East Drilling Illustrates Continuity Of Grade and Thickness At Cactus Mine Project

CASA GRANDE, AZ - Arizona Sonoran Copper Company Inc. (ASCU) reported on 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) centers to generate measured mineral resources. 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).

George Ogilvie, President and CEO, said, “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 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.
