Americas Gold and Silver Completes First Phase of Upgrades on Galena No. 3 Shaft Ahead of Schedule Delivering 100% Productivity Improvement

Toronto, Ontario--(Newsfile Corp. - September 16, 2025) - Americas Gold and Silver Corporation (TSX:USA) (NYSE:USAS) ("Americas" or the "Company"), a growing North American precious metals producer, is pleased to announce that it has completed Phase 1 upgrades to increase the hoisting capacity of the No. 3 Shaft at its 100% owned Galena Complex, located in Wallace, Idaho. The Phase 1 upgrade, completed ahead of schedule, is part of a planned two-phase upgrade project on the No. 3 Shaft, and a key component of the Company's ambitious production growth strategy at the Galena Complex. The Phase 1 upgrade was completed during a 10-day shutdown period, four days shorter than planned.

Paul Andre Huet, Chairman and CEO, commented: "I am very pleased to announce that the first phase of the Galena No. 3 Shaft upgrade has been completed ahead of schedule, which is a tremendous outcome for our operations. I would personally like to thank and congratulate our team on a very successful upgrade period which was completed in just 10 days versus a planned 14 days.

"During the due diligence period prior to the new management team joining Americas, our team recognized the potential to substantially increase production from the Galena Complex and identified shaft upgrades as a critical element to our success. Upon completion of the upgrades on the motor, lilies, brakes, and introducing hoist-control automation, we expect to increase skipping times from the current 690 feet per minute to approximately 1,200 to 1,400 feet per minute and increase our skipping capacity from approximately 40 tons per hour to approximately 100 tons per hour. I am very excited to say that in just our first few days of operating the upgraded hoist, we have already reached 80 tons per hour which is a 100% improvement on our existing skipping capacity. This will enable us to move a significantly larger amount of tons from our operation while we continue to set up the mine for increased long hole stoping next year. Very importantly, we now have a spare 2,250 hp hoist motor for our primary No. 3 shaft for the first time, providing critical backup capacity and derisking our mine plan.

"The Galena team continues to execute on our overall strategy of increasing the safety and efficiency of the Galena mine by delivering projects ahead of plan and under budget while continuing to operate the mine safely and hit our production targets. We look forward to updating our stakeholders on the second phase of the No. 3 Shaft upgrades before the end of the year."

Galena No. 3 Shaft Upgrade Project

The No. 3 Shaft upgrade project is expected to increase hoisting capabilities from approximately 40 tons per hour (tph) of material to 100 tph. These upgrades will remove a key bottleneck and boost overall mine productivity and cost efficiencies by the end of 2025. In the first few days of operating the new hoist, the first phase has enabled an increase to 80 tons per hour of material movement.

Highlights completed during Phase 1 of the two-phase project included:

• Upgraded the No. 3 Hoist motor from 1,750 hp to 2,250 hp, enabling full skips to be pulled from the deepest level in the mine (5600L) — a substantial improvement over the prior capacity of half to three-quarter full skips.
• Installed a second 2,250 hp spare motor significantly derisking operations by providing backup capacity.
• Installed weight measuring systems on the skips, which will optimize hoisting efficiencies.

Phase 2 upgrades are scheduled to begin before the end of the year with a planned duration of approximately 10 days and will include:

• Upgrading the hoist pads ("lilies") and braking system to increase creep times in loading and dump zones.
• Installing a new hoisting control console with advanced technology that will accommodate additional hoist automation in the future.
• Deploying an antenna system, known as a "leaky feeder" in the No. 3 Shaft to improve in-mine communications and support automation upgrades.
