BANYAN GOLD ADVANCES AURMAC TOWARD A PEA WITH ENGAGEMENT OF LEADING MINING CONSULTANTS, YUKON, CANADA

Banyan Gold Corp. has selected consultants for the first preliminary economic assessment (PEA) on the company's AurMac project. Banyan has engaged AMC Mining Consultants (Canada) Ltd., Lycopodium (Americas) Ltd., BGC Engineering Inc. and other independent contractors to complete the PEA in Q4 2026.

The PEA will incorporate the 2026 updated mineral resource estimate (MRE) (effective date of May 15; the technical report is available for review on SEDAR+ and the company's website) utilizing the results from the 43,700-metre drill program completed in 2025), focused on converting the higher-grade zones to indicated, upgrading of undrilled or unestimated areas that were thus classified as waste blocks to mineralized blocks, and optimizing the potential starter pits in support of maximizing the economics of the PEA, which is expected in Q4 2026.

The study will highlight the economics for AurMac's large gold endowment and benefits from strong local infrastructure, including existing highways, roads, hydro power lines and cellphone service. Additionally, Banyan continues to undertake metallurgy studies to support the PEA to optimize the grind size and reagent consumption to maximize the project economics.

"Banyan is working with global leaders in mine engineering, process design and geotechnical assessment to deliver a high-quality PEA for AurMac in Q4 2026," stated Tara Christie, president and chief executive officer. "Banyan's drill program for 2026 is focused with 60,000 metres dedicated to refining the deposit based on updates following the PEA. This program aims to demonstrate that the deposit is open in all directions. Additionally, another 10,000 metres will be allocated towards using our understanding of the geophysics and geology for the region to unlock new targets within our 830-square-kilometre properties, including AurMac and Nitra."

About Banyan Gold Corp.

Banyan's primary asset, the AurMac project, is located in the traditional territory of the First Nation of Na-Cho Nyak Dun, in Yukon, Canada. The AurMac project comprises two main deposits: the Airstrip and Powerline deposits. Mineralization is characteristic of a reduced intrusion-related gold system, hosted in auriferous crosscutting sheeted quartz veins and replacement-style mineralization hosted in skarn horizons. The current mineral resource estimate (MRE) for the AurMac project has an effective date of May 15, 2026, and comprises an indicated mineral resource of 3,639,000 ounces of gold (167.3 million tonnes at 0.68 g/t) and an inferred mineral resource of 4,985,000 ounces of gold (267.2 million tonnes at 0.58 g/t) (see MRE table below; as defined in the 2014 CIM (Canadian Institute of Mining, Metallurgy and Petroleum) definition standards for mineral resources and mineral reserves incorporated by reference into NI 43-101). The 303-square-kilometre AurMac project lies 40 kilometres from Mayo, Yukon. The AurMac project is transected by the main Yukon highway and benefits from a 69-kilovolt-ampere three-phase power line, existing power substation and cellphone coverage.

In addition to the AurMac project, the company holds the Hyland gold project, located 70 kilometres northeast of Watson Lake, Yukon, along the southeast end of the Tintina gold belt 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 square kilometres), accessible by a network of existing gravel access roads. The updated MRE comprises an indicated mineral resource of 337,000 ounces of gold and 2.63 million ounces of silver (11.3 million tonnes at 0.93 g/t Au and 7.27 g/t Ag) and an inferred mineral resource of 118,000 ounces of gold and 860,000 ounces of silver (3.9 million tonnes at 0.95 g/t Au and 6.94 g/t Ag) (as defined in the 2014 CIM definition standards for mineral resources and mineral reserves incorporated by reference into NI 43-101), effective Sept. 1, 2025, and with technical report filed on SEDAR+ on Oct. 27, 2025.

Banyan also holds the Nitra gold project and Seattle-Goodman Creek project, which are grassroots exploration projects located in the Mayo mining district, adjacent to the AurMac gold project. These properties lie in the northern part of the Selwyn basin and are 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 properties, including the Morrison Creek and Minto Creek stocks. The properties are 100 per cent owned by Banyan and cover over 530 square kilometres. The properties are accessible by road along the Silver Trail Highway, the South McQuesten road and a network of other smaller roads across the properties.
