BANYAN GOLD INTERSECTS HIGH-GRADE MINERALIZATION AT NEWLY IDENTIFIED ROARING FORK ZONE, VISIBLE GOLD AT SEATTLE CREEK ZONE, NITRA PROJECT, YUKON

Banyan Gold Corp. has intersected visible gold and high-grade mineralization in its first exploration drill holes at the Nitra gold project. These intersections have potentially identified new discoveries within the Roaring Fork zone and the Seattle Creek zone at Nitra, approximately 25 kilometres west of the AurMac deposit on claims owned 100 per cent by Banyan with no underlying royalties. These are the first two of 11 exploration targets that Banyan has identified on its broader 830-square-kilometre AurMac and Nitra land packages in the Mayo mining district in Yukon.

Highlights from Roaring Fork zone at Nitra:

• NT-26-001 -- 1.62 grams per tonne gold over 5.0 metres:
  • Including high grade of 17.80 g/t Au over 0.4 m.

Note: This release contains gold fire assays from top of hole to 285 m, see text below.

"We are very excited to report the Roaring Fork discovery at Nitra, indicating a new mineralized system 25 km west of the AurMac footprint," stated Tara Christie, president and chief executive officer. "Diamond drill hole NT-26-001 intersected visible gold, high densities of mineralized extensional veining, and high-grade gold mineralization associated with quartz veins and bismuth-sulphosalts, similar to what we see at AurMac and within the top 80 metres from surface. We are also pleased to announce a second target zone approximately five km north at Seattle Creek, with large extensional quartz veins with multiple visible gold instances, bisthmuth sulphosalts and sulphide replacement-style mineralization of calcareous metasedimentary rocks. While it is early days in understanding the scope of these discoveries, we are seeing similar vein-hosted mineralization in adjacent drill holes."

In June, 2026, Banyan announced the commencement of its greenfield exploration diamond drilling program at Nitra. The Nitra project benefits from a network of extensive roads established by previous and continuing placer mining activities near the targets. The diamond drill program is utilizing two helicopter-supported drills to minimize initial footprint and expedite testing of the targets. Over 7,500 metres of drilling will be completed to test 11 regional targets identified through new geophysical surveys, soil geochemical anomalies, knowledge of placer-mining locations and prospecting. The objective of the program is to identify potential satellite deposits by discovering additional expressions of reduced intrusion-related gold systems (RIRGs) in the highly prospective greenfield zones surrounding the AurMac deposit, where over 95 per cent of the district-scale AurMac and Nitra land package remains untested by drilling. A third drill is being mobilized to site to accelerate the greenfield exploration program.

"The rocks at the Roaring Fork zone and Seattle Creek have all the geologic ingredients we are looking for in our targeting," stated Duncan Mackay, vice-president, exploration. "A difference from AurMac is the presence of highly altered and strained volcanic rocks amongst the typical metasedimentary rocks of the Yusezyu formation, which are a prime host for brittle strain and quartz vein emplacement. We are seeing abundant mineralized shear veins with secondary extensional veins overprinting and local high-grade gold with anomalous gold throughout the portion of the hole for which we have received assays. Numerous instances of visible gold, high-grade gold intervals, a late lamprophyre dike (indicative of a long-lived structural corridor), and notable shear and extensional veins hosting bismuth sulphosalts on our first, second and sixth drill holes of the regional exploration program is very encouraging for the success of our additional nine targets generated by our team and supplemented with machine learning (AI)."

A combination of soil geochemical anomalies (gold, bismuth and arsenic) and geophysical signatures (resistive anomaly) were used to identify the target at the Roaring Fork zone. These targeting indicators were combined with proximal placer mining in the creek drainage to locate and prioritize the targets. Mineralization at the Roaring Fork zone is predominantly hosted in two styles of quartz vein: crosscutting extensional veins hosting bismuth sulphosalts, arsenopyrite, pyrite and locally sphalerite and foliation subparallel shear veins hosting bismuth sulphosalts, arsenopyrite and pyrite. Quartz veins are most concentrated near the margins of deformed and altered volcanic units, which may act as rigid buttresses to concentrate mineralizing fluids and favourable local strain regimes allowing for vein emplacement. The top 300 m of drill hole NT-26-001 exhibited the favourable mineralization; the lower 300 m of the drill hole was extended to test additional shear veins identified during daily quick logging and to provide greater geologic context for the area and for future drilling. Outcrop exposure is very limited across Nitra, with no outcrop within 200 m of the drill collar.

Only assays for the top 285 m of the drill hole have been received to this time; assays for the lower half of diamond drill hole NT-26-001 and all of NT-26-002 and NT-26-006 are pending.

Analytical method and quality assurance/quality control measures

The reported work was completed using industry-standard procedures, including a quality assurance/quality control 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 person 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 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 analyzed by Bureau Veritas of Vancouver, B.C., utilizing the four-acid digestion ICP-ES 45-element MA-200 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.
