Production Report for the 3 months ended 31 March 2026

Performance in line with expectations and continued strong cash generation

Eduardo Landin, Chief Executive Officer commented:

"We have made a solid start to the year, with a strong operational performance at our flagship Inmaculada mine in Peru whilst the turnaround programme at Mara Rosa in Brazil is progressing well, with continued improvements in the plant and filtering operations. Overall, we have delivered another quarter of strong cash generation and we are on track to meet our full-year production and cost guidance. In parallel, we have continued to advance the engineering work at our Monte Do Carmo gold project in Brazil, where we are targeting the third quarter for project approval and the commencement of construction. Finally, the Environmental Impact Study for the Royropata silver project in Peru is progressing according to plan.

With Inmaculada performing well, an improved Mara Rosa, guidance maintained and an exciting portfolio of future growth projects, we see a strong future for Hochschild and look forward to updating the market on our progress"

Overview

In Q1 2026, Hochschild delivered attributable production of 75,599 gold equivalent ounces with an in-line performance from Inmaculada and a rising contribution from the Mara Rosa mine in Brazil partially offset by a slightly lower-than-expected contribution from San Jose mine in Argentina.

The Company reiterates its overall attributable production and all-in sustaining cost guidance for 2026 of 300,000-328,000 gold equivalent ounces and $2,157 and $2,320 per gold equivalent ounce, respectively.

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, Pallancata, Mara Rosa and 51% from San Jose.

Production

Inmaculada

Inmaculada's first-quarter production totalled 32,561 ounces of gold and 1.2 million ounces of silver, equivalent to 48,281 gold equivalent ounces (Q1 2025: 52,180 ounces). The mine delivered a solid quarter, with moderately higher tonnage partially offset by lower expected grades, reflecting higher prices and the resulting reduction in cut-off grades compared with Q1 2025. During the period, Inmaculada also made good progress on projects, including the completion and start-up of the reverse osmosis plant, as well as advancing the next lift of the tailings storage facility.

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

At San Jose in Argentina, tonnage was higher than in Q1 2025, while silver grades were slightly lower, consistent with the anticipated variability associated with mining in the vein border zones and the impact of higher prices on cut-off grades. Production totalled 0.7 million ounces of silver and 14,157 ounces of gold, equivalent to 26,991 gold equivalent ounces (Q1 2025: 23,630 ounces). Overall, the mine remains on track to achieve its annual target.

Mara Rosa

At Mara Rosa, the turnaround programme continued to deliver an improving operating performance, with greater plant stability, enhanced maintenance reliability and higher daily run rates. Peak performance during the quarter was 8.4kt in the crushing area, 6.9kt in milling and 7.0kt in the filter plant. The Company also progressed the mining contractor replacement, with mobilisation of the new contractor reaching 75% by the end of March. In parallel, the new tailings thickener continued to progress in line with schedule, with all major components on site and civil foundations and pre-assembly underway. Commissioning is expected to begin at the end of this month, with operations scheduled to start by the end of May 2026.

Overall, first-quarter production totalled 13,552 gold equivalent ounces (Q1 2025: 16,062 ounces) with output moderately below expectations, reflecting constrained equipment availability, weaker waste development and the resulting reduced access to higher-grade zones. These factors along with the rainy season impacted tonnage and grades.

Average realisable prices and sales

Average realisable precious metal prices in Q1 2026 (which are reported before the deduction of commercial discounts) were $4,471/ounce for gold and $89.8/ounce for silver (Q1 2025: $2,708/ounce for gold and $33.2/ounce for silver).

Advanced Project: Monte Do Carmo

Work on the Monte Do Carmo project continued in Q1, including progress on:

§ Detailed engineering and major equipment evaluation

§ Permitting and legal work

§ Water and environmental studies

§ Pre-stripping and waste movement strategy clarification with regulators

§ Geotechnical and geochemical studies 

§ Project team recruitment

§ Key procurement packages including power, camp, earthworks and pre-stripping

The Company continues to expect the project to be submitted to the Board for final approval in the third quarter of this year.

Brownfield exploration

The 2026 brownfield exploration programme has begun at all sites during the period. The first drill results will be reported in the Q2 production statement in July.

Financial position

Total cash and cash equivalents and short-term investments were approximately $412 million as at 31 March 2026, resulting in a net cash position of approximately $95 million, a material improvement from the net debt position of $23 million reported at the end of 2025, driven by strong cash generation from operations. The total cash and cash equivalents and short-term investments figure includes: $230 million held in Argentina[4], of which $84 million is invested in financial instruments to mitigate inflation and devaluation risks; and $35 million held in Tiernan Gold to support development of the Volcan project.
