Copi critical minerals approval: design and infrastructure notes for mine planners
Reviewed by Joe Ashwell
First reported on Australian Mining
30 Second Briefing
RZ Resources has secured New South Wales Government development approval for its $693 million Copi critical minerals project in the state’s far south-west, about 75km north-west of Wentworth and 180km south-west of Broken Hill, targeting first production in early 2029. The project will produce zircon, rutile and rare earth elements from strandline-style mineral sands, positioning Copi within an established Murray Basin mining corridor with existing haulage and export infrastructure. Geotechnical and civil design will need to address arid-zone tailings storage, groundwater management and long-distance power and road access in a remote environment.
Technical Brief
- Development approval triggers detailed mine planning, tailings storage design and environmental management plan finalisation.
- Location in NSW far south-west implies long supply chains for reagents, fuel and maintenance support.
- Arid climate conditions will necessitate high water-recovery tailings systems and robust dust suppression design.
- Remote setting increases reliance on all-weather access roads and resilient power transmission or on-site generation.
- Regulatory approval at state level de-risks subsequent financing, EPC contracting and long-lead equipment procurement.
- Similar Murray Basin mineral sands operations provide analogue data for geotechnical parameters, pit slope design and tailings behaviour.
Our Take
RZ Resources’ planned ASX listing at a reported ~$1 billion valuation, noted in February coverage, suggests that securing approval for a A$693 million asset like Copi could materially de‑risk its equity story and improve terms for any future debt or export-credit support.
With first production only targeted for early 2029, Copi’s long lead time means it will likely compete for contractors and equipment with other large Australian critical-mineral builds flagged in our Mining projects coverage, which can push up EPC and mining services pricing in remote regions such as far south‑western NSW.
