Star Metro - Banyan Intersects 1.44 g/t Au over 33.2m, within 104.4m at 0.82 g/t Au and Extends Mineralization Between Deposits, AurMac Project, Yukon, Canada

Selected Highlights:

• AX-25-678 - 104.4 m at0.82 g/t Au including 33.2m at 1.44 g/t Au and 3.1m at 5.8 g/t Au

• AX-25-659 - 11.5m at 1.53 g/t Au

• AX-25-665 - 8.5m at 0.81 g/t Au including 4.2m at 1.29 g/t Au

• AX-25-670 - 29.1m at 1.04 g/t Au including 6.7m at 3.90 g.t Au

• AX-25-672 - 18.0m at 1.11 g/t Au including 3.8m at 4.31 g/t Au

• AX-25-674 - 16.0m at 1.15 g/t Au including 4.8m at 3.43 g/t Au

"These results continue to define higher grade zones ( +1 g/t material) at AurMac," stated Tara Christie, President and CEO. "While visible Gold is frequent in Powerline deposit style mineralization, the presence of visible gold in sheeted veins in close association with skarn mineralization in drillhole AX-25-678 at Airstrip highlights the continued potential for high-grade mineralization throughout the system. After intersecting some of the most enriched mineralization at Airstrip to date, AX-25-650 intersected 3.95 g/t Au over 38.1m (see News Release dated June 25, 2025), we continue to trace high-grade near-surface mineralization along strike and up-dip. Today's drill results highlight the potential to expand the footprint of Airstrip mineralization East and West, and also down dip and between the two deposits at AurMac."

Duncan Mackay, Vice President of Exploration, continued, "Step-out drilling at Airstrip continues to confirm the strength and continuity of mineralization as we test the limits of the system. Drillhole AX-25-659, collared northeast of Airstrip, intersected a new zone of at-surface mineralization including 4.0m at 3.16 g/t Au. This result demonstrates that mineralization remains open and indicates potential for further extension of this new zone down dip and along strike. The high-grade skarn mineralization in AX-25-678 ( as well as AX-25-670, AX-25-672, and AX-25-674) with individual samples of 0.6m at 11.3 g/t Au, 0.3m at 24.8 g/t Au, and 0.4m at 22.5 g/t Au shows the potential for very high-grade skarn mineralization in Airstrip, 250m down dip of the dyke contact and a little below the conceptual pit floor (Figure 2)."

Figure 1: Plan map of the Airstrip and Northern Powerline deposits. Follow-up on drill step outs east of Airstrip (AX-25-659 and 665) have identified potential along strike continuation of the deposit and possible expansion of the mineralized envelope up to 300m east. Up-dip and eastward step outs in drillholes AX-25-670 and 672 extend high skarn-grade mineralization outside of the conceptual MRE pit and remain open up-dip. Follow-up on the inter-pit fence in 2024 (location of Section 1 - Figure 2) indicates potential to expand Airstrip mineralization south and further link the two pits; a similar fence at the east of Airstrip also indicates potential to connect the pits.

Figure 2: 50m Cross Section - 466825mE. Intersection in AX-25-678 extends mineralization down dip at Airstrip. AX-25-661 and AX-25-674 intersect Powerline-style mineralization near surface and extend Airstrip mineralization at depth, with potential to further link pits.

Figure 3: Cross-section at 467525mE. Drill holes AX-25-670 and AX-25-672 intersect skarn-style mineralization with potential to extend mineralization envelope further up-dip. Drill holes AX-25-682 and AX-25-676 likely extend Airstrip mineralization south with potential to link the two pits.

High-grade gold mineralization in AX-25-678 (with multiple visible gold occurrences, Figure 4) includes intense calc-silicate skarn mineralization typical of Airstrip (Figure 5) as well as intense sheet vein development in the footwall quartzite (Figure 6). The high-grade mineralization, 104.4m at 0.82 g/t Auincluding 30.9m at 1.44 g/t Au (Table 1), is highlighted by internal intervals such as 7.2m at 3.17 g/t Au with 0.6m at 11.3 g/t Au and 0.3m at 24.8 g/t Au and 9.2m at 3.59 g/t Au, further demonstrating the pervasive alteration and mineralization at Airstrip.

Figure 5: Calc-silicate skarn mineralization and alteration of calcareous metasedimentary rocks in the Airstrip deposit, drillhole AX-25-678. The calcareous metasedimentary units in Airstrip remain mineralized and open down dip, between the main deposits.

Figure 6: Sheeted (discordant) vein mineralization in footwall quartzites (below skarn mineralization) at Airstrip drill hole AX-25-678. Visible gold intersected at 296.3m. High-grade mineralization stratigraphically below typical "Airstrip-style" mineralization reinforces the potential for expansion at Airstrip and across the deposit.

Regional Land Use Planning and Commitment to Working Respectfully with FNNND
Banyan Gold is pleased that the Yukon Government and First Nation of Na-Cho Nyäk Dun ("FNNND") announced a Memorandum of Understanding to initiate the Na-Cho Nyäk Dun regional land use planning on July 31, 2025. Advancing the NND regional land use plan is a long overdue step for FNNND's Traditional Territory and will support de-risking mineral exploration moving forward. Further, we acknowledge and fully respect the FNNND's August 1, 2025, media release, which emphasizes that any mineral staking within their Traditional Territory during the ongoing land-use planning process is unwelcome. In line with this directive, we confirm that we have not staked any claims since that date, and we will not be staking any further claims within the Traditional Territory while the planning process remains in effect.

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 M oz 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 215.3 square kilometres ("sq km") AurMac Project lies 40 km 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.
