FIRST QUARTER PRODUCTION REPORT

FOR THE THREE MONTHS ENDED 31 MARCH 2025

Octavio Alvídrez, Chief Executive Officer, said:

"We have started 2025 in line with our expectations, delivering a stable operating performance and maintaining the momentum we achieved in 2024. Our full year guidance remains unchanged. Silver production is down as anticipated, as we account for the impact of cessation of mining activities at the San Julián DOB, although we expect to see a stronger second half performance. Gold production is up on the same period last year, driven by a continued strong performance at Herradura, as well as the benefit of processing gold inventories accumulated in the previous period. With those inventories now depleted, we expect gold production to normalise in line with our guidance.

Overall, our operations remain well-aligned with our plan, positioning us well to capitalise on stronger precious metals prices. Cost discipline remains a key focus, supported by a favourable Mexican peso USD exchange rate. We are focused on sustaining our operational stability, maintaining our strong financial performance and delivering value to our stakeholders throughout 2025, with our core priority as always being the safety of our people and the well-being of our communities."

HIGHLIGHTS

Silver

·    Quarterly attributable silver production of 12.4 moz (including Silverstream) was down 9.7% vs. 4Q24 primarily due to lower ore grade and volume of ore processed at Saucito, the cessation of mining activities at San Julián DOB and lower volume of ore processed at San Julián Veins. This was partly mitigated by the higher ore grade at Fresnillo.

·    Quarterly attributable silver production (including Silverstream) decreased 8.4% vs. 1Q24, mainly due to the cessation of mining activities at San Julián DOB and a decreased ore grade and volume of ore processed at Ciénega, partly mitigated by the higher production from the Silverstream and increased ore grade at Fresnillo.

Gold

·    Quarterly attributable gold production of 156.1 koz, down 23.5% vs. 4Q24, primarily due to the decrease in volumes of ore processed and lower ore grade at Herradura, Saucito, Fresnillo and Ciénega, and a lower contribution from Noche Buena.

·    Quarterly attributable gold production increased 10.8% vs. 1Q24 primarily due to the higher ore grade, increased volume of ore processed and recovery rates at Herradura, offset by the lower ore grade at Saucito and lower ore grade and volume of ore processed at Ciénega.

By-Products

•     Quarterly attributable by-product lead production decreased 10.9% vs. 4Q24 due to the lower ore grade and volume of ore processed at Fresnillo and Ciénega and the cessation of operations at San Julián DOB partly mitigated by the higher ore grade at Juanicipio.

•     Quarterly attributable by-product zinc production decreased 12.8% vs. 4Q24 mainly due to the lower ore grade and volume of ore processed at Fresnillo, the cessation of operations at San Julián DOB and lower ore grade, volume of ore processed and recovery rate at Ciénega, partly mitigated by higher ore grade at Juanicipio and Saucito.

•     Quarterly attributable by-product lead production remained flat when compared to 1Q24 due to the higher ore grade at Saucito, offset by the decreased contribution from San Julián DOB.

•     Quarterly attributable by-product zinc production decreased vs. 1Q24 primarily due to the lower contribution from San Julián DOB and lower volume of ore processed at Fresnillo, partly mitigated by the higher ore grade at Saucito.

SAFETY PERFORMANCE

We remain committed to instilling a true culture of safety across our business and to meeting our Zero Fatalities target. We continue to work to identify preventive measures, focusing on training and maintaining stringent adherence to our safety policies to provide a safer environment for our workforce.

MINING OPERATIONS

FRESNILLO MINE PRODUCTION

Quarterly silver production increased 14.2% vs. 4Q24 driven by the higher ore grade and decreased dilution following the optimisation of the development of narrower veins. These factors offset the lower volume of ore processed due to the lower availability of ore at the flotation plant while the operation of the deepened San Carlos shaft was optimised following its commissioning in 4Q24. This process has been concluded and volumes of ore processed are expected to increase in the coming months.

Mine development rates decreased to an average of 2,916m per month in 1Q25 (3,424m per month in 4Q24) due to lower equipment availability. Maintenance and repair to the equipment has been carried out and development rates are expected to increase in the second quarter.  

Quarterly silver production remained at similar levels when compared to the 1Q24 as the higher ore grade compensated for the lower volume of ore processed.

Quarterly gold production decreased 23.2% vs 4Q24 mainly due to lower ore grade and volume of ore processed as previously mentioned.

Quarterly gold production increased 8.5% vs. 1Q24 driven by the higher ore grade, partly mitigated by the decreased volume of ore processed.

The silver ore grade in 2025 is expected to be in the range of 160 to 180 g/t, while the gold ore grade is estimated to be between 0.60 to 0.70 g/t.

SAUCITO MINE PRODUCTION

Quarterly silver production decreased 19.7% vs. 4Q24 due to increased dilution and a lower ore grade compared to the higher ore grades from long hole drilling in the Alamito and Roble areas in 4Q24. The lower volume of ore processed driven by the decreased availability of contractors' bolting equipment and the lower volume extracted from the Central, Natalias and Mezquite areas further impacted silver production. This equipment is being replaced and additional training is being given with the objective of increasing the availability and productivity of this equipment in the second quarter.

Quarterly silver production was in line with 1Q24 as the lower volume of ore processed driven by the previously mentioned factors was partially compensated for by the slightly higher ore grade from the cut and fill western areas.

Quarterly gold production decreased vs. 4Q24 and 1Q24 due to the lower ore grade and decrease in volume of ore processed.

Mine development rates decreased to 2,392m per month in 1Q25 (4Q24: 2,527m per month) primarily due to the decreased availability of contractors' bolting equipment as mentioned above.

The silver ore grade for 2025 is expected to be in the range of 200-220 g/t, while the gold grade is estimated to be between 0.90-1.10 g/t.

PYRITES PLANT

*Includes concentrates of Fe from Saucito and Fresnillo.

JUANICIPIO - ATTRIBUTABLE

Attributable quarterly silver production increased 5.0% vs. 4Q24 mainly driven by the higher ore grade due to increased dilution control and the higher volume of ore processed.

Attributable quarterly silver production was in line vs. 1Q24 as improved recovery rates and the higher volume of ore processed given the optimisation of the maintenance programme compensated for the lower ore grade.

Attributable gold production increased 12.8% vs. 4Q24 due to the higher ore grade, improved recovery rate and the increase in volume of ore processed as mentioned above.

Attributable gold production increased 2.7% vs. 1Q24 mainly due to a higher recovery rate and the increased volume of ore processed which more than compensated for the lower ore grade.

The silver ore grade in 2025 is expected to be in the range of 380-430 g/t, while the gold grade is estimated to be between 1.2-1.4 g/t.

CIÉNEGA MINE PRODUCTION

Quarterly gold production decreased 17.5% vs. 4Q24 and 23.8% vs. 1Q24 due to the decrease in volume of ore processed given the lower availability of bolting equipment, causing some delays in production although it is expected to be recovered during the second half of the year. Additionally, less ore extracted from high ore grade areas such as Jessica Transversal and Vetas Angostas, as well as higher dilution at the Taspana area, which is approaching the end of its operation, contributed to the lower gold production. Recovery plans in place and higher grade zones expected in Q3 and Q4 maintain expected production in 2025 aligned with the plan.

Quarterly silver production decreased 14.1% vs. 4Q24 mainly due to the lower volume of ore processed.

Quarterly silver production decreased 26.0% vs. 1Q24 given the lower ore grade and volume of ore processed.

The gold and silver ore grades for 2025 are estimated to be in the ranges of 1.1-1.3 g/t and 130-150 g/t respectively.

SAN JULIÁN MINE PRODUCTION

SAN JULIÁN VEINS

Quarterly silver production decreased 13.5% vs. 4Q24 mainly due to the lower volume of ore processed driven by an electrical fault that affected the ball mill and required an unplanned maintenance stoppage in February.

Quarterly gold production decreased 9.7% vs. 4Q24 due to lower volume of ore processed partially mitigated by the higher ore grade. Quarterly gold production was in line with 1Q24.

Silver and gold ore grades in 2025 are expected to be in the ranges of 210-230 g/t and 1.10-1.30 g/t respectively.

SAN JULIÁN DISSEMINATED ORE BODY (DOB)

Mining activities concluded in November 2024 as per previous guidance.

HERRADURA TOTAL MINE PRODUCTION

Quarterly gold production decreased 21.9% vs. 4Q24 mainly due to the decrease in volume of ore processed and lower ore grade following an extraordinary performance in 4Q24, in line with the production plan.

Quarterly gold production increased 29.9% vs. 1Q24 as a result of higher ore grade from planned areas and additional gold inventories processed in 1Q25, whereas mining activities in 1Q24 were disrupted by heavy rain.

The average gold ore grade in 2025 is expected to be in the range of 0.50-0.70 g/t.

NOCHE BUENA

3,624 ounces of gold were recovered from the leaching pads at Noche Buena in 1Q25, a 33.0% decrease when compared to 4Q24 and 12.5% when compared to 1Q24. As previously announced, mining activities concluded in May 2023, and the closure mine plan continues as expected.

SILVERSTREAM

Quarterly silverstream production was line with the 4Q24 mainly due to higher ore grade and improved recovery rate, which compensated for the lower volume of ore processed.  

Quarterly silverstream production increased 22.9% vs. 1Q24 due to a higher volume of ore processed, partly offset by the lower recovery rate. 

We continue to evaluate the operational and financial situation at the Sabinas mine, as outlined with our FY24 results and we will update the market with any further detail in due course.
