Banyan Gold District Consolidation with Claim Purchase, AurMac Project, Yukon

VANCOUVER, BC / ACCESS Newswire / December 17, 2025 / Banyan Gold Corp. (the "Company" or "Banyan") (TSXV:BYN,OTC:BYAGF)(OTCQB:BYAGF) is pleased to announce the strategic acquisition of Trail Minto Claims (total 229 claims) located between Banyan's AurMac Project ("AurMac") and Nitra Project ("Nitra") properties from Mayo Lake Minerals Inc. (CSE:MLKM) completing a district consolidation of almost 720 square kilometres ("sq km") around the AurMac Project (Figure 1).

"With today's acquisition of the Minto Claims, the AurMac and Nitra properties have now grown to a contiguous 720 sq km land package covering the AurMac deposit (see Table 1 below) and an extensive prospective and underexplored land package," said Tara Christie, President and CEO. "Banyan has identified geophysical and surface geochemical trends which continue toward the Trail-Minto claims and Nitra claim block, indicating the potential for reduced intrusion-related gold mineralization."

Property Acquisition

Banyan has completed the purchase of 100% interest in a group of 229 quartz claims, covering 46 sq km, referred to as the Trail-Minto Claims ("the Claims") for a cash consideration of $1,000,000 and a 2% net smelter royalty ("NSR" or the "Royalty") to Mayo Lake Minerals Inc. Banyan may, at any time, elect to reduce the Royalty rate to 1% upon a payment of $1,000,000. All other previous royalties have been eliminated.

The claims are situated in-between and contiguous to the AurMac and Nitra properties (Figure 1). Application of the geological, geophysical and structural models developed by Banyan for AurMac highlights the prospectivity on the Trail-Minto claims. Banyan has identified geophysical and surface geochemical trends which continue toward the Trail-Minto claims and Nitra claim block, indicating the potential for reduced intrusion-related gold mineralization.

All of the claims that are now owned by Banyan, either by staking or purchase, preceded the Government of Yukon and the First Nation Na-cho Nyäk Dun signing a Memorandum of Understanding on July 31, 2025, to initiate the regional land use planning process.

Updated Disclosure on Banyan Share Registry

The company is aware that there continues to be old information about our shareholder registry held by external data providers which the company is working hard to correct. The company confirms that PricewaterhouseCoopers, in its capacity as receiver for Victoria Gold Corp. ("Victoria"), has divested of all its Banyan shares, as of October 15, 2025. The shares were originally issued to Victoria under the AurMac property earn-in agreement and through early financings. Since September, Banyan has welcomed notable new institutional and high net-worth shareholders and current information is maintained on the Banyan website

Yukon-BC Grid Connect

Banyan welcomes Prime Minister Carney's announcement referring the Northwest Critical Conservation Corridor-including the proposed Yukon-B.C. Grid Connect-to the Major Projects Office to accelerate this nation-building initiative. Banyan supports the federal recognition of the corridor's substantial potential to advance critical minerals development and clean power transmission while upholding Indigenous rights and project leadership. As outlined in the Yukon Development Corporation's Shared Grid / Shared Benefits report, the Yukon-B.C. Grid Connect could unlock up to C$7.6 billion in annual clean economic growth, support more than 36,000 long-term jobs, and enable up to 2,000 MW of new renewable energy. Connecting the Yukon's isolated grid to the Canadian grid through B.C. would enhance energy security, deliver clean power across Canada's Northwest corridor, and enable responsible development of mining projects, including Banyan's AurMac.

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 is contiguous with the 417 sq. km. Nitra Project, located 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.

Table 1: Pit-Constrained Indicated and Inferred Mineral Resources - AurMac Project

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.

In addition to the AurMac Project, the Company holds the Hyland Gold Project, located 70km 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 10km west of the AurMac Gold Project. The Nitra Project 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.

Banyan trades on the TSX-Venture Exchange under the symbol "BYN" and is quoted on the OTCQB Venture Market under the symbol "BYAGF". For more information, please visit the corporate website at or contact the Company.

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.
