CASA GRANDE, Ariz. & TORONTO--(BUSINESS WIRE)--$ASCU #TSX--Arizona Sonoran Copper Company Inc. (TSX:ASCU) (“ASCU” or the “Company”), an emerging US-based copper developer and near-term producer, is pleased to announce assay results from the first 2 drill holes in a 12-hole program at the P/S Project. Drill hole ECP-045 extends and improves known mineralization to the northeast by 600 ft (183 m) and to within 150 ft (45 m) of the recently leased land (as noted below). Mineralization is expected to strengthen as it continues along the mine trend and into the newly leased area. Strike of the P/S Project mineralized system now totals at least 1,900 ft (579 m) with a strong grade profile (see FIGURES 1-7).

Additionally, ASCU has entered into an agreement to lease 158 acres of State Lands between the immediate boundaries of the Cactus Project and Parks/Salyer. The total land position of the combined Cactus and the P/S Project now totals 4,846 acres and provides continuity of the entire 2.5 mi (4 km) mine trend extending from Parks/Salyer to the NE Extension (see FIGURE 7).

George Ogilvie, Arizona Sonoran President and CEO stated, “These exciting drill results represent only some of the large-scale exploration upside outside of the Cactus Project. We note the drill results at P/S illustrate a very similar footprint to Cactus East, with grades in excess of 1% and good thicknesses. In particular, the drilling is demonstrating a system which is strengthening to the north and northeast towards Cactus along the mine trend. The Exploration Target at P/S is focused on extending mine life and building scalability of leachable material at the Cactus Project. Concurrent with the Cactus Feasibility drilling, our team will continue to drill the P/S Project with the aim of declaring maiden mineral resources at the P/S Project later this year. The team is currently running both programs with three drills onsite.

He continued, “As the drilling programs build on the district scale potential of the property, we have scope for further exploration at the NE Extension at Cactus. Current programs at Cactus, P/S and the NE Extension only focus on the leachable material, with known primary sulphide sitting below. The potential for significant primary material at the base of the Cactus pit and along the mine trend itself, remains untested and supports the continued belief in the opportunity and scalability of the Project.”

Parks/Salyer Exploration Target

The holes drilled to date on the P/S Project together with the new drilling, on a preliminary basis demonstrates a scalable underground opportunity for further expansion of leachable inventory at Cactus. The total underground exploration target (the “Exploration Target”) now represents an area of approximately 4,000 ft x 4,000 ft (1.2 km x 1.2 km) supported by magnetics, regional drilling results and ionic leach sampling previously conducted by ASCU. The Exploration Target at the P/S Project comprises:

• 40-90 M tons of potential leachable material @ 1.05%- 1.3% TSol for potential of 1.0-2.35 B lbs of contained copper
• 8-35 M tons of potential primary material @ 0.85-1.05% TCu for 0.15-0.75 B lbs of contained copper

The potential quantity and grade presented in the Exploration Target ranges are conceptual and have insufficient exploration and drill density to define a Mineral Resource. At this stage, it is uncertain if further exploration will result in the targets being delineated as a Mineral Resource. Estimates of exploration targets are not Mineral Resources and are too speculative to meet the NI 43-101 reporting standards. The methodology for preparing the Exploration Targets and a summary of supporting technical work undertaken to reach the targets can be found at the end of this announcement.

2022 P/S Exploration Program

ASCU is currently pursuing a 12-hole exploration program, following up on four historic diamond holes. The planned program totals 22,000 ft (~6,700 m) and aims to test the extension of the porphyry copper system from the southern border of its Parks/Salyer property, along the mine trend towards the Cactus Mine. With success, the Company may increase the number of drill holes on the project.

Subject to program success, the Company anticipates issuing a maiden mineral resource estimate for the property. Defined mineralization will aim to leverage the Cactus Mine’s already envisaged 18-year, low-cost operation, thus providing the Company with significant scale of production in the longer term.

Lease Assumption and Assignment Terms

Cactus 110 LLC (a group company of ASCU) has entered into an assignment & assumption agreement (the “Assignment & Assumption Agreement”) and a royalty agreement (the “Royalty Agreement”) in respect of transfer of permit 08-122116 with Bronco Creek Exploration Inc., a wholly-owned subsidiary of EMX Royalty Corporation (NYSE American: EMX; TSX-V: EMX). The total added land position is 158 acres of leased State Land.

Key terms of the Assignment & Assumption Agreement and Royalty Agreement include:

• Payment of US$5,000 on the effective date of the agreement (determined to be February 9, 2022) and further US$195,000 upon registration and transfer of the permit in the name of Cactus 110 LLC;
• Payment of US$1.5 M upon declaration of 100 Mlbs of mineral resource (as defined under NI 43-101) and further payment of US$1.5 M upon further declaration of additional 100 Mlbs of mineral resource (as defined under NI 43-101) in relation to the transferred property;
• Payment of US$50,000 annually as an advance royalty payment until commencement of commercial production. Upon commencement of commercial production 75% of the annual advance royalties shall be offset from the net smelter royalty payment as mentioned below;
• 1.5% net smelter royalty applicable to production returns generated (subject to allowable deductions) from the transferred property. ASCU has the right to purchase 1% of the net smelter royalty for US$500,000 at any time; and
• US$2 million undertaken in exploration expenditures before the first anniversary of the registration of the transfer and further US$2 million spent in exploration expenditures before the second anniversary of the registration of the transfer (total US$4 million work commitment)

The agreements also include customary terms and conditions as applicable to transactions of a similar nature.

Permitting activities will be directed to the State and County levels in a similar process to owning Private Land.

Geologic Description of Drilling Results at P/S

The Company’s 100%-owned Parks/Salyer Project is located 1.3 mi (2 km) down trend to the southwest of the Cactus Project on private land. The P/S Project is interpreted to represent a north trending horst block of porphyry copper mineralization similar in characteristics to that of Cactus West. Results to date at Parks/Salyer support that interpretation with mineral zonation also consistent with Cactus containing oxide, chalcocite enrichment, and primary chalcopyrite-molybdenite mineralization (see FIGURES 1-7). Exploration drilling to date has been undertaken from the Company's southern property boundary northward along the northeasterly regional trend of known copper mineralization. Hole ECP-042 intercepted oxide and enriched mineralization with a post mineral dacite dike truncating the continuity of the high-grade enrichment. Similar dacite dikes were encountered during the mining of the Sacaton (Cactus West) pit where they were observed as localized and discontinuous features.

Thick, continuous primary chalcopyrite-molybdenite mineralization was intercepted at depth terminating at the basement fault. ECP-045 intercepted thick, continuous oxide and enriched copper mineralization with little post-enrichment leaching. The bedrock and mineralization contacts indicate ECP-045 is located within a downfaulted block from previous holes drilled at Parks/Salyer which compliments the reduced post-enrichment leaching observed. The continuity and grade of mineralization logged in ECP-045 is similar to that intercepted in Cactus East drilling, which represents a high-grade underground resource in the Cactus Project located within a down dropped block from the shallower Cactus West mineralization. ECP-045 is the northern most hole drilled in the P/S Project and mineralization remains open in all directions. According to a 2019 ionic soil survey, which did not define the extents of the system, mineralization is open to the northwest for at least another 1,969 ft (600 m).

Summary of Information Comprising the Exploration Target

ASCU has conducted extensive exploration work to delineate the Exploration Target contained in this announcement. This work includes analysis and interpretations from four historical and the two recently drilled core holes into the project, similarities of mineralization intercepted to that of the adjacent Cactus project (for mineralization and alteration characteristics, and grade architecture), and review of geophysical and surface ionic leach programs to support realistic target ranges for extent, thickness, and grade. The Exploration Target ranges assume an underground target for exploration purposes.

Quality Assurance / Quality Control

Drilling completed on the project in 2020 and 2021 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.
