Core Lithium Finniss Project Restart Strategy and Operations Update

Understanding Core Lithium's Northern Territory Advantage

The Core Lithium Finniss project represents a strategic departure from Australia's lithium mining concentration in Western Australia, offering unique positioning advantages that could reshape the nation's critical minerals supply chain. Located just 88 kilometers from Darwin Port, this operation provides unprecedented access to Asian battery markets while leveraging the Northern Territory's emerging mining infrastructure. Furthermore, this positioning aligns with broader australian lithium innovations emerging across the continent.

The project's geographic positioning creates substantial logistical benefits compared to traditional Western Australian operations. While major WA lithium mines typically face transport distances of 200-500 kilometers to reach Fremantle Port, the Finniss operation can deliver spodumene concentrate directly to Darwin's deep-water facilities within hours of processing completion.

Geographic and Logistical Benefits

Darwin Port's strategic location provides 15-20% shorter shipping times to key Asian manufacturing centers compared to routes from Fremantle. This proximity advantage translates to estimated cost savings of $15-25 per tonne for concentrate shipments, primarily through reduced overland transport requirements and elimination of secondary handling procedures.

The port infrastructure has been specifically enhanced for critical minerals exports, featuring:

• Deep-water berth access enabling year-round vessel loading
• Direct shipping lanes to Japan, South Korea, China, and Vietnam
• All-weather operational capability reducing seasonal transport disruptions
• Specialized handling equipment for spodumene concentrate storage and loading

This infrastructure investment positions Darwin as Australia's northern gateway for critical minerals trade, particularly benefiting early-stage producers seeking competitive transport solutions.

Project Scale and Resource Quality

The Core Lithium Finniss project encompasses a substantial resource base of 15.2 million tonnes at 1.26% lithium oxide, distributed across multiple deposits within the 500-square-kilometer Bynoe Pegmatite Field. This resource foundation supports projected mine life exceeding 20 years, substantially above the 10-15 year average for comparable Australian operations. Additionally, this extensive planning approach reflects modern mine planning principles being adopted across the industry.

The project's grade specifications place it competitively within industry standards, with processing designed to produce battery-grade spodumene concentrate containing 6%+ lithium oxide. This specification meets stringent requirements for lithium hydroxide production, the preferred feedstock for high-performance battery cathode materials.

How Does the Grants Deposit Transform Finniss Economics?

Recent optimisation of the Grants deposit mine plan represents a fundamental shift in project economics, delivering $35-45 million in pre-production capital savings while accelerating revenue generation timelines. The updated approach eliminates concurrent development of underground infrastructure, focusing initially on open pit extraction to depths of 145 meters below ground level.

Updated Mine Plan Financial Impact

The revised Grants strategy achieves revenue acceleration through an aggressive one-month timeline from mining mobilisation to first ore delivery. This timeline compression contrasts sharply with industry-standard commissioning periods of 3-6 months, providing substantial working capital advantages during the critical restart phase.

Key economic benefits include:

• Capital deferral: Underground development postponed until pit resources exhausted
• Revenue acceleration: Cash flow generation within 30 days of operations commencement
• Processing optimisation: Existing infrastructure fully utilised without idle asset carrying costs
• Risk mitigation: Reduced financing requirements during volatile lithium price environments

The financial modelling demonstrates that this approach improves project internal rate of return by approximately 2-3 percentage points while reducing peak funding requirements by $15-20 million compared to simultaneous open pit and underground development scenarios.

Ore Reserve Enhancement Details

Comprehensive geotechnical review enabled significant reserve expansion at the Grants deposit, with updated specifications showing 1.53 million tonnes at 1.42% lithium oxide. This represents a 44% increase in contained lithium content, achieved through advanced slope stability modelling and pegmatite structural characterisation.

The deeper pit design required innovative approaches to water management, wall stability, and access road engineering. Geotechnical analysis confirmed safe extraction parameters through:

• Advanced slope monitoring systems providing real-time stability assessment
• Dewatering infrastructure managing seasonal groundwater variations
• Bench design optimisation ensuring long-term structural integrity
• Equipment access protocols maintaining operational safety at increased depths

These technical achievements demonstrate the feasibility of extracting higher-grade ore from pegmatite formations while maintaining operational safety standards consistent with modern mine planning practices.

What Role Does the BP33 Deposit Play in Project Viability?

The BP33 deposit constitutes approximately 57% of total Finniss resources, containing 8.7 million tonnes at 1.38% lithium oxide. This substantial reserve provides operational flexibility through underground extraction methods, complementing the initial open pit focus at Grants while ensuring long-term production continuity.

High-Grade Resource Characteristics

BP33's 1.38% lithium oxide grade exceeds industry averages for spodumene pegmatite operations, typically ranging from 1.2-1.35%. This grade premium translates to processing advantages through:

• Reduced waste ratios in concentration circuits
• Lower per-unit processing costs due to higher head grades
• Superior concentrate yields approaching 85-90% recovery rates
• Product specification consistency maintaining battery-grade quality standards

The deposit's vertical to sub-vertical orientation favours underground extraction using conventional hard rock mining methods, including load-haul-dump vehicles and in-hole drilling equipment standard throughout Australian underground operations.

Production Optimisation Strategy

The dual-deposit approach enables strategic production sequencing based on market conditions, equipment availability, and operational requirements. During periods of strong lithium demand, both deposits can contribute ore to maximise processing plant utilisation, while market downturns allow selective mining from the most economically attractive source.

Underground mining at BP33 typically achieves:

• 85-92% ore recovery rates versus 75-85% for open pit operations
• Consistent production rates unaffected by weather conditions
• Lower surface disturbance supporting environmental compliance objectives
• Extended mine life through access to deeper, higher-grade pegmatite zones

This operational flexibility provides Core Lithium with portfolio optionality rarely available to single-deposit operations, particularly valuable during volatile commodity price cycles.

Why Did Core Lithium Suspend Operations and What's the Restart Plan?

Core Lithium suspended Finniss operations in January 2024 following significant lithium price declines that rendered continued production economically unviable. Lithium carbonate equivalent prices fell from peaks exceeding $60,000 per tonne in 2022 to ranges of $10,000-$20,000 per tonne throughout 2023-2024, compressing margins below sustainable levels for most producers.

Market-Driven Suspension Analysis

The suspension decision reflected comprehensive cash flow analysis determining that operational costs exceeded revenue projections at prevailing market prices. For spodumene concentrate producers, typical cost structures include:

• Mining costs: $8-12 per tonne ore processed
• Processing costs: $800-1,200 per tonne spodumene concentrate
• Transportation costs: $200-400 per tonne concentrate
• Total cash costs: $1,200-1,800 per tonne lithium oxide equivalent

At 2024 lithium prices below $15,000 per tonne, margin compression made continuation impossible without substantial capital injection or cost structure reorganisation.

Comprehensive Restart Strategy

The restart study, expected to complete by mid-2025, incorporates lessons learned from the suspension period while positioning the operation for sustainable profitability during lithium market recovery. Key strategic elements include:

Infrastructure Optimisation:

• Selective equipment upgrades targeting processing efficiency gains
• Maintenance protocol updates incorporating advanced predictive technologies
• Supply chain rationalisation reducing consumable and utility costs
• Labour structure optimisation reflecting post-suspension market realities

Capital Efficiency Measures:

• Pre-production cost reduction of $35-45 million through Grants optimisation
• Phased recommissioning spreading restart costs over 6-12 months
• Working capital minimisation through accelerated revenue generation
• Financing flexibility accommodating various market recovery scenarios

Industry precedent suggests successful lithium operation restarts typically correlate with sustained pricing above $18,000 per tonne lithium carbonate equivalent, providing adequate margins for capital recovery and operational sustainability.
