Arizona Sonoran Drills 1.43% Cu TSol Over 80.9 m

Arizona Sonoran Copper Company Inc. (TSX:ASCU) (“ASCU” or the “Company”), an emerging US-based copper developer and near-term producer, announces assays from two drill holes (1,133.5 m | 3,718.9 ft) in the Cactus East deposit as part of a 9,144 m (30,000 ft) Pre-Feasibility Study (“PFS”) infill to indicated drilling program. The drilling targeted the oxide material along the periphery of the Cactus East Preliminary Economic Assessment (“PEA”) underground mine plan, defining mineralization towards the East Fault and gathering an understanding of the geometry of the fault (see FIGURES 1-3, TABLE 1 below).

Hole ECE-021, extended mineralization 61 m (200 ft) east of the current mineral resource shell and is one the best oxide intercepts ever drilled at the Cactus Project. The drill intercept of leachable material is considerably thicker and higher grade than predicted in the area at 99.1 m (325 ft) @ 1.28% Cu TSol (total soluble) vs 48.8 m (160 ft) @ 0.54% Cu TSol. Mineralization is open 122 m (400 ft) north, towards the NW trending East Fault. Follow up drilling will be conducted to confirm the continuity of the high-grade zone to the north and east adjacent to the East fault.

Highlights:

  • The drilling demonstrates continuous leachable mineralization including extensions outwards from the mineral resource pit shell by at least 61 m (200 ft)
  • ECE-021: 1.43% Cu TSol over 80.9 m (266 ft) of oxide mineralization; incl: 2.21% Cu TSol over 27.2 m (89 ft)
  • ECE-020: 0.50% Cu TSol over 100.9 m (331 ft) of oxide mineralization

George Ogilvie, ASCU President and CEO commented, “The infill drilling to indicated mineral resource classification is a key program as we move towards the Pre-Feasibility Study, expected in mid-2022, and will underpin all future engineering work at Cactus. The initial high grade oxide results are providing improved data points for the upcoming PFS, while also confirming that grades improve towards the East fault.”

  1. Intervals are presented in core length; are drilled with vertical dip angles
  2. Drill assays assume a mineralized cut-off grade of 0.1% CuT reflecting the potential for heap leaching in the case of Oxide and Enriched material, or to provide typical average grades in the case of Primary material. ECE-020 was terminated in Primary mineralization, ECE-021 was terminated in basement rocks intercepted at 1,900ft depth.
  3. Assay results are not capped. Intercepts are aggregated within geological confines of major mineral zones.
  4. True widths are not known.

PFS Drilling Program

Current 9,144 m (30,000 ft) Pre-Feasibility Study (PFS) infill to indicated drilling program targets drill spacing of 76 m (250 ft) spacing. The drilling program infills material classified as inferred in the PEA mine plan based on the mineral resource estimate. Assays are pending for further infill drilling in Cactus West and Cactus East and drilling continues to complete the program.

A total of 265 holes for 72,255 m (237,057 ft) has now been drilled into the Cactus West and East deposit. Since 2019, ASCU have drilled 127 of those holes for 30,468 m (99,959 ft). 49 holes for 26,730 m (87,698 ft) have been drilled into Cactus East.

Geological Description

The Cactus East Orebody has long been recognized as the down-dropped eastern edge of the Cactus West Orebody, with the oxide and enriched zones preserved at 304.8 m (1,000 ft) below Cactus West, and well above the Basement Fault. Cactus East is also preserved within a series of post-mineral normal faults as a pyramid-shaped body with the oxide zone and overlying leach cap at the peak.

Currently, the Cactus East underground oxide and enriched mineral resource contains 146M lbs of copper at 0.95% TSOL in the indicated Category and 315M lbs of copper at 0.88%TSOL in the inferred category; any new drilling data will be used to support the PFS expected mid-2022.

Quality Assurance / Quality Control

Drilling completed on the project in 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.
