Neoterrex Minerals samples 4.06% Cu at Gravitas

Mr. Mathieu Stephens reports NEOTERREX PROVIDES GOLD, COPPER AND TUNGSTEN ASSAY RESULTS FOR ITS GRAVITAS PROJECT, INCLUDING 4.06% COPPER Neoterrex Minerals Inc. has released additional assays from its summer exploration program at its 100-per-cent-owned Gravitas project in Abitibi-Temiscamingue in Quebec. Exploration focused on several portions of the project. On the northern block, the historical Petosa tungsten (W) zone was located and grab samples were extracted from exposed quartz veins, with four grab samples assaying between 0.1 per cent and 0.5 per cent W. Although historical trenches were located, most were filled with debris and could not manually be excavated. Further work will entail mechanical excavation of these trenches, so that the larger portion of the vein can be exposed and sampled. Tungsten was first identified in the area in the 1930s, where scheelite-bearing quartz veins, up to five metres wide and extending 150 metres in length, were exposed (Macveigh, 1954). Additional mineralized quartz veining was discovered 500 metres south of the Petosa zone. Three grab samples returned copper (Cu) values between 1.16 per cent and 1.23 per cent. Eight grab samples also assayed between 0.11 gram per tonne (g/t) gold (Au) and 0.61 g/t gold. This area located a few dozen metres from a forestry road represents a new discovery also warranting additional exploration work. Neoterrex previously reported initial results from its southern block where a north-south-trending quartz vein hosting copper-bearing sulphides of 25-metre strike length was located (Neoterrex news release dated July 17, 2025). The exploration team was able to extend the vein by 10 metres, with grab samples assaying 1.80 per cent and 4.06 per cent copper, and with silver (Ag) values of 9.09 and 13.3 g/t Ag in grab samples. Location and assays for select samples are provided in the attached table. Grab samples are selective by nature and may not represent average grades on the project. Analyses were performed by ALS Canada Ltd. with the analytical procedure performed in Sudbury, Ont., and Val d'Or, Que. 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). Assays are pending for 33 samples.

About the Gravitas project The project is in the Belleterre area, within the prolific Abitibi-Temiscamingue 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. The area is known to have several past-producing mines, including the former Belleterre gold mine between 1936 and 1959. About Neoterrex Minerals Inc. Neoterrex's projects are located in Quebec, a province recognized for its exceptional infrastructure, supportive regulatory framework and growing importance within the North American critical minerals supply chain. With a portfolio of well-positioned assets, Neoterrex is strategically aligned to capitalize on the accelerating demand for rare earth elements and other key materials essential to the defence industry and clean energy transition.
