ARIZONA SONORAN DRILLS 1.97% CUT OVER 540 FT (164.6 M) AT PARKS/SALYER AND BEGINS DRILLING SOUTH OF THE PARKS/SALYER DEPOSIT

Arizona Sonoran Copper Company Inc. has released drill assays from five holes at Cactus East and four from Parks/Salyer (18,467 feet/5,629 metres). Drilling at 125 ft (38 m) drill spacings demonstrating the continuity and thicknesses of mineralization within the proposed Cactus East and Parks/Salyer high-grade underground oxide and enriched mineralized zones.

Additionally, the company has begun exploratory drilling at the MainSpring property (Parks/Salyer South), with five holes now complete. The program consists of up to 10 drill holes, targeting shallow mineralization 1,500 ft (approximately 450 m) south of the Parks/Salyer deposit. The Parks/Salyer deposit contains 143.9 million tonnes at 1.009 per cent copper measured and indicated and 48.4 Mt at 0.967 per cent Cu inferred (press release Oct. 16, 2023) and remains open to the south onto the MainSpring property. Historic Asarco drilling supports the continuity of gradually shallower mineralization toward the south, which Arizona Sonoran is testing via the current drill program.

Drilling highlights:

• Drilling:
  • Exploration: Up to 10 drill holes targeting mineralization 1,500 ft (457 m) south of the Parks/Salyer deposit at MainSpring;

George Ogilvie, Arizona Sonoran president and chief executive officer, commented: "At Cactus, the team continues to derisk the asset and drive project development forward on all fronts while concurrently reducing drill spacing to support feasibility-level requirements. In addition, one drill is now focused on the extension of Parks/Salyer mineralization to the south. Earlier this year, we strategically optioned to acquire the MainSpring (Parks/Salyer South) property. The option agreement gains access to the southern extension of our 1-plus per cent Cu Parks/Salyer deposit, where our goal is to not only grow the resource but also confirm near-surface mineralization as drilling moves south, as seen by historical drilling results."

Drilling recap

A total of 106,815.9 ft (32,557.5 m) over 51 holes, from the Cactus East and Parks/Salyer infill-to-measured drilling programs, have been reported this year. The geological team continues to work toward completing the drilling needed for measured resources for the definitive feasibility study planned for 2024. Drilling continues Arizona Sonoran's focus on defining the high-grade cores of the Cactus East and Parks/Salyer orebodies with encouraging and consistent intervals of mineralization. Holes ECE-143 and ECE-146 support the continuity of width and grade indicated by the earlier 250 ft (76 m) infill-to-indicated drill program, especially the high-grade oxide cap that overlies the enrichment blanket that forms the heart of the orebody. Holes ECE-182 and ECE-183 were drilled at the extreme northeast end of the Cactus East to extend thick oxide mineralization encountered earlier in the indicated drilling program toward the bounding East fault. These holes did encounter enriched and higher-grade primary mineralization below the fault, but the thickness of mineralization was terminated by the fault.

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 quality control system complies 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 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.
