ASCU Arizona Sonoran Copper Company Inc

Arizona Sonoran Copper Company Inc. (TSX:ASCU | OTCQX:ASCUF) (“ASCU” or the “Company”), an emerging copper developer and near-term producer, drills initial 13 infill holes from the high grade core of the Parks/Salyer deposit demonstrating continuity of grade and mineralized widths at 125 ft (38 m) drill spacing (see FIGURES 1-15). A total of 29,036 ft (8,850.2 m) has 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 5 new intervals in the top 10 grade thickness intervals at Parks/Salyer (see FIGURE 4)

- In July and August, 2 drill rigs focused in the eastern section, interpreted to be the high grade core of the deposit

- ECP-145: 937 ft (285.8 m) @ 1.41% CuT of continuous mineralization

• 639 ft (194.8 m) @ 1.78% CuT, 1.37% Cu TSol, 0.016% Mo (enriched)
• Incl 78 ft (23.8 m) @ 4.10% CuT, 2.96% Cu TSol, 0.013% Mo

- ECP-147: 1,023 ft (312 m) @ 1.05% CuT of continuous mineralization

• 935 ft (285.2 m) @ 1.02% CuT, 0.63% Cu TSol, 0.014% Mo (enriched)
• Incl 202 ft (61.6 m) @ 2.03% CuT, 1.28% Cu TSol, 0.016% Mo

- ECP-162: 1,132 ft (344.9 m) @ 1.23% CuT of continuous mineralization

• 597 ft (181.8 m) @ 1.49% CuT, 1.44% Cu TSol, 0.019% Mo (enriched)
• And 170 ft (51.8 m) @ 1.92% CuT, 1.88% Cu TSol, 0.023% Mo

- ECP-169: 880.2 ft (268.3 m) @ 1.13% CuT of continuous mineralization

• 519 ft (158.2 m) @ 1.49% CuT, 1.09% Cu TSol, 0.011% Mo (enriched)
• Incl 158ft (48.2m) @ 2.16% CuT, 2.10% Cu TSol, 0.004% Mo

- ECP-152: 1,011 ft (308.2 m) @ 0.78% CuT of continuous mineralization

• 674 ft (205.6 m) @ 1.0% CuT, 0.94% Cu TSol, 0.020% Mo (enriched)
• Incl 125 ft (38.3 m) @ 2.18% CuT, 2.13% Cu TSol, 0.017% Mo

NOTE: True widths are not known, see PR dated September 28, 2022 for the P/S mineral resource

George Ogilvie, Arizona Sonoran President and CEO 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% 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 (38m) drill centers in the eastern half of the Parks/Salyer mineral resource area since April 1st, 2023. We continue 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. As shown in FIGURE 4, holes ECP-145 and ECP-162 demonstrate the overall continuity of width and grade predicted by the earlier 250 ft (76m) infill-to-indicated drill program, especially in the center 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 centers of mineralization.

1.

Intervals are presented in core length and are drilled with vertical, or steep dip angles.

2.

Drill assays assume a mineralized cut-off grade of 0.5% CuT reflecting the potential for heap leaching of underground material in the case of Oxide and Enriched or in the case of Primary material, 0.1% CuT, to provide typical average grades. Holes were terminated below the basement fault.

3.

Assay results are not capped. Intercepts are aggregated within geological confines of major mineral zones.

4.

True widths are not known.
