Lithium One Engages Engineering Firm to Complete PEA on Sal de Vida Lithium and Potash Brine Project

Lithium One Inc. (the "Company") (TSX VENTURE:LI), is pleased to announce that
independent engineering firm ARA Worley Parsons ("ARA") has been retained to
complete the NI 43-101 compliant Preliminary Economic Assessment report ("PEA")
for the Sal de Vida Lithium-Potash brine project in Argentina. ARA is a leading
full-service engineering services firm with offices throughout Latin America.
ARA's experience in the sector includes the design and construction of many
components of the world's largest and lowest cost lithium-potash brine
processing facility in Chile. 


The Sal de Vida PEA will model the economics of a conventional evaporation
recovery circuit for lithium and potash. Lithium One has already benefitted from
the guidance and expertise of leading consulting engineers and scientists, such
as:




--  Jerome Lukes - Process Engineer. Helped develop the evaporation recovery
    system at SQM's operations at Salar de Atacama 
--  ACSI - Mechanical Engineering and Metallurgy backgrounds with major cost
    engineering, project management and process development experience on
    base metal and lithium projects 
--  Raul Diaz - Argentina based mechanical engineer with extensive field
    operations experience, including the first development of the Salar de
    Rio Grande sodium sulphate project in Argentina 
--  Hazen Research - A leading metallurgical and testing laboratory with
    experience in solvent extraction with brines at Salar de Atacama 



The engineering and process work completed to date has laid a strong foundation
for the PEA and the feasibility study. The Company has progressed several
aspects of the Sal de Vida project in parallel, including: resource delineation,
pilot plant operation and process refinement, environmental and community
baseline studies and pumping tests. This multi-pronged approach will facilitate
timely delivery of the PEA and related NI 43-101 report, which are both expected
to be completed during the third quarter.


Lithium One CEO, Paul Matysek commented, "We are pleased to be nearing the
completion of our PEA only two years after acquiring the Sal de Vida Project.
Our results to date have been outstanding and we expect a robust economic model
will be delivered by ARA. This work will put us in a position to move rapidly
through the completion of the feasibility study in the first half of 2012 and we
remain on track for our goal of delivering the first lithium and potash products
from Sal de Vida in 2015, when strong growth in the lithium market is forecast."



About Lithium One:

Lithium One Inc. is well positioned to be a next-generation low cost producer of
lithium and potash. The Company has two major projects funded through
feasibility by earn-in partners: the Sal de Vida lithium and potash brine
project in Argentina and the James Bay bulk tonnage spodumene project in Quebec.
The Sal de Vida project is one of the largest and the highest-grade lithium and
potash brine projects in the world, with an NI 43-101 inferred resource(i) of
5.4 M tonnes of Lithium Carbonate equivalent and 21 M tonnes of Potash
equivalent (1,470M m(3) at 695 mg/L Li and 7590 mg/L K). KORES, LG International
and GS Caltex are earning a maximum 30% project equity in Sal de Vida by funding
the feasibility study expected in less than twelve months and providing an
off-take agreement for up to 50% of the lithium production. Galaxy Resources is
earning a maximum 70% project equity in the James Bay Project through an earn-in
agreement that includes delivery of a feasibility study by early 2013. The
Company's strategy is to draw upon its quality team and employ best practice to
develop its projects into leading suppliers of low-cost, high quality lithium
products to the global market. 


ON BEHALF OF THE BOARD OF DIRECTORS,

Paul Matysek, Chief Executive Officer

Scoping Study, Preliminary Economic Assessment or Feasibility Study, securing of
debt for future project construction, purchase of future mine production, the
timing for completion of an NI 43-101 compliant resource and other matters
related to the exploration and development of the Project, are forward-looking
statements. These forward-looking statements are made as of the date of this
document and the Company does not intend, and does not assume any obligation, to
