Core Lithium Moves Closer to Revenue Stage as Finniss Plant Produces Initial Spodumene Output

Core Lithium has produced its first spodumene concentrate from the Finniss processing plant. The milestone advances the staged restart of the Finniss Lithium Operation. 

Core Lithium Ltd (ASX: CXO) achieved the result after targeted plant upgrades. Mining activities at Grants Open Pit restarted in May. Crushing activities also recommenced in August. 

These steps created sufficient crushed ore stockpiles for processing. The company said plant commissioning and optimisation remain underway. Core Lithium moves closer to revenue stage as production progresses towards sustained operations.

Core Lithium Finniss Plant Spodumene Output Marks Key Milestone

The first concentrate follows the restart decision announced earlier this year. Core reached the milestone within six months of the Final Investment Decision. The result also matches Core’s September Quarter 2026 target. The company remains focused on achieving reliable and sustained production. Key progress includes:

• First spodumene concentrate produced from the recommissioned processing plant.
• Plant commissioning and optimisation activities continuing.
• Processing plant restart completed on schedule.
• Restart achieved within six months of FID.
• First shipment targeted for the December Quarter 2026.
  These milestones provide a clearer pathway towards revenue generation from Finniss.

Core Lithium Initial Spodumene Output Follows Plant Upgrades

The processing plant underwent targeted upgrades before recommissioning. These upgrades aimed to remove circuit bottlenecks and improve recovery. Screen refurbishments formed part of the improvement programme. 

Core also enhanced the rolls crusher and tails thickener circuits. The ferrosilicon distribution system received improvements as well. Crushing and DMS operations were consolidated into one control room. 

Core expects these changes to improve mineral liberation and recoveries. The upgrades should also increase plant throughput capacity by approximately 20% to 1.2 Mt per annum.

Grants Support Core Lithium’s Production Pathway

Grants remain central to the near-term restart strategy at Finniss. The open pit provides a rapid source of ore feed. This supports processing activities while helping generate early cash flow. Core is also advancing BP33 underground mine development in parallel. The company’s operational priorities remain focused on several areas:

• Safe and disciplined mining operations at Grants.
• Continued commissioning and optimisation of the processing plant.
• Ongoing underground development at BP33.
• Building operational reliability and sustainable production.
• Maintaining the existing logistics chain for future shipments.
  This approach supports the staged restart while development work continues across Finniss.

Core Lithium Moves Closer To Revenue Stage With Shipments Ahead

Core continues targeting its first shipment during the December quarter of 2026. The logistics chain is already operational, supporting this objective. Production and shipments are expected to continue into 2027. 

The company said the first concentrate reflects disciplined execution of its restart plan. Managing Director Paul Brown described the achievement as another significant milestone. 

He highlighted funding, mobilisation, mining recommencement and plant commissioning. Core also said the restart remains on schedule and on budget. The company will now focus on plant optimisation and operational reliability.

What The Finniss Restart Means For Core Lithium

The first spodumene concentrate provides a tangible operational marker for Core Lithium. It confirms processing activities have progressed beyond commissioning preparation. 

However, the plant remains in its commissioning and optimisation phase. Core must still demonstrate reliable and sustained production. Throughput, recovery and operational reliability will remain important measures. 

The targeted first shipment adds another near-term milestone for investors. The company also continues developing BP33 underground operations. Core Lithium moves closer to the revenue stage as Finniss progresses through its restart and ramp-up process. For more such updates, visit Mining Herald.
