Banyan Gold intercepts 5.58 g/t Au over 21.7 m at Powerline deposit, AurMac project

VANCOUVER, BC / ACCESS Newswire / June 17, 2026 / Banyan Gold Corp . (the " Company " or " Banyan ") ( TSXV:BYN )( OTCQB:BYAGF ) is pleased to announce it has intersected high-grade gold (" Au ") mineralization in the Powerline Deposit (" Powerline ") southwest of the main high-grade core. These diamond drill intersections highlight a new potential high-grade zone at the AurMac Project (" AurMac "), Yukon, Canada. Highlights from New Powerline Southwest Zone : AX-26-853 - 13.00 g/t Au over 9.2m within 5.58 g/t Au over 21.7m , including high-grade interval of 62.66 g/t Au over 1.8m and; 1.64 g/t Au over 11.5m within 0.70 g/t Au over 32.2m AX-26-826 - 0.99 g/t Au over 9.4m within 0.65 g/t Au over 20.0m; including very high-grade interval of 17.30 g/t Au over 0.4m AX-26-829 - 2.51 g/t Au over 11.7m and 2.75 g/t Au over 9.3m within 0.90 g/t Au over 38.7m; including very high-grade interval of 39.80 g/t Au over 0.5m AX-26-830 - 0.70 g/t Au over 28.5m within 0.67 g/t Au over 56.8mm AX-26-835 - 1.29 g/t Au over 8.0m AX-26-842 - 0.96 g/t Au over 7.6m within 0.37 g/t Au over 33.9m "The successful step-outs from 2025 in the southwest portion of Powerline, have defined a new potential high-grade zone (Figures 1 and 2), highlighted with drill results of 13.00 g/t Au over 9.2m , within 5.58 g/t Au over 21.7m in hole AX-26-853, including 62.66 g/t over 1.8m (see Figure 3, Table 1)," stated Tara Christie, President and CEO.

"This very high-grade skarn-hosted mineralization (Figure 7) demonstrates the potential to discover and develop new mineralized zones at Powerline and AurMac in addition to high-grade domains associated with sheeted quartz veins (Figures 8 and 9). We are consistently intersecting visible gold as we are targeting high grade mineralized domains." Figure 1: Plan Map of AurMac show distribution of diamond drillholes. Magenta holes denote
