Exploration database to fast-track maiden JORC Resource at South Basin

Highlights

• Comprehensive database of historic exploration results obtained for the Rhyolite Ridge Lithium-Boron Project in Nevada

• Data to be used to fast track a maiden JORC-compliant Resource estimate

• 8800m of RC and Diamond drilling undertaken at South Basin in 2010-2011

• Drill core from 21 Diamond drill holes to be used for metallurgical test work

• The Company estimates that it would cost over A$3M to replicate all of the historic work that has been undertaken at South Basin

• Substantial time and cost saving allowing the rapid progression toward a decision to commence a pre-feasibility study

• Further technical information will follow in the near future as data is compiled and interpreted

  Summary

  Global Geoscience Limited ("Global" or the "Company") is pleased to announce that it has obtained access to a substantial exploration database relating to historic exploration completed at the South Basin area of the Rhyolite Ridge Lithium-Boron Project in Nevada. The exploration work was completed from 2010-2011 by American Lithium Minerals Inc, in conjunction with Japan Oil, Gas and Metals National Corporation (JOGMEC).

  The database includes:

• 5135m of Diamond drilling (21 holes), including assays, logs, core, coarse rejects and pulps

• 3665m of RC drilling (15 holes), including assays, logs, chip trays, sample splits and pulps

• 465 surface and trench rock chip samples with multi-element analysis including pulps

• Geological maps, cross-sections and various reports

  The Company estimates that the cost to replicate this work would be in the order of A$3M. Most of the data is unpublished information and will be compiled, verified and interpreted prior to release of further technical information.

  The Company is also in the process of collating data about the North Basin where US Borax drilled 57 percussion holes (15,000m) in the 1980's and discovered a large boron deposit. US Borax stated that their drilling defined the second largest deposit of boron in the United States and that the deposit contains elevated levels of lithium and strontium (Esmeralda Energy Company, 2008).

  Future Work

  The exploration database will expedite the calculation of a maiden JORC-compliant Mineral Resource estimation and provide valuable sample material for metallurgical and other test work.

  The Company's current work program includes:

• Compilation and interpretation of exploration data

• Delineation of zones of shallow, high-grade mineralisation at the North and South Basin

• Recalculation of the Exploration Target at South Basin

• Preliminary metallurgical test work

• Maiden JORC-compliant Resource estimate at South Basin

• Decision to commence pre-feasibility

About Rhyolite Ridge Lithium-Boron Project

The Rhyolite Ridge lithium-boron project (22km2) is located close to existing infrastructure in southern Nevada. The project has potential as a long life, low cost source of lithium, boron and strontium. Two sedimentary basins (North and South) contain thick, shallow and flat-lying zones of mineralisation. The mineralisation is hosted by carbonate-rich, fine-grained sediments (marl) that were deposited in a shallow lake environment. The two basins have a combined surface area of approximately 17 sq km. Previous exploration includes over 100 drill holes. Similar "clay-type" lithium deposits include Sonora Lithium-Potassium (Bacanora Minerals, Mexico) and Jadar Lithium-Boron (Rio Tinto, Serbia)

Global Geoscience has the exclusive right to purchase 100% interest in the project from the owner, a private Nevada company.

Lithium content expressed in ppm is converted into Lithium Carbonate Equivalent (LCE) by multiplying by 5.32. LCE does not include boron and strontium content.
