Oroco reported additional Phase 2 drill results from the South Zone at its Santo Tomás copper project, with drilling confirming and locally improving upon the 2024 resource model. Highlights included 90 m grading 0.53% CuEq, 48.6 m grading 0.67% CuEq, and several near-surface mineralized intervals that may reduce stripping requirements. The program is aimed at increasing resource confidence ahead of an updated resource estimate and Pre-Feasibility Study.

Goldgroup has commenced a fully funded 24,000-metre diamond drilling program at its 100%-owned San Francisco Gold Project in Sonora. The US$8 million program aims to update the resource model, optimize mine planning, collect structural data, and support the restart of gold production targeted for late 2026 or early 2027. Drilling is expected to be completed in Q3 2026.

Southern Silver has begun an infill drilling program at the Puro Corazón target within its Cerro Las Minitas project in Durango. The program aims to expand and upgrade resources, integrate the recently acquired Puro Corazón claim into the larger project, and support an updated mineral resource estimate and PEA. The work is expected to enhance project economics, mine planning, and development potential.

Silver Storm received SEMARNAT permits for 62 drill pads and 27 access roads at its La Parrilla Silver Mine Complex in Durango, valid for four years. The permits support surface drilling at the La Ilusión-Argenis, 14 Marcos, and Rosarios–C340 targets. SEMARNAT also extended the tailings storage facility permit for 10 years, supporting ongoing operations and resource expansion efforts.

Endeavour Silver reported high-grade silver-gold drill results from its first exploration program at the Terronera mine since 2020. Drilling at the Terronera and La Luz vein systems extended mineralization along strike and at depth, highlighting potential for future resource growth, mine-life extension, and expansion beyond the current mine plan.

Heliostar reported strong drill results at the Veta Madre zone of its La Colorada mine, extending high-grade gold mineralization beyond the current reserve pit. The company has received all key permits for the pit expansion, plans to begin waste stripping in Q3 2026, and is evaluating a larger pit that could add approximately 20,000 ounces of gold production.
