125 Year Tradition

Comments Off on 125 Year Tradition

In 1885, T. R. Coughlan first began quarrying the Oneota Dolomite Formation in the Mankato area. Since then, the Coughlan family has continued to promote the region’s rich mining heritage adjacent to the Minnesota River Valley.

Jordan Sands was formed in 2011 to responsibly develop the Jordan Sandstone resource underlying the Coughlan Companies’ land holdings, for emerging opportunities in the oil & gas fracturing (frac) sand market. The favorable existing land position is comprised of both surface and mineral rights.


Jordan Sands LLC, is an industrial sand mining and processing operation and an affiliate of Coughlan Companies, Inc., Mankato, MN, whose primary business includes a children’s book publishing company Capstone.
