Toronto, Ontario--(Newsfile Corp. - February 24, 2025) - ATEX Resources Inc. (TSXV: ATX) ("ATEX" or the "Company") is pleased to announce updated partial assay results for holes ATXD16B and for ATXD23A as part of its Phase V exploration program at the Valeriano Copper Gold Project ("Valeriano" or the "Project"), located in the Atacama Region, Chile. To date, three drill holes have been completed, two testing the recently identified high-grade breccia mineralization ("B2B zone") and the third testing extensions along the high-grade porphyry ("Valeriano Porphyry") trend. An additional five drill holes are currently progressing with daily production reaching targeted rates.
Highlights include:
- ATXD16B intersected 220 metres ("m") of 1.00% copper equivalent ("CuEq") (0.75% Cu, 0.31 g/t Au, 1.2 g/t Ag and 90 g/t Mo) within a broader interval of 590m of 0.78% CuEq (0.58% Cu, 0.24 g/t Au, 0.9 g/t Ag and 96 g/t Mo) from 1,044m downhole with assays pending from 1,634m to final depth at 1,880m.
- ATXD16B is a daughter hole from ATXD16Ai which had intersected 852m of 0.82% CuEq (0.60% Cu, 0.28 g/t Au, 0.98 g/t Ag and 72 g/t Mo), 594m of 0.92% CuEq (0.67% Cu, 0.32 g/t Au, 1.13 g/t Ag and 71 g/t Mo) and 112m of 1.42% CuEq (1.01% Cu, 0.57 g/t Au, 2.06 g/t Ag and 46 g/t Mo) and extended the high-grade core of the porphyry approximately 120m to the southeast.
- The high-grade trend remains open to the south-southeast and represents an opportunity to further extend high-grade mineralization in further step-out holes.
- ATXD23A grades improved upon receipt of final by-product metal results, showing intersection of 152m of 2.12% CuEq (1.52% Cu, 0.75 g/t Au, 0.8 g/t Ag, 41 g/t Mo) within a broader interval of 342m of 1.52% CuEq (1.05% Cu, 0.47 g/t Au, 1.2 g/t Ag, 272 g/t Mo). Assays are pending from a depth of 1,584m to the end of the hole at 2,042m.
- Two rigs are currently dedicated to defining the high-grade breccia B2B zone with two others focused on infill drilling within the higher-grade Valeriano Porphyry units. The fifth rig will continue to provide optionality to test the current extents of known mineralization as illustrated in Figures 1-3.
"Our Phase V program continues to accelerate with five rigs turning as of the start of the new year," stated Ben Pullinger, President, and CEO of ATEX. "Both ATXD16B and ATXD23A continue to validate our view of the exploration potential within both the mineralized porphyry units and the overlaying high-grade breccia B2B zone. Drill production rates are stabilizing at forecasted rates despite significantly slower than anticipated assay turnaround times. So far in Phase V, Valeriano continues to surprise to the upside, and we look forward to providing additional results to the market very soon."
Phase V Update - Three Holes Completed, Five Holes Actively Drilling
To date, 7,455m have been drilled in the Phase V program with three holes completed including ATXD23A, ATXD16A and ATXD25A and an additional five holes actively drilling. Additional details on these holes are provided in the subsequent sections. Approximately 6,000m of drilling has been avoided by wedging from re-entered drill holes allowing for a significant reduction in costs and time. Daily metres drilled have increased notably to date in 2025 placing ATEX on track to achieve its targeted metres for the overall program. Holes ATXD23A, ATXD16B and ATXD25A have been completed with partial results for the high-grade B2B zone intersected in ATXD23A as previously released on January 23, 2025ii.
The recently discovered high-grade breccia B2B zone is a broad area ranging between 150m to 350m downhole and is hosted entirely within the overlaying wall rock unit. Mineralization within this zone occurs primarily as an overprinting hydrothermal alteration event (argillic over potassic) associated with disseminated sulphide and vein hosted chalcopyrite-bornite and bornite-chalcopyrite mineralization. Drilling to date has defined a strike length of approximately 400m and it remains open. Follow up drilling is currently testing the vertical continuity and further expansion of the B2B zone.
Preliminary logging indicates that ATXD16B has intersected broad intervals of mineralized porphyry which is similar to other mineralized sections in Phase IV drilling. ATXD25A has been completed and has intersected broad intervals of strongly mineralized (bornite-chalcopyrite) porphyry.

B2B Exploration
- ATXD23A (170°/-40°, completed at 2,042m) is a daughter hole approximately 100m along strike to the north of ATXD26iii, (68.0m of 2.02% CuEq (1.39% Cu, 0.60 g/t Au, 3.81 g/t Ag and 473 g/t Mo) within longer intervals of 356.0m of 0.98% CuEq (0.7% Cu, 0.29 g/t Au, 1.49 g/t Ag and 180 g/t Mo) and 978.0m of 0.75% CuEq (0.54% Cu, 0.21 g/t Au, 1.26 g/t Ag and 145 g/t Mo)). ATXD23A intersected the targeted B2B zone with higher-grade mineralization occurring from 1,036m to 1,378m associated with intense brecciation and alteration associated with bornite and chalcopyrite. The hole was completed in mineralized wall rock.
- ATXD27A (167°/-43°, ongoing at 1,790m) is a daughter hole from ATXD27 that was paused at 944 meters at the end of Phase IV. The target for ATXD27A is the northern extension of the breccia corridor, 140m to the north of where the target was intersected in ATXD26 and ATXD23A, and in an area never tested in drilling before. To date ATXD27A has drilled through host rocks and from 1,551m has entered a zone of alteration similar to that seen in drill holes ATXD23A and ATXD26. The hole will continue to a planned depth of 2,000m.
- ATXD23B (140°/-50°, ongoing at 1,804m) is a daughter hole from ATXD23A stepping out 100m above ATXD23A, and is situated approximately 100m along strike, to the north, of ATXD26. It is testing up-dip towards the surface. Over the interval from 1,180 to 1,200m, this hole intersected a zone of alteration and mineralization similar to that intersected 100m below in ATXD23A. The hole is planned to continue to a target depth of 2,000m.
Porphyry Exploration
- ATXD16B (266°/-75°, completed at 1,880m) is a daughter hole extending the high-grade porphyry trend by approximately 120m southeast along strike from ATXD16A (852m of 0.82% CuEq (0.60% Cu, 0.28 g/t Au, 0.98 g/t Ag and 72 g/t Mo), including 594m grading 0.92% CuEq (0.67% Cu, 0.32 g/t Au, 1.13 g/t Ag and 71 g/t Mo) and 112m of 1.42% CuEq (1.01% Cu, 0.57 g/t Au, 2.06 g/t Ag and 46 g/t Mo)iv. ATXD16B intersected the targeted mineralized porphyry (EP) at 1,264m through to 1,768m and was completed in mineralized wall rock.
- 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 northern most 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))v and intersected the targeted mineralized porphyry at 1,771m to its final depth 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.
- ATXD22C (257°/-74°, ongoing at 1,262m) is a daughter hole from ATXD22 designed to infill and increase the confidence level of the Inferred Mineral Resource, drilling at nominal 150 metre centres on previously defined high-grade zones within the existing porphyry footprint. This hole is currently still drilling through host rock sequences.
- ATXD25B (092°/-47°, ongoing at 1,031m) is a daughter hole from ATXD25 and a follow-up to ATXD25A. The hole is designed to test mineralized intersections approximately 200m up-dip. The drill hole is currently in the host rocks and is due to commence directional drilling shortly.
- ATXD28 (293°/-76°, ongoing at 1,270m) is a parent hole from the same platform as ATXD19 drilled from surface. The hole is designed to infill drill to increase confidence in the Inferred Mineral Resource, drilling at nominal 150 metre centres on previously defined high-grade zones within the existing porphyry footprint. The drill hole is currently passing through host rock.
The outstanding results from ATXD23A and ATXD16B are expected later this month.
