St. Cloud Mining Company, based in Winston, New Mexico, is a mid-sized mining firm and the largest producer of natural zeolite in North America. It operates three mines and two processing facilities in the Southwest, yielding natural clinoptilolite and chabazite zeolites. The zeolites are natural, inert, and non-toxic, and are federally classified as GRAS, with applications spanning agriculture, waste management, soil conditioning, odor control, hygiene products, drying agents, desiccants, mineral fillers, wastewater treatment, radionuclide capture and air filtration. Most sales occur through private-label arrangements with distributors, brokers, manufacturers and value-added resellers, though direct sales to end users are possible based on volume. In 2025, a Bureau of Land Management decision approved exploration boreholes near the Ash Meadows Mine connected to St. Cloud's operations, indicating ongoing expansion in the region.
