Une mine de terres rares va voir le jour au Brésil pour exploiter le dépôt Pela Ema

Serra Verde secures regulatory approval for first phase of rare earth mine in Brazil

Staff Writer | December 22, 2023

Brazil rare earth elements (REE) developer Serra Verde has been awarded an environmental operating licence for the Phase I of its Pela Ema deposit located Minaçú, Goiás state, giving company all necessary regulatory approvals to complete its commissioning process.


Key commissioning milestones will include the start-up of the processing circuit and the dry stack tailings facility as well as connection of the site to the electricity grid, from which it will source 100% renewable electricity.

The plan, according to Serra Verde, is to bring the Phase I mine and processing plant into operation to support the commencement of commercial production by the end of this year.

Once operational, the Pela Ema mine will produce a unique concentrate containing a high value combination of both heavy and light magnetic REEs, including neodymium (Nd), praseodymium (Pr), terbium (Tb) and dysprosium (Dy), all of which are essential to the manufacturing of high-efficiency permanent magnets used in electric vehicle motors and wind turbine generators.

With its ionic clay deposit, Serra Verde said it will use “low operating risk open mining techniques and simple, established processing technologies with no hazardous chemicals, resulting in lower operating costs and superior environmental social and governance credentials.”

“We are thrilled to have received this final licence, which means Serra Verde is on track to become the first scale producer outside Asia to provide all four rare earths essential to the production of efficient permanent magnets, supporting the energy transition,” Serra Verde’s CEO Thras Moraitis commented, adding that its REE deposit “will be a strategic asset in the global permanent magnet value chain for many years to come.”

Phase I of the Pela Ema project is expected to produce at least 5,000 tonnes per year of rare earth oxide over a 25-year mine life, with offtakes already in place for a large proportion of planned production. There is also significant potential to increase capacity through plant optimization, Serra Verde said.

The large, defined resource could facilitate a potential Phase II expansion of the Pela Ema deposit, with the objective of doubling run-of-mine production before the end of this decade, it added.

Serra Verde said that it has started commercial production of mixed rare earth concentrate (MREC) from the first phase of its Pela Ema deposit located in Minaçu, in the Brazilian state of Goiás.

The commissioning process was launched in June 2023.

Upon reaching full production capacity, Serra Verde anticipates an annual output of at least 5,000 tonnes of rare earth oxide. This oxide is crucial in the production of high-efficiency permanent magnets, essential components for electric vehicle motors and wind turbine generators.

According to the Brazilian rare earth elements (REE) developer, Pela Ema is a substantial and enduring ionic clay deposit characterised by a notable concentration of valuable heavy and light REEs. These particularly include neodymium (Nd), praseodymium (Pr), terbium (Tb), and dysprosium (Dy), which are crucial components for facilitating the energy transition.

Serra Verde has reported the acceptance of its MREC samples by significant clients, with confirmed offtakes securing a substantial portion of the planned production through agreements with established processing companies.

The company has initiated efforts to enhance the capacity of Phase I at Pela Ema through plant optimisation. Simultaneously, it is evaluating the feasibility of a Phase II expansion, which could potentially double the run-of-mine production before the year 2030.

Serra Verde indicated its aspirations to become the world’s most sustainable supplier of rare earth materials. This goal is pursued by harnessing the superior sustainability credentials of its operations and adhering to world-class operating standards, claimed the company.

Serra Verde CEO Thras Moraitis said: “The start of commercial production is a critical milestone in our development and means we are now the only company outside Asia to produce at scale all four critical rare earths used in the production of permanent magnets.

“Our product can play a critical role in supporting the growth in production of electric vehicles and wind turbines that are vital to the energy transition.

“As we ramp up to achieve nameplate capacity, Serra Verde is also working to build downstream partnerships to support the development of long-term, sustainable supply chains.”

Rainbow Rare Earths starts rare earth oxide separation in US
The first batch of separated oxides, specifically neodymium and praseodymium, is expected to be delivered in the coming weeks.

January 11, 2024

Rainbow Rare Earths has announced the initiation of the rare earth oxide separation process at K-Technologies’ facilities in Florida.

This development in the Phalaborwa pilot plant process marks a move towards more environmentally friendly extraction methods, utilising continuous ion exchange (CIX) and continuous ion chromatography (CIC) technology.

The CIX/CIC process, pioneered by K-Tech, is now in continuous operation.

It replaces the traditional solvent extraction method, which relies on hazardous chemicals and involves a complex, multi-stage process.

The four critical REEs to be produced at Phalaborwa are neodymium, praseodymium, dysprosium and terbium, all of which are essential for the green economy transition.

These elements are key components in the manufacture of permanent magnets used in EVs and wind turbines.

They also play a crucial role in advanced technologies for strategic defence, such as guided missiles and jet fighter engines. K-Tech’s bench scale testwork has already demonstrated positive results, aligning with expectations for the separation of these rare earth oxides.

The first batch of separated oxides, specifically neodymium and praseodymium, is expected to be delivered in the coming weeks.

Dysprosium and terbium will follow, given their lower volumes in the rare earth mix.

The front-end pilot plant, located at the Council for Mineral Technology’s Johannesburg facilities, has successfully completed two of three campaigns, producing approximately 5.75kg of mixed rare earth carbonate, which has been sent to K-Tech in five batches.

The front-end pilot plant is set to commence continuous operations from mid-January 2024. This integrated campaign aims to increase the production of mixed rare earth carbonate for shipment to K-Tech throughout the first quarter of 2024.

Rainbow Rare Earths CEO George Bennett said: “Whilst we have experienced some delays from the original timetable due firstly to the further beneficiation of the mixed rare earth sulphate to produce a cerium-depleted mixed rare earth carbonate as the optimal feedstock for the K-Tech CIX and CIC circuits, plus two key mechanical issues at K-Tech, which took longer to resolve than anticipated due to the Christmas period, this has in no way affected the integrity of the process flowsheet, which is progressing as planned.

“During this time, we have continued with front-end plant optimisation work in order to deliver the most efficient final flowsheet for commercial operations, as well as ongoing shipments of mixed rare earth carbonate to K-Tech. We look forward to providing updates on the pilot plant milestones during Q1 2024.”

China’s rare earth exports hit 5-year high on demand from EV, high-tech sectors

Reuters | January 12, 2024

China’s exports of rare earths in 2023 rose 7.3% from the prior year, customs data showed on Friday, boosted by competitive prices and growing overseas demand from electric vehicle makers and other high-tech sectors.


The world’s largest producer of rare earths shipped 52,307 metric tons of the minerals abroad last year, the highest since 2018, data from the General Administration of Customs showed.

Demand for rare earths picked up in line with the rapid development of new energy vehicles, wind power and inverter air conditioners, analysts said. The minerals are also used widely in lasers, military equipment and consumer electronics.

China has been engaged in an escalating battle over control of critical minerals and last year introduced restrictions on exports of germanium, gallium and some graphite products, which are used in semiconductors and electric vehicle batteries.

That fanned fears that rare earths might be the next target, spurring a rush of buying.

Europe and the United States are trying to wean themselves from dependence on rare earths from China, which accounts for nearly 90% of global refined output.

The increase in demand, however, lagged a rise in supply, weighing on prices for much of last year, although fears of supply disruptions stoked by a mining suspension in Myanmar pushed prices to a 20-month high last September.

China has set its 2023 rare earth mining quota at 255,000 metric tons and the annual smelting and separation quota at 243,850 tons, both up more than 20% from the year before.

The spot price for praseodymium neodymium oxide at the end of last year was down 34% from a year earlier, at 457,500 yuan a ton, data from consultancy Shanghai Metals Market (SMM) showed.

China’s exports of the 17 minerals classified as rare earths fell 18.2% in December from the previous month, to 3,439 tons, the customs data showed. That was down 20% from December 2022.

China’s imports of rare earths last month were up 45% on the year at 16,381 tons, while the 2023 total climbed 44.8% from a year earlier to 175,853 tons.

La première mine de terres rares d’Ouganda en bonne voie pour entrer en production en 2026

Agence Ecofin 18 janvier 2024

L’approvisionnement en terres rares est un enjeu critique pour de nombreux pays. La demande augmente en raison de la transition énergétique, mais l’offre reste dominée par la Chine. Pour l’Ouganda qui veut accroitre la contribution des Mines à l’économie, c’est l’occasion d’exploiter ses réserves.

Rwenzori Rare Metals, filiale de l’australien Ionic Rare Earths, a reçu le permis d’exploitation minière pour le projet Makuutu qui sera donc d’ici 2026 la première mine de terres rares d’Ouganda. Le document a officiellement été signé par la ministre de l’Énergie et du Développement minéral Ruth Nankabirwa, lors d’une cérémonie à Kampala le 17 janvier.

Selon Ionic, l’octroi de ce permis positionne le projet pour une décision d’investissement finale au cours de l’année 2024, suivie de l’entrée en production de la mine en 2026. Notons qu’il s’agit de la première licence octroyée conformément au nouveau code minier ougandais adopté en 2022 et qui prévoit une participation gratuite de 15 % pour l’État dans les mines à grande échelle.

« L’attribution formelle de la licence minière de Makuutu à Rwenzori permet aux discussions avec des partenaires stratégiques et de la chaîne d’approvisionnement potentiels de passer à l’étape suivante pour amener Makuutu et un nouvel approvisionnement en terres rares magnétiques et lourdes sur le marché », a commenté Tim Harrison, DG d’Ionic.

D’après un rapport publié en 2023 par la firme d’analyse Adamas Intelligence, la demande mondiale d’aimants à base de terres rares (NedFeB) devrait connaitre un taux de croissance annuelle composé de 7,5 % jusqu’en 2030, soutenue par les secteurs des véhicules électriques et de l’énergie éolienne. Cela se traduira par une « croissance comparable de la demande pour les éléments de terres rares critiques », notamment le dysprosium et le terbium, précise le document.

Or, plusieurs de ces métaux critiques concernés se retrouvent dans la future production de Makuutu. Selon l’étude de faisabilité publiée en 2022, le projet peut en effet livrer, sur 35 ans, 40 090 tonnes d’oxyde de terres rares, titrant 71 % de métaux comme le néodyme, praséodyme, dysprosium et terbium. Makuutu est donc bien positionné pour contribuer à satisfaire la demande mondiale croissante pour les terres rares et soutenir la stratégie du gouvernement ougandais d’accroitre la contribution du secteur minier à l’économie.

Le Fonds souverain d’Angola réitère son soutien au développement de la première mine de terres rares du pays

Agence Ecofin 15 janvier 2024

Selon le rapport ITIE 2021, le pétrole représente 40 % des recettes publics en Angola, contre 0,32 % pour les diamants, principale ressource minière exploitée. Pour augmenter la contribution du secteur minier à l’économie, le gouvernement compte sur l’exploitation des terres rares.

Le Conseil d’administration du Fonds souverain angolais (FSDEA) a effectué le 10 janvier une visite de travail sur le site abritant le projet de terres rares Longonjo. Les responsables sont allés constater l’utilisation qui est faite du récent prêt relais de 15 millions de dollars accordé pour financer les travaux menés en prélude à la construction de la première mine de terres rares d’Angola.

« Nous sommes ravis de constater les excellents progrès réalisés sur le site de Longonjo qui est un projet important pour nous. Le FSDEA a financé l’accélération des activités de construction afin de garantir que le projet reste dynamique pendant que nous travaillons avec le consortium de prêteurs pour conclure le financement principal », a déclaré au cours de sa visite Armando Manuel, président du conseil d’administration, dans un communiqué publié le 15 janvier par Pensana.

Pensana est la compagnie minière britannique qui pilote le projet Longonjo. À travers la société ASF Yova Mining, le Fonds souverain angolais est le premier actionnaire de Pensana, avec 26,5 % d’intérêts à la date du 7 décembre 2023. Selon des travaux actualisés et publiés fin octobre 2023, un capital de 200 millions de dollars est nécessaire pour construire la mine, qui pourra livrer annuellement 38 000 tonnes par an de sulfate de terres rares mixtes, dont 4 400 tonnes de néodyme et de praséodyme.

Alors que le secteur extractif angolais reste dominé par l’exploitation du pétrole, ce qui rend l’économie locale très dépendante des fluctuations du prix de l’or noir, le gouvernement angolais mise sur le secteur minier pour accélérer la diversification de l’économie. Outre l’essor d’un secteur diamantifère qui crée de la valeur ajoutée au niveau local, le développement de la première mine de terres rares du pays s’inscrit dans cette stratégie.

L’entrée en production de Longonjo devrait intervenir dans un contexte mondial où la demande de terres rares est en hausse en raison de sa consommation dans diverses industries liées à la transition énergétique (éolienne et véhicules électriques notamment). Alors que la Chine domine le secteur, les États-Unis et les pays d’Europe de l’Ouest cherchent des alternatives et Longonjo est l’une d’elles. La production de la mine sera d’ailleurs transformée dans une usine installée au Royaume-Uni.

Vietnam rare earths output drops as China’s grows, US says

Reuters | February 1, 2024

The US geological agency has sharply revised down estimates on Vietnam’s rare earths output and expects a further drop despite its rich resource base, according to an annual report, which showed a rise in dominant producer China’s output.


The US Geological Survey’s (USGS) estimates, published late in January, came only a few months after Vietnamese authorities arrested in October corporate executives who were partnering with Western companies to develop rare earths mining projects in Vietnam. There is no clear link between the USGS revision and the arrests.

Rare earths are used in multiple industries, including electric vehicles, auto batteries and renewables, and have several applications in electronic and military products.

Despite having the world’s second-largest deposits, estimated at around 22 million tons of rare earths oxide (REO) equivalent, Vietnam extracted only 1,200 tons in 2022, the statistics from the USGS show, down from 4,300 tons the agency had previously estimated for 2022.



Output fell to just 600 tons last year, according to USGS’s new data, despite Vietnam’s plans to boost output to about 20,000-60,000 tons a year by the end of the decade.

The USGS did not immediately reply to a request for comment about its revised estimates. Vietnam does not publish data on its rare earths mining output nor on its trade of the minerals.

While Vietnam’s estimated output fell, the USGS estimated global rare earths mining production grew to 350,000 tons last year from 300,000 tons in 2022, largely due to an increase in China’s output to 240,000 tons from 210,000 tons as Beijing raised its quotas last year.

Myanmar’s production tripled to 38,000 tons in 2023 from 12,000 tons a year earlier.

Hobbled plans?
Before the arrests over allegations of illegal trading, Vietnam was planning new tenders for mining concessions at its largest rare earths mine, which is still largely untapped, Reuters reported in September, citing an executive at Australia’s mining company Blackstone Minerals Ltd.

Blackstone and Vietnam’s environment ministry, which is in charge of mining projects, did not immediately reply to requests for comment about whether the tenders were still planned.

Australian Strategic Materials, another mining company, had also partnered with VTRE in May for the supply of about 100 tons of rare earths oxides by the end of last year. The company did not immediately reply to a request for comment about the state of that deal.

The United States has agreed to boost cooperation on rare earths with Vietnam, whose large untapped resources are seen as an alternative source of the minerals. China has the world’s largest deposits, with 44 million tons estimated, and dominates the extraction and processing of the critical minerals.

The USGS revised down its estimates of US rare earths reserves to 1.8 million tons from 2.3 million previously estimated. It also halved its estimates for Russia’s deposits to 10 million tons from 21 millions.

The US embassy in Hanoi had no immediate comment.

American Rare Earths increases resource estimates for Halleck Creek project

By NS Energy Staff Writer 07 Feb 2024

The in-situ resource estimates increased by 64% to 2.34 billion tonnes at a grade of 3,196ppm total rare earth oxides (TREO), and measured and indicated resource estimates increased by 128% or by 795 million tonnes to 1.42 billion tonnes

Australia-based rare earths supplier American Rare Earths has announced a 64% increase in the rare earth elements resource at its Halleck Creek rare earths project in Wyoming, US.

The company’s announcement is based on a recently completed detailed technical report of exploration and updated resource estimates of the Halleck Creek project.

The JORC 2012-compliant resource estimates were updated based on the results of the September/October 2023 maiden resource estimate, along with additional surface sampling and geological mapping.

The in-situ resource estimates were increased by 64% to 2.34 billion tonnes at a grade of 3,196ppm total rare earth oxides (TREO) using a 1,000ppm TREO cut-off.

The measured and indicated resource estimates increased by 128% or by 795 million tonnes to 1.42 billion tonnes, at a grade of 3,295ppm TREO using a 1,000ppm TREO cut-off.

Also, the inferred resource estimates increased by 15% or 117 million tonnes.

American Rare Earths CEO Donald Swartz said: “These results are illustrative of the enormous potential of the project when the resource increases 64% during a developmental drilling campaign, which increased measured/indicated resources by 128%.

“Typically, you’ll see the resource decrease as infill drilling takes place – instead we’re seeing the opposite, with only 25% of the project being drilled to this point.

“The low-cost mine plan when combined with the breakthroughs around metallurgy has increased our confidence and excitement about this world-class deposit. At 27% MREO, we look forward to releasing the results of the scoping study that is nearing completion.”

American Rare Earths said the encouraging results from September/October 2023 drilling laterally and vertically expanded the geological model for Halleck Creek.

The drilling also provided data to geostatistically define measured resource extents at Overton Mountain and redefine indicated resource extents at Red Mountain.

The Australian rare earths supplier is working together with Stantec, a global engineering consulting provider to develop a JORC scoping study at Halleck Creek.

The partners are evaluating the technical, mining, and economic designs related to the Halleck Creek project, as part of the scoping study.

British Columbia rare earth project testing makes 50% TREO concentrates with 80% recovery

Staff Writer | February 13, 2024

Defense Metals (TSXV: DEFN) says metallurgical testing of samples from its Wicheeda rare earth project in British Columbia has shown that a 50% total rate earth oxide (TRE) concentrate can be made. The recovery rate was 80%. The tests were carried out by SGS Canada.

“Continuing positive results from our technical studies suggest that our wholly-owned Wicheeda REE project has the potential to become the next producer of rare earth elements in North America accounting for a significant amount of the rare earths needed for the western world’s future magnet metal production,” said Defense Metals CEO Craig Taylor in a release.

Beginning in 2018 up to the present, Defense has spent about C$5 million on metallurgical test work and the creation of flowsheets for the Wicheeda project. Recent studies optimized the milling and hydrometallurgical processes and the response of 21 variability samples representing different rare earth element (REE) grades, lithologies and locations within the deposit.

The results of the metallurgical tests will be included in the prefeasibility study due to be completed in the second quarter of 2024, said Taylor, and then work would begin on the feasibility study.

The Wicheeda project has measured and indicated resources that total 34.2 million tonnes grading 2.02% TREO and contain 699,000 tonnes of TREO. The inferred portion is 11.1 million tonnes at 1.02% TREO and contains 113,000 tonnes.
