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

/ Gambusino Prospector / Leave a comment

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

Luca Mining reported assay results from drilling designed to expand mineral resources at its Tahuehueto mine in Durango. The company has identified more than 11 km of prospective vein structures, completing 67 underground holes for 11,450 m and 38 surface holes for 7,236 m using “HQ”, “NQ” and/or “BQ” sized diamond drill core at Creston, Perdido, El Rey, Catorce and Santiago targets. The property hosts intermediate sulfidation epithermal mineralization.

Pacifica Silver announced assay results for 27 holes from its ongoing phase II drilling campaign at its Claudia project in Durango. The results extend mineralization on the Central vein to 750 m on strike and 100 m down dip and defined more than 3.9 km of mineralized strike length across the Aguilareña, Central and Justina veins. Mineralization at the property is overwhelmingly of low sulfidation epithermal character.

Algo Grande Copper reported assay results from a new hole at its Adelita property in Sonora. More than 4,000 m have been drilled to date on this 7,200 m phase II drilling program. The hole intercepted several shallow skarn horizons and a new structurally controlled skarn at depth, that received the name of Margarita skarn. The mineralization at the project is interpreted by the company as the distal effect of a porphyry copper system at depth.

Avino Silver & Gold Mines reported results from thirteen holes completed on its first phase of infill and extension drilling at La Preciosa, in Durango. The company view is that structures are wider and the grade higher than in the current mineral reserves and resources, while advancing toward a larger scale operation. Mineralization at the project is of intermediate sulfidation characteristics: “Quartz veins are accompanied by adularia, barite, calcite, and rhodochrosite of variable timing, as well as acanthite, freibergite, Ag sulfosalts and minor electrum, plus variable amounts of pyrite, honey-coloured sphalerite, tennantite/tetrahedrite, chalcopyrite and galena”.

Mithril silver and Gold disclosed drilling results from Target 4 at its Copalquín property in Durango. This work extends mineralization along the Copalquín-Zaragoza structure to 700 m of strike length, raising the potential for resource growth. In general, the property presents low sulfidation epithermal mineralization, but the results from Target 4 on this release seem more akin to intermediate sulfidation epithermal mineralization.

Kingsmen Resources announced results from three drill holes at Las Coloradas project in Chihuahua. The reported assays are from La Leona zone at the Soledad II structure, which displays intermediate sulfidation epithermal characteristics.

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.

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

/ Gambusino Prospector / Leave a comment

One company released results from drilling on a project in Mexico during the week.

Silverco Mining reported intercepts from fifteen holes from its ongoing 30,000 m drill program at the past producing Cusi property in Chihuahua. The program will support the restart of mining in Q4 2026 and an updated mineral resource estimate planned for H1 2027. “Mineralization at Cusi occurs in veins with mineralogical characteristics and alteration assemblages typical of low to intermediate sulfidation epithermal deposits. Silver, gold, lead, and zinc mineralization occurs along faults and open fractures containing quartz, sphalerite, and galena, with wall rock alteration characterized by silicification, clay development, and iron oxides”.

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.
