Pensana engages Wood Group for UK rare earth processing facility study

Pensana Rare Earths says it has appointed the Wood Group to undertake a study into the establishment of an integrated rare earth processing facility in the UK with a view to creating the world’s first sustainable magnet metal supply chain.

Having progressed the design of the Longonjo rare earths project, in Angola (pictured), to include the production of a mixed rare earth carbonate, Pensana says it now has a unique opportunity to explore the potential for it to make one further step downstream and to create additional value by establishing a rare earth oxide production facility in the UK.

“By linking a mid-stream magnet metal supply with downstream magnet manufacturing capacity there is the potential to create a sustainable magnet metal supply chain at a time of increasing concern over the provenance of these critical metals for the electric vehicle (EV) and offshore wind turbine industries,” the company said.

Following the recent resource upgrade, the Longonjo project is now one of the world’s largest known rare earth resources, according to Pensana.

“To give a sense of scale, the Longonjo project could, together with the UK processing facility, produce enough rare earth oxide to supply the wind turbines at Dogger Bank, projected to be the world’s biggest wind farm, for the next 20 years,” the company said.

With Angola Presidential approval and ongoing financial backing from the Angolan Sovereign Wealth Fund, Pensana’s Longonjo project is well-placed to become the first producing major rare-earth mine in over a decade at a time of burgeoning demand for these critical metals, the company says.

The project is being developed to international standards, has established infrastructure, including the capacity to be entirely powered by hydro-electricity, making Longonjo one of the world’s most sustainable rare earth producers.

Just last week, Pensana announced that Wood and Nagrom, based on test work performed at metallurgical laboratories in Perth, Western Australia, had developed a flowsheet to produce a particularly high-grade MREC, with NdPr comprising 33.5% of the total rare earths content.

Thierry Breton, the EU’s Internal Market Commissioner, recently announced the establishment of a European Raw Materials Alliance recognising that the EU needs to establish sustainable supply and processing capacity of rare earths to support the UK government’s plans for the UK to become the Saudi Arabia of wind, Pensana said.

“Pensana is focused on this broader context and the Wood Group study will take into account sustainable development when considering the process route, preferred location, capital and operating costs, financing arrangements and government incentives relating to the UK project,” it said.

The study is currently expected to take approximately three months to complete.

Pensana Chairman, Paul Atherley, said: “The Wood Group study will look at the first and most important step in creating a sustainable mine to magnet supply chain and that is establishing rare earth processing capability in the UK.”

Pensana Rare Earths says it has successfully produced a neodymium- and praseodymium-rich mixed rare earth carbonate (MREC) from test work currently underway on mineralisation from its Longonjo rare earth project, in Angola.

Industry experts Wood Group and Nagrom, based on test work performed at metallurgical laboratories in Perth, Western Australia, have successfully developed a flowsheet to produce a particularly high-grade MREC, with NdPr comprising 33.5% of the total rare earths content, Pensana said.

This MREC is a much higher-purity and higher-value product and has a much broader market and range of applications than the concentrate product contemplated in Pensana’s prefeasibility study, according to the company. Also, based on information provided by Wood and Nagrom, the specifications of Longonjo’s MREC compare favourably with the main products currently being produced and sold mainly in China.

In the meantime, the pilot plant and metallurgical test work at Longonjo are ongoing with a view to finalising the preferred process route and to providing data for engineering and production cost estimations for the bankable feasibility study (BFS).

A comprehensive update on the BFS will be reported towards the end of the month, with the company explaining that two of the circuits will be required to run for longer to bring the test work results up to the required reporting standards for the study.

“A key feature that the study will report is the potential for the project to be brought online as the first major rare earth mine in over a decade which can also offer a sustainable supply of mixed rare earth carbonate at a time when there is growing concern around the provenance of the rare earth supply chain,” the company said.

Pensana Chief Executive Officer, Tim George, said: “This is an important milestone for the project as it confirms the potential to produce a marketable higher value NdPr rich mixed rare earth carbonate. The market for this carbonate is substantially larger than that of a concentrate and is potentially not limited to China.

“We are now in a position to commence discussions with potential offtake parties in Japan, Korea and Europe in addition to the wide range of potential customers in China.

“Importantly the combination of this value-adding step, with the excellent infrastructure, not least the available hydro-electric power supply, will enable us to develop Longonjo as one of the world’s most sustainable rare earth suppliers on the critical magnet metal supply chain.”

Pensana recently issued a resource upgrade for Longonjo, which outlined measured, indicated and inferred resources of 313 Mt at 1.43% rare earth oxides, including 0.32% NdPr for 4.47 Mt of REO including 990,000 t of NdPr.
