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.

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

/ Gambusino Prospector / Leave a comment

Eleven companies released results from drilling projects in Mexico during the week, by far the highest number since this weekly compilation started back in April of 2022. For ease of reading the table has been divided into precious metals base metals sections

Zacatecas Silver reported gold, silver, lead and zinc drilling results from drilling at El Cristo vein system at its Zacatecas Silver project in Zacatecas. “Mineralization at El Cristo is of an intermediate sulphidation epithermal type, which crops out with a dilational zone that is at least 3 km along strike and up to 600 m wide… El Cristo represents the northwest strike extension of the Veta Grande vein, which has reported, but unverified, historical production of 200 Moz AgEq”.

GR Silver Mining announced gold, silver, lead and zinc results from drill holes in the SE Area Extension on the San Marcial deposit, at its Plomosas project in Sinaloa. The holes “confirm the extension of high-grade silver mineralization within chlorite–hematite hydrothermal breccias hosted at the contact between the upper Oligocene volcanic sequence and the lower Jurassic volcanosedimentary unit”. Mineralization at San Marcial is of intermediate sulfidation epithermal characteristics.

Luca Mining reported new gold, silver, copper lead and zinc assay results from the ongoing 2026 drilling exploration program at its Tahuehueto mine in Durango. Reporting “… high-grade mineralization intersected across the Creston, Perdido veins and specifically at the Catorce Zone”. Mineralization at the property presents characteristics of intermediate sulfidation epithermal systems.

First Majestic Silver announced gold and silver drill results from its ongoing 2026 exploration program at its San Dimas (also known as Tayoltita) mine in Durango. The 117,000 m drilling program supports near-mine resource conversion and growth opportunities. Vein systems tested include Sinaloa-Elia, Coronado-Carmen Escobosa, Jessica, Luz and Patricia. San Dima presents mineralization ascribed to the low sulfidation epithermal category.

Questcorp Mining reported gold, silver, lead and zinc results from Phase 2A summer 2026 drilling campaign at the La Unión project in Sonora. “Drilling intersected near-surface gold and polymetallic mineralization at Union Norte, confirmed the continuation of the historic Sproul manto/replacement system at Union Mine…”.

Defiance Silver provided gold, silver, lead and zinc results on the drilling campaign on the San Acacio resource drilling program on its Zacatecas project, in Zacatecas. The drilling campaign designed to confirm the extension on strike and at depth of the known structures has completed 6,132 m in 21 holes. “The company is looking forward to integrating the assay results from the San Acacio drilling into the Mineral Resource Estimate, which is currently underway.”

Pinnacle Silver and Gold announced ongoing underground gold and silver drilling results on the historic Pinos Cuates mine at its Potrero property in Durango. Mineralization “… occurs in a low sulphidation epithermal breccia vein system hosted within andesites of the Lower Volcanic Series..”. Upcoming surface drilling will test gaps between known mineralization and the El Capulín and La Estrella veins.

Oroco Resource reported copper, molybdenum (not included here), gold and silver assay results from its Phase 2 resource drilling program in the South Zone of the Santo Tomás project in northern Sinaloa. Two of the holes in this program ended in mineralization 90 and 200 m respectively below the current PEA limits. Santo Tomás presents porphyry copper style mineralization.

Silver Tiger Metals announced gold and silver exploration drilling results for the 2026 Summer Program on the Northern Area at its El Tigre project in Sonora. The results are from the Caleigh, Protectora and the newly discovered Northern Sotckwork Zone. “The Northern Veins consist of several historically mined veins including the Protectora, Fundadora, and Aguila … and many newly discovered veins including Benjamin, the Benjamin Shale and Caleigh”. Mineralization at El Tigre presents characteristics mainly akin to intermediate sulfidation epithermal systems.

Algo Grande Copper reported Copper, gold, silver and zinc results from its Phase II drilling program on the Cerro Grande skarn, at its Adelita project in Sonora. “The mineralization in the skarn horizon occurs within massive brown garnet-dominant skarn (garnet > pyroxene), which the Company interprets as a high-temperature prograde skarn subsequently overprinted by a Cu-rich mineralizing event. The association of garnet-dominant skarn with bornite, chalcopyrite and abundant chalcocite suggests the drill hole may be approaching the proximal part of the mineralizing system, or a major hydrothermal fluid conduit”. Skarn mineralization at Adelita is interpreted as proximal to a porphyry copper system.

Tocvan Ventures announced new gold and silver drill results from El M;ezquite trend at tis Gran Pilar project in Sonora. “The latest drilling confirms gold mineralization along the 1,300-metre El Mezquite trend… located approximately 1.6 to 1.9 kilometres east of the Main Zone”. Mineralization at Gran Pilar presents intermediate sulfidation epithermal characteristics, being probably distal to a porphyry copper system.
