Au and Extends Mineralization Between Deposits, AurMac Project,

VANCOUVER, BC, September 4, 2025 - Banyan Gold Corp . (the " Company" or "Banyan")
(TSX-V: BYN) (OTCQB: BYAGF) is pleased to announce it has intersected 104.4 metres (“m”)
at 0.82 g/t Au including 33.2m at 1.44 g/t Au and 3.1m at 5.8 g/t Au in drillhole AX-25-678 at
the southern extent of the Airstrip Deposit (“ Airstrip”) at its AurMac Project (“AurMac”) in the
prolific Tombstone Belt, Yukon, Canada. This drillhole highlights the potential for Airstrip
mineralization to extend below Powerline and bridge the gap between the conceptual pits. In
addition, drill results indicate potential extensions to the mineralized envelope at Airstrip, east and
southeast of the Mineral Resource Estimate (“MRE”) (Table 3) conceptual pit, as well as a step
out east of Airstrip demonstrates near-/at-surface high-grade mineralization (Figure 1). To date ,
over 27,000m (120 holes) have been drilled by the Company this year on the Aur Mac Project,
with drilling currently ongoing.
Selected Highlights:
• AX-25-678 – 104.4 m at 0.82 g/t Au including 33.2m at 1.44 g/t Au and 3.1m at 5.8 g/t
Au
• AX-25-659 – 11.5m at 1.53 g/t Au
• AX-25-665 – 8.5m at 0.81 g/t Au including 4.2m at 1.29 g/t Au
• AX-25-670 – 29.1m at 1.04 g/t Au including 6.7m at 3.90 g.t Au
• AX-25-672 – 18.0m at 1.11 g/t Au including 3.8m at 4.31 g/t Au
• AX-25-674 – 16.0m at 1.15 g/t Au including 4.8m at 3.43 g/t Au
“These results continue to define higher grade zones ( +1 g/t material) at AurMac,” stated Tara
Christie, President and CEO. “While visible Gold is frequent in Powerline deposit style
mineralization, t he presence of visible gold in sheeted veins in close association with skarn
mineralization in drillhole AX-25-678 at Airstrip highlights the continued potential for high -grade
mineralization throughout the system. After intersecting some of the most enriched mineralization
at Airstrip to date, AX-25-650 intersected 3.95 g/t Au over 38.1m (see News Release dated June
25, 2025), we continue to trace high -grade near-surface mineralization along strike and up -dip.
Today’s drill results highlight the potential to expand the footprint of Airstrip mineralization East
and West, and also down dip and between the two deposits at AurMac.”
Duncan Mackay, Vice President of Exploration, continued, “Step-out drilling at Airstrip continues
to confirm the strength and continuity of mineralization as we test the limits of the system. Drillhole
AX-25-659, collared northeast of Airstrip, intersected a new zone of at-surface mineralization
including 4.0m at 3.16 g/t Au . This result demonstrates that mineralization remains open and
indicates potential for further extension of this new zone down dip and along strike . The high-
grade skarn mineralization in AX-25-678 ( as well as AX-25-670, AX-25-672, and AX-25-674) with
2
individual samples of 0.6m at 11.3 g/t Au, 0.3m at 24.8 g/t Au, and 0.4m at 22.5 g/t Au shows
the potential for very high -grade skarn mineralization in Airstrip, 250m down dip of the dyke
contact and a little below the conceptual pit floor (Figure 2).”
Figure 1: Plan map of the Airstrip and Northern Powerline deposits. Follow -up on drill step outs east of Airstrip (AX -25-659 and
665) have identified potential along strike continuation of the deposit and possible expansion of the mineralized envelope up to
300m east. Up-dip and eastward step outs in drillholes AX-25-670 and 672 extend high skarn-grade mineralization outside of the
conceptual MRE pit and remain open up-dip. Follow-up on the inter-pit fence in 2024 (location of Section 1 – Figure 2) indicates
potential to expand Airstrip mineralization south and further link the two pits; a similar fence at the east of Airstrip also indicates
potential to connect the pits.

Figure 2: 50m Cross Section - 466825mE. Intersection in AX -25-678 extends mineralization down dip at Airstrip. AX -25-661 and
AX-25-674 intersect Powerline -style mineralization near surface and extend Airstrip mineralization at depth, with potential to
further link pits.

Figure 3: Cross-section at 467525mE. Drill holes AX -25-670 and AX-25-672 intersect skarn-style mineralization with potential to
extend mineralization envelope further up -dip. Drill holes AX -25-682 and AX-25-676 likely extend Airstrip mineralization south
with potential to link the two pits.
High-grade gold mineralization in AX-25-678 (with multiple visible gold occurrences , Figure 4)
includes intense calc-silicate skarn mineralization typical of Airstrip (Figure 5) as well as intense
sheet vein development in the footwall quartzite (Figure 6). The high-grade mineralization,
104.4m at 0.82 g/t Au including 30.9m at 1.44 g/t Au (Table 1) , is highlighted by internal
intervals such as 7.2m at 3.17 g/t Au with 0.6m at 11.3 g/t Au and 0.3m at 24.8 g/t Au and 9.2m
at 3.59 g/t Au, further demonstrating the pervasive alteration and mineralization at Airstrip.

678. Visible gold intersected at 296.3m. High-grade mineralization stratigraphically below typical “Airstrip -style” mineralization
reinforces the potential for expansion at Airstrip and across the deposit.
