Mankato-Kasota Stone ceases operations after four generations


Mankato-Kasota Stone, which has provided Minnesota limestone for projects around the world, has ceased operations. Founded in 1885, Kasota Stone is one of Mankato's oldest businesses.

The Mankato Free Press confirmed the closing with an official with Coughlan Cos. Inc., the holding company that owns the company.

"This has been very difficult," said Robert Coughlan of Mankato-Kasota Stone, who blamed slowdown in construction for the decreased demand for limestone. "I'm the fourth generation of our family to do this."

The Star Tribune reports that Mankato-Kasota Stone can be found on numerous public buildings and private homes, from the Nokomis Library in Minneapolis to many University of St. Thomas buildings. The Mankato Kasota Stone quarries are situated in Mankato.

More than two dozen employees have been either laid off or have found work with another Coughlan family business, Capstone Press

Coughlan said he hopes to recall some employees when the family begins operating its Jordan Sands silica sand project, perhaps by next spring. The operation will mine silica sand from quarries in Mankato and neighboring Lime Township. Silica sand is used in "fracking" to extract natural gas.
