Arizona Sonoran Parks/Salyer Exploration Drilling Intercepts 531 ft of 1.10% TCu

Arizona Sonoran Copper Company Inc. (TSX:ASCU | OTCQX:ASCUF) ("ASCU" or the "Company") today releases assays from 9 drill holes from the 14-hole expanded exploration program at Parks/Salyer ("P/S"), located ~1.3 mi (2 km) southwest of the Company's Cactus Mine Project. Drilling extended mineralization east by up to 1,000 ft (300 m) onto the Bronco Creek ("BCE") land, a part of the P/S Project which was acquired earlier this year (see PR dated Feb 10, 2022). Assays are pending on 4 holes (see FIGURES 1-6). The Company is also extending its current ionic leach sampling survey northeast of P/S, as well as eastward onto the BCE land.

Highlights:

• Two active drill rigs, a third rig to begin drilling metallurgical holes late September
• Maiden mineral resource on P/S in Q4 2022
• ECP-084: 531.4 ft (162.0 m) @ 1.10% TCu, 0.98% Cu TSol, 0.012% Mo (enriched)
  • Incl. 247.0 ft (75.3 m) @ 1.45% TCu, 1.35% Cu TSol, 0.014% Mo
  • And 354.0 ft (107.9 m) @ 0.65% TCu, 0.018% Mo (primary)
• ECP-086: 224.0 ft (68.3 m) @ 2.24% TCu, 2.19% Cu TSol, 0.010% Mo (enriched)
  • Incl. 114.0 ft (34.7 m) @ 2.63% TCu, 2.60% Cu TSol, 0.011% Mo
• ECP-090: 474.0 ft (144.5 m) @ 0.82% TCu, 0.73% Cu TSol, 0.007% Mo (enriched)
  • And 482.0 ft (146.9 m) @ 0.42% TCu, 0.011% Mo (primary)
• ECP-092: 216.8 ft (66.1 m) @ 1.41% TCu, 1.35% Cu TSol, 0.005% Mo (enriched)
  • Incl. 97.0 ft (29.6 m) @ 2.29% TCu, 2.20% Cu TSol, 0.004% Mo

George Ogilvie, Arizona Sonoran President and CEO commented, "These results continue to demonstrate the potential of Parks/Salyer to underpin and augment the multi-billion-pound Cactus copper project located only 1.3 miles (2 km) to the northeast. These drill holes extend mineralization from the eastern Parks/Salyer border onto the new Bronco Creek land by upwards of 1,000 ft (300 m). With drill spacing now at 500 ft (150 m) centres, we have defined the general eastern horst block extent, with assays pending on the west side for 4 holes. The team has now moved on to a 250 ft (75 m) infill drilling program to increase the confidence of the mineralization to an indicated resource category. Our goal is to issue a maiden inferred mineral resource estimate on Park/Salyer within Q4 2022."

Drilling Program Recap
Assay results are pending on 4 holes from the 14-hole expanded exploration drill program, whose goal is to extend mineralization to the west and east of the original Exploration Target. Mineralization is open locally to the north and west, with the eastern extents generally known. To focus resources, the Company is now well-underway with the infill to 250 ft (75 m) centre drilling program. Since starting the program on July 17, 2022, 5 holes are now completed for a total of 11,345 ft (3,458 m), with assays pending. A third rig is scheduled to start drilling a 3-hole metallurgical program at Parks/Salyer in late-September.

Assay results from the 26-hole exploration program are split between the following press releases, with ECP-081 being added to the initial 12 exploration program results.

13 holes: August 23, 2022, June 23, 2022, April 5, 2022, February 10, 2022
9 holes (4 assays pending): September 7, 2022.

Bronco Creek Land
In February, Cactus 110 LLC (a wholly owned subsidiary of ASCU) announced an assignment & assumption agreement and a royalty agreement in respect of acquiring 158 acres of State Land. The parcel transfer was acquired from Bronco Creek Exploration Inc., a wholly owned subsidiary of EMX Royalty Corp. (NYSE American: EMX; TSX-V: EMX). Permitting activities will be directed to the State and County levels in a similar process to owning Private Land.

TABLE 1: Drilling Highlights

1. Intervals are presented in core length and are drilled with very near vertical 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 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.

Quality Assurance / Quality Control
Drilling completed on the project between 2020 and 2022 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 quality control system complies with global certifications for Quality ISO9001:2008.
