EV Resources has outlined a 10–12 month pathway to production at its Tecomatlán antimony processing plant, while reporting encouraging metallurgical and drilling results from the Los Lirios project. The company is advancing permitting, third-party ore supply agreements, and Phase 2 drilling to support its strategy of becoming a near-term North American antimony producer.
Luca Mining reported a new high-grade breccia discovery at its Tahuehueto Mine in Durango, with drilling returning 4.7 metres grading 6.7 g/t gold equivalent. The intercept expands mineralization below existing workings, highlighting strong potential for near-mine resource growth and supporting future mine plan expansion.
Silverco Mining reported strong underground drill results from the Promontorio zone at its Cusi Project in Chihuahua, highlighted by 1,100 g/t silver over 10.3 metres, including 6,452 g/t AgEq over 0.7 metres. The results confirm wide, high-grade mineralization and suggest significant vertical exploration potential, supporting the planned restart of mining operations.
Pacifica Silver completed its first 31.6-kilometre IP-resistivity survey at the Claudia silver-gold project in Durango, identifying a large, near-surface chargeability anomaly known as the “Judy” target. Encouraged by the results, the company has redeployed a drill rig to test the new target with an initial five-hole program while advancing its ongoing Phase II drilling campaign.
Capitan Silver reported additional high-grade drill results from its 60,000-metre program at the Cruz de Plata project in Durango, with all eight holes intersecting silver mineralization. Highlights include 1,077.1 g/t AgEq over 1.1 m within 6.7 m grading 342.2 g/t AgEq, extending the Jesús María trend at depth. Assays from 61 additional holes are pending.
Southern Silver reported high-grade underground channel sampling results from the Puro Corazon Mine at its Cerro Las Minitas Project in Durango, including 2.8 m of 757 g/t AgEq and 3.2 m of 479 g/t AgEq. The results support resource expansion as the company advances infill drilling, an updated resource estimate, and a revised PEA.
Talamore’s updated Cristina resource in Chihuahua comprises 17.5 Mt indicated at 1.41 g/t AuEq, containing 795,000 AuEq oz, and 33.0 Mt inferred at 1.17 g/t AuEq, containing 1.243 Moz. Versus 2023, contained AuEq increased 6% in indicated and 62% in inferred resources. Four mineralized vein systems remain open.
EV Resources continues to advance its 70%-owned Los Lirios Antimony Project in Oaxaca, where underground channel sampling has returned antimony grades of up to 25.2% Sb. The company has since defined a maiden exploration target of 1.8–5.0 Mt containing 70,000–166,000 tonnes of antimony and is preparing a Phase 2 drill program aimed at delivering a maiden JORC resource estimate in 2026.
First Majestic Silver has received construction permits for the Santo Niño and Navidad portals at its Santa Elena mine in Sonora and will invest an additional US$12 million in 2026 to advance underground development. Strong infill drilling continues to expand high-grade silver-gold mineralization, supporting near-term mining and extending the district’s mine life.
Heliostar Metals reported exceptional drill results from the Ana Paula gold project, including 99.8 metres grading 10.9 g/t gold, while expanding the high-grade Expansion Zone. Mineralization remains open in multiple directions, supporting further resource growth. The company has completed 32,678 metres of drilling and remains on track to deliver a feasibility study in Q2 2027.
