Production Report for the 12 months ended 31 December 2025

Production in line with guidance

Eduardo Landin, Chief Executive Officer commented:

"Production in 2025 was in line with our revised guidance, driven by a strong operational performance at Inmaculada and San Jose. Mara Rosa delivered significant progress in the period and is performing as expected. We continue to make encouraging progress in our brownfield exploration programme and, in keeping with our strategy of unlocking value from non-core assets, in Q4 we also completed the listing of Tiernan Gold which bolstered financing for the Volcan gold project.

The current unprecedented commodity price rises are providing a strong financial tailwind for the business, and whilst there has been also an immediate impact on royalties, profit sharing, and selling expenses, we continue to focus on cost discipline in order to underpin higher margins. We are confident of delivering further operational and strategic progress this year, and our 2026 guidance reflects rising output from Mara Rosa alongside solid contributions from Inmaculada and San Jose, while our preparatory work at Monte do Carmo remains on track and a final investment decision will be made later this year."

Overview

In Q4 2025, Hochschild Mining PLC (HOC.LN) (OTCMKTS: $HCHDF) ("Hochschild" or "the Company") delivered attributable production of 79,605 gold equivalent ounces or 6.6 million silver equivalent ounces, 13% higher than Q3 due to solid quarterly contributions from Inmaculada and San Jose and the continued ramp-up at Mara Rosa, driven by improved mining configuration and performance, and higher plant availability through enhanced maintenance reliability. Overall, 2025 attributable production was 311,509 gold equivalent ounces or 25.9 million silver equivalent ounces.

The Company expects its all-in sustaining cost for 2025 to be at the higher end or marginally above revised guidance of between $1,980 and $2,080 per gold equivalent ounce.

TOTAL GROUP PRODUCTION

Total production includes 100% of all production, including production attributable to Hochschild's joint venture partner at San Jose.

ATTRIBUTABLE GROUP PRODUCTION

Attributable production includes 100% of all production from Inmaculada, Mara Rosa and 51% from San Jose.

Production

Inmaculada

Fourth quarter production at Inmaculada was 37,857 ounces of gold and 1.33 million ounces of silver, which amounts to an attributable gold equivalent output of 53,833 ounces. Performance improved versus Q3 2025, reflecting stronger gold grades and recoveries following the temporary grade reduction associated with mine sequencing adjustments in the prior quarter. The Company is focused on managing grade variability inherent to sequencing, maintaining access to higher-grade zones, and sustaining stope inventory through continued geomechanical discipline and flexibility in development work.

For the full year, Inmaculada delivered 142,233 ounces of gold and 5.6 million ounces of silver which makes 209,921 attributable gold equivalent ounces.

San Jose (the Company has a 51% interest in San Jose)

The San Jose mine delivered a solid Q4 performance, producing 1.0 million ounces of silver and 24,485 ounces of gold which amounts to 36,639 gold equivalent ounces. This represents a 17% increase versus Q3 2025, driven by a stronger gold grade profile and steady plant performance. Operational execution remained consistent with stable throughput and improved grades. The Company remains focused on managing dilution and grade when mining the border zones, as well as maintaining disciplined mine plan execution and stope selection.

For the full year, the mine delivered 76,970 ounces of gold and 3.6 million ounces of silver which is 120,639 attributable gold equivalent ounces with increased tonnage from the expansion of the plant capacity offset by the scheduled grade reductions.

Mara Rosa

At Mara Rosa, the operational ramp-up continued through Q4, supported by pushback development that improved access to higher-grade zones and by stabilising the processing plant through stronger maintenance routines. This resulted in increased throughput, improved operational stability and boosted ore exposure and productivity. Key focus areas included rainy-season water management and strengthening filtration and detox availability through better maintenance, spares readiness, and moisture control. Mining performance was boosted by reliable equipment availability and infrastructure reliability.

With the ramp-up progressing in line with expectations, the Company is currently managing the rainy season, completing the installation of the new tailings thickener and securing sustained filtration and detox availability. Management remains focused on maintaining consistent performance through reliable mining and plant operations as well as workforce stability.

Fourth-quarter production totalled 7,067 ounces of gold, plus minor silver by-product, which amounts to 7,086 gold equivalent ounces, a strong improvement on the third quarter when output remained constrained due to the actions taken as part of the previously-announced turnaround strategy which included a temporary plant stoppage. For the full year, Mara Rosa delivered 40,062 gold equivalent ounces.

Average realisable prices and sales

Average realisable precious metal prices in Q4 2025 (which are reported before the deduction of commercial discounts) were $3,959/ounce for gold and $65.3/ounce for silver (Q4 2024: $2,464/ounce for gold and $30.7/ounce for silver).

For 2025 as a whole, average realisable precious metal prices were $3,222/ounce for gold and $44.2/ounce for silver (2024: $2,345/ounce for gold and $28.7/ounce for silver).

Brownfield exploration

Inmaculada

In Q4 2025, the Company performed just over 10,000m of resource drilling in the Angela Tesoro, Dayana, Isabella, Lady, Martha, Split NS, Lu and Lirio structures as well as just over 4,750m of potential drilling Melisa and Melisa NE veins with the key results below:

In the first quarter of 2026, the team is planning 3,600m of potential drilling in Inmaculada Central and Southern zones.

Royropata

Exploration work continued at the Royropata project in the fourth quarter with the team expected to add substantial resources from the overall 2025 programme. This is expected to be reported at the Full Year Results.

San Jose

At San Jose, the brownfield team carried out 3,819m of potential drilling in the Angelica, Piso Pilar, Pilar, HVS, HVC and Escondida EW veins in the area surrounding the mine as well as 4,450m in machine learning targets.

The plan for the first quarter is to perform potential drilling in the HV-W area and in the northern zone.

Mara Rosa

At Mara Rosa, the brownfield team carried out 2,244m of potential drilling in the Morro Redondo and Araras-Speti areas and 3,320m of potential drilling in the Posse-Passo and Araras structures.

The plan for the first quarter is to continue the potential drilling in the Passo-Araras-Speti areas and structures parallel to Posse.

Monte Do Carmo

During Q4, a total of 1,451m of potential drilling was completed in the Boqueirao and Agua Suja targets in addition to 3,013m of resource drilling in Sierra Alta, yielding economic results.

During Q1 2026, resource drilling will continue in Sierra Alta.

Financial position

Total cash was approximately $317 million as at 31 December 2025, resulting in net debt of approximately $23 million. The substantial improvement in the financial position is a result of a strong operational quarter at Inmaculada and San Jose, rising metal prices and the completion of the Tiernan Gold transaction. Such increases in prices are boosting cash generation but are also impacting cost inflation due to the immediate impact on workers profit sharing, royalties, commercial discounts and selling expenses in Argentina.

2026 Guidance

The overall attributable production target for the year is 300,000-328,000 gold equivalent ounces.[4]

2026 production split

The all-in sustaining cost from operations in 2026 is expected to be between $2,157 and $2,320 per gold equivalent ounce.

2026 AISC split

The capital expenditure budget for 2026 is approximately $210-225 million allocated to sustaining and development expenditure. The project capital expenditure budget for Royropata is set at $11 million. The budget allocated to the brownfield exploration programme for 2026 is $45 million.
