Q1 2025 PRODUCTION HIGHLIGHTS

• Record Silver Production (+88% Y/Y): The Company produced 3.7 million silver ounces in Q1 2025 representing an 88% increase when compared to 2.0 million silver ounces produced in Q1 2024. Total silver production in the quarter included 1.4 million ounces of attributable silver production from Cerro Los Gatos as well as a notable 17% (0.2 million ounce) increase at San Dimas primarily due to operational improvements.

• Strong Silver Equivalent Production (+49% Y/Y): The Company produced 7.7 million AgEq ounces in Q1 2025 representing a 49% increase when compared to 5.2 million AgEq ounces produced in Q1 2024 driven by an 88% increase in attributable consolidated silver production and a 1% increase in gold production. The significant increase resulted from the inclusion of attributable production from Cerro Los Gatos, as well as an 11% increase in production at San Dimas.

• Continued Active Exploration Program: During the first quarter, the Company completed a total of 61,219 metres ("m") of drilling across its mines in Mexico. Throughout the quarter, up to 28 drill rigs were active consisting of seven rigs at Cerro Los Gatos, seven rigs at Santa Elena, 13 rigs at San Dimas, and one rig at La Encantada.

• Conversion to Liquefied Natural Gas ("LNG") at San Dimas: The replacement of the diesel generators used for on-site back-up power at San Dimas with LNG units is near completion, with four 1 megawatt ("MW") LNG generators on site that will commence operating in Q2 2025. We expect this shift to LNG to generate substantial cost-savings and will result in a reduction in carbon emissions of up to 25%, when back-up power is required.

• Record Safety Performance Continues (-65% Y/Y): The consolidated Q1 2025 Total Reportable Incident Frequency Rate ("TRIFR") was 0.17, well below the Company's 2025 target KPI of 0.70 and a 65% improvement compared to Q1 2024. The Lost Time Incident Frequency Rate ("LTIFR") was 0.06 compared to 0.08 from the same period last year. The Cerro Los Gatos operation finished Q1 without a reportable incident, a significant milestone in the operation's history.
