U.S. Silica's Dubberly plant produces fine grain silica from a mineral resource known as the "Sparta" Formation. The Sparta consists primarily of loose, unconsolidated, fine to coarse, light-colored sand intermingled with light-colored clays, which is processed for the glass, chemical, roofing, brick and foundry industries.
Dresser Industries carried out an extensive exploration program during the summer of 1970, which resulted in the discovery of the South Dubberly deposit. They broke ground on the plant in 1971 and delivered their first shipment of glass sand in December 1972. Dresser Industries operated the facility until it was purchased by Ottawa Silica Company in July 1981, which merged into the U.S. Silica family in 1987.
The Dubberly employees strive to be exemplary members of their community and to preserve the environment in which they operate. Their efforts include land reclamation and recycling process water. Additionally, employees of Dubberly volunteer through local fire departments, youth activities and local service organizations.
