Arizona Sonoran Appoints Bernie Loyer as Senior VP, Projects and Christopher White as Chief Geologist

Arizona Sonoran Copper Company Inc. (TSX:ASCU | OTCQX:ASCUF) ("ASCU" or the "Company"), an emerging copper developer and near-term producer, continues to build the development and production team onsite at the Cactus Mine Project. The Company has appointed Harold (Bernie) Loyer as Senior VP Projects, replacing Ian McMullan as Chief Operating Officer and Christopher White as Chief Geologist to support Doug Bowden, VP Exploration. Ian McMullan will be staying with the Company for up to six weeks to assist with the transition of his duties.

George Ogilvie, Arizona Sonoran President and CEO commented, "As the development of Parks/Salyer and the Cactus Mine Project progress towards PFS in Q1 2024, we have been focused on building a locally-based technical operations and development team, with the appointments of Victor Moraila (Chief Mine Engineer), Graeme Hendricks (Senior Mine Engineer), Dan Johnson (Projects Director), Greg Phillips (Project Superintendent), John Peterson (Senior Environmental Professional) and now Bernie and Christopher. With the substantial growth to the size and scale of our Cactus Mine Project, the building blocks are in place to deliver a clear and streamlined path to construction and development, pending decision post-Feasibility Study in late 2024. Bernie's experiences building complex mining projects, including BHP's Escondida and Torex Gold's, Morelos and Media Luna, will fare well with our two proposed underground projects and one open pit project at Cactus and Parks/Salyer, while Christopher's mine geology experience with major mining projects will complement our current management team."

Ogilvie continued, "I would like to thank Ian for his invaluable contribution over the last several years, placing the Company on a solid foundation and primed for future successes. The Board, ASCU team and I wish Ian well with his future endeavors and appreciate him working with the new incumbent Bernie through a transitionary period."
