Energizer Resources Inc. (formerly Uranium Star Corp.)  (TSX.V: EGZ) (OTCBB:URST) (FRANKFURT:YE5) (“Energizer” or “the Company”) is pleased to report that the XRF results from the latest completed drill holes indicate that the Company continues to expand the resource on its 100%-owned Green Giant Vanadium Project in Madagascar.

During this phase of drilling, a total of 3,869 metres have been completed to date, bringing the total metres drilled on the property to 16,873 metres. This 2010 drill program will also include a number of step-out drill holes along the main vanadium trend to verify additional mineralized zones previously identified through trenching.

Manga Zone Continues to Expand

The Company continues to expand the Manga zone, which is located in the central part of the main 21-kilometres vanadium trend.  Initial XRF results obtained from recently completed drill holes confirm continued vanadium mineralization in this zone.

The following are highlights of drill hole XRF readings. A complete table summarizing the XRF vanadium mineralization at a cut-off grade of 0.5% vanadium pentoxide ( V₂O₅ ) intersected during this stage of drilling follows at the end of this news release.

• Hole MM-01 intersected 1.00% V₂O₅ over 55.5 metres
• Hole M-56 intersected 0.99% V₂O₅ over 18 metres
• Hole M-57 intersected 0.83% V₂O₅ over 12 metres
• Hole M-58 intersected 0.79% V₂O₅ over 19.5 metres
• Hole M-71 intersected 0.76% V₂O₅ over 40.5 metres

The Company continues to use Niton XL3t hand-held XRF instrumentation to gather readings on core samples with respect to vanadium content, as well as other elements. The Company cautions that XRF readings are not certifiable or recognized in any National Instrument 43-101 compliant resource calculation and variability can be seen when compared with subsequent assays from a registered laboratory.  However, the Company has gained ample experience with XRF technology and expects that frequent calibration to registered standards have enabled it to obtain XRF readings which have a strong correlation to corresponding assay results.

Related drill core samples are being sent to Genalysis Laboratory Services for assaying and the Company looks forward to reporting the drill assay results as they become available.  The Company will continue to report on XRF vanadium mineralization results from the field as they become available.

Current Phase of Drilling to Target 55 Million Tonne Resource

The Company’s target for the 2010 exploration program currently underway is to delineate 55 million tonnes of V₂O₅ .  Based on the Company’s internal assumptions, which will be verified in a forthcoming preliminary economic assessment, 55 million tonnes is expected to represent a 20-year mine life.  Based on these internal assumptions, the Green Giant mine is expected to produce an annual output of 14,700 tonnes of V₂O₅ per year, which would represent 14% of the world’s current annual output of V₂O₅ .

Vanadium…There Just Isn’t Enough

Vanadium has a two-sided growth story – steady demand from traditional steel applications and potentially exponential demand from emerging battery storage applications.

Energizer’s Green Giant project is being positioned to meet not only the 6% year-over-year increase in demand forecasted from the steel industry alone, but also the new demand expected from emerging battery storage applications.

According to Byron Capital Markets’ November 2009 Vanadium Report (the “Report”), companies such as Japan’s Subaru, China’s BYD Auto and the U.S,’s Valence Technology are developing and in some cases, will soon be producing vanadium-based batteries for electric vehicles. The same Report also recognizes the vanadium redox battery (VRB) as the leading viable solution to efficient large-scale energy storage.  As more companies look to develop and produce vanadium-based battery chemistries, the Report anticipates the potential for rapidly increasing demand of V₂O₅ , which would exhaust current supply levels.

Vanadium Redox Batteries Now Moving into the Mainstream Green Power Market

a+f GmbH, the renewable energy subsidiary of German-based conglomerate Gildemeister, recently  acquired a majority stake in vanadium redox battery manufacturer Cellstrom GmbH.

(News release can be read here at www.af.net)

This pairing is expected to accelerate the sales and interest of Cellstrom’s VRB technology and signifies the establishment of the VRB as a leading battery technology in the burgeoning energy storage market.

Cellstrom’s VRB, named the CellCube, is designed as a stand-alone storage solution for unstable power grids, capable of storing energy produced by solar panels and wind turbines for power delivery around the clock.  To read more on the CellCube, visit www.gildemeister.com/ino/invite_intersolar_10/en/solutions.htm

The amount of V₂O₅ that will be needed for the production of these vanadium redox batteries cannot be met by the current supply of V₂O₅ . 100,000 units of a “CellCube 200” would require approximately 200,000 tonnes of V₂O₅ , which is approximately double the current annual world-wide supply of V₂O₅ .  New vanadium projects, such as the Green Giant project, will need to come online in order to meet this new demand.

The Gildemeister/a+f acquistion of Cellstrom may be the tipping point for vanadium battery technology, as it will move vanadium-based batteries into the mainstream market of Green Power.

Energizer’s Green Giant project is positioned to meet this increase in potential demand and will provide the needed sureness of price and supply that companies such as Gildemeister, a+f and Cellstrom require in order to mass produce vanadium-based battery products.
