Cactus

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, broken up, 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 July 2024, and a subsequent Preliminary Economic Assessment in August 2024, detailing an 116kstpa operation over the first 20 years of a 31 year mine life. The studies demonstrate the newly defined Parks/Salyer deposit as being amenable to open pit mining, highlighting increased technical executability and a significant increase in metal attributable to Elemental Altus’ Royalty Area.

*The right to buy-down 0.14% of the royalty expires July 10, 2025.
