Masivo Silver Corp. (TSXV: MASS) is mobilizing crews and heavy equipment at its Cerro Colorado silver-gold project in Sonora, Mexico, for Phase I drilling. With environmental approvals secured, activities include rehabilitating access routes, building drill pads, and preparing high-priority targets. CEO David Coburn calls it a potential “company-making” moment for transformational discovery.

Luca Mining (TSX-V: LUCA) reported first drill results in over 14 years from El Rey deposit at Campo Morado, Mexico: 28.6 m @ 5.35 g/t AuEq (incl. 2.8 m @ 12.55 g/t) and 21.0 m @ 6.13 g/t AuEq (incl. 2.2 m @ 25.38 g/t). High-grade zones near infrastructure suggest potential mine life extension.

Minaurum Silver Inc. (TSXV: MGG, OTCQX: MMRGF) announced an initial Inferred Mineral Resource Estimate at its 100%-owned Alamos Silver Project in Sonora, Mexico: 5.37 Mt grading 320 g/t AgEq (202 g/t Ag, plus Au, Cu, Pb, Zn), containing 55.2 Moz AgEq. Based on 104 drill holes across three vein zones; resource remains open with ongoing Phase II drilling. Effective January 8, 2026.

Regency Silver reports that a second drill hole at its Dios Padre project in Sonora, Mexico intersected broad zones of sulphide-specularite breccia, supporting its geological model. This follows earlier holes showing similar mineralized breccias, and further drilling is underway to delineate the extent of the system.

Mercado Minerals Ltd. (CSE: MERC) started geophysical surveys at Copalito Project, Sinaloa, Mexico: high-resolution drone magnetic survey (1,885 ha, 50m lines) to map veins/drill targets, followed by drone LiDAR survey (1,867 ha) for detailed topography. Magnetic survey underway; LiDAR begins early February.

Colibri Resource finished its Phase 1 reverse circulation drilling at the San Perfecto and Banco de Oro targets within the El Plomo (EP) Gold Project in Sonora, Mexico. Initial assay results from pre-holiday holes have been received, with follow-up “shoulder” sampling in progress and remaining samples being prepared for lab analysis.

Southern Silver Exploration reported drill results from the Puro Corazon claim at its Cerro Las Minitas project in Durango, Mexico, including 15.3 m @ 581 g/t AgEq and 22 m @ 426 g/t AgEq, extending high-grade mineralization to ~235 m depth. Results will feed into an updated Mineral Resource Estimate and revised PEA as assays continue.

Sierra Madre Gold & Silver secured land-use authorization for its Tlacotal property at the La Guitarra silver-gold complex (Estado de México), enabling mining and development. The company also expanded land holdings, including areas near the tailings facility, supporting future expansion and planned 2026 drilling.

Continued drilling at the La Preciosa silver-gold project in Durango, Mexico delivered high-grade intercepts, including significant silver and gold values over meaningful widths. Results expand known mineralization and support ongoing exploration, guiding future drilling to further define and grow the resource potential.

Silver Dollar Resources outlined 2026 exploration plans at its 100%-owned La Joya Silver (Cu-Au) Project in Durango, Mexico, shifting focus toward higher-grade underground targets. The company has defined five priority drill targets to test deep San Martin-style mineralization, continues detailed mapping/sampling, and is fully funded to begin drilling once targeting is finalized.
