Cactus East Drilling Demonstrates Consistency Of Mineralization

CASA GRANDE, AZ - Arizona Sonoran Copper Company Inc. reported on the Cactus Mine Project infill drilling program. This new set of assays continue to support the previously defined geological interpretations with thick and high-grade intercepts outlined within the underground Cactus East orebody, immediately to the northeast of the historic Sacaton pit. Infill drilling is targeting 125 ft (38 m) spacing with the goal of generating measured mineral resources.

Highlights include: Thick and high-grade intercepts are consistent with previous wider spaced drilling intercepts and resource model interpretation; ECE-067: 148.5 ft (45.3 m) @ 2.57% TCu, 2.53% Cu TSol (enriched), including 10 ft (3.0 m) @ 10.53% TCu, 10.13% Cu TSol; ECE-085: 268.0 ft (81.7 m) @ 1.51% TCu, 1.38% Cu TSol (enriched), including 203.0 ft (61.9 m) @ 1.74% TCu, 1.64% Cu TSol, and 383.3 ft (116.9 m) @ 0.51% TCu (primary); ECE-082: 226.6 ft (69.1 m) @ 1.39% TCu, 1.26% Cu TSol (enriched), including 117.7 ft (35.9 m) @ 1.88% TCu, 1.73% Cu TSol, and 379.0 ft (115.5 m) @ 0.68% TCu (primary); ECE-066: 244.8 ft (74.6 m) @ 1.26% TCu, 1.14% Cu TSol (enriched), including 142.4 ft (43.4 m) @ 1.63% TCu, 1.55% Cu TSol (oxide); ECE-062: 173.0 ft (52.7m) @ 1.60% TCu, 1.49% Cu TSol (oxide), including 100.6 ft (30.7 m) @ 2.28% TCu, 2.15% Cu TSol, and 258.0 ft (78.6 m) @ 1.01% TCu, 0.91% Cu TSol (enriched).

Ian McMullan, Chief Operating Officer, said, “Cactus East assay results continue to build upon and support the previously released assays. The high porphyry copper grades with good thicknesses underpin future mine planning and mine design work for a targeted underground bulk mining scenario at Cactus East. As previously mentioned, drills are currently focusing on Parks/Salyer to build out the known mineralization and will return later in the year to complete the measured category drilling.”

The total infill program inclusive of Cactus East and Cactus West (60,000 ft | 18,290 m) is now over halfway complete. A total of 16 HQ drill holes in the heart of the Cactus East orebody were drilled for a total of 31,817.7 ft (9,700 m). Assays are pending on 2 holes and 5 holes remain to be drilled (10,000 ft | 3,048 m). At Cactus West, 25 holes (16,000 ft | 1877 m) have been designed to infill the upper portions of the planned open pit in addition to what was previously infill drilled on the southern side of the pit . An expansionary drill program (12,000 ft | 3,660 m) is planned to follow the Cactus infill program. Due to the successful drilling results at Parks/Salyer (similar grades with greater thicknesses over a greater area), the two available drill rigs have been prioritized to that discovery. Drilling will resume on Cactus later in the year.
