Vanguard Mining Corp. Reports 2025 Redonda Drill Results; Cross-Section Confirms Copper-Molybdenum System More Than Doubles in Size (TheNewswire) Vancouver, BC – TheNewswire - January 26, 2026 – Vanguard Mining Corp. ("Vanguard" or the "Company") (CSE: UUU | OTC: UUUFF | Frankfurt: SL51) is pleased to announce assay results from its recently completed Phase 1 of its 2025 diamond drilling program, which included Holes 25-01 and 25-02 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. 2025 Drill Results Highlight System Growth Hole 25-01, drilled at a dip of -65°, intersected extensive copper-molybdenum mineralization over much of its length: From 3.05 m to 29.12 m (27.07 m), a weighted average of 0.3252% copper and 78 ppm molybdenum From 37.65 m to 387.70 m (350.05 m), a weighted average of 0.244% copper and 112 ppm molybdenum These intercepts extend the higher-grade mineralized zone by an additional 199.05 metres, more than doubling the length of higher-grade mineralization intersected in the 2023 drilling in cross-section. Hole 25-01 reached a total depth of 510.74 metres and returned a weighted average grade of 0.1801% copper and 86 ppm molybdenum over its entire length. Lower-grade mineralization continues beyond the end of the hole, indicating the system remains open at depth. Hole 25-02, drilled vertically and located approximately 30 metres east of the 2023 drilling, intersected: From 3.05 m to 132.00 m (129.26 m), a weighted average of 0.1344% copper and 128 ppm molybdenum Together, these results demonstrate that copper-molybdenum mineralization at Redonda is laterally and vertically extensive in cross-section. A valid drill permit is currently in place, allowing for continued drilling at the Project during the 2026 exploration season.

Samples were submitted to ALS Canada Ltd. (“ALS Laboratories”) for geochemical analysis. Industry-standard quality assurance and quality control protocols were employed, including the insertion of certified reference materials and blanks at regular intervals within the sample stream.

The 2025 drilling successfully expanded the mineralized system well beyond the limits of the 2023 program, confirming continuity and scale. As copper demand continues to grow in support of the global energy transition, results such as these reinforce our belief that Redonda has the potential to host a large copper-molybdenum system. With a drill permit in place, we are well positioned to advance the project through additional drilling in 2026 and continue unlocking value for shareholders.” The 2025 drill program was guided by targets and structural corridors interpreted from a previously announced airborne geophysical survey conducted by Precision GeoSurveys, Inc. (“Precision”), integrated with historical drilling and surface sampling data. As reported by the previous operator, Stamper Oil & Gas Corp. (“Stamper”), in a January 25, 2024 news release, historical drilling at Redonda intersected intervals of up to 142.6 metres grading 0.279% Cu and 0.0281% Mo, while surface sampling returned near-surface intervals ranging from 3.1 metres to 48 metres grading up to 0.529% CuEq. These results are historical in nature and should not be relied upon as an indication of current mineral resources or mineral reserves. Copper equivalent (“CuEq”) values are provided for illustrative purposes only and were calculated using metal prices and recovery assumptions disclosed in the January 25, 2024, Stamper news release.
