VANCOUVER, BC / ACCESS Newswire / June 17, 2026 / Banyan Gold Corp. (the "Company" or "Banyan") (TSXV:BYN)(OTCQB:BYAGF) is pleased to announce it has intersected high-grade gold ("Au") mineralization in the Powerline Deposit ("Powerline") southwest of the main high-grade core. These diamond drill intersections highlight a new potential high-grade zone at the AurMac Project ("AurMac"), Yukon, Canada.

Highlights from New Powerline Southwest Zone:

• AX-26-853 - 13.00 g/t Au over 9.2m within 5.58 g/t Au over 21.7m, including high-grade interval of 62.66 g/t Au over 1.8m and;
  1.64 g/t Au over 11.5m within 0.70 g/t Au over 32.2m

• AX-26-842 - 0.96 g/t Au over 7.6m within 0.37 g/t Au over 33.9m

"The successful step-outs from 2025 in the southwest portion of Powerline, have defined a new potential high-grade zone (Figures 1 and 2), highlighted with drill results of 13.00 g/t Au over 9.2m, within 5.58 g/t Au over 21.7m in hole AX-26-853, including 62.66 g/t over 1.8m (see Figure 3, Table 1)," stated Tara Christie, President and CEO. "This very high-grade skarn-hosted mineralization (Figure 7) demonstrates the potential to discover and develop new mineralized zones at Powerline and AurMac in addition to high-grade domains associated with sheeted quartz veins (Figures 8 and 9). We are consistently intersecting visible gold as we are targeting high grade mineralized domains."

Analytical Method and Quality Assurance/Quality Control Measures

The reported work was completed using industry standard procedures, including a quality assurance/quality control ("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% of all samples submitted to analytical laboratories.

All geological data in the MRE was verified by Ginto Consulting Inc. ("Ginto") as being accurate to the extent possible, and to the extent possible all geological information was reviewed and confirmed. Ginto made site visits to the AurMac Project on September 15th, 2018, November 27th, 2019, August 30th to 31st, 2021, November 5th, 2022, and June 10, 2025, and observed Banyan's drilling and sampling techniques, as well as viewed AurMac drill core. Ginto confirms that the assay sampling and QA/QC sampling of core by Banyan provides adequate and good verification of the data and believes the work to have been done within the guidelines of NI 43-101.

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 analysed 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 >10 g/t Au were reanalysed by fire assay with gravimetric finish on a 50g sample (FA-550). High-grade samples with documented visible gold are also analysed using metallic screen fire assay (FS-652). Samples returning >200 g/t Ag (MA250 or MA300) were analysed by multi-acid digestion ICP-ES MA370. If samples returned > 1,500 g/t Ag, they were analysed by fire assay with gravimetric finish on a 50g sample (FA550). If samples returned > 10,000 g/t Ag, they were analysed by fire assay 2g sample (FA501). Bureau Veritas is an accredited lab following ISO/IEC 17025:2017 SCC File Number 15895. A robust system of standards, ¼ core duplicates and blanks has been implemented in the 2025 exploration drilling program and is monitored as chemical assay data becomes available.

About Banyan

Banyan's primary asset, the AurMac Project is located in the Traditional Territory of the First Nation of Na-Cho Nyäk Dun, in Canada's Yukon Territory. The AurMac deposit comprises two main deposits, the Airstrip and Powerline Deposits. Mineralization is characteristic of a Reduced Intrusion Related Gold system, hosted in auriferous cross-cutting 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 million ounces of gold ("Au") (167.3 M tonnes at 0.68 g/t) and an Inferred Mineral Resource of 4.985 Moz of Au (267.2 M tonnes at 0.58 g/t) (See MRE Table below; as defined in the 2014 CIM Definition Standards for Mineral Resources and Mineral Reserves incorporated by reference into NI 43‑101). The 303 square kilometres ("sq km") AurMac Project lies 40 kilometres 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.

MRE Table: Pit-constrained Indicated and Inferred Mineral Resources - AurMac Project

Notes to MRE Table:

1. The effective date for the MRE is May 15, 2026

2. The Mineral Resource Estimate was prepared by Marc Jutras, P.Eng., M.A.Sc., Principal, Ginto Consulting Inc., who is an independent Qualified Person as defined by NI 43-101.

3. 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.

4. The 2014 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. It is reasonably expected that the majority of Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration.

5. 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$3,500/ounce, US$2.75/t mining cost, US$11.50/t processing cost, US$2.00/t G+A, 90% gold recoveries, and 45° pit slopes.

6. The number of tonnes was rounded to the nearest hundred thousand and ounces 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 70 km 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 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 at 0.95 g/t Au and 6.94 g/t Ag) (as defined in the 2014 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 10 km west of the AurMac Gold Project. The Nitra Property 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 Corp. ("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.
