Mexico’s Best Gold Drilling Intercepts, First Quarter 2026

/ Gambusino Prospector / Leave a comment

Companies working in Mexico released results from drilling campaigns in twenty properties during the second quarter of 2026. The highest gold intercept was, again, at Heliostar’s Ana Paula project in Guerrero, with almost 100 m averaging 10.90 gpt Au. Ana Paula is part of the Guerrero Gold Belt, presenting skarn and replacement mineralization with significant gold in sulfide rich breccias, with an uncommon late epithermal overprint. Other projects displaying skarn/replacement mineralization include Adelita (considered as distal to a porphyry copper system) in Sonora and Cosalá in Sinaloa. The only volcanogenic massive sulfides (VMS) deposit in the list, Campo Morado, in Guerrero, attained again the second place with its long multigram gold intervals. The third property in the list, Dios Padre, is characterized by strongly zoned breccias related to porphyry copper style intrusions in the Santa Rosa de Yecora district in Sonora.

Epithermal systems represent over 60 percent of the entries in the table below. Intermediate sulfidation epithermal deposits are the most numerous, although more common in the lower part of the table as these tend to display lower grades. Included in this category are Zacualpan, Copalito, Tahuehueto, Zacatecas Silver, Cruz de Plata, Alamos Silver, San Marcial and Gavilanes. Low sulfidation epithermal deposits include La Colorada? (Sonora), Copalquín, Claudia and Terronera. The question mark on La Colorada arises from some of its characteristics not being that clear (Heliostar geologists disagree on the question mark).

Santo Tomás is a porphyry copper system and San Antonio a clear example of an iron oxide copper gold (ICOG) mineralization system.

Summarizing, thirteen of the twenty properties on the list are epithermal systems, three present some type of skarn mineralization, one is a breccia related to a porphyry copper system, another one a volcanogenic massive sulfides (VMS) deposit, other one a porphyry copper system and one more an IOCG system.

El pago de utilidades pone en riesgo la titularidad de contrato en la mina La Herradura de Peñoles

Por: María del Pilar Martínez 02.07.2026

El Sindicato Nacional Minero Metalúrgico de la Confederación de Trabajadores de México (CTM), encabezado por Javier Villarreal, inició el proceso legal para demandar la titularidad del contrato colectivo de trabajo en la mina La Herradura, ubicada en Caborca, Sonora, propiedad de Grupo Peñoles.

La organización gremial busca representar a los más de 2,500 trabajadores de este yacimiento de oro, debido a la inconformidad de la plantilla laboral con los montos otorgados por concepto de la Participación de los Trabajadores en las Utilidades (PTU). De acuerdo con representantes sindicales, los mineros han percibido un límite de 90 días de salario durante los últimos cinco años a partir de la reforma en la materia, mientras que el valor de la onza de oro superó la barrera de los 4,000 dólares.

Por ello, los trabajadores de La Herradura iniciaron su afiliación a la organización adherida a la Confederación de Trabajadores de México (CTM) ante la falta de acuerdos con la actual dirigencia a cargo del Sindicato Nacional de Trabajadores Mineros “Frente”, liderado por Carlos Pavón Campos…….
