Key highlights

• Cyprium Metals has commissioning under way for the Phase 1 restart of its Nifty Copper Complex in Western Australia.

• Heap leach operations began during the quarter for the first time in almost 20 years, with refurbishment continuing.

• A funding package of up to A$83 million supports the restart and the growth case for the project.

Cyprium Metals (ASX:CYM) ended the September quarter with commissioning under way for the Phase 1 restart of the Nifty Copper Complex in Western Australia. Heap leach operations began during the quarter for the first time in almost 20 years, and refurbishment and commissioning progressed across the solvent extraction and electrowinning (SX-EW) plant.

The company expects first copper cathode during wet commissioning and ramp-up. It reported A$37.6 million in cash at the end of September. "First cathode at Nifty is imminent," executive chairman Matt Fifield said, though no production date has been confirmed in the material reviewed.

The funding package

On 30 October, Cyprium announced a staged Debt and Equity package of up to A$83 million. It includes an institutional Placement of about A$20.7 million before costs, through roughly 62.8 million shares at A$0.33 each, and a planned share purchase plan of A$5 million.

Cyprium also signed a term sheet with existing senior lender Nebari Natural Resources Credit Fund II for a proposed US$40 million extension, split into a US$25 million Tranche 2 and a US$15 million Tranche 3. The parties agreed a 30-business-day exclusivity period, and Tranche 2 is expected to close in the fourth quarter of 2026, subject to documentation and conditions.

Where the money goes

Tranche 2 would support final design for an SX-EW expansion, selected long-lead items and early works, plus the open-pit and concentrator definitive feasibility study (DFS), technical studies and resource drilling. Tranche 3 would fund the expansion itself but depends on further Due Diligence and a final Investment decision.

The funding headline is therefore a ceiling. Only the placement commitments are described as firm, while the debt is subject to binding documents.

Commissioning details

Phase 1 targets cathode capacity of about 6,000 tonnes a year from existing heap leach and SX-EW infrastructure. Cyprium has installed 212 production and monitoring wells for direct injection leaching. The initial area gives access to about 1.7 million tonnes of material, expected to support six to eight months of leaching at projected recoveries.

Mechanical refurbishment of the solvent extraction plant was substantially complete, and anode installation in the electrowinning plant was about 80% complete at the time of reporting. Some commissioning was delayed after existing high-voltage components failed during testing and needed replacement, which shows the practical risks of restarting ageing infrastructure.

The growth case

Beyond Phase 1, Cyprium is assessing expansion of SX-EW capacity to about 20,000 tonnes of cathode a year. That would require more copper-bearing leach feed, potentially from accelerated leaching of existing heaps, shallow oxide material in a proposed open pit and oxide mineralisation in historical waste dumps. Updated Nifty Mineral Resources and Ore Reserves are targeted for the first half of 2027.

Why it matters

Restarting a known copper asset can be faster than building a new mine, which is attractive when copper Supply is tight. Yet restarts carry commissioning risk, and the expansion case is not yet backed by a completed DFS or investment decision. Heap leach and SX-EW operations also depend on reliable acid supply, and Cyprium noted that sulphuric acid deliveries to Nifty were under way. Acid costs and availability can influence operating margins for this type of operation, so investors may want to see how the company manages that input once production begins. Investors may also look for details on cathode sales arrangements, including who will buy the copper and on what commercial terms.

What to watch

Investors should watch for first cathode, ramp-up rates, completion of the Nebari documents and the SPP outcome.
