CR Minerals

What CR Minerals does

CR Minerals Company, LLC is a privately held US specialty minerals producer founded in 1948 and headquartered in Southlake, Texas, with operating facilities in Ohkay Owingeh, New Mexico (pumice mining and processing, commissioned 2006) and Pueblo, Colorado (pozzolan production, commissioned 2018, expanded 2021). The company has been owned by IMin Partners, a private equity fund focused on specialty minerals and chemicals, since 1999. Its core business is the extraction, processing, and sale of high-purity pumice from the Valles Caldera volcanic deposit, marketed under the Navajo Brand, SafSil (functional fillers with sub-0.1% respirable crystalline silica), PFM (NSF-61 approved filtration media), and Mine Grade trademarks, serving paints and coatings, personal care, industrial abrasives, horticulture, and water filtration end-markets.

The company's growth engine is the Tephra product line, a portfolio of ASTM C618-certified natural pozzolans and remediated fly ash (NP, WP, RFA, and OG variants) for the concrete construction and oil and gas well cementing markets. Tephra is backed by at least six US patents covering the remediation of non-spec fly ash from coal-fired power plants into usable cementitious materials. The business sells direct to enterprise customers and through an extensive distributor network covering North America and international markets, shipping via bulk pneumatic truck, rail from the dual rail-served Pueblo facility, and oceangoing containers.

Revenue is generated through one-time product sales under quote-based pricing, with no public disclosure of pricing or contract structure. The customer base is horizontally diversified across at least seven end-use segments with no named anchor customer logos disclosed, mitigating single-customer concentration risk. CR Minerals positions its products on performance attributes (brightness, low specific gravity, particle morphology), regulatory certifications (ASTM C618, NSF-61, AWWA B100), and a sustainability narrative centered on cement carbon-footprint reduction (up to 95% versus Portland cement) and circular-economy waste fly ash remediation.
