Global Geoscience Limited: Rhyolite Ridge - A Unique and Strategic Lithium-Boron Deposit

Sydney - Global Geoscience Ltd. (ASX:GSC) is pleased to provide the Company's latest Presentation at Lithium Supply & Market Conference, Montreal.

Rhyolite Ridge - A Unique and Strategic Lithium-Boron Deposit

Hard-Rock Sedimentary Lithium Deposit

- Large, flat-lying and at surface
- Simple, low-cost mining and milling

Fundamentally Different than Other Known Sedimentary-Type Lithium Deposits

- Boron-rich
- Mineral searlesite (sodium boro-silicate) makes up over 40% of the rock (by weight)
- Low-clay content
- Carbonate minerals are relatively coarse and can be removed via flotation
- Amenable to simple acid leaching with low acid consumption
- Roasting is not required
- New technology is not required

Major Advantages Over Other Lithium Deposits

- Nevada location
- Hard-rock deposit, low-cost mining and milling compared to pegmatite deposits
- Significantly smaller environmental footprint compared to a brine deposit
- Two revenue streams - significant player in both lithium and boron market
- Down-stream value add - lithium carbonate/hydroxide and boric acid produced on site
- Lower Capex than most brines, lower Opex than spodumene/pegmatite based converters

Rhyolite Ridge Project Overview

Large Property, Simple Ownership
- 29km2, 100% ownership interest
- 2 basins located 4km apart

Deposit Type
- Sediment-hosted (stratiform) lithium-boron deposit
- Main ore mineral is searlesite, a sodium boro-silicate mineral

North Basin (20km2)
- Explored for boron in 1980's by US Borax
- 37 rotary/percussion drill holes
- 100-260m thick intersections in 9 holes drilled over an area of 5 km2
- Reportedly 2nd largest boron deposit in USA at the time

South Basin (9km2)
- Explored for lithium in 2010-2011 by JOGMEC
- 15 RC and 21 diamond drill holes
- Maiden Resource Estimate by GSC - Oct 2016

A Unique and Strategic Asset in Nevada

- Hard-rock sedimentary Li-B deposit
- 100% ownership
- Fundamentally different other known sedimentary-type lithium deposits
- Major advantages over other lithium deposits
- Two revenue streams
- Lithium carbonate/hydroxide and boric acid produced onsite
- Significant player in both lithium and boron markets
- Building a strong and experienced team to deliver
- We aim to be a near-term, cost-competitive, major producer of lithium carbonate and boric acid
