/ 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.

ON MEXICO ISSUES

  • PDAC 2025 Insights on Mexico. With significant government attendance and a more favorable message there is a cautiously optimistic mood in the Mexican mining industry. Faster permitting times are expected, along with the emission on the first half of the year of the rulebook that is to guide the application of the 2023 mining law. An exploration system in partnership with the government is probably not going to work.

ON EXPLORATION

  • Kingsmen Resources Ltd. reported additional results from the exploration program at its Las Coloradas project in Chihuahua. The company published geochemical maps for different elements of surface rock samples on the La Silvia and La Plata zones, north of the La Soledad structure. The geochemical signatures “are interpreted to indicate different pulses of mineralization and possibly indications of different styles of mineralization along and at depth in the two structures.

ON MINING

  • Elemental Altius Royalties Corp. informed on record preliminary revenue in 2024 from its portfolio of royalties, without figures per property. During 2024 the company had revenue of US$21.6 M, based on the sales of approximately 8,990 Oz AuEq (holds royalties on Mercedes, Sonora).
