Arizona Sonoran Drills 479 ft of 1.32 % CuT from Parks/Salyer and Announces an 80,000 ft (24,400 m) Drilling Program

23.06.2022  |  Business Wire

Arizona Sonoran Copper Company Inc. (TSX:ASCU) ("ASCU" or the "Company"), an emerging US-based copper developer and near-term producer, announces an additional 3 drill holes (6,440 feet | 1,960 metres) from its initial 12-hole exploration program at the Parks/Salyer ("P/S") Project, while a new 80,000 ft (24,400 m) program is well-underway at the P/S Project (see FIGURES 1-3). The new drilling program tests the extents of the previously defined Exploration Target (see PR dated Feb 10, 22), from the southern border of P/S and in a north-eastern trend towards the Cactus Mine, at 500 ft centres. Assays are pending on an additional 12 holes.

Highlights:

  • Drilling supports the upper end of the Exploration Target's volumetric calculation below, currently defined to at least 1,500 ft by 2,000 ft and within 2 km from the Cactus Mine.
    • 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
    • ECP-079 together with ECP-061, confirms east-west continuity for 1,500 ft width. ECP-086 and ECP-092 logging results suggest an additional 1,000 ft of mineralization to the east for a potential width of 2,500 ft.
  • ECP-79 - 479 ft @ 1.32% CuT, 0.90% TSol, 0.017% Mo (enriched)
    • and 225 ft @ 0.96% CuT, 0.63% TSol, 0.039% Mo - Primary (cut off by Basement Fault)
  • ECP-61 - 474 ft @ 0.89% CuT, 0.83% TSol, 0.026% Mo - (enriched)
    • and 690 ft @ 0.33% CuT, 0.011% Mo - Primary
  • ECP-68 - 324 ft @ 1.10% CuT, 0.96% TSol, 0.005% Mo - (enriched)
    • and 753 ft @ 0.63% CuT, 0.016% Mo - Primary
    • ECP-068 shows a thickening to the southeast of grades previously intersected in historic hole S-200

George Ogilvie, Arizona Sonoran President and CEO commented, "We are thrilled with the strength of copper grades and thicknesses at the P/S Project. As a result, the assays are pointing to the higher ends of the Exploration Target. With drilling on track to be complete by mid-July, the team should have a handle on the mineral resource potential at the P/S Project, as well as the Phase 1 modelling results of the NutonTM Technology metallurgical testing.

He continued, "Looking beyond our Cactus and P/S Property, the prolific Santa Cruz copper district has seen significantly activity in the past six months and our team is excited to be a leader in the redevelopment of the world class district."

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 1-3). Exploration drilling to date has been undertaken from the Company's southern property boundary northward along the northeasterly regional trend of known copper mineralization. Enriched mineralization has been consistently flat lying, extending through all holes drilled in this round of step out drilling, including another 500 ft west and 1,000 ft east of holes with assays reported so far. Primary mineralization is persistent at depth with thickness increasing to the northwest, consistently cut off by the Basement Fault.

  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.
