Notes to Editors

Halo Minerals PLC is the 100% owner of the Playa Verde project, an advanced copper tailings project focused on reprocessing metal rich historic tailings which have accumulated onto a beach located in the Atacama region of Chile. The project is a technically de-risked and in October 2025 received unanimous approval for its EIA from the Chilean Government's Ministerial Committee.

Playa Verde has a JORC compliant resource of 53.4 Mt @ 0.24% Cu, which includes reserves of 32.2 Mt @ 0.25% Cu, and is updating its DFS for dredging and retreatment initially targeting the reserves of ore located on the beach followed by up to a further 21 Mt of ore contained in the western berm and shoreline area. The project is well placed with significant upside in securing the rights to process up to a further 100 Mt of potential offshore resource which originated from the same historical mining operations as the onshore resource.

Halo Minerals plans to advance the Playa Verde project on an accelerated timeline to production with funds raised expected to take the project to a final investment decision. Financial analysis estimates operating costs of only $2.19 per pound of copper produced, with the processing of the reserves having an NPV10 of US$ 154.1 million and an IRR of 50.9% after tax from a 7 year life of mine to produce the 32.2 Mt of reserves (based on static commodity price assumptions of $5.30/lb Cu and $4,300/oz Au).

The Company's philosophy is "Mining with a difference" working with the community to detoxify the region, returning the re-treated beach back to the local community whilst economically producing key strategic and battery metals to the benefit of all stakeholders.
