The July 16, 2026 press release reports results from a further 17 holes on the Argus Gold System on Munro-Croesus.
Beyond the Headline
The July 16, 2026 press release reports results from a further 17 holes on the Argus Gold System on Munro-Croesus. Highlights are as follows:
Argus North
Argus North continues at depth with the zone now having been intersected to more than 700 m vertically and remains open. MC26-274A intersected 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 returned 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.
Argus Main
The Company reports that 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 intersected 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, this 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 returned 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.
New Northeast Target
The Argus trend is expanding with first-pass drilling 250 m northeast of Argus Main within massive and pillowed mafic flows intersecting gold mineralization along the projected Argus Fault corridor, opening a new area for systematic follow-up. Results include MC26-316: 2.6 g/t Au over 7.3 m; including 8.8 g/t Au over 1.5 m and MC26-314: 1.3 g/t Au over 5.7 m, including 2.2 g/t Au over 3.0 m.
Comments
Onyx continues to release excellent drill results from this massive drill program with high-grade intersections as well as long, low-grade intersections indicating strong potential for one or more major bulk tonnage gold deposits with high-grade shoots. The major target zones continue to be open along strike and at depth.
