Heliostar Metals Ltd. reported successful drilling at the Truckshop stockpile at La Colorada Mine, Sonora, Mexico, with highlights including 10.7m at 1.81 g/t gold and 19.8m at 0.62 g/t gold. The results support the company’s strategy to maximize cash flow from low-cost stockpiles before expanding the Veta Madre and Creston pits. Next, drilling will target the El Dorado stockpile.
Questcorp Mining Inc. (CSE: QQQ) has launched the first phase of its work program at the La Union CRD project in Sonora, Mexico, targeting a 100% interest from Riverside Resources Inc. The program includes IP surveying, geological mapping, and sampling to optimize drill targets for a 1,500-meter drill program in Q3 2025, focusing on high-grade polymetallic mineralization.
President Sheinbaum explained why the open-pit mining ban proposed by former President Andrés Manuel López Obrador was withdrawn and announced she will continue the moratorium on new mining concessions. Permits for existing mines will be under environmental review, especially open-pit operations. Permits currently being granted address tailings and operational issues, not new projects.
Tocvan Ventures Corp. announced a 50,000-tonne pilot leaching facility design for its Gran Pilar Gold-Silver Project in Sonora, Mexico, spanning 1.76 hectares. The 2023 land acquisition expanded the project to 21 km². High-grade drilling results (e.g., 3.1m at 19.4 g/t Au) and 62% gold recovery from a 2023 bulk sample highlight its potential, with permitting and financing targeted for 2025.
Vizsla Silver Corp. advances its Copala test mine at the Panuco silver-gold project in Mexico, reaching 125 meters in the decline. The 10,000-tonne bulk sample will support backfill planning and resource conversion. The portal will serve as the main access for future mining, with the fully funded program on track for completion by year-end.
Advance Metals Limited announced strong initial results from its maiden diamond drilling at the Yoquivo Silver-Gold Project in Mexico. The first hole, YQ-25-001, intersected high-grade zones, including 4.42m at 446g/t AgEq and a 40.57m zone at 105g/t AgEq, not in the current Foreign Estimate. Drilling continues, with assays pending for three more holes.
IMPACT Silver Corp. announced new drill results from the Kena Vein South zone at its Guadalupe silver mine in Mexico. Drilling from Level 140 extended the zone northward, discovering nearby high-grade parallel and splay veins. The zone spans over 300m and remains open. New underground access is complete, with initial mining started and further drilling planned.
Capitan Silver Corp. signed a Letter of Intent to acquire seven mineral concessions (2,171.4 hectares) adjacent to its Cruz de Plata project in Durango, Mexico, from Minera Fresnillo for US$4M. This expands Capitan’s land by 85%, extends the silver-gold trend by 1.2 km, and enhances exploration and development potential. Closing is expected within 90 days, pending due diligence.
Orla Mining Ltd. announced the first underground Mineral Resource estimate for its Camino Rojo deposit in Zacatecas, Mexico, extending from the oxide open pit. The Measured and Indicated Resource totals 50.1 Mt at 2.58 g/t AuEq (4.16 Moz), with an Inferred Resource of 5.6 Mt at 2.33 g/t AuEq (0.42 Moz). Zone 22, a sulphide extension, contributes 7% and 19% to these categories, respectively. The resource supports heap leaching, cyanidation, and flotation with pressure oxidation. Orla plans further drilling, an exploration drift, and a 2026 Preliminary Economic Assessment to advance toward underground mining.
Odyssey Marine Exploration, Inc. (NASDAQ: OMEX) is advancing its phosphate project in Mexico and battery metal projects in the Cook Islands, supported by a U.S. Executive Order boosting seafloor mining.
