Vanguard Mining completes Brussels Creek sampling

Executive Summary

• Vanguard Mining Corp. has completed its 2025 surface sampling program at the 100%-owned Brussels Creek gold-copper-palladium project in the Kamloops mining district, British Columbia.
• The program, conducted by Hardline Exploration Ltd., involved 21 rock samples and 127 soil samples to refine priority targets for future drilling based on a 2023 near-surface gold discovery.
• Analytical results are pending; upon receipt, Vanguard will prioritize targets for a potential 2026 drilling program and incorporate findings into a forthcoming NI 43-101 technical report.

Key Details

• Project Location: Brussels Creek project, Kamloops mining district, British Columbia, located approximately 24 km west of Kamloops and adjacent to New Gold’s New Afton mine.
• Program Scope:
  • Designed to follow up on a near-surface gold discovery reported in 2023.
  • Focused on systematic surface sampling to refine priority targets for follow-up drilling.
• Sampling Statistics:
  • 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 and extensions to known mineralized trends.
• Analytical Methods:
  • Rock Samples: Analyzed using a four-acid ICP package and fire assay for gold, platinum, and palladium.
  • Soil Samples: Analyzed using aqua regia digestion with fire assay for gold, platinum, and palladium where warranted.
  • Laboratory: SGS Canada Inc. in Burnaby, B.C.
• Quality Assurance/Quality Control (QA/QC):
  • Secure chain of custody maintained from collection through transport and laboratory submission.
  • Vanguard implements an internal QA/QC program including blanks, certified reference materials, and duplicate samples.
  • Qualified Person Lawrence Segerstrom, PGeo, MSc, MBA, reports no issues with sampling, analytical procedures, or data integrity.
• Future Plans:
  • Results will be used to prioritize targets for a potential 2026 drilling program.
  • Results will be incorporated into the forthcoming National Instrument 43-101 technical report.
• Regional Context:
  • The release highlights the strategic importance of the region following Coeur Mining Inc.'s announcement on Nov. 3, 2025, to acquire New Gold Inc. in a $7-billion (U.S.) all-stock transaction.
  • Brussels Creek is situated in the Quesnel terrane, known for large alkalic porphyry copper-gold systems.
• Indigenous Relations:
  • Project lies within the Stk'emlupsemc te Secwepemc territory.
  • Vanguard is engaged in consultation and an archaeological impact assessment (AIA) required prior to accessing additional priority sites.

Notable Quotes

• David Greenway, President and CEO of Vanguard Mining: "The 2025 surface program at Brussels Creek represents an important step in advancing our understanding of the broader mineralized system. The near-surface gold intercept reported in 2023 provided a strong proof-of-concept, and this year's detailed rock and soil sampling is designed to refine the vectors toward additional drill targets. These results will also contribute directly to advancing a new NI 43-101 technical report for the project. We look forward to reviewing the assay data as we continue to systematically advance this promising gold-copper-palladium project."
