Americas Gold and Silver Expands 034 Vein Complex with Discovery of Multiple New High-Grade Silver-Copper-Antimony Veins via Intercepts Including 4,458 g/t Ag, 3.34% Cu and 1.50% Sb Over 0.5M

Americas Gold and Silver (USA) has announced the expansion of the 034 Vein into a broader "034 Vein Complex" at its Galena operation in Idaho. Drilling has identified eight new high-grade silver-copper-antimony splay veins. Highlight intercepts include: * Hole 52-531: 5,225 g/t Ag, 3.51% Cu, and 3.42% Sb over 0.25m. * Hole 52-534: 4,458 g/t Ag, 3.34% Cu, and 1.50% Sb over 0.5m. * Hole 52-583: 5,443 g/t Ag, 5.04% Cu, and 4.19% Sb over 0.25m.

Management has released a conceptual exploration target for these splay veins of 550k-650k tonnes at 290-310 g/t Ag. This is in addition to the previously announced main 034 Vein target. The zone is near existing infrastructure, remains open, and is being evaluated for inclusion in the 2026 mine plan.

This news is Material - Positive from a geological and asset-value perspective, though investors must weigh this against the stock's massive recent appreciation. * Grade Validation: The reported silver grades (multi-kilogram per tonne) and significant antimony/copper by-products confirm Galena's status as a high-grade asset. The presence of antimony (up to 4.19%) is particularly strategic given the company's pivot to position itself as a critical minerals producer in the US. * Resource Expansion: Expanding a single vein into a "Complex" significantly increases the potential tonnage per vertical meter. The proximity to infrastructure is crucial; it implies these ounces can be brought into the mine plan (targeted for 2026) with lower capital intensity than developing new deep zones. * Operational De-risking: High-grade feed is essential for Galena to lower its unit costs, which have historically been high. These hits suggest the grade profile available to the mill could increase, improving margins. * Counter-balance: While the drill results are spectacular, the stock has risen from ~$1.75 to ~$9.21 in the last year. Much of this "blue sky" potential may already be priced in.

Americas Gold and Silver is a North American precious metals producer. * Flagship: Galena Complex (Idaho): A deep underground silver-lead-copper mine. Historically high-cost, but recent consolidation (100% ownership acquired Dec 2024) and high-grade discoveries (034 Vein) are central to the turnaround thesis. It is marketed as the only antimony producer in the US. * Growth Asset: Crescent Mine (Idaho): Recently acquired (Dec 2025) for $20M cash + shares. Located 9 miles from Galena, intended to provide high-grade feed to fill Galena's mill capacity. Restart targeted mid-2026. * Cash Cow/Stable Asset: Cosalá Operations (Mexico): Silver-zinc-lead mine. Currently transitioning to the EC120 silver-copper zone to improve margins.
