Banyan Gold Intersects 13.03 g/t Au over 14.2m at Powerline North, AurMac,

Drill Results

Yukon, Canada

August 17, 2026, TSX-V: BYN

VANCOUVER, BC, August 17, 2026 - Banyan Gold Corp. (the "Company" or "Banyan") (TSX-

V: BYN) (OTCQB: BYAGF) is pleased to announce it has intersected very high-grade gold (“Au”)

mineralization in the northern portion of the Powerline Deposit (“ Powerline”), highlighting the

potential to upgrade mineralized domains and expand the high -grade core of the Powerline

Deposit, AurMac Project (“AurMac”), Yukon, Canada. Drillhole AX-26-874 intersected 13.03 g/t

Au over 14.2 metres, including 142.70 g/t Au over 1.0 metre, extending high-grade mineralization

toward the largely undrilled gap between the Powerline and Airstrip Deposits (Figure 1). Much of

this area is currently classified as unmineralized in the Mineral Resource model. The results are

part of Banyan’s ongoing 2026 drill program at AurMac , focused on resource conversion,

expansion and delineation of higher-grade mineralized domains within and adjacent to the current

resource envelope.

Highlights from Powerline North:

AX-26-874 - 13.03 g/t Au over 14.2 metres (“m”), (true width 90% - 12.8m)

o including 18.10 g/t Au over 1.5m,

o 142.7 g/t Au over 1.0m,

o and 12.77 g/t Au over 1.2m; and,

o 0.80 g/t Au over 54.5 m including 6.39 g/t Au over 1.5m.

AX-26-832 – 1.17 g/t Au over 11.2m within 0.57 g/t Au over 26.1m

o including high-grade of 7.40 g/t Au over 1.0m

AX-26-840 – 1.86 g/t Au over 13.9m,

o including high-grade of 22.30 g/t Au over 1.0m; and,

o 0.42 g/t Au over 59.0m, including high-grade of 13.90 g/t Au over 0.5m

AX-26-871 – 1.42 g/t Au over 13.5m

o including high-grade of 16.03 g/t Au over 0.6m, 4.07 g/t Au over 0.4m and 9.81

g/t Au over 0.3m

“The 13.03 g/t Au over 14.2 metres intersected in AX-26-874 is an exceptional result, while its

location is equally important,” stated Tara Christie, President & CEO. “This intercept extends

high-grade mineralization into the largely undrilled gap between Powerline and Airstrip, an area

currently classified as unmineralized in the resource model. Our 2026 program is designed not

only to convert resources, but also to identify these higher-grade domains and demonstrate the

potential to increase both contained ounces and the overall grade profile at AurMac.”

The high-grade interval in AX-26-874 is characterized by a high density of extensional quartz

veins with bismuth sulphosalts, arsenopyrite and pyrite, together with multiple occurrences of

visible gold. The 142.70 g/t Au over 1.0 m interval is associated with a locally brecciated

extensional quartz vein containing coarse-grained to semi-massive arsenopyrite (Figure 5).

Figure 1: Plan map of AurMac, Yukon, Canada. Drillholes in this release highlighted in blue (Figure 2). Pending results

in green. All other diamond drilling is in black. The gaps between Airstrip and Powerline fall within the conceptual pit

boundary but remain largely undrilled except for the two fences of drilling in the centre and eastern end of the area.

Figure 1: Plan map of Powerline North. Drillholes in this release highlight the potential to extend and delineate new

high-grade zones in the core of Powerline (Figures 3 and 4). Drillholes AX-26-832, -840, -845, and -850 drill off angle

to test continuity of mineralization below the substation infrastructure.

Figure 3: Cross-section 467100mE from Powerline North at AurMac. Mineralized domains are overlaid on the

lithologic model. Mineralization remains open up-dip toward the largely undrilled gap between the Airstrip and

Powerline Deposits and at depth. The high-grade interval in AX-26-874 (Figure 5) highlights the potential to extend

mineralized domains beyond the current resource model and to identify additional mineralization within areas

currently estimated at low grade or as unmineralized within the conceptual pit shell. The MRE block model is

constrained by mineralized and lithologic domains. Mineral Resource blocks are 10m x 10m x 5m. 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.

Lithologic 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.

Figure 4: Cross-section 466900mE from Powerline North at AurMac. Mineralized domains are overlaid on the

lithologic model. Mineralized domains are open up-dip and at depth, with potential to expand the mineralized

envelope at depth. The MRE block model is constrained by mineralized domains and the lithologic domains. Mineral

Resource blocks are 10m x 10m x 5m. Only blocks above the 0.30 g/t Au cutoff and within the US$3,500/oz Au

conceptual pit shell are included in the MRE.

AX-26-874. High density of extensional quartz veins with bismuth-sulphosalts, arsenopyrite, and pyrite found

throughout the mineralized interval from 160.0-174.2m, which graded 13.03 g/t Au over 14.2m and hosts several

instances of visible gold mineralization (Figure 6). Locally, very high-grade gold intersection of 142.70 g/t Au over

1.0m is associated with locally brecciated quartz extensional vein with coarse-grained to semi-massive arsenopyrite.
