October 21, 2025 TSX-V: BYN
VANCOUVER, BC, October 21, 2025 - Banyan Gold Corp. (the "Company" or "Banyan") (TSX-
V: BYN) (OTCQB: BYAGF) is pleased to announce it has intersected high-grade gold at surface
in the core of the Powerline Deposit (“Powerline”) at its AurMac Project (“AurMac”) in the prolific
Tombstone Belt, Yukon, Canada.
Selected Highlights Demonstrate Continuity of High-Grade in Core of Central Powerline Deposit:
• AX-25-697 – 2.69 g/t gold (“Au”) over 11.8 metres (“m”) within 0.65 g/t gold over 72.5m;
including 29.3 g/t Au over 0.4m, 21.04 g/t Au over 0.4m, and 2.26 g/t Au over 3.4m.
• AX-25-700 – 3.07 g/t Au over 3.6m within 0.69 g/t Au over 29.3m, and 1.90 g/t Au over
17.3m; including 33.00 g/t Au over 0.8m
• AX-25-706 – 16.68 g/t Au over 1.1m within 2.39 g/t Au over 8.1m at surface
• AX-25-709B – 2.55 g/t Au over 6.4m within 0.85 g/t Au over 22.9m
High-grade gold in drillholes AX-25-697, 700, 706, and 709B, as outlined above, highlight the
potential for very high-grade gold intervals in Powerline and continue to reinforce continuity in the
core of the deposit and confirm new 3D modelling of the high-grade mineralized domains. These
intersections also have the potential to convert inferred ounces from the current Mineral Resource
Estimate (“MRE”) (Table 3) into indicated resources in the Powerline Deposit (Figure 1; Tables 1
and 2). To date, the Company has drilled over 30,000m (130 holes) on AurMac this year, with
current drill program ongoing.
“With our recent $31.4-million strategic investment by Alpayana we have upsized our drill program
to 40,000 m and have added a fourth drill rig,” stated Tara Christie, Banyan President and CEO.
“Our modelling and drilling suggests that the deposit is open in all directions, confirming the +1g/t
Au zones and potentially extending the zones beyond the previously known mineralization.”
“Our drilling in the core of Powerline (Figure 1) continues to confirm continuity of refined and high-
grade mineralized domains ,” added Duncan Mackay, Vice President of Exploration. “ With
mineralized domains open down-dip (Figure 2) we also have the potential to add additional high-
grade ounces while converting inferred ounces to indicated. We continue to intersect visible gold,
in zones of high-grade mineralization (Figures 3 and 4), and throughout the Powerline deposit.”

Figure 1: Plan map of the northeast portion of the Powerline Deposit. High-grade mineralization is associated with emplacement
of sheeted veins in favourable host rocks, primarily based on rheology ; more brittle rocks are favourable host s for sheeted vein
emplacement. Cross-section line for Figure 2 shown by gold line.
Sheeted-veins with visible gold, bismuth sulphosalts, and arsenopyrite are localized in higher
concentrations in zones of more competent, brittle rocks (Figures 3 and 4). Veins are centimetre
to decimetre in scale, generally with trace to 2% accessory minerals (bismuth sulphosalts and
arsenopyrite). As rheology of the stratigraphy controls vein emplacement, detailed modelling is
being carried out to refine the litho -structural model of the deposit and help define more refined
mineralized domains. Many mineralized domains are open down -dip, with potential for more
domains to be identified outside of the current mineralised envelope.

drillholes in this release reinforce continuity of high -grade mineralization. Down -drip extensions of mineralized domains have
potential to convert additional waste blocks into ore as well as flatten the conceptual pit floor.

Analytical Method and Quality Assurance/Quality Control Measures
All diamond drill core was systematically logged and photographed by Banyan geology
personnel. All core samples (HTW and NTW diameter) were split on -site at Banyan’s core
processing facilities. Once split, half samples were placed back in the core boxes w ith the other
half of split samples sealed in poly bags with one part of a three -part sample tag inserted
within. Samples were delivered by Banyan personnel or a dedicated expediter to the Bureau
Veritas, Whitehorse preparatory laboratory where samples are prepared and then shipped to
