Arizona Sonoran Intersects 621 ft of 2.0% Total Copper at Parks/Salyer Infill Drilling within 872.5 ft of 1.64% CuT of Continuous Mineralization
17 January 2023 - 10:30PM
Business Wire
Arizona Sonoran Copper Company Inc. (TSX:ASCU |
OTCQX:ASCUF) (“ASCU” or the “Company”) today announces 60%
completion of its 105,000 ft (32,000 m) infill to indicated
drilling program at Parks/Salyer (“P/S"), located ~1.3 mi (2 km)
southwest of the Company’s Cactus Mine Project (see FIGURES
1-10). A total of 27 holes have now been drilled out of an
anticipated 46 holes, with assays received to date for 15 holes,
including the five reported in this release.
The program continues to support the tenor of mineralization
while reducing drill spacing from 500 ft (150 m) to 250 ft (76 m)
centres, suitable to upgrade the resource from the inferred
category to the indicated category. Drilling has been staged to
infill areas closest to the inferred high-grade core initially,
before expanding out towards the west.
Highlights:
- ECP-108 grade thickness surpasses the prior best intercept
on the property
- ECP-108: 872.5 ft (265.9 m) @ 1.64% CuT of continuous
mineralization, including:
- 621.0 ft (189.3 m) @ 2.00% CuT, 1.58% Cu TSol, 0.013% Mo
(enriched)
- Incl. 108.0 ft (32.9 m) @ 2.58% CuT, 2.45% Cu TSol, 0.009%
Mo
- 251.5 ft (76.7 m) @ 0.73% CuT, 0.019% Mo (primary)
- ECP-107: 1,188.9 ft (362.4 m) @ 0.68% CuT of continuous
mineralization, including:
- 489.5 ft (149.2 m) @ 1.19% CuT, 1.13% Cu TSol, 0.013% Mo
(enriched)
- Incl. 139.3 ft (42.5 m) @ 2.42% CuT, 2.39% Cu TSol, 0.010%
Mo
- 699.4 ft (213.2 m) @ 0.33% CuT, 0.012% Mo (primary)
- ECP-110: 762.2 ft (232.3 m) @ 0.90% CuT of continuous
mineralization, including:
- 419.0 ft (127.7 m) @ 1.15% CuT, 1.01% Cu TSol, 0.005% Mo
(enriched)
- 343.2 ft (104.6 m) @ 0.58 % CuT, 0.011% Mo (primary)
- ECP-111: 443.0 ft (135.0 m) @ 0.78% CuT, 0.71% Cu TSol,
0.035% Mo (enriched)
NOTE: True widths are not known
George Ogilvie, Arizona Sonoran President and CEO
commented, “This drilling continues to demonstrate the
consistency of copper grade and thickness, in both the leachable
and primary sulphide mineralization and within the high-grade core
of the Parks/Salyer deposit. Two drills will finish the remaining
40% of the drill program this quarter, while a third drill rig will
move to the NE Extension to conduct exploration holes. This infill
drilling will allow us to upgrade the Parks/Salyer resource from
its current inferred category to an indicated category, that can
then be fed into our re-scoped PFS in late 2023, early 2024.”
Exploration Drilling Program Recap
The current 105,000 ft (32,000 m) drilling program is reducing
drill spacings to 250 ft, aimed at upgrading the mineral resource
category to indicated in support of the potential definition of
maiden reserves in the upcoming PFS. To date the drilling of 27
infill core holes (59,289 ft | 18,071 m) has defined a high-grade
zone within the eastern half of the deposit, which is currently
being pursued westward with the remainder of the drilling, as
demonstrated by the grade/thickness map of completed drilling.
Chalcocite and covellite are the dominant copper species in the
enriched mineralization, replacing primary pyrite and chalcopyrite
in their original depositional habits, such as veins, breccia
fillings, voids and disseminations. These replacements styles,
shown in FIGURES 1-10, are representative of our
enriched mineral zone. Chalcocite also tends to build on itself,
resulting in zones of higher-grade mineralization where the
enrichment fluids had time and opportunity to continue the
secondary enrichment process.

- Intervals are presented in core length and are drilled with
very near vertical dip angles.
- Drill assays assume a mineralized cut-off grade of 0.5% CuT
reflecting the potential for heap leaching of underground 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.
- Some intercepts in the western exploration holes assumed a
mineralized cut-off grade of 0.1% CuT to provide typical average
grades of the tenor of mineralization.
- Assay results are not capped. Intercepts are aggregated within
geological confines of major mineral zones.
- True widths are not known.

Quality Assurance / Quality Control
Drilling completed on the project between 2020 and 2022 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.

About Arizona Sonoran Copper Company (www.arizonasonoran.com |
www.cactusmine.com)
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.
