Banyan Gold Corp.: Banyan Gold Continues to Extend Powerline Mineralization Beyond Existing Resource and Between Deposits, AurMac, Yukon, Canada

VANCOUVER, BC / ACCESS Newswire / December 9, 2025 / Banyan Gold Corp. (the "Company" or "Banyan") (TSXV:BYN)(OTCQB:BYAGF) continues to expand and upgrade the Powerline Deposit ("Powerline") at its AurMac Project ("AurMac"), First Nation of Na-Cho Nyäk Dun Traditional Territory, Yukon. The diamond drillholes reported here intersected new high-grade domains extending Powerline mineralization to a new area southwest of the main deposit and demonstrating the continuity of high-grade in the central Powerline deposit and between the Airstrip Deposit.

Highlights:

• AX-25-690 - 1.15 g/t Au over 10.5m within 0.74 g/t Au over 45.5m, including high-grade intervals of 6.82 g/t Au over 1.9m and 9.75 g/t Au over 1.0m

• AX-25-694 - 4.27 g/t Au over 2.0m within 0.62 g/t Au over 28.6m

• AX-25-724 - 4.60 g/t Au over 5.9m within 0.64 g/t Au over 55.4m; including high-grade interval of 14.90 g/t Au over 1.5m

• AX-25-728 - 0.86 g/t au over 16.5m and 1.03 g/t au over 6.8m

• AX-25-741 - 1.97 g/t Au over 3.3m within 0.29 g/t Au over 78.2m

• AX-25-746 - 1.70 g/t Au over 5.7 m within 0.92 g/t Au over 18.8 m

• AX-25-748 - 3.41 g/t Au over 0.5m and 0.65 g/t Au over 12.2m within 0.30 g/t Au over 89.1m

Banyan Gold has completed its 2025 drilling program with 178 holes over 42,700 m completed; with the last core shipped to the assay lab from camp last week. Thank you to our team, service providers, suppliers, consultants, and partners for a productive year.

"We have successfully intersected high-grade intervals at the Resource pit edge with additional sheeted veins hosting coarse sulphosalts, sulphides and visible gold in follow-up step outs 100 and 400 m from known mineralisation, with assay results pending (holes AX-25-772 and -779 respectively, Figure 5)," said Tara Christie, Banyan President and CEO. "Our new geologically supported mineralisation model continues to provide opportunities to upgrade portions of our deposit by converting waste blocks to high-grade ore, reducing strip ratios within the conceptual pit and by expanding the mineralized envelope to add ounces."

Continued drilling at Powerline has successfully confirmed mineralized domains in the core of Powerline (Figure 3), refined and extended mineralization between the Powerline and Airstrip main pits (Figure 2) and extended mineralization with potential to convert waste blocks in the southwest of Powerline (Figure 5).

Figure 2: Intersections reported in this news release, AX-25-688, -690, -692, further define the geologically based mineralized domains (magenta ellipses) and results demonstrate potential for extension along strike and down dip.

Figure 3: High-grade mineralization in zones from AX-25-719, -728, -724, -732 support continuity of mineral domains in the core of Powerline. Mineralized domains are open to depth with potential for further down dip extension.

Gold mineralization in southwest Powerline is consistent with mineralization seen in the core of Powerline; gold mineralization is associated with discordant sheeted quartz veins hosting sulphosalts and sulphides (predominantly sphalerite, arsenopyrite) (Figure 3) which is preferentially hosted in silicified/altered host rocks.

Figure 4: Mineralized zone from drillholes AX-25-690. Abundant discordant veining with coarse Bi-sulphosalts and arsenopyrite spatially associated with silicification and skarn-style mineralization (replacement mineralization of calcareous metasedimentary units).

Figure 5: Cross-section of the Powerline Deposit looking at AZM 135. Potential mineralized domain (in magenta) intersected in the drillholes in this release and show potential for down-dip extension, waste block conversion, and expansion of mineralized envelope to step out drillholes. Drillhole AX-25-779 (100m south, assays pending) intersected coarse sulphosalts and sphalerite in discordant quartz veins hosting visible gold (Figure 3). Results are also pending from a 400 m step out drillhole AX-25-772 that intersected similar Bi-Sb sulphosalt bearing discordant quartz veins.

Figure 6: Mineralized interval from drillhole AX-25-746. High vein density, Bi-Sb sulphosalts and visible gold are indicative of high-grade mineralization, confirmed by assay results.

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 ("Moz") 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 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.

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.
