Halo Minerals (AIM:HALO) has contracted BIOS Mining & Infrastructure to position the Playa Verde Project in Chile towards a final investment decision (FID).
BIOS Mining & Infrastructure will conduct a mineral processing plant flowsheet design review and optimisation studies. The company has worked with the project for more than 10 years and has detailed knowledge of Halo’s development plans.
The scope of work includes evaluating a complementary process circuit to reduce arsenic levels in final tailings to support compliance with commitments under the project’s approved environmental impact assessment.
BIOS Mining & Infrastructure will also review the flowsheet more generally and provide suggestions on ways that this can be optimised for efficiencies and potential to reduce overall capital expenditure spend.
Halo Minerals CEO Andrew Dennan says BIOS Mining & Infrastructure’s work to review and optimise the mineral processing plant flowsheet and support the company on ancillary permit applications is an “important” step in progressing the project.
The company also confirms that the annual mining licence fees for the project’s six mining concessions have been paid.
Playa Verde was acquired by Halo Minerals in March 2025 and is considered an economic project to re-treat tails and produce copper and gold. The project’s resource totals 53 million tonnes @ 0.24% copper for 126,000 tonnes of copper.
The project is to be mined using an electric single wheeled suction dredge ore processed via leaching. Flotation is targeting 5 million tonnes per year of ore processed, with a 14,000 tonnes per day capacity with 72% copper recovery.
Halo Minerals is focused on producing key strategic and battery metals through the reprocessing of low-risk metal-rich surface accumulated legacy mining waste projects.
