This milestone report validates the scale andgeological potential of the Redonda Project and underscores theCompany’s commitment to best practices, technical rigor, andtransparency in advancing its exploration activities. The report hasbeen prepared in accordance with the Canadian SecuritiesAdministrators’ NI 43-101 Standards of Disclosure for MineralProjects. The report incorporates results from the Company’s2025–2026 drill campaign, updated geophysical data, and historicaldrilling completed by Teck Resources Ltd. in 1979. “This report represents a majormilestone for Vanguard,” said David Greenway, CEO. “We now haveindependent confirmation of a large-scale copper-molybdenum system atRedonda, supported by both historical and modern drilling.Importantly, mineralization is strong, consistent, and remains open inmultiple directions and may represent the upper portion of a muchlarger porphyry system. With a clear exploration roadmap and definedtargets, we believe Redonda has the potential to evolve into asignificant discovery in British Columbia.” Project Location & GeologicalSetting The Redonda Project comprises nine mineral claimstotaling 2,746.46 hectares on West Redonda Island, approximately 40 kmnortheast of Campbell River. The property is accessible year-round viabarge and supported by established logging infrastructure. Geologically, Redonda lies within the Coast Suture Zonebetween the Wrangellia Terrane and the Coast Plutonic Complex.Copper-molybdenum mineralization is associated with a hornblendeporphyry dike and breccia zones, consistent with porphyry-stylesystems observed elsewhere in southwestern British Columbia.

Drilling & Exploration Overview The report integrates multiple exploration phases, including historical drilling, re-assaying of legacy core, and Vanguard’s 2023–2026 drill programs, along with airborne geophysical surveys. Key Highlights from the NI 43-101 Report - Large-Scale Mineralized SystemDefined: Drilling outlines a mineralizedfootprint exceeding approximately 600 metres in strike, 500 metres inwidth, and 300 metres vertically. - Broad Intervals of Copper-MolybdenumMineralization: Multiple drill holes intersectedlong intervals of mineralization, including zones exceeding 100 metresin length with consistent grades. - Near-Surface MineralizationIdentified: Several drill holes encounteredmineralization beginning near surface, supporting favorableexploration geometry. - Geological Model Confirmed andStrengthened: Recent drilling supports amulti-phase intrusive and breccia-hosted porphyry system with amineralized core. - Expansion Potential RemainsOpen: Mineralization remains open at depth andalong strike, indicating potential for a larger underlying system. Disclaimer – Drill Compilation: Management cautions that the presented drill sample results are historical in nature, and Vanguard has not undertaken any independent investigation of the sampling, nor has it independently analyzed the results of previous exploration work to verify the results. Vanguard considers these results relevant for planning future exploration programs. All drill intercepts represent drilled lengths, and insufficient information exists to determine true widths. The technical information is derived from publicly available government sources. Disclaimer – Initial Exploration Target: The potential quantity and grades are conceptual in nature. There has been insufficient exploration drilling to define a mineral resource, and it is uncertain whether further exploration will result in the delineation of a mineral resource. Technical Report & Exploration Strategy The report recommends a two-phase exploration program: Phase 1: Induced Polarization (IP) geophysical survey, detailed mapping, and geochemical sampling to refine drill targets. Phase 2: Approximately 2,800 metres of diamond drilling across seven holes to test priority targets and expand mineralization. Figure 2: Diagrammatic Illustration of Conceptual model illustrating the linkages between porphyry and high/low sulphidation epithermal mineralization (from Corbett, 2017) Conceptual Geological Model The Redonda Project is interpreted within the context of a porphyry-epithermal system, as illustrated in the conceptual model of Steve Corbett (2017). This model highlights the genetic relationship between deeper porphyry copper-molybdenum mineralization and overlying high- and low-sulphidation epithermal environments. At Redonda, observed features such as multi-phase intrusions, brecciation, quartz stockwork veining, and chalcopyrite-molybdenite mineralization are consistent with the upper levels of a porphyry system. The presence of breccia-hosted mineralization and alteration patterns suggests that the current drilling may be testing the upper portions of a larger hydrothermal system, with potential for a more robust mineralized core at depth. This conceptual framework supports continued exploration targeting both lateral and vertical extensions of the system. The Redonda Copper-Molybdenum Project Technical Report was prepared by W.B.

About Redonda The Redonda Project is a district-scale copper-molybdenum exploration asset comprising 2,746.46 hectares across nine contiguous mineral claims, located approximately 40 km northeast of Campbell River, British Columbia. The property benefits from excellent infrastructure, including year-round barge access and an established network of logging roads, supporting efficient and cost-effective exploration. Redonda is situated within the highly prospective Coast Suture Zone, a prolific geological corridor known for hosting significant porphyry copper systems in southwestern British Columbia. The Project exhibits key geological features associated with large-scale porphyry deposits, including multi-phase intrusive activity, extensive brecciation, and strong copper-molybdenum mineralization. Mineralization is centered along a broad hornblende porphyry dike system, where drilling and surface work have identified widespread sulphide mineralization within brecciated zones and stockwork veining. These features, combined with evidence of a robust hydrothermal system, support the interpretation that Redonda may represent the upper portion of a larger porphyry center. Importantly, the Project shares geological similarities with nearby copper-molybdenum deposits, including OKover and Gambier, reinforcing its potential to host a significant mineralized system. With mineralization open in multiple directions and a growing database of drilling and geophysical data, Redonda represents a compelling exploration opportunity with strong discovery potential. The Company has established a solid permitting foundation and maintains positive engagement with local First Nations, positioning Redonda for continued advancement through systematic exploration.
