Alberto Lavandeira, CEO, commented:
"Production for the third quarter was consistent with our full-year outlook and benefitted from strong plant availability. Cost performance is trending favourably compared to our guidance ranges, and combined with strong copper prices, our balance sheet continues to strengthen.
We remain busy across our project pipeline in the Riotinto District, including stripping at San Dionisio, infill drilling at San Antonio and Proyecto Masa Valverde and engineering works for the future polymetallic circuit.
At Proyecto Touro, our team is active on many fronts, including engaging with the Xunta de Galicia in relation to the environmental impact review, progressing detailed engineering and also completing exploration drilling.
We are increasingly optimisitic about Atalaya's growth strategy, thanks to a portfolio of projects that have the potential to deliver new production into a copper market that is becoming increasingly supply constrained."

Asset Portfolio Update
Proyecto Riotinto
In May 2025, San Dionisio was granted the Unified Environmental Authorisation (or in Spanish, Autorización Ambiental Unificada ("AAU")) by the Junta de Andalucía ("JdA"), which allows for the expansion of mining activities. During Q3 2025, waste stripping activities at San Dionisio accelerated, with total material mined of 4.2 million tonnes. 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, eight drill holes were completed during the quarter as part of the ongoing infill and step-out drilling programme.
Atalaya is also advancing the front-end engineering design of a new processing circuit that would allow for the simultaneous treatment of polymetallic and copper ores at Riotinto.
E-LIX Phase I Plant
In Q3 2025, the E-LIX Phase I plant demonstrated continuous operations over extended periods, producing zinc precipitates from copper-zinc concentrates, although at a reduced capacity.
Lain Technologies also continues to focus on optimisation and debottlenecking initiatives. In conjunction, an independent third-party engineering firm initiated a review to assess actual and potential plant performance, confirm achievable throughput capacity and identify further optimisation opportunities. Once the third-party review has been completed, Atalaya and Lain Technologies will determine a future operating strategy for the E-LIX Phase I plant.
Riotinto District - Proyecto Masa Valverde ("PMV")
On 10 July 2025, the Company announced results from its ongoing drilling programme at PMV. Two rigs remain active and are focused on infill and extensional drilling at the Masa Valverde deposit. In addition, two geotechnical holes were recently completed.
Recent drilling results are primarily associated with 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 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. In this context, Cobre San Rafael will apply 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.
Finally, infill and step-out drilling programmes continue, with the objective of determining the limits of mineral orebodies both at depth and laterally.
Proyecto Ossa Morena
Three drill holes were recently completed at the Alconchel-Pallares copper-gold project.
Proyecto Riotinto East
Following the completion of the gravimetric survey and soil geochemistry, an area with several coincident gravity-geochemical targets has been outlined at Cerro Negro and Peñas Blancas. Drilling is expected to commence at Cerro Negro during the next quarter.
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.
The VTEM airborne electromagnetic survey carried out this summer over the Skellefte Belt project has extended high-resolution coverage throughout the permit area. This work has identified multiple new anomalies that are currently being systematically ranked and modelled. Following further refinement with ground electromagnetic (FLEM) surveys where required, these targets will be incorporated into the upcoming winter drilling programme.
Following the processing and modelling of several VTEM anomalies, which were further refined through FLEM and detailed UAV magnetic surveys conducted over the summer, a drill rig was mobilised and began drilling activities in the final days of September.
Recent drilling and ground geophysical surveys (including Borehole BHEM and FLEM) have indicated extensions of mineralisation at both the Bjurtraskgruvan deposit (Skellefte Belt Project) and the Rockliden Project. These identified areas will undergo drill testing during the upcoming winter months, and planning for these activities is currently underway.
Corporate Activities Update
As announced on 17 September 2025, alternative arrangements were implemented to assist the holders of Atalaya ordinary shares represented by physical certificates as at 9 January 2025 to convert their shares into electronic form represented by CREST Depositary Interests.
