Banyan Gold Drills 1.90 g/t Au over 17.3m, Adds Fourth Drill Rig and Extends High-Grade Domains in Core of Powerline Deposit, Yukon, Canada

VANCOUVER, BC, AB / ACCESS Newswire / October 21, 2025 / Banyan Gold Corp. (the "Company" or "Banyan") (TSXV:BYN)(OTCQB:BYAGF) is pleased to announce it has intersected high-grade gold at surface in the core of the Powerline Deposit ("Powerline") at its AurMac Project ("AurMac") in the prolific Tombstone Belt, Yukon, Canada.

Selected Highlights Demonstrate Continuity of High-Grade in Core of Central Powerline Deposit:

  • AX-25-697 - 2.69 g/t gold ("Au") over 11.8 metres ("m") within 0.65 g/t gold over 72.5m; including 29.3 g/t Au over 0.4m, 21.04 g/t Au over 0.4m, and 2.26 g/t Au over 3.4m.

  • AX-25-700 - 3.07g/t Au over 3.6m within 0.69 g/t Au over 29.3m, and 1.90 g/t Au over 17.3m; including 33.00 g/t Au over 0.8m

  • AX-25-706 - 16.68 g/tAu over 1.1m within 2.39 g/t Au over 8.1m at surface

  • AX-25-709B - 2.55 g/t Au over 6.4m within 0.85 g/t Au over 22.9m

High-grade gold in drillholes AX-25-697, 700, 706, and 709B, as outlined above, highlight the potential for very high-grade gold intervals in Powerline and continue to reinforce continuity in the core of the deposit and confirm new 3D modelling of the high-grade mineralized domains. These intersections also have the potential to convert inferred ounces from the current Mineral Resource Estimate ("MRE") (Table 3) into indicated resources in the Powerline Deposit (Figure 1; Tables 1 and 2). To date, the Company has drilled over 30,000m (130 holes) on AurMac this year, with current drill program ongoing.

"With our recent $31.4-million strategic investment by Alpayana we have upsized our drill program to 40,000 m and have added a fourth drill rig," stated Tara Christie, Banyan President and CEO. "Our modelling and drilling suggests that the deposit is open in all directions, confirming the +1g/t Au zones and potentially extending the zones beyond the previously known mineralization."

"Our drilling in the core of Powerline (Figure 1) continues to confirm continuity of refined and high-grade mineralized domains," added Duncan Mackay, Vice President of Exploration. "With mineralized domains open down-dip (Figure 2) we also have the potential to add additional high-grade ounces while converting inferred ounces to indicated. We continue to intersect visible gold, in zones of high-grade mineralization (Figures 3 and 4), and throughout the Powerline deposit."

Figure 1: Plan map of the northeast portion of the Powerline Deposit. High-grade mineralization is associated with emplacement of sheeted veins in favourable host rocks, primarily based on rheology; more brittle rocks are favourable hosts for sheeted vein emplacement. Cross-section line for Figure 2 shown by gold line.

Sheeted-veins with visible gold, bismuth sulphosalts, and arsenopyrite are localized in higher concentrations in zones of more competent, brittle rocks (Figures 3 and 4). Veins are centimetre to decimetre in scale, generally with trace to 2% accessory minerals (bismuth sulphosalts and arsenopyrite). As rheology of the stratigraphy controls vein emplacement, detailed modelling is being carried out to refine the litho-structural model of the deposit and help define more refined mineralized domains. Many mineralized domains are open down-dip, with potential for more domains to be identified outside of the current mineralised envelope.

Figure 2: Cross-section of the Powerline Deposit at 466500 E. Refined mineralized domains (in magenta) intersected in the drillholes in this release reinforce continuity of high-grade mineralization. Down-drip extensions of mineralized domains have potential to convert additional waste blocks into ore as well as flatten the conceptual pit floor.

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 303 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 1:

  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.

1 The gold price and cost assumptions are consistent with current pricing assumptions and costs and, in particular, with those employed for recent technical reports for similar pit-constrained Yukon gold projects.
