About Pacer

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 watched the first feldspar milling operation begin business in 1928. For more than 75 years, high quality potash feldspar has been produced from the rich pegmatite ore deposits of the Black Hills mines with historically colorful names such as the White Elephant, the Pink Monster and the Bull Moose to name a few.

In 1970, Pacer Corporation acquired the original feldspar mining operations and today continues the tradition of producing high quality potash feldspar.

In 1978, Pacer discovered and claimed the muscovite mica deposits, a vast reserve of mica ore with unique flowability and reinforcement characteristics used to produce our high quality DakotaPURE mica.

In October 2005, Pacer opened a state-of-the-art mica processing facility which more than doubled our production capacity. As our global customer base continues to grow and discover the unique characteristics of our mica, Pacer has the processing capacity and mica ore reserves to continue our expansion.

Our comitment to innovation and technology, together with a statistical process quality control program, insure consistent product chemistry and sieves while giving us the versatility to engineer and produce products to meet our customers’ specific needs.
