Guanajuato Silver (GSilver) is acquiring Endeavour Silver’s Bolanitos mine in Guanajuato, Mexico for up to US$50M (US$40M upfront + US$10M contingent). Bolanitos, producing ~2.5M AgEq oz in 2024, becomes GSilver’s 5th mine, integrating San Ignacio for cost savings and adding Cebada project. Deal closes January 2026.

Heliostar Metals reports high-grade gold intercepts from Ana Paula drilling in Mexico, including 83.2m at 17.35 g/t Au (46.65m at 27.35 g/t), 70.7m at 9.38 g/t, 92.1m at 4.33 g/t, and 65.2m at 5.39 g/t. Program expanded 33% to 20,000m for resource conversion and exploration, supporting feasibility study with low $1,011/oz AISC.

Advance Metals (ASX:AVM) has recommenced diamond drilling at its 100% owned high-grade Yoquivo Silver-Gold Project in Chihuahua, Mexico. The fully funded ~3,000m program targets depth and lateral extensions to the existing 17.23Moz AgEq (570 g/t) Foreign Estimate at Pertenencia, plus new high-grade regional veins (up to 1,594 g/t AgEq at surface). Drilling continues into early 2026, supported by historic core resampling, to deliver an upgraded JORC resource.

IMPACT Silver (TSXV:IPT) reported high-grade zinc intercepts from underground drilling at the Juarez Zone, Plomosas mine, Mexico. Highlights include 2.15m at 22.1% Zn, 3.3% Pb, 19 g/t Ag and 1.15m at 28.1% Zn, 4.1% Pb, 22 g/t Ag. All intercepts outside existing resources; zone remains open. Two drills active on near-mine extensions.

GR Silver Mining (TSXV: GRSL) reported step-out drill results from San Marcial, Plomosas Project, Mexico. Hole SMS25-12 extended high-grade silver mineralization 75m below the current resource, intersecting 5.0m @ 232 g/t Ag (incl. 0.9m @ 956 g/t Ag and 0.2m @ 2,602 g/t Ag) plus 8.8m @ 121 g/t Ag. Mineralization remains open at depth; further expansion drilling planned for H1 2026.

Kootenay Silver (TSXV: KTN) announced drill results from the first 7 holes of its 50,000m program at Columba Project, Mexico, revealing high-grade silver intercepts (up to 921 g/t Ag over 0.71m) on D Vein/I Vein plus a new discovery of broad porphyry-style gold zones (e.g., 101m @ 0.18 g/t Au; up to 0.85 g/t Au over 6m) with molybdenite, indicating potential for a separate gold-porphyry system. Drilling continues with plans to add rigs.

Silverco released additional drill assay results from its 2025 Cusi drill program in Chihuahua, Mexico, including standout intercepts like 3.4 m at 425 g/t AgEq and 1.5 m at 764 g/t AgEq, confirming strong high-grade silver-lead-zinc-gold mineralization. The results support continued potential expansion of the Cusi deposit and feed into an upcoming Mineral Resource Estimate update.

Defiance Silver completed a major trenching program at its San Acacio project in Zacatecas, Mexico, sampling 2.1 km of the Veta Grande vein. Results confirm strong surface continuity with highlights up to 5,180 g/t Ag and 4.85 g/t Au, supporting the upcoming mineral resource estimate.

Zacatecas Silver finalized land-access agreements for its El Cristo Target drill program at the Zacatecas Silver Project in Mexico, enabling full access to the 3km vein system. With SEMARNAT permits underway, the company aims to test high-grade silver extensions, building on prior results like 829 g/t AgEq over 0.65m.

Pinnacle Silver and Gold reported high-grade sampling at La Dura mine, El Potrero Au-Ag project, Mexico: 162 g/t AgEq over 12.48m, extending Dos de Mayo vein mineralization to 500m. New zone discovery with up to 4.51 g/t Au and 269 g/t Ag; undrilled potential for expansion.
