Name of the Project
Longonjo neodymium/praseodymium project.

Location
Huambo, Angola – 4 km from a modern rail line leading directly into the Port of Lobito in the Atlantic Ocean.

Project Owner/s
Pensana Rare Earths holds an 84% interest in Longonjo through its 84% holding in Angola-registered company Ozango Minerais, which, in turn, owns 100% of the mining licence.

The Angolan government holds a 10% interest and the company’s Angolan partners the remaining 6%.

Project Description
Longonjo is one of the biggest rare earths deposits in the world, with an initial 20-year mine life.

The project has total proven and probable reserves of 30.1-million tonnes grading 2.55% neodymium/praseodymium oxide for 166 000 t neodymium/praseodymium and total rare-earth oxides (TREOs) of 767 000 t.

The mine execution plan is based on a staged development of the mine and processing facilities.

At full production, once the phased development is complete, the Longonjo mine will target production of up to 38 000 t/y of mixed rare-earth double sulphate or mixed rare-earth carbonate (MREC) containing 14 000 t of TREOs and up to 4 400 t of neodymium/praseodymium oxides. This equates to about 5% of the worldwide production of neodymium/praseodymium oxides a year for downstream processing or to be sold on the international market.

Initial feedstock will be shipped as a clean, high-purity mixed rare-earth sulphate to Pensana’s Saltend rare earth oxide separation facility, in the UK.

Potential Job Creation
The mine will employ about 650 people during construction and will create 420 permanent, high-value jobs.

Net Present Value/Internal Rate of Return
Not stated.

Capital Expenditure
$217-million for the fully permitted mine and processing facilities.

Planned Start/End Date
Longonjo is expected to produce 20 000 t of MREC starting in 2026 and 40 000 t of MREC from 2029 onwards following the planned expansion.

Latest Developments
Pensana has signed a nonbinding memorandum of understanding (MoU) with Japanese trading group Hanwa for the offtake of up to 20 000 t/y of MREC.  

Hanwa and Pensana will cooperate on marketing and distribution for the MREC globally, as well as to develop a strategic and sustainable supply chain for magnet metal materials.

Hanwa is considering a deeper cooperation with Pensana, including an investment in upstream and downstream projects with the aim of delivering low embedded carbon magnet metal materials to Hanwa’s customers and future partners.

Hanwa will also consider providing financial support and to jointly study support opportunities from governmental and financial institutions for the various projects that Pensana is pursuing.

These include Coola and the Sulima West expansion, which relates to a separation and metallisation project.
