Vancouver, British Columbia--(Newsfile Corp. - July 10, 2025) - Sonoran Desert Copper Corporation (TSXV: SDCU) ("SDCU'' or the "Company") is pleased to announce that the Company has identified potential copper mineralization on its newly acquired Jucurutu Project in the State of Rio Grande do Norte, Brazil (Figure 1). The Jucurutu Project covers eleven Permit Applications with a total of 20,710.38 hectares all staked directly by the Company (Table 1).

The processing of public airborne geophysical data (gammaspectrometry and magnetometry) indicates favourable zones for copper mineralization and defined a new target that will be checked once the final applications are granted. The vertical derivative of the magnetic field showed strong structures SW-NE and SE-NW and the gamaspectrometric F-Factor indicated the presence of potential hydrothermal alteration associated with these structures (Figure 2).

The inversion model based on the magnetometry survey indicated that the structure is developing vertically in depth along the major structures observed at surface with malachite mineralization (Figure 3).
