Q1 2025 Production Report.

             _____________________________________________________________________________________

23 April 2025

Production Report for the 3 months ended 31 March 2025

Eduardo Landin, Chief Executive Officer commented:

"Traditionally, the first quarter represents our lowest production period and 2025 has been in line with this. Pleasingly, Inmaculada has delivered a solid performance and we are seeing encouraging developments in Argentina, where the easing of exchange controls and the resulting currency weakness are expected to improve San Jose's cost position in the long-term. 

However, at the Mara Rosa operation in Brazil, performance has been temporarily impacted by adverse weather conditions, with heavier-than-usual seasonal rains continuing into April, along with carry-over delays in waste removal from the previous year. Additionally, we have encountered operational challenges related to our mining contractor, in an environment of increasing pressure on the availability of skilled labour, partly driven by elevated metal prices. In response, we have implemented a series of measures including the expansion of our waste removal fleet and, during the second quarter, we will accelerate waste removal. Production in Q2 is expected to remain broadly in line with Q1 but we remain confident in a recovery in production during the second half of the year and reaffirm our full-year production guidance"

Overview

In Q1 2025, Hochschild delivered attributable production of 79,941 gold equivalent ounces with an in-line performance from Inmaculada offset by a lower-than-expected contribution from the Mara Rosa mine in Brazil.

The Company reiterates its overall attributable production and all-in sustaining cost guidance for 2025 of 350,000-378,000 gold equivalent ounces and $1,587 and $1,687 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 was 34,780 ounces of gold and 1.4 million ounces of silver which amounts to gold equivalent output of 52,180 ounces (Q1 2024: 57,877 ounces). Slightly higher than expected tonnage in the quarter was offset by lower gold grades although the overall result for the period was in line with the 2025 plan and puts the mine on track to achieve its annual target.

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

The first quarter at San Jose in Argentina is traditionally a shorter operational period due to the scheduled hourly workers' holiday which was taken during February this year. Moderately higher-than-expected tonnage in the period was offset by lower gold grades. Production was 0.7 million ounces of silver and 14,157 ounces of gold, which makes 22,946 gold equivalent ounces with the mine remaining on track to achieve its annual target.

Mara Rosa

In Brazil, production for the first quarter of the year was scheduled to be lower due to the annual rainy season. However, from December 2024, heavier-than-expected rainfall has impacted the ability to access ore and, in particular, the higher-grade zones within the pit. The weather conditions also contributed to delays in waste removal. In addition, the mine has also experienced continued performance issues with the mining contractor as well as increased turnover in personnel due to higher metal prices. Production in the period was 16,059 ounces of gold.

Management has initiated a programme to increase throughput, including expanding the scale of mining operations and strengthening the drilling and blasting processes. This also includes the expansion of our waste removal fleet, at no additional cost, doubling capacity from 1.5 million tonnes to 3.0 million tonnes per month, supported by the addition of six CAT 777 trucks and a Hitachi 2600 excavator to recover from the accumulated delays from the last two quarters. Production is expected to improve in the second half of the year after a similar level of production in the second quarter which will be a period of stabilisation.

Average realisable prices and sales

Average realisable precious metal prices in Q1 2025 (which are reported before the deduction of commercial discounts) were $2,708/ounce for gold and $33.2/ounce for silver (Q1 2024: $2,106/ounce for gold and $23.6/ounce for silver).

Advanced Project: Monte Do Carmo

Work has continued on the Monte Do Carmo project in the first quarter and included:

§ Completion of metallurgical testwork

§ Progress on detailed engineering reaching 19% completion

§ Meetings with the Governor of the state of Tocantins

§ Meeting with Tocantins state agency to discuss workforce development plans

§ Award of the installation licence

§ Signing of contract for transmission line as well a power distribution network to support water intake and construction infrastructure

Brownfield exploration

The 2025 brownfield exploration programme has begun at all sites during the period with early result pending. The first drill results will be reported in the Q2 production statement in July.

Financial position

Total cash was approximately $83 million as at 31 March 2025 resulting in a net debt position of approximately $248 million. Net debt in Q1 was impacted by a temporary higher level of payments associated to agreements with communities, performance bonuses and taxes.
