Sugar Creek, MO: 1905 Central Plains Cement and Limestone Mine

Sugar Creek looks like a coal operation from the outside: a deep shaft, underground workings and industrial-scale output. But the material leaving this Missouri mine is limestone, the essential raw feed for cement production.

Located beside Kansas City, the operation supports Central Plains Cement’s Sugar Creek plant. The site’s roots reach back to 1905, when it opened as the Missouri Portland Cement quarry and cement works. More than a century later, mining continues beneath the community.

Access to the workings is provided through a vertical shaft descending roughly 700 feet [213m]. Underground, miners use room-and-pillar methods, cutting broad entries while leaving sections of limestone in place to support the roof. The layout includes multiple openings leading toward production and milling areas.

Scale is Sugar Creek’s defining feature. GlobalData estimated that the mine produced about 15.96 million metric tonnes of run-of-mine material in 2021, ranking it among North America’s largest underground mines by extracted tonnage. That figure represents raw limestone movement, not finished cement output.

Eagle Materials acquired the Sugar Creek cement plant and associated assets from Lafarge North America in 2012. The mine is now operated through Central Plains Cement and remains the only underground operation serving Eagle Materials’ cement network, whose other limestone sources use surface mining.

Once extracted, the rock is processed into the principal ingredient for Portland cement used across construction markets. Sugar Creek isn’t an underground coal giant. It’s something far less discussed: a century-old limestone mine operating at a scale comparable with mineral and coal operations.
