Halo Minerals Targets 2026 FID and 2028 Production on EIA Approved Chilean Copper Project - Article | Crux Investor

Highlights

·    Advanced, technically de-risked copper tailings re-treatment project in the Atacama region of Chile, with a 53.4 Mt JORC compliant resource at 0.24% Cu.

·    Highly economic project based on 32.2mt of Ore Reserves: post-tax NPV10 of $154.1million and IRR of 50.9% and commodity price assumptions of $5.30/lb Cu and $4,300/0z Au.

·    Spot copper and gold prices currently materially above the assumptions used in the Competent Persons report. Applying the same CPR methodology at approximately $6.35/lb Cu and $4,300/oz Au respectively indicates NPV10 of approximately $241million and IRR of 73%.

·    Maritime concession process initiated, targeting access to potentially significant additional tailings within the footprint of Halo's existing mining license area extending into Chañaral Bay.

·    Mining use of beach license filing and ancillary permit preparation underway, following unanimous approval and receipt of written resolution of the project's Environmental Impact Assessment in October 2025.

·    Development funding discussions progressing, with the Company targeting a layered funding approach that may include offtake/prepay finance, vendor finance, royalty/stream structures, project debt and other strategic sources of capital.

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.
