Arizona Sonoran Copper Company Inc. (TSX:ASCU) (OTCQX:ASCUF) releases assays from 3 drill holes from its 105,000 ft (32,000 m) infill to indicated drilling program at Parks/Salyer, located ~1.3 mi (2 km) southwest of the Company’s Cactus Mine Project. Infill drilling continues to intersect thick high-grade mineralization which supports the currently modelled inferred Mineral Resource at P/S (see FIGURES 1-9).
Additionally, assay results from the final 4 exploration drill holes from Parks/Salyer’s western extents are also being reported. Results from these drill holes were included in the 2.9 B lb Inferred Mineral Resource Estimate reported on September 28, 2022.
– Infill drilling to 250 ft drill spacing, in support of an initial Preliminary Feasibility Study (PFS) within 11-17 months
– ECP-098: 714.1 ft (217.7 m) @ 1.01% TCu, 0.90% Cu TSol, 0.024% Mo (enriched)
– ECP-097: 746.2 ft (227.4 m) of continuous mineralization
– ECP-099: 552.0 ft (168.2 m) @ 1.10% TCu, 0.85% Cu TSol, 0.030% Mo (enriched)
George Ogilvie, Arizona Sonoran President and CEO commented, “We continue to move forward at our Cactus and Parks/Salyer projects concurrently, with the intent of issuing a combined Prefeasibility Study in the next 11-17 months. The recently issued maiden mineral resource estimate for Parks/Salyer combined with the resource estimate at Cactus has now catapulted the combined projects to a size that would make it the 4th largest independent copper deposit in the USA with a total copper resource of 4.9 Billion lbs Inferred and 1.6 Billion lbs Indicated.
“At P/S the infill drilling to 250 ft centres is now well underway with all drilling and assaying expected to be completed in 2Q23. Further metallurgical columns on the P/S leachable mineralization is underway and are expected to run throughout 2023. Additionally, geotechnical and hydrological studies on P/S have now been initiated.
“At Cactus new metallurgical columns have begun, purposely designed for a future Bankable Feasibility Study.”
Mineral Resource and Exploration Drilling Program Recap
The final 4 holes from the expanded exploration drill program are now complete and successfully extended mineralization along the western extents of the deposit. The deposit spans an area of 3,500 ft (1,067 m) by 2,200 ft (671 m). The extents of the main high-grade core at Parks/Salyer have been defined by the completed exploration program, however exploration potential remains along the NE oriented mine trend corridor towards the Cactus West deposit. A total of 31 exploration holes spaced at ~500 ft drill spacings were included into the MRE and calculated an inferred copper resource of 2.9 billion pounds at 1.015% total Copper. The total leachable resource totals 2.45 billion pounds at 1.065% total Copper (see PR dated Sept 28, 2022). The current 105,000 ft (32,000 m) drilling program is reducing drill spacings to 250 ft, aimed at upgrading the mineral resource category to indicated in support of the potential definition of maiden reserves in the upcoming PFS.
A third rig has begun drilling a 3-hole metallurgical program at Parks/Salyer in October to support a column leach test program for P/S material ahead of the PFS. Additional updates will be provided on the metallurgical, geotechnical and hydrological programs as information is available.

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.

About Arizona Sonoran Copper Company
ASCU’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% 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%-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 track record of successful project delivery in North America complemented by global capital markets expertise.
