Ionic Rare Earths
Overview
Rare earth metals are best classified as difficult to discover and extract. In 2019, nearly 60 percent of global annual production (an estimated 132,000 tonnes) came from China, with only 12.2 percent of production coming from the second largest producer, the United States. But, what are rare earth metals? And why are they more important than ever?
Rare earth metals are classified into two categories: light and heavy. Light rare earth elements (LREEs) are commonly available and include lanthanum, cerium, praseodymium, and neodymium. Heavy rare earth elements (HREEs) are more difficult to source (and therefore more expensive), and include samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium, yttrium, and scandium.
Known as the seeds of technology, rare earth metals set to play an ever growing important role in the future of clean energy, as well as serving as a key ingredient in the permanent magnets found in wind turbines and electric vehicles. With such rapid forecast demand looming it’s clear why this segment of the mining industry is attracting attention.
Ionic Rare Earths (ASX:IXR, or “IonicRE”) is an exploration and mining development company that aims to create rare opportunities for investors by operating a low capital operation with a high-margin product. The company currently has a 51 percent ownership (earning up to 60 percent) over the promising rare earth elements Makuutu project located in Uganda. Even though it is the company’s only project, the Makuutu project has a post-tax long-term free cash flow estimate of US$766 million over 11 years. This is expected to grow dramatically in the next 12 months as the company increases the resources to increase the potential life at Makuutu beyond 30 years.
The company is focused on developing its flagship Makuutu Rare Earths Project in Uganda into a significant, long life, high margin, supplier of high-value critical and heavy rare earths. Makuutu is an advanced-stage, ionic adsorption clay (IAC) hosted rare earth element (REE) project highlighted by near-surface mineralisation, significant exploration upside, excellent metallurgical characteristics, and access to tier one infrastructure. The clay-hosted geology at Makuutu is similar to major IAC rare earths projects in southern China, which are responsible for the majority of global supply of low-cost, high value Heavy REOs (>95% originating from IAC). Metallurgical testing at Makuutu has returned excellent recovery rates, which provide multiple avenues for a low-CAPEX process route. Makuutu is well-supported by tier-one existing infrastructure which includes access to major highways, roads, power, water and a professional workforce.
Makuutu will produce a mixed rare earth carbonate (MREC) product, and is planning on developing a standalone refinery to then process the radionuclide MREC product to produce secure and traceable individual rare earths required to supply a growing western demand.
Key investor take-aways:
- The Basket; High content of critical and heavy rare earths (73 percent) required to enable transition to carbon neutrality.
- Low capital development (US$89M); Scalable modular approach means that we can expand the operation from initial capital investment using free cash flows from the project.
- High payability mixed rare earth carbonate (MREC) with no radionuclides.
- Long life; 27 years defined but scope to increase this to be much greater with additional exploration upside pending.
- Investigating standalone heavy rare earth refinery to separate MREC into refined products for marketing to western end users.
Figure 1: Makuutu is quickly being defined as one of the world’s most strategically important rare earth projects.
Figure 2: Granit outcroppings south of the mineralisation trend, with the expansive Makuutu project area in the distant north.
Historically, the majority of rare earth metals have been produced in China. However, economically significant deposits are now being explored and developed all around the world due to the increased commercial interest in the element driven by desires to develop secure supply chains to meet dramatic increases in future demand.
Additionally, Makuutu is the third-largest scandium deposit on the planet with 9,450t+ of scandium available and near term potential for a step change in size.
“We’ve recently done some exploration drilling that indicated that the overall mineralization system of Makutuu is going to get a lot bigger, so we’re going to continue to add value to shareholders and build a very large project,” Tim Harrison said in a recent interview.
Figure 3: Phase 4 infill drilling at Makuutu which is expected to net a significant increase in resources at Makuutu.
Figure 4: Makuutu project location, 120 km east of Kampala, Uganda.
Makuutu may have a strong presence of scandium, but the project also serves as a “one-stop-shop” for many other rare earth elements, especially the high value and high demand magnet rare earths , neodymium, praseodymium, dysprosium and terbium, and many others. There are 16 rare earth elements found in the Makuutu IAC mineralization, with lanthanum oxide, yttrium oxide, and neodymium oxide being found in the highest concentrations. Forecasting the price of all the rare earth elements found at Makuutu is how Ionic Rare Earths is expected to earn US$766 million over 11 years, with much more upside long term given sensitivity analysis indicated a 10% increase in rare earth prices projected a massive 30% increase in NPV post tax.
Ionic Rare Earths is led by a strong corporate management team with decades of applicable experience. Trevor Benson, the chairman, has over 30 years experience with investment banking and stockbroking, focusing on the resources sector. Tim Harrison, managing director, brings 20 years of experience in mineral processing and hydrometallurgy. Max McGarvie, the non-executive director, has 45 years of experience in mining development and mineral processing. Combined, the experienced management team is fully equipped to lead Ionic Rare Earths to success.
Company Highlights
- Ionic Rare Elements is an exploration and mining company that is cultivating a promising basket of rare earth metals, which includes magnet rare earths neodymium, praseodymium, dysprosium and terbium, in high demand to feed the insatiable demand for Evs and offshore wind turbines
- Makuutu’s unique rare earth basket has the full list of all individual REEs required for the future industries dependent upon a secure and stable supply

Sulista Exploration Results Confirm a New High-Grade Rare Earth District
Brazilian Rare Earths Limited (ASX: BRE) (OTCQX: BRELY / OTCQX: BRETF) announces exploration results at the Sulista Project, located ~80km southwest of the Monte Alto project. The exploration program delivered outstanding outcomes across multiple targets, upgrading the Sulista Project to a high-grade rare-earth district.
Sulista Rare Earth District - Leading scale, high-grade and strategic location
- District Scale: New drill results confirm an extensive high-grade rare-earth system at shallow depths - with +7 km of cumulative mineralised strike over seven exploration corridors within the Sulista Rare Earth District in Bahia, Brazil
- Exploration Target: Sulista covers a vast ‘10 km by 2 km’ exploration target area returning shallow, high- grade rare earth mineralisation results across regolith, bedrock and outcrop vectors. Exploration Target has now been estimated across the seven exploration corridors at Sulista
- Infrastructure advantage: The district is in a strategic location, with state highway BR-330 traversing and connecting Sulista with the Camaçari Petrochemical Complex, Bahia; 138 kV power just ~4 km, and skilled workforce and services ~12 km
Sulista East - Outstanding rare earth assays across regolith, bedrock, and new outcrop boulders
- Large-scale, shallow, high-grade rare earth system identified with true thicknesses up to 30 m over 500 m of strike, still open along trend and at depth
- New drill highlights include grades up to 9.6% TREO, with 15,695ppm NdPr, within 16.6 m at 3.9% TREO from surface (STU1482, open at depth), and large intercepts 33 m at 3.8% TREO from 7 m (JITDD0036)
- Widespread mineralised outcrops with grades of up to 10.5% TREO extend Sulista East by +5 km to the south; latest drilling defines a continuous, tabular bedrock rare earth deposit with grades over 3% TREO
- New discovery just ~500 m north of Sulista East: ‘Monte Alto-style’ ultra-high-grade outcrop boulders at 32.1% TREO, provide classic pathfinders to high-grade bedrock mineralisation
Figure 1: Sulista Project: Drill tested deposits and priority drill targets1
Sulista West - Outcrop Ridge drill program targeting high-grade extensions
- New 5,000 m diamond drill program is now underway at Sulista West, targeting a high-grade REE–Nb–Sc– Ta–U system beneath an intense surface geophysical anomaly
- Outcrop Ridge target is anchored by outcrop grades up to 20.6% TREO (R1255) and earlier drilling up to 22.4% TREO, pointing to a second high-grade centre advancing in parallel with Sulista East
- Follow-up auger results with grades up to 15.6% TREO with 34,467ppm NdPr and 1,767ppm DyTb within Sulista West Deposit cover interval of 6 m at 9.9% TREO from 14 m (STU1813)
Sulista District Exploration Target
Exploration Target estimate of 12–18 Mt, with grades of 4–6% TREO, across seven exploration corridors across the Sulista District.
- Observed thickness & grade distribution: At Sulista East ~70% of drill holes intersect mineralisation, with significant intercepts showing cumulative widths of 15–20 m and a length-weighted interquartile range of 3–5% TREO
- District-scale continuity from multiple pathfinders: >1% TREO auger trends, ground/airborne radiometric anomalies, broad gamma anomalies correlated with high-grade secondary monazite, and ultra-high grade outcrops/boulders define a drill-ready strike over ~6 km
- Geological process: Coexistence of a rich, coherent and consistent tabular bedrock REE melt (~3.1% TREO), thick high-grade regolith above, and proximal Monte Alto-style boulders indicates a highly prospective magmatic and regolith system that repeats along strike
The potential quantity and grade of the Exploration Target is conceptual in nature. There has been insufficient exploration to estimate a Mineral Resource, and it is uncertain if further exploration will result in the estimation of a Mineral Resource.
Sulista Drilling Status
- Sulista East: 44 core holes completed (4,737 m); 13 holes assayed and reported herein (1,188 m); 31 holes pending (3,549 m)
- Sulista West: 14 diamond holes previously completed (1,885 m), with assays previously reported for 11 holes (1,463 m) Including up to 22.4% TREO. New 5,000 m drilling program underway at Outcrop Ridge
- Sulista District: 61 new auger holes completed (1,040 m)
Next Steps
- Drilling: Step-out program to extend the Sulista East trend along the >1% TREO corridor; systematic drilling over the Monte Alto-style boulder field; advance Outcrop Ridge and priority targets
- Geophysics: Execute high-resolution helicopter magnetic & radiometric survey
BRE’s Managing Director & CEO, Bernardo da Veiga:
“Our successful exploration pathfinder model continues to deliver at our Sulista Rare Earth District – with the latest results confirming expansive, high-grade rare earth mineralisation with a clear path to scale.
These exceptional results also reinforce our conviction in the Rocha da Rocha Rare Earth Province. We now see the potential for this vast province to hold multi-district high-grade rare earth systems - and we’re at the beginning of systematically unlocking this potential.”

The Waste Debate: Can Rare Earth Elements be Extracted from Coal Ash?
Engineers from Monash University are saying they have found a better way to strengthen critical minerals and rare earths supply in Australia by recycling.
A report by the university claims that coal fly ash (CFA), the powdery waste that comes out of burning brown coal, could be the next best solution to extract critical minerals and rare earth elements (REEs).
“For decades, Australia’s coal-fired power stations have produced millions of tonnes of this ash, most of which ends up in ash dams or landfills…But what if that so-called waste could help power the technologies of the future – and ease the pressure on traditional mining?,” the engineers ask.
Coal fly ash, particularly the kind produced from brown coal in Victoria, was the subject of most experiments, as these are said to not contain radioactive elements like uranium or thorium.
The engineers are calling this solution “urban mining,” saying that it could power the green revolution.
What can urban mining do?
According to the engineers, the method they have discovered can recover all 17 REEs above a 90 percent efficiency rate.
They explained that the absence of radioactive elements makes the extraction process “inherently safer,” with less regulations and more environmentally sustainable compared to traditional rare earth mining.
Highly sought-after “magne” rare earths such as neodymium and dysprosium, which are used for electric motor and wind turbine magnets, are included in the extraction’s produce.
“To give you a sense of the potential, from coal fly ash alone, we could recover up to 45,000 tonnes of rare earth metal each year,” they wrote.
How does it work?
A previously published study by Monash University outlined five materials and methods for extracting REE from coal waste, which is summarised below:
- Sample preparation - collection of brown coal fly ash (BCFA) and separation into containers.
- Total quantification of metals - sending of samples to two external analytical companies, which identified baseline results for major, minor, trace non-REE metals and REEs in BCFA.
- Sequential extraction method - a six-step process reporting a more detailed fractionation capacity, studying modes of occurrence of REEs in CFA.
- Analysis of leachate from the extraction process via ICP-MS, which uses both internal standardization and an additional custom multi-element standard method that ensures accurate quantification
- Assessment of Victorian BCFA via a proposed coefficient, which is “the ratio of the sum of all elements classified as critical by the United States Department of Energy to excessively found REEs”
How is coal waste advancing?
“We’ve already scaled up our process from a small lab setup to a 30-litre system, and we’re now designing a 100-litre semi-continuous unit, with a demonstration plant planned at Monash University,” the engineers shared. “The technology has already won awards, and we’re ready to take the next step.”
The team also said that they are working with industry and government partners to introduce the process to the market, assisting in the clean up of legacy waste from coal-fired power generation.
A previous article published by the Commonwealth Scientific and Industrial Research Organisation (CSIRO) in February 2024 also looked into the transformation of coal waste into REEs, saying that it “ultimately comes down to economics.”
“Do the dollars stack up to recover the minerals from the tailings and overburden or not? If we pre-concentrate, can we then economically recover them?”
The organisation also mentioned that besides the already successful reclamation of coal mining areas for agriculture, coal wastes also holds potential to recover other minerals, such as clay-based minerals, in the future.
It is estimated that more than 71 million tonnes of coal ash is generated globally each year.
Current state of REEs in Australia
Australia is currently emerging as a key player in the global rare earths and even in the critical minerals market, following trade tensions between China and the US.
The country has also been making strategic moves towards rare earths independence, including investment in projects, policy amendments and cross country deals.
Western Australia, in particular, is being put on the global map with its significant rare earths deposits, backed by support from its local government.
“Urban mining gives Australia a chance to lead the world in clean, homegrown rare earth supply while also solving a legacy waste problem,” Monash University concludes. “It could create regional jobs, support local manufacturing, and reduce our reliance on overseas supply chains. It’s a rare opportunity.”

Rare Earths Extracted from Ema ISR Field Trial
ISR leaching confirms commercial scale viability using low concentration MgS04
Brazilian Critical Minerals Limited (ASX: BCM) (“BCM” or the “Company”) is pleased to announce that it has now successfully leached, extracted and precipitated rare earths from its in-situ recovery (ISR) pilot field trial at the Ema project.
Highlights
- First REEs successfully recovered under real-world conditions: Rare earth elements have been leached, extracted, and precipitated directly from the Ema deposit using in-situ recovery (ISR) methods
- Technical viability confirmed: This successful field-based extraction validates the ISR process at Ema and marks a significant step forward for the project’s development
- Environmentally friendly leaching solution used: The REEs were recovered using a low- concentration (0.5M) magnesium sulfate (MgSO₄) solution, supporting BCM’s commitment to environmentally responsible and sustainable mining practices
This achievement strengthens BCM’s position as a leader in low-impact, next-generation rare earths production and demonstrates the potential for ISR to offer a scalable, low-cost, and environmentally superior alternative to conventional mining methods.

Figure 1. Precipitated solids directly in the field after in-situ leaching. Small amounts of reagent added to rare earth rich solution causing the rare earths and impurities to precipitate (cloudy material) in a beaker directly adjacent to extraction wells.
Andrew Reid, Managing Director, commented:
“Our field trials have now conclusively demonstrated that rare earth elements can be successfully leached, recovered, and precipitated from solution via in-situ recovery (ISR) at Ema, exceeding our expectations on all fronts. This represents a major technical and operational milestone and a critical step in de-risking the project.
It confirms that ISR can reliably mobilize and extract rare earths under real-world field conditions, positioning the Ema Project as a transformative development in the global rare earth supply chain— delivering high ESG performance and sustainable extraction practices.”
“We now look ahead to completing the current field trial program, initiating the feasibility study, and progressing key workstreams including permitting, financing, and offtake negotiations.
Ema remains uniquely positioned outside Southeast Asia as the only known rare earth project capable of operating via ISR with exceptionally low capital and operating costs. The February 2025 Scoping Study highlighted Capex of just US$55M and Opex of just US$6.15/kg TREO whilst able to produce 4,800tpa of TREO or 1,800tpa of key magnet elements in a mixed rare earth carbonate product.”

Dalaroo Prepares Maiden Work Program for Blue Lagoon Zirconium, Niobium and Rare Earth Project in Greenland
Dalaroo Metals Ltd (ASX: DAL, “Dalaroo” or “Company”) is pleased to provide an update on planned activities at the Blue Lagoon Project in Greenland.
Highlights
- Dalaroo has advanced planning for upcoming maiden field season at the Blue Lagoon Zr- Nb-REE project, Greenland. Field work will be conducted towards the end of June 2025.
- A program of auger drilling, stream sediment and soil sampling and reconnaissance mapping and sampling has been designed to follow up on historical highly anomalous values returned in a regional stream sediment program undertaken by the Greenland and Denmark Geological Society (‘GEUS”) for uranium in 1979 (refer to ASX release 20th Feb, 2025).
- No follow-up work on these results has ever been reported on the tenement.
- Dalaroo has secured the services of highly respected and experienced Greenland geologist Ole Christiansen, who has been instrumental in the modern development of metals in Greenland, including Critical Metal’s (NASDAQ: CRML Critical Metals Corp) Tanbreez project.
- The Blue Lagoon Project has similar geochemical anomalous footprint to the Kvanefjeld (ASX: ETM Energy Transition Metals) and Kringlerne/Tanbreez multi-element deposits in South Greenland, showing enrichment in critical minerals and high value LREE elements from regional stream sediment sampling. These projects are all hosted within the south- west north-east trending Gadar alkaline intrusive province where Blue Lagoon Is also located.
- US administration has continued to show considerable interest in Greenland, highlighting the importance Greenland has for critical metals and their ownership.
- Auger drilling to sample alluvial and colluvial material will form a key part of the program. In situ weathering of the alkaline granite might provide bulk tonnage options from beach- like deposits, providing potential low-cost options for mining and separation. Characterising these deposits geochemically is the first step of the evaluation of this potential.
Dalaroo Metals MD & CEO, Mike Brown commented “We are excited to have advanced a maiden field program at Blue Lagoon, and also secured the services of renowned Greenland geologist Ole Chistiansen. Auger drilling of weathered granite areas will be a key objective of the program. Stream, soil and rock chip sampling and prospecting over the tenement will complete the program. This should provide the first insight into the potential of the project to host heavy mineral sands type deposits of strategic metals and REEs. Placer deposits have obvious benefits on the cost of mining. With the Project being located on the coast with ice free water we are looking forward to getting onto the ground to commence exploration activities in June and report results when in hand.”
Figure 1: Project location, GEUS regional stream sediment location and neodymium assay results
The large and highly anomalous zirconium, niobium and REE geochemical anomalies over the Project area provides a compelling multi-commodity exploration target. The Vendor has identified the presence of potential bulk tonnage ‘placer’ type deposits from in-situ weathered granite. This is characterised by highly anomalous LREE and Nb signature, which is very similar to the geochemical signature that coincides with 3 other significant REE deposits in South Greenland associated with Gadar Block alkaline intrusives. The Company is looking forward to reporting the results of the work program as they come to hand.
