October 24, 2024
Metals Australia Limited (“Metals Australia”, the “Company” or “MLS”) is pleased to report its activities for theQuarter ended 30 September 2024 (“Quarter”):
Corporate
- The Company’s cash balance at the end of the Quarter was $16.02 million (Q4 $17.35 million), following net outflows of $1.33M, which included $1.17M spent on exploration, metallurgical test work and project studies. Staffing, consultant and administration costs, offset by interest on fixed term deposits resulted in net outflow of $159 K for the quarter. Please see details in the Appendix 5b.
Highlights
- Commenced and completed phase 1 of an exploration campaign at the Corvette River Project in the James Bay region of Quebec Canada1. The program was aimed at advancing three highly prospective Gold, Silver and base metals projects – Felicie, West Eade and East Eade. Post quarter end the company announced results from the program, further enhancing the potential of the three project areas at a time when gold prices have reached all-time highs. Further work for a Phase 2 field program is being planned.
- Announced comprehensive exploration plans for three Critical and Precious metals projects in Australia2, representing the beginning of the most significant exploration period in the company’s history. The projects include Warambie in WA’s Pilbara region (prospective for Gold, base metals and Lithium), Big Bell North Gold in WA’s Murchison Region and the Warrego East Copper, Gold and Bismuth project in the NT.
- Launched the Warambie aircore drilling program in the Pilbara in September3, following receipt of approvals from the regulator and land holder and the award of a competitively bid drilling tender.
- Launched Gravity and Soil sampling programs at the Big Bell North Gold project in the Murchison3, which together with an extensive aeromagnetic survey, recently completed, represented the most significant exploration ever undertaken on the tenements. Post quarter end, the company announced significant drill targets had been identified and that a 4500m air core drilling program was contracted to begin.
- Significantly advanced its Lac Carheil Graphite project in Quebec, Canada4 – Provided a comprehensive update on the Metallurgical test work program, the design of the Process Flow Sheet for the Flake graphite concentrates plant and the prefeasibility study during the quarter. Significant time was spent in Canada by the CEO, advancing the project with Government and key stakeholder groups. The Company also added to its project land bank, increasing the claims area held by more than 60%. The additional claims extend ground holdings on identified graphite trends as well as land provisioning for the placement of project infrastructure.
- In addition to the above work, the release of the Canadian Federal Governments Critical Minerals Strategy Annual Report 20245 during the quarter further highlighted the significance of our Lac Carheil Graphite project. The growing urgency to develop domestic supplies of graphite, including 5 graphite mines and CSPG refineries, is directly connected to the over 200 GWH of committed battery manufacturing plants in Canada. Four plants are progressing, including one in Quebec (Northvolt) and three in Ontario.
Exploration & Project Development Review
Canadian Projects:
Lac Carheil Graphite – Critical Minerals Project, Quebec, Canada:
During the Quarter the Company applied significant effort to the advancement of its flagship Critical Minerals project. Significant progress was made in key areas4, including metallurgical test work, design of flake graphite concentrates plant process flow sheet and the prefeasibility study for the project. In parallel, considerable engagement was undertaken with government and key stakeholders in Canada and within Quebec. Engagement with government also resulted in submissions for grant funding – both in Canada and the USA, with further applications under development to support funding for the project. The land holding for the project was also extended by 62%, by pegging additional claims, including extensions of identified graphite trends and provision of land for project infrastructure placement. The company continues to advance consultation in support of its drilling permit application, for which an Impact Exploration Assessment was completed and submitted in alignment with new regulatory requirements in Quebec. Consultation discussions in support of the project, including drilling, continue in an open and productive manner with all stakeholders. Metals Australia is aligned with the Canadian and Quebec governments commitment to ensuring that indigenous communities benefit holistically from critical minerals projects.
Further, the Company notes the release of the Canadian Federal Governments Critical Minerals Strategy Annual Report, 20245 and the significance that report attaches to Critical Mineral projects such as ours. A link to the report is available on our website. Of note is the urgency with which Canada is progressing to secure supply of critical and strategic minerals for a rapidly advancing battery manufacturing base. The report notes the commitments of major battery and car manufacturers to rapidly progress the production of over 200 GWH of battery production capacity, annually. The report outlines the requirement for 5 graphite mines and 5 coated spherical purified graphite plants (CSPG) – all of which are required to help supply the capacity planned, in construction or already in operation. The environment for critical mineral project development in Canada and the USA is rapidly accelerating – which positions the Lac Carheil Graphite project as one of increasing significance, given its potential to be one of the largest, highest grade graphite projects in North America.

Metals Australia
Overview
Metals Australia (ASX:MLS) is a mineral exploration company with a high-quality portfolio of advanced battery minerals and metals projects in Tier 1 mining jurisdictions of Western Australia and Canada. The portfolio comprises two critical minerals projects in Quebec, Canada — the Lac Carheil flake graphite project and the Corvette River lithium (and gold) project. The Australian portfolio comprises four projects: Tennant Creek (copper-gold) in the Northern Territory and Warrambie (lithium, nickel-copper, gold), Murchison (gold) and Manindi (lithium, vanadium-titanium, zinc) – all in Western Australia.
The push for net zero targets and the call from policymakers to transition to cleaner energy has intensified the focus on electric vehicles (EVs) and battery storage. The EV automakers and battery manufacturers, rely on essential materials such as graphite and metals, including lithium, nickel, copper and cobalt, to manufacture the batteries that are used in these vehicles and storage batteries generally. This has driven carmakers and battery manufacturers to partner with battery material suppliers under direct off-take agreements. Further, some automakers/battery manufacturers are buying equity stakes in miners, involving them directly in financing decisions for the development of mining projects. This is encouraging for companies such as Metals Australia as it actively advances its projects towards development.
Figure 2 – Graphite is a Critical Mineral required for the mass electrification of auto transportation.
Metals Australia is focused on progressing its flagship Lac Carheil flake graphite project in Quebec, Canada. The project is well-positioned to supply high quality graphite products, including battery-grade graphite to the North American market – including for lithium-ion and EV battery production in the future. The company announced positive sampling results across a 36-km strike length of identified graphite trends at Lac Carheil, including many values over 20% Cg and an exceptionally high-grade sample containing over 63% Cg. The company has planned a drilling program to test new high-grade zones identified from the sampling program, which will form the basis for upgrading the existing Lac Carheil Mineral Resource. An application for the drilling program is progressing with the Quebec regulator. Additionally, the company has recently commenced a Flake Graphite concentrate prefeasibility study with Lycopodium in Ontario and a downstream battery anode plant design with ANZAPLAN in Germany.
Metals Australia is also advancing its lithium, gold and silver exploration project at Corvette River, which is adjacent to Patriot Battery Metals’ world-class lithium project. Further, the company carries out aggressive exploration programs at its other projects, including Manindi, Warrambie & the Murchison in Western Australia and Tennant Creek in the Northern Territory region of Australia.
Metals Australia is well-funded to complete all its planned exploration and project studies. The cash position at the end of Q1 2024 was AU$17.86 million, which we note was higher than the company’s market capital at current share price. Metals Australia benefits from a team of professionals boasting extensive expertise in geology and mining. The appointment of experienced mining executive Paul Ferguson as the CEO is positive for the company. Since joining in January 2024, he has significantly advanced planning and preparation for the exploration, metallurgical test work programs, and design studies required to move its flagship Lac Carheil high-grade graphite project towards development. The Corvette Project has also completed exploration planning and is now fully permitted for drilling and trenching work during the northern hemisphere summer.
Company Highlights
- Metals Australia is rapidly advancing its flag ship Lac Carheil Graphite Project in Quebec, Canada.

Key Projects
Canada
Lac Carheil Flake Graphite Project (MLS 100%)
Conceptual 3D Mining layout from February 2021 Scoping Study (Lac Carheil Project formerly named Lac Rainy Project)
The Lac Carheil Graphite Project is located in eastern Quebec, Canada, a tier 1 mining jurisdiction with access to excellent infrastructure, including hydroelectric power facilities. The project hosts an existing JORC 2012 mineral resource of 13.3 million tons (Mt) @ 11.5 percent graphitic carbon, which was announced in 2020 and a scoping study was completed and reported on in early 2021. Battery test work followed, in Germany, and this demonstrated the Lac Carheil Graphite concentrate could be shaped, purified, coated and used in battery applications with excellent results. Given the above work, the company carried out further field work, recently announcing exceptionally high-grade sampling results from 80 samples on 10 identified graphitic trends across the property. This included a sample containing 63 percent graphitic carbon, and 10 samples containing over 20% Cg. The average grade of the sampling was 11% Cg, which is comparable to the current high-grade resource. The combined strike length of the identified high-grade graphitic zones is over 36 kms. This compares to just 1 km of drilling on 1.6 kms of graphite trend that was utilised to obtain the existing resource. The potential for expanding and upgrading the existing resource remains enormous.

Additional drilling and development studies are either planned or are already underway, including a pre-feasibility study for a high grade Flake graphite concentrate product – which has commenced and a downstream purification options assessment and a scoping study for a battery anode facility in North America, which has been contracted. The company also announced it is contract ready for its planned drilling program and will fast-track the program as soon as permits are received from the Quebec regulator.
Corvette River Lithium Project (MLS 100%)
Corvette River Lithium, gold and silver Project is located in Quebec’s James Bay region Metals Australia recently announced that it is fully permitted to advance an extensive field exploration program across its holdings which include the wholly owned East Pontois, Felicie and West Pontois projects, situated within Patriot Battery Metals' (ASX:PMT) CV Lithium Trend, as well as tenements at West and East Eade in the company's parallel Corvette River South Trend. A field mapping and sampling program concluded last year and identified large, potentially lithium-bearing pegmatites immediately along strike from Patriot Battery Metals’ world-class lithium pegmatite discoveries. Additionally, the company has flagged significant gold and silver samples from its review of work previously completed across the field as is illustrated in the diagram below.Figure 5 – The Corvette Projects in the James Bay region of Canada.

Rock Bottom: Strategic Window for Ground-level Lithium Investment in 2025
When lithium prices hit bottom, savvy investors know that’s exactly where the next big discovery begins — literally. Beneath the surface of global markets and remote exploration grounds, new opportunities are forming in the wake of a sharp price reset and renewed geopolitical urgency.
Macroeconomic and policy shifts in 2025 are creating ideal conditions for those willing to look past the headlines. While volatility in lithium prices has tempered short-term sentiment, the underlying demand trajectory remains strong. With governments reshaping supply chains to reduce reliance on China and accelerate the energy transition, lithium is emerging not only as a critical resource, but as a strategic investment theme with long-term upside.
For investors, this reset isn’t a retreat; it’s a rare chance to get in early, at ground level.
Critical metal for a low-carbon future
Lithium demand is being driven by structural, not cyclical, forces.
Global sales of electric vehicles are expected to reach 17 million units in 2025, up from just 6.6 million in 2021, according to a report from the International Energy Agency. At the same time, the rollout of renewable energy infrastructure has created a parallel boom in demand for lithium-ion batteries in stationary storage applications.
These trends have elevated lithium to the status of a strategic resource. The US, EU, Canada and Australia have all included lithium on their critical minerals lists, with policy frameworks and funding programs aimed at reshoring supply chains and reducing dependence on dominant producers such as China.
New landscape for investors
Three major forces are shaping the lithium market in 2025:
- Geopolitical realignments: China continues to dominate lithium refining and cathode production, but western economies are responding with policies that promote domestic and allied resource development. Africa, in particular, is emerging as a new frontier, offering significant untapped lithium reserves in relatively underexplored jurisdictions.
- Strategic consolidation: Major lithium producers are moving aggressively to secure future output. Rio Tinto's (ASX:RIO,NYSE:RIO,LSE:RIO) $6.7 billion acquisition of Arcadium Lithium, and SQM's (NYSE:SQM) joint ventures in Brazil and Australia reflect a renewed emphasis on long-term control of raw materials. These moves also signal confidence in lithium’s medium- and long-term pricing. Rio Tinto, in particular, remains “consistent in its belief in the long-term outlook for lithium,” according to a June 3, 2025, report from Reuters.
- Price volatility creates opportunity: Spot lithium prices experienced a steep drop in 2023 following the oversupply concerns post-2022 highs. But market watchers are now seeing signs of recovery as supply rationalizes and demand from automakers rebounds. For investors, downturns often mark the most opportune entry point — when high-quality assets are undervalued and underfunded.
Lithium Africa: A strategically aligned explorer
Amid this shifting landscape, junior exploration company Lithium Africa is capitalizing on timing, partnerships and geography. The company is focused on unlocking lithium potential across Africa, with an early focus on pegmatite-rich regions in Morocco, Zimbabwe, Côte d’Ivoire and Guinea — jurisdictions that are fast gaining attention as future pillars of global lithium supply.
Strategic partnership
One of Lithium Africa’s most distinctive value propositions is its technical and financial partnership with Ganfeng Lithium, one of the world’s largest lithium producers. Ganfeng brings deep chemical processing expertise and project development experience, providing critical de-risking support as Lithium Africa advances its early stage projects. Importantly, Ganfeng is matching every dollar raised by Lithium Africa — with $1 raised equating to $2 spent on exploration — an arrangement that reduces dilution, improves capital efficiency and signals external validation of project potential.
Raising capital at the bottom of the cycle
Unlike many juniors sidelined by the recent downturn, Lithium Africa is using the current market reset as a window of opportunity. The company has secured funding during the trough of the lithium cycle, allowing it to acquire prospective tenements at low cost and accelerate fieldwork, while competitors are cash-constrained or inactive. This countercyclical strategy is designed to generate value precisely when assets are overlooked by the broader market.
Efficient exploration for discovery-driven growth
Lithium Africa’s exploration model emphasizes efficiency. The company employs low-cost but technologically advanced geophysical and geochemical techniques to quickly evaluate and rank prospects before committing to intensive drilling campaigns. In regions like Zimbabwe — already home to several lithium occurrences — this approach allows for rapid advancement toward discovery. Should a world-class deposit be delineated, history shows that such a find is recognized and rewarded by both majors and markets, regardless of the broader cycle.
Africa's lithium frontier: Gaining global attention
Lithium Africa is part of a broader wave of explorers turning their attention to the continent. Companies such as Leo Lithium (ASX:LLL,OTC Pink:LLLAF) and Atlantic Lithium (ASX:A11,LSE:ALL,OTCQX:ALLIF) have drawn investor interest for their hard-rock projects in Mali and Ghana, respectively. Africa offers the geological potential, lower entry costs and increasing regulatory clarity that resource developers seek in a post-China supply chain strategy.
However, Lithium Africa’s differentiators — its timing, capital alignment and strategic partnership — set it apart in a competitive field.
Investor takeaway
The lithium market may be entering a phase of short-term volatility, but its long-term trajectory is defined by structural demand growth. For investors, the opportunity lies not just in producers, but in the well positioned explorers who can secure quality ground, deploy capital wisely and advance toward discovery with strong technical backing.
Companies like Lithium Africa, which align with geopolitical supply trends, partner with strategic industry leaders, and commit to efficient, high-impact exploration, offer a uniquely leveraged way to gain early exposure to the next chapter of global lithium supply.

Outstanding High Grade REE Diamond Drill Results
10 June
Beneficiation Delivers 4,480ppm Lithium Clay Concentrate at Red Mountain Project, USA
Latest results reinforce ability to upgrade Red Mountain mineralisation
Astute Metals NL (ASX: ASE) (“ASE”, “Astute” or “the Company”) is pleased to report further positive results from the latest phase of beneficiation testwork for its 100%-owned Red Mountain Lithium Project in Nevada, USA. The results continue to strengthen the Project’s commercial development potential.
Key Highlights
- Follow-up Falcon C beneficiation testwork completed on diamond drill core samples from the Red Mountain Project.
- Sample upgraded from 3,245ppm to 4,481ppm Lithium.
- Successful removal of 51.8% of dense material and concurrent 38% increase in lithium grade.
- Reinforces the April 2025 results indicating that Red Mountain mineralisation may be upgraded using beneficiation.
- Attrition Scrubbing beneficiation testwork now underway for comparison with the Falcon testwork results.
- Leaching testwork to be undertaken on Falcon and Attrition Scrubbing products to confirm reduced acid consumptions.
Following on from the results announced on 22 April 2025, this second phase of Falcon Beneficiation testwork was designed to concentrate lithium-bearing clay and remove unmineralized gangue (waste) in order to decrease mass and increase lithium grade. In a mineral processing context, a reduction in tonnes and volume processed with an increased head-grade typically results in lower processing costs.
This second Falcon testwork program was conducted by Sepro Laboratories (Sepro) and utilised high- clay drill core samples from hole RMDD002 (which intersected 86.9m @ 1,470ppm Li from 18.3m4). This follow-up test was designed to establish how high-clay material performed using the Falcon method, for comparison with results from the previous test conducted on lower grade mineralisation from Red Mountain.
The latest result indicates a strong ability to upgrade mineralisation, achieving a reduction of sample mass by 51.8% with a concurrent increase in lithium grade of 38% (from 3,245 to 4,481ppm Li), with an overall 66.6% lithium recovery. These results compare favourably with the previous round of testwork, exhibiting both a greater upgrade in lithium and reduction in mass, with a substantial 43% reduction in calcium and carbon (interpreted as calcite removal) expected to result in a significant reduction in acid consumption. The Company has commissioned Attrition Scrubbing testwork – another method of beneficiation – for comparison with the Falcon results. Once complete, sample products from both the Falcon and Attrition Scrubbing tests will be assessed for acid consumption in future leachability tests.
Astute Chairman, Tony Leibowitz, said:“The demonstration of a commercial pathway to a lithium product is the natural complement to the establishment of a Mineral Resource. It is for this reason that Astute has actively advanced workflows for both exploration drilling and metallurgical testing at Red Mountain, in tandem. These positive results, which reinforce the previous results from the project, represent the systematic de-risking of what continues to emerge as an important US- based critical metals project.”
Figure 1. Clay-rich RMDD002 drill-core from 160-165ft (3,280ppm Li) used in Falcon beneficiation testwork.
Background
Located in central-eastern Nevada (Figure 4), adjacent to the Grand Army of the Republic Highway (Route 6), which links the regional mining towns of Ely and Tonopah, the Red Mountain Project was staked by Astute in August 2023.
The Project area has broad mapped tertiary lacustrine (lake) sedimentary rocks known locally as the Horse Camp Formation1. Elsewhere in the state of Nevada, equivalent rocks host large lithium deposits (see Figure 4) such as Lithium Americas’ (NYSE: LAC) 62.1Mt LCE Thacker Pass Project2 and American Lithium (TSX.V: LI) 9.79Mt LCE TLC Lithium Project3.
Astute has completed substantial surface sampling campaigns at Red Mountain, which indicate widespread lithium anomalism in soils (Figure 3) and confirmed lithium mineralisation in bedrock with some exceptional grades of up to 4,150ppm Li1,5.
A total of 19 RC and diamond drill holes have been drilled at the project to date for a combined 3,666m. Exploration drilling has been highly successful, with strong lithium mineralisation intersected in every hole for which assays have been received9.
Scoping leachability testwork on mineralised material from Red Mountain indicates high leachability of lithium of up to 98%, varying with temperature, acid strength and leaching duration, and proof-of- concept beneficiation testwork has indicated the potential to upgrade the Red Mountain mineralisation6,8.
About Beneficiation
The primary purpose of beneficiation is to optimise the value of mineralised material by separating unwanted waste material (gangue) from valuable minerals.
Testwork conducted to date at Red Mountain indicates that clay-hosted lithium mineralisation may be upgraded through beneficiation, which seeks to remove coarser grained material, such as particles of sand, that do not contain appreciable lithium8. Successful beneficiation can result in reduced reagent consumption, reduced plant wear and tear, and a reduced environmental footprint.

Pursuit Dispatchs 99.5% Lithium Carbonate Samples to Potential Strategic Partners as Feasibility Studies Progress
Pursuit Minerals Ltd (ASX: PUR) (“PUR”, “Pursuit” or the “Company”) is pleased to announce that high- purity lithium carbonate samples have been dispatched to multiple parties as part of its engagement with prospective offtake and strategic partners. The samples were produced from the Company’s 250tpa Pilot Plant in Salta, Argentina, using synthetic brine chemically identical to that of the Rio Grande Sur Lithium Project.
HIGHLIGHTS
- Final product assays confirm 99.5% lithium carbonate purity, upgraded from pilot output via bench scale processing.
- Certified samples dispatched to multiple potential offtake and strategic partners for qualification.
- Feasibility study progressing for low cost, 5,000tpa operation at Rio Grande Sur.
- Ongoing small batch lithium carbonate production to support offtake qualification while preserving capital discipline in current market conditions.
- Pursuit continues to advance its dual-pronged growth strategy progressing Rio Grande Sur while accelerating the evaluation of strategic gold, silver, and copper acquisitions in Argentina.
Figure 1 – Pursuit’s 99.5% Li₂CO₃ Sample Ready for Dispatch to Potential Offtake Partners
In relation to the dispatch of samples, Pursuit Managing Director & CEO, Aaron Revelle, said:
“Achieving 99.5% lithium carbonate purity is a major technical milestone for Pursuit and a clear demonstration of the capability embedded within our flowsheet, team, and pilot plant infrastructure. It not only validates the compatibility of our process design with Rio Grande Sur brines but also confirms our ability to deliver a consistently high-quality product suited to a wide range of industrial and energy storage applications. Dispatching these samples to potential offtake partners is a critical first step in our commercialisation pathway, enabling product qualification and accelerating engagement with strategic customers in tough market conditions. As we transition into the next phase of development, our focus is firmly on advancing feasibility for our 5,000tpa operation and securing long-term partnerships that will underpin the future production and growth of the Rio Grande Sur Project.”
Initial pilot production at Pursuit’s 250tpa Pilot Plant in Salta successfully produced 15 kilograms of lithium carbonate at 98.9% purity, validating both the compatibility of the Rio Grande Sur brine and the efficiency of the Company’s conventional processing flowsheet. To enhance product quality and simulate potential refinement steps at commercial scale, a portion of this material was further treated at bench scale using fractional crystallisation (FX) and ion exchange (IX) techniques. These post processing steps upgraded the product to 99.5% purity, meeting established benchmarks for technical-grade lithium carbonate.
The final product assays confirm not only the effectiveness of Pursuit’s downstream purification strategy but also the scalability and robustness of its broader flowsheet. This achievement represents a critical milestone on the path to commercial readiness supporting key feasibility assumptions, validating end product quality, and enabling active engagement with prospective offtake partners.
Pursuit is well positioned to undertake additional small-batch production as required to meet partner qualification needs and advance strategic discussions. Furthermore, it demonstrates Pursuit’s capability to produce high-purity lithium carbonate suitable for industrial use, with potential to meet battery-grade specifications through additional refinement.

Ore Reserve Quadruples for Rhyolite Ridge Project; Reaffirms Robust Project Economics
Ioneer Ltd (ASX: INR, Nasdaq: IONR) (Ioneer) is pleased to announce a 308% upgrade to the Ore Reserve estimate for its 100%-owned Rhyolite Ridge Lithium-Boron Project (‘Rhyolite Ridge’ or the ‘Project’) in Nevada, USA, alongside updated Project economics.
- Rhyolite Ridge Ore Reserve more than quadrupled from 60 million tonnes in 2020 to 247 million tonnes, delivering a mine life of 95 years
- Ore Reserve now contains a total of 1.92 Mt of lithium carbonate equivalent and 7.68 Mt of boric acid equivalent
- Underpinning plans for a large, long-life, low-cost expandable operation, producing lithium carbonate, boric acid and then battery-grade lithium hydroxide
- Stable co-product - boric acid accounts for an average 25% of annual revenue in the first 25 years; helping ensure positive EBITDA at low lithium prices and EBITDA margin of 65.7% based on average production over first 25 years
- All-in sustaining cash cost of US$5,745 per metric tonne lithium carbonate equivalent places the Rhyolite Ridge Project in the bottom of the global lithium cost curve
- Compelling Project economics with an after-tax NPV of US$1.367 billion, and an unlevered, after-tax internal rate of return (IRR) of 14.5%
The Ore Reserve has increased by 186.6 million tonnes (Mt) and approximately 48% of the Mineral Resource has been converted into Reserve, now estimated at:
- 246.6 Mt at 1,464 ppm lithium and 5,444 ppm boron
- Containing 1.92 Mt of Lithium Carbonate Equivalent (LCE) and 7.68 Mt of Boric Acid Equivalent (BAE)
“Today’s updated Reserve and Mine Plan reinforces the importance of Rhyolite Ridge’s remarkable mineralogy. Our Ore Reserve estimate of 247 Mt containing a total of 1.92 Mt LCE and 7.68 Mt BAE make it the largest lithium-boron Reserve in the world,” said Bernard Rowe, Managing Director, Ioneer. “It allows Ioneer to match prevailing market conditions and blend or prioritise ore to produce a valuable boric acid co- product, whose market is uncorrelated with the Project’s primary lithium product. No other lithium project offers this level of flexibility and economic advantage. In periods of low cycle lithium pricing, like today, we plan to prioritize the high-boron ore production to optimize the relative proportion of total revenue derived from boric acid.”
By prioritising High-Boron (Hi-B) ore in the first 25 years of production, the Project is poised to produce an average of ~19,200 tonnes per annum (tpa) of LCE, and 116,400 tpa of boric acid (see Table 1).
The updated Ore Reserve estimate, 95-year mine plan for stage one operations, and Project economics reaffirms Rhyolite Ridge as a highly attractive global Project to produce lithium carbonate, lithium hydroxide and boric acid. The updated findings position Ioneer, on an LCE basis, in the lowest cost quartile for lithium production globally with an estimated all-in sustaining cash cost to produce battery grade lithium hydroxide of US$5,745 and a cash cost of C1 $3,858 per tonne net of expected boric acid revenue in the first 25 years.
The Project has a stable overall operating cost structure to produce lithium carbonate and battery grade lithium hydroxide due to the scale and reliability of its boric acid credit. Boron remains one of the most stable natural resource commodities over many decades.
Ioneer has refined Project plans over the past four years and updates now include an Association for the Advancement of Cost Engineering (AACE) Class 2 capital cost estimate (-10%, +15%) with approximately 70% of the Project’s engineering complete. As a result of this and other engineering work including RAM analysis and detailed engineering design, Ioneer has adopted a more conservative approach to plant availability, equipment downtime and maintenance strategies. While this approach reduces bottom line economics, the Company believes it is appropriate for a Project of this type and scale.
The Company now estimates total capital expenditure to complete the Project will be US$1,667.9 million, including a 10% contingency.
