Arizona Sonoran Copper Company Inc. reported the first 16 drill holes (19,219 ft | 5,858 m) from an infill drilling program at MainSpring, within the 100%-owned Cactus Project in Arizona. Drilling is infilling the shallow mineralization to the southern end of the area, in support of a potential open pit design. An open pit design using the inferred category resources is being evaluated for inclusion within the pending Preliminary Economic Assessment ("PEA"), expected in Third Quarter 2024.

The MainSpring infill drill program is reducing drill spacings from 500 ft (152 m) to 250 ft (76 m) to upgrade the pending MainSpring mineral resource classification from inferred to an indicated category, funded by the Company. Additionally, the Geology team is concurrently conducting an inferred drill program at Cactus West. The Cactus West program is focused on expanding the known primary sulphide mineral resource and funded by Nuton Technologies, as part of the Option to Joint Venture agreement announced December 14, 2023.

The Integrated Preliminary Economic Study is on track and on budget for completion in Third quarter 2024. The study will explore two mining scenarios which will assume the same inputs utilized within the February 2024 Pre-Feasibility Study (?PFS?). The purpose is to demonstrate the economic potential of MainSpring, and a first look at the potential economic uplift from Nuton Technologies.

The two scenarios will be outlined as: Scenario 1: Oxides and Enriched Material from Cactus West, Cactus East, Parks/Salyer, MainSpring and the Stockpile, Scenario 2: Scenario 1, and the inclusion of primary sulphides from all sources of material, using the Nuton leaching technologies. The indicated drilling at MainSpring began immediately following the completion of the inferred drilling program and is in-filling the 500 ft (152 m) spaced holes to 250 ft (76 m). Drilling began where mineralization is closest to surface (as shallow as 140 ft | 43 m) to define an indicated shallow starter pit.

The inferred drilling shows that copper grades increase, and mineralization thickens to the north and northwest into the gap between MainSpring and Parks/Salyer, additionally depth to bedrock also increases to the north and northwest. Infill drilling is expected to continue to the north and northwest to push the potential starter pit in those directions. The lower copper grades at MainSpring are expected and coincide with remnant enriched, oxide and primary mineralization within predominantly leach cap.

Copper grades, mineralization thickness and mineralization continuity are all expected to increase north and west from MainSpring into the gap zone.
