Banyan Extends Mineralization into the Airstrip–Powerline Gap at AurMac, Yukon, Intersects 1.34 g/t Au over 20.2 metres and 1.18 g/t Au over 27.5 metres

VANCOUVER, BC / ACCESS Newswire / October 28, 2026 / Banyan Gold Corp. (the "Company" or "Banyan") (TSX-V:BYN)(OTCQB:BYAGF) is pleased to report results from six drillholes from the Airstrip Deposit ("Airstrip") at its AurMac Project ("AurMac"), Yukon, Canada (Table 1). Drillhole AX-26-921 intersected high-grade gold ("Au") in four discrete zones: 0.85 g/t Au over 28.9 metres ("m"), 1.34 g/t Au over 20.2 m, 1.89 g/t Au over 10.1 m, and 1.18 g/t Au over 27.5 m. These intersections highlight extensions of domains within the mineralized gap between the Airstrip and Powerline Deposits; mineralization is hosted in sulphide replacement of carbonaceous metasedimentary rocks down-dip of the main Airstrip domains. Other drillholes in this release (AX-26-904, -908, -909, -913 and -915) highlight extensions to higher-grade zones in central Airstrip.

Highlights from Airstrip:

• AX-26-904 - 0.79 g/t Au over 14.1 m, including 25.70 g/t Au over 0.3 m
• AX-26-908 - 7.11 g/t Au over 1.3 m within 0.62 g/t Au over 18.5 m
  • AND 2.97 g/t Au over 3.7 m
• AX-26-909 - 0.69 g/t Au over 23.3 m
• AX-26-913 - 0.82 g/t Au over 7.3 m
• AX-26-915 - 0.96 g/t Au over 39.6 m
• AX-26-921 - 0.85 g/t Au over 28.9 m, including 12.44 g/t Au over 1.2 m;
  • AND 1.34 g/t Au over 20.2 m; including 15.40 g/t Au over 0.6 m;
  • AND 1.89 g/t Au over 10.1 m, including 12.10 g/t Au over 0.8 m;
  • AND 1.18 g/t Au over 27.5 m, including 16.50 g/t Au over 1.4 m

Note: All highlighted intervals are downhole lengths; approximate calculated true widths are expressed as percentages of downhole interval lengths (see Table 2).

"This year's program aims to pinpoint areas with high-grade mineralization, particularly where the current resource model shows unmineralized regions. Drillhole AX-26-921 produced significant high-grade intersections that suggest potential for expansion and improved grades between the Airstrip and Powerline Deposits," stated Tara Christie, President and CEO. "Specifically, AX-26-921 returned several mineralized intervals, including 1.34 g/t Au over 20.2 m and 1.18 g/t Au over 27.5 m, indicating continuity of the higher-grade zones at depth in the Airstrip deposit below the gap. These results reinforce that expansion opportunities remain at AurMac, alongside the early discoveries at Nitra. Banyan's next exploration phase will focus on identifying the prime areas within AurMac that will contribute to our initial 10-year grade and production profile, leading to further studies beyond our Preliminary Economic Assessment."

Figure 1: Plan map of AurMac, Yukon, Canada. Results for drillholes AX-26-904, -908, -909, -913, -915 and -921 are reported in Table 1. A plan map of Airstrip (Figure 2) and cross-sections (Figures 3 and 4) show the detailed distribution of drillholes in Airstrip and the geometry of high-grade mineralization.

Figure 2: Plan map of Airstrip. Cross-sections are denoted by blue lines. Drillhole AX-26-921 in cross-section 466900mE (Figure 3) highlights the expansion potential for high-grade domains in the gap between the Airstrip and Powerline Deposits near the southern extent of the conceptual Mineral Resource Estimate ("MRE") pit. Drillholes AX-26-904, -908, -909, and -915 in cross-section 467300mE (Figure 4) highlight the expansion potential for high-grade domains to the east in Airstrip.

Mineralization at Airstrip is predominantly hosted in calcareous metasedimentary rocks that readily undergo calc-silicate alteration and sulphide replacement mineralization (Figure 5). Calcareous metasedimentary rocks overlie quartzites. Domains Cal_1 and Cal_2 (calcareous metasedimentary rocks) are the primary host for gold mineralization at Airstrip, with extensional quartz veins hosted in the quartzite ("QTZT"). A notable zone of mineralization has been intersected in the footwall of Airstrip, with high-grade mineralization and visible gold (Figure 6) identified in extensional quartz veins hosted in quartzite stratigraphically below the main Airstrip deposit (Figure 3). Potential for footwall domains in the Airstrip area has been identified in previous drilling and is being tested this drill season.

Figure 3: Cross-section 466900mE through Airstrip. Drillhole AX-26-921 highlights potential expansion of high-grade domains in the gap zone between Airstrip and Powerline. Additional down-dip drilling is planned to further test the extent of high-grade mineralization at depth within and just south of the conceptual pit boundary. The MRE block model is constrained by mineralized and lithological domains. Mineral Resource blocks are 10 m x 10 m x 5 m. Only blocks above the 0.30 g/t Au cut-off and within the US$3,500/oz Au conceptual pit shell are included in the MRE.

Drillholes in this release demonstrate potential for improvement in grade in mineralized domains in the eastern end of Airstrip. The MRE block model is constrained by mineralized and lithological domains. Mineral Resource blocks are 10 m x 10 m x 5 m. Only blocks above the 0.30 g/t Au cut-off and within the US$3,500/oz Au conceptual pit shell are included in the MRE.
