Banyan Gold Continues to Extend Powerline Mineralization Beyond

Existing Resource and Between Deposits, AurMac, Yukon, Canada

Dec 9, 2025, TSX-V: BYN

VANCOUVER, BC, Dec 9, 2025 - Banyan Gold Corp. (the "Company" or "Banyan") (TSX-V:

BYN) (OTCQB: BYAGF) continues to expand and upgrade the Powerline Deposit (“Powerline”)

at its AurMac Project (“AurMac”), First Nation of Na-Cho Nyäk Dun Traditional Territory, Yukon.

The diamond drillholes reported here intersected new high-grade domains extending Powerline

mineralization to a new area southwest of the main deposit and demonstrating the continuity of

high-grade in the central Powerline deposit and between the Airstrip Deposit.

Highlights:

• AX-25-690 – 1.15 g/t Au over 10.5m within 0.74 g/t Au over 45.5m, including high-grade

intervals of 6.82 g/t Au over 1.9m and 9.75 g/t Au over 1.0m

• AX-25-694 – 4.27 g/t Au over 2.0m within 0.62 g/t Au over 28.6m

• AX-25-724 – 4.60 g/t Au over 5.9m within 0.64 g/t Au over 55.4m; including high-grade

interval of 14.90 g/t Au over 1.5m

• AX-25-728 – 0.86 g/t au over 16.5m and 1.03 g/t au over 6.8m

• AX-25-741 – 1.97 g/t Au over 3.3m within 0.29 g/t Au over 78.2m

• AX-25-746 – 1.70 g/t Au over 5.7 m within 0.92 g/t Au over 18.8 m

• AX-25-748 – 3.41 g/t Au over 0.5m and 0.65 g/t Au over 12.2m within 0.30 g/t Au over

89.1m

Banyan Gold has completed its 2025 drilling program with 178 holes over 42,700 m completed;

with the last core shipped to the assay lab from camp last week. Thank you to our team, service

providers, suppliers, consultants, and partners for a productive year.

“We have successfully intersected high-grade intervals at the Resource pit edge with additional

sheeted veins hosting coarse sulphosalts, sulphides and visible gold in follow-up step outs 100

and 400 m from know n mineralisation, with assay results pending (holes AX-25-772 and -779

respectively, Figure 5),” said Tara Christie, Banyan President and CEO. “ Our new geologically

supported mineralisation model continues to provide opportunities to upgrade portions of our

deposit by converting waste blocks to high-grade ore, reducing strip ratios within the conceptual

pit and by expanding the mineralized envelope to add ounces.”

Powerline, additional step outs with assays pending denoted by green dots. Note section lines for 466750E and 466800E.

Continued drilling at Powerline has successfully confirmed mineralized domains in the core of

Powerline (Figure 3), refined and extended mineralization between the Powerline and Airstrip

main pits (Figure 2) and extended mineralization with potential to convert waste blocks in the

southwest of Powerline (Figure 5).

Figure 2: Intersections reported in this news release, AX -25-688, -690, -692, further define the geologically based mineralized

domains (magenta ellipses) and results demonstrate potential for extension along strike and down dip.

Figure 3: High-grade mineralization in zones from AX-25-719, -728, -724, -732 support continuity of mineral domains in the core

of Powerline. Mineralized domains are open to depth with potential for further down dip extension.

Gold mineralization in southwest Powerline is consistent with mineralization seen in the core of

Powerline; gold mineralization is associated with discordant sheeted quartz veins hosting

sulphosalts and sulphides (predominantly sphalerite, arsenopyrite) ( Figure 3) which is

preferentially hosted in silicified/altered host rocks.

units).

Figure 5: Cross-section of the Powerline Deposit looking at AZM 135. Potential mineralized domain (in magenta) intersected in

the drillholes in this release and show potential for down -dip extension, waste block conversion, and expansion of mineralized

envelope to step out drillholes. Drillhole AX-25-779 (100m south, assays pending) intersected coarse sulphosalts and sphalerite

in discordant quartz veins hosting visible gold (Figure 3). Results are also pending from a 400 m step out drillhole AX-25-772 that

intersected similar Bi-Sb sulphosalt bearing discordant quartz veins.

Figure 6: Mineralized interval from drillhole AX-25-746. High vein density, Bi-Sb sulphosalts and visible gold are indicative of

high-grade mineralization, confirmed by assay results.
