ARIZONA SONORAN EXPLORATION DRILLING INTERSECTS NEAR SURFACE MINERALIZATION 2,500 FT (762 M) SOUTH OF PARKS/SALYER

Exploration drilling at Arizona Sonoran Copper Company Inc.'s MainSpring property has intersected near-surface copper mineralization from four drill holes. The southernmost MainSpring drill hole, ECM-186, was collared 2,500 feet (762 metres) south of the Parks/Salyer deposit and intersected shallow oxide mineralization at a depth of 138 ft (42 m) from surface. In comparison, Parks/Salyer mineralization begins at approximately 550 ft (176 m) at its shallowest, over a footprint of 2,000 ft by 2,500 ft. The MainSpring property is situated contiguous to the Parks/Salyer property and within Cactus project in Arizona, privately held by Arizona Sonoran.

Eight of 10 drill holes are now complete within the MainSpring exploration program announced Oct. 30, 2023. Current drilling is testing the near-surface extension of mineralization south of the Parks/Salyer deposit across the MainSpring property. Based on early drilling results, a comprehensive 2024 exploration program is being planned to discover the extents of shallow mineralization to the south and then connect the shallow mineralization to the thick high-grade zones at Parks/Salyer in the north.

Drilling highlights:

• Identified shallow mineralization at least 2,500 ft (762 m) south of the Parks/Salyer deposit;
• Near-surface mineralization begins at approximately 138 ft (42 m) in three of the southernmost drill holes, compared with approximately 550 ft (166 m) or greater in the Parks/Salyer deposit;
• ECM-190: 433 ft (132 m) at 0.34 per cent CuT (total copper), 0.31 per cent Cu TSol (total soluble copper) from 336 ft (102 m) depth (enriched);
  • Including 115 ft (35.1 m) at 0.58 per cent CuT, 0.56 per cent Cu TSol;
  • 50 ft (15.2 m) at 0.49 per cent CuT, 0.48 per cent Cu TSol;
  • Partial hole; assays related to the primary sulphides are pending.
• ECM-187: 716 ft (218 m) at 0.28 per cent CuT of continuous mineralization from 144.3 ft (44 m) depth;
  • 303.7 ft (92.6 m) at 0.35 per cent CuT, 0.32 per cent Cu TSol from 144 ft (44 m) depth (oxide);
  • Including 11.7 ft (3.6 m) at 3.39 per cent CuT, 3.29 per cent Cu TSol;
  • 20 ft (6.1 m) at 1.01 per cent CuT, 1 per cent Cu TSol;
  • 124.9 ft (38.1 m) at 0.34 per cent CuT, 0.33 per cent Cu TSol (enriched);
  • Including 34 ft (10.4 m) at 0.86 per cent CuT, 0.84 per cent Cu TSol.
• ECM-186: 570 ft (173.7 m) at 0.19 per cent CuT of near-continuous mineralization from 138 ft (42 m) depth;
• ECM-191: 317.1 ft (96.7 m) at 0.23 per cent CuT, 0.23 per cent Cu TSol from 370.4 ft (113 m) depth (enriched);
  • Including 126.6 ft (38.6 m) at 0.35 per cent CuT, 0.34 per cent Cu TSol.

George Ogilvie, Arizona Sonoran president and chief executive officer, commented: "Assay results coming from the MainSpring property reinforces the strength of our Cactus porphyry copper system and the significance of the Parks/Salyer deposit to the overall Cactus project. The property continues to demonstrate growth opportunities beside an already significant copper deposit within a world-class jurisdiction, on a property with a clear path to development. While these results are the first 3.5 holes from the 10-hole drilling program, we are excited about MainSpring's near-surface potential next to the deeper, high-grade Parks/Salyer deposit. We look forward to planning the expanded drill program for 2024 with a view to continue delivering value to the ASCU shareholders."

MainSpring property

Arizona Sonoran signed a purchase-sale agreement to acquire MainSpring's 523 acres in early 2023 (see Feb. 23, 2023). Situated within the Cactus project and contiguous to the Parks/Salyer deposit, the acquisition improves operational flexibility with respect to infrastructure and site requirements for the rescoped prefeasibility study expected in early Q1 2024.

Drilling recap

Eight holes totalling 9,648 feet (2,940.7 m) within the 10-hole drill program (12,550 feet/3,825.2 m) are now complete at MainSpring. Mineralization at MainSpring is interpreted to be the shallow extension of the Parks/Salyer deposit located to the north and the geological structures at MainSpring are similar to that seen at Cactus West. To date, drilling has focused on the shallow crest of a north-dipping horst block that shallows to the south and hosts oxide and enriched mineralization above primary mineralization. The north-dipping horst gently drops into graben hosting thick zones of enriched and primary mineralization that extend north to the Parks/Salyer deposit.

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 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.
