AMERICAS GOLD AND SILVER REPORTS HIGH-GRADE 149 VEIN EXTENSION INCLUDING 24,913 G/T SILVER AND 16.9% COPPER AT GALENA COMPLEX AND EFFECTIVE DATE OF SHARE consOLIDATION

Americas Gold and Silver Corp. has released exploration results at the Galena complex, highlighting the identification of a high-grade upper extension of the 149 vein.

The company is also pleased to report that its previously announced share consolidation has been effected and trading on a postconsolidation basis is expected to occur starting with the open of trading on Aug. 26, 2025, on the basis of one postconsolidation common share of the company for every 2.5 preconsolidation common shares.

Paul Andre Huet, chairman and chief executive officer, commented: "The identification of this high-grade copper-silver-antimony extension to the 149 vein is an exciting development that builds on our ongoing success in unlocking additional value at the Galena complex. With some extraordinary intercepts, including 24,913 grams per ton silver over 0.21 metre and nearly 120 metres of vertical continuity demonstrated above the current mining level and exceptional grades in the intercepts, this extension positions us to potentially expand production from an already high performing vein. It aligns with our targeted exploration strategy to enhance mill feed quality and operational efficiency, supporting our goals of increasing output and shareholder value.

"We are also pleased with the completion of the share consolidation, which represents a strategic move to strengthen our capital structure. By reducing the number of outstanding shares, the consolidation maintains shareholder value and opens the doors to institutional investors with minimum price thresholds. It also potentially unlocks access to margin accounts at certain brokerages. Our leadership team successfully executed a 1-to-4.5 consolidation at Karora Resources in 2020, which saw the daily trading value triple over four years, demonstrating our experience with such initiatives, though past performance is not indicative of future results. This consolidation positions Americas for future growth as we continue to advance our high-potential assets."

High-grade extension of 149 vein uncovered by exploration drilling at Galena complex, highlighted by 24,913 g/t Ag and 16.9 per cent Cu over 0.21 metre

Recent early stage exploration drilling on the 4300 level from the 43-191 DDS at the Galena mine has identified a high-grade copper-silver-antimony vein believed to be the upper extension of the previously identified 149 vein. The three holes drilled to date demonstrate nearly 120 metres of vertical continuity above current mining level with more drilling in progress to infill and extend this vein. The 149 vein is currently being mined below these intercepts, producing a consistent high-grade mill feed of 600 to 700 tons per cut that average 700 to 950 silver grams per ton and 0.6 to 0.7 per cent copper. The 149 vein is a strong candidate currently under review for long hole open stoping.

The geologic setting and host rock interpretation indicates that recent intercepts are near the upper crown of the 149 vein. This area is located within the transition zone of the Upper Revett and the St. Regis formations, the two dominant Belt supergroup formations seen at the Galena mine. To date, 4,878 metres have been drilled from this station out of a planned 18,100 metres, testing several different targets in addition to the 149 vein.

Drill results on the 149 vein to date are:

• DDH 43-317: 24,913 grams per tonne Ag and 16.9 per cent Cu over 0.21 metre;
• DDH 43-304: 2,816 g/t Ag, 2.0 per cent Cu and 1.05 per cent Sb (antimony) over 1.05 metres;
• DDH 43-316: 2,354 g/t Ag and 1.7 per cent Cu over 1.58 metres.

Antimony (Sb) results are currently pending on holes 43-316 and 43-317.

These intercepts underscore the high-grade nature of the 149 vein extension, with potential to contribute to near-term mining plans and further resource delineation as additional drilling progresses. The vein remains open for expansion, and ongoing efforts will focus on infilling and testing adjacent targets to maximize its contribution to the Galena complex's production profile.

Share consolidation

Further to the announcement included in its news release dated Aug. 11, 2025, the company has filed articles of amendment, effective Aug. 21, 2025, to effect the previously announced consolidation on the basis of one postconsolidation common share for every 2.5 preconsolidation common shares.
