Arizona Sonoran Copper Company Inc. reported additional drill assay results from the Cactus West and Cactus East deposits within the Cactus Project, Arizona. A total of 9 drill holes were completed for a total of 18,215 ft (5,552 m) supporting the 125 ft (38 m) infillto-measured and geotechnical drilling programs. Thick and high-grade total copper ("CuT") and soluble copper ("Cu TSol") intervals within this Cactus East measured drilling (125 ft | 38 m drill centres) remains consistent with indicated drilling results from the 2023 updated mineral resource. At Cactus West, infill and geotechnical drilling returned wide intervals of primary copper mineralization both below and at the extents of the Cactus West mineral resource shell.

The encouraging results support the need for an expanded Cactus West infill and exploration drill program as per the Nuton LLC Joint Venture press release. ASCU is currently finalizing the 2024 work plan, which will include follow up drilling at Cactus West and MainSpring, and metallurgical test work for the Nuton Case Integrated Pre-feasibility Study. The Nuton case PFS will build upon ASCU's Standalone PFS expected in first quarter 2024.

The third hole (ECE-185) was drilled to test the northern extent of mineralization of the main Cactus East deposit along an interpreted fault-controlled bedrock ridge. This drillhole successfully intercepted a thick zone of moderate grade oxide mineralization before entering enriched and primary sulphides. Cactus West: Six angled core holes from the proposed infill-to-measured drill program were drilled around the perimeter of the Cactus West Pit in support of our geotechnical program for proposed expansion of the pit in the mine plan.

These holes were targeted specifically to provide geotechnical information, in addition to infill drilling toward measured leachable resources at Cactus West. Their locations also provided the opportunity to test primary mineralization at depth which had not been the focus of previous drilling programs. In addition to the known resource mineralization, hole ECW-150 intercepted an additional 674.2 ft (205 m) of primary mineralization grading 0.4% CuT, within the total interval of 1,174.2 ft (358 m) @ 0.43% CuT.
