Toronto, Ontario--(Newsfile Corp. - June 23, 2026) - ATEX Resources Inc. (TSX: ATX) (OTCQX: ATXRF) ("ATEX" or the "Company") is pleased to announce that it has reduced the net smelter return royalty ("NSR") on the Valeriano project by 0.2%, from 2.5% to 2.3%, as partial consideration for the sale of its 10% stake in Sociedad Contractual Minera Valleno ("SCMV"), a private Chilean Company. As part of the transaction, the Company also received approximately $2.4 million in cash for the shares of SCMV it had purchased in 2023 for just over $1.5 million. ATEX retains a right of first refusal ("ROFR") on the remaining 2.3% NSR. The Company additionally notes that there is no known royalty burden on the adjacent Nuevo Horizonte land package that includes two potential porphyry targets with similar geological features observed at Valerianoⁱ.

Chris Beer, Interim President and Chief Executive Officer, commented, "We are very pleased with the outcome to have the NSR royalty burden reduced on the Valeriano project, while at the same time realizing a positive return on a past investment. Opportunities to reduce an NSR royalty while generating proceeds are exceptionally rare. SCMV was instrumental in introducing the Valeriano project to ATEX, and both parties have benefited from the growth of the Company over the past several years. By transferring our investment in SCMV to the existing shareholders, and reducing the NSR, both organizations can continue focusing on their respective operations with greater simplicity."

Background

On January 23, 2023, the Company, through its fully owned subsidiary ATEX Valeriano SpA, acquired a 10% equity interest in SCMV, the historic optionor of the Valeriano project, from a third party, for a purchase price of $1,538,868 (US$1,150,000). As a result of this acquisition, the Company became an indirect owner of 10% of all assets held by SCMV. At the time of the acquisition, SCMV held a 2% NSR on the Valeriano project, along with shares in ATEX, which were issued to SCMV previously and related to initial payments made by ATEX when entering into the option on the Valeriano project ("Valeriano Option"). Subsequent to the acquisition of the 10% equity interest in SCMV, ATEX issued additional shares to SCMV upon the completion of the Valeriano Option by ATEX in December of 2024.ⁱⁱ Further details regarding these historical transactions can be found in the Company's Annual Information Form for the year ended December 31, 2025.ⁱⁱⁱ

The 10% equity interest in SCMV, along with the cash and equities held by SCMV, translated to an effective ownership by ATEX of 0.2%, of the 2% NSR outstanding. Through exiting the interest in SCMV, ATEX was able to extract and cancel the 0.2% NSR, leaving SCMV with a 1.8% NSR on the Valeriano project. The remaining 0.5% NSR, in addition to the 1.8% NSR held by SCMV, is held by two unrelated third parties, for a total NSR of 2.3% on the Valeriano project. As noted above, ATEX retains a ROFR on the remaining NSR.
