Mexico’s Best Drilling Intercepts, Fourth Week of April 2026

Three companies announced results from drilling campaigns in Mexico during the week.

Heliostar Metals reported assay results from five holes that are infilling the High Grade Panel at its Ana Paula project in Guerrero. Another fourteen holes on the same area are awaiting results, same that are to add to the information gathering for an upcoming feasibility study (FS) and the future mine plan. “Mineralization at Ana Paula occurs as disseminations or vein stockworks with variable controls including rock porosity, lithology and fault networks” interpreted to be a high level example of the gold skarn mineralization on the other large deposits present in the Guerrero Gold Belt.

Impact Silver announced results from two holes drilled in the SE Area of the San Marcial deposit at its Plomosas project in Sinaloa, confirming mineralization up to 500 m downdip from surface. Two rigs are on site and additional rigs are in transit to “complete the planned 20,000 metres by H2 2026”. Recent drilling “has delineated wide, high-grade, shallow hydrothermal breccias in the San Marcial Area, including the SE Area discovery” in this intermediate to low sulfidation epithermal mineralization.

Impact Silver released surface drill results on the northern extension of the Carlos Pacheco vein system at its Noche Buena mine in the Royal Mines of Zacualpan District in Estado de México. The district is known for its precious metals intermediate sulfidation mineralization.

Mexico’s Best Drilling Intercepts, Third Week of April 2026

Two companies announced results from drilling campaigns in Mexico during the week.

Mercado Minerals reported assay results from resampling of historic diamond drill holes at the Copalito project in Sinaloa, proving a good correspondence between the re-assay drill composite intercepts and the previous ones. The company re-sampled 12 of the 81 historic diamond drill holes. Copalito mineralization is described as having low to intermediate sulfidation affinity.

Pacifica Silver announced results from the first 16 holes of its phase II, 20,000 m diamond drilling campaign at its Caludia project in Durango. Fourteen holes were collared on the Aguilareña area and two more on the Central vein; to date 9,918 m in 38 holes have been completed. The Claudia project comprises low sulfidation epithermal mineralization in multiple veins

Mexico’s Best Drilling Intercepts, Second Week of April 2026

Two companies announced results from drilling campaigns in Mexico during the week. Included in the table below are also the intervals from drilling at Cosalá by Americas Gold Silver, same that were published the previous week and omitted in the respective compilation.

Heliostar Metals presented results from six holes on the Expansion Zone below the High Grade Panel at its Ana Paula project in Guerrero, where the company has completed 28,318 m in 84 holes during its 2025-2026 drill campaign. Ana Paula is within the Guerrero Gold Belt, which is characterized by gold bearing skarns. At the project mineralization has been described to be mainly in a sulfide rich breccia, replacement bodies and minor skarn bodies, with a late epithermal overprint. The present press release states “We interpret Ana Paula to be higher in the same geological setting as its large neighbours in the Guerrero Gold Belt… Mineralization at Ana Paula occurs as disseminations or vein stockworks with variable controls including rock porosity, lithology and fault networks”.

Mithril Silver and Gold presented results from drilling on Targets 3 and 5 at its Copalquín project in Durango. High-grade gold-silver mineralization is hosted by low sulfidation epithermal mineralization in volcanic rocks of the Sierra Madre, although in narrow veins in the present release.

Americas Gold and Silver released results from resource definition and exploration drilling at its Cosalá mine in Sinaloa. The program is focusing on upgrading resource classifications on the UZ and Zone 120 deposits and exploration of the El Alacrán discovery zone.

Mina Santa Fe en Sinaloa: Lo que se sabe del rescate de los cuatro mineros atrapados tras el derrumbe

María Fernanda Sosa Santiago

Publicado: 08.04.2026

A 13 días del derrumbe en la mina Santa Fe, en el municipio de El Rosario, Sinaloa, las labores de rescate continúan en medio de condiciones extremas. Este miércoles 8 de abril, autoridades reportaron el rescate con vida del segundo minero localizado y confirmaron el hallazgo sin vida de un tercer trabajador, mientras persiste la búsqueda del último minero que permanece atrapado.

El accidente ocurrió el pasado 25 de marzo, cuando colapsó una presa de jales al interior del yacimiento, lo que provocó la irrupción de agua y lodo en las galerías subterráneas. De los 25 trabajadores que se encontraban en la mina, 21 lograron salir, pero cuatro quedaron atrapados.

Desde entonces, el operativo se convirtió en una carrera contra el tiempo y las condiciones adversas: inundaciones, visibilidad nula y túneles convertidos en ríos subterráneos.

Más de 300 rescatistas y un operativo contra el tiempo


El rescate ha movilizado a más de 300 elementos, entre personal de las Fuerzas Armadas, buzos especializados y brigadas de Protección Civil. Las labores han requerido bombeo constante de agua,así como el reforzamiento de estructuras para avanzar en las galerías.

Cuatro días después del derrumbe, los equipos habían logrado avanzar cerca de 1.5 kilómetros dentro de la mina, aunque las condiciones complicaron el acceso a las zonas más profundas, donde se estimaba la ubicación de los trabajadores.

El trabajador logró resguardarse en un punto elevado dentro de la mina tras detectar el ingreso de lodo. Fue trasladado al Hospital General de Mazatlán, donde fue dado de alta horas después, con un cuadro de deshidratación leve.

Segundo minero localizado con vida


El segundo sobreviviente, Francisco Zapata Nájera, de 42 años, fue localizado el 7 de abril a unos 300 metros de profundidad, tras más de 300 horas de labores ininterrumpidas.

Nájera fue finalmente rescatado la mañana de este miércoles 8 de abril y recibió atención médica inmediata por parte de paramédicos en la zona de operaciones. Posteriormente, fue trasladado en un helicóptero de la Fuerza Aérea Mexicana al Hospital General de Mazatlán, donde será atendido por especialistas.
