A Legacy of Purity, A Vision for the Future

Deep in the geothermal, mineral-rich foothills of Clark County, Idaho, lies a landscape still largely untouched — a place where purity hasn’t been engineered, but unearthed.

Since 1962, these lands have been selectively mined by a handful of operators, each drawn to the rare calcium-rich deposits beneath the surface. In the 1990s, Thermocal Minerals of Idaho become part of the Van Beek Group of companies. Van Beek Natural Science purchased the site to include the unrivalled mineral deposit into their animal health and agricultural products.

Thermocal Minerals of Idaho (TMI) is now a trusted name in the industry. As the mineral market evolves — with rising demand for year-round supply and sustainability — a new chapter begins. TMI continues its legacy under a new banner: Idavue Minerals.

And with it, a bold commitment to scale, serve, and steward the land.
