Ongold Resources Announces Appointment Of Vice-President Exploration & Monument Bay Gold Project Update

(MENAFN- Newsfile Corp) Toronto, Ontario--(Newsfile Corp. - April 30, 2025) - ONGold Resources Ltd. (TSXV: ONAU) (OTCQB: ONGRF) (the " Company " or " ONGold ") is pleased to announce the appointment of Paul Dunbar as Vice-President, Exploration effective as of April 1, 2025. With nearly four decades of experience in geology and gold resource evaluations, Mr. Dunbar has held prominent roles in executive and senior management positions across Canadian exploration, development and production mining companies overseeing gold resource expansions in support of mining operations and evaluating and advancing exploration projects.

Although focused predominantly on gold exploration and development projects, his expertise spans a wide variety of geological deposit types, including Archean greenstone gold deposits, epithermal gold/silver systems, SEDEX deposits, and copper-gold porphyry projects. He has managed diverse teams of professionals and has considerable success in globally steering projects from the grassroots stage to advanced resource definition and development stage having worked throughout Canada, Nevada, Peru, East and West Africa, China and Mongolia.

As the Director of Exploration for Argonaut Gold Inc., he led his team in advancing exploration, expanding resources, and assisting to develop the Magino open pit gold producing mine operating in Dubreuilville, Ontario. This operation and 10,000 tpd mill and remaining Canadian assets were acquired by Alamos Gold Inc. in 2024.

MONUMENT BAY GOLD PROJECT UPDATE

Mr. Dunbar will lead the reactivation of exploration at the Monument Bay gold project as well as a detailed resource review. The objectives of the current exploration program at Monument Bay is as follows:

• Expand the geological understanding of the existing gold and tungsten deposits at the Monument Bay deposit and its mid-east zone.
• Conduct an Initial Phase I Field Exploration Program to evaluate all high-priority targets identified across the Monument Bay property (please see the Company's press release dated March 3, 2025 for further details).
• Undertake an induced polarization survey over the existing deposits as well as targets proximal to existing resources.
• Explore opportunities to conduct optical televiewer structural studies on previously drilled boreholes to re-enforce and deepen the understanding of the structural control mechanisms concentrating high-grade gold and tungsten mineralization within the Monument Bay deposit.
• Perform a comprehensive evaluation of historical gold-tungsten resources defined by previous operators. This includes assessing currently defined resource domains, cut-off grades, opportunities to expand the assay database through infill sampling and assaying, integrating drill hole data not previously incorporated in historic resource estimates, and identifying resource expansion opportunities within the main deposit. Historical resources were defined using US$1,200 gold and significantly higher gold prices will change the evaluation of the current deposits.
• Undertake a fixed-wing lidar/ orthophoto survey to support further regional exploration targeting and property-wide structural interpretation to identify new target areas to focus future exploration activities and drilling programs.

PROJECT RESOURCE GEOLOGIST

ONGold is also initiating a re-examination of the existing Monument Bay gold resource as well as resource expansion opportunities. In order to complete the analysis, ONGold has engaged an experienced resource geologist; Mr. Wally Dzick. As a highly experienced and internationally recognized Professional Geologist, Mr. Dzick has cultivated a distinguished career centered on precious metals exploration and mining, resource evaluation, statistical analysis and development, corporate due diligence with notable expertise in exploration and resource appraisals in gold and silver commodities. His experience spans across domestic and international assignments, including roles in strata-bound sediment-hosted copper and polymetallic replacement-style deposits.

His career includes significant tenures with leading global companies such as Barrick Gold and Newmont Mining, complemented with mid-tier juniors like Getchell Gold, Silver Standard Resources, and Summit Mining. As Chief Geologist for Barrick Gold at the Meikle Mine in Nevada, he successfully managed the geology department and developed strategies for optimizing resources through effective drilling programs. His proficiency in mine geology, quality assurance and quality control processes, ore control, mine-to-mill reconciliation, and resource modeling position him as a key player in the industry.

Kyle Stanfield CEO and Director of ONGold commented: "I am delighted Paul Dunbar has joined ONGold in this critical leadership role. He brings the right balance of grassroots exploration planning combined with expansive gold resource development expertise to our team. With the planned reactivation of exploration activities at the Monument Bay gold project, we are excited about next steps as we enter an unprecedented gold price environment."

Monument Bay Gold Project

The recently acquired Monument Bay Gold project in Manitoba represents a substantial acquisition of large known gold deposits. Monument Bay has had numerous mineral resources estimates completed by various Qualified Persons on behalf of various operators, which are no longer current under National Instrument 43-101 - Standards of Disclosure for Mineral Projects (" NI 43-101 "). The most recent unpublished NI 43-101 technical report (2017) (the " Historical Report ") for the Monument Bay deposit (formally the Twin Lakes Deposit) identified 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 includes only in-pit and resources with a cut off grade of 0.3 g/t gold.

Notes:
1) These mineral resources are historical in nature. Although compliant under NI43-101 at the time, resources should be updated to include more recent data, metals prices and cost assumptions.
2) Mineral resources that are not mineral reserves do not have demonstrated economic viability. There are no mineral reserves at the Monument Bay Project.
3) Block size was 10mX10mX2m.
4) Gold price at the time was assumed to be US$1,200/oz, and $CDN/$US of 1.30.
5) Operating costs for open pit mining were assumed to be US$1.46/tonne for mining, $US12.49/t for processing and $US1.54/t for general and administrative (G+A).
6) Pit constrained resources at 0.3 g/t Au cut off

New Gold Exploration Targets Identification

The compilation and new interpretive work announced by ONGold on March 3, 2025 resulted in the identification of five (5) new 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:

Ankerite/Gold Pond Area along the Twin Lakes Shear Zone (" TLSZ ");

AZ Zone (Easterly and Westerly strike extensions);

Newly discovered Central Zone;

Monument Bay Deposit West Extension, also located along the TLSZ immediately west of the Monument Bay deposit; and,

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.

Technical Information

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.

All technical data contained in this press release related to Monument Bay is considered historical in nature.

The Historical Report contains resource estimates that were calculated using cut-off grades of 0.3 grams per tonne (g/t) gold for open-pit resources. The 2015 pit shell was used to constrain the resource. The Mid-East and AZ Zones are not included in this estimate. This resource only considers open-pit resources and is pit-constrained. Subsequent resource modelling has indicated there is a high degree of variability in tonnage, metal grades, and contained metal as a result of different estimation methodologies and geological models.

This estimate, prepared prior to ONGold's acquisition of Monument Bay, is considered historical in nature. It is no longer current and should not be relied upon. The 2015 pit shell used to constrain the resource is outdated and would need to be updated to reflect current economic conditions and technical parameters. A qualified person has not done sufficient work to classify the historical estimates in this news release as current mineral resources or mineral reserves, and ONGold is not treating the historical estimates as current mineral resources or current mineral reserves. ONGold does not have any more recent estimates or data available with respect to these historical estimates and has not conducted sufficient work to establish the relevance and reliability of the historical resource estimates.

To verify and update this historical estimate to current NI 43-101 standards, additional work is required. This includes further drilling, a review of the geological model, and validation of previous findings under the oversight of a qualified person. Until such work is completed, investors are cautioned that the historical estimate does not meet current NI 43-101 standards, and any economic analysis or decisions based on this estimate should be avoided.
