(3) Waste guidance is 57 - 67 million tonnes when including the San Dionisio pit.

Alberto Lavandeira, CEO, commented:

"We are pleased to have achieved the higher end of our FY2025 production guidance range, in part due to plant throughput that set a new record for Atalaya. This performance provides a solid foundation as we enter FY2026.

Looking ahead for the Riotinto District, we are increasing mining rates at San Dionisio, advancing infill drilling programmes at the San Antonio and Masa Valverde deposits, and progressing engineering works associated with plant modifications that could unlock value from our polymetallic resources. In Galicia, we remain active in our engagement with the Xunta and continue to advance engineering at Proyecto Touro.

At the same time, the fundamentals for copper continue to strengthen, with prices setting new highs thanks to growing demand from emerging technologies, consistent supply challenges at major mines and strategic stockpiling of critical metals like copper. Against this backdrop, we are optimistic about the future and remain confident in Atalaya's positioning and outlook."

The Company will provide FY2026 operating cost and capital expenditure guidance when it reports its 2025 Annual Results.

Asset Portfolio Update

Proyecto Riotinto

In H2 2025, waste stripping activities at San Dionisio accelerated, with total material mined of 5.8 million tonnes in Q4 2025 and 12.4 million tonnes in FY2025. San Dionisio represents a key component of Atalaya's strategy to increase copper production by sourcing higher-grade material from deposits throughout the Riotinto District to be blended with ore from Cerro Colorado.

At San Antonio, the polymetallic deposit located immediately east of the Cerro Colorado pit, the infill and step-out drilling programme made further progress and will continue in 2026.

Atalaya continued to advance the front-end engineering design of processing plant modifications that would allow for the simultaneous treatment of polymetallic and copper ores at Riotinto.

E-LIX Phase I Plant

In Q4 2025, the E-LIX Phase I plant operated for intermittent periods and produced zinc precipitates from copper-zinc concentrates, although at a variable and reduced capacity due to the focus on optimising the process. All zinc precipitates produced have been sold.

An independent engineering firm has completed the review of the operating parameters and confirmed the potential added value of the process when treating complex polymetallic concentrates like those prevailing in the Iberian Pyrite Belt.

Based on the conclusions of the engineering report, Atalaya's goal during 2026 is to profitably extract zinc and precious metals from bulk copper-zinc concentrates produced at Proyecto Riotinto.

Atalaya continues working with Lain Technologies on the long term operating strategy, including existing funding requirements, to achieve a profitable application of E-LIX at its deposits in the Iberian Pyrite Belt.

Riotinto District - Proyecto Masa Valverde ("PMV")

During Q4 2025, infill and extensional drilling at the Masa Valverde deposit continued and further infill drilling is planned for 2026. Focus will remain on the stockwork-style mineralisation, which is expected to be amenable for processing at the existing Riotinto facilities, and support Atalaya's initial focus on the Masa Valverde copper zones. Development of the access ramp is anticipated to begin once the inminent purchase of certain surface rights is completed, subject to final Board approval.

PMV has been granted the two key permits required for development - the Unified Environmental Authorisation (or in Spanish, Autorización Ambiental Unificada ("AAU")) and the exploitation permit.

Proyecto Touro

On 24 June 2024, Atalaya announced that Proyecto Touro, via its local entity Cobre San Rafael, was declared a strategic industrial project by the Council of the Xunta de Galicia ("XdG"). Under legislation of the Autonomous Community of Galicia, the status of strategic industrial project (or in Spanish, Proyecto Industrial Estratégico ("PIE")) acts to simplify the administrative procedures associated with the development of industrial projects and intends to substantially reduce permitting timelines.

This declaration highlights the XdG's commitment to promoting new investment that will benefit the region and also support the objectives of the European Union. As a result, Cobre San Rafael has applied to the second call for strategic projects launched by the European Commission, where the main objective is to ensure a secure and sustainable supply of critical raw materials for European industry.

The XdG is continuing its review according to the simplified procedures afforded to projects with PIE status. The public information period, which serves to inform the surrounding communities and organisations about the proposed project, concluded on 31 January 2025. Cobre San Rafael has addressed the feedback from the public information period, and most sectoral reports from the Xunta de Galicia have been finalised, with only two reports still pending. The Company has also responded to requests for additional information and is awaiting a small number of corresponding replies.

The Company continues to engage with the many stakeholders in the region and is restoring the water quality of the rivers around Touro by operating its water treatment plant. The Company has also intensified its recruitment initiatives in relation to its potential future workforce.

Engineering, cost estimation and financial modelling works are advancing as expected. In addition, infill and step-out drilling programmes will continue in 2026.

Proyecto Ossa Morena

Drilling is expected to begin at the Guijarro-Chaparral gold-copper project in Q1 2026.

Proyecto Riotinto East

Drilling will begin at the Cerro Negro and Peñas Blancas permits in Q1 2026.

Skellefte Belt and Rockliden (Sweden)

In November 2024, Atalaya announced that it had entered into two binding agreements with Mineral Prospektering i Sverige AB ("MPS") pursuant to which Atalaya can earn an initial 75% interest in two separate land packages in Sweden. The Skellefte Belt land package ("Skellefte Belt Project") and the Rockliden land package ("Rockliden Project") are located in two notable districts that host many large-scale volcanogenic massive sulphide ("VMS") deposits and mines owned by Boliden AB. Both regions are underexplored and could increase Atalaya's exposure to critical minerals in Europe.

Atalaya and MPS have concluded their autumn drilling campaign, which finished in late November with 11 holes totalling over 3,200 meters. Results confirm a significant extension of mineralisation at the Bjurträskgruvan area, with complete laboratory assays expected soon.

The winter drill programme is now underway at both the Skellefte Belt and Rockliden projects, with three drill rigs currently active. Drilling at previously defined targets commenced during the second week of January, supported by ongoing Fixed-Loop Electromagnetic (FLEM) ground surveys and advanced modelling to refine target definition.

In parallel, work plans and authorisations for new targets identified by the summer airborne (VTEM) survey are well advanced. Ground-based exploration, including FLEM surveys and drilling on these targets, is scheduled to begin in the coming months.

Corporate Activities Update

On 30 December 2025, the Company announced that it intends to appoint Dr. Michael ("Mike") Graham Armitage as an independent non-executive director with effect from 19 January 2026. Mike will replace Steve Scott who stepped down from the Board on 31 December 2025.

As a result, several changes will be made in relation to the composition of the Board's various committees effective 19 January 2026.
