ATEX Record Phase VI Program Expands the High-Grade B2B Breccia Strike by 50% and Discovers New Mineralization Beyond B2B to the East and North

ATEX Resources Inc. (ATX) released a summary of its Phase VI drilling program and geological interpretation updates on September 16, 2026. This release does not contain new assay results; the key intercepts were previously disclosed in releases dated between December 2025 and August 2026.

Phase VI involved approximately 28,400 meters of directional diamond drilling, exceeding the 25,000-meter target and representing an increase of more than 70% from Phase V. Highlights from the program include the following intercepts:

• ATXD25C returned 40 m at 4.83% CuEq within 86 m at 3.84% CuEq.
• ATXD26B returned 186 m at 2.15% CuEq within 887 m at 1.06% CuEq.
• ATXD32 returned 56 m at 2.36% CuEq within 592 m at 1.04% CuEq and 1,080 m at 0.89% CuEq.
• ATXD23C returned 20 m at 4.10% CuEq within 78 m at 3.03% CuEq.

The company stated that the B2B high-grade breccia strike length increased by 50% to approximately 600 meters. The broader mineralized corridor expanded approximately 200 meters to the east, and a 150-meter true-width zone of mineralized host rock was identified north of B2B. Additionally, porphyry-related mineralization is now established across an approximate 1.8-kilometer north-south corridor.

Phase VII is expected to begin in early October 2026, with an updated Mineral Resource Estimate targeted for the second half of 2027. The release also announced the appointment of a new Corporate Secretary.

ATEX Resources Inc. (ATX) released a wrap-up of its recent exploration program that contains no new material assay information. The headline intercepts were already known to the market, and the new geological interpretation along with east and north extension claims are incremental. Where assayed, these new findings are below economic grade.

The stock’s recent performance reflects these expectations. Shares rose from approximately C$2.40 in September 2025 to a high of C$4.38 in February 2026 as the largest B2B intercepts were released. Since then, the stock has round-tripped, falling to C$2.15 in July 2026 before currently trading at C$2.37.

The prior high-grade anchor is no longer being priced as aggressively. This release serves as a reminder that the high-grade B2B system exists, with Phase VII still ahead, rather than representing a disappointment against an embedded premium or a positive surprise.

At a market capitalization of roughly C$890 million and with a 1.5 billion tonne Inferred resource already on the books, this program wrap-up does not change the equity story. The likely share-price response is limited.

ATEX Resources Inc. (ATX) is a copper-gold exploration company advancing the Valeriano project in the Atacama Region of Chile. The project is a porphyry copper-gold system featuring a high-grade breccia zone known as B2B. The company holds a land position of approximately 25,000 hectares, which includes the Nuevo Horizonte claims.

Resource estimates for the project include an Indicated Resource of 475 million tonnes at 0.88% CuEq and an Inferred Resource of 1,511 million tonnes at 0.75% CuEq. The high-grade B2B zone comprises 28.4 million tonnes of Indicated material at 1.36% CuEq and 2.6 million tonnes of Inferred material at 1.05% CuEq. The porphyry core contains 118 million tonnes of Indicated material at 1.07% CuEq and 161 million tonnes of Inferred material at 1.01% CuEq.

Financially, ATEX Resources Inc. reported approximately C$141 million in cash as of June 30, 2026, according to the provided investor presentation. The company’s Q1 2026 balance sheet showed C$155.6 million in cash. While the majority-owned metal resources are large, they remain pre-feasibility stage; no mine plan, net present value, or production guidance has been provided.
