Banyan Gold - Silver Discovery with New Drilling Confirming the

2021 Results of 1841.14 g/t Ag over 16.8m at AurMac, Yukon, Canada

October 29, 2025, TSX-V: BYN

VANCOUVER, BC, October 29, 2025 - Banyan Gold Corp. (the "Company" or "Banyan") (TSX-

V: BYN) (OTCQB: BYAGF) is pleased to announce it has intersected visible silver mineralization

in the current drill program. This confirms the high-grade silver (“Ag”) first drilled in 2021, near

surface in the core of the Powerline Deposit (“ Powerline”) at its AurMac Project (“AurMac”) in

the prolific Tombstone Belt, Yukon, Canada.

Selected Highlights Demonstrate Potential for High -Grade Silver Zone s in Core of Central

Powerline:

• AX-21-142 – 1841.14 g/t Ag over 16.8 metres (“m”) within 302.68 g/t Ag over 103.6 m;

includes 14,629 g/t Ag over 1.1m and 11,828 g/t Ag over 1.2m

• AX-21-143 – 12.85 g/t Ag over 19.0m, and 20.03 g/t Ag over 4.9m, and 20.22 g/t Ag over

30.5m, within 7.93 g/t Ag over 162.3m

• AX-21-161 – 13.10 g/t Ag over 12.5m within 10.38 g/t Ag over 18.6m

• AX-24-542 – 4.29 g/t Ag over 7.9m, and 11.22 g/t Ag over 18.9m, and 44.69 g/t Ag over

2.1m

“We have long recognized the potential for Keno -style silver mineralization at AurMac. It is an

exciting time to follow -up on these intersections from our 2021 drilling and test the potential for

larger silver zones ,” said Tara Christie, Banyan President and CEO. “ Drilling at Powerline will

further define our gold deposit and at the same time also test to identify favourable structures that

host high-grade silver mineralization at AurMac.”

“Our drilling in the core of Powerline previously intersected discrete veins hosting high-grade silver

mineralization (Figures 1 and 2) in Fe -carbonate, sphalerite, galena and instances of visible

electrum (Figures 3 and 4),” stated Duncan Mackay, Vice President of Exploration. “ Leveraging

our database of oriented core, we are working to refine these high-grade silver targets by drilling

to confirm the orientation of the mineralized structures . Preliminary testing has successfully

intersected the high-grade vein (assays pending), with additional drillholes planned to further test

this highly prospective zone (Figure 5). The potential to identify new phases of mineralization of

significance at AurMac adds a new dynamic to the project and understanding of the interlinkage

between the Intrusion related Powerline Gold Mineralisation and the High -Grade Keno Style

mineralization.”

Figure 1: Plan map of the central Powerline Deposit (g*m Au heat map above illustrates spatial association with Powerline Au

mineralization). High-grade Silver mineralization is associated with steeply north-dipping, northeast to southwest oriented

structures (approximate trace in magenta). Cross-section line for Figure 2 shown by white line.

Silver mineralization is associated with crosscutting, steeply dipping Fe-carbonate veins hosting

coarse aggregates of sphalerite and galena with instances of fine -grained electrum (Figures 3

and 4). High-grade silver mineralization is discrete from gold domains at Aurmac . With active

silver mining in the area, zones of high-grade silver have potential as a selectively mined product.

Figure 2: Cross-section of the Powerline Deposit at looking at 060. Potential mineralized domain for high-grade silver intersections

(in magenta) intersected in the drillholes in this release and show potential for down -dip extension. Drillhole AX -25-803 (blue

trace; assays pending) successfully intersected the high -grade Keno-style vein (Figure 5). Additional drill testing will help refine

understanding of mineralized domain/vein orientation.

Figure 3: Electrum (right) associated with coarse aggregates of sphalerite and galena in Fe-carbonate veins from drillhole AX-21-

142 at approx. 107.85m.

Figure 5: High-grade Keno-style mineralization intersected in drillhole AX -25-803 from 116-118.7m. Mineralization consists of

coarse-grained, semi-massive sphalerite, galena, pyrite, chalcopyrite, with minor Ag-Sb sulphosalts (pyrargyrite) and tetrahedrite.

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

Bureau Veritas’s Analytical laboratory in Vancouver, B.C. for pulverization and final chemical

analysis.

Core splits reported in this news release for 2021 were analysed by SGS Canada of Burnaby,

B.C., utilizing the aqua -regia digest ICP -MS (HCL/HNO3) 36 -element GE_IMS21B20 with

GE_FAA30V5 30-gram Fire Assay with AAS finish for gold on all samples. Samples returning >10

g/t Ag were reanalysed by aqua -regia digest ICP -AES GE_ICP21B20. If Ag samples were

expected to run ore -grade they were analyzed by GC_FAG32V, 30 -gram Fire Assay with AAS

finish for gold and silver samples. Samples for 2024 reported here were a nalysed by Bureau

Veritas’s Analytical laboratory in Vancouver, B.C utilizing the MA300, 35-element ICP analytical

package in conjunction with the FA450 50-gram Fire Assay with Gravimetric finish for gold on all

samples.

About Banyan

Banyan's primary asset, the AurMac Project is located in the Traditional Territory of First Nation

of Na -Cho Nyäk Dun, in Canada’s Yukon Territory. The current Mineral Resource Estimate

(“MRE”) for the AurMac Project has an effective date of June 28, 2025 and comprises an Indicated

Mineral Resource of 2.274 million ounces of gold (" Au") (112.5 M tonnes at 0.63 g/t) and an

Inferred Mineral Resource of 5.453 Moz of Au (280.6 M tonnes at 0.60 g/t ) (as defined in the

Canadian Institute of Mining, Metallurgy and Petroleum (" CIM") Definition Standards for Mineral

Resources & Mineral Reserves incorporated by reference into NI 43 -101). The 303 square

kilometres (“sq km”) AurMac Project lies 40 k ilometres from Mayo, Yukon. The AurMac Project

is transected by the main Yukon highway and benefits from a 3-phase powerline, existing power

station and cell phone coverage.

Notes to Table 3:

1. The effective date for the MRE is June 28, 2025, and was prepared by Marc Jutras, P.Eng., M.A.Sc., Principal,

Ginto Consulting Inc., an independent "Qualified Person" within the meaning of NI 43-101.

2. Mineral Resources, which are not Mineral Reserves, do not have demonstrated economic viability. The

estimate of Mineral Resources may be materially affected by environmental, permitting, legal, title, taxation,

sociopolitical, marketing, changes in global gold markets or other relevant issues.

3. The CIM Definition Standards were followed for classification of Mineral Resources. The quantity and grade

of reported Inferred Mineral Resources in this estimation are uncertain in nature and there has been insufficient

exploration to define these Inferred Mineral Resources as an Indicated Mineral Resource.

4. Mineral Resources are reported at a cut-off grade of 0.30 g/t gold for all deposits, using a US$/CAN$ exchange

rate of 0.73 and constrained within an open pit shell optimized with the Lerchs -Grossman algorithm to

constrain the Mineral Resources with the following estimated parameters: gold price of US $2,050/ounce,

US$2.50/t mining cost, US$10.00/t processing cost, US$2.00/t G+A, 90% gold recoveries, and 45° pit slopes.1

5. The number of tonnes and ounces was rounded to the nearest thousand. Any discrepancies in the totals are

due to rounding effects.

In addition to the AurMac Project, the Company holds the Hyland Gold Project, located 70 km

Northeast of Watson Lake, Yukon, along the Southeast end of the Tintina Gold Belt (the “Hyland

Project”) in the Traditional Territory of the Kaska Nations, closest to the Liard First Nation and

Daylu Dena Council. The Hyland Project represents a sediment hosted, structurally controlled,

intrusion related gold deposit, within a large land package (over 125 sq km), accessible by a

network of existing gravel access roads. The updated MRE comprises an Indicated Mineral

Resource of 337 thousand (“k”) ounces (“oz”) of gold (“Au”) and 2.63 million (“M”) oz of silver

(“Ag”) (11.3 M tonnes of ore at 0.93 g/t Au and 7.27 g/t Ag), and an Inferred Mineral Resource of

118 koz of Au and 0.86 Moz Ag (3.9 M tonnes of ore at 0.95 g/t Au and 6.94 g/t Ag) (as defined

in the Canadian Institute of Mining, Metallurgy and Petroleum (“ CIM”) Definition Standards for

Mineral Resources & Mineral Reserves incorporated by reference into NI 43-101) effective

September 1, 2025 and with technical report filed on Sedar on October 27, 2025.

Banyan also holds the Nitra Gold Project, a grassroots exploration project located in the Mayo

Mining district, approximately 10 km west of the AurMac Gold property. The Nitra Property lies in

the northern part of the Selwyn basin and is underlain by metaclastic rocks of the Late Proterozoic

Yusezyu Formation of the Hyland Group, similar to lithologies hosting portions of the AurMac

Project. Middle Cretaceous Tombstone Plutonic suite intrusions occur along the property

including the Morrison Creek and Minto Creek stocks. The property is 100% owned and operated

by Banyan Gold Corporation ("Banyan") and covers approximately 313.9 sq km. The property is

accessible by road along the Silver Trail Highway, South McQuesten Road and 4x4 roads.

Banyan trades on the TSX -Venture Exchange under the symbol “ BYN” and is quoted on the

OTCQB Venture Market under the symbol “ BYAGF”. For more information, please visit the
