ON MEXICO ISSUES

• Colibri Resource Corporation, reported the best drilling intercepts in Mexico on the second week of March, 2026. Details are shown in the table below:

ON EXPLORATION

• Algo Grande Copper Corp., provided an exploration update on its Adelita project in Sonora. The company recently completed Phase 1 drilling with assay results pending. Surface prospecting across the property collected 49 rock samples, 19 of which graded above 1% copper, confirming copper–gold–silver mineralization across multiple targets including Potrero South, Las Trancas, Cerro Grande Northwest, La Molina, and Mezquital. A significant new skarn zone was discovered at Potrero south, about 3 km south of Cerro Grande, with over 300 meters of surface exposure and samples exceeding 3% copper. Other highlights include high-grade samples including one with 41.4 % Cu, 1.97 g/t Au 1,570 g/t Ag at Las Trancas and 1.99 % Cu, 17.9 g/t Au and 44 g/t Ag at La Molina targets. The company confirmed mineralization on both limbs of the Cerro Grande limestone fold, and encouraging copper-bearing float samples associated with tourmaline breccias at Mezquital indicating possible porphyry systems. The results suggest a district-scale, multi-deposit copper-dominant skarn-porphyry system with notable gold and silver credits. Follow-up exploration including Phase II drilling is planned for Q2 2026 to target these multiple prospects.
• Colibri Resource Corporation released assay results from its Phase 1 reconnaissance RC program completed at its El Plomo project in Sonora. The company informed that 18 out of 22 holes intersected gold. Drilling highlights include hole PL26-017 with 2.92 g/t Au over 7.5m, including 9.95 g/t Au over 1.5m; hole PL26-015 with 0-73 g/t Au over 30m including 1.01 g/t Au over 6m; hole PL25-011 with 0.45 g/t Au over 30m, including 1.16 g/t Au over 6m; including 2.12 g/t Au over 1.5M; hole PL25-004 with 1.29 g/t Au over 4.5mm; and hole PL25-005 with 0.28 g/t Au over 12m.
• Capitan Silver Corp., informed that a third rig has arrived at its Cruz de Plata project in Durango. This rig is the second of three core drill rigs that will join the existing RC drill rig to complete the ongoing aggressive 60,000 drilling campaign for 2026, which is focused on expanding the high grade silver zones identified at the property, as well as to drill-tst mineralization along the Jesus Maria silver trend. To date, 34 drill holes are pending of assay results, including the first seven core holes drilled with the first diamond rig which commenced drilling last February, 2026.
• Defiance Silver Corp., announced that it received the approval for its Informe Preventivo (IP) from SEMARNAT to conduct drilling at its San Acacio project in Zacatecas.
