(MENAFN- Newsfile Corp) Ottawa, Ontario--(Newsfile Corp. - October 28, 2025) - NeoTerrex Minerals Inc. (TSXV: NTX) ("NeoTerrex" or the "Company") is pleased to report additional assays from its summer exploration program at its 100% owned Gravitas project (the "Project") in Abitibi-Témiscamingue, 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 4 grab samples assaying between 0.1% to 0.5% 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 5 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% and 1.23%. 8 grab samples also assayed between 0.11 g/t gold and 0.61 g/t gold ("Au"). 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% and 4.06% copper and with silver ("Ag") values of 9.09 and 13.3 g/t Ag in grab samples. Location and assays for select samples is provided in the table below.

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 (ON) and Val d'Or (QC). 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.
