In 1874 General George Armstrong Custer led an expedition into the Black Hills of Dakota Territory. Camping along a small stream, now called French Creek, General Custer and the men of the 7th Cavalry discovered gold. Founded on this sight, the town of Custer, South Dakota began. The first feldspar milling operation began business in 1928. For more than 80 years, high quality potash feldspar has been produced from the rich pegmatite ore deposits of the Black Hills mines.
In 1970, Pacer Corporation acquired the original feldspar mining operations and today continues the tradition of producing high quality Potash Feldspar. Our Custer Feldspar or “Custer Spar” is a recognized name throughout the ceramic, sanitary whiteware, coatings and related industrial mineral industries.
In 1978, Pacer discovered and claimed it’s premier muscovite mica mineral deposits , a vast reserve of mica ore with unique flowability and reinforcement characteristics used to produce our high quality DakotaPURETM mica.
In 2005, Pacer opened a new mica processing facility that doubled existing production capacity that allowed the company to expand into the oil well drilling markets through its mica-based loss circulation material (LCM). Additionally, the company installed milling, screening and jet mill finishing equipment that allowed Pacer to expand into the industrial minerals fillers and compounding markets that included powder coatings, abrasives, adhesives, sealants, cementitious products, joint compound, and plastics.
In 2016, Pacer Corporation changed ownership and management. Under a new name and business philosophy, Pacer Minerals, LLC has improved mining practices, modernized ore sorting techniques, restructured quality control procedures and most importantly, hold our customers in the highest regard. With these changes the company has reinvigorated past customer relationships, secured new customers and formed new business-to-business (B2B) linkages.
