ARIZONA SONORAN DRILLS 1.78% CUT OVER 639 FT (194.8 M) FROM THE PARKS/SALYER DEPOSIT

Arizona Sonoran Copper Company Inc. has drilled an initial 13 infill holes from the high-grade core of the Parks/Salyer deposit demonstrating continuity of grade and mineralized widths at 125-foot (38 metres) drill spacing. A total of 29,036 ft (8,850.2 m) have now been drilled within the overall 105,000 ft (32,000 m) infill to measured drilling program over the Cactus project deposits. This program is being undertaken to upgrade parts of the current mineral resources to the measured category for a definitive feasibility study (DFS) in late 2024.

Drilling highlights:

• Drilling replicating high grade thicknesses from prior drill programs, including five new intervals in the top 10 grade thickness intervals at Parks/Salyer;
• In July and August, two drill rigs focused in the eastern section, interpreted to be the high-grade core of the deposit;
• ECP-145: 937 ft (285.8 m) at 1.41 per cent CuT (total copper) of continuous mineralization:
  • 639 ft (194.8 m) at 1.78 per cent CuT, 1.37 per cent Cu TSol (total soluble copper), 0.016 per cent Mo (molybdenum) (enriched);
  • Including 78 ft (23.8 m) at 4.10 per cent CuT, 2.96 per cent Cu TSol, 0.013 per cent Mo;
• ECP-147: 1,023 ft (312 m) at 1.05 per cent CuT of continuous mineralization:
  • 935 ft (285.2 m) at 1.02 per cent CuT, 0.63 per cent Cu TSol, 0.014 per cent Mo (enriched);
  • Including 202 ft (61.6 m) at 2.03 per cent CuT, 1.28 per cent Cu TSol, 0.016 per cent Mo;
• ECP-162: 1,132 ft (344.9 m) at 1.23 per cent CuT of continuous mineralization:
  • 597 ft (181.8 m) at 1.49 per cent CuT, 1.44 per cent Cu TSol, 0.019 per cent Mo (enriched);
  • 170 ft (51.8 m) at 1.92 per cent CuT, 1.88 per cent Cu TSol, 0.023 per cent Mo;
• ECP-169: 880.2 ft (268.3 m) at 1.13 per cent CuT of continuous mineralization:
  • 519 ft (158.2 m) at 1.49 per cent CuT, 1.09 per cent Cu TSol, 0.011 per cent Mo (enriched);
  • Including 158 ft (48.2 m) at 2.16 per cent CuT, 2.10 per cent Cu TSol, 0.004 per cent Mo;
• ECP-152: 1,011 ft (308.2 m) at 0.78 per cent CuT of continuous mineralization:
  • 674 ft (205.6 m) at 1 per cent CuT, 0.94 per cent Cu TSol, 0.020 per cent Mo (enriched);
  • Including 125 ft (38.3 m) at 2.18 per cent CuT, 2.13 per cent Cu TSol, 0.017 per cent Mo.

Note: True widths are not known, see press release dated Sept. 28, 2022, for the P/S mineral resource

George Ogilvie, Arizona Sonoran president and chief executive officer, commented: "The team continues to execute and deliver solid results as we advance our Cactus and Parks/Salyer projects. The proven continuity of the Parks/Salyer mineralization within the deposit continues to support our vision of a top-tier asset within a Tier 1 jurisdiction. Additionally, with the recent option of MainSpring, the Parks/Salyer southern extension, we see a tremendous opportunity to continue building the Parks/Salyer mineral resource beyond the current 2.9 billion pounds at 1.015 per cent total copper inferred resource."

Drilling recap

A total of 26 infill-to-measured core holes (of a planned 47-hole program) have been drilled at 125 ft (38 m) drill centres in the eastern half of the Parks/Salyer mineral resource area since April 1, 2023. The company continues to focus on defining the high-grade core of the mineral resource, with encouraging and consistent intervals of mineralization as the geological team continues to work toward completing the drilling that will be needed for a measured resource for the definitive feasibility study in 2024. Holes ECP-145 and ECP-162 demonstrate the overall continuity of width and grade predicted by the earlier 250 ft (76 m) infill-to-indicated drill program, especially in the centre of the previously defined thicker areas of higher-grade copper, where both thickness and average grades continue to be defined by the latest infill drilling. Completed drilling that is pending results will help to further define the characteristics and boundaries of these two high-grade centres of mineralization.

Quality assurance/quality control

Drilling completed on the project between 2020 and 2022 was supervised by on-site Arizona Sonoran 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, Ariz., for analysis. Skyline's quality control system complies with global certifications for quality ISO9001:2008.

About Arizona Sonoran Copper Company Inc,

Arizona Sonoran'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-per-cent 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-per-cent-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 record of successful project delivery in North America complemented by global capital markets expertise.

We seek Safe Harbor.
