F.G. Cheney Limestone donates Pyrite

While recently mining in their Bellevue quarry, F.G. Cheney Limestone uncovered a unique deposit of pyrite.  This pyrite (fool’s gold) deposit was located within a piece of limestone that also contained bands of calcite.  For a couple months this impressive specimen adorned the counter of their scale house and was viewed by all that visited.  However, due its beauty and uniqueness, F.G. Cheney decided to donate this display piece to the A.E. Seaman Mineral Museum of Michigan Technological University.

The A.E. Seaman Mineral Museum is one of North America’s premier mineral museums and is nationally and internationally recognized by mineral collectors and connoisseurs. This museum features the largest public exhibit and finest collection of minerals from the Great Lakes region and the world’s best collection of Michigan minerals with currently over 4,000 samples on display and more than 40,000 samples in their total collection.  Visitors of this premier museum learn about minerals through informative displays and discover how minerals are important in your life.

F.G. Cheney’s limestone will be on display along with other pieces such as a 17-ton piece of pure native copper that was found a while dredging in Lake Superior.

If you discover a unique or interesting mineral deposit while performing your daily operations, please consider donating to a local museum or to the A.E. Seaman Mineral Museum at Michigan Tech University.
