Banyan Gold Intersects 10,734 g/t Silver Over 1.7m, Confirming Structure Hosting High Grade Keno-Style Mineralization, AurMac, Yukon, Canada

Executive Summary

• Banyan Gold Corp. announced high-grade silver intercepts from its 2025 drilling program at the Powerline Deposit within the AurMac Project in Yukon, Canada.
• The results confirm the continuity of the high-grade Ag-1 vein structure, intersecting significant intervals of silver mineralization near previous historic high-grade zones.
• Hole AX-25-803 returned a standout interval of 10,734 g/t Ag over 1.7m, reinforcing the potential for Keno-style silver mineralization and parallel vein structures (Ag-2 and Ag-3).

Key Details

• Hole AX-25-803:
  • 5,625 g/t Ag over 3.4m within 1,841 g/t Ag over 10.4m.
  • High-grade interval: 10,734 g/t Ag over 1.7m.
  • Drilled 90m away from historic hole AX-21-142; intersected the vein 20m from hole 142 at a depth of 115m.
• Hole AX-25-790:
  • 110.7 g/t Ag over 0.8m within 22.06 g/t Ag over 5.7m.
• Hole AX-25-715:
  • 132 g/t Ag over 0.5m within 7.25 g/t Ag over 13.7m.
• Historical Context (AX-21-142):
  • Previously reported 1,841.14 g/t Ag over 16.8m within 302.68 g/t Ag over 103.6m.
  • Included intervals of 14,629 g/t Ag over 1.1m and 11,828 g/t Ag over 1.2m.
• Geological Interpretation:
  • High-grade silver veins overprint gold mineralization, representing a new target.
  • Veins exploit steeply dipping, late brittle structures striking northeast-southwest, distinct from the sheeted veins hosting gold.
  • Sub-parallel veins (Ag-2 and Ag-3) identified adjacent to Ag-1; further testing planned to confirm orientation and continuity.
  • Mineralization is open along strike to the northeast and down-plunge.
• Mineral Resource Estimates (AurMac Project - Effective June 28, 2025):
  • Indicated: 2.274 Moz Au (112.5 M tonnes at 0.63 g/t).
  • Inferred: 5.453 Moz Au (280.6 M tonnes at 0.60 g/t).
  • Hyland Project (Effective Sept 1, 2025): Indicated 337 Koz Au / 2.63 Moz Ag; Inferred 118 Koz Au / 0.86 Moz Ag.
• Upcoming Events:
  • Metals Investor Forum Vancouver (Jan 23-24).
  • AME Roundup, Vancouver (Jan 28-29).
  • Money Talks: World Outlook Financial Conference, Vancouver (Feb 6-7).
  • 121 Mining Investment, Cape Town (Feb 9-10).
  • African Mining Indaba, Cape Town (Feb 9-12).
  • BMO 35rd Global Metals, Mining & Critical Minerals Conference, Hollywood, FL (Feb 22-25).

Notable Quotes

• "The high-grade Keno-style veins overprinting the gold mineralization represent a compelling new potential target for Banyan... Being able to successfully target this specific narrow, high-grade vein structure at depth is a technical success on top of the prospectivity for additional veins of silver mineralization we are finding in the Ag-1 vein zone." — Tara Christie, President and CEO
• "These high-grade silver results from hole AX-25-803 confirm continuity of the Ag-1 vein in central Powerline... The high-grade veins take advantage of different, steeply dipping, late brittle structures... We are working to determine the extent and potential for repetition of the thicker high-grade veins we see in holes AX-21-142 and AX-25-803 and improve targeting of silver mineralization across the deposit." — Duncan Mackay, Vice President Exploration
