From discovery to a 25,000-metre drill program — Argus North continues to deliver. In just three months, Onyx Gold (TSX-V: ONYX | OTCQX: ONXGF) has rapidly advanced the Argus North Zone from a new discovery into one of the most exciting emerging gold systems in the greater Timmins Gold Camp. 7 of the first 9 holes at Argus North have returned grade-thickness values over 90 gram-metres, including: * MC24-163: 69.6 m @ 3.4 g/t Au (236.6 g*ms) * MC25-168: 91.0 m @ 1.8 g/t Au (163.8 g*ms) * MC25-171: 59.7 m @ 2.5 g/t Au (149.3 g*ms) * MC25-178: 52.2 m @ 2.2 g/t Au (114.8 gms) and 61.3 m @ 1.5 g/t Au (91.9 gms) * MC25-179: 66.8 m @ 1.4 g/t Au (93.5 g*ms) * MC25-180: 50.4 m @ 1.9 g/t Au (95.8 g*ms) This string of strong results has prompted Onyx to expand the Phase 1 drill program from 10,000 to 25,000 metres. Drilling to date has: * Confirmed over 200 vertical metres of continuous mineralization * Extended the gold mineralization to 4 meters to surface * Returned consistently strong grade x width metrics across multiple holes * Demonstrated zone proximity and association to the Pipestone Fault — a major regional structure hosting several large deposits Step-out drilling is ongoing, with more results to follow.

Onyx Gold Expands Argus North Discovery with Broad, Near-Surface Gold Intercepts Onyx Gold (TSX-V: ONYX | OTCQX: ONXGF) has released additional drill results from its 2025 program at the Argus North Zone on the Munro-Croesus Project, located 75 km east of Timmins, Ontario. These results expand the mineralized zone to over 200 meters vertically and confirm continuity to surface. Highlights include: * 52.2 m @ 2.2 g/t Au and a second deeper intercept of 61.3 m @ 1.5 g/t Au in hole MC25-178 * 66.8 m @ 1.4 g/t Au including 4.0 m @ 6.6 g/t Au in MC25-179 * 50.4 m @ 1.9 g/t Au from just 6.1 m downhole (~4 m vertically from surface), including 4.0 m @ 5.9 g/t Au in MC25-180 * Argus North Zone now defined from surface to 200 m vertical depth and remains open in all directions * Drill program expanded from 10,000 to 25,000 meters “These latest results from Argus North continue to highlight strong gold grades over broad widths and confirm that the zone remains open for expansion,” said Brock Colterjohn, President & CEO. “We are particularly encouraged by the near-surface mineralization intersected essentially at surface because this enables another exploration tool: mechanical stripping to expose and sample the zone in outcrop. We are mobilizing an excavator to site now and are keen to see what additional insights we can gather from surface work.” With an excavator mobilizing to site shortly, assays pending from additional step-out holes, and an expanded 25,000-meter drill program underway, Onyx Gold is well-positioned to continue advancing both Argus North and additional high-priority targets across its Munro-Croesus Project in the prolific Timmins Gold Camp.
