ARIZONA SONORAN DRILLS 521 FT (159 M) @ 1.78% CUT AT PARKS/SALYER

Arizona Sonoran Copper Company Inc. has released infill drill assay results from the Parks/Salyer infill to measured program on the Cactus project in Arizona. These 11 drill holes total 24,463 feet (7,456 metres) of drilling.

Additionally, infill and exploration drilling to the south of Parks/Salyer has resumed at MainSpring with three drills, building on the 11-hole program undertaken in late 2023. The MainSpring drill program is testing the near-surface southern extension of the Parks/Salyer deposit, which lies approximately 1,500 feet (457 metres) to the north. Assays from four of these core holes were reported in press release dated Nov. 20, 2023, while results from the remaining seven core holes are still pending.

Drilling highlights:

• ECP-178: 521 feet (159 m) of 1.78 per cent CuT (total copper), 1.61 per cent Cu TSol (total soluble copper) and 0.011 per cent Mo (molybdenum) (enriched):

George Ogilvie, president and chief executive officer of Arizona Sonoran, commented: "We look forward to integrating the thick and high-grade Parks/Salyer porphyry copper deposit into our prefeasibility study due out this quarter. Having completed the Parks/Salyer drilling in support of the indicated category and a partial program in support of the measured category for a future definitive feasibility study, we look forward to demonstrating the exploration upside of our Cactus project. In 2024, our exploration teams will expand the definition of the primary sulphides, in addition to the oxides and enriched material at our MainSpring and Cactus West projects, presenting a significant potential for the company."

Drilling recap

Infill drilling at Parks/Salyer focused on expanding the high-grade core areas on the east side of the orebody, defined by earlier infill drilling. The eastern side of Parks/Salyer hosts thick intercepts of covellite-rich mineralization that straddles the boundary between the enriched and primary zones, highlighted by the elevated total copper and soluble copper grades shown in this new drilling. As shown in the attached table, these intercepts include excellent thicknesses of higher grades in both the enriched and primary zones, which were suggested by previous drilling but are becoming better defined by additional infill drilling.

Drill holes ECP-140 and ECP-178 were drilled as oriented core holes to assist in the geotechnical evaluation of Parks/Salyer for the pending prefeasibility study.

Quality assurance/quality control

Drilling completed on the project between 2020 and 2023 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 sample prep, analytical methodologies and quality control system comply with global certifications for quality (ISO 9001:2008).

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 (formerly ASARCO's 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, which 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 that have a long-standing record of successful project delivery in North America complemented by global capital markets expertise.

We seek Safe Harbor.
