NeoTerrex Minerals Reports Commencement of Drilling at the Monument Project and the Discovery of 44 New Occurrences at the Galactic Project

Highlights:

• 2,000 metre drill program underway at the Monument project

• Drilling targets geophysical anomalies prospective for rare earths and sulphide mineralization (Monument project)

• 44 new occurrences discovered at Galactic project (82 since 2024) (Galactic project)

• Galactic Zirconium ("Zr") assay results among highest recorded in the province in grab samples (17.15% Zr) (Galactic project)

• Numerous Tantalum ("Ta"), Dysprosium ("Dy"), Neodymium ("Nd") and Niobium ("Nb") occurrences discovered at Galactic, including 2.44% Nd (Galactic project)

Monument Project Drilling

NeoTerrex has initiated a 2,000-metre drill program at its Monument project, situated in the Waswanipi/Montviel region of Québec. The program is testing high-priority geophysical targets identified during recent surveys that outlined strong electromagnetic anomalies coincident with highly magnetic bedrock. These signatures are comparable to those associated with the nearby Montviel light rare earth deposit, which hosts a National Instrument 43-101 compliant indicated resource of 183.9 million tonnes grading 1.45% TREO and an inferred resource of 66.7 million tonnes grading 1.46% TREO (SGS Canada, 2011).

The current phase will include approximately 14 holes, with the potential for expansion based on early results. Only two historical holes, drilled in the 1990s in search of kimberlites, are known within the project boundaries; both intersected carbonatites, a key host rock for rare earth mineralization, but were never assayed for rare earths.

Galactic Project Discoveries

At the Galactic project, NeoTerrex completed a spring exploration program consisting of prospecting, mapping, and channel sampling. A total of 44 new mineralized occurrences were discovered, extending known mineralized zones and confirming the district-scale critical-metal potential of the project. The program also included channel sampling in locations where bedrock exposure was more prevalent. A table of the 2025 results and their coordinates is provided further below, adding to the 38 occurrences located last year (NeoTerrex December 6, 2024 news release). A map indicating the location of discoveries in relation to last year's results is also provided.

Among the new discoveries, the Supernova showing, located 650 metres north of the 2024 Hubble occurrence, returned grab samples grading 17.15% and 5.61% Zr, along with elevated Nd, Nb, and Ta values. Channel sampling, including at Supernova has been completed. These assays are pending.

Additional high-grade zirconium results include 12.95% Zr from the Nebula area (1.2 kilometres northeast of 2024 discoveries) and 10.05% Zr from the newly discovered Aries showing. Sampling near the Ceres showing yielded 2.44% Nd, 0.77% Nb, 0.10% Dy, and 8.18% Zr, while a nearby outcrop returned 1.31% Nb, 4.55% Zr, and 0.13% Dy. Zirconium is considered a critical metal due to its importance in a wide range of technologies, including aerospace, defense, and nuclear energy.

Results also indicate that some mineralized areas have a larger footprint than previously thought. In the Andromeda sector, additional mineralized outcrops were located to the west and north, indicating that mineralization is present over an area of approximately 200 metres by 100 metres. Additional discoveries were also made 100 metres south in an area measuring 70 metres by 80 metres. Several new occurrences were also discovered in an area not explored in 2024. These include the Phoenix occurrence yielding 0.36% Dy and 936 ppm Ta.

QA/QC

Grab samples are selective by nature and may not represent average grades on this project. Analyses were performed by ALS Canada Ltd. with the analytical procedure performed in Vancouver (BC). Samples were analyzed using the methods ME-OGREE, ME-XRF15c, ME-MS71L and ME-MS81h. Blanks and certified reference materials (CRMs) with known grades were inserted among the samples (OREAS 463).

Mathieu Stephens, NeoTerrex's President and CEO commented: "The 2025 results have exceeded our expectations for a two-week exploration program. NeoTerrex is fortunate to advance a project hosting such a wide spectrum of critical metals, all within an accessible and geologically diverse setting. We are now integrating these results into an updated geological model in preparation for the next phase of work, which will include mechanical trenching and drilling.

The Galactic project continues to deliver discoveries across multiple critical metals, while the commencement of drilling at Monument represents a major milestone for the Company. Few projects combine this level of geological diversity, metal potential, and ease of access, and we're eager to advance both projects to the next stage of exploration."
