Arizona Sonoran Cactus East Drilling Illustrates Continuity of Grade and Thickness, Drills 270 ft of 1.77% TCu
30 August 2022 - 08:30PM
Business Wire
Arizona Sonoran Copper Company Inc. (TSX:ASCU |
OTCQX:ASCUF) (“ASCU” or the “Company”) releases an additional 7
drill holes from the Cactus East, Cactus Mine Project infill
drilling program. The current drill program is designed at 125 ft
(38 m) centres to generate measured mineral resources (see
FIGURES 1-7). These results
support the previously defined thick and high-grade intercepts
outlined within the underground Cactus East resource. Cactus East
is located, at depth, immediately to the northeast of the historic
Sacaton pit.

Inclusive of both Cactus East and Cactus West, the drilling
program (60,000 ft | 18,290 m) from infill to measured is now
halfway complete. A total of 16 HQ drill holes (31,817.7 ft | 9,700
m) have been drilled into the core of the Cactus East orebody, with
assays pending on 9 holes. Due to the success of exploration at
Parks/Salyer, with similar grades and greater thicknesses than
Cactus East, the two available drill rigs have been prioritized to
drilling the 500 ft spaced Exploration Target program at
Parks/Salyer. Drilling to complete the infill drilling program at
Cactus will resume later in the year as well as an expansionary
drill program (12,000 ft | 3,660 m).
Highlights:
- Thick and high-grade intercepts consistent with the previous
wider spaced drilling intercepts and resource model interpretation
have been intercepted
- ECE-072: 270.4 ft (82.4 m) @ 1.77% TCu, 1.66% Cu TSol
(enriched)
- Incl. 100.0 ft (30.5 m) @ 3.45% TCu, 3.36% Cu TSol
- ECE-069: 247.0 ft (75.3 m) @ 1.73% TCu, 1.63% Cu TSol
(oxide)
- Incl. 90 ft. (27.4 m) @ 2.99% TCu, 2.80% Cu TSol
- And. 388 ft (118 m) @ 1.24% TCu, 1.13% Cu TSol
(enriched)
- Incl. 127 ft. (38.7 m) @ 1.91% TCu, 1.72% Cu TSol
- ECE-073: 344.0 ft (104.9 m) @ 1.07% TCu, 0.82% Cu TSol
(enriched)
- Incl. 101.7 ft (31.0 m) @1.95% TCu, 1.89% Cu TSol
- ECE-058: 120.0 ft (36.6 m) @ 2.01% TCu, 1.96% Cu TSol
(oxide)
- And 210.0 ft (64 m) @ 1.05% TCu, 0.76% Cu TSol
(enriched)
- ECE-063: 317.0 ft (96.6 m) @ 0.61% TCu, 0.46% Cu TSol
(oxide)
George Ogilvie, Arizona Sonoran President and CEO
commented, “These infill drill holes into the core of the
deposit are showing consistently high porphyry copper grades with
good thicknesses. Results illustrate the continuity required for an
underground bulk mining scenario at Cactus East that will be
contemplated in the impending PFS. Future work at Cactus East will
be supported by the improved drill density to the measured
category, including advanced technical studies.”
Drilling Program Recap Drilling completed to date focused
on further definition of the northeast trending high-grade core of
Cactus East, demonstrating continuity of grade and thickness of
oxide and enriched mineralized zones in the core area. Cactus East
infill drilling results are consistent with previously drilled
results and show thick, high-grade intercepts of both oxide and
enriched mineralization. The mineralization shows similar grade and
mineralization characteristics to Parks/Salyer, although it is
contained within a more restricted horst fault block structure.
These intercepts, and their spatial continuity, continue to support
the previous resource model and will provide valuable infill data
with tighter spacing, for more localized mine design work and
overall mine planning.
As shown in Table 1, holes ECE-058 and ECE-069 show solid
intercepts of higher-grade oxide mineralization adjacent to
historic hole S-37 while adjacent holes from this program show
continuity of thickness and grade in the underlying enriched zone
over 750 ft (230 m) of strike. ECE-069, averaging over 1.30%
CuTSol, has a combined ore zone thickness of 635 ft (200 m). This
is comparable to holes reported recently (February 10, 2022 PR) at
Parks/Salyer. Drill holes with pending assay results test
extensions of this reported mineralization to the northwest and
southeast.

1.
Intervals are presented in core length and
are drilled with vertical or near 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, or in the case of Primary material 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.

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, develop the Cactus Project 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 the Company is also exploring on
its 100% owned Park Salyer property 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.
