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.  

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

Only one company released results from drilling projects in Mexico during the week.

Oroco Resource reported assay results from ten holes of its Phase 2 resource drilling program in the South Zone of its Santo Tomás project in Sinaloa. The Santo Tomás deposit is a porphyry copper system centered in the igneous rocks that intrude a sedimentary package and its overlying volcanic rocks. The mineralizing system has a geochemical signature with strong copper, molybdenum, gold and silver grades. Some subsidiary mineralization in carbonates sourced the base metals intercepts included below.

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

/ Gambusino Prospector / Leave a comment

Four companies released results from drilling projects in Mexico during the week.

Axo Metals announced results from 29 holes representing approximately 5,000 m of drilling. These are the first resource growth and step out drilling done in the property since its acquisition by the company. The project is within the San Javier mining district in Sonora, displaying clear iron oxide copper gold (IOCG) mineralization.

Capitan Silver reported results from 35 drill holes from its 60,000 m diamond and reverse circulation drill programs at its Cruz de Plata project in Durango. The results are from the three major target areas of the Jesús María Silver Trend, expanding known mineralization to 2.8 km. “The remainder of the 60,000 m program for this area is focused on drilling the strike length of the Jesus Maria Silver Trend to a depth of 500 m vertically from surface with down-dip step outs increasing to 80 to 175 m with diamond drilling. The RC rig is now fully dedicated to drilling newly-permitted targets”. The Jesús María zone presents intermediate sulfidation epithermal mineralization, while the gold resource at Capitan Hill is in a low sulfidation epithermal system.

Kootenay Silver reported assay results from  expansion drilling along the D vein at its Columba project in Chihuahua. “The current exploration work comprises a phased 60,000-metre drill program focused on expanding the resource detailed in the Company’s recent NI 43-101 Mineral Resource Estimate”. Columba contains mineralization with intermediate sulfidation epithermal characteristics.

Americas Gold and Silver announced drill results from the ongoing resource conversion drilling program at the Coslá Complex in Sinaloa. “The assays released are a result of infill and step-out drilling conducted in 1H 2026 at the San Rafael Upper, 120 Upper and 120 Lower deposit”. Mineralization at the property includes exoskarn, endoskarn, carbonate replacement (CRD), mantos and chimneys.
