• New drilling confirms mineralization 500 ft (152 m) to the west of ECP-045 (595 ft @ 1.29% CuT) and 700 ft (213 m) to the west of ECP-042 (86 ft @ 2.26% CuT, 0.020% Mo - Feb 10, 2022)

Arizona Sonoran Copper Company Inc. (TSX:ASCU | OTCQX:ASCUF) (“ASCU” or the “Company”), an emerging US-based copper developer and near-term producer, today released an additional 2 drill holes (4,725 ft | 1,440 m) from a 12-hole program at the Parks/Salyer (“P/S”) Project, of which six holes have now been reported. Assay results from this most recent drilling extend known mineralization a minimum of 500 ft west of prior drilling (see FIGURES 1-4). The initial drill program comprises 24,000 ft (~7300 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 and within the newly defined Exploration Target Area.

Highlights:

- ECP-057 - 199.4 ft @ 0.86% CuT, 0.81% TSol, 0.033% Mo – Oxides

  • Incl. 102.0 ft @ 1.04% CuT, 0.97% TSol, 0.028% Mo – Oxides
  • 302.0 ft @ 1.23% CuT, 1.21% TSol, 0.021% Mo – Enriched
  • Incl. 10.0 ft @ 7.95% CuT, 7.94% TSol, 0.112% Mo
  • and 75 ft @ 1.65% CuT 1.64% TSol, 0.037% Mo
  • 427.0 ft @ 0.19% CuT, 0.009% Mo – Primary

- ECP-065 - 439.7 ft @ 0.92% CuT, 0.90% TSol, 0.033% Mo – Enriched

  • Incl. 85.0 ft @ 1.43% CuT, 1.40% TSol, 0.042% Mo
  • and 137.0 ft @ 1.19% CuT, 1.17% TSol, 0.053% Mo
  • 687.7 ft @ 0.23% CuT, 0.005% Mo – Primary

Notable to both holes, which were drilled on the west side of known mineralization, was the presence of higher-grade molybdenum results in both the oxide and enriched mineralization zones. Both holes support mineralization remaining open in all directions. According to a 2019 ionic soil survey, which did not delimit the extents of the system, mineralization is open to the northwest for at least another 1,970 ft (600 m). Anomalous copper values from the ionic sampling (FIGURE 5) outline a northeast geochemical trend that parallels early successful drilling. A separate northwest trend is similarly defined by higher copper values and is being tested by current drilling. Similar patterns were outlined by molybdenum, gold and silver. Samples were collected on 328 ft (100 m) centers over the 160-acre parcel.

George Ogilvie, Arizona Sonoran President and CEO stated, “Parks/Salyer exploration results continue to support our preliminary large-scale exploration target with Cactus East-style porphyry copper. While the target is running on a northeasterly trend towards the Cactus Mine, these results push the mineralization a significant distance to the west. We continue to note the high-grade nature of leachable oxide and enriched style mineralization within intercepts spanning hundreds of feet. These results support the Exploration Target thesis to deliver significant scale to the Cactus Preliminary Economic Assessment mine plan. It remains our intent to issue a maiden mineral resource on our Parks/Salyer discovery within the Cactus Feasibility Study.”

Parks/Salyer Exploration Target

The holes drilled to date on the P/S Project continue to support the Exploration Target (see PR dated February 10, 2022 for details and cautionary language). On a preliminary basis, drilling is demonstrating a scalable underground opportunity to further expand the leachable inventory at Cactus. The total underground exploration target (the “Exploration Target”) 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% CuT for 0.15-0.75 B lbs of contained copper

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 1-4). Exploration drilling to date has been undertaken from the Company's southern property boundary northward along the northeasterly regional trend of known copper mineralization.

ECP-065 was drilled on the south-west side of the known Parks/Salyer intercepts to date. Drilling intercepted bedrock at 755 ft (230.1 m) with the mineralized host rock being silicified and sericitized brecciated granite. An oxide zone was intersected at 821 ft (250.2 m) with high-grade chalcocite enrichment interspersed with leaching encountered from 948 ft (289 m) to 1,360.3 ft (414.6 m), similar to other holes drilled in the south. From 1,360.3 ft (414.6 m) to 1,569.5 ft (478m) continuous chalcocite enrichment was drilled before entering low grade primary disseminated mineralization that terminated at the basement fault at 2,297.7 ft (700.3 m).

ECP-057 was drilled on the north-west side of known mineralization and encountered bedrock at 770 ft (234.6 m). Brecciated granite was the main host to mineralization with quartz monzonite porphyries present at depth and alteration transitioning from hematite to sericite down hole. A thicker oxide zone was encountered from 1,165.1 ft (355 m) with strong disseminated chalcocite mineralization intercepted between 1,504 ft (457.5 m) to 1,806 ft (550.5 m). Primary chalcopyrite mineralization continued from the base of the enrichment to the basement fault at 2,322.5 ft (708 m).

  1. Intervals are presented in core length and are drilled with vertical dip angles.
  2. Drill assays assume a mineralized cut-off grade of 0.5% CuT reflecting the potential for heap leaching in the case of Oxide and Enriched based on underground material, or in the case of Primary material using a 0.1% CuT cutoff to provide typical average grades. Holes were terminated below the basement fault.
  3. Assay results are not capped. Intercepts are aggregated within geological confines of major mineral zones.
  4. True widths are not known.

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.
