Nov 13, 2025, TSX-V: BYN

VANCOUVER, BC, Nov 13, 2025 - Banyan Gold Corp. (the "Company" or "Banyan") (TSX-V:

BYN) (OTCQB: BYAGF) continues to intersect high-grade mineralization in Airstrip (“Airstrip”)

and extend the high-grade domains at its AurMac Project (“AurMac”).

Drill-hole highlights include:

• AX-25-708 – 3.66 g/t Au over 17.6 metres (“m”), including 6.80 g/t Au over 9.3m, with

high-grade interval of 35.98 g/t Au over 1.6m

• AX-25-640 – 1.25 g/t Au over 5.4m within 0.72 g/t Au over 13.0m

• AX-25-703 – 2.04 g/t Au over 11.4m, including 3.60 g/t Au over 5.6m with a high-grade

interval of 7.98 g/t Au over 1.2m

• AX-25-711 – 1.25 g/t Au over 7.00m

• AX-25-712 – 1.36 g/t Au over 15.3m including 1.87 g/t Au over 9.1m

• AX-25-714 – 1.12 g/t Au over 18.4m including 2.12 g/t Au over 6.7m and 1.49 g/t Au over

4.6m

“These results continue to highlight the >1g/t Au near-surface mineralized domains in AurMac,”

said Tara Christie, Banyan President and CEO.

“We continue to see strong replacement (skarn) style mineralization at Airstrip in the lower

calcareous metasedimentary unit that contacts the felsic dyke (Cal 2) that was intersected in hole

AX-25-650 (see News Release dated June 25, 2025),” stated Duncan Mackay, Vice President of

Exploration. “Extending very high -grade mineralization over 100m down dip with an interval of

35.98 g/t Au over 1.6m ( calculated true thickness is approx. 1.5m) highlights the potential to

continue to add ounces to the Airstrip deposit and improve areas of the existing Mineral Resource

Estimate. The high-grade core of Airstrip associated with the felsic dyke contact now extends over

500m along strike and nearly 300m down dip.”

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 were analysed by Bureau Veritas of Vancouver, B.C.,

utilizing the four-acid digestion ICP -ES 35-element MA-300 or ICP -ES/MS 59-element MA-250

analytical package with FA -450 50 -gram Fire Assay with AAS finish for go ld on all

samples. Samples returning >10 g/t Au were reanalysed by fire assay with gravimetric finish on a

8

50g sample (FA-550). High-grade samples with documented visible gold are also analysed using

metallic screen fire assay (FS -652). Bureau Veritas is an accredited lab following ISO/IEC

17025:2017 SCC File Number 15895. A robust system of standards, ¼ core duplicates and blanks

has been implemented in the 2025 exploration drilling program and is monitored as chemical

assay data becomes available.

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 a nd 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.
