Guanajuato Silver Company Ltd. reports high-grade vein intercepts at its San Ignacio Mine, Mexico, including 8.20m true width at 536 g/t AgEq and 1.06m at 2,585 g/t AgEq in the Santo Nino zone. Development work is underway to access these gold-rich areas for mining in 2025, leveraging existing infrastructure for rapid exploitation.

Heliostar Metals Ltd. will restart mining at San Agustin Mine in H2 2025, targeting 45,000 gold ounces from the Corner Area, with a post-tax NPV5% of US$35.25M, IRR of 548%, and CAPEX of US$4.2M at US$3,000/oz gold. Drilling in H2 2025 will focus on oxide and sulphide targets to extend mine life.

Oroco Resource Corp.’s subsidiary, Minera Xochipala, signed an option agreement with Aztec Zinc to acquire 100% of the Vainilla Mineral Concession in Sinaloa, Mexico, covering 2,974 hectares near the Santo Tomás Project. The concession hosts polymetallic mineralization, offering exploration potential for copper and related metals. Oroco plans a staged exploration program, including IP surveys, mapping, and drilling. The option involves cash and share payments, with a 1.5% NSR royalty upon exercise, pending TSX-V approval.

Torex Gold Resources Inc. reported strong drilling results from the EPO deposit’s northern extension at the Morelos Complex, Mexico. Highlights include 55.18 gpt AuEq over 20.1 m (ML24-1049DA) and 6.17 gpt AuEq over 15.0 m (ML24-1048D). The 2024 program added 233,000 oz AuEq to Inferred Resources. Drilling aims to expand resources and extend production beyond 2035, with first EPO production expected by late 2026.

Minaurum Gold Inc. announced high-grade silver results from the Promontorio Sur vein zone at its Alamos Silver Project in Sonora, Mexico. Drilling intersected 1.05 m of 272 g/t AgEq and 4.95 m of 174 g/t AgEq, indicating potential for deeper high-grade mineralization. The 1.5 km-long zone, part of the 3.5 km Promontorio-Quintera trend, remains a significant exploration target.

Kingsmen Resources Ltd. signed a non-binding LOI to acquire the Almoloya gold-silver project in Chihuahua’s Parral Mining District, 30 km from its Las Coloradas project. Covering 866.25 hectares, the consolidated claims target epithermal and CRD deposits. Historical production at Cigarrero Mine yielded 1.25M tonnes at 600 g/t Ag.

GR Silver Mining Ltd. reports high-grade silver results from Phase I underground sampling at Plomosas Mine, Mexico, with up to 3,993 g/t Ag Eq. The program aims to model high-grade zones, collect metallurgical data, and support a Bulk Sampling Test Mining program. Phase II will refine engineering plans, leveraging existing permits and infrastructure for potential 2026 implementation.

IMPACT Silver Corp. announced new drill results from the Juarez Zone at its Plomosas zinc-lead-silver mine in Mexico, with high-grade intersections including 30.10% zinc, 7.88% lead, and 61.8 g/t silver. The mineralization, outside existing JORC resources, is near underground infrastructure, enabling rapid mining expansion. Drilling continues to expand resources, leveraging the mine’s high-grade potential.

Luca Mining Corp. announced high-grade results from its 2025 drilling program at the Campo Morado mine, Mexico. Surface drillhole CM-RF-25-001 at Reforma Deposit hit 15.1m of 11.9 g/t AuEq, while underground drillhole CMUG-25-015 yielded 4.5m of 12.2 g/t AuEq. The 7,500m Phase 1 program targets resource expansion, with 22 underground and 5 surface holes completed, aiming to update mineral resources and mine plans.

Riverside Resources and Questcorp Mining are preparing for the first-ever drill program at the Union Gold-Silver Project in Sonora, Mexico, targeting high-priority Carbonate Replacement Deposit (CRD) zones. The 1,500-meter diamond drilling will test Union, North Union, and Famosa zones, which historically produced 50,000 ounces of gold equivalent. Recent geophysical surveys, including IP and drone magnetics, along with surface geochemistry, have refined drill targets, showing significant potential for gold and base metal discoveries.
