ARIZONA SONORAN PROVIDES UPDATE ON NUTON OPTION TO JOINT VENTURE

Following preliminary consultation, Arizona Sonoran Copper Company Inc. and Nuton LLC, a Rio Tinto venture, have mutually agreed to commence discussions in January with respect to an amicable early termination of the option-to-joint-venture agreement on the Cactus project.

The company will continue to advance its Cactus project on a stand-alone basis. Following from the recently completed positive stand-alone prefeasibility study, the company will continue to progress the stand-alone definitive feasibility study on the Cactus project, targeted for completion in the second half of 2026, with a view to an eventual final investment decision as early as Q4 2026, alongside its continuing advancement of related permitting amendments, project financing work and various early development activities to be defined and actioned in the new year.

The company does not intend to provide any further updates regarding its discussions with Nuton until there is a definitive update. There is no certainty as to how long such negotiations will take or that any definitive outcome will result or that any such or other outcome will be on terms mutually satisfactory to the parties.
