Vanguard Mining Company (Uuu: own search engine; UUUFF:outside; SL51: Frankfurt) has submitted its first independent technical report NI 43-101 for the 100% owned Brussels Creek Project located in the Kamloops Mining Division of south-central British Columbia.
The technical report, effective March 30, 2026, was prepared in accordance with NI 43-101 standards by Jeremy Hanson, P.Geo., of Hardline Exploration Corp., an independent qualified person, and represents an important milestone in the development of Vanguard’s portfolio of high-potential exploration assets.
David Greenway, CEO of Vanguard, commented: “The submission of our first NI 43-101 technical report for the Brussels Creek Project represents an important milestone for Vanguard, establishing a strong technical foundation for the development of this highly prospective gold and copper asset in British Columbia. Located adjacent to New Gold’s New Afton Mine within a belt of prolific porphyry, Brussels Creek reinforces our confidence in the geological potential of the project.
With 100% ownership, we are well positioned to drive exploration and unlock value through disciplined, data-driven programs. The identification of a porphyry-pyroclastic system, supported by encouraging gold and copper anomalies, highlights the scale of the opportunity. This technical report provides a clear path forward as we move towards targeting drilling and potential discovery, with the goal of delivering long-term shareholder value.
Technical Report Highlights: Vanguard has a 100% interest in 16 mineral claims totaling approximately 1,227.6 hectares, subject to a 2% NSR charge. Primary Mining Jurisdiction: Located approximately 25 km west of Kamloops, British Columbia, with excellent access to infrastructure, services and skilled labor.
Prolific geological environment: Located within the Quesnel Terrane, it hosts major porphyry copper and gold deposits, including the nearby New Afton Mine.
Gold-Copper System Identified: Geological, geochemical and structural data support a potential porphyry-pyroclastic system for gold and copper mineralization.
Encouraging geochemistry: Soil samples showed values up to 88 ppb gold and 221 ppb copper, with anomalies of antimony and mercury.
Multiple target areas: Specific central and eastern anomalous zones highlight priority exploration areas.
Significant Upside Discovery: An early-stage project with no specific resources, offering strong potential for new discoveries.
Exploration Summary: The technical report highlights a long history of exploration at Brussels Creek dating back to 1969, including geochemical surveys, geophysical programs and limited drilling campaigns that together demonstrate the project’s enduring potential.
Recently, the 2025 Vanguard Exploration Program represented a significant step forward, successfully identifying multi-element gold and copper anomalies associated with hydrothermal alteration and quartz veining. These results are consistent with the model of strong porphyry and surface layer mineralization and enhance the project’s ability to host a large-scale mineralization system.
Integrating historical data with recent geochemical and geological results has greatly enhanced understanding of the project and confirmed the presence of an active mineral hydrothermal system. Importantly, this work has identified several high-priority target areas with strong geochemical signatures and favorable structural settings, providing a clear path towards systematic follow-on exploration and targeting drilling.
Recommended Next Steps: Building on the strong technical foundation established in the first technical report, NI 43-101, the qualified person has identified a focused Phase 1 exploration program designed to rapidly advance the Brussels Creek Project toward drill-ready targets.
This next phase of work aims to fully unleash the project’s gold and copper potential by improving and expanding high-priority target areas through a combination of advanced geophysics, expanded geochemistry and detailed field work, including induced geophysical (IP) surveys: high-impact IP surveys over priority areas to identify and quantify chargeability anomalies that may represent sulphide-rich mineral systems at depth.
Extended soil geochemical coverage: Infill and exhumation sampling to enhance and expand known gold and copper anomalies and direct them towards potential mineral centres.
Mapping and Geological Prospection: Targeted field programs to further define alteration systems, structural controls and surface expressions of mineralization across the project.
This integrated approach is designed to enhance rapid target identification, prioritize areas with the highest potential, and position Brussels Creek for a potential inaugural drilling program.
With an estimated budget of approximately $155,000, the Phase 1 program represents a cost-effective opportunity to significantly de-risk the project while progressing toward discovery. Given the project’s location within a prolific porphyry belt and close to the new Afton mine, this program represents an important step in unlocking the broader region-wide potential of Brussels Creek.
The New Afton Mine is described in the “Technical Report on the New Afton Mine, British Columbia, Canada” with an effective date of December 31, 2024. Proven and probable mineral reserves are reported to be approximately 830,000 ounces of gold, 2.3 million ounces of silver, and 631 million pounds of copper. Estimates are based on geological modeling, grade interpolation, and classification criteria supported by drilling data, and include assumptions regarding mineral prices, cut grades, mineral recoveries, and underground mining parameters.
Mineralization at the New Afton Mine is not necessarily indicative of mineralization at the Brussels Creek property.
Vanguard Mining also develops uranium exploration projects in the United States and Paraguay, with a focus on identifying and developing assets critical to the global energy transition.
