About Rhyolite Ridge Lithium-Boron Project

Rhyolite Ridge is a sedimentary-type lithium-boron deposit located in southern Nevada and is 100% owned by Global Geoscience. The project has the potential to become a significant, near-term producer of lithium carbonate and boric acid in America.

Rhyolite Ridge consists of two sedimentary basins located four kilometres apart: South Basin (9 km2) and North Basin (20 km2). South Basin includes an Indicated and Inferred Resource of 3.4 million tonnes of lithium carbonate and 11.3 million tonnes of boric acid, making it one of the largest lithium and boron deposits in North America. The Resource is open in most directions and is likely to increase in size with additional drilling. North Basin hosts thick, shallow lithium-boron mineralisation drilled by wide-spaced holes that are not yet sufficient to estimate a resource. The South Basin Indicated and Inferred Resource contains a high-grade Li-B zone comprising 65Mt at 1.0% Li2CO3 and 9.1% H3BO3 for a total of 650,000 tonnes of lithium carbonate and 5.9 million tonnes of boric acid.

The mineralisation is hosted within thick, shallow, flat-lying sedimentary rocks, representing a potential third source of lithium. Lithium and boron occur within acidsoluble minerals including searlesite and sepiolite, making the deposit amenable to acid-leaching without roasting.

Rhyolite Ridge is located close to existing infrastructure and is 25km west of Albermarle's Silver Peak lithium mine and 340km by paved road from the Tesla Gigafactory. It has the potential to be a strategic, long-life, low-cost and reliable source of lithium and boron.
