Ottawa, Ontario — February 25, 2026 — Leads & Copy — NeoTerrex Minerals Inc. (TSXV: NTX) has reported additional assay results from its late fall exploration program at its 100% owned Gravitas project in Abitibi-Témiscamingue, Québec.
The company’s latest work continues to demonstrate the project’s potential for both precious and base metals, especially copper, silver and gold. The Gravitas project is located in one of Canada’s most prolific mining districts.
Following strong results earlier this season, NeoTerrex expanded its exploration footprint across previously underexplored portions of the Project, according to a company statement.
New Vein Discovery – Maxwell Block
On the centrally located Maxwell Block, approximately one kilometre from a past-producing base metals mine, NeoTerrex uncovered a previously unknown mineralized vein hosting both base and precious metals.
The vein was exposed manually over a 13-metre strike length before disappearing beneath overburden, with widths ranging from 1 metre to 30 centimetres. Despite limited bedrock exposure, the discovery highlights the strong potential for discovering new concealed mineralization near past producing deposits. A review of the historical work indicates no samples, and no drilling has ever occurred in this area.
Three grab samples were taken and were assayed for both precious and base metals which returned the following values.
Sample UTME UTMN Cu (%) Ag ppm Au ppm
L809716 655590 5248191 0.65 7.29 0.60
L809717 655590 5248191 0.10 18.35 0.71
L809718 655590 5248191 0.09 2.20 0.21
The discovery was made late in the season and follow-up could not be completed due to snow cover. The Company intends to return early in the upcoming season to undertake geophysics and trenching to determine the extent of the mineralization and its potential.
Silver Near the Petosa Tungsten Zone
Exploration around the historical Petosa Tungsten Zone revealed a broader mineralizing system than previously recognized. Newly identified outcrops located within 30 metres of the tungsten zone returned silver values ranging from 1 to 6 g/t Ag. The presence of anomalous silver in proximity to known tungsten mineralization strengthens the interpretation of a robust, multi-phase hydrothermal system and enhances the Project’s polymetallic potential.
Curie Zone – Expanding Gold-Copper-Silver System
New sampling approximately 300 metres west of the previous discovery has identified additional mineralization, with the best grab sample returning 0.28 g/t Au, 0.42% Cu and 8.15 g/t Ag.
The newly designated Curie Zone now defines an area approximately 600 metres by 200 metres containing numerous anomalous gold, copper, and silver values. The scale of the anomaly, combined with consistent multi-element enrichment, indicates a favourable geological environment capable of hosting a larger mineralized system.

Southern Block – Mineralized Vein Target
On the southern block, a 35-metre north-south trending quartz vein hosting copper-bearing sulphides was discovered early last summer. Trenching is planned as soon as ground conditions permit, with the objective of determining true width and continuity.

With multiple mineralized zones now identified across several blocks, Gravitas is demonstrating that the historical mining region still has much potential for new discoveries, said Mathieu Stephens, President and CEO of NeoTerrex.
Each phase of work continues to reveal new mineralized centres, strengthening management’s belief that Gravitas hosts a broader and more dynamic system than initially recognized. Warranting further work consisting of surface prospecting and geological mapping, mechanical trenching, in preparation for an initial drill program as none of these discoveries have been previously drilled.
Analyses were performed by ALS Canada Ltd. All samples were analyzed using the methods ME-OG46, Cu-OG46, ME-MS85 and ME-MS41. Blanks and certified reference materials (CRMs) with known grades were inserted among the samples (OREAS 622 and CDN-W-2).
The Project is in the Belleterre area, within the prolific Abitibi-Témiscamingue region. The Project is easily accessible due to a network of paved and forestry roads and benefits from the proximity of local small towns and villages.
NeoTerrex’s projects are located in Québec.
