Ironveld plc (LSE:IRON) has reported rare earth and phosphate mineralisation at its Layer 21 prospect in South Africa, with independent analysis identifying total rare earth oxide grades of between 858 and 1,543 parts per million.
The mining development company said neodymium and praseodymium oxides accounted for approximately 25% of the total rare earth oxides identified in the samples.
The findings follow mineralogical and geochemical analysis undertaken by Mintek, South Africa’s national mineral research organisation, and provide a basis for further evaluation of potential magnetite, ilmenite, phosphate and rare earth recovery.
Separately, Ironveld reported that throughput at its dense media separation (DMS) magnetite plant has increased to approximately 4.5 tonnes per hour, equivalent to 90% of its design capacity.
The company is progressing discussions with prospective customers, although delays to contracted deliveries and new supply agreements have affected working capital. Ironveld said it currently has sufficient working capital for approximately two months and is evaluating external funding options.
Layer 21 Exploration Identifies Rare Earth and Phosphate Mineralisation
Ironveld reported results from two boreholes previously drilled into Layer 21, a magnetite-bearing geological horizon within its mining rights in South Africa’s Bushveld Igneous Complex.
The boreholes were drilled to depths of approximately 100 metres and are located around two kilometres apart.
Mintek conducted mineralogical and geochemical analysis of the recovered core samples.
The results confirmed the presence of vanadiferous titaniferous magnetite, titanomagnetite, ilmenite and apatite.
Several samples were also analysed for rare earth elements, returning total rare earth oxide grades ranging from 858 to 1,543 parts per million.
Neodymium and praseodymium oxides represented approximately one-quarter of the total rare earth oxide content in the samples.
These elements are used in permanent magnets and other industrial applications.
The findings establish the presence of rare earth mineralisation in the sampled material, although further work is required to determine its distribution, recoverability and commercial potential.
Borehole Results Show Iron, Titanium and Phosphate Content
Geochemical analysis identified mineralised intersections in both boreholes.
Borehole HWI45 returned a 15-metre intersection beginning at a depth of 55.5 metres.
The interval contained 48.74% iron oxide (Fe2O3), 8.11% titanium dioxide (TiO2) and 6.35% phosphorus pentoxide (P2O5).
Borehole HWI46 returned a 23-metre intersection beginning at 29.5 metres.
This interval contained 45.82% iron oxide, 7.47% titanium dioxide and 5.83% phosphorus pentoxide.
Ironveld said the phosphate content was associated with the presence of apatite, a phosphate-bearing mineral.
The company also identified a correlation between phosphate and total rare earth oxide grades across the analysed samples.
This relationship suggests that the rare earth mineralisation may be associated with apatite.
Further mineralogical and metallurgical studies will be required to establish the distribution of the rare earth elements and whether they can be recovered through an economically viable processing route.
Conceptual Mineralised Tonnage Estimated at 200 Million Tonnes
Ironveld said its internal assessment indicates a conceptual mineralised tonnage target of approximately 200 million tonnes at Layer 21.
The estimate relates to the potential scale of the geological horizon across the company’s mining rights.
However, the company emphasised that the figure is conceptual and does not represent a defined Mineral Resource or Mineral Reserve.
Additional exploration will be required to establish the extent, continuity and grade of the mineralisation.
Ironveld has not yet determined whether the available geological information will support the definition of a formal Mineral Resource.
The company intends to undertake further geological assessment to establish an exploration programme and identify the work required to define an Exploration Target.
A subsequent Mineral Resource estimate would depend on the results of additional exploration and technical evaluation.
Mineralogy Supports Evaluation of Multiple Products
The Layer 21 mineralogical results indicate the potential to produce several mineral concentrates from the same mined material.
Ironveld is evaluating the recovery of DMS-grade magnetite, ilmenite and apatite.
Magnetite is used in dense media separation processes, including coal preparation, while ilmenite is a source of titanium used in pigment production and other industrial applications.
Apatite is a phosphate-bearing mineral used as a potential feedstock for fertiliser production.
The company is also examining whether rare earth elements could be recovered from an apatite concentrate through additional processing.
Ironveld said the relatively coarse grain size of the identified minerals may support their separation using established mineral processing technologies.
However, the suitability of these methods for Layer 21 remains subject to testing.
The company has not established recovery rates, commercial concentrate specifications or processing costs.
Three-Stage Mineral Processing Flowsheet Under Evaluation
Ironveld has outlined a conceptual processing flowsheet for the Layer 21 material.
The proposed first stage involves multistage milling and low-intensity magnetic separation to recover a DMS-grade magnetite product.
This stage would build on the company’s existing experience in magnetite processing.
A second stage would use wet high-intensity magnetic separation to target the recovery of an ilmenite concentrate.
The third stage would involve flotation to produce an apatite concentrate.
Ironveld said all three methods are established mineral separation technologies, but their performance on Layer 21 material must be confirmed through metallurgical testing.
Any subsequent recovery of rare earth elements from the apatite concentrate would require a separate downstream processing route.
The company intends to evaluate potential processing technologies, commercial partners and recovery options as part of the next phase of work.
Rare Earth Recovery Remains Subject to Further Testing
Ironveld identified neodymium and praseodymium as components of the Layer 21 rare earth mineralisation.
Together, their oxides represented approximately 25% of the total rare earth oxide content in the samples analysed.
The company said this composition provides an additional area for technical evaluation alongside the potential production of magnetite, ilmenite and phosphate concentrates.
However, the presence of rare earth elements does not establish that they can be recovered commercially.
Further testing will be required to assess mineral liberation, processing efficiency, recovery rates and the quality of any resulting concentrates.
Ironveld also intends to investigate downstream processing requirements and potential commercial arrangements for rare earth recovery.
No rare earth production forecast, capital expenditure estimate or development timetable has been announced.
Layer 21 Phosphate Grades Compared With Phalaborwa Deposits
Ironveld noted that the phosphate grades identified in its Layer 21 drill intersections are of a similar order of magnitude to grades reported for Foskor’s Phalaborwa deposits in its 2024 Integrated Annual Report.
The company also referred to Rainbow Rare Earths’ project to recover rare earth elements from historic phosphogypsum tailings at Phalaborwa.
These comparisons provide regional context for phosphate and rare earth mineralisation in South Africa.
However, Ironveld cautioned that differences in mineralogy, processing history and feed characteristics mean that equivalent recovery rates or project economics cannot be assumed.
The company will need to establish the technical characteristics of Layer 21 independently through additional exploration and metallurgical studies.
The results have been reviewed by Ironveld’s Technical Director and independently assessed by an external geologist with experience in rare earth mineralisation.
Layer 21 Development Could Include Multiple Mineral Concentrates
Ironveld’s preliminary development concept involves producing several saleable mineral concentrates from a common mining and processing operation.
The company is examining whether magnetite, ilmenite and apatite production could support multiple revenue streams.
Potential rare earth recovery would represent an additional processing opportunity if technically and commercially feasible.
The company said producing several mineral products from the same material could allow mining and shared processing costs to be distributed across different products.
However, the commercial viability of this approach remains unproven.
The development case will depend on resource definition, metallurgical performance, product quality, capital expenditure, operating costs and market demand.
Ironveld has not announced a development decision or completed an economic assessment of Layer 21.
DMS Plant Throughput Increases to 4.5 Tonnes Per Hour
Separately, Ironveld reported progress at its existing DMS magnetite operation.
Plant feed throughput is currently reaching approximately 4.5 tonnes per hour, compared with the 2.5 to 3.5 tonnes per hour reported in July 2026.
The latest rate represents approximately 90% of the plant’s design throughput of five tonnes per hour.
Ironveld said its immediate operational priorities include improving mill stability, achieving consistent design throughput and maintaining product quality.
The company continues to adjust processing parameters to improve the particle size distribution of its DMS-grade magnetite.
Although the plant has reached higher throughput rates, consistent operation at its design capacity has not yet been established.
Product Size Consistency Remains an Operational Priority
Ironveld said it is continuing to optimise the particle size distribution of its magnetite product.
Particle size is an important specification for magnetite used in dense media separation, particularly in coal processing.
The company is assessing changes to feed size, grinding media size and throughput to achieve the required product characteristics.
Reducing feed and grinding media sizes may improve the final particle size distribution.
Alternatively, lowering throughput may be necessary to achieve the desired specifications.
Ironveld said the particle size distribution is not yet fully consistent across production batches.
Testing is continuing to determine the appropriate balance between throughput, product quality and achievable selling prices.
The company aims to improve production uniformity while maintaining progress towards the plant’s design capacity.
Coal Producers Provide Positive Technical Feedback
Ironveld reported that samples supplied to major international coal producers met their respective particle size distribution acceptance ranges.
The company said the feedback supports the suitability of the tested material for its intended DMS applications.
However, further work is required to ensure consistent production quality and complete customer qualification procedures.
Technical acceptance of samples does not automatically result in a binding supply agreement.
Ironveld is continuing to engage with prospective customers while refining plant performance.
The company has not disclosed the identities of the coal producers providing technical feedback or the potential value of future contracts.
Discussions Progress With Three Prospective Customers
Ironveld reported that discussions with three prospective counterparties are progressing towards potential supply agreements.
The company is pursuing commercial opportunities in Southern Africa and international markets.
The discussions follow product testing and technical evaluation by prospective customers.
Ironveld said the engagements could lead to recurring sales and longer-term supply arrangements.
However, commercial terms have not yet been finalised, and the prospective agreements remain subject to negotiation and execution.
The company has not disclosed expected contract values, annual volumes or delivery schedules.
Ironveld emphasised that technical feedback, sample requests and expressions of interest do not constitute binding purchase commitments.
Prospective Customer Indicates Intention to Order 100 Tonnes
Ironveld also reported that an additional customer has confirmed its intention to place an order for 100 tonnes of magnetite for bulk testing.
The formal purchase order and payment remain outstanding.
The proposed order would allow the customer to undertake further evaluation of the product under larger-scale operating conditions.
The company has not disclosed the proposed selling price or expected delivery date.
Further sample activity is also underway with a prospective South African coal producer and a large coal producer operating in Mozambique.
These engagements form part of Ironveld’s efforts to develop a broader customer base for its DMS magnetite products.
Existing Supply Contract Deliveries Temporarily Suspended
Ironveld confirmed that deliveries under an existing supply agreement are temporarily on hold.
The interruption follows technical difficulties encountered by the customer during the commissioning of its processing plant.
The company said its plant operator is stockpiling material allocated to the customer while awaiting the resumption of deliveries.
The timing of future shipments depends on the customer’s progress in completing commissioning activities.
Ironveld has not provided a date for deliveries to resume.
The company continues to monitor the situation and expects to provide further updates as appropriate.
Working Capital Covers Approximately Two Months
Ironveld disclosed that its current working capital position has been affected by the interruption to existing contracted sales and slower-than-anticipated progress in securing new commercial supply agreements.
Although the company has accumulated a material stockpile of DMS-grade magnetite, the temporary suspension of deliveries has delayed the conversion of production into sales receipts.
The board confirmed that Ironveld has sufficient working capital to meet its operational and strategic requirements for approximately two months.
The company is evaluating several external funding solutions that it described as well advanced.
Ironveld also reported receiving indications from certain existing shareholders that additional funding may be available.
However, no completed financing agreement, committed funding amount or timetable was disclosed.
The company’s near-term financial position therefore remains dependent on securing additional funding, generating sales receipts or other measures before its current working capital is exhausted.
DMS Plant Revenue Intended to Support Layer 21 Development
Ironveld expects to finance the next stages of work at Layer 21 through revenue generated by its existing DMS magnetite operation, which is managed by Daemaneng.
The planned activities include metallurgical testing, further geological assessment and economic evaluation of potential mineral concentrates.
The company also intends to investigate downstream processing options and potential partners for rare earth recovery.
This funding approach depends on the DMS operation generating sufficient revenue to support both its existing activities and additional development expenditure.
The temporary interruption to contracted deliveries and delays in new supply agreements have affected working capital availability.
Ironveld has not provided a budget for the proposed Layer 21 work or specified when the next exploration programme will begin.
CEO Kris Andersson Comments on Discovery and Operations
Kris Andersson, Chief Executive Officer of Ironveld, commented on the Layer 21 findings and the company’s operational progress.
“The rare earths and Phosphate discovery at Layer 21 adds an important new dimension to Ironveld’s asset base. The results provide a basis to evaluate several potential products from the same mineralised horizon, with the neodymium and praseodymium content adding further interest. Our next task is to establish how effectively these minerals can be recovered and whether the opportunity can translate into a commercially attractive development.
“At our DMS operation, throughput is now reaching approximately 90% of design capacity. We still have work to do to achieve consistent performance, but the positive technical feedback from major coal producers is an encouraging endorsement of the material tested.
“Commercially, we are progressing discussions with several prospective customers towards supply agreements, alongside further order and sample activity. This creates an opportunity to build a broader base of recurring business. Our immediate priorities are to convert that interest into contracted sales, resume deliveries to our existing customer when its plant is ready and improve production consistency.
“Together, these developments strengthen Ironveld’s opportunity to grow its magnetite business while assessing the wider value of Layer 21. We look forward to reporting further progress as commercial agreements and technical work advance.
Next Steps for Layer 21 and DMS Operations
Ironveld plans to begin further technical evaluation of Layer 21 in the near term.
The programme will include metallurgical testing to assess mineral recoveries, concentrate specifications and the suitability of the proposed processing flowsheet.
Additional geological work will examine the extent and continuity of mineralisation and determine the requirements for establishing an Exploration Target and potentially a Mineral Resource.
The company will also evaluate the economics of producing magnetite, ilmenite and apatite concentrates.
Separate studies will examine potential rare earth recovery from apatite and the commercial arrangements required for downstream processing.
At the DMS operation, Ironveld intends to improve mill stability, achieve consistent throughput and refine product specifications.
Commercial priorities include converting prospective customer discussions into binding supply agreements and resuming deliveries under its existing contract.
The company is also seeking additional funding to support its near-term working capital requirements.
