The five-year Informe Preventivo issued by the Secretaría de Medio Ambiente y Recursos Naturales Mexico will allow for the drilling of step-out and exploration holes at 46 new drill sites in the San Marcial Area.

Pacifica Silver Corp. (CSE: PSIL) announced a Fall 2025 exploration program at its Claudia Silver-Gold Project in Durango, Mexico. The program includes an 8,000-metre Phase I drill campaign starting late September, targeting high-grade silver-gold veins, alongside surface sampling, geological mapping, and a 27-line km geophysical survey to enhance understanding and identify new drill targets.

Chesapeake Gold Corp. updates on its sulphide leach technology and Lucy exploration. Metates PFS metallurgical testwork advances positively, with third-party testing on three projects underway and new patents filed. At Lucy, a new 200m gold corridor (up to 1.33 g/t Au over 15m) and copper anomalies (up to 2% Cu) identified; project may extend 3km. Drilling planned post-current surveys.

GoGold Resources Inc. (TSX: GGD) announces initial 2025 near-mine exploration results at Los Ricos South Project, Mexico. Highlights: LRSGT-23-001 (41,110 g/t AgEq over 1.42m, incl. 28,094 g/t Ag & 173.6 g/t Au); LRGG-24-318 (904 g/t AgEq over 0.75m); LRGG-25-324 (1,034 g/t AgEq over 1.39m); LRGG-25-337 (849 g/t AgEq over 1.50m). Drilling extends Abra Zone down-dip and south, targeting 3.5km strike.

Kootenay Silver Inc. has launched a 50,000-meter drilling program at its Columba Silver Project in Chihuahua, Mexico, with two rigs targeting D and I-Vein extensions. Five drillholes (2,500m) are complete, with results pending. The program aims to expand the maiden 54.1 Moz silver Inferred Resource (284 g/t Ag). Fully funded, it seeks to update the MRE and explore a PEA.

Luca Mining Corp. reported high-grade results from its 2025 drilling at Tahuehueto Gold-Silver Mine, Durango, Mexico. Surface drilling at Santiago Deposit yielded 14.0m at 6.68 g/t Au and 6.0m at 9.0 g/t Au, with high-grade intercepts up to 23.1 g/t AuEq. Underground drilling confirmed Creston and Perdido vein continuity, with new breccia zones indicating resource expansion potential.

Sierra Madre Gold and Silver Ltd. (TSXV: SM) plans a two-stage expansion at its La Guitarra silver-gold mine in Mexico, boosting capacity from 500 tpd to 750-800 tpd by Q2 2026 (via paste fill plant, fourth ball mill, second cone crusher) and 1,200-1,500 tpd by Q3 2027 (new dry stack TSF, second crushing circuit). Fully funded from treasury and cash flow; no new permits needed.

Pan American Silver Corp. (NYSE/TSX: PAAS) reports high-grade drill results from La Colorada mine in Mexico, extending Mariana and NC2 veins eastward over 1,000m and 2,000m strikes, respectively, with intercepts like 3.66m @ 3,844 g/t Ag, 2.30 g/t Au, 4.53% Pb, 11.05% Zn. New replacement mineralization discovered in San Geronimo/Cristina zones; 65,000m drilled Nov 2024-Jun 2025 signals resource expansion and mine life extension.

First Majestic Silver reported strong 2024/2025 drill results at the Los Gatos Mine in Chihuahua, Mexico. Drilling at the South-East, Central, and North-West Deeps zones intersected high-grade silver, zinc, lead, copper, and gold, expanding mineralization beyond current resources. The results highlight significant exploration upside and support expectations for meaningful resource growth at Los Gatos.

GR Silver Mining Ltd. announced a 75m wide silver intercept (293 g/t AgEq) in drill hole SMS25-09 at the San Marcial Area, Plomosas Project, Mexico, including high-grade intervals up to 1,915 g/t AgEq. This step-out drilling extends high-grade mineralization 100m beyond the resource outline and 450m vertically, confirming an open epithermal silver system with potential for expansion.
