ATEX Intersects 44 Metres Of 1.00% Cueq Expanding B2B Zone Updip And Along Strike

(MENAFN- Newsfile Corp) Toronto, Ontario--(Newsfile Corp. - April 22, 2025) - ATEX Resources Inc. ( TSXV: ATX ) (" ATEX " or the " Company ") is pleased to provide an update on its Phase V program at the Valeriano Copper Gold Project (" Valeriano " or the " Project "), located in the Atacama Region, Chile. The Company currently has five diamond drill rigs operating, nine holes completed and another five in progress. To date, ATEX has completed approximately 13,700 metres of drilling in the Phase V program. ATEX is also pleased to announce the appointment of Elijah Tyshynski as Chief Financial Officer and Corporate Secretary effective May 1, 2025. Mr. Tyshynski brings to ATEX decades of experience inclusive of the mining sector and within the international capital markets, a valuable skillset as Valeriano advances to the next stage.

Highlights include:

• Completed assay results for ATXD25A including the previously announced highest-grade intersection of 30 metres ("m") of 4.40% copper equivalent ("CuEq") (2.21% Cu, 3.17 g/t Au, 15.1 g/t Ag, 3 g/t Mo)within a broader interval of 108m of 1.69% CuEq (0.87% Cu, 1.18 g/t Au, 5.5 g/t Ag and 9 g/t Mo) and 602m of 0.54% CuEq (0.40% Cu, 0.16 g/t Au, 1.0 g/t Ag, 57 g/t Mo), from 1,230m downhole^[i].
  • From 1,892m to 1,922m, the 30m interval grading 4.40% CuEq is the highest-grade and northernmost intersection encountered within the mineralized porphyry to date, therefore extendingthe previously identified high-grade trend by 200m to a length of ~1,000m and the trend remains open to the north.

  • ATXD25B will be targeting the updip extension of the high-grade interval intersected in ATXD25A exploring for potential continuity of a structural control linking ATXD25A to the B2B breccia zone approximately 1,000m above.

• ATXD23B targeting the B2B zone intersected 44m grading 1.00% CuEq (0.83% Cu, 0.21 g/t Au, 1.4 g/t Ag, 36 g/t Mo) within a broader interval of 210m of 0.83% CuEq (0.60% Cu, 0.21 g/t Au, 1.0 g/t Ag, 210 g/t Mo) from 1,028m downhole.
  • ATXD23B targeted 100m updip of high-grade intersections in the B2B breccia from drill hole ATXD23A. The 210m (from 1,028m to 1,238m) interval grading of 0.83% CuEq and located in the B2B breccia confirms the vertical extension of this highly mineralized unit.

  • The highly mineralized B2B zone remains open updip and along strike .

• ATXD27A intersected 42m of 1.20% CuEq (0.84% Cu, 0.49 g/t Au, 3.1 g/t Ag, 9 g/t Mo) from 1,638m to 1,776m downhole, extending the strike length of the B2B zone by ~140m north of ATXD23A; additionally a second zone of 32m of 1.00% CuEq (0.77% Cu, 0.31 g/t Au, 1.7 g/t Ag, 19 g/t Mo) from 1,888m to 1,920m was also intersected.

• Elijah Tyshynski to join as Chief Financial Officer and Corporate Secretary bringing to ATEX extensive senior level corporate, capital markets and financing experience.

"Today's results continue to showcase the significant grades and widths achievable by the B2B zone and the broader Valeriano deposit which still remains open in all directions," stated Ben Pullinger, President and CEO of ATEX. "The high-grade porphyry trend now measures approximately 1,000m along strike and remains open. The B2B breccia zone continues to grow and remains a key focus for exploration as it has the potential to materially enhance the grade and potential economic profile for Valeriano. Through the rest of the program, we will be zeroing in on the broader structural controls, that not only host the B2B breccias but have the potential to host further breccia bodies currently suggested by our geophysical data. These will be a priority for Phase VI."

Mr. Pullinger continued, "I am also excited to have Elijah Tyshynski join our team. His strong finance track record most recently at O3 Mining up until the acquisition by Agnico Eagle Mines and international experience will be critical as we continue to advance the Valeriano project. In addition, I also want to thank Sheila Magallon for her many contributions to the Valeriano Project and ATEX over her tenure as CFO. We wish her all the best in her future endeavours."

Elijah Tyshynski Joins ATEX as Chief Financial Officer and Corporate Secretary

Effective May 1, 2025, Mr. Tyshynski joins ATEX following the sale of O3 Mining ("O3") to Agnico Eagle Mines ("Agnico"), where he acted as O3's Chief Financial Officer and Corporate Secretary. During his time with O3, he oversaw financial and regulatory reporting, financings, implementation of internal policies and processes, and the eventual transaction with Agnico. Prior to, and during his time with O3, Mr. Tyshynski worked with Osisko Mining as the Director of Strategic Development, along with providing capital markets and strategic advice to other companies within the Osisko Group. Mr. Tyshynski has extensive capital markets and infrastructure financing experience, having held the position of Senior Portfolio Manager at Ontario Teachers Pension Plan, Head of Trading for the Standard Bank of South Africa in Johannesburg, and Vice President of Emerging Market Trading for both Morgan Stanley and Royal Bank of Canada in London, England.

Phase V Update - Nine Holes Completed, Five Holes Actively Drilling

To date 13,700m has been completed in the Phase V program with nine holes including ATXD16B, ATXD23A, ATXD25A, ATXD23B, ATXD25B, ATXD27A, ATXD22C, ATXD28, and ATXD29 being completed, and an additional five holes actively drilling. Additional details on these holes are provided in the subsequent sections. Using directional drilling techniques and drilling daughter holes, ATEX has saved approximately 9,200m of drilling, compared to conventional drilling, resulting in a much more effective and efficient program. Current and subsequent drill holes will continue to target infill, extensional (Figure 1 & 2), and high-grade breccia targets (Figure 1, 2 & 3).

B2B Exploration

• ATXD23B (140°/-50°, completed at 1,999m) is a daughter hole from ATXD23A stepping out 100m above ATXD23A, and is approximately 100m along strike, to the north, of ATXD26. The drill hole targeted updip extensions, toward surface, of high-grade mineralization intersected in ATXD23A. From 1,723m to 1,897m, this hole intersected a zone of alteration and mineralization like that intersected 100m above in ATXD23A. Results returned and reported here support the interpretation of the extension of the B2B breccia updip of ATXD23A. Associated with this mineralized intercept, and from 1,028m to 1,318m downhole is a zone of widespread disseminated bornite mineralization which will be followed up on in Phase VI. (Released today)

• ATXD27A (167°/-43°, completed at 2,148m) is a daughter hole from ATXD27 that was paused at 944 meters at the end of Phase IV. The target for ATXD27A was the northern extension of the breccia corridor, 140m to the north of where the target was intersected in ATXD23A, and in an area never tested before. ATXD27A drilled through host rock and from 1,043m to 1,397m and entered a zone of alteration like that seen in drill holes ATXD23A and ATXD26. The hole was completed at a length of 2,148m ending in early porphyry with chalcopyrite-bornite mineralization. (Released today)

• ATXD27B (149°/-47°, ongoing at 1,257m) is the second daughter hole from ATXD27. The hole is currently drilling in mineralized host rock and will be targeting the B2B zone 150m to the northeast of the high-grade breccia intersected in ATXD26 and ATXD23A.

• ATXD29A (173°/-74°, ongoing at 1,154m) is a daughter hole from ATXD29 and is targeting the B2B breccias approximately 100m updip from the intersections drilled in ATXD26 and ATXD23A.

• ATXD25C (098°/-66°, ongoing at 887m) is a daughter hole from ATXD25A and is designed to test the potential link between the B2B breccia and the high-grade bornite zone intersected in ATXD25A.

Valeriano Porphyry Exploration

• ATXD25A (102°/-47°, completed at 2,232m) continued from where it was paused at the end of Phase IV at a depth of 1,454m, targeting the northernmost extensions of the known mineralized footprint. ATXD25A is a daughter hole to the north of ATXD25 (862.2m of 0.62% CuEq (0.42% Cu, 0.27 g/t Au, 1.72 g/t Ag and 26 g/t Mo), including 114m of 0.88% CuEq (0.54% Cu, 0.48 g/t Au, 2.95 g/t Ag and 6 g/t Mo), within a broader interval of 350.2m grading 0.75% CuEq (0.45% Cu, 0.42 g/t Au, 2.60 g/t Ag and 3 g/t Mo))ⁱⁱ and intersected the targeted mineralized porphyry at 1,771m to its final downhole length of 2,232m. A bornite bearing hydrothermal breccia zone was intersected from 1,892m to 1,902m, and the hole was completed at 2,232m downhole achieving a new record hole length at Valeriano. As this deeper hydrothermal breccia is directly below intersections in the B2B breccias, it could possibly be a feeder zone to these intersections. (Partial assays released on March 18, 2025ⁱⁱⁱ)

• ATXD25B (092°/-47°, completed at 1,837m) is the second daughter hole from ATXD25 located 250m along strike from and following-up to ATXD25A. The hole was designed to test mineralized intersections approximately 200m updip. ATXD25B intersected disseminated zones of potassic alteration from 1,340m downhole, chalcopyrite from 1,337m to 1,837m and bornite from 1,249m to 1,646m. (Assays pending)

• ATXD22C (257°/-74°, completed at 1,814m) is a daughter hole from ATXD22, designed to infill drill and increase the confidence level of the Inferred Mineral Resource, drilling at nominal 150m centres on previously defined high-grade zones within the existing porphyry footprint. The hole intersected mineralized porphyry at 1,375m downhole, early porphyry from 1,580m to 1,666m, and was completed in mineralized porphyry. (Assays pending)

• ATXD28 (293°/-76°, completed at 1,924m) is a parent hole from the same platform as ATXD19 and is being drilled from surface. The hole is designed to infill drill on previously defined high-grade zones within the existing porphyry footprint to increase confidence in the Inferred Mineral Resource, drilling at nominal 150m centres. The drill hole intersected early porphyry from 1,246m to 1,276m and is currently drilling in mineralized porphyry. (Assays pending)

• ATXD22D (217°/-72°, ongoing at 1,490m) is a daughter hole from ATXD22C and is designed to test early porphyry mineralization on nominal 150m centres as part of the infill program.

• ATXD28A (311°/-76°, ongoing at 1,297m) is a daughter hole from ATXD28 and is designed to test early porphyry mineralization on nominal 150m centres as part of the infill program.

Quality Control & Quality Assurance

Drill holes are collared with a PQ drill bit, reduced to HQ and, sequentially, to NQ as the drill holes progressed deeper. Drill core produced by the drill rigs was extracted from the core tubes by the drill contractor under the supervision of ATEX employees, marked for consistent orientation and placed in core boxes with appropriate depth markers added. Full core boxes were then sealed before being transported by ATEX personnel to the Valeriano field camp. Core at the field camp is processed, quick logged, checked for recovery, photographed, and marked for specific gravity, geotechnical studies and for assays. From camp, the core is transferred to a secure core-cutting facility in Vallenar, operated by IMG, a third-party consultant. Here, the core trays are weighed before being cut using a diamond saw under ATEX personnel oversight. ATEX geologists working at this facility double-check the selected two-metre sample intervals, placing the samples in seal bags and ensuring that the same side of the core is consistently sampled. Reference numbers are assigned to each sample and each sample is weighed. The core trays with the remaining half-core are weighed and photographed. Additionally, core logs are updated, and specific gravity and geotechnical samples are collected. The remaining core is stored in racks at the Company's secure facility in Vallenar.

From Vallenar samples are sent to an ALS preparation facility in La Serena. ALS is an accredited laboratory which is independent of the Company. The prepared samples were sent to the ALS assay laboratories in either Santiago, Chile and Lima, Peru for gold (Au-AA24), copper (Cu-AA62), molybdenum (Mo-AA62) and silver (Ag-AA62) assays as well as and multi-element ICP (ME-MS61) analysis. No data quality problems were indicated by the QA/QC program.
