Name of the Project
Longonjo neodymium/praseodymium project.
Location
Huambo, Angola – 4 km from a modern rail line leading directly into the Atlantic Ocean Port of Lobito.
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 hold 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 at 0.55% neodymium/praseodymium oxide for 166 000 t neodymium/praseodymium and total rare-earth oxide (TREO) 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, containing 14 000 t of TREO and up to 4 400 t of neodymium/praseodymium oxide, equating to about 5% of the worldwide production of neodymium/praseodymium oxides a year for downstream processing or to be sold on the international market.
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
