Recap of Core Lithium and its Finniss Lithium Project

Core Lithium’s investment case centres on the Finniss Lithium Project. The project, which CXO owns 100% of, lies in the Northern Territory, close to Darwin Port with well-established infrastructure and logistics. The project moved rapidly from discovery in 2016 to production in 2022, before being placed on care and maintenance in early 2024 following a sharp collapse in lithium prices. That was never meant to be the end of the story of Finniss, but there was only so much CXO could do given lithium prices were in the toilet.

Still, it worked behind the scenes, doing work behind the scenes to lower the costs and a 2025 Restart study showed a lower-cost operation was possible. The study delivered significant capital and operating efficiencies, including pre-production capex reductions of $35–45 million and meaningful cuts to mining and processing costs. The study also delivered significant capital and operating efficiencies, including pre-production capex reductions of $35–45m and meaningful cuts to mining and processing costs.

Despite these improved economics, the project remained in limbo throughout 2025 and early 2026. Core Lithium made clear that a restart would only proceed once both lithium prices and funding conditions were supportive. But now this is the case.

An FID on Finniss has been made!

This morning Core Lithium’s, unveiled a decision to make an FID and formally commit to restarting Finniss, alongside securing funding to execute the plan – US$120m/A$170m worth of funding. The FID reflects management’s view that project economics are now sufficiently robust, even in a volatile lithium pricing environment.

Lithium prices have shown signs of recovery from 2024 lows, and Core’s strategy is to position Finniss as a low-cost producer capable of operating through the cycle. By lowering operating costs and increasing recovery rates, the project is better insulated against downside scenarios, while still offering leverage to higher prices.

Glencore is involved

Glencore is one of the most prominent mining companies in the world and was already involved with CXO and its Finniss Project. Back in February, CXO and Glencore entered into a binding agreement to exchange ~5,100 tonnes of spodumene concentrate stockpile to Glencore for US$10m in cash.

Granted, this transaction is not a traditional offtake agreement. It was a one-off (or short-term) stockpile sale at spot-linked pricing, and importantly, it did not cover future production from Finniss. In fact, Core had previously terminated its long-term offtake agreement with Ganfeng Lithium in 2025, leaving all future production uncontracted and available for new arrangements.

But it was still a big deal as it was done to help CXO re-establish its logistics chain to Darwin. Moreover it demonstrated product quality and market demand, potentially serving as stepping stone toward future offtake agreements or financing discussions.

This morning, CXO investors learned Glencore was now helping to fund the restart of Finniss, as part of a broader consortium. Moreover, Glencore is now involved commercially through a marketing agreement. This gives it a role in selling and distributing Finniss spodumene into global markets, leveraging its trading network.

Yes, this is still not a traditional locked-in offtake agreement. Glencore is not taking fixed volumes over long durations, there is no binding take-or-pay style contract underpinning project cash flows and CXO retains the ability to sell into spot or multiple counterparties.

The presence of Glencore in the funding stack adds credibility and reduces execution risk.

So now what?

Construction activity is expected to begin almost immediately, because this is not a greenfield build. The Finniss site already has a largely built and previously operating plant, along with established infrastructure, mining areas and logistics routes to Darwin Port. What CXO has money for is a recommissioning and optimisation phase rather than full construction. That means early works such as site mobilisation, contractor engagement, plant refurbishment, and pre-strip mining can begin within weeks of FID and funding close, rather than months.

In practical terms, this suggests visible on-site activity through the June quarter of 2026 and the company named this quarter. It is important to note that the company had already done much of the preparatory work during the care and maintenance period, including engineering updates and mine plan optimisation, so the lag between FID and physical restart is relatively short compared to a typical new mine.

OK, but what about mining itself?

The restart itself is expected to be staged. Mining is likely to recommence first, particularly at the Grants open pit, which is the lowest-risk and quickest source of ore. Processing plant recommissioning would follow, including testing, ramp-up and recovery optimisation.

Based on typical timelines for brownfield lithium operations and Core’s own prior guidance, first production could realistically occur within three to six months of FID, pointing to late 2026 for initial spodumene output.

However, reaching steady-state production will take longer. Lithium operations typically require a ramp-up period to stabilise recoveries, throughput rates and cost performance. This could extend into 2027 before Finniss is operating at its targeted nameplate capacity and delivering consistent cash flow.

CXO’s strategy is to bring the operation back online quickly, generate revenue early, and then progressively optimise and expand. This reduces funding risk and shortens the payback period, which is particularly important given the volatility in lithium prices.

Conclusion

Today is good news for CXO investors with an FID being made to restart Finniss and funding being secured.

Construction and restart activities should be imminent, with first production likely before the end of 2026. The more meaningful milestone for investors, however, will be when the operation demonstrates stable, low-cost production at scale, which is more likely to be a 2027 story.
