Our operations include best-in-class mines and production facilities in Clinton, Wisconsin and New Auburn, Wisconsin as well as San Antonio, Texas.

Our state-of-the-art facility in Clinton is located directly on the Canadian National railroad for ease of transportation to markets to the East and West. With private track that holds 450 cars, and a throughput capacity of 2.4 mm tpy of high-quality Northern white sand, this facility allows for high-volume unit train or manifest shipments to the customers’ specific locations. Our all-weather, enclosed facility, fed by three high-output mines, offers assurance in feed and on-time shipments, regardless of weather conditions, by our experienced quality assurance and operations teams.

Our New Auburn plant is conveniently located directly on the Progressive Rail Short Line that connects to the Union Pacific Railroad, giving us full control of coordinating, loading and shipping railcars to any destination in the U.S., particularly to the South. We have four 4,000-foot storage tracks on our property with the ability to hold up to 425 railcars, optimizing car availability for our customers’ order fulfillment. Like the Clinton facility, the plant is a fully enclosed, all-weather facility, which enables Superior Silica Sands to produce frac sand at full capacity in the worst of winter weather.

The uniqueness of our Texas and Wisconsin sands provide superior brightness and consistency for color-sensitive applications. The roundness of our Wisconsin sands and the sub-angularity of our Texas sands allows us to customize products for a diversity of markets. Product consistency, quality, and reliability of supply give us a considerable competitive advantage in the markets we serve – and that means direct benefits for our customers.
