ATEX Resources Inc. reports exploration and corporate developments tied to the Valeriano Copper-Gold Project in the Atacama Region of Chile. News commonly centers on diamond drilling, assay results, copper-equivalent intervals, the B2B Zone, porphyry mineralization, and the scale of the mineralized system within the regional copper-gold porphyry belt between the El Indio and Maricunga belts.
Company updates also cover governance and leadership appointments, stock-option grants, health and safety matters, project operating status, and public-market listing or capital-structure developments affecting ATEX common shares on Canadian and OTC markets.
ATEX Resources (ATXRF) reported record Phase VI drilling results at the Valeriano Copper-Gold Project and outlined plans for Phase VII starting in early Q4 2026.
Phase VI totaled approximately 28,400m of diamond drilling, above the 25,000m target and over 70% more than Phase V, while directional drilling and wedging saved about 12,000m of drilling. The high-grade B2B breccia strike was expanded by roughly 50% to about 600m, with high-grade intercepts such as 40m at 4.83% CuEq in ATXD25C and 186m at 2.15% CuEq in ATXD26B. Drilling extended mineralization up to 200m east of B2B, outlined an approximate 150m true-width mineralized host-rock zone north of B2B, and established porphyry-related mineralization along an estimated 1.8 km north-south corridor, which remains open.
Phase VII will target further B2B and porphyry extensions at Valeriano and may test regional targets including Nuevo Horizonte, ahead of an updated Mineral Resource Estimate planned for 2H 2027.
ATEX Resources (OTCQX: ATXRF) reported final Phase VI drill assays from the Valeriano copper-gold project in Chile, extending the high-grade B2B breccia approximately 200 metres south in hole ATXD19A and increasing interpreted strike length by about 50% to roughly 600 metres.
Key results include ATXD19B ending in 37m of 1.72% CuEq within 446m of 0.74% CuEq, ATXD25E with 884m of 0.79% CuEq including 294m of 1.05% CuEq, and ATXD31B/31C refining the northern margin and geometry of B2B while outlining an interpreted 150m true-width mineralized rhyolite zone to the north. New porphyry-style alteration and mineralization more than 400m north (ATXD37) and mineralization to the south (ATXD39A) suggest broader system extent. Phase VII drilling is planned ahead of an updated mineral resource targeted for 2H 2027.
ATEX Resources (OTCQX: ATXRF) announced a finance leadership change, with Chief Financial Officer Elijah Tyshynski stepping down to pursue another opportunity.

ATEX continues to advance its flagship Valeriano Copper-Gold Project in Chile, which, as of September 23, 2025, had an Indicated Mineral Resource of 475 Mt at 0.88% CuEq and an Inferred Mineral Resource of 1,511 Mt at 0.75% CuEq.
ATEX Resources (OTCQX: ATXRF) reported new Phase VI drilling results from the Valeriano copper-gold project in Chile, including some of the highest-grade B2B breccia intervals to date.
Hole ATXD23C cut 20m of 4.10% CuEq within 78m of 3.03% CuEq and 124m of 2.65% CuEq. ATXD31A and ATXD31B confirmed continuity and thickness of mineralization to the north, with up to 408m of 0.88% CuEq including 146m of 1.14% CuEq. Phase VI drilling totaled 28,400m, and the B2B breccia has now been traced over about 600m, a 50% strike-length increase. About 35% of assays remain pending.
ATEX Resources (OTCQX: ATXRF) reduced the net smelter return (NSR) royalty on its Valeriano project by 0.2%, from 2.5% to 2.3%. This comes via the sale of its 10% stake in SCMV for about $2.4 million, versus a 2023 purchase cost just over $1.5 million. ATEX keeps a right of first refusal on the remaining 2.3% NSR and reports no known royalty burden on the adjacent Nuevo Horizonte land package.
ATEX Resources (OTCQX: ATXRF) reported voting results from its June 22, 2026 Annual General and Special Meeting. About 262.5 million shares, or roughly 70% of outstanding shares, were represented.
