What Barretts Minerals does

Barretts Minerals, rebranded in January 2025 as High Divide Minerals, is a U.S.-based talc mining and processing company that operates as High Divide Minerals, LLC from its headquarters in Dillon, Montana. The company extracts talc from multiple Montana deposits—Treasure Mine, Smith Dillon Mine, Regal Mine, and Imperial Mine—and runs processing operations in Dillon plus a manufacturing facility in Bay City, Texas, opened in 1986 to serve the U.S. Gulf Coast polyolefin market. Its product portfolio comprises ten branded lines (CT®, Sericron®, Talcron®, Microtalc®, Cercron®, Optibloc®, Polybloc®, ABT®, EcoTalc™, and Coated CT® Talc) organized by end-application across polymers, ceramics, coatings, construction, rubber, paper, and anti-block film segments. The company positions itself as the only talc supplier sourcing and processing 100% of its product in the United States, with proprietary coating technology, advanced mineral sorting equipment installed in 2019, and multiple certifications including UL 2809, UL 2908, UL Environmental Claim Validation, ISO, FDA, GMP, and USP compliance.

The business generates revenue through B2B industrial sales of talc products to manufacturers in seven primary end-markets, served via a direct sales team led by a VP of Sales and Chief Commercial Officer. Distribution is domestic-only, with operations spanning Montana mines to the Texas Gulf Coast facility. The company has implemented a temporary 1.9%–2.25% energy surcharge on orders (effective April 2026) tied to diesel pricing, indicating pass-through pricing mechanics for input cost volatility. The product portfolio spans premium brightness grades (Talcron®, Microtalc®), high-purity functional grades (Cercron®, Sericron®), recycled-content grades (CT®/Coated CT®), and value grades (EcoTalc™), giving the company price-point coverage across industrial customer tiers.

In April 2024, High Divide Minerals was acquired by Riverspan Partners as the debut investment of its inaugural fund, after which the company initiated a significant capital reinvestment cycle: a $13 million Dillon facility upgrade, a $1.5 million Bay City upgrade, a $1.55 million land purchase around Smith Dillon mine, and a $40+ million Treasure Island expansion project (partnered with Kiewit Mining Group) that extends mine life by 10+ years. The company employs between 101 and 250 people and serves North American industrial markets with no disclosed public revenue figures.
