American Rare Earths Confirms 3,497 Ppm TREO at Red Mountain

American Rare Earths reported initial certified assay results from its Red Mountain Project in Wyoming, confirming broad zones of near-surface mineralization. The company’s Chief Development Officer Andrew Conover stated that the first six of eighteen planned high-quality core holes validated the strength and continuity of the deposit. These results are a critical component of the 2026 Feasibility Study, designed to support future development decisions and enhance resource confidence.

The pooled average grade for the initial six holes was 3,497 parts per million (ppm) Total Rare Earth Oxides (TREO). This figure is significantly higher than the project’s established resource cut-off grade of 1,000 ppm TREO. The data provides additional confidence in the deposit’s size and grade distribution, aligning closely with the existing geological model and Mineral Resource Estimate.

Assay data exceeds resource cut-off

Across 386 geological assay intervals analyzed to date, the median TREO grade reached 3,879 ppm. Approximately 93% of all certified sampled intervals exceeded the company’s resource cut-off grade, indicating a consistent mineralized system. This high percentage of material above the economic threshold supports the scale and consistency of the deposit.

Drill hole HC26-RM051 delivered a maximum single-sample assay of 9,084 ppm TREO over a 3.02-metre interval. This specific interval underscores the presence of high-grade mineralization within the broader deposit. The company noted that these findings are consistent with prior geological expectations for the Cowboy State Mine.

Feasibility study drilling program progresses

The drilling program is a key element of the ongoing feasibility study. American Rare Earths has received certified assay results from six of the planned eighteen HQ core holes. The company expects additional assay data from the remaining twelve holes as laboratory processing and technical reviews continue.

The geological team is integrating the new drilling data with detailed logging and lithological interpretations. This expanded dataset will refine the understanding of the deposit and play an important role in resource classification work. According to proactiveinvestors.com, these steps are essential for advancing Red Mountain as a significant emerging rare earth development project in North America.

Future data drives economic viability

Further results will be released as assays become available and quality assurance reviews are completed. The company continues to advance Red Mountain as one of North America’s most significant emerging rare earth development projects. The integration of new data with the existing resource model is crucial for determining the project's broader economic viability.

Certified assays confirm high-grade consistency

American Rare Earths has released the first certified assay results from its 2026 Feasibility Study drilling program, providing concrete data on the mineralization at the Red Mountain Project in Wyoming. The company analyzed 386 geological intervals from the initial six HQ core holes, establishing a pooled average grade of 3,497 ppm Total Rare Earth Oxides (TREO). This figure sits well above the project’s established resource cut-off grade of 1,000 ppm.

The consistency of the deposit is highlighted by the fact that approximately 93% of the sampled intervals exceeded that 1,000 ppm threshold. These results align closely with the existing geological model and Mineral Resource Estimate for the Cowboy State Mine, reinforcing the continuity of near-surface mineralization across the drilled area.
