Global Geoscience Limited: Exceptionally Wide Zone of Lithium-Boron Mineralisation

Sydney - Global Geoscience Ltd. (ASX:GSC) is pleased to announce the recently obtained results of five diamond drill holes from the South Basin of the Rhyolite Ridge Lithium-Boron Project in Nevada. The holes were drilled by a previous exploration company in 2011, however, the results were not disclosed at the time. They form part of the comprehensive exploration database recently obtained by the Company. Further drill results will be provided over the next one to two weeks as data becomes available.


Highlights

- Exceptional width of lithium-boron-strontium-potassium mineralisation uncovered in diamond drill holes at South Basin, part of the Rhyolite Ridge Project

- Review of five previously undisclosed diamond drill holes delivered results including:

-- 163m of mineralisation in hole SBHC-1

--- 41m at 1892ppm Li (1.01% LCE), 1.22% B, 0.70% Sr and 0.91% K from 89m; and

--- 122m at 1325ppm Li (0.71% LCE), 0.20% B, 0.43% Sr and 0.82% K from 172m

-- 102m of mineralisation in hole SBHC-2

--- 38m at 1920ppm Li (1.02% LCE), 0.95% B, 0.76% Sr and 0.91% K from 72m; and

--- 64m at 1335ppm Li (0.71% LCE), 0.17% B, 0.45% Sr and 0.78% K from 168m

-- 111m intersection of mineralisation in hole SBHC-5

--- 55m at 1793ppm Li (0.95% LCE), 0.57% B , 0.79% Sr and 0.58% K from 23m; and

--- 56m at 1847ppm Li (0.98% LCE), 0.05% B , 1.30% Sr and 1.05% K from 127m

- Mineralisation intersected in these holes outcrops 100m to 300m to the west of the drill holes

- Maiden JORC-compliant Resource estimate at South Basin expected within the next two months

Global's Managing Director, Bernard Rowe commented: "We are extremely pleased to announce these drill results as we compile and assess the recently obtained exploration database. This is clearly a very large mineralised system and whilst our focus is lithium, it is very encouraging to see very significant amounts of boron, strontium and potassium mineralisation in these intersections."

Future Work

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

The Company's current work program includes:

- Compilation and interpretation of exploration data (1-2 weeks);

- Updated Exploration Target at South Basin (1-2 weeks);

- Maiden JORC-compliant Resource estimate at South Basin (2 months); and

- Preliminary metallurgical test work (3 months).


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.
