Algo Grande Finalizes Phase II Drill Targets Following Completion of High-Definition Surveys

• Algo Grande Copper Corp. announced the completion of high-definition drone magnetic and Lidar surveys at its Adelita Project in Sonora, Mexico.
• The surveys expanded the Cerro Grande skarn target footprint from approximately 300 metres to a 2.5-kilometre prospective corridor.
• A Phase II diamond drill program totaling approximately 8,000 metres is scheduled to commence in June 2026.
• The program aims to double historical drilling on the property and includes maiden testing of two new district-scale targets: Cerro Potrero South (skarn) and Las Trancas (epithermal).
• An investor webinar was held on May 29, 2026, to discuss these survey results and targeting strategies.

• The news confirms the execution of a previously announced exploration strategy rather than introducing new discovery data or financing.
• Phase II drilling was anticipated following the $6.52 million financing closed in February 2026 and earthworks announcements in April 2026.
• While positive for project progression, the lack of assay results means this is a procedural update on an already funded initiative.
• The market has likely priced in the drilling program since the April announcement regarding earthworks and target refinement.
• Current share price ($0.61) trades below the recent private placement price ($0.65), suggesting limited immediate upside reaction to this specific news release compared to earlier discovery announcements.

• Company: Algo Grande Copper Corp. (TSXV: ALGR, OTC: ALGRF).
• Flagship Project: Adelita Project in Sonora, Mexico, 100% owned.
• Mineralization Type: Skarn system with porphyry vectors; targets include copper, gold, and silver.
• Key Discovery: Cerro Grande skarn target showing high-grade intercepts (e.g., 36m @ >1.0% Cu) and molybdenum enrichment suggesting deeper porphyry potential.
• Exploration Status: Phase I drilling completed; Phase II targeting expansion and maiden testing of new district-scale targets.
