Star Metro - Banyan Gold Intersects 10,734 g/t Silver Over 1.7m, Confirming Structure Hosting High Grade Keno-Style Mineralization, AurMac, Yukon, Canada

Highlights from 2025 confirming the very high-grade Keno-style silver mineralization in Powerline:

• AX-25-803 - 5,625 g/t Ag over 3.4m within 1,841 g/t Ag over 10.4 metres ("m"), with very high-grade interval of 10,734 g/t Ag over 1.7m

• AX-25-790 - 110.7 g/t Ag over 0.8m within 22.06 g/t Ag over 5.7m

• AX-25-715 - 132 g/t Ag over 0.5m within 7.25 g/t Ag over 13.7m

"The high-grade Keno-style veins overprinting the gold mineralization represent a compelling new potential target for Banyan," said Tara Christie, President and CEO. "Hole AX-25- 803 returned results of 10,734 g/t over 1.7m, within 3.4m averaging 5,625 g/t, and a broader interval of 10.4 m at 1,841 g/t. Being able to successfully target this specific narrow, high-grade vein structure at depth is a technical success on top of the prospectivity for additional veins of silver mineralization we are finding in the Ag-1 vein zone. Parallel veins intersected in both current and historic drilling further reinforce the scale and exploration potential of the targeted zone."

• AX-25-803 was drilled 90m away from 2021's hole AX-21-142 and intersected the vein 20m from hole 142 at a depth of 115m.

• AX-21-142 included 1841.14 g/t Ag over 16.8m 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 (News Release, October 29, 2025)

"These high-grade silver results from hole AX-25-803 confirm continuity of the Ag-1 vein in central Powerline intersected originally in 2021 (1841.14 g/t Ag over 16.8m in AX-21-142) roughly 20m apart at depth," stated Duncan Mackay, Vice President Exploration of Banyan Gold. "The high-grade veins take advantage of different, steeply dipping, late brittle structures that strike northeast-southwest, different than the sheeted veins that host gold mineralization. We are working to determine the extent and potential for repetition of the thicker high-grade veins we see in holes AX-21-142 and AX-25-803 and improve targeting of silver mineralization across the deposit. Drillhole AX-25-803 was successful in confirming the orientation of the brittle structure and will help target extensions of the Ag-1 vein zone. Additional intersections in AX-25-790 and AX-25-803 indicate potential for sub-parallel veins adjacent to Ag-1; further testing will work to confirm the orientation and continuity of Ag-2 and Ag-3."

Figure 1: Plan map of new silver intersections in relation to high-grade silver zone in central Powerline (AX-21-142; see News Release dated October 29, 2025). Magenta shape shows approximate surface trace of the Ag-1 vein. Dashed magenta lines denote potential vein traces on surface (see Ag-2 and Ag-3 veins in figure 2). Mineralization is open along strike to the northeast and down-plunge (steeply plunging to the northeast; see cross section A-B; figure 2).

Figure 2: Cross-section A-B in Powerline. Silver intersections within drillholes AX-25-803 are consistent with late brittle feature for the Ag-1 vein intersected in drillhole AX-21-142 (see news release dated October 29, 2025). Two sub-parallel veins have been identified adjacent to the Ag-1 vein intersected in holes AX-21-142 and AX-25-803; Ag-2 and Ag-3 are north and south of Ag-1 respectively (magenta veins and dashed traces above).

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 from 2025 reported in this news release were analysed by Bureau Veritas of Vancouver, B.C., utilizing the multi-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). Samples returning >200 g/t Ag (MA250 or MA300) were analysed by multi-acid digestion ICP-ES MA370. If samples returned > 1,500 g/t Ag, they were analysed by fire assay with gravimetric finish on a 50g sample (FA550). If samples returned > 10,000 g/t Ag, they were analysed by fire assay 2g sample (FA501). 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. Historic 2019 Ag samples were analysed at BV by aqua regia digest ICP-ES/MS 37-element AQ200 (2019). Historic 2012 samples were analysed at ALS by 34-element four acid digest ME-ICP61. If samples returned > 100 g/t Ag, a 0.4g sample was analysed by four acid digest ICP-AES Ag-OG62. If samples returned > 1,500 g/t Ag, they were analysed by fire assay with gravimetric finish on a 30g sample (Ag-GRA21). Historic 2000 Ag samples were analysed at ALS by ICP-MS Ag 9225.

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 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.
