ATEX Intersects 20 Meters of 4.10% CuEq Within 78 Meters of 3.03% CuEq at the Southern Boundary of the High-Grade B2B Breccia

35% of Assays Remain Pending for Phase VI Program

Toronto, Ontario--(Newsfile Corp. - July 8, 2026) - ATEX Resources Inc. (TSX: ATX) (OTCQX: ATXRF) ("ATEX" or the "Company") is pleased to announce additional drill results from the Valeriano Copper-Gold Project ("Valeriano" or the "Project") in the Atacama region of Chile, including complete results from holes ATXD23C, ATXD31A, and partial results from hole ATXD31B. Phase VI drilling totaled a record of approximately 28,400 meters ("m"), exceeding the initial 25,000m program target. Approximately 65% of assays have now been released for the Phase VI drill program with remaining results expected through July.

Chris Beer, Interim President and CEO commented, "These results continue to strengthen our confidence in the continuity of the high-grade B2B breccia and its relationship to the underlying high-grade porphyry system. Hole ATXD23C adds significant high-grade mineralization at the southern boundary of the currently defined B2B Mineral Resource, while holes ATXD31A and ATXD31B demonstrate that the system remains open to the north. Previously reported results from hole ATXD19A indicate that the B2B breccia extends approximately 180m to the south where follow-up drilling will resume in September with the continuation of hole ATXD19B as part of our Phase VII program.

Collectively, these results improve our understanding of the geometry, continuity and scale of the B2B breccia while reinforcing our interpretation that the highest-grade mineralization forms part of a much larger porphyry system with significant growth potential. Based on drilling completed to date, the B2B breccia has now been traced over approximately 600m representing a 50% increase from the previously interpreted 400m strike length. With several holes ending in mineralization and approximately 35% of Phase VI assays still pending, we believe there remains substantial opportunity to continue expanding both the high-grade B2B breccia and the broader Valeriano mineralized system."

Highlights:

• ATXD23C intersected 20m of 4.10% CuEq (2.53% Cu, 1.39 g/t Au, 9.3 g/t Ag, 84.0 g/t Mo), within broader intervals of 78m of 3.03% CuEq (1.91% Cu, 0.99 g/t Au, 6.6 g/t Ag, 107.2 g/t Mo) and 124m of 2.65% CuEq (1.67% Cu, 0.86 g/t Au, 5.5 g/t Ag, 102.4 g/t Mo), representing some of the highest-grade intervals drilled at Valeriano.

  • Further defined the geometry of the high-grade B2B breccia, increasing confidence in its interpreted size, shape and volume.

  • Confirmed continuity between the high-grade B2B breccia and the underlying high-grade porphyry, reinforcing the interpretation of a larger, connected mineralized porphyry system.

  • Hole ended in mineralized porphyry, highlighting the potential to further expand both the high-grade B2B core and the underlying high-grade porphyry core.

• ATXD31A intersected 64m of 1.02% CuEq (0.52% Cu, 0.45 g/t Au, 2.3 g/t Ag, 3.5 g/t Mo) and including a broader interval of 84m of 0.96% CuEq (0.62% Cu, 0.30 g/t Au, 1.7 g/t Ag, 12.4 g/t Mo), confirming high-grade mineralization along the lower B2B Zone.

  • Demonstrates the potential to extend high-grade mineralization both laterally and at depth.

  • Strengthens confidence in the three-dimensional geometry of the lower B2B breccia while identifying opportunities for further expansion to the northwest and at depth.

• ATXD31B intersected 146m of 1.14% CuEq (0.70% Cu, 0.42 g/t Au), within a broader interval of 408m of 0.88% CuEq (0.58% Cu, 0.28 g/t Au), confirming thickness, continuity and northern extent of mineralization within the B2B system.

  • Further defined the northern margin of the B2B breccia while demonstrating continuity as the high-grade breccia transitions into the surrounding mineralized porphyry.

  • Hole ended in mineralized porphyry with assays pending, highlighting the potential to further expand the B2B system beyond the currently reported interval.
