BANYAN GOLD EXPANDS HIGH-GRADE DOMAINS AT POWERLINE, AURMAC PROJECT, YUKON, CANADA

Banyan Gold Corp. has intersected high-grade gold mineralization in the Powerline deposit west of the main high-grade core. These diamond drill intersections highlight new expansion potential and domains in a portion of Powerline at the AurMac project in Yukon, Canada.

Highlights from Powerline West:

• AX-26-833 -- 0.79 gram per tonne gold over 13.9 metres and 1.94 g/t Au over 7.6 m;
• AX-26-834 -- 1.38 g/t Au over 7.7 m within 0.61 g/t Au over 21.1 m;
• AX-26-841 -- 1.00 g/t Au over 13.7 m within 0.47 g/t Au over 41.3 m;
• AX-26-844 -- 0.79 g/t Au over 12.5 m;
• AX-26-854 -- 1.12 g/t Au over 13.1 m within 0.72 g/t Au over 24.6m;
• AX-26-861 -- 1.06 g/t Au over 9.6 m within 0.62 g/t Au over 20.0 m, including a high-grade interval of 6.29 g/t Au over 1.0 m.

"Banyan Gold has intersected new high-grade domains in Powerline West and visible gold in the initial drill holes of the season," stated Tara Christie, chief executive officer and president. "With our new MRE [mineral resource estimate] and upgraded 3-D model, we are able to identify and target new domains in areas of the deposit that have not been drilled in several years. High-grade domains have been identified just outside of the conceptual pit boundary for the 2026 MRE, indicating potential for up-dip and along-strike expansion of these zones."

Expanded mineralized domains associated with altered metasedimentary rocks hosting crosscutting sheeted veins have been identified in drilling from 2026 in Powerline West. Previous drilling in the area was completed at 100-metre spacing, which resulted in few mineralized domains being identified. Intersecting visible gold in the first drill hole of the season, in an area previously characterized by limited high-grade mineralization, is promising for the potential to upgrade the domains as continuity is tested for indicated conversion. Additionally, it identifies potential new domains below the conceptual pit floor and north and west of the pit boundary.

Analytical method and quality assurance/quality control measures

The reported work was completed using industry-standard procedures, including a QA/QC program consisting of the insertion of certified reference materials, field duplicates and coarse blanks into the sample stream and utilizing certified independent analytical laboratories for all assays. Additionally, historic QA/QC data and methodology on the AurMac project were reviewed and will be summarized in the technical report. The qualified persons detected no significant QA/QC issues during review of the data.

A robust system of standards, core duplicates and coarse blanks was implemented in all Banyan drilling programs and was monitored as chemical assay data became available. All control samples were within accuracy and precision thresholds required to meet data quality standards. These control samples amounted to approximately 10 per cent of all samples submitted to analytical laboratories.

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 Bureau Veritas's 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 analyzed 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 greater than 10 g/t Au were reanalyzed by fire assay with gravimetric finish on a 50-gram sample (FA-550). High-grade samples with documented visible gold are also analyzed using metallic screen fire assay (FS-652). Samples returning greater than 200 g/t silver (MA250 or MA300) were analyzed by multiacid digestion ICP-ES MA370. If samples returned greater than 1,500 g/t Ag, they were analyzed by fire assay with gravimetric finish on a 50-gram sample (FA550). If samples returned greater than 10,000 g/t Ag, they were analyzed by fire assay two-gram sample (FA501). Bureau Veritas is an accredited lab following ISO/IEC 17025:2017 SCC file No. 15895. A robust system of standards, one-fourth core duplicates and blanks has been implemented in the 2026 exploration drilling program and is monitored as chemical assay data become available.

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.

Banyan trades on the TSX Venture Exchange under the symbol BYN and is quoted on the OTCQB Venture Market under the symbol BYAGF.
