Arturo Préstamo, Executive Chairman and CEO of Santacruz, commented: “Q1 2025 represents a strong beginning to the year, reflecting our continued emphasis on operational efficiency and financial discipline. We achieved a notable year-over-year improvement in profitability and cash generation, with gross profit, and adjusted EBITDA all registering substantial growth. These results underscore the strength, flexibility, and scalability of Santacruz’s business model. We remain firmly focused on driving long-term value through disciplined capital allocation and a commitment to safety and operational excellence.”

Mr. Préstamo continued, “We maintained a strong liquidity position at quarter-end, closing with $33 million in cash and cash equivalents. This was achieved despite a $10 million payment under the voluntary acceleration plan and the settlement of more than $19 million of 2024 current income tax. These outcomes reflect the strength of our underlying cash flows and our prudent approach to financial management, which continue to support our strategic priorities as we strengthen our balance sheet integrity. Backed by a seasoned team in Mexico, Bolivia, and Canada, along with a flexible and efficient operating model and a strong track record of execution, we are well-positioned to take advantage of today´s metal prices and keep delivering sustainable, long-term value for our shareholders.”

Selected consolidated financial and operating information for Q1 2025 and Q1 2024 and Q4 2024 are presented below. All financial information is prepared in accordance with International Financial Reporting Standards (“IFRS”), and all dollar amounts are expressed in thousands of US dollars, except per unit amounts, unless otherwise noted.

Production

In Q1 2025, the Company processed 471,773 tonnes of ore, producing 3,688,129 silver equivalent ounces. This total includes 1,590,063 ounces of silver and 20,719 tonnes of zinc.

Q1 2025 vs Q4 2024

In Q1 2025, ore processed was slightly lower than in Q4 2024, reflecting the typical seasonal slowdown, particularly across Bolivian operations, as well as scheduled mine sequencing and temporary constraints that modestly impacted throughput. Notably, Zimapán had a 3% increase in processed mineralized material, supported by sustained operational efficiency and continuous optimization efforts. Silver equivalent production was 10% lower, primarily due to reduced head grades and throughput. Silver output declined by 10%, while zinc production was 11% lower, consistent with the expected mine plan for the quarter. Despite these lower volumes, the Company remained focused on maximizing margins by prioritizing higher-silver-content zones. With temporary constraints now resolved and silver prices trending favorably, operations are well-positioned to deliver strong cash flow generation throughout the year.

Q1 2025 vs Q1 2024

In Q1 2025, consolidated operational performance remained stable year-over-year, with total tonnes processed virtually unchanged compared to Q1 2024. Silver equivalent production was 5% lower, reflecting the impact of temporary operational constraints and expected ore body variability at certain Bolivian operations. Despite these factors, silver output remained flat, supported by higher silver head grades at key operations and improved metallurgical recoveries, particularly at the Caballo Blanco Group. Zinc production decreased by 9%, primarily due to lower throughput and head grades at Porco and Caballo Blanco, partially offset by strong results at Zimapán, where zinc output rose 23% year-over-year. Zimapán also led overall growth, increasing material processed by 9% and silver equivalent production by 14%, highlighting its operational improvements, as we develop and prepare level 960 now with all required underground equipment at site. The strategic reorganization of the Caballo Blanco and San Lucas, particularly the reallocation of Reserva mine’s output, also contributed to improved metallurgical efficiency and stable margins. These results highlight the flexibility provided by the Company’s diversified asset base and its focus on maximizing recoveries.

Cash Cost and All-in Sustaining Cost per Silver Equivalent Ounce Sold

Starting January 1, 2025, Bolivian operations adopted a new exchange rate methodology supported by IAS 21, replacing the fixed official rate (6.96 BOB/USD) with a market-based spot rate (average 12.20 BOB/USD) obtained from banks. Under IAS 21, entities should estimate a spot rate at which an orderly exchange transaction would take place between market participants under prevailing economic conditions. Recording BOB denominated transactions in USD using the market-based rate, provides a more accurate representation of the economic reality of the underlying transactions.

Q1 2025 vs Q4 2024

Costs improved notably in Q1 2025 when compared to Q4 2024, with consolidated cash cost and AISC per silver equivalent ounce sold decreasing to $17.84 and $22.34, respectively, from $22.38 and $27.83. This improvement was mainly driven by the Bolivian operations (Bolívar, Porco, Caballo Blanco, and San Lucas) which reported significant reductions across all cost metrics. Caballo Blanco Group saw the most considerable improvements. In contrast, Zimapan’s AISC increased from $27.13 to $34.32/oz, as a significant portion of its annual capital budget was deployed during Q1 to accelerate key investments aimed at increasing future production at Carrizal mine level 960.

Q1 2025 vs Q1 2024

Compared to Q1 2024, there were substantial cost improvements during Q1 2025. Consolidated cash cost decreased from $21.19 to $17.84/oz, and AISC from $24.27 to $22.34/oz. The most notable improvements came from Caballo Blanco, where AISC dropped significantly due to better metallurgical performance as a consequence of achieving improvements and efficiencies at underground and milling operations. Zimapán, however, recorded an increase in AISC to $34.32/oz (from $22.59), as a substantial portion of its budgeted CAPEX was executed in Q1 to bring forward investments that support higher production in upcoming quarters at Carrizal mine at level 960.
