Alberto Lavandeira, CEO, commented:

"The publication of our second annual sustainability report builds on the company-wide efforts we have made in recent years to enhance our corporate disclosure. Atalaya has always operated in a safe and responsible manner, with a focus on positively impacting our nearby communities, the environment and our many other stakeholders.

We continue to collaborate with local municipalities via the Fundación Atalaya Riotinto, which supports and sponsors initiatives related to education, health, the environment and culture.

We have made investments in projects that reduce our external water consumption and initiated construction of our 50 MW solar plant for self-consumption, which will lower our GHG emissions. We are also studying further renewable energy options, such as the installation of wind turbines at Riotinto.

In terms of governance, we appointed a board member with significant expertise in ESG matters, established a Sustainability Committee and updated our code of ethics to include an express commitment to human rights, and we continue to make progress in the implementation of our compliance system.

During 2023, we will make further progress and should like to thank all our stakeholders for their ongoing support."
