Drill Results

June 26, 2026, TSX-V: BYN

VANCOUVER, BC, June 26, 2026 - Banyan Gold Corp. (the "Company" or "Banyan") (TSX-V:

BYN) (OTCQB: BYAGF) announces the filing of the Technical Report to support the updated

Mineral Resource Estimate ( “MRE”) in accordance with the Canadian Institute of Mining,

Metallurgy and Petroleum (“CIM”) Definition Standard incorporated by the reference in National

Instrument 43-101 (“NI 43-101”) for the AurMac Project (“AurMac”). The Technical Report (titled

“Technical Report, AurMac Property, Mayo Mining District, Yukon Territory, Canada) and dated

June 26, 2026, was prepared by Marc Jutras, P.Eng., M.A.Sc., Principal, Ginto Consulting Inc.,

Tysen Hantelmann, P.Eng., of JDS Energy & Mining Inc. and Frank Wright, P.Eng., of F. Wright

Consulting Inc. The Technical Report is available for review on SEDAR+ at www.sedar.ca and on

the Company’s website at www.banyangold.com.

As announced in the Company’s news release dated May 19, 2026, the updated MRE comprises

an Indicated Mineral Resource of 3.64 million oz of gold (“Au”) (167.3 M tonnes at 0.68 g/t

Au) and an Inferred Mineral Resource of 4.98 M oz of Au (267.2 M tonnes at 0.58 g/t Au) (as

defined in the 2014 CIM Definition Standards for Mineral Resources & Mineral Reserves

incorporated by reference into NI 43-101). The updated MRE is summarized below in Table 1.

The AurMac Project pit -constrained MRE is contained in two near/on -surface deposits: The

Airstrip and Powerline deposits. This new MRE exceeds the objectives set out for the 2025

diamond drill campaign at Banyan.

Notes to Table 1:

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 a 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.

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 c omprises

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.

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 compri ses 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 Tombsto ne 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.

OTCQB Venture Market under the symbol “ BYAGF”. For more information, please visit the
