Lynas, the only major proven producer of rare earths outside China, added that Gading Senggara Sdn Bhd has been appointed as the contractor to manage the project for $98 million.

In August last year, Malaysia renewed the operating licence for Lynas' processing plant for six months with new conditions including the identification of a site for a permanent facility to store its low-level radioactive waste.

The Atomic Energy Licensing Board, an agency under the Malaysia's environment ministry, asked Lynas to present a plan to set up a cracking and leaching facility overseas within four years of the licence renewal.

Last week, Lynas said it was on track to get its processing license renewal in March.
