Neometals is planning to capitalise on growth in the energy storage market by commercialising its proprietary process for producing high purity LiOH. The process route shows potential to operate at lowest quartile costs for LiOH.


The ELi Process has been jointly developed by Neometals (70%) and Mineral Resources (30%).

The ELi Process route shows potential to operate at lowest quartile costs for LiOH.

A Pre-feasibility Study was completed in September 2012. Results were as follows:

Input: 147,000t of 6.0% Li2O
Output: 10,000t of Battery Grade LiOH, and
8,810t of Battery Grade Li2CO3
Cost: US$83m (located in Malaysia)
NPV: US$321m using 12% discount rate
OPEX: LiOH US$3800/t - Li2CO3 US$4500/t
IRR: 94%
Payback: ~2 years

The Plan Forward

  • Definitive Feasibility Study due for completion mid-2016.
  • Obtain strategic partner to operate Li downstream plant.
  • Become an independently financed lithium producer.

  • Quarterly Activities Report

    All downstream lithium processing technology and patents are owned by Reed Advanced Materials Pty Ltd (“RAM”). RAM is beneficially owned 70:30 by the Company and MIN.  

    The commercialisation program of the JV Partners patented ELi process will continue separately from arrangements under the aforementioned MOU with primary focus on its application to traditional salar brines as well as spodumene/hard rock supply sources.  

    RAM is in discussions with potential users regarding sub‐licensing the ELi Process to produce lithium hydroxide.
