<div id="readability-page-1"><article>Toronto, Ontario--(Newsfile Corp. - January 20, 2026) - Americas Gold and Silver Corporation (TSX: USA) (NYSE American: USAS) (&#34;Americas&#34; or the &#34;Company&#34;) a growing North American precious metals and antimony producer, is pleased to announce strong exploration drilling results at the Galena Complex driving significant growth in the vicinity of the recently discovered high-grade 034 Vein (see Americas' news release dated April 22, 2025).Exploration diamond drilling from the 5200 Level of the Galena Mine, completed late in 2025, has defined eight new high-grade silver-copper-antimony splay veins associated with the 034 Vein. This area, known as the &#34;034 Vein Complex&#34;, is composed of a series of silver-copper-antimony veins adjacent to current infrastructure, presenting a near-term mining opportunity at Galena.Paul Andre Huet, Chairman and CEO, commented: &#34;Our team at Galena have delivered another very impressive discovery at our flagship operation. The identification of eight new high-grade silver-copper-antimony splay veins has grown the 034 Vein discovery last year into an entire complex of high-grade veins now called the 034 Vein Complex.Galena has a long and storied history of silver, copper, lead and antimony production and this new discovery is a true testament to the outstanding potential of Galena to continue to grow as one of the highest-grade silver operations globally. Importantly, the 034 Vein Complex remains wide open, providing exciting potential for additional growth right beside existing infrastructure and reinforcing our position as a premier U.S. silver and antimony producer.&#34;The 034 Vein was initially crosscut and drifted on from the 5200 Level. An exploration drill plan was designed, and 23 additional diamond drill holes (&#34;DDH&#34;) were drilled into the 034 Vein. Significant grades were intersected in both the hanging wall and footwall of the 034 Vein. The new splay veins were identified based on both current and historical drilling using veins identified in the core logging, a compilation of assay results, mapped geology above and below the vein complex as well as structural interpretation of the results. Key intercepts from the campaign, reported with true widths, are listed in Table 1 below:Table 1: Key Intercepts returned from recent drilling in the 034 Vein Complex<table><tbody><tr><td>Hole #</td><td>Width (m)*</td><td>Ag (g/t)</td><td>Pb (%)</td><td>Cu (%)</td><td>Sb (%)</td><td>Vein</td></tr><tr><td>52-520</td><td>1.17</td><td>1,777</td><td>0.15</td><td>1.03</td><td>0.80</td><td>034hw</td></tr><tr><td>52-528</td><td>0.72</td><td>2,067</td><td>0.08</td><td>1.79</td><td>1.58</td><td>034fw3</td></tr><tr><td>52-531</td><td>0.25</td><td>5,225</td><td>0.11</td><td>3.51</td><td>3.42</td><td>034hw</td></tr><tr><td>52-534</td><td>0.50</td><td>4,458</td><td>0.18</td><td>3.34</td><td>1.50</td><td>034hw2</td></tr><tr><td>52-581</td><td>1.01</td><td>1,046</td><td>0.13</td><td>1.73</td><td>0.69</td><td>034hw</td></tr><tr><td>52-583</td><td>0.25</td><td>5,443</td><td>0.10</td><td>5.04</td><td>4.19</td><td>034hw2</td></tr></tbody></table>*Note: Reported intercepts are estimated true widths.Based on the information to date, including 47 historic and recent drill intercepts, the 034 Vein Complex has potential economic continuity from the 5200 Level to the 5500 Level, representing a vertical extent of 100 metres. In addition, the 034 Vein Complex remains open both up-dip and at depth.Preliminary estimates of the eight new splay veins indicate an overall exploration target of 550-650k tonnes at 290-310 g/t silver, 0.20-0.30% copper, and 0.15-0.20% antimony (calculations based on the Company’s internal modelling completed on the 034 Vein Complex utilizing geologic parameters set out in the Company’s Mineral Resource and Reserve Statement dated December 31, 2024) . This is in addition to the previously announced exploration potential of the main 034 Vein (100-120k tonnes at 311-467 g/t silver and 0.31-0.40% copper (calculations based on the Company’s internal modelling completed on the 034 Vein Complex utilizing geologic parameters set out in the Company’s Mineral Resource and Reserve Statement dated December 31, 2024). Utilizing the reported assay results and extensive geological knowledge of the Galena Complex and its silver-copper veins, Americas’ geologists generated the estimated grade range stated above. The potential quantity and grade of the exploration target are conceptual in nature; at this stage, it is uncertain if further exploration drilling will result in the exploration target being delineated as a Mineral Resource.The 034 Vein Complex is crossed by current development on the 5200 and 5500 Levels (see Figure 1 below), presenting multiple mining opportunities that are in the process of being evaluated for addition to the 2026 mine plan.<div><img src="https://imageproxy.pbkrs.com/https://images.newsfilecorp.com/files/5082/280938_693990ba94c62b89_002.jpg?x-oss-process=image/auto-orient,1/interlace,1/resize,w_1440,h_1440/quality,q_95/format,jpg" width="550" height="310" original-src="https://imageproxy.pbkrs.com/https://images.newsfilecorp.com/files/5082/280938_693990ba94c62b89_002.jpg"/>Figure 1: (L) Long section view of the 034 Vein Complex in relation to the No. 3 and Galena Shafts; (R) Isometric view showing major faults, drill holes and the various 034 Splay Veins that make up the Vein Complex.</div>To view an enhanced version of this graphic, please visit: https://images.newsfilecorp.com/files/5082/280938_693990ba94c62b89_002full.jpgA full table of drill results can be found at: https://americas-gold.com/site/assets/files/4297/dr20260120.pdf.About Americas Gold and Silver CorporationAmericas Gold &amp; Silver is a rapidly growing North American mining company producing silver, copper, and antimony from high-grade operations in the U.S. &amp; Mexico.
