en.Wedoany.com Reported - Australian-listed exploration company Perpetual Resources Limited has made significant progress at the Igrejinha Lithium and Caesium Project in Minas Gerais, Brazil, in June 2026, confirming a new pegmatite exploration target through trenching operations. The trenching program encountered pegmatite material in all four trenches, with widths ranging from 2 meters to 11 meters.

Perpetual Resources is an Australian listed company focused on the exploration of critical minerals. The Igrejinha project is located in the state of Minas Gerais, Brazil, a globally renowned pegmatite-type lithium metallogenic province rich in rare metal resources such as lithium, caesium, and tantalum. The trenching program implemented by the company was designed to verify pegmatite outcrops identified during surface geological surveys, providing target basis for further drilling operations.

According to Perpetual Resources, the trenching program was carried out at the target area named "Maurício," with a total of four trenches excavated: Trench TR01 revealed a pegmatite width of approximately 10 meters, TR02 at 3.6 meters, TR03 reaching 11 meters, and TR04 at 2 meters. This result confirms the presence of pegmatite mineralization of considerable scale in the area. The company stated that it will continue to expand exploration efforts to determine the true extent and grade of the pegmatite body, laying the foundation for subsequent drilling plans.

Lithium and caesium are key raw materials for the new energy industry and strategic emerging industries. Lithium is widely used in power batteries, energy storage batteries, and consumer electronics batteries; caesium is increasingly important in high-tech applications, particularly in aerospace, defense, and electronics industries, where it holds an irreplaceable position. The discovery of a new pegmatite target by Perpetual Resources in Minas Gerais, Brazil, is of positive significance for expanding the global supply sources of lithium and caesium resources. As exploration progresses, the resource potential of the Igrejinha project will become clearer.
