Banyan Gold Intersects 1.88 g/t Gold over 17.9 Metres in the Gap Between Airstrip and Powerline, and Identifies High-Grade Gold in Airstrip Footwall at AurMac, Yukon, Canada

VANCOUVER, BC / ACCESS Newswire / October 6, 2026 / Banyan Gold Corp. (the "Company" or "Banyan") (TSXV:BYN)(OTCQB:BYAGF) is pleased to report new results from the Airstrip Deposit ("Airstrip") and the gap between the Airstrip and Powerline Deposit at its AurMac Project ("AurMac"), Yukon, Canada. Drillhole AX-26-942 intersected 1.01 g/t gold ("Au") over 36.1 metres ("m") from 9.0 m downhole, including 1.88 g/t Au over 17.9 m from 27.2 m downhole and 28.70 g/t Au over 0.8 m, between the Airstrip and Powerline deposits. Mineralization is associated with large extensional quartz veins containing numerous grains of visible gold, with associated bismuth sulphosalts and sulphide mineralization. In Airstrip, drillholes AX-26-729 and -730 returned 1.19 g/t Au over 12.1 m and 6.79 g/t Au over 3.3 m, respectively. Mineralization in these holes is associated with replacement-style mineralization in calc-silicate altered horizons in the Airstrip footwall and lower Cal 2 horizon.

The results identify higher-grade, near-surface mineralization in the gap between Airstrip and Powerline and identify additional high-grade Airstrip horizons outside the current conceptual pit boundary. The drilling forms part of Banyan's ongoing work to improve confidence in the resource model, test higher-grade targets and resource expansion opportunities, and establish AurMac's development potential.

Highlights from Airstrip and North Powerline area:

AX-26-729 - 5.59 g/t Au over 2.0 m, within 1.19 g/t Au over 12.1 m; including 10.10 g/t Au over 0.9m

AX-26-730 - 6.79 g/t Au over 3.3 m, including 9.90 g/t Au over 1.0 m and 13.50 g/t Au over 0.8 m

AX-26-942 - 1.88 g/t Au over 17.9 m, within 1.01 g/t Au over 36.1 m

AX-26-897 - 0.96 g/t Au over 27.5 m, including 4.12 g/t Au over 5.1 m

AX-26-899 - 0.84 g/t Au over 5.4 m, and 5.76 g/t Au over 1.7 m

*Note: drillholes AX-26-729 and -730 were drilled in 2025 and analysed in 2026.

"The intersection of 1.88 g/t Au over 17.9 m in AX-26-942 highlights the potential for higher-grade near-surface mineralization in the largely undrilled gap between Airstrip and Powerline," stated Tara Christie, President and CEO. "The Airstrip footwall results identify additional higher-grade targets for follow-up. AurMac already has significant scale and our focus is on improving resource confidence and defining higher-grade areas that could contribute to a mine plan. Our first Preliminary Economic Assessment is targeted for completion in the fourth quarter of 2026 and will evaluate AurMac's economic potential. These results reinforce that exploration opportunities remain at AurMac, alongside the early discoveries at Nitra. Our strengthened treasury gives us the flexibility to pursue this work, with disciplined spending directed toward results and strategic milestones."

Drillholes reported in this release highlighted in blue, pending results are shown in green, previously released 2026 drilling is shown in orange, and all other diamond drilling pre-2026 in black. The reported holes have potential to extend higher-grade mineralized domains in the gap between the Airstrip and Powerline deposits and in the footwall of Airstrip. Detailed drillhole maps and sections are included below with a plan map of Airstrip (Figure 2) and cross-sections (Figures 3 to 5).

Figure 2: Plan map of Airstrip. Cross sections are denoted by blue lines (Figures 3 to 5). Cross section across the Airstrip Deposit at 467250mE (Figure 3) shows the potential for high-grade mineralization between the pits. Cross sections at 467400mE (Figure 4) and 467600mE (Figure 5) show potential for additional mineralized horizons in the footwall of Airstrip below the conceptual pit boundary.

Figure 3: Cross-section 467250mE through Airstrip and Powerline North at AurMac. Mineralized domains are overlaid on the lithological model. Hole AX-26-942 identifies a near-surface mineralized interval between the deposits; high-grade mineralization is hosted in extensional quartz veins with visible gold and associated bismuth sulphosalts and arsenopyrite (Figures 6 and 7). Mineralization remains open at depth. The interval in AX-26-942 highlights the potential to extend and identify new mineralized domains and upgrade domains on the margins of high-grade cores and between the Airstrip and Powerline Deposits. The Mineral Resource Estimate ("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.

Figure 4: Cross-section 467400mE through the eastern end of Airstrip at AurMac. Mineralized domains are overlaid on the lithological model. Mineralization remains open at depth, with new high-grade sulphide replacement horizons identified below Cal 2 in the footwall quartzite of Airstrip (Figure 9). These domains fall outside of the conceptual pit boundary and demonstrate the potential for resource expansion at 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.

Figure 5: Cross-section 467600mE through the eastern end of Airstrip at AurMac. Mineralized domains are overlaid on the lithological model. Mineralization in AX-26-730 confirms the extension of the Cal 2 horizon and potential to convert non-estimated blocks in the MRE with high-grade mineralization (Figure 10). 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.

Lithological domains at Powerline are dominated by metasedimentary rocks of various compositions, typically mica-chlorite schists with varying calcareous content. Domains shown in this section are: CLSR_4 and 5 - chlorite-sericite schist; CSCH_1 and 3 - calcareous schist; and sch_2 - heterogeneous schist. Altered host rocks with intense silicification and meta-greenstones are the preferential hosts for extensional quartz veining (Figures 6 and 7). Lithologic domains at Airstrip are dominated by calcareous metasedimentary rocks that readily undergo calc-silicate alteration and sulphide replacement mineralization (Figures 9 and 10). 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").

Figures 6 and 7: Mineralized extensional quartz veins in metasedimentary rocks of the Hyland Group from diamond drillhole AX-26-942 in Powerline North. Extensional quartz vein at 27.2 m - 28.0 m contains over 20 grains of visible gold spatially associated with bismuth sulphosalts and aggregates of arsenopyrite (Figure 8). Large (> 10 cm) extensional quartz veins are found throughout the interval from 9.0 m - 45.1 m, highlighting potential for well-mineralized zones near surface between the Airstrip and Powerline pits.

About Banyan

Banyan's primary asset, the AurMac Project, is located in the Traditional Territory of the First Nation of Na-Cho Nyäk Dun, in Canada's Yukon Territory. The AurMac Project comprises two main deposits, the Airstrip and Powerline Deposits. Mineralization is characteristic of a Reduced Intrusion Related Gold system, hosted in auriferous cross-cutting sheeted quartz veins and replacement-style mineralization hosted in skarn horizons. The current Mineral Resource Estimate ("MRE") for the AurMac Project has an effective date of May 15, 2026 and comprises an Indicated Mineral Resource of 3.639 million ounces of gold ("Au") (167.3 M tonnes at 0.68 g/t) and an Inferred Mineral Resource of 4.985 Moz of Au (267.2 M tonnes at 0.58 g/t) (See MRE Table 3 below; as defined in the 2014 CIM Definition Standards for Mineral Resources and Mineral Reserves incorporated by reference into NI 43â101). The 303 square kilometres ("sq km") AurMac Project lies 40 kilometres from Mayo, Yukon. The AurMac Project is transected by the main Yukon highway and benefits from a 69 kV 3-phase powerline, existing power substation and cell phone coverage.
