% or more of these minerals and elements鈥攎ostly from .

And America鈥檚 dependence on foreign sources has increased dramatically. In the 1990鈥檚, America was the world鈥檚 top minerals producer and exporter. Now we are the world鈥檚 top importer, making us increasingly vulnerable to supply shortages and price volatility.

Our newest research grant, from the U S Geological Survey, focuses on finding these minerals in Michigan. Dr. William Harrison, MGRRE Director, is leading a research team comprised of John A. Yellich, director of the Michigan Geological Survey; Dr. Peter J. Voice, research scientist and geologist; Dr. Joyashish Thakurta, economic geologist; Jennifer L. Trout, data manager; and several graduate and undergraduate students.

In a new , Stateside discusses Michigan's role in mining these raw materials with Drs. William Harrison and Peter Voice. The interview begins at 18:40 or scroll down the NPR page for a shorter clip.
