Riverside Resources Inc. reports the Union Project drill program in Sonora, Mexico, advancing on schedule and budget. Three of five targets (Union Mine, El Cobre, North Union) tested, revealing promising hematitic oxides and quartzite. Drilling now at high-potential Famosa target; assays pending. Insights refine exploration model for CRD gold mineralization.

Colibri Resource (TSXV: CBI) partnered with TerraEye to apply satellite remote sensing and AI at the EP Gold Project in Sonora, Mexico. The program will integrate spectral, structural, and geochemical data to deliver ranked gold targets, GIS-ready packages, and analytical reports, aiming to refine drill planning, reduce discovery risk, and expand Colibri’s exploration pipeline.

Kingsmen Resources reports high-grade silver discovery at Las Coloradas project, Mexico. Hole LC-25-010 intersected 1,028 g/t AgEq over 1.45m (incl. 1,742 g/t over 0.70m) and 138 g/t AgEq over 13.35m at shallow depths below historic mines. Significant untapped potential; awaiting 11 more hole assays.

Regency Silver Corp. has contracted Bylsa Drilling for a 4500m program at Dios Padre, targeting high-grade Au-Cu-Ag extensions. Drill arrives by Sept 25, 2025; permits and pads ready. Previous intercepts include 38m at 7.36 g/t Au. CEO excited about expansion.

Southern Silver Exploration Corp. acquires Puro Corazon mining claim, contiguous to Cerro Las Minitas, from arms-length vendor via cash payments over 40 months. The claim mines 60 tonnes/day of silver-lead-zinc concentrates. Plans: 12,000m infill drilling, updated PEA in Q1 2026 for resource growth and enhanced economics.

Colibri Resource Corp. updates on advancing its 100%-owned EP Gold Project in Mexico’s Caborca Belt and 49% stake in Pilar Gold-Silver JV. Amid high metal prices, plans include exploration drilling, pilot mining, resource estimate, PEA, and financing to enhance shareholder value.

Tocvan Ventures Corp. announces the start of field work and airborne magnetics survey at its flagship Gran Pilar Gold-Silver Project in Sonora, Mexico. This advances exploration with geological mapping, sampling, and geophysics, paving the way for imminent drilling, trenching, and pilot mining under a 10-year permit.

Fortuna Mining (FSM) updates $19M generative exploration: Guiglo (Côte d’Ivoire) shows 5km gold anomaly; Tongon North advances targets; Centauro (Mexico) preps drill for epithermal system; La Carmen maps alteration; Cerro Lindo (Argentina) prospective for HSE gold-silver; Arizaro yields intercepts like 0.59 g/t Au, 0.29% Cu over 46m.

Saf Dhillon, President and Chief Executive Officer, states: “The drilling is indicating oxidation is consistent with past mining and targets are coming along with a positive exploration drilling so far. The drilling is intersecting more quartzite than expected which is favorable for fracture-controlled mineralization.” Drilling has now moved to the Famosa Target to progress exploration program.

“As at the historic Pinos Cuates mine, the existing underground workings at Dos de Mayo are giving us an important understanding of the nature of the gold-silver mineralization at El Potrero,” stated Robert Archer, Pinnacle’s President & CEO. “What we are seeing is consistent with these low-sulphidation epithermal systems, where pockets of high-grade mineralization (called “clavos” in Mexico) occur within a defined horizon, likely consistent with the “boiling zone” of the hydrothermal fluids.
