Arizona Sonoran Copper (TSX:ASCU) has successfully completed drilling of 13 infill holes at the Parks/Salyer deposit’s high-grade core, which displays consistency in both grade and mineralized widths at a 125 ft (38 m) drill spacing. Out of the total planned drilling for the Cactus Project deposits, 29,036 ft (8,850.2 m) has been covered, aiming to complete an overall 105,000 ft (32,000 m) by the end of the program. This extensive drill program seeks to improve the precision of the current mineral resources, setting the stage for a detailed feasibility study in 2024.
Since the beginning of April 2023, 26 out of a proposed 47-hole program have been drilled at 125 ft (38m) drill centres in the eastern section of the Parks/Salyer mineral resource area. The primary aim remains to pinpoint the high-grade core of the mineral resource, with the geological team noting steady intervals of mineralization. This effort is gearing up for a comprehensive feasibility study next year. Notably, holes ECP-145 and ECP-162 indicate a continuity of width and grade that aligns with expectations set by an earlier 250 ft (76m) drill program. This consistency is particularly evident in areas previously identified to have a thicker and higher-grade copper presence. As drilling progresses, forthcoming results are anticipated to provide more insights into the specific traits and boundaries of the two prominent high-grade mineralization centres.
George Ogilvie, Arizona Sonoran President and CEO commented in a press release: “The team continues to execute and deliver solid results as we advance our Cactus and Parks/Salyer projects. The proven continuity of the Parks/Salyer mineralization within the deposit continues to support our vision of a top tier asset within a tier 1 jurisdiction. Additionally, with the recent option of MainSpring, the Parks/Salyer southern extension, we see a tremendous opportunity to continue building the Parks/Salyer mineral resource beyond the current 2.9 billion pounds at 1.015% total copper inferred resource.”
Highlights from the results are as follows:
– Drilling replicating high-grade thicknesses from prior drill programs, including 5 new intervals in the top 10 grade thickness intervals at Parks/Salyer
– In July and August, 2 drill rigs focused in the eastern section, interpreted to be the high grade core of the deposit

1. |
Intervals are presented in core length and are drilled with vertical, or steep dip angles. |
|
|
2. |
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, 0.1% CuT, 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. |
