CASA GRANDE, Ariz. & TORONTO — Arizona Sonoran Copper Firm Inc. (TSX:ASCU | OTCQX:ASCUF) (“ASCU” or the “Firm”), an rising copper developer and near-term producer, at the moment pronounces 6 infill holes from the Parks/Salyer Pre-Feasibility Research (“PFS”) degree drilling program. The infill to Indicated drilling program was accomplished on time and throughout the price range, with the remaining assays from 10 drill holes anticipated by the center of Might. This program shall be used to generate an up to date useful resource mannequin and mine plan to help the declaration of first reserves within the pending PFS by Q1 2024. As introduced March 6, 2023, the PFS is exploring an built-in operation for Parks/Salyer and Cactus focusing on 50 ktpa manufacturing (see FIGURES 1-11).

PFS-level drilling at Parks/Salyer included geotechnical (HQ), hydrological (HQ) and metallurgical (PQ) holes, along with the infill drilling (HQ). Having accomplished the packages, the three drill rigs at the moment are targeted on the next drilling packages:

NOTE: True widths should not identified

Doug Bowden, Arizona Sonoran VP Exploration commented, “As we full drill packages to finalize an indicated useful resource estimate (PFS), help engineering and mine planning, we be aware the drilling is performing as deliberate, and in situations, with higher than anticipated grade thicknesses. Parks/Salyer intercepts point out a steady deposit with usually 100-300 meter enrichment thicknesses that would doubtlessly help a bulk mining state of affairs. Infill drilling has continued to broaden the high-grade core at Parks/Salyer throughout the inferred useful resource space outlined by the unique 500 ft (152 m) drill sample.”

Drilling Recap

A complete of three metallurgical holes (PQ – 3.345 inch diameter) had been accomplished to offer materials for the column leach testing going down onsite on the TruStone Facility. The columns at the moment are 90 and 120 days full, and preliminary outcomes are anticipated shortly. Two metallurgical holes, together with one HQ (2.5 inch diameter) drill gap, had been transformed to hydrology monitoring holes. A complete of 5 oriented core and geotechnical holes are being surveyed for fracture and directional evaluation forward of mine planning; by way of Acoustic Tele-viewer survey.

The infill to indicated drilling program was deliberate to infill to 250 ft (76 m) drill facilities, extending by way of the leachable oxides and enriched mineralization, or secondary sulphides, for inclusion as our base case mine plan. To make sure a whole view of the deposit, for ASCU data and because it pertains to the Nuton sulphide leaching applied sciences, ASCU additionally drilled by way of the first sulphides to the basement fault at Parks/Salyer defining a deposit that extends 2,900 ft (884 m) by 2,200 ft (670 m), on the south-western finish of the 4 km mine development.

Infill drilling on the west aspect of the Parks/Salyer deposit ( FIGURE 1) continues to outline the westward continuation of thick, higher-grade, enriched and first mineralization (ECP-126 and ECP-131). Drill holes ECP-134, ECP-133 and ECP-127 display continuation of the enrichment blanket to the west, albeit with thinner, stacked layers of copper mineralization which have suffered leaching close to the faults that outline the sting of the orebody. Drill holes ECP-127, ECP-130 and ECP-133 present the same definition of the enrichment blanket. A NS cross part by way of the realm demonstrates the continuity of the enrichment zone on the western fringe of Parks/Salyer and the impact of late oxidation on the enrichment blanket within the space of ECP-130.

The dacite dyke proven within the cross part is comparable in width and continuity to dacite dykes seen in Cactus West on the southern fringe of that orebody. These dykes are very late stage relative to the mineralizing occasion and acted as dams to the enrichment course of, with excellent enrichment and oxide grades ponding above them, as proven in ECP-131.

There are various occurrences of native copper across the deposit. Whereas native copper doesn’t signify a major contribution to the oxide useful resource, it does point out directional movement of the secondary copper fluids, typically pointing towards ponded enrichment areas as proven in ECP-131. The crew is at the moment mapping situations of each native copper and cuprite as they usually exist inside shut proximity of one another.

ASCU drilling has outlined the sting of a potassic zone related to decrease grades within the main mineralization within the northwest quadrant of the orebody. Greater main grades are generally related to zones of phyllic alteration (generally as an overprint), which at Parks/Salyer follows the overall mine development NE orientation. This phyllic zone represents the bigger space of thicker, greater grades proven in FIGURE 2.

High quality Assurance / High quality Management

Drilling accomplished on the venture between 2020 and 2022 was supervised by on-site ASCU personnel who ready core samples for assay and carried out a full QA/QC program utilizing blanks, requirements, and duplicates to observe analytical accuracy and precision. The samples had been sealed on website and shipped to Skyline Laboratories in Tucson AZ for evaluation. Skyline’s high quality management system complies with world certifications for High quality ISO9001:2008.

Technical elements of this information launch have been reviewed and verified by Allan Schappert – CPG #11758, who’s a certified particular person as outlined by Nationwide Instrument 43-101– Requirements of Disclosure for Mineral Initiatives.

About Arizona Sonoran Copper Firm ( www.arizonasonoran.com | www.cactusmine.com)

ASCU’s goal is to turn into a mid-tier copper producer with low working prices and to develop the Cactus and Parks/Salyer Initiatives that would generate strong returns for traders and supply a long run sustainable and accountable operation for the neighborhood and all stakeholders. The Firm’s principal asset is a 100% curiosity within the Cactus Venture (former ASARCO, Sacaton mine) which is located on personal land in an infrastructure-rich space of Arizona. Contiguous to the Cactus Venture is the Firm’s 100%-owned Parks/Salyer deposit that would permit for a phased growth of the Cactus Mine as soon as it turns into a producing asset. The Firm is led by an govt administration crew and Board which have a long-standing observe report of profitable venture supply in North America complemented by world capital markets experience.
