Overview
The Cactus Project is 100% owned by Arizona Sonoran and is situated on private land in Pinal County, Arizona, the US’s leading copper-producing state.
The Sacaton Open Pit mine in the North-Eastern portion of the royalty area produced 200,000 short tons of copper and 27,455 ounces of gold during operation. The unmined Cactus East and Cactus West deposits lie either side of the Sacaton pit; and the Parks/Salyer deposit, less than 2km to the southwest, is a similar, larger deposit, exhibiting outstanding grade continuity.
The orebodies at Cactus are parts of a large, dismembered porphyry copper deposit that has undergone multiple periods of oxidation and leaching, producing a sequence of supergene enrichment. Drilling has also confirmed the presence of significant quantities of primary sulphide underlying the oxide layer.
Arizona Sonoran released an updated Mineral Resource Estimate in September 2025, and announced a subsequent Pre-Feasibility Study in October 2025, detailing production of approximately 103ktpa of estimated average annual copper cathodes over the first 10 years of mining.
