Baixa Grande Project, Salinas Group of Properties

The Baixa Grande target, located within the Salinas group of properties acquired in March 2023, is one of the most promising projects in the Company’s portfolio tested to date. These Salinas properties are located approximately 100 kilometres north of the Company’s Bandeira development project, within the northern section of Brazil’s Eastern Pegmatite Province, a region that is highly prospective for spodumene-bearing pegmatites. The Baixa Grande mineral resource is an important addition to the Company’s total resources, which further solidifies its position as a leading lithium company in the region.

In August 2024, Pilbara Minerals announced the acquisition of Latin Resources and their Colina deposit for AU$559.9 million (US$369.4 million), located directly west of the Baixa Grande deposit. This acquisition marked Pilbara’s first diversification into the Americas, underscoring the quality, quantity and global competitiveness of Brazil’s lithium deposits in this region.

The Baixa Grande MRE is located on a 662-hectare property, a small portion of Lithium Ionic’s large 17,000-hectare land package.
