NeoTerrex Expands Copper-Gold-Silver

Discoveries at Gravitas

Ottawa, Ontario--(Newsfile Corp. - February 25, 2026) - NeoTerrex Minerals Inc. (TSXV: NTX)

("NeoTerrex" or the "Company") is pleased to report additional assay results from its late fall exploration

program at its 100% owned Gravitas project (the "Project") in Abitibi-Témiscamingue, Québec, one of

Canada's most prolific mining districts.

Following strong results earlier this season (see NeoTerrex news release dated October 28, 2025),

NeoTerrex expanded its exploration footprint across previously underexplored portions of the Project.

The latest work continues to demonstrate the Project's potential for both precious and base metals,

especially copper ("Cu"), silver ("Ag") and gold ("Au").

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.

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.

Building Momentum at Gravitas

Mathieu Stephens, President and CEO of NeoTerrex commented: "With multiple mineralized zones now

identified across several blocks, Gravitas is demonstrating that the historical mining region still has much

potential for new discoveries. What began as a tungsten-focused project is now clearly evolving into a

diversified gold-copper-silver-tungsten project with numerous discoveries to develop."

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.

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).
