Zacatecas Silver has increased the Esperanza Gold Project’s Measured & Indicated resource by 21% to 1.15 million AuEq ounces. The updated resource totals 45.4 Mt grading 0.79 g/t AuEq and remains amenable to conventional open-pit heap-leach mining. The highest grades occur near surface, supporting favorable project economics and development potential.

Capitan Silver has received a key permit allowing it to drill beyond the currently defined Jesús María silver trend at its Cruz de Plata project in Durango. The permit opens several previously untested regional targets on newly acquired ground, supporting the company’s view that Cruz de Plata may represent a much larger district-scale silver system than previously recognized.

EV Resources has established a maiden exploration target of 1.8–5.0 Mt grading sufficient to contain 70,000–166,000 tonnes of antimony at its Los Lirios Project in Oaxaca. Early drilling confirmed a shallow, laterally extensive carbonate replacement system, and Phase 2 drilling will target higher-grade feeder structures with the goal of delivering a maiden JORC resource later in 2026.

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.
