Spotlight on the Argus Zone – A Rapidly Emerging Gold System at Munro-Croesus Onyx Gold’s recent results at the Argus Zone continues to outline a growing, near-surface gold system with strong potential for bulk-tonnage mineralization. The most recent discovery, Argus North, expands the system significantly and remains open in all directions. MC24-163 drill highlights from Argus North: - 69.6m of 3.4 g/t Au - Including 34.5m of 5.4 g/t Au - Including 9.5m of 13.9 g/t Au This zone is hosted in the same variolitic mafic volcanics as Argus Main, where previous drilling outlined a ~750 x 200m mineralized footprint, including: - 63.3m of 0.99 g/t Au, incl. 17.4m of 2.2 g/t Au (MC24-166) - 136.0m of 0.54 g/t Au, incl. 4.5m of 4.88 g/t Au (MC22-110) Argus is positioned near existing infrastructure and mills in the Timmins Gold Camp  — a key strategic advantage as Onyx continues to build scale and momentum.

Unlocking the Next Chapter in Timmins Gold Exploration In the early 1900s, the Croesus Mine became one of Ontario’s highest-grade gold producers—averaging 95.3 g/t Au. Its discovery sparked a land rush, with surrounding patents quickly claimed and held in families for over a century. That fragmentation created an opportunity for consolidation—and that’s where Onyx Gold comes in. Over the past five years, Onyx Gold (TSXV: ONYX | OTCQX: ONXGF) has strategically assembled a 107 km² district-scale land package around the historic Croesus Mine—an area never before unified under a single exploration company. This consolidation is already paying off: - Three new discoveries since 2022: Argus Main, GM Vein, and Argus North - - Argus North (April 2025): 69.6m of 3.4 g/t Au, including 34.5m of 5.4 g/t Au - Part of the discovery made on a recently acquired patent claim—held privately for over 100 years - Strong pipeline with 35+ near-surface gold occurrences, with grades up to 2,500 g/t Au - All within 75 km of Timmins and near multiple mills with excess capacity By consolidating this historically fragmented region, Onyx has unlocked the ability to explore the Munro-Croesus Project on a meaningful scale—bringing modern exploration to one of Canada’s most prolific mining camps.

Consistency of mineralization in drill hole MC24-163 highlights the potential at Argus North. The 34.5-meter interval averaging 5.4 g/t gold in MC24-163 is characterized by consistent high- grade results across much of the section — not just isolated high-grade samples. From 265.5m to 300.0m, multiple samples returned over 1 g/t Au, including: - 76.4 g/t Au (293–294m) - 28.1 g/t Au (294–295m) - 11.2 g/t Au (269.3–270m) - 10.9 g/t Au (292–293m) The consistent grade distribution over tens of meters supports the presence of continuous gold mineralization within the zone. This discovery hole is the first to test the Argus North Zone, which remains open in all directions. Additional drilling is planned to assess continuity towards the surface and at depth, as well as along strike.
