# Onyx Gold Extends Argus North to More than 700 Metres Depth with 3.5 g/t Gold over 28.1 Metres *2026-07-16T07:00:00-04:00* Onyx Gold Extends Argus North to More than 700 Metres Depth with 3.5 g/t Gold over 28.1 Metres Argus Main Returns 1.0 g/t Gold over 93.0 Meters; New Drilling 250 Meters Northeast Intersects 2.6 g/t Gold over 7.3 Meters Vancouver, British Columbia--(Newsfile Corp. - July 16, 2026) - Onyx Gold Corp.**(TSXV: ONYX) (OTCQX: ONXGF)**("**Onyx**" or the "**Company**") is pleased to report results from 17 drill holes at its 100%-owned Munro-Croesus Project ("**Munro-Croesus**" or the "**Project**"), located 75 km east of Timmins, Ontario. The results extend gold mineralization at both Argus North and Argus Main and identify a new area of mineralization 250 m northeast of Argus Main along the projected Argus Fault corridor. The most significant result is from Argus North, where hole MC26-274A returned **3.5 g/t gold **("**Au**") **over 28.1 meters**("**m**"), including **5.3 g/t Au over 17.8 m**. Drilling has now intersected Argus North from near surface to more than 700 m vertical depth, and the zone remains open at depth and along strike. At Argus Main, three (3) deeper holes continued to intersect broad gold mineralization, including **1.0 g/t Au over 93.0 m**in hole MC26-324. Approximately 250 m to the northeast, first-pass drilling intersected **2.6 g/t Au over 7.3 m**in a previously undrilled area, providing a new target for follow-up. **Highlights from Argus North** - Argus North continues at depth: the zone has now been intersected to more than 700 m vertically and remains open. - MC26-274A:**3.5 g/t Au over 28.1 m**, including **5.3 g/t Au over 17.8 m**, including **23.1 g/t Au over 1.0 m**and **11.4 g/t Au over 2.0 m** - MC26-271:**3.5 g/t Au over 19.0 m**, including**8.3 g/t Au over 6.6 m**, including**24.3 g/t Au over 1.0 m** **Highlights from Argus Main** - Argus Main is developing as a broad mineralized system: all three holes reported from the current step-out program returned multiple gold intervals, including higher-grade sections within wider envelopes. - MC26-324: **1.0 g/t Au over 93.0 m**, including **2.0 g/t Au over 20.0 m**, including **9.8 g/t Au over 1.0 m**; plus a separate interval of **0.9 g/t Au over 33.0 m**, including **3.0 g/t Au over 6.0 m**. Importantly, the hole finished in strong mineralization, returning up to **19.3 g/t Au over 0.7 m**in the final four meters and ending in **1.4 g/t Au over the last meter**, indicating the system could continue at depth. Follow-up drilling is planned to extend the hole and test for further mineralization. - MC26-317:**0.8 g/t Au over 98.9 m**, including **1.1 g/t Au over 35.8 m**and **2.7 g/t Au over 5.9 m** **Highlights from New Northeast Target** - The Argus trend is expanding: first-pass drilling 250 m northeast of Argus Main within massive and pillowed mafic flows has intersected gold along the projected Argus Fault corridor, opening a new area for systematic follow-up. - **MC26-316: 2.6 g/t Au over 7.3 m**; including 8.8 g/t Au over 1.5 m - **MC26-314: 1.3 g/t Au over 5.7 m**; including 2.2 g/t Au over 3.0 m "Every phase of drilling continues to strengthen our understanding of the Argus Gold System," said Brock Colterjohn, President & CEO. "Today's results demonstrate that both Argus North and Argus Main continue to grow with depth while maintaining the broad, continuous style of mineralization that has become characteristic of the system. Just as importantly, our first drill holes completed 250 m northeast of Argus Main intersected gold mineralization, highlighting the broader prospectivity of the Argus Fault corridor beyond the areas we have drilled to date." "With four drill rigs operating and more than 110,000 m of drilling planned for this drill program, we remain focused on systematically expanding the known zones while testing additional targets across the corridor. We believe we are still in the early stages of defining the full scale of the Argus Gold System." **Discussion of Argus North Drill Results** Nine (9) holes tested the west-northwest down-plunge extension of Argus North between approximately 350 and 716 m vertical depth. The drilling continued to intersect the same broad style of altered and mineralized volcanic rocks seen in the shallower part of the zone. Hole MC26-298A is the deepest intersection reported to date and confirms that the mineralized system remains present more than 700 m below surface. **Significant Intervals from Argus North** - **1.1 g/t Au over 29.0 m**, in drill hole MC26-268, including - 3.1 g/t Au over 6.0 m - **3.5 g/t Au over 19.0 m**, in drill hole MC26-271, including - **8.3 g/t Au over 6.6 m**, including - 24.3 g/t Au over 1.0 m - **3.5 g/t Au over 28.1 m**, in drill hole MC26-274A, including - **5.3 g/t Au over 17.8 m**, including - 23.1 g/t Au over 1.0 m, and including - 11.4 g/t Au over 2.0 m - **2.9 g/t Au over 4.0 m**, in drill hole MC26-293A, including - 8.1 g/t Au o
