- Core Lithium plans 20-year mine life at Finniss project
- Operational costs cut by over 30%, boosting margins
- Focus on scalable, long-term underground mining model
Core Lithium (ASX:CXO) has released results from its Restart Study, unveiling a long-life, low-cost development plan for its Finniss Lithium Operation in the Northern Territory. The study confirms a 20-year mine life and introduces significant cost reductions, improved plant efficiency, and a scalable underground mining strategy, marking a major milestone for the company’s future in the lithium sector.
Key findings from the study highlight an optimized production plan, with 94% of the first decade underpinned by Ore Reserves. A shift from open pit to underground mining enables access to high-grade, continuous orebodies that remain open at depth, reducing surface impact and extending operational life.
Mining costs are projected to decrease by approximately 40%, falling to $63–$72 per tonne, while processing costs drop by 33% to $40–$46 per tonne. These savings position Finniss as one of the lowest-cost global spodumene producers. Annual concentrate production is estimated to rise by 7% to around 205,000 tonnes (SC6 equivalent), aligning with increased lithium demand driven by global electrification trends.
The processing plant has undergone flow-sheet simplification and debottlenecking, boosting throughput by 20% without requiring major capital investment. Recovery rates have improved to 78%, contributing to a high-quality, coarse-grained concentrate product. Importantly, Core Lithium has taken full ownership of the plant and related infrastructure, enhancing operational control.
Financially, pre-production capital requirements have been slashed by 29% to $175–$200 million. The restructured plan is expected to generate around $1.2 billion in free cash flow over its life, highlighting its potential to deliver substantial returns relative to initial capital outlay.
The company is now exploring funding avenues for the project restart. According to management, the focus remains on selecting strategies that limit shareholder dilution while ensuring access to long-term capital. A final investment decision will be subject to market conditions and board approval.
With its inclusion in the ASX300 index, Core Lithium now stands among notable peers offering growth exposure within Australia’s broader equities market. For investors exploring ASX dividend stocks, resource-focused names within the ASX300 index may be of growing interest, particularly those with long-term project visibility and cost efficiency.
The Restart Study reinforces Core Lithium’s potential role in Australia’s critical minerals sector, while also hinting at job creation and regional development opportunities in the Northern Territory. The company’s long-term strategic plan lays a foundation for sustainable lithium production amid evolving energy transition dynamics.
