Questcorp Mining and Riverside Resources announce a new Carlin-like gold discovery at the Luis Hill target on the Union Project, Sonora, Mexico. Initial drilling hit 42.7m @ 0.286 g/t Au in black shales and carbonates. Famosa Mine area returned 1.85m @ 0.345 g/t Au. Phase I completed 12 holes (1,625m); assays pending for other targets. Follow-up drilling planned for 2026.

Mercado Minerals Ltd. has begun its first field exploration at the Copalito Project in Sinaloa, Mexico, including mapping, prospecting, re-sampling historic core, re-logging, and refining drill targets. The company aims to start a ~3000 m Phase 1 diamond drill program in Q1 2026 and will verify historical data while advancing logistics for drilling.

Kingsmen Resources Ltd. reported a new high-grade silver discovery at its Las Coloradas project (Parral district, Chihuahua, Mexico). Drill hole LC-25-004 hit 3.15 m at 241 g/t silver equivalent, including 1.15 m at 525 g/t AgEq and 0.185 g/t gold, from shallow depths. The DBD zone shows strong potential with further drilling planned.

Kingsmen Resources reported a new high-grade silver discovery at its Las Coloradas project in Chihuahua, Mexico. Drill hole LC-25-004 intersected 241 g/t silver equivalent over 3.15 m, including 525 g/t AgEq over 1.15 m, from a shallow depth (~70 m), with additional anomalous gold and strong mineralization suggesting further discovery potential and plans for more 2026 drilling.

Pinnacle Silver and Gold reports strong progress at its El Potrero gold-silver project in Durango, Mexico after acquiring up to 100 % of the property. In 2025 it established a large, high-grade epithermal system, completed extensive sampling and geological work, advanced metallurgy and permitting, and now plans underground and surface drilling in 2026 to advance toward production.

Pinnacle Silver and Gold Corp. reported strong progress at its El Potrero gold-silver project in Durango, Mexico, defining a large low-sulphidation epithermal system over ~1.6 km. Extensive mapping and sampling returned high-grade results, supporting planned underground drilling, metallurgy, and permitting as the project advances toward the next exploration stage.

Luca Mining Corp. reported strong drill results at Campo Morado, including 55.8 m of 5.90 g/t AuEq (with 7.7 m of 10.09 g/t) in hole CMRF25-15, confirming wider, higher-grade gold-rich mineralization near infrastructure. The company has expanded the program, adding a second rig and 10,000 m of drilling to test high-priority targets.

Pacifica Silver Corp. launched a 12,000m Phase II diamond drill program at its Claudia Silver-Gold Project in Durango, Mexico, starting January 15 with three rigs. Following the completed 7,992m Phase I, it will expand high-grade zones and test new southern targets, backed by ongoing exploration including mapping, LiDAR, and IP surveys.

Algo Grande Copper has confirmed its Adelita project in Sonora as a large porphyry-skarn system and identified 32 high-priority copper-gold-silver targets using integrated data and AI models. The company has begun a high-definition ground magnetic survey and appointed João Rocha as VP of Exploration to lead technical efforts, while drilling continues at Cerro Grande.

Regency Silver Corp. reports drill hole REG 25-26 intersected sulphide-specularite breccia over ~240m, extending the target 225m up-dip toward the historic Dios Padre silver mine in Sonora, Mexico. Breccias resemble prior high-grade Au-Cu-Ag zones; assays pending.
