Lithium One Signs MOU with Emerging Lithium Producer Galaxy Resources to Form Joint Venture at James Bay Lithium Project Highlights- Galaxy is a producer of lithium in concentrate, with planned lithium carbonate production in 2011- The James Bay depo

VANCOUVER, CANADA -- (Marketwire) -- 12/09/10 -- Lithium One Inc. (the 'Company') (TSX VENTURE: LI), is pleased to report that it has signed a Memorandum of Understanding ('MOU') with Galaxy Resources Limited (ASX: GXY) of Australia ('Galaxy'), under which Galaxy can acquire up to 70% of the James Bay lithium pegmatite project in Quebec through an earn-in and joint venture agreement ('the Definitive Agreement'). Subject to the necessary approvals, the Company expects to close this transaction with a Definitive Agreement before Dec 24, 2010.

Under the terms agreed in the MOU, Galaxy will initially acquire 20% of the James Bay Project for a cash payment of C$3 million. Galaxy may earn up to 70% through the completion of a Definitive Feasibility Study ('DFS') within a 24 month period, including a committed investment of at least C$3 million in the next 12 months.

Lithium One President and CEO Patrick Highsmith remarked on the benefits of the agreement: 'Lithium One is pleased to be working with one of the world's most aggressive developers of hard rock lithium assets. Having recently commissioned their Mt. Cattlin Mine in Western Australia, Galaxy has demonstrated its ability to develop a hard rock lithium deposit and successfully market the production. This agreement with Galaxy brings hard rock experience together with strong connections in the lithium marketplace to fast track the development of the James Bay project, while Lithium One continues to develop the core Sal de Vida lithium brine project in Argentina. Entering into this arrangement with Galaxy also means that both the Sal de Vida and the James Bay projects are now funded through to completion of feasibility by our joint venture partners.'

As part of the feasibility study to be undertaken, Galaxy will evaluate the most suitable location for a battery grade lithium carbonate plant either in Quebec or in Jiangsu, China, where its first lithium carbonate plant is currently under construction. The James Bay project has similar geology and physical characteristics to Mt. Cattlin, so the proposed operational scale and process designs are expected to be similar, which should assist with fast tracking the feasibility study.

Galaxy Resources Managing Director, Iggy Tan, commented on the similarities and synergies of the James Bay and Mt. Cattlin projects: 'Galaxy expects to be able to fast track the development of this project by using the same capacity and design of the plants constructed at Mt Cattlin and Jiangsu. Preliminary test work shows that the James Bay spodumene is comparable in its coarse particle size to the Mt Cattlin ore. This lends itself to similar processing and upgrading methods to those adopted at Mt Cattlin, where simple crushing and heavy media separation are used to produce a 6% lithium oxide spodumene product.'

The James Bay Project is a significant lithium resource in northwestern Quebec. Lithium One announced a NI 43-101 compliant mineral resource last month (see Company news release dated November 18, 2010). Applying a 0.75% lithium oxide cutoff grade, the mineral resource includes 11.75 million tonnes at 1.30% lithium oxide in the indicated category, and 10.47 million tonnes at 1.20% lithium oxide in the inferred category. The resource was described by SRK as likely amenable to open pit extraction and as having potential for an increase in both tonnes and grade with further drilling.

Subject to approvals and execution of the Definitive Agreement, the key parameters of the proposed transaction are:

--  Initial acquisition of 20% of the James Bay lithium pegmatite project
    for a C$3 million cash payment;

--  Upon Galaxy fulfilling its obligation to spend a minimum of C$3 million
    within a 12 month period towards the DFS, Galaxy will earn a further
    31%, increasing its ownership to 51% of the James Bay project;

--  Once Galaxy completes a DFS, within a maximum 24 month period from
    execution of the Definitive Agreement, Galaxy will earn a further 19%,
    increasing its ownership to 70% of the James Bay project;

--  The DFS will include metallurgical test work, engineering design,
    capital and operating cost estimation for a mine and concentrating plant
    at the James Bay project location;

--  In addition, the DFS will include lithium carbonate conversion test
    work, design and costing of a 17,000 tpa battery grade lithium carbonate
    plant in either Quebec, Canada, or near the Jiangsu lithium carbonate
    plant in China, which is currently under development.

--  On completion of the DFS, both parties will be responsible for their
    respective equity interests of the project capital costs;

--  If Galaxy earns at least a 51% interest, Galaxy will have 100% exclusive
    marketing rights for all products from any future operation at James Bay
    except for any sales concluded with parties with whom Lithium One has
    already commenced discussions.

The transactions contemplated by the MOU are subject to customary conditions including, without limitation, the execution of the Definitive Agreement and the approval of the TSX Venture Exchange. The date for the completion of the Definitive Agreement for the transaction is expected to be December 24, 2010; however, there is no certainty that the parties will be able to successfully negotiate the Definitive Agreement or complete the transaction.

About Galaxy:

Galaxy Resources is a Western Australian S&P / ASX 300 Index company which plans to become one of the world's leading producers of lithium compounds. Galaxy wholly-owns and operates the Mt. Cattlin mine in Western Australia, which was recently commissioned and is currently producing spodumene concentrate. Galaxy's Jiangsu lithium carbonate plant, once completed, will have a design capacity of 17,000 tpa of lithium carbonate, which Galaxy expects would make it one of the largest plants in China converting hard rock lithium mineral concentrates into lithium products. Lithium compounds such as lithium carbonate are forecast to be in short supply against high future demand due to advances in long life batteries and sophisticated electronics including mobile phones and computers. Galaxy Resources has positioned itself to meet this lithium future by not only mining the lithium, but also by downstream processing to supply lithium carbonate to the expanding Asian market. Galaxy currently has a market cap of approximately AUS$280M and is a significant component of the Global X Lithium ETF, representing almost 3% of the fund's holdings.

About Lithium One:

Lithium One Inc. is a Canadian-based explorer and developer of mineral properties with a specific focus on lithium. Once the Definitive Agreement contemplated by this MOU is executed, the Company will have two major lithium projects funded through feasibility by earn-in partners: the brownfields Sal de Vida lithium brine project in Argentina partnered with KORES, LG International and GS Caltex; and the James Bay bulk tonnage spodumene project in Quebec partnered with Galaxy Resources. The Sal de Vida option agreement also includes a provision for a project completion guarantee in regards to financing and an off-take agreement for up to 50% of the lithium production.

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 battery market. Lithium One is also a founding member of the Global X Lithium ETF and currently represents nearly 1% of the fund holdings.
