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.

Coeur Mining reported strong 2025 exploration results. At Las Chispas (Mexico), high-grade intercepts include 0.3m at 158 g/t Au & 13,430 g/t Ag in North Las Chispas vein; Augusta vein expanded. Drilling ramped to nine rigs for resource growth. At Kensington (Alaska), intercepts like 2.2m at 395.9 g/t Au in Upper Zone; Elmira expansions and new EHM discovery extend five-year mine life.

Tocvan Ventures Corp. announced a September 10, 2025 webinar at 10 a.m. MDT, where CEO Brodie Sutherland will detail the Gran Pilar Gold-Silver Project’s roadmap from exploration to production, including pilot plant progress and drilling results. Recent warrant exercises raised funds to accelerate programs, with more expected. Highlights include 83.5m @ 1.3 g/t Au intercepts and 62% bulk sample gold recovery.

Capitan Silver Corp. announced high-grade assay results from its 2025 drill program at the Cruz de Plata project in Durango, Mexico. Hole 25-ERRC-12 yielded 2,636 g/t Ag over 1.5 m, extending the Jesús María zone 150 m east. A new high-grade zone was discovered north of Jesús María, with ongoing drilling to explore further potential.

Mithril Silver and Gold Limited is advancing exploration at its Copalquin property in Mexico, fully funded for 45,000m of drilling over 12–14 months. Drilling at Apomal (Target 5) and high-grade intercepts at La Soledad and Zaragoza (Target 1) confirm significant gold-silver potential. A third drill rig and aeromagnetic survey are planned for 2026 and Q4 2025, respectively.
