Star Metro - Banyan Gold Continues to Intersect High-Grade Gold in Powerline, AurMac Deposit, Yukon, Canada

Powerline Highlights from within areas classified as "waste" in the 2025 Resource block model:

• AX-25-739 - 1.55 g/t Gold ("Au") over 9.9 metres ("m") , AND 0.84 g/t Au over 18.7m , including 8.76 g/t Au over 1.5m;

• AX-25-793B - 1.44 g/t Au over 7.5m , within 0.53 g/t Au over 35.0m;

• AX-25-806 - 0.98 g/t Au over 11.0m , within 0.37 g/t Au over 34.0m;

AX-25-809 - 0.81 g/t Au over 9.0m, within 0.64 g/t Au over 14.6m;

• AX-25-818 - 1.57 g/t Au over 6.6m , within 0.74 g/t Au over 16.5m;

• AX-26-820 - 0.86 g/t Au over 10.2m , within 0.48 g/t Au over 60.0m.

Eastern Powerline (previously referred to as Aurex Hill Area) Highlights detailed below, which improve continuity and expand high-grade domains in satellite pit:

• AX-25-781 - 0.87 g/t Au over 6.0m, within 0.32 g/t Au over 24.5m;

• AX-25-786 - 0.73 g/t Au over 75.8m , including high grade interval of 27.9 g/t Au over 1.5m;

• AX-25-800B - 0.70 g/t Au over 10.9m , within 0.41 g/t Au over 46.9m

"A key objective of the 2025 drill program was to optimize and improve economics for the upcoming Preliminary Economic Assessment (PEA). The drillholes in this release were strategically targeted in areas identified by the 3D model as potential zones where waste blocks could be converted into high-grade ore by extending both new and previously identified mineralized domains," said Tara Christie, President and CEO. "These results successfully achieve that goal and demonstrate the continuity of high-grade gold mineralization associated with sheeted veins in the core and the eastern portion of Powerline Deposit."

Figure 2: Cross-section 466950mE in Powerline (See Figure 1). High-grade mineralization associated with sheeted veins extends high-grade mineralized domains and has potential to convert near-surface waste blocks into high-grade ore while confirming continuity of the mineralization in Powerline and effective targeting based on the new geologic model.

Exploration Update

With 5 drills operating at site, Banyan has now completed over 7,500 m of drilling.

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 5 :

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.
