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.
