UPDATED TEST RESULTS 99.9% LITHIUM CARBONATE PURITY
- Globally regarded processing group Veolia Water Technologies produced lithium carbonate samples with 99.9% purity, from the Salar de Maricunga brine
- Optimised evaporation process developed by the Minera Salar Blanco (MSB) Maricunga project team has resulted in impurity removal
- Pilot plant testing to continue to further quantify the process for commercial application.
The optimised evaporation process has been developed by Peter Ehren; Principal Process Consultant to the Maricunga Project (MSc. Raw Materials Technology, MAusIMM CP under JORC and QP under NI43-101) and executed by Veolia. This work has been achieved by using several crystallization techniques to remove primary contaminates such as tachyhydrite and calcium chloride from the concentrated Maricunga lithium bearing brine (Brine).
A second part of the process provides for simplified and optimized polishing stages in order to remove the remaining boron, calcium and magnesium from the concentrated lithium brine. This successful application ensured the purity of the final washed lithium carbonate product was 99.9% which greatly exceeds the battery grade lithium carbonate specification as can observed in the table in link below.
Lithium Power's Chief Executive Officer, Martin Holland said:
"We are exceptionally pleased that our test work has produced such a proven process that can extract and deliver such high purity lithium carbonate product. These exceptional results will be further enhanced and developed to ensure the operational application of these results in the planned mining and processing operation. The LCE purity clearly exceeds battery grade requirements and will continue to generate interest from possible off-take partners."
MSB's Chief Executive Officer, Cristobal Garcia-Huidobro, said:
"The MSB developed optimised evaporation process along with the pilot plant testing conducted by Veolia has produced results which ensures that the Maricunga lithium brine project will be continued to be seen as Chile's most advanced and highest quality pre-production lithium project."

About Lithium Power International Ltd
Lithium Power International Limited (ASX:LPI) (FRA:24L) is a pure-play lithium explorer and developer, focusing on developing and fast-tracking to production the high-grade Maricunga lithium brine project in Chile.
LPI has a well known performing technical team with the experience to take the Maricunga project all the way through the development stages to production.
The regions that LPI is currently focussed on are:
1. Maricunga JV (Chile) – On 13th September 2016, Lithium Power announced the creation of a new JV to develop the world-class Maricunga lithium brine deposit in northern Chile.
2. Pilbara (Western Australia) – LPI has one granted exploration tenement and two pending exploration applications covering 203km2 in the Pilbara region of northern Western Australia. The largest granted exploration tenement is at Pilgangoora-Houston Creek is 2-3km west of the Pilbara Minerals (ASX:PLS) and Altura Mining (ASX:AJM) lithium deposits.
3. Greenbushes (Western Australia) – LPI has two granted exploration tenements covering 400km2 in the Greenbushes area of southern Western Australia. The tenements are adjacent to the world’s largest hard rock lithium mine owned & operated by Tianqi/Talison.
4. Centenario (Argentina) –Through its Argentinian subsidiary, Lithium Power holds a total of 6 granted tenements in the Centenario lithium brine salar within the Salta province of the Puna Plateau. In total, the 6 granted tenements cover an area of 61.52km2. In addition, there is 1 further tenement in the grant review stage.
With the exception of the Maricunga JV, all tenements are 100% owned by LPI or LPSA (including rights to the Centenario tenement which is the subject of review by the Argentinian mining authorities).
