History and Vision

Coming Together: Past, Present and Future

In the late 1800s, pioneer Henry Harrison Hunter mined and processed his first sand sample by hand near Berkeley Springs, West Virginia. Hunter entered this sand sample in the Chicago World's Fair. He won a blue ribbon and the medal of excellence for the sand's purity. A small plant was built to mine the deposit to produce silica sand for glass manufacturing. Just a short distance away, Lewistown, Pennsylvania resident Samuel S. Woods incorporated another silica sand production plant. That plant would eventually become the Pennsylvania Glass Sand Corporation.

Over the next 50 years, numerous silica sand mining companies started up across the country. They were subsequently acquired and merged – by leaders looking to capitalize on both the natural resources being discovered and the human expertise that was taking shape.

The rise of the industry reflects U.S. Silica’s own path. The company as it exists today has undergone many developments over the years, including the merging of the Pennsylvania Glass Sand Corporation and Ottawa Silica Company to form what is now known as U.S. Silica Company. Today, we have over 15 locations across the country. We upgrade our facilities and equipment regularly, and invest in our employees to ensure that our knowledge base remains state-of-the-art.

Our standards are high. We strive to increase and improve functionality on an ongoing basis. To provide the safest, most cost-efficient operations. To produce and transport high-quality minerals to customers around the world.  To continue to innovate – for and with our customers, employees, and communities.

Above all, we strive to continue our role as a leader in industrial minerals innovation, embracing future challenges and opportunities.
