NeoTerrex Assays 12.87% TREO at Its Revolver Project, Including 2.1% Neodymium Oxide
None
On October 24, 2025, NeoTerrex Minerals announced high-grade assay results from reconnaissance work at its Revolver Rare Earth Elements (REE) project in Quebec. The highlight was a grab sample that returned 12.87% Total Rare Earth Oxides (TREO). This sample also contained significant concentrations of high-value magnet metals, including 2.1% Neodymium Oxide and 0.44% Dysprosium Oxide.
The company noted that this grade ranks among the highest reported in Quebec government databases. The mineralization is hosted in monazite, a mineral known for favorable metallurgical characteristics for REE extraction. Following these results, NeoTerrex has initiated mineralogical and metallurgical test work and is planning a follow-up program that will include geophysical surveys, mechanical stripping, trenching, and an initial drill program.
This news is materially positive as it significantly increases the prospectivity of the Revolver project. The reported 12.87% TREO is a substantial improvement over the previous high of 7.16% TREO announced in December 2024. The confirmation of valuable magnet metals (Neodymium and Dysprosium) and favorable host mineralogy (monazite) adds significant technical merit to the discovery.
However, a critical perspective is required. The results are from a single grab sample. The company's own disclaimer notes that "Grab samples are selective by nature and may not represent the true metal content of the mineralized zone." While this result is an excellent vector for future exploration and justifies the planned drilling, it does not confirm the existence of an economic deposit. The market for junior explorers is often driven by high-grade "headline" numbers, but the true test will be drilling to determine the width, grade continuity, and scale of this mineralization.
Looking at the project's progression: - Dec 12, 2024: NeoTerrex first announced results from Revolver, with 78 grab samples returning up to 7.16% TREO. - Aug 21, 2025: The company completed a Phase I program of mapping and sampling, with over 49 samples sent for analysis. Today's news reports on these results.
The current news confirms the company's exploration thesis at Revolver is sound and has yielded better-than-expected surface results. It provides a clear, high-priority target for the company's first drill program on the property. While not a "game-changer" until backed by drill intercepts, it is a significant and positive step in advancing the project.
NeoTerrex Minerals is a junior exploration company focused on critical and strategic minerals within the mining-friendly jurisdiction of Quebec, Canada. The company holds a portfolio of early-stage projects prospective for Rare Earth Elements (REEs), tungsten, copper, and gold.
While the company is advancing multiple projects, the primary focus appears to be on its REE portfolio. The Revolver Project is now a key asset following the discovery of very high-grade surface mineralization containing valuable magnet metals. Concurrently, the Monument REE Project, located near a known large REE deposit, is drill-ready with a maiden program planned for November 2025.
