Banyan Gold Intersects 3.66 g/t over 17.6 m Continuing to Extend High-Grade Mineralization in Airstrip Deposit, AurMac Project, Yukon, Canada

Rhea-AI Summary

Banyan Gold (OTCQB:BYAGF) reported November 13, 2025 drill results from the AurMac Airstrip deposit with multiple near-surface intercepts, including 3.66 g/t Au over 17.6 m (AX-25-708) and a very high-grade core interval of 35.98 g/t Au over 1.6 m. Company exploration extends the high-grade core to ~500 m strike and ~300 m down dip. The release reiterates the June 28, 2025 pit-constrained MRE of 2.274 Moz indicated and 5.453 Moz inferred Au across AurMac. 230,000 incentive stock options were granted at $0.91 with up to 18-month vesting. QA/QC procedures and lab methods (Bureau Veritas) were disclosed; some assays remain pending.

Positive

• AX-25-708: 3.66 g/t Au over 17.6 m
• AX-25-708 high-grade: 35.98 g/t Au over 1.6 m
• High-grade core extended to ~500 m along strike
• High-grade core extended to ~300 m down dip
• AurMac Indicated MRE: 2.274 Moz Au
• AurMac Inferred MRE: 5.453 Moz Au

Negative

• Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability
• MRE relies on assumptions (gold price US$2,050/oz, 90% recovery) that could materially change the estimate
• Several reported intervals are low grade and require further drilling to convert to higher-confidence categories
• Some assays remain pending, leaving portions of the new interpretation unconfirmed

VANCOUVER, BC / ACCESS Newswire / November 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 with 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 gold on all samples. Samples returning >10 g/t Au were reanalysed by fire assay with gravimetric finish on a 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 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 kilometres 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 70km 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 10km west of the AurMac Gold Project. The Nitra Project 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.
