Algo Grande Copper updates Adelita project technical report

Algo Grande Copper has commissioned Addison Mining Services to prepare an updated NI 43-101 technical report for its Adelita project in Sonora, Mexico. The update follows a year of project development, which has included two diamond drilling phases, aerial magnetic surveys, and extensive geological mapping since the company acquired the site in December 2025.

James Hogg, CEO of Addison Mining Services, conducted a site inspection in October to verify the project's current status and procedures. This visit fulfills the regulatory requirements for the independent qualified person responsible for the reporting process.

Adelita is situated within the Arizona-Sonora copper belt. Since acquisition, Algo Grande has defined multiple targets, including the Mezquital porphyry prospect, and secured long-term land access agreements. The company intends to file the updated report on SEDAR+ upon completion.
