ONGold reports grab assays to 17.96 g/t Au from 2026 Phase 1 field program

Toronto, Ontario--(Newsfile Corp. - August 24, 2026) - ONGold Resources Ltd. (TSXV: ONAU) (OTCQB: ONGRF) (the " Company " or " ONGold ") is pleased to report results from its 2026 Phase 1 field exploration program, which consisted of helicopter-supported geological mapping and prospecting, orientation soil sampling at Gold Ridge, Big Dam and Bosworth, and ground geophysical surveying over the Discovery and Discovery West areas at Gold Ridge on the Ti-pi-ha-kaa-ning project (the " TPK Project "). The TPK Project hosts two large independent mineralized systems and comprises 2,835 cell claims covering 76,292 hectares within a highly favourable geological setting. TPK is located on the regional communities' winter-road network, which connects directly to the Musselwhite Gold Mine access road north of Pickle Lake (Figure 1). The Phase 1 program was undertaken to obtain additional field data to inform the Company's planned 2026 permitted drilling program and to complete regional exploration surveys. Wildfires in northwestern Ontario necessitated the rescheduling of the planned summer drilling program to the fall.

Phase 1 Field Program Exploration Highlights:

Gold Ridge:

Discovery Zone: Structural analysis of drill core has defined a potential southwest-plunging gold-bearing structure at the Discovery Zone. Drill hole GR-25-011, completed in 2025, returned 19.39 g/t Au over a core length of 8.20 m (11.8 to 20.0 m), including 359 g/t Au over 0.30 m (11.8 to 12.1 m). This zone is planned to be further drill tested this fall.

Sidewinder Zone: The newly discovered Sidewinder Zone, a 70-metre-long gold-bearing quartz-vein shear zone at Gold Ridge, returned grab assays up to 10.69 g/t Au with anomalous copper, including 10.69 g/t Au, 6.48 g/t Au and 5.21 g/t Au. Sidewinder has not been previously drill tested.

Discovery West: A re
