Australia’s BRE achieves first output at RE pilot plant

Australia-based developer Brazilian Rare Earths (BRE) has produced its first rare earth concentrate at its stage one pilot facility in Camacari, located in Brazil's northeastern Bahia state.

BRE produced the concentrate at the newly commissioned the beneficiation circuit of its refinery using feedstock from its planned Monte Alto mine in Bahia, which it is still developing, the company said on 8 September.

The company plans to commission its stage two hydrometallurgical plant by April-June 2027 to produce separated neodymium-praseodymium (NdPr) oxide, as well as heavy rare earth concentrate and uranium yellowcake. BRE will also use the plant to test the recovery of scandium, niobium, titanium, and tantalum as potential co-products.

The company has secured 6.4mn Brazilian reals ($1.25mn) in funding for the stage two plant from the Brazilian national industrial research hub Senai Cimatec, which will cover 59pc of the project's capital and operational expenditure.

The company will also receive technical and engineering support for the pilot plant from French rare earth refiner Carester, who is BRE's heavy rare earth offtake partner. BRE and Carester in October 2025 signed a 10-year offtake deal for heavy rare earth concentrate sufficient for Carester to produce 150 t/yr of separated dysprosium and terbium oxide at its Caremag refinery in Lacq, France.

BRE released an integrated scoping study for both the Monte Alto mine and the Camacari refinery in August. The study plans for first production in 2031 and outlines average production over a 14-year mine life of 5,276 t/yr of NdPr oxide and 2,253 t/yr of heavy rare earth concentrate, containing dysprosium, terbium, samarium, gadolinium, and yttrium (see table).

The company is now undertaking a pre-feasibility study (PFS) for Monte Alto.

Separately, the company is continuing exploration at its Sulista rare earths project in Bahia. Sulista was not included in the scoping study or ongoing PFS.
