Algo Grande Copper Corp. has expanded its Phase II drill program at the Adelita Project in Sonora, Mexico, reporting an enlarged copper footprint in Hole AG_CG_PH2_002 and an extensive new intercept in Hole AG_CG_PH2_003 at the Cerro Grande skarn target.

Hole AG_CG_PH2_002 has more than doubled its visually observed copper-bearing footprint to 68.77 metres across a 154.40-metre span from 146.70 to 301.10 metres. The interval is hosted in massive brown garnet-dominant skarn, andesitic porphyry intrusion, and retrograde exoskarn containing chalcocite, chalcopyrite, bornite, covellite, chrysocolla, and intermittent molybdenite. The hole has reached a depth of 424.22 metres toward a planned 700-metre total depth.

Initial core samples down to 179 metres from Hole 2 were delivered to the ALS laboratory in Hermosillo on August 7, 2026, with assay results expected in the coming weeks.

Meanwhile, a second rig advanced Hole AG_CG_PH2_003 to 239.65 metres, intersecting copper mineralization across a combined 73.91-metre interval containing 37.42 metres of visually observed copper-bearing core. The intercept includes an upper zone hosted in garnet-dominant skarn and an extensively mineralized lower zone hosted in retrograde exoskarn. Algo Grande interprets the Hole 3 intercept as a 105-metre vertical step-out above an intercept from the inaugural Phase I campaign, indicating vertical continuity within the mineralizing system. Hole 3 remains open at depth.

"Hole 2's expanding copper zone and Hole 3's extensive new interval are building a compelling case for scale at Cerro Grande - though we are still early in testing this system. We expect assays from this drill program to start coming out in the next few weeks, kicking off a steady flow of results from ALS as we move forward."

Algo Grande holds a 100% interest in the 5,895-hectare Adelita Project within the Arizona-Sonora copper belt. All reported drill intervals are based on visual core logging, and true widths have not yet been determined.
