Americas Gold and Silver Corporation (TSX: USA) (NYSE American: USAS) has announced high-grade silver-copper drill results from its largest-ever exploration and mineral resource conversion drilling program at the Galena Complex in Idaho's Silver Valley. The program has delivered new vein discoveries at both the Galena and Crescent mines, with infill intercepts regularly exceeding grades modelled in the existing mineral resource. The results were not included in the company's 2025 Mineral Resource and Reserve statement, suggesting material upside to future mine planning.

Key Points

  • Americas Gold and Silver Corporation (TSX: USA) (NYSE American: USAS) operates the Galena Complex in Idaho, one of the United States' premier silver mining districts
  • 88 drillholes reported at Galena and Coeur mines; 12 of 45 Crescent holes reported, with 33 pending final assays
  • New vein discovered on the 49 level at Galena grading 1,061 g/t Ag, 0.7% Cu and 0.6% Sb over 1.2 metres; 9 Vein returned 7,123 g/t Ag, 3.24% Cu over 0.4 metres
  • Investors may be watching for remaining Crescent assay results and the planned 2027 updated mineral resource estimate

New Vein Discoveries and Standout Intercepts Across the Galena Mine's Operating Levels

The Galena Mine's 2026 drill program has identified a new high-grade vein on the operating 49 level, with hole 49-817 returning 1.2 metres of 1,061 g/t Ag, 0.7% Cu and 0.6% Sb. The 9 Vein, originally crosscut during utilities drift development in Q3 2026, returned 0.4 metres of 7,123 g/t Ag, 3.24% Cu and 1.81% Sb — discovered in an area with no prior drilling or vein projections. The company states approximately 85 metres of successful drifting has since been completed along the vein's strike, with drill bays established to further define its scale. Other notable intercepts include hole 37-336 returning 0.4 metres of 3,608.0 g/t Ag and 0.8 metres of 3,054.4 g/t Ag.

Coeur Mine's 520 Vein System Continues to Expand in Multiple Directions

At the adjoining Coeur Mine, the 520 Vein system has grown substantially, with hole C034-188 expanding the zone an additional 45 metres up-dip of the prior hole C034-166. The combined vein now measures 200 metres along strike and 200 metres in vertical extent, with all directions reported as remaining open for further expansion. The release states this 2025 discovery has been materially extended through the current program, adding potential to a mine that the company describes as being at restart stage. Chairman and CEO Paul Andre Huet noted that all 2026 Galena drilling has focused above the 6,000-foot level, with neighbouring mines extending beyond 10,000 feet.

Crescent Mine Infill Drilling Confirms Historical Veins and Uncovers Two New Structures

At the Crescent Mine project, 45 surface and underground core holes have been completed as part of a program designed to support mine planning ahead of a targeted 2027 mining start and an updated mineral resource estimate. Of the 12 holes reported, holes SF-002 and SF-003 intersected two new veins near the Alhambra vein, returning 1.1 metres of 1,109.5 g/t Ag and 0.8 metres of 939.3 g/t Ag respectively. Holes SF-014 and SF-017 intersected additional new vein material, with SF-017 returning 0.2 metres of 3,514.7 g/t Ag. The remaining 33 holes are pending final assay results.
