Mercado Minerals reported additional drill results from its inaugural 3,000-metre diamond drilling program at the Copalito Project in Sinaloa. Highlights included 3.5 m grading 686 g/t silver equivalent, including 1.2 m at 1,120 g/t AgEq, at the El Agua vein. Drilling also expanded the 5 Señores vein, extending mineralization along strike and at depth, with both targets remaining open for further expansion.

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.

Regency Silver reported strong step-out drill results from its wholly owned Dios Padre Project in Sonora. Hole REG-26-35 intersected 36.35 metres grading 5.06 g/t gold, 41.85 g/t silver, and 1.10% copper, confirming high-grade mineralization at depth. The program indicates a large, vertically zoned Au-Cu-Ag system extending approximately 775 metres down plunge, with silver-rich zones near surface transitioning to gold-copper mineralization at depth.

Silverco Mining reported initial underground drill results from its 30,000-metre 2026 program at the Cusi Mine in Chihuahua, highlighting 1,712 g/t AgEq over 1.4 metres in hole UGCU-26-02 within the Promontorio zone. Results are adjacent to planned first-year mining stopes and support resource expansion, mine-plan optimization, and the planned H2 2026 restart. Other notable intercepts included 303 g/t AgEq over 8.3 metres and 428 g/t AgEq over 1.1 metres.

IMPACT Silver reported high-grade drill results from the north extension of the Carlos Pacheco Vein at its producing Noche Buena Mine in Mexico, including 1,333 g/t silver over 5.72 metres within a broader interval of 6.55 metres grading 1,333 g/t silver. The results extend known mineralization northward and support further resource growth potential at the operation.
