ARIZONA SONORAN EXTENDS MINERALIZATION 674 FT (205 M) BELOW CACTUS WEST MINERAL RESOURCE SHELL; DRILLS 731 FT (223 M) OF 0.92% CUT OF CONTINUOUS MINERALIZATION AT CACTUS EAST

Arizona Sonoran Copper Company Inc. has released additional drill assay results from the Cactus West and Cactus East deposits within the Cactus project in Arizona. A total of 9 drill holes were completed for a total of 18,215 ft (5,552 m) supporting the 125 ft (38 m) infill-to-measured and geotechnical drilling programs (see

Thick and high-grade total copper ("CuT") and soluble copper ("Cu TSol") intervals within this Cactus East measured drilling (125 ft | 38 m drill centres) remains consistent with indicated drilling results from the 2023 updated mineral resource.

At Cactus West, infill and geotechnical drilling returned wide intervals of primary copper mineralization both below and at the extents of the Cactus West mineral resource shell. The encouraging results support the need for an expanded Cactus West infill and exploration drill program as per the Nuton LLC Joint Venture press release (see PR Dec 14, 2023 ). ASCU is currently finalizing the 2024 work plan, which will include follow up drilling at Cactus West and MainSpring, and metallurgical test work for the Nuton Case Integrated Pre-feasibility Study. The Nuton case PFS will build upon ASCU's Standalone PFS expected in Q1 2024.

George Ogilvie, Arizona Sonoran President and CEO commented, "The infill to measured drilling supports the updated Mineral Resource Estimate that we released in October 2023. This measured infill drilling bodes well for future updates to the Mineral Resource Estimate (MRE) and Definitive Feasibility Studies, planned following the release of our Stand Alone PFS in 1Q24. Specific to Cactus East it was encouraging to see an extension of the leachable mineralization to the northeast, representing potential future mineral resource growth.

We were particularly intrigued by the results from Cactus West, host to the majority of the primary resources within the Cactus MRE. At Cactus West, we continued to drill primary mineralization for an additional 674 ft (205 m) below the existing pit-shell demonstrating more opportunities for future resource growth along the mine trend. Given the recent signing of the "Nuton Option to Joint Venture Agreement" and the new focus on the primary sulphides with our JV partner on a go forward basis, we anticipate unlocking additional value for the shareholders of the company."

Drilling Recap

Cactus East

Two of the three core holes drilled at Cactus East were infill-to-measure planned drillholes. The third hole (ECE-185) was drilled to test the northern extent of mineralization of the main Cactus East deposit along an interpreted fault-controlled bedrock ridge. This drillhole successfully intercepted a thick zone of moderate grade oxide mineralization before entering enriched and primary sulphides.

Cactus West

Six angled core holes from the proposed infill-to-measured drill program were drilled around the perimeter of the Cactus West Pit in support of our geotechnical program for proposed expansion of the pit in the mine plan. These holes were targeted specifically to provide geotechnical information, in addition to infill drilling toward measured leachable resources at Cactus West. Their locations also provided the opportunity to test primary mineralization at depth which had not been the focus of previous drilling programs. In addition to the known resource mineralization, hole ECW-150 intercepted an additional 674.2 ft (205 m) of primary mineralization grading 0.4 per cent CuT, within the total interval of 1,174.2 ft (358 m) of 0.43 per cent CuT.

Quality Assurance / Quality Control

Drilling completed on the project between 2020 and 2023 was supervised by on-site ASCU personnel who prepared core samples for assay and implemented a full QA/QC program using blanks, standards, and duplicates to monitor analytical accuracy and precision. The samples were sealed on site and shipped to Skyline Laboratories in Tucson AZ for analysis. Skyline's sample prep, analytical methodologies, and quality control system complies with global certifications for Quality ISO9001:2008.

About Arizona Sonoran Copper Company ( www.arizonasonoran.com | www.cactusmine.com )

ASCU's objective is to become a mid-tier copper producer with low operating costs and to develop the Cactus and Parks/Salyer Projects that could generate robust returns for investors and provide a long term sustainable and responsible operation for the community and all stakeholders. The company's principal asset is a 100% interest in the Cactus Project (former ASARCO, Sacaton mine) which is situated on private land in an infrastructure-rich area of Arizona. Contiguous to the Cactus Project is the company's 100%-owned Parks/Salyer deposit that could allow for a phased expansion of the Cactus Mine once it becomes a producing asset. The company is led by an executive management team and Board which have a long-standing track record of successful project delivery in North America complemented by global capital markets expertise.
