Onyx Gold drills 60.8 m of 1.2 g/t Au at Munro-Croesus

Executive Summary
- Onyx Gold reported significant near‑surface gold intercepts from four step‑out drill holes and multiple surface channel samples at the Argus North zone of its 100 % owned Munro‑Croesus project.
- Intercepts include high‑grade intervals such as 3.0 m @ 5.9 g/t Au (hole MC25‑200) and 7.4 m @ 8.4 g/t Au (Channel G), confirming a wide (>100 m strike) mineralized zone that extends from surface to >350 m depth.
- The results come as the company finalizes a $20 M bought‑deal financing and an upsized $6.4 M non‑brokered financing, leaving the 25,000‑m drill program fully funded through 2026.
Key Details
- Drill Hole MC25‑200: 60.8 m @ 1.2 g/t Au overall; includes 3.0 m @ 5.9 g/t Au.
- Drill Hole MC25‑202: 37.8 m @ 1.8 g/t Au overall; includes 8.6 m @ 5.0 g/t Au.
-
Drill Hole MC25‑204: 37.5 m @ 1.2 g/t Au overall; includes 10.2 m @ 2.4 g/t Au.
-
Channel A: 10.7 m @ 0.6 g/t Au overall; includes 3.1 m @ 7.4 g/t Au.
- Channel B: 8.9 m @ 0.9 g/t Au overall; includes 2.8 m @ 1.6 g/t Au.
- Channel C: 21.3 m @ 2.0 g/t Au overall; includes 4.0 m @ 5.0 g/t Au.
- Channel D: 15.5 m @ 1.6 g/t Au overall; includes 6.5 m @ 2.8 g/t Au.
- Channel E: 7.4 m @ 4.9 g/t Au overall; includes 3.9 m @ 8.4 g/t Au.
- Channel F: 3.4 m @ 1.8 g/t Au overall; includes 1.0 m @ 4.0 g/t Au.
- Channel G: 7.4 m @ 4.9 g/t Au overall; includes 3.9 m @ 8.4 g/t Au (duplicate of E, reported separately).
-
Channel H: 15.4 m @ 2.2 g/t Au overall; includes 2.0 m @ 8.4 g/t Au.
-
Total drilling completed to date: 64 holes (assays announced for 18 holes); ~20,000 m (~80 %) of the expanded 25,000‑m program drilled.
-
Surface work: 174 individual channel samples (≈1 m each) collected from 11 channels across the stripped area.
-
Historical context: Prior high‑grade intercepts at Argus North include 69.6 m @ 3.4 g/t Au (hole MC24‑163) and multiple >5 g/t Au intervals reported earlier in 2025.
-
Geology: High‑grade subintervals associated with strong albitization, silicification, pyritic stringers, and localized porphyritic intrusions within variolitic basalt and volcanic breccias; mineralization traced from surface to >350 m depth and remains open along strike, down‑dip, and down‑plunge.
-
Financing status: Recent closing of a $20 M bought‑deal financing; pending close of an upsized $6.4 M non‑brokered financing with strategic investors, ensuring funding through 2026 for continued exploration.
Notable Quotes
“Argus North continues to deliver wide intervals of gold mineralization right from surface… a rare and highly attractive combination in the Timmins camp,” said Brock Colterjohn, President & CEO.
“With the majority of assays from our fully funded 25,000‑metre program still pending, we are steadily building a clearer picture of the opportunity.”
