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

TORONTO, ONTARIO – August 22, 2025 – Americas Gold and Silver CorporaƟon (TSX: USA) (NYSE American: USAS)

(“Americas” or the “Company”), a growing North American precious metals producer, is pleased to announce

strong exploraƟon results at the Galena Complex, highligh Ɵng the idenƟficaƟon of a high-grade upper extension

of the 149 Vein.

The Company is also pleased to report that its previously announced share consolida Ɵon has been effected and

trading on a post-consolidaƟon basis is expected to occur star Ɵng with the open of trading on August 26, 2025,

on the basis of one (1) post-consolidaƟon common share of the Company (“Common Share”) for every two and a

half (2.5) pre-consolidaƟon Common Shares (the "ConsolidaƟon").

Paul Andre Huet, Chairman and CEO, commented: “The idenƟficaƟon of this high-grade copper-silver-an Ɵmony

extension to the 149 Vein is an exci Ɵng development that builds on our ongoing success in unlocking addi Ɵonal

value at the Galena Complex. With some extraordinary intercepts, including 24,913 grams per ton silver over 0.21

metres, and nearly 120 meters of verƟcal conƟnuity demonstrated above the current mining level and excepƟonal

grades in the intercepts, this extension posi Ɵons us to poten Ɵally expand produc Ɵon from an already high-

performing vein. It aligns with our targeted explora Ɵon strategy to enhance mill feed quality and opera Ɵonal

efficiency, supporƟng our goals of increasing output and shareholder value.

We are also pleased with the comple Ɵon of the share consolida Ɵon, which represents a strategic move to

strengthen our capital structure. By reducing the number of outstanding shares, the consolida Ɵon maintains

shareholder value and opens the doors to insƟtuƟonal investors with minimum price thresholds. It also potenƟally

unlocks access to margin accounts at certain brokerages. Our leadership team successfully executed a 4.5-to-1

consolidaƟon at Karora Resources in 2020, which saw the daily trading value triple over four years, demonstraƟng

our experience with such iniƟaƟves, though past performance is not indicaƟve of future results. This consolidaƟon

posiƟons Americas for future growth as we conƟnue to advance our high-potenƟal assets.”

High-grade Extension of 149 Vein Uncovered by Explora Ɵon Drilling at Galena Complex, Highlighted by 24,913

g/t Ag and 16.9% Cu Over 0.21 Meters

Recent early-stage exploraƟon drilling on the 4300 Level from the 43-191 DDS at the Galena Mine has idenƟfied a

high-grade copper-silver-anƟmony vein believed to be the upper extension of the previously iden Ɵfied 149 Vein.

The three holes drilled to date demonstrate nearly 120 meters of ver Ɵcal conƟnuity above current mining level

with more drilling in progress to in fill and extend this vein. The 149 Vein is currently being mined below these

intercepts, producing a consistent high-grade mill feed of 600-700 tons per cut that average 700-950 silver grams

per ton and 0.6-0.7% copper. The 149 Vein is a strong candidate currently under review for long hole open stoping.

The geologic seƫng and host rock interpretaƟon indicates that recent intercepts are near the upper crown of the

149 Vein. This area is located within the transiƟon zone of the Upper ReveƩ and the St. Regis FormaƟons, the two

dominant Belt Supergroup formaƟons seen at the Galena Mine. To date, 4,878 meters have been drilled from this

staƟon out of a planned 18,100 meters, tesƟng several different targets in addiƟon to the 149 Vein.

Drill results on the 149 vein to-date are:

• DDH 43-317: 24,913 g/t Ag and 16.9% Cu over 0.21 meters

• DDH 43-304: 2,816 g/t Ag, 2.0% Cu and 1.05% Sb over 1.05 meters

• DDH 43-316: 2,354 g/t Ag and 1.7% Cu over 1.58 meters

AnƟmony (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 potenƟal to contribute to near-

term mining plans and further resource delinea Ɵon as addi Ɵonal drilling progresses. The vein remains open for

expansion, and ongoing e fforts will focus on in filling and tesƟng adjacent targets to maximize its contribu Ɵon to

the Galena Complex's producƟon profile.

Share ConsolidaƟon

Further to the announcement included in its ne ws release dated August 11, 2025, the Company has filed arƟcles

of amendment, effecƟve August 21, 2025, to e ffect the previously announced Consolida Ɵon on the basis of one

(1) post-consolida Ɵon Common Share for every two and a half (2.5) pre-consolida Ɵon Common Shares. The

Common Shares are expected to commence trading under their exis Ɵng symbols on the Toronto Stock Exchange

and on the NYSE American on a post-ConsolidaƟon basis on the opening of trading on Tuesday August 26, 2025.

The Consolida Ɵon reduced the number of Common Shares issued and outstanding from approximately

679,357,056 to approximately 271,742,692. As a result of the Consolida Ɵon, shares issuable pursuant to the

Company’s outstanding stock op Ɵons, warrants, restricted share units, performance share units and other

converƟble securiƟes will be proporƟonally adjusted on the same basis.
