Sonoran Desert Copper Corporation (SDCU) has announced the signing of an amendment to the option to purchase a 100-per-cent interest in the Cuatro Hermanos Porphyry Copper Project (4H Project) located in Sonora, Mexico. The amendment, dated July 29th, 2024, includes updated transaction details and reduced payments and expenditures for the coming years.
Under the amendment, SDCU will make cash payments, complete work expenditures, and make mine tax payments to Minerales Y Yacimientos Mexicanos Sacramento, S.A. DE C.V. in order to obtain 100% ownership of the Cuatro Hermanos concessions. The revised payment and expenditure schedule will result in reduced capital expenditures for SDCU in 2024 and 2025, providing cost savings of $238,566 and a projected $603,640, respectively.
The Cuatro Hermanos Porphyry Copper Project comprises nine concessions in Sonora, Mexico, and features a large porphyry copper-molybdenum system. The project has surface measurements of at least four kilometers east-west by two kilometers north-south. SDCU released a recent NI 43-101 report on the project in October 2023, which reviewed historical work. The report indicated primary sulphide mineralization of chalcopyrite and molybdenite, with secondary oxide chalcocite.
Recent sampling in the 4H Project, focusing on areas with minimal historical attention, yielded promising results. Assays from grab samples returned copper grades of up to 16.25% in the South Conglomerate Zone, with an average of 1.736% copper across twenty samples. The higher-grade South Conglomerate area will be the immediate focus of percussion drilling to establish an inferred resource.
The soluble copper content in the North and South Conglomerates, along with the supergene zones in the 4H porphyry, present the potential for a significant Heap Leach & SX-EW operation. However, it is important to note that grab samples are selective by nature and may not fully represent the true grade or style of mineralization across the property.
SDCU is committed to securing, developing, and monetizing materials assets and technologies to create value for its shareholders. The company’s CEO and Director, Brian Leeners, expressed enthusiasm for the amendment and the potential of the Cuatro Hermanos Porphyry Copper Project.
