Copper One Drilling Update: Breccia Targeting for 2026 Planned Drill Holes

Copper One Resources Corp. ("Copper One" or the "Company") (CSE:CEXY | OTCID:CEXYF | FSE:IW8 |WKN: A42AGR) is pleased to provide this drilling update for MHB-37 and to outline the next planned drill holes targeting the results of the spring breccia mapping campaign at its flagship Majuba Hill Copper-Silver-Gold Project ( “Majuba Hill” ), located in Pershing County, Nevada.

Drill Hole MHB-37B Drill hole MHB-37B is in progress and has reached 1,743 feet (531 m). Drilling is scheduled to resume on July 8. Chalcopyrite, pyrite and possible sphalerite were visually observed within the ALS Formation between approximately 800 feet (243.8 m) and 1,100 feet (335.3 m). The ALS Formation is the host rock for the rhyolite porphyry intrusions.

MHB-37B is designed to drill approximately 2,500 feet (762 metres) and is intended to test AI driven modeling of geophysics combined with breccia mapping from the spring campaign to follow up on historic drill holes that intersected significant copper-silver-gold mineralization.

“Majuba Hill has entered an important new phase with drilling now underway on our initial ExploreTech AI-assisted core hole,” said David Greenway, President and CEO of Copper One. “As artificial intelligence accelerates the buildout of data centers, electrification infrastructure and next...
