Mexico’s Best Silver Drilling Intercepts, Third Quarter 2026

/ Gambusino Prospector / Leave a comment

Thirty companies released silver results from drilling programs in Mexico during the third quarter of 2026. Coeur Mining produced the highest silver intercept at its Palmarejo property in Chihuahua, with 11.48 m grading 1,250 gpt Ag, including 5.31 m of 2,154 gpt Ag. The results are from resource drilling on the Main Mine Trend and exploration on the Eastern District. “Recent results support the potential of the Eastern District to become a significant new mining front at Palmarejo, both in the medium-term near the Main Mine Trend (Independencia Sur), and longer-term at San Miguel and La Unión…” Mineralization at Palmarejo presents characteristics of low sulfidation epithermal systems.

Three quarters of the projects in this table correspond either to intermediate or low sulfidation epithermal mineralization systems. The more numerous are those of intermediate sulfidation affinity, including Cusi, El Tigre, Gavilanes, Columba, Alamos Silver, Cruz de Plata, Don David, San Marcial, San Acacio, Copalito, Gran Pilar (distal to a porphyry copper system), Las Coloradas, Zacatecas Silver and Tahuehueto. Low sulfidation epithermal systems in the list comprise, besides Palmarejo, Las Chispas, Copalquín, San Dimas, Claudia, Potrero, La Virginia and Cerro Caliche. 

The Morelos Complex, Cerro Las Minitas, La Parrilla, Cosalá and Cerro Las Minitas present skarn and/or carbonate replacement (CRD) mineralization styles, while La Parrill adds intermediate sulfidation epithermal mineralization to that mix and Adelita is a skarn distal to porphyry copper style intrusions. Campo Morado is the only volcanogenic massive sulfides (VMS) property in the table and Santo Tomás is the sole porphyry copper deposit.

Most of the drilling activity in the quarter was in the north and northwest of the country. By State, Durango has nine entries in the table, Sonora eight, Chihuahua and Sinaloa four each. Guerrero and Zacatecas two each and Oaxaca one.

Mexico’s Best Drilling Intercepts, Third Quarter 2026

Companies working in Mexico released results from drilling campaigns in twenty properties during the third quarter of 2026. The higher gold intercepts were from deposits within Torex Gold’s Morelos complex in Guerrero, with the highest returning over 36 m grading almost 12 gpt Au. These deposits are part of the Guerrero Gold Belt, presenting Au-Cu-Ag skarn and replacement mineralization. But skarns are not commonly the best example of gold deposits in Mexico, with the obvious exception of these in the Guerrero Gold Belt. The only two other skarns in this table are way down: Adelita, probably linked to a porphyry copper system, and La Parrilla, a complex deposit displaying also carbonate replacement (CRD) and intermediate sulfidation epithermal mineralization styles. The second top results come from Luca Mining’s Campo Morado, also in Guerrero, which is also the only volcanogenic massive sulfides (VMS) deposit on the list.

Epithermal systems represent 70 percent of the entries in the table below. The highest ranking is third on the list, Coeur Mining’s Palmarejo mine in Chihuahua, same that presents low sulfidation epithermal characteristics. Other low sulfidation epithermal deposits comprise Potrero, San Dimas, Cerro Caliche, Las Chispas, Copalquín and La Virgina. But Intermediate sulfidation epithermal deposits are the most numerous with 13 assigned to that category, including: Gran Pilar (likely associated to a porphyry system), El Tigre, Tahuehueto, Gavilanes, Don David, Cusi, Copalito, Cruz de Plata, San Acacio, Alamos Silver, San Marcial, Las Coloradas and Columba.

Deposits that display carbonate replacement mineralization (CRD) include Cosalá (which also have intermediate sulfidation epithermal mineralization), and La Unión, in Sonora, as well as the previously mentioned La Parrilla.

Santo Tomás is a porphyry copper system and San Antonio and San Javier are part of an iron oxide copper gold (ICOG) mineralization system in the same district.

Summarizing, twenty one of the thirty properties on the list are epithermal systems, three present some type of skarn mineralization, two more have characteristics of carbonate replacement deposits (CRD) another one has characteristics of a volcanogenic massive sulfides (VMS) deposit, one more is clearly a porphyry copper system and two more are part of an IOCG system. The gold intercepts are clustered in the north and northwest part of the country, with 26 reported in Sonora, Durango, Chihuahua and Sinaloa.
