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.

• 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.
