Central Asia Metals PLC (AIM: CAML) is pleased to announce the publication of its 2025 Sustainability Report, detailing the Group's sustainability strategy and performance for the year ended 31 December 2025, including at the Kounrad copper operation in Kazakhstan and the Sasa zinc-lead mine in North Macedonia. The report is available to view on the Company's website.

The 2025 Sustainability Report:

As part of its long-term commitment to sustainability, CAML has set a number of performance targets. These are outlined in the 2025 report, with further targets to be added in future as appropriate.

• Versus 2021.
• Female employees increased from 137 in 2021 to 162 in 2025.
• Versus 2020.
• Versus 2020.
• Annual community investment may vary from year to year.

Gavin Ferrar, Chief Executive Officer, commented:

"The past year was one in which we sought to integrate our sustainability activities into our business as a whole. This does not reflect any change in our commitment; on the contrary, it demonstrates that for CAML, sustainability is fundamental to all that we do.

"It also reflects our view that being a responsible producer and employer is not just good ethical practice, but also makes sound business sense. For example, reducing our carbon emissions by introducing our own solar power generation at Kounrad has also reduced our electricity costs; treating staff fairly retains skills within the business, improving productivity and saving on additional training costs; and increasing our use of underground (adit) water, and water recycled from our operations reduces our reliance on surface abstraction thus minimising potential disruption from periods of drought.

"Some elements are simply non-negotiable. We maintain a proactive and stringent approach in these areas, with safety being the clearest example. CAML's goal is to achieve a zero-harm working environment. In 2025, we achieved a lost time injury frequency rate of 0.39, beating our 1.13 target, and demonstrated strong improvement on the previous year.

"Leadership plays a central role in embedding a robust safety culture. As CEO, I have seen first-hand the value of site safety walkthroughs. They provide an opportunity to lead by example and set the tone from the top, but they also allow me to deepen my understanding of how our operations function from day to day.

"Attracting the right people and then providing internal progression opportunities to keep them within the business is critical to our growth. We continue to provide training tailored to each operation, and in 2025 we conducted a comprehensive needs analysis at Sasa to align capabilities with evolving operational requirements. We nurture talent through apprenticeships and sponsorship programmes, provide clear development pathways and maintain fair working conditions.

"Through our foundations and local community work we invested $0.8 million in 2025 providing support to kindergartens, children's and youth centres, contributing to education programmes, as well as responding to specific situations such as the tragic nightclub fire in Kocani in North Macedonia. Beyond direct community support, our commitment to shared value is exemplified by paying attractive wages, prioritising local suppliers and investing in education and training.

"I would like to finish by thanking our employees and all our other stakeholders for their shared commitment to our sustainability goals, as we look forward to 2026 for another year of progress towards our long-term targets."
