VANCOUVER, BC / ACCESS Newswire / September 18, 2025 / Banyan Gold Corp. (the "Company" or "Banyan") (TSX-V:BYN)(OTCQB:BYAGF) is pleased to announce it has closed the 100% earn-in agreement on the AurMac Project ("AurMac") (the "Transaction"), previously announced on July 24th, 2025 with PricewaterhouseCoopers Inc., the receiver and manager (in such capacity, the "Receiver") for Victoria Gold Corp. ("Victoria"). Banyan had originally signed the option agreements on the properties in 2017, and by 2024, had earned 75%. The option agreements were originally to be completed in late 2025 and 2026. Pursuant to the previously announced definitive agreement to accelerate the options, Banyan has now earned the remaining interests (additional 25%) in the McQuesten and Aurex properties (which together comprise the core of the AurMac Project).

"With this closing, the strict timeline to complete the PEA is removed. Banyan will now be able to incorporate the results of our strategically targeted 2025 drilling into a PEA for 2026," stated Tara Christie, President and CEO." Banyan will now also upsize our 2025 drill program to over 40,000 metres."

AurMac hosts a gold 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 )(see Table 1 below).

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 291.8 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.
