Press Release

For immediate release

ONGOLD ANNOUNCES FILING OF NI 43-101 TECHNICAL REPORT FOR THE

MONUMENT BAY GOLD PROJECT AND PROVIDES CORPORATE UPDATE

Toronto, Ontario, June 13, 2025 – ONGold Resources Ltd. (the “ Company” or “ONGold”) (TSXV:ONAU)

(OTCQB:ONGRF) is pleased to announce that the Company has filed on SEDAR + a technical report (the

"Report") prepared in accordance with National Instrument 43-101 – Standards of Disclosure for Mineral

Projects ("NI 43-101") describing historical mineral resource estimates for its Monument Bay Gold Project

(“Monument Bay”). The Report was prepared in accordance with the guidelines of NI 43-101 and the

mineral resource estimates in the Report are understood to have been estimated in conformity with

generally accepted CIM “Estimation and Mineral Resource and Mineral Reserve Best Practices” guidelines.

The full technical report dated May 30, 2025, with an effective date of March 3, 2025 is entitled “Technical

Report on the Monument Bay Project, Manitoba, NTS: 53K07 ”. The Report was prepared for ONGold

Resources Ltd. by Rodney Barber, B.SC . (Hons.), P.Geo. and can be found under the Company's issuer

profile at www.sedarplus.ca.

About the Project

Monument Bay is located in northeastern Manitoba, near the Ontario-Manitoba border, and represents

a district-scale exploration opportunity with significant gold and tungsten mineralization over a 40 km

strike length. Monument Bay is an advanced stage exploration asset with over 233,000 metres drilled in

more than 800 diamond core holes, while still having substantial exploration upside both within the

known deposits and along underexplored satellite zones.

The Report describes the historical exploration work completed at Monument Bay , particularly in the

period from 1987 to 2021, including geological mapping and prospecting, trenching, geochemical

sampling, airborne magnetometer and VTEM surveying, local ground induced polarization and

magnetometer surveys, local humus, B-horizon soil and biogeochemical surveys. A total of 233,410m of

diamond drilling has been completed in 818 holes, mostly focused on the Monument Bay Au-W Deposit.

In addition, 120 reverse circulation holes were completed between 2019 and 2021 on a very wide (1.5km

X 1.5km) spacing across the property . Collectively, this work has resulted in multiple gold discoveries,

most notably at the Monument Bay Au -W Deposit, Mid -East, AZ Zone and Gold Ridge areas along

important regional deformational/shear structures.

Previous operators have delineated three gold and tungsten mineralized zones on Monument Bay through

diamond drilling, field sampling programs and limited surface stripping: the Monument Bay Au-W Deposit,

the Mid-East Deposit and the AZ Zone. Three types of gold mineralization have been identified within

these zones associated with different gene rations of structures: (1) Quartz -tourmaline + /- pyrite-

arsenopyrite-pyrrhotite veins occur within both D1 and D3 shear zones , which strike easterly and dip

shallow and steeply to the south (2) Smoky quartz +/- pyrite-pyrrhotite-arsenopyrite-chalcopyrite veins

as well occur in steeply south dipping D3 shear zones and typically have higher sulphide content but lower

gold content than quartz-tourmaline veins and (3) quartz-albite-ankerite-scheelite +/-pyrite-arsenopyrite-

sphalerite-chalcopyrite-galena-stibnite are the dominant mineralization type observed in the Monument

Bay, Mid-East and AZ deposits.

The Report discloses a historical mineral estimate which identified approximately 2.3 million gold ounces

(58.0 million tonnes at an average grade of 1.24 g/t) in the “Measured” and “Indicated” Mineral Resources

categories, and 720,000 gold ounces (24.4 million tonnes at an average grade of 0.92 g/t) in the “Inferred”

Mineral Resources category. This consists of in-pit resources above a cut off grade of 0.3 g/t gold . This

historical mineral estimate, although compliant with NI 43-101 guidelines at the time it was prepared, is

historical and should not be considered current. A qualified person has not completed sufficient work to

classify this historical estimate as current mineral resources or mineral reserves and accordingly it should

not be relied upon. The author and the Company are not treating the historical estimate as current mineral

resources or mineral reserves. In order to verify the historical estimate, a qualified person needs to review

the historical data, review any work completed at Monument Bay since the date of the historical estimate

and complete a new mine ral resource estimate. The author of the Report and the Company view this

historical estimate as a conceptual indication of the potential size and grade of the gold-tungsten deposit

in the area, and this information is relevant to ongoing exploration efforts.

New Gold Exploration Targets Identification

The compilation and new interpretive work completed by ONGold in 2025 resulted in the identification of

five (5) target areas, detailed below, for field exploration investigations with the goal of defining new

targets for drilling. These zones are denoted and prioritized as follows:

1. Ankerite/Gold Pond Area along the Twin Lakes Shear Zone (“TLSZ”);

2. AZ Zone (Easterly and Westerly strike extensions);

3. Newly discovered Central Zone;

4. Monument Bay Deposit West Extension, also located along the TLSZ immediately west of the

Monument Bay deposit; and,

5. Gold Ridge along the Stull-Wunnumin Fault/ Deformation Zone.

The Company is focused on exploring target areas that have the best opportunity to provide gold resource

expansion opportunities. ONGold currently believes that the (1) Ankerite/Gold Pond area, (2) the AZ

Zone/Central Zone area, and (3) Monument Bay deposit west extension are the “highest priority” areas

having the highest potential to discover new gold resources.

An integrated, multi -disciplinary exploration program in two phases is recommended to advance

Monument Bay. A phase one exploration program would include a compilation of known geology data

and re-interpretation based on known geophysics, new, modern IP surveys over the western extension of

the Monument Bay Au-W deposit, The AZ Zone and the Mid-East Zone, followed up by geological mapping

and prospecting of any new targets and known, historical gold showings, the completion of an airborne

Lidar survey, conducting optical televiewer surveys on selected historical drill holes , complete an

expanded audit of the diamond drill hole database and initiate additional assaying of stored pulps for

tungsten.

The cost for all the above proposed work is budgeted at $2,855,600, which includes a contingency

allowance of 10%.

Contingent upon the results of phase one, a p hase two exploration program would include a 5,000m

diamond core drilling to test the best exploration targets and any possible resource expansion

opportunities in 10 to 20 holes. Additional geophysics, geochemistry and/or surface sampling may also be

appropriate.

The scientific and technical content of this press release has been reviewed and approved by Rodney

Barber, P. Geo. for ONGold, who is a " Qualified Person " as defined by NI 43 -101. Mr. Barber is the

President of ONGold and is not considered independent . Ongoing verification of scientific and technical

information is achieved by direct involvement in the exploration work.

Corporate Update Regarding Director Resignation

ONGold announces that, effective immediately, independent director Thomas Gallo has resigned from

the board of directors of ONGold in order to pursue other opportunities within the mining sector.

Mr. Gallo stated that, “with my greater responsibilities in my new role, which I am excited to be pursuing,

I unfortunately will not be able to give ONGold the attention that it deserves from an independent direc-

tor. I continue to believe in the ONGold team and its projects, and I’m confident that ONGold will find a

suitable replacement for me on its board of directors in the near term. I am looking forward to ON-Gold’s

future and will be monitoring its news releases closely.”

Kyle Stanfield, CEO of ONGold stated, “I would like to thank Tom for his contributions to ONGold. We

wish him the very best in his new role."

ONGold has not currently identified a replacement for Mr. Gallo’s seat on its board of directors but is

currently reviewing potential candidates. The Company is grateful to Mr. Gallo for his services and wishes

him the best in his future endeavors.
