ION Minerals, a private holder of brine-borne lithium interests in North America, has expanded its diversified lithium resource portfolio to more than 280,000 mineral acres across East Texas, the Texas Panhandle, and Southeast Saskatchewan. The company achieved this growth through targeted acquisitions, leasing and geological evaluation aimed at strengthening its position as a lithium developer supporting the North American battery supply chain.
East Texas
In East Texas, ION Minerals controls nearly 50,000 mineral acres in the Smackover Formation, situated near other major brine projects in Southwest Arkansas and East Texas. Published data report resource densities of 47–60 tonnes of lithium carbonate equivalent per acre, positioning this acreage within a key brine development corridor with established production history.
Texas Panhandle
In the Texas Panhandle, the company holds almost 65,000 mineral acres in the Brown and White Dolomite Formations. Internal analysis using public and proprietary data suggests this region may host up to 2.4 million tonnes of lithium carbonate equivalent. The acreage lies within a broader area of interest spanning nearly 500,000 acres and offers potential for commercial-scale development.
Southeast Saskatchewan
In Southeast Saskatchewan, ION recently acquired just over 165,000 mineral acres targeting the Duperow Formation. Preliminary geological data and independent analogs estimate this acreage could contain as much as 2.5 million tonnes of lithium carbonate equivalent across multiple productive benches. Drilling and testing are scheduled to start in summer 2026.
With these expansions, ION Minerals aims to deliver responsibly sourced lithium critical for electric vehicles, grid storage and other electrification initiatives. The company’s 280,000-acre land position in jurisdictions focused on domestic supply chain security aligns with policy objectives in both the United States and Canada.
