U.S. Silica’s Pacific plant mines 98.8% whole grain silica sand from the St. Peter’s Sandstone. The physical properties of the Pacific products make it effective in flat glass, glass containers, chemical, foundry, and the oil and gas industries. The best glass in the world is made from the softest, whitest sand, or sweet sand, like that found in Pacific.

Mining operations have been conducted here since the early 1900s. Some of the initial material mined at this site was used to build the famous Route 66, which fronts the plant. In 1924, Pioneer Silica Products purchased a 205-acre tract of land and began mining underground. The underground rooms from this mine remain intact today and are used as storage and access.
