NeoTerrex Completes Phase I Exploration Program on Revolver Rare Earth
Elements Project
August 21, 2025 – Ottawa, ON, Canada – NeoTerrex Minerals Inc. (TSXV: NTX) (“NeoTerrex” or the
“Company”) is pleased to announce the successful completion of the first phase (Phase I) of its exploration
program on the 100%-owned Revolver rare earth elements (“REE”) project (the “Project”), located in the
Saguenay region of Quebec.
Highlights
• Phase I program completed: reconnaissance prospecting, detailed geological mapping, and
systematic sampling over high-priority targets.
• 21 new REE occurrences identified in 2024, with assays up to 7.16% total rare earth oxides (TREO).
• Two heavy rare earth –enriched zones prioritized for follow -up to evaluate size potential, host
geology, and extensions.
• Over 49 grab and channel samples collected from outcrops and angular boulders; assay results
currently pending analysis.
• Project advantage: located 39 km from the Niobec rare earth and niobium mine, and 35 km from
the city of Saguenay, providing excellent infrastructure access.
The Phase I program built on the strong results from the 2024 campaign, which identified 21 new REE
occurrences across the Project (see NeoTerrex December 12, 2024 news release). The 2025 work was
designed to:
• Confirm the extent and geological controls of the most promising heavy rare earth–enriched
zones.
• Expand coverage across underexplored areas of the Project.
• Collect representative samples for geochemical analysis and mineralogical studies.
Systematic sampling during Phase I resulted in the collection of more than 49 grab and channel samples,
targeting outcrops, angular boulders, and mineralized trends. These samples are now undergoing
laboratory analysis, with results expected to guide the definition of drill-ready targets.
Pending assay results from Phase I, NeoTerrex intends to:
• Conduct target definition and prioritization to select areas for mechanical stripping and trenching.
• Advance mineralogical test work to determine potential processing pathways.
• Prepare for a Phase II exploration program, which may include geophysical surveys and initial
drilling on priority targets.

Initial results highlight the Revolver Project’s potential as a new rare earth –bearing district in Quebec.
Early discoveries include light and heavy rare earths occurrences and strategically significant elements
critical to high-strength permanent magnets used in electric vehicles and military technologies.
NeoTerrex maintains a strong treasury with approximately $ 3 million in working capital and no debt,
enabling the Company to advance multiple projects in parallel. In addition to Revolver, NeoTerrex
continues to evaluate and advance its Galactic, Gravitas, and Mount Discovery projects, each of which
hosts significant rare earth element and other critical metals potential.
Through its multi-project portfolio approach, NeoTerrex aims to advance its position in the exploration of
critical metals in North America, with the objective of contributing to the long-term security of supply for
Western markets.
