Arizona Sonoran Copper Company Inc. (TSX:ASCU |
OTCQX:ASCUF) (“ASCU” or the “Company”) reports new drill assay
results from its infill and step-out drilling program below the
previously untested extents of primary copper mineralization around
the Cactus West pit, on the Cactus Project, in Arizona. Drilling
builds upon the Company’s PEA drill database, extending the primary
sulphide zones by upwards of 500 ft (152 m) below known
mineralization (see FIGURES 1 – 10).

A total of 17 drill holes are reported herein for a total of
30,601 ft (9,387 m) of drilling, targeting the primary sulphides
below the oxide and enriched zones at Cactus West. Step-out
drilling continues with two drill rigs at Cactus West.
Drilling Highlights:
- ECW-256: 2,119* ft (646 m) @ 0.40% CuT of continuous
mineralization
- 1,896.6 ft (578 m) @ 0.41% CuT, 0.005% Mo (primary)
- ECW-258: 2,108 ft (643 m) @ 0.31% CuT of continuous
mineralization
- 2,001 ft (610 m) @ 0.31% CuT, 0.005% Mo (primary)
- ECW-260: 1,901 ft (579 m) @ 0.33% CuT of continuous
mineralization
- 1,696 ft (517 m) @ 0.33% CuT, 0.009% Mo (primary)
- ECW-266: 1,571 ft (479 m) @ 0.33% CuT of near continuous
mineralization
- 1,309 ft (399 m) @ 0.36% CuT, 0.009% Mo (primary)
- ECW-252: 1,002 ft (305 m) @ 0.40% CuT of continuous
mineralization
- 352 ft (107 m) @ 0.44% CuT, 0.41% Cu TSol, 0.014% Mo
(enriched)
- 650 ft (198 m) @ 0.37% CuT, 0.017% Mo (primary)
NOTE: True widths are not known, * includes 1.9 ft of core
loss
George Ogilvie, Arizona Sonoran President and CEO
commented, “The drill program at Cactus West is showing
significantly more primary sulphide mineralization below and
outside of the existing resource pit shell. In conjunction with
drilling at Cactus West our geological team is in the process of
preparing for an infill drilling program at Parks/Salyer,
predominantly focused on the southern claim block (MainSpring) to
move into an indicated resource ahead of a new PFS next year. As
the team’s focus is on advancing Cactus to the PFS level,
additional workstreams are ongoing, including metallurgical column
testing. New columns from the southern claim block for
Parks/Salyer, are anticipated to start in 4Q24, once new
metallurgical core has been made available.”
Drilling Recap
The 2024 Cactus West infill and exploration drill program was
designed to support the expansion of primary sulphide
mineralization down to the basement fault below the oxide and
enriched material, and laterally to extend mineralization in the
south and southwest of the known resources.
Bedrock at Cactus West is exposed approximately 150 feet to the
south-southeast of the Cactus West pit at the “Discovery Hill”. The
bedrock contact slopes away from Discovery Hill, with up to
approximately 100 ft (30 m) of alluvium cover in all directions.
Gila conglomerate lies beneath the alluvium cover and increases in
thickness to the west, east and south. Mineralized bedrock lies
directly beneath the Gila conglomerate and the depth to bedrock
extends from 0 feet at discovery hill to approximately 420 ft (128
m) at drill hole ECW-241 (PR JUN 10, 2024), 1,200 ft
(366 m) to the west.
The main lithologies at Cactus West are like those seen at
Cactus East and Parks/Salyer. Copper mineralization is hosted by
brecciated porphyritic monzonite and granite with lesser dikes
composed of porphyritic dacite and local diabase. There is
typically a thin enriched zone sitting above thick primary
mineralization. Drilling shows that copper grades increase at depth
in the primary zone in proximity to a barren potassic quartz
monzonite porphyry unit. This unit is typically 100-200 feet thick
and lies directly above the basement fault.
Drilling has extended the primary mineralization another 500ft
below and adjacent to the Cactus West open pit that was presented
in the recently issued Preliminary Economic Assessment (PR
AUG 7, 2024). Phase 2 of the primary exploration drilling,
which remains ongoing, is testing lateral stepouts from Cactus West
PEA pit shell to the north, south, and southwest.

2.
Drill assays assume a mineralized cut-off
grade of 0.1% CuT reflecting the potential for heap leaching of
open pit material in the case of Oxide and Enriched or in the case
of Primary material to provide typical average grades. Holes were
terminated below the basement fault except ECW-259 which terminated
short of the mineralized zone.
3.
Assay results are not capped. Intercepts
are aggregated within geological confines of major mineral
zones.
4.
Includes 1.9ft core loss in ECW-256, and
0.2ft missing core in ECW-258.
5.
True widths are not known.

Quality Assurance / Quality Control
Drilling completed on the project between 2020 and 2023 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 sample prep, analytical
methodologies, and quality control system complies with global
certifications for Quality ISO9001:2008.

ASCU’s objective is to become a mid-tier copper producer with
low operating costs and to develop the Cactus and Parks/Salyer
Projects that could generate robust returns for investors and
provide a long term sustainable and responsible operation for the
community and all stakeholders. The Company's principal asset is a
100% interest in the Cactus Project (former ASARCO, Sacaton mine)
which is situated on private land in an infrastructure-rich area of
Arizona. Contiguous to the Cactus Project is the Company’s
100%-owned Parks/Salyer deposit that could allow for a phased
expansion of the Cactus Mine once it becomes a producing asset. The
Company is led by an executive management team and Board which have
a long-standing track record of successful project delivery in
North America complemented by global capital markets expertise.
