Halo Minerals PLC (AIM: HALO), the copper development company focused on extracting critical minerals from legacy mining waste, is pleased to announce that its 100%-owned subsidiary, Minera Playa Verde SpA, has formally filed an application with the Delegado Provincial de Chañaral ("Provincial Delegate") for authorisation to conduct mining activities on Playa Grande de Chañaral under Article 17 Nº 1 of the Chilean Mining Code (the "Application").

Highlights:

·    The Application requests permission to conduct mining activities on the beach areas containing historic tailings deposits and follows the EIA approval which was favourably granted in October 2025.

·    Subject to permit approval, Halo is on track to commence site works at Playa Verde before the end of 2026.

Andrew Dennan, Chief Executive Officer of Halo Minerals, comments:
"The filing of this Application is a key regulatory step required to commence operations at Playa Verde and it is a highly significant milestone for the company. With the Project´s environmental approval already secured, this filing follows the sequence of remaining regulatory consents to enable operations.

"Playa Verde is a unique opportunity to reprocess metal rich historic tailings to produce LME Grade A copper cathodes and a copper - gold concentrate from an at-surface, low-capex project in a Tier-1 mining jurisdiction whilst delivering meaningful environmental detoxification to the Chañaral Bay area.

"We look forward to updating shareholders as the permit process progresses."

Summary of Application:

·  Environmental Approval Secured: The Project already holds a favourable environmental qualification, per Resolución Exenta Nº202599101932 dated 15 October 2025 from the Committee of Ministers.

·    Permit Filed: Further to the receipt of the favourable environmental qualification, Minera Playa Verde SpA has now submitted the Application to the Provincial Delegate of Chañaral, requesting permission to conduct mining activities on beach areas containing historic tailings deposits.

·    Playa Verde Project: The Application relates to Halo's Playa Verde Project (the "Project"), located in the Atacama Region, Chañaral Province. The beach hosts mineralised sands with copper content derived from historic tailings discharged into the Salado River basin where the Project has a defined 53Mt JORC compliant resource at 0.24% Cu which includes Ore Reserves of 32Mt at 0.25% Cu.

·    Legal Basis: Article 17 Nº 1 of the Mining Code requires written permission from the Provincial Delegate to carry out mining activities in close proximity to urban areas as well as public roads. The application complies with all requirements of Article 4 of the Mining Code Regulations.

Next Steps:

Following submission, the Provincial Delegate will review the Application in accordance with the Mining Code. The Company will continue stakeholder engagement with local authorities and communities in Chañaral.

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 ~100Mt of offshore potential 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.
