About Us

EP Minerals, formerly EaglePicher Minerals, is a specialty minerals producer headquartered in Reno, Nevada. We have been mining diatomaceous earth (DE) since 1945. With a strong focus on Quality, Innovation, and Customer Service, EP Minerals is the second-largest producer of DE in the world and the largest in North America. Since the current management team arrived in 2004, revenues have increased by over 100% through organic growth in our core products.

Since 2011, EP Minerals has been privately-owned by Golden Gate Capital, and with their support we are entering a period of significant strategic investment and growth -- increasing our portfolio of minerals to better serve our core markets and developing new and exciting applications for our core products.
