Ongold Announces Agreement With Nibinamik First Nation & Initiation Of Exploration Program At TPK Gold Project

(MENAFN- Newsfile Corp) Toronto, Ontario--(Newsfile Corp. - September 4, 2025) - ONGold Resources Ltd. (TSXV: ONAU) (OTCQB: ONGRF) (the " Company " or " ONGold ") is extremely pleased to announce the signing of a Collaboration Agreement with Nibinamik First Nation (the " Collaboration Agreement "). Meaningful and consistent engagement with the community has resulted in an understanding that is transformational in terms of what the community and ONGold are initiating together. With the agreement in place, exploration diamond drilling of the Ti-pi-ha-kaa-ning (" TPK ") project was recently initiated and is expected to conclude during the latter half of September.

Kyle Stanfield, CEO and Director of ONGold, commented: "Through negotiation of the Collaboration Agreement with Nibinamik First Nation, we have demonstrated again that ONGold understands how to engage with communities in a meaningful way. We are thrilled to be working closely with Nibinamik First Nation as we undertake the diamond drilling exploration program at TPK".

The TPK Project hosts two large independent mineralized systems and is comprised of 2,431 cell claims covering an area of 47,796 hectares within a highly favorable geological setting. The Gold Ridge System (formerly Annex area), the focus of this current exploration program, occurs at the head of a large gold grain-in-till dispersal corridor and is located in the north-east portion of the expansive TPK property.

Gold Ridge System Previous Exploration Highlights

• Mineralized boulders returned assay values of up to 727 g/t gold, 111 g/t silver, and 4.1% copper .

• Drill hole NG-12-003C returned grades of up to 4.62 g/t gold over a core length of 5.5 m (from 145.6 m to 151.1 m), including 20.8 g/t Au over 1.0m (from 145.6 m to 146.6 m) .

• Drill hole NG-12-005C intersected 13.40 g/t Au over a core length of 1.90m (from 162.3 m to 164.2 m), including 41.5 g/t Au over 0.6m (from 162.3 m to 162.9 m).

Current Program

ONGold considers the Gold Ridge System to be a highly promising and largely untapped region, situated within a geologically advantageous setting. Early-stage exploration has already revealed encouraging signs of both gold and copper potential, underscoring the area's significant resource prospects.

An eight-hole diamond drill program totaling 2,400 metres is currently underway. This initiative aims to build upon the results of the 2012 drilling campaign while also evaluating grassroots targets. These targets have been identified through a combination of anomalous gold grain counts in till samples, boulders exhibiting elevated gold and copper values, and geophysical anomalies previously outlined by earlier ground surveys (Table 2 and Figure 2). Oriented core will be used to collect structural data to enhance the understanding of the structural controls of both gold and base metal mineralization at TPK.

Property Geology

The TPK Property is located in the Bartman – Lavoie greenstone belt of Oxford-Stull domain of the Sachigo Superterrane. The Stull-Wunnumin Fault Zone (" SWFZ ") is a regional-scale structure that forms the boundary between the Oxford-Stull terrane and the North Caribou terrane.

In the Gold Ridge System, rocks mapped as mafic and intermediate volcanics and interbedded sediments have been intruded by early gabbro and quartz diorite/granodiorite complexes. In the 2012 drilling, the contacts of mafic dykes with the diorite were found to be loci for the veins and shears carrying gold mineralization.

History of the Gold Ridge System

Previous property scale till sampling by previous operators defined a 10 km long X 3.5 km wide gold grains in till dispersion train (the Keeley Lake Train) of gold grains in till, which terminates in the Gold Ridge System area. Of 100 samples of mineralized boulders 24 returned anomalous gold values between 0.1 and 1.0 g/t Au and 9 assays > 1.0 g/t Au, including one that assayed 727 g/t gold, 111 g/t silver, 4.1% copper.

Subsequent diamond core drilling in 2012 consisted of 2,241m in 7 holes (Figure 1). The best assay intercepts are reported on Table 2. Significant gold, silver and copper values were most often found in quartz veins and thin shear structures at the contacts of mafic dykes and the quartz diorite host rock.

Limited ground magnetometer and induced polarization (" IP ") surveys were completed in 2012. These outlined NNE and ENE trends in the underlying rocks and identified new targets up-ice of angular boulders with anomalous gold and copper values.

Additional prospecting in 2017 resulted in several new gold occurrences being found, with 16 of 36 bedrock samples assaying more than 0.1 g/t Au, three of which assayed 1.28, 1.42 and 1.56 g/t Au, respectively. Additionally, three of these 36 samples returned anomalous (>500 ppm) copper values of 892, 736 and 4,370 ppm Cu, respectively. No other work has been completed since on this part of the TPK property.
