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.

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.

Avino Silver & Gold Mines Ltd. reported assay results from four drill holes at La Preciosa, targeting the La Gloria and Abundancia veins. Highlights include hole PMLP 25-03 with 1,638 g/t Ag and 1.92 g/t Au over 7.90m true width, and hole PMLP 25-04 with 544 g/t Ag and 0.46 g/t Au over 6.42m. The results confirm high-grade mineralization, exceeding resource expectations, and support further drilling to expand the resource. The veins show typical epithermal characteristics, with no notable copper. Assays followed strict QA/QC protocols at SGS Laboratory in Durango.

Advance Metals Limited completed its maiden diamond drilling program at the Yoquivo Silver-Gold Project in Chihuahua, Mexico, with significant results. Hole YQ-25-007 intersected 7.6m at 116 g/t AgEq, including 1.11m at 2,063 g/t AgEq (1,556 g/t Ag, 6.6 g/t Au), extending high-grade mineralization 60-70m down dip. Scoping holes YQ-25-005, 006, and 008 also hit high-grade structures north of the existing resource, with assays up to 649 g/t AgEq. The company is updating the geological model to guide future exploration and potential JORC resource upgrades.

Tocvan Ventures Corp. has secured a permit for a 50,000-tonne pilot mine facility at its Gran Pilar Gold-Silver Project in Sonora, Mexico, enabling processing of high-grade zones with a target of 1.2 g/t gold and 70% recovery. Combined with permits for 30,000 meters of drilling and 67 trenches, the project is advancing toward production, supported by strong metallurgical results (up to 99% gold recovery) and recent high-grade drill intercepts, including 6.1m at 5.4 g/t Au.

Silver Tiger Metals Inc. announced preliminary results from its 2025 Summer Exploration Program at the El Tigre Project in Sonora, Mexico. The program focuses on mapping and sampling the Northern Veins, 2 km north of the historic El Tigre Mine, to define drill-ready targets for Q4-2025. Exploration will also target undrilled Southern Veins, aiming to expand the project’s 25 km of mapped vein strike length.

Zacatecas Silver Corp. launched a 4,000-metre diamond drill program at its Zacatecas Silver Project, targeting El Cristo and Panuco North vein systems. The program aims to expand the 20.5 Moz AgEq resource at Panuco and explore El Cristo’s high-grade potential. A $2.5M private placement will fund drilling and growth initiatives.
