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.

Heliostar Metals Ltd. announced initial results from its 15,000-meter drill program at the Ana Paula project in Guerrero, Mexico, targeting resource conversion and supporting a Feasibility Study. Key intercepts include 30.2m at 6.29g/t gold, 14.75m at 13.6g/t gold, and 12.2m at 8.72g/t gold, confirming consistent high-grade mineralization. Two rigs are active, with monthly results expected through 2026.

Kingsmen updated drilling progress at its 100 %-owned Las Coloradas silver project in the Parral mining district, Chihuahua. The company completed 3,227 m of core drilling in 12 holes, testing the Soledad and Soledad II structures and geophysical targets. Drilling confirmed mineralization along strike and below the water table, validating the geological model and leaving significant targets still to test.

Capitan Silver Corp. acquired seven mineral concessions totaling 2,171.4 hectares adjacent to its Cruz de Plata project in Durango, Mexico, for US$4.0 million from Minera Fresnillo. This expands Capitan’s land position by 85% and extends the silver-gold trend by 1.2 km, enhancing infrastructure potential. The deal awaits approval from the Public Registry of Mines.

GR Silver Mining Ltd. announced promising results from its 2025 Step-Out Drilling Program at the San Marcial Area, Plomosas Project, Sinaloa, Mexico. Drill hole SMS25-08 intersected 19.9m at 250 g/t AgEq, including 1.3m at 954 g/t AgEq, and a new high-grade vein at 1,685 g/t AgEq. The program aims to expand the resource area, with ongoing drilling targeting further high-grade silver and gold mineralization.

Questcorp Mining Inc. has completed 25% of a 1200-1500m drilling program at its La Union Project in Sonora, Mexico, operated by Riverside Resources Inc. The program targets carbonate-hosted replacement deposit (CRD) style mineralization, focusing on gold in mantos, chimneys, and structural zones. This maiden drilling phase aims to evaluate four key areas, with potential for significant gold discoveries.

First Majestic Silver Corp. reported positive 2025 drilling results at its San Dimas Silver/Gold Mine in Durango, Mexico, highlighting significant gold and silver mineralization. Key intercepts include 15.93 g/t Au and 1,112 g/t Ag over 3.57m at Elia vein and 7.66 g/t Au and 495 g/t Ag over 5.17m at Sinaloa vein. The new Coronado vein discovery shows district-scale potential, reinforcing San Dimas as a cornerstone asset.
