Highlights

• GLO-owned ranch in Brewster County confirmed to have rare earth mineral anomalies in early discovery phase.
• No active mining or exploration currently underway due to rugged terrain and high extraction costs.
• U.S. Geological Survey has collected initial radiometric and magnetic data.
• Further analysis needed to determine economic viability.

A 353,000-acre ranch in Brewster County, Texas, owned by the state’s General Land Office (GLO), has been confirmed to contain rare earth mineral anomalies, according to a recent report by The Big Bend Sentinel. While the finding aligns with national efforts to map domestic critical minerals, retail investors should note that this project remains in an early discovery phase.

A geological survey has identified the presence of rare earth minerals, but no active exploration or mining has commenced. GLO has not released data on the specific rare earth elements found, nor has it confirmed economic concentrations. Officials cite the rugged terrain, remoteness, and high costs of extraction as major hurdles to near-term development. Current land use includes ranching and hunting leases, with ecotourism also under consideration.

While the region sits on the promising alkaline igneous belt—home to other prospective deposits like Round Top—no pre-feasibility study, resource estimate, or permitting activity has yet been disclosed for Brewster. Earth MRI, the U.S. Geological Survey’s mapping initiative, has collected radiometric and magnetic data over the area, but further on-site analysis is needed to determine if these anomalies translate into mineable resources.

In short: Brewster County’s rare earths are on the map, but far from market. The land holds promise—but not yet a project pipeline. See the Big Bend Sentinel. (opens in a new tab)
