Oroco has started Phase 2 diamond drilling at its Santo Tomás copper project in northwestern Mexico to upgrade mineral resource classifications in the South Zone. The work follows recent financing and includes infill/confirmation drilling and complementary pre-feasibility study programs.
Heliostar Metals reported drill results from its Ana Paula project in Guerrero, Mexico, including a 25.45 m intercept grading 8.26 g/t gold (with 8.30 m at 19.99 g/t) in the first down-dip hole into the Expansion Zone. Multiple high-grade intercepts were also logged in the High Grade Panel, and all results will be used in an upcoming feasibility study update.
J2 Metals reported high-grade silver-gold results from waste-dump grab sampling at its Sierra Plata Project in Mexico. Highlights included 3,100 g/t Ag and 12.8 g/t Au at San Miguel and 878 g/t Ag and 0.905 g/t Au at El Sabino. Follow-up mapping, geochemistry, geophysics and drilling are planned.
EV Resources reports widespread, high-grade antimony at its Los Lirios project in Oaxaca, Mexico, with channel samples up to 30.2% Sb at the Lirios 2 East pit and strong results across Lirios 1 and Lirios 2. Multiple mineralisation styles along a 6 km structural trend support ongoing maiden diamond drilling to test depth and continuity.
GoGold Resources is progressing its Los Ricos South Project in Jalisco, Mexico, moving into execution with detailed underground mine and plant designs, ordering long-lead equipment, and selecting a Mexican contractor. Key engineering work — including SART plant and tailings facilities — is well advanced, aiming to be “shovel ready” once permits are secured.
Axo Copper began a multi-phase drill program at its recently acquired San Antonio gold project in Sonora, targeting resource expansion and new discoveries, with an initial ~25,000 m focused on the Sapuchi deposit and ~5,000 m on high-priority targets like El Tigre. At La Huerta (Jalisco), drilling continues to extend high-grade copper-silver mineralization, backed by recent assays.
GR Silver Mining Ltd. kicked off a 20,000-metre step-out drilling campaign at its San Marcial project in Sinaloa, Mexico, aimed at expanding the 2026 resource base and upgrading the silver-lead-zinc resource. Early holes are underway to test extensions of known mineralization, supporting future resource updates and growth drilling objectives.
Defiance Silver Corp. reported high-grade silver drill results from its San Acacio area at the Zacatecas Project in Mexico, with standout intercepts like 3.55 m @ 355 g/t Ag and 3.07 m @ 579 g/t Ag (including 0.55 m @ 2120 g/t Ag), within 2,553 m of drilling so far in a planned 10,000 m program that shows lateral and vertical continuity of mineralization.
Mercado Minerals Ltd. reported new vein discoveries at its Copalito Project in Mexico, with three newly identified vein areas and ongoing mapping, soil sampling, and drone magnetic/LiDAR surveys. Preparations continue for its first 3,000 m diamond drill program, and samples from the new veins are being sent for assay.
Silver Wolf has mobilized a diamond drill rig to begin a fully funded 3,000-metre, 13-hole drill program at its Ana Maria property in Durango, Mexico. The campaign uses AI-driven target mapping to refine drilling, will be done in two phases, and comes with new stock-option grants and a short digital marketing agreement.
