century of mining and processing experience in industrial minerals,
becoming the established standard of excellence in the production

combined the marketing and production strength of two of North
America's top silica companies. This leadership in the
industrial minerals field is complemented by a deep commitment to
providing quality products and exceptional service to our
customers. This will be
accomplished through a commitment to quality, health and
