Riverside Resources and Questcorp Mining completed an expanded aeromagnetic drone survey at the La Union Project in Sonora, adding 248 km of high-resolution coverage to refine drill targets ahead of the fully permitted 2026 drill program. The survey improved imaging of concealed structures associated with potential CRD and Carlin-style mineralization, while drill road and pad construction is now underway

GR Silver Mining reported its best drill results to date from the San Marcial area of the Plomosas Project in Sinaloa, highlighted by 45.1 metres grading 1,623 g/t silver, including 8.25 metres at 8,579 g/t silver in hole SMS26-04. The results significantly expand the high-grade silver system at depth and support the company’s ongoing 20,000-metre resource expansion drilling program ahead of an updated resource estimate planned for H2 2026.

Tocvan Ventures reported new surface sampling results from the newly identified Bojorquez target at its Gran Pilar Gold-Silver Project in Sonora, located 3 kilometers east of the Main Zone. Rock chip samples returned up to 1.5 g/t gold and 39 g/t silver, outlining a 1.2 km by 700 m mineralized target associated with magnetic anomalies and potential epithermal mineralization.

Capitan Silver Corp. reported strong drill results from its 60,000-metre 2026 program at the Cruz de Plata Project in Durango, Mexico, including 934.6 g/t silver equivalent over 1.3 metres within a broader interval of 157.3 g/t silver equivalent over 20.0 metres. The results expand the high-grade Jesus Maria Silver Trend at depth and along strike, while identifying additional mineralized zones and new exploration targets.

Sonoro Gold Corp. announced binding letters of intent to acquire 24 mineral concessions and earn up to a 51% interest in five additional concessions adjacent to its Cerro Caliche project in Sonora, Mexico. The expansion could increase the property to more than 9,400 hectares and support the development of a larger district-scale epithermal gold system.

Mithril Silver and Gold reported strong drill results from its Copalquin project in Durango, Mexico, including 9.65 metres grading 7.00 g/t gold and 370 g/t silver at Target 1. The results support expansion of the existing resource footprint ahead of an updated Mineral Resource Estimate planned for June 2026, while confirming continuity of high-grade mineralization across the district-scale project.

Tocvan Ventures reported more than 5,300 metres drilled at its fully funded 20,000-metre Gran Pilar drill program in Sonora, Mexico, with assays pending for 21 holes. The company identified historic underground workings along the El Mezquite trend, highlighting additional exploration potential. Tocvan also secured a long-term community agreement and ordered processing equipment for its fully permitted 50,000-tonne pilot mining facility.

Defiance Silver reported additional high-grade drill results from its Zacatecas Project, including 356 g/t silver and 2.15 g/t gold within a broader mineralized interval. The results extend known silver-gold structures, validate the geological model, and support the ongoing 10,000-metre drill program aimed at updating the project’s mineral resource estimate.

Capitan Silver reported final results from its property-wide airborne MT geophysical survey at the Cruz de Plata Project in Durango, Mexico. The survey supports the company’s model of a large-scale silver-rich mineral system, identified multiple new exploration targets along strike and at depth, and confirmed geological continuity exceeding 1.5 km below surface. Assays remain pending for 64 drill holes.

Silver Storm Mining announced the mobilization of underground development contractors MINPRO and Mexgeo at its past-producing La Parrilla Silver Mine Complex in Durango, Mexico, marking another major step toward a potential restart of operations in Q2 2026. The contractors will provide underground mine development services, with mobilization expected to be completed by the end of May.
