Luca's CEO, Dan Barnholden commented "2025 was a transformational year for Luca Mining. We delivered strong operational growth, significantly increased production across both mines, improved our performance, including strong free cash flow, all while strengthening our balance sheet and advancing our long-term exploration and development programs. With production exceeding revised guidance across all five metals, revenues more than doubling, and adjusted EBITDA increasing 226%, we enter 2026 well positioned to continue executing on our growth strategy and delivering sustainable value for shareholders"

Despite strong operating performance, the Company reported a net loss of $21.1 million for the year. This result was driven by non-cash and non-operating items, primarily the negative change in the non-cash fair value of derivative liabilities of $38.9 million associated with the silver stream, non-cash accounting adjustments under IFRS and foreign exchange impacts.

Excluding these factors, underlying operating performance improved significantly year-over-year, as reflected in strong growth in Adjusted EBITDA, Net Free Cashflow before working capital items and mine operating cash flow.

Operational Performance

The Company achieved a step-change in operational scale in 2025, driven by increased throughput and improved operating stability across both Campo Morado and Tahuehueto.

Higher production volumes more than offset the impact of lower precious metal grades and modestly lower recoveries, demonstrating the strong operating leverage of the Company's assets. During the second half of the year, Luca significantly increased underground development and exploration activity to improve mine sequencing and access higher-grade zones, positioning the operations for improved performance going forward. 

Campo Morado (Guerrero, Mexico)

Campo Morado delivered strong operating performance in both the fourth quarter and full year 2025, reflecting increased throughput, improved plant stability, and continued progress on operational optimization initiatives.

In the fourth quarter, the mine processed 170,238 tonnes of mineralized material, representing a 21% increase over the same period in 2024. This resulted in strong production across key metals, including 9.2 million pounds of zinc (+75%), 1.3 million pounds of lead (+65%), and 277,789 ounces of silver (+61%), alongside 2.1 million pounds of copper (+5%) and gold production totaling 2,103 ounces (+5%). Total zinc equivalent pounds produced increased 59% to 30.9 million pounds from 19.5 million pounds in Q4 2024.

Cash costs averaged $1.08 per payable ZnEq pound (+11%), primarily reflecting higher treatment and refining charges, greater site support and indirect costs as the operation scaled up. All-in sustaining costs averaged $1.33 per ZnEq pound (+6%), primarily driven by increased sustaining capital expenditures, including underground development and the expansion of exploration programs. These investments are expected to support improved mine sequencing and access to higher-grade zones in future periods.

For the full year, Campo Morado contributed to consolidated throughput of over 700,152 tonnes milled (+38%), supporting significant increases in production across base metals. Zinc production reached 38.7 million pounds (+77%), lead 4.9 million pounds (+52%), and copper 9.0 million pounds (+31%), while silver production totaled 1.0 million ounces (+56%) and gold totalled 8,735 ounces (+29%). 

On an annual basis, cash costs decreased to $0.99 per zinc equivalent pound (-9%) reflecting the benefits of increased production volumes. Sustaining capital expenditures increased significantly to support accelerated underground development and exploration programs, which are expected to improve mine sequencing, operational flexibility, and access to higher-grade zones in future periods. All-in Sustaining Costs per pound remained consistent at $1.24 per zinc equivalent pound as the increased sustaining capital spend was offset by higher production levels.

Operational initiatives focused on improving blending control, reagent optimization, and circuit stability continued to enhance metallurgical performance and concentrate quality. Improved ore blending practices and process control adjustments contributed to more consistent recoveries during the second half of the year.

Underground development advanced new mining areas and improved access to additional stopes, supporting both near-term production stability and longer-term operational flexibility. Exploration drilling during the year also returned encouraging results adjacent to existing workings, reinforcing the potential for near-mine resource expansion and future production growth.

Tahuehueto (Durango, Mexico)

Tahuehueto delivered a transformative year in 2025, achieving commercial production on March 31, 2025, and continued to increase operating scale through the year, contributing significantly to the Company's overall growth in production and financial performance.

In the fourth quarter, the mine processed approximately 90,737 tonnes (+34%) of ore as throughput continued to ramp up with improving plant availability. Gold production of 4,285 ounces (-16%) was impacted by lower grades during the period as mining progressed through development areas, while silver production of 106,256 ounces remained strong, benefiting from increased grades, throughput and improved plant stability. Overall gold equivalent production decreased 5% to 6,929 ounces in Q4 2025.

Cash costs per AuEq ounce sold averaged $2,197 (+67%), reflecting the lower ounces produced. All-in sustaining costs increased to $3,201 in the quarter (+110%), driven by lower gold grades, continued mine development, and increased exploration expenditures as the operation advances toward steady-state performance.

For the full year, Tahuehueto processed 311,629 tonnes compared to 165,470 in 2024, with gold production contributing 17,410 ounces (+39%), alongside strong silver production growth of 316,166 ounces (+137%), reflecting a full year of ramp-up and increasing operational stability. Total gold equivalent ounces produced for the year increased to 26,200 (+42%).

On an annual basis, cash cost per AuEq ounce sold was $2,176 versus $1,560, and AISC per AuEq ounce sold was $2,832 versus $1,845. The year-over-year increase in AISC reflected higher sustaining and ramp-up-related expenditures as the Company invested in underground development, plant improvements and mine infrastructure to support long-term operating stability.

During the year, the Company advanced installation of a copper-lead separation circuit, with mechanical installation substantially completed in the fourth quarter. This system is expected to improve recoveries, concentrate quality, and payabilities by enabling the production of separate copper and lead concentrates. Commissioning is expected in 2026.

Underground development accelerated during the second half of the year, improving mine sequencing and operational flexibility, while exploration drilling continued to return encouraging results from near-mine targets.
