Luca Mining reported new high-grade drill results at its Tahuehueto mine in Durango, including 6.8 m grading 5.5 g/t gold equivalent, confirming mineralization continuity near existing workings. The results expand known high-grade zones and highlight strong potential for resource growth and near-mine expansion as ongoing drilling targets additional extensions.

Questcorp Mining and Riverside Resources reported high-grade gold-silver and polymetallic results at the La Unión Project, including 30 m of 20.2 g/t gold and 226 g/t silver, plus a new sediment-hosted gold discovery (42 m at 0.3 g/t Au). With a fully funded Phase 2 program underway, work is refining targets and advancing toward summer 2026 drilling.

Riverside Resources reported high-grade gold, silver, and base-metal assays from Phase 2 fieldwork at its La Unión Project in Sonora, including strong channel samples at Union Mine and Union Norte. Results confirmed robust CRD-style mineralization, identified three new targets, and refined drill targets ahead of a fully permitted summer 2026 drilling program.

EV Resources announced that its Tecomatlán processing plant in Puebla has reached operational readiness, with the grinding circuit entering dry commissioning. This milestone marks the transition from refurbishment to execution, significantly reducing technical risk and advancing the project toward near-term antimony production, with first output targeted by the end of 2026.

J2 Metals reported grab-sample results up to 845.4 g/t AgEq from historic workings at its Sierra Plata Project in Zacualpan, Mexico. The company advanced mapping, geochemical sampling, geophysics planning and drill permitting, and appointed Carlos Cham Dominguez, CPG, with nearly 20 years’ Taxco-district experience, as Mexico Country Manager.

Torex Gold reported encouraging Q1 2026 drilling results at its Morelos Complex, confirming continuity of high-grade mineralization at ELG Underground and identifying new high-grade structures. Results support resource expansion near Media Luna and efforts to replace reserves, reinforcing the project’s long-term growth potential and extending mine life through ongoing exploration.

EV Resources reported continued progress during the March 2026 quarter, advancing its exploration portfolio with a focus on lithium, copper, and other battery metals. Key activities included project evaluations, permitting, and early-stage exploration work, while the company maintained a disciplined approach to capital management and strategic asset development.

Mercado Minerals reported high-grade results from the Copalito Project in Mexico, including 6.5 m averaging 256 g/t silver and 1.46 g/t gold from shallow depths at the 5 Señores vein. The results confirm strong near-surface mineralization and support ongoing exploration targeting additional high-grade zones within a growing district-scale silver-gold system.

Luca Mining reported strong underground drilling results at its Campo Morado mine in Guerrero, highlighting thick, high-grade polymetallic intercepts in the unmined Largo Norte zone. Key results include 118.2 m grading ~2.5 g/t gold, 78 g/t silver plus base metals. Drilling confirms continuity and expands mineralization, supporting potential resource growth and future mine planning for 2026–2028.

Mithril Silver and Gold reported strong progress at its Copalquin project, highlighting high-grade drill results (e.g., 2.75 m at 660 g/t AgEq) and expanding multiple target areas. The company remains well funded (A$10.8M cash, debt free) and is advancing district-scale exploration to grow resources and define additional high-grade zones ahead of ongoing drilling.
