Vanguard Mining Reports Re-Assay Program for Redonda Copper-Molybdenum Project (TheNewswire) Vancouver, BC – February 2, 2026 – TheNewswire - Vanguard Mining Corp. ("Vanguard" or the "Company") (CSE: UUU | OTC: UUUFF | FSE: SL51) is pleased to announce that the Company plans to undertake additional re-assaying of selected drill core using industry-standard multi-element analytical methods, including four-acid digestion with ICP-MS and ICP-AES, to further evaluate gold, copper, silver, rare earth, and other associated elements. This work is intended to enhance the Company’s understanding of the Copper Equivalent (“CuEq”) values derived from the recently completed drill program at its 100%-owned Redonda Copper-Molybdenum Project (the “Project”), located in the Vancouver Mining Division, approximately 40 kilometres northeast of Campbell River, British Columbia. David Greenway, CEO of Vanguard Mining Corp., commented: “With sustained strength in silver, gold and copper prices, the underlying value of mineralized rock is increasing. Advances in laboratory technology and analytical methods, combined with systematic drilling, provide an opportunity to re-evaluate historical data and re-assaying material using modern techniques. The planned Phase 2 drill program will build on the 2025 results at Redonda, while re-assaying and updated geological work are intended to help better define and unlock the project’s mineral potential as exploration continues in 2026.” 2026 Drill Program As previously announced on January 27, the additional re-assaying will support the advancement of the planned Phase 2 Drill and Exploration Program (the “Drill Program”), which is expected to include: The Drill Program is fully permitted and is being advanced to build upon the encouraging results from the Company’s recently completed drill program at the Project. The Drill Program is currently anticipated to include: Reconnaissance-scale Induced Polarization (“IP”) surveying to better define and vector toward zones of higher-grade copper-molybdenum mineralization; Drilling of up to seven (7) diamond drill holes totaling up to approximately 2,800 metres, targeting the southeast portion of the Project between and beyond historical TECK drill holes; Detailed geological mapping and prospecting will be conducted to the north and west within the Project’s megabreccia zone to identify additional priority drill targets. Results from the Phase 1 drill program, geophysical surveys, historical drilling, and new geological mapping will be integrated to refine targeting and guide ongoing exploration activities. The Drill Program is designed to test extensions of known copper-molybdenum mineralization and evaluate new target areas within the broader mineralized system. Exploration activities will be carried out in accordance with applicable permits, environmental best practices, and regulatory requirements. Field logistics are expected to include either an expanded exploration camp or accommodation through an existing floating logging camp in the area. Vanguard will continue to work closely with the Klahoose First Nation throughout the program, prioritizing ongoing engagement, economic participation opportunities, and collaboration with Klahoose-owned service providers, including a Klahoose-owned logging company where practicable. The Drill Program is being planned on an accelerated timeline to rapidly follow up on the recently announced drilling results, which confirmed a significantly expanded copper-molybdenum mineralized system at Redonda. In addition to copper and molybdenum, the Company will continue to evaluate the potential presence and significance of rhenium as a possible by-product associated with molybdenite mineralization, where appropriate, as exploration advances. About Redonda The Redonda Project comprises nine mineral claims totaling 2,746.46 hectares, located approximately 40 kilometres northeast of Campbell River, British Columbia. The property is accessible year-round via scheduled barge service from Campbell River, with on-site access provided by approximately 5 kilometres of recently upgraded logging road from Redonda Bay. Active forestry operations maintain an extensive network of forest service roads across the claims. Redonda lies within the Coast Suture Zone between the Wrangellia Terrane and the Coast Plutonic Complex. Early Cretaceous dioritic intrusions of the Coast Plutonic Complex are cut by at least three later intrusive phases: (i) a quartz plug; (ii) a wide, hornblende-rich dike locally brecciated over approximately 600 metres of exposed strike length; and (iii) several smaller feldspar dikes near the southwestern margin of the hornblende body. Copper-molybdenum mineralization is most strongly developed along the hornblende-rich dike, particularly within brecciated zones.
