Vanguard Mining orders Brussels NI 43-101 report

Executive Summary

• Vanguard Mining Corp. has retained Hardline Exploration Ltd. to prepare an updated National Instrument 43-101 technical report for its 100%-owned Brussels Creek gold-copper-palladium project in British Columbia.
• The company recently completed a surface sampling program (announced June 10, 2025) comprising 21 rock samples and 127 soil samples to refine geological vectors and identify drill targets.
• The updated NI 43-101 report is expected to be completed before the end of January 2026, following the receipt and review of pending assay results from the 2025 sampling program.

Key Details

• Technical Report Engagement: Hardline Exploration Ltd. retained to complete the NI 43-101 technical report.
• Sampling Program Details (2025):
  • Rock Samples: 21 samples collected from surface mineralized zones, structural features, and altered host rocks.
  • Soil Samples: 127 samples collected in systematic grids to define geochemical anomalies.
  • Laboratory: SGS Canada Inc. (Burnaby, B.C.).
  • Analytical Methods:
    • Rock samples: Four-acid ICP package and fire assay for gold, platinum, and palladium.
    • Soil samples: Aqua regia digestion with fire assay for gold, platinum, and palladium where warranted.
• Historical Context: The 2025 program follows up on a 2023 near-surface drill intercept of 5.08 grams per tonne gold from 25.75 metres to 29.25 metres (3.5 metres).
• Project Location: Brussels Creek project, Kamloops mining district, British Columbia, adjacent to New Gold's New Afton mine.
• Strategic Context: Coeur Mining Inc. announced a definitive agreement to acquire New Gold Inc. in a $7-billion (U.S.) all-stock transaction, elevating the strategic importance of the region.
• Indigenous Collaboration: Vanguard is working with the Tk'emlups te Secwepemc Nation, focusing on local employment, training, and environmental stewardment. An archaeological impact assessment (AIA) is ongoing.
• Qualified Person: Lawrence Segerstrom, PGeo, MSC, MBA (consulting geologist, not at arm's length).

Notable Quotes

• David Greenway, President and CEO: "The near-surface gold intercept reported in 2023 delivered a compelling proof-of-concept for the Brussels Creek project. Our recent rock and soil sampling program is focused on refining geological vectors and identifying additional high-priority drill targets within this gold-copper-palladium system. The results will directly support the advancement of an updated NI 43-101 technical report, representing an important step in derisking and systematically advancing this highly prospective project."
