Algo Grande Reports Phase II Drill Update and UAV Magnetic Survey Results at Adelita; Multiple Porphyry Centers Identified at Depth

Algo Grande Copper Corp. reports that its Phase II drill program at the Adelita Project is progressing ahead of schedule. Hole 001 is complete, and the rig is advancing to Hole 002 of a planned 21-hole, approximately 8,000-metre campaign. A second drill rig is mobilizing to the site, with the first batch of assay results targeted for August 2026.

The company also completed a high-resolution UAV magnetic survey covering 1,200 line-km, delivering a sevenfold improvement in spatial resolution over legacy VTEM data. 3D Magnetic Vector Inversion (MVI) has identified three interpreted porphyry-related intrusive centers at depth: Mezquital, Cerro Grande Central, and a newly identified target, La Corona. Structural analysis highlights a primary NW-SE Laramide magmatic/hydrothermal corridor, with multiple new untested structural intersection nodes across the 5,895-hectare property.

Algo Grande Copper Corp. (ALGR) is executing its Phase II exploration program, which was originally announced in May and June 2026. The company is progressing ahead of schedule and has mobilized a second rig, a move that demonstrates operational efficiency and management's commitment to the exploration roadmap.

Recent UAV magnetic surveys and MVI results have added geological confidence to the district-scale model. However, these findings do not constitute new drill intercepts or resource estimates. The information is incremental and aligns with prior guidance, without materially altering the company's near-term cash burn, valuation, or capital requirements. Consequently, the market impact is expected to be muted, serving as a confidence-building update rather than a catalyst for immediate price appreciation.

Algo Grande Copper Corp. (TSXV: ALGR) is a growth-focused copper exploration company centered on the 100%-owned Adelita Project in Sonora, Mexico. The project spans 5,895 hectares in the prolific Arizona-Sonora copper belt. Its flagship asset is the Cerro Grande Skarn, a high-grade copper-gold-silver system. The project is in the exploration stage, with exploration, social, and underground mining permits secured. The company rebranded from Kenadyr Metals in late 2025, acquiring the Adelita project and reactivating TSXV trading. Its exploration strategy leverages AI-driven data integration, high-definition geophysics, and systematic drilling to expand the skarn corridor and test deeper porphyry systems.
