Southern Silver reported high-grade intercepts at its Cerro Las Minitas project in Durango, Mexico, including 5.8m averaging 781g/t AgEq (173g/t Ag, 1.5% Cu, 1.8% Pb, 17.3% Zn) in hole 25CLM-210. Additional strong results extend mineralization over 360m depth.
Advance Metals (ASX:AVM) announced historic core sampling at its Yoquivo silver-gold project in Chihuahua, Mexico, revealing resource upside. ~5,000m sampled, 3,516m assayed, with 519m >4g/t AgEq. Highlights: 0.9m at 766g/t AgEq (426g/t Ag, 4.4g/t Au); broad zones like 144m at 93g/t AgEq, suggesting bulk tonnage open-pit potential alongside high-grade underground, supporting upcoming JORC resource upgrade.
Mammoth Resources Corp. announced 87% gold and 67% silver recoveries from bottle roll tests on coarser (-10 mesh) oxidized material from the Carneritos area at its Tenoriba gold-silver property in Chihuahua, Mexico. Results align with prior finer fraction tests (75-90% Au, ~65% Ag), supporting strong heap leach potential for near-surface mineralization.
GR Silver Mining reported strong metallurgical results from Plomosas bulk sampling: feed ~585–595 g/t AgEq. Rougher flotation recovered 71.5% Ag and 77.9% Au into lead concentrate; cleaner tests improved Au recovery. Concentrates meet commercial specs. Supports pilot plant and offtake plans.
Algo Grande Copper Corp. discovered three new skarn horizons at the Adelita Project (Cerro Grande), Sonora, Mexico. Drill hole AG_GC_002 intersected 36.00m >1.0% Cu, including 14.79m @ 1.4% Cu (plus Au/Ag). Cumulative 41.59m mineralization reported. Evidence of deeper porphyry potential via intrusive phases and high molybdenum.
Heliostar Metals Ltd. announced the first gold pour from its restarted 100% owned San Agustin mine in Durango, Mexico, in late January 2026, completed on time and on budget after resuming operations in Q4 2025. The mine targets 30,000-32,700 oz gold in 2026 at ~$2,000 AISC, boosting output >60% yoy. A 10,000-15,000m drill program aims to extend mine life, with results expected mid-late Q1 2026.
Regency Silver Corp. announced that its third drill hole (REG-26-28) at the Dios Padre project in Sonora, Mexico, intersected broad zones of sulphide-specularite bearing breccia and mineralization from ~430m to ~540m depth, including a 35m zone with chalcopyrite, pyrite, and intense alteration. Drilling continues, showing continuity with prior holes (assays pending).
Silver Storm Mining has commenced expansion of the sulphide flotation circuit at its La Parrilla Silver Mine Complex in Durango, Mexico, increasing capacity from 1,000 to 1,250 tpd with eight new flotation cells delivered (two installed, others in Q1 2026). This supports a potential restart in Q2 2026.
Capitan Silver hit 1,130.1 g/t AgEq over 1.5 m within 240.5 g/t AgEq over 25.9 m at its Cruz de Plata silver-gold project in Durango, Mexico, as part of 2025 drilling that continues to expand high-grade zones and new targets. Ongoing 2026 drilling seeks to further define the system.
EV Resources commenced its maiden diamond drilling at the Los Lirios antimony project in Oaxaca, Mexico, with a 1,500–2,000 m program targeting high-priority zones toward a maiden resource. Surface samples returned up to 29% Sb. The company is fully funded and refining assay methods for high-grade antimony.
