Silver Tiger intersected 2.1 metres grading 7,720 g/t silver equivalent at its El Tigre Project in Sonora. The high-grade result further demonstrates the strength and continuity of mineralization within the developing underground resource area and supports the company’s ongoing exploration and resource-expansion program.

Tocvan confirmed gold-silver mineralization along the 1.3-kilometre El Mezquite trend at Gran Pilar. Hole JES-26-162 returned 247.05 metres grading 0.10 g/t gold and 2.61 g/t silver from surface, supporting lateral and vertical continuity and warranting further step-out and infill drilling.

Oroco reported ten Phase 2 drill holes from the South Zone at Santo Tomás, Sinaloa. Highlights include 369.3 m grading 0.45% CuEq, 154 m at 0.51% CuEq and 103 m at 0.58% CuEq. Mineralization below current PEA pit limits indicates expansion potential and supports resource upgrading and prefeasibility work.

Zacatecas Silver expanded the mapped Oso Negro vein system at its Esperanza project to over three kilometres. Phase-two rock-chip sampling returned grades up to 20.3 g/t gold and 3,480 g/t silver, identifying multiple high-grade zones and supporting further exploration and drill-target development.

Questcorp reported Phase 2A drilling results from La Union in Sonora, confirming a near-surface mineralized structure at Union Norte. Highlights include 14.6 m grading 0.45 g/t AuEq and 9.1 m at 0.76 g/t AuEq. Geophysics also defined a one-kilometre chargeability anomaly at Luis Hill ahead of Phase 2B drilling.

Riverside Resources’ Phase 2A drilling at the Union Project in Sonora intersected near-surface gold and base-metal mineralization. Union Norte returned 14.60 metres grading 0.45 g/t AuEq and 9.10 metres grading 0.76 g/t AuEq, including 1.50 metres at 3.38 g/t AuEq. Phase 2B drilling will test Union Norte, Union, Luis Hill and Jabalí.

Pinnacle Silver and Gold’s underground drilling at El Potrero in Durango returned 10.89 metres grading 6.19 g/t gold and 90 g/t silver, including 0.41 metres at 58.2 g/t gold and 631 g/t silver. Results confirm and extend high-grade mineralization at the historic Pinos Cuates mine, supporting future resource estimation and mine planning.

First Majestic reported high-grade drill results from San Dimas, including 1.30 metres grading 6,994 g/t silver equivalent at the Luz vein and 0.88 metres grading 5,835 g/t silver equivalent at Sinaloa-Elia. Drilling supports resource conversion and expansion, while new discoveries at Convención and El Cristo broaden the exploration footprint.

Defiance Silver reported high-grade results from San Acacio in Zacatecas, including 0.31 metres grading 990 g/t silver within 1.40 metres at 221 g/t silver, and 0.34 metres at 735 g/t silver. The 6,132-metre program supports an upcoming mineral resource estimate, while assays remain pending from Lucita South drilling.

EV Resources commenced crushing antimony ore at its Tecomatlán processing plant in Puebla, launching a proof-of-concept campaign targeting production of the facility’s first antimony concentrate. Approximately 200 tonnes of ore will be processed through crushing, grinding and flotation to demonstrate plant performance and establish operating parameters.
