Algo Grande Copper Intersects 30.23 Metres Grading 1.5% CuEq, including 3.55 Metres at 9.4% CuEq and 1.2-Metre Interval at 15.8% CuEq, 100 Metres Vertical Step-Out from Historical Intersects

Algo Grande Copper Corp. (ALGR) has released the first assay results from Phase II hole AG-CG-PH2-002 at the Cerro Grande skarn discovery within its Adelita Project in Sonora, Mexico. The hole was completed at a depth of 661.80 meters.

The headline intercept from the drill hole is 30.23 meters at 1.5% copper equivalent (CuEq) starting from 146.70 meters, containing 0.83% copper, 47.3 grams per tonne silver, and 0.40 grams per tonne gold. This interval includes a higher-grade segment of 3.55 meters at 9.4% CuEq, with 5.26% copper, 311.8 grams per tonne silver, and 2.22 grams per tonne gold. Within that, a 1.20-meter interval returned 15.8% CuEq, containing 9.84% copper, 638 grams per tonne silver, and 0.95 grams per tonne gold. Locally anomalous zinc concentrations of up to 1.88% were identified within the 1.20-meter high-grade interval, though zinc is not included in the CuEq calculation.

Assays are currently pending for the section below 179 meters, where 40.40 meters of visually mineralized core was logged between depths of 179 and 301 meters. Three additional holes, AG-CG-PH2-003, 004, and 005, have undergone visual logging only, with assay results still pending.

Separately, the company announced a marketing consulting agreement with Plutus Invest & Consulting GmbH valued at up to EUR 250,000.

Algo Grande Copper Corp. (ALGR) is a pre-resource exploration company with no mineral resource or reserve defined at its Adelita project. The most material question facing the company is whether the Cerro Grande deposit can grow into a large, continuous skarn system. Recent data confirms high-grade Cu-Ag-Au skarn mineralization located 100 meters shallower than Phase I, improving on the previous best core-length intercept in CuEq-metres. This result represents a step-out that adds a new shallow position to the system, rather than serving merely as infill.

The stock rallied from approximately C$0.57 in early September to C$0.73 on September 9, moving into this first Phase II assay release. While this represents a meaningful pre-release move, the share price remains well below its C$0.95 high, and the market capitalization stands at only about C$35 million. The press release result exceeds the prior Phase I anchor in contained grade-thickness, indicating the release should not be treated as a miss against the embedded anchor.

Given the stage of the company, the findings are market-relevant and positive, though not yet transformational. True width, continuity, and metallurgy remain unresolved, and assays have been received for only one Phase II hole.

Algo Grande Copper Corp., formerly Kenadyr Metals Corp., is a Canadian-listed mineral explorer focused on its 100%-owned Adelita Project in Sonora, Mexico. The project sits within the Arizona-Sonora copper belt and covers approximately 5,895 hectares. The primary target is the Cerro Grande copper-silver-gold skarn, which features a district-scale 6 km mineralized corridor and includes multiple outer targets such as Cerro Potrero South and Las Trancas. The geological model describes a skarn-porphyry system, with geophysical and geochemical evidence suggesting potential porphyry intrusions at depth. No mineral resource or reserve has been estimated to date.

Phase I drilling consisted of four holes totaling about 2,000 meters. Phase II drilling, conducted with Major Drilling Group International, comprises approximately 8,000 meters.

In financial context, Algo Grande reported a Q1 2026 net loss of about C$2.39 million. As of that period, the company held approximately C$5.54 million in cash and C$5.25 million in working capital, with 42,339,746 shares outstanding. On September 1, 2026, a placement closed for about C$4.79 million at C$0.60 per share, adding approximately 7.98 million shares. This brings the approximate current basic share count to 50.3 million, resulting in an approximate market capitalization of C$35 million at a price of C$0.70.
