Global Geoscience Limited - Thick Lithium Mineralisation at North Basin

Sydney - Global Geoscience Ltd. (ASX:GSC) ("Global" or the "Company") is pleased to announce drilling results from historic exploration completed at North Basin, part of the Company's Rhyolite Ridge Lithium-Boron Project in Nevada. The drill results show that North Basin hosts thick, shallow zones of lithium-boron mineralisation over an area of at least five square kilometres (sq km).

Highlights

- Thick, shallow intersections of lithium-boron mineralisation in wide-spaced drilling (historic) at North Basin

- Shallow, 100m to 260m thick intersections in 9 holes drilled over an area of 5 sq km

- Individual 3m intervals up to 3890ppm Li (2.07% LCE) indicate potential for high-grade zones between and adjacent to wide-spaced holes

- Intersections include:

-- 33m at 2290ppm Li (1.22% LCE) and 0.38% B from 15m within a zone of 125m at 1868ppm Li (0.99% LCE) and 0.21% B from 12.2m in drill hole FLH-38

-- 67m at 1645ppm Li (0.88 %LCE) and 0.49% B from 24m within a zone of 259m at 1597ppm Li (0.85% LCE) and 0.16% B from 15.2m in drill hole FLH-37

-- 201m at 1364ppm Li (0.73% LCE) and 0.74% B from 27m in drill hole FLH-19

- Drilling program to test for high-grade zones and obtain metallurgical samples to commence in late October

- Maiden JORC-compliant Resource estimate at South Basin due in early October

Global's Managing Director, Bernard Rowe commented: "The results from wide-spaced drilling at North Basin are highly encouraging, with thick zones of lithium-boron mineralisation starting from only 10m below surface and extending over an area of at least 5 sq km. Our upcoming drill program will target high-grade zones at both North and South Basin."

Drill Results from North Basin

Drilling at North Basin was undertaken by US Borax during the 1980's using a combination of rotary and percussion drilling methods. The results show very thick (100-260m) zones of lithium-boron mineralisation at very shallow depths (<30m) over an area of approximately 5 sq km. Drill holes are spaced at 400 to 900m. Higher-grade mineralisation occurs in the shallowest part of each intersection. Individual 3m intervals up to 3890ppm Li (2.07% LCE) indicate potential for higher-grade zones between and adjacent to the wide-spaced drill holes.

Metallurgical Test Work

The Company has commenced metallurgical test work and economic modeling under the direction of consulting engineers, Mr Silvio Bertolli and Mr Peter Ehren. Mr Bertolli and Mr Ehren are globally recognized experts in the lithium mining industry. Key parts to the initial metallurgical study are:

- Metallurgical mapping of the deposit

- Optimum upgrading conditions for lithium and boron (beneficiation)

- Best leaching conditions aimed at minimizing reagent and energy consumption

- Processing steps required to separate lithium, boron and potassium and achieve commercial products

South Basin Resource Estimation

RungePincockMinarco is undertaking a maiden JORC-compliant Resource estimation at South Basin using the existing database of 21 core and 15 RC holes drilled in 2010-2011. The drill holes provide sufficient information to complete the Resource estimate without the need for additional drilling. The Resource estimate is on schedule for completion in early October 2016.

Work Program In Progress

- Maiden JORC-compliant Resource estimation at South Basin (Oct 2016)

- Drilling of high-grade targets at North and South Basins (Dec Qtr)

- Preliminary process and metallurgical test work and economic modelling (Dec Qtr).

About Rhyolite Ridge Lithium-Boron Project

The Rhyolite Ridge lithium-boron project (22km2) is located close to existing road and power infrastructure in southern Nevada. The project has potential as a strategic, long-life, low-cost source of lithium, boron and potassium. Two sedimentary basins (North and South) contain thick, shallow, flat-lying zones of lithium-boron-potassium mineralisation. The mineralisation is hosted within carbonate-rich, fine-grained sediments (marl) that were deposited in a shallow lake environment. Previous exploration includes over 100 drill holes. Global Geoscience has the exclusive right to purchase 100% interest in the project from the owner, a private Nevada company.
