Mexico’s Best Lead and Zinc Drilling Intercepts, Third Quarter 2026

/ Gambusino Prospector / Leave a comment

Nineteen companies released lead and/or zinc results from drilling programs in Mexico during the third quarter of 2026. Sothern Silver Exploration’s Cerro Las Minitas advanced project in Durango produced the best lead results from carbonate replacement mineralization, with 35 m grading 4.9% Pb, whereas Luca Mining´s Campo Morado volcanogenic massive sulfides mine sourced the best zinc intercept with 183.7 m grading 1.7% Zn. In 2025 Mexico produced 412,000 tonnes of zinc and 172,000 tonnes of lead, a two to one ratio that can be gleaned from the percentage-meter numbers from the table below.

Twelve of the nineteen properties present intermediate sulfidation epithermal mineralization, including Don David, Las Coloradas, Tahuehueto, Copalito, San Marcial, San Acacio, Gavilanes, Cruz de Plata, Columba, Alamos Silver, Cusi and Zacatecas Silver. Copalquín presents mainly low sulfidation epithermal mineralization, but the zinc rich intercept is of a more restricted intermediate sulfidation mineralization. Cosalá, La Parrilla and La Unión present mainly carbonate replacement mineralization (CRD style). Finally, Adelita is a skarn distal to a porphyry copper system.

Derrame minero en Zacatecas: Profepa cierra temporalmente parte de depósito de Peñoles

Por EFE octubre 20, 2026


La Procuraduría Federal de Protección al Ambiente (Profepa) México ordenó este martes 20 de octubre el cierre temporal de parte del depósito de jales (residuos mineros) de una mina de Industrias Peñoles en Zacatecas, después de que un derrame se extendiera por 13.58 kilómetros de un arroyo y llegara al río Súchil.

La Procuraduría Federal de Protección al Ambiente, encargada de vigilar el cumplimiento de las leyes ambientales, detalló en un comunicado que el derrame se produjo en la mina subterránea de Minera Sabinas, en el municipio de Sombrerete, que extrae plata, plomo, zinc y cobre.

Los jales son apilamientos de rocas molidas que quedan después de que los minerales como el plomo, zinc, cobre, plata y otros han sido extraídos de las rocas que los contienen.

¿Qué daños provocó el derrame en el río Súchil?
Según la Profepa, que actuó tras el aviso de un comité de vigilancia ambiental, en una inspección realizada el 8 de octubre constató “la presencia de jales en distintos puntos desde las instalaciones de la mina hasta la comunidad de Estación de Canutillo, debido a las lluvias registradas en la zona”.
