Perpetual Resources (ASX:PEC) has identified a high-grade lithium soil anomaly at its Igrejinha project in Brazil, with soil sampling work revealing an extended trend of LCT (lithium, cesium and tantalum) pegmatite.

The anomaly, which comes before maiden drilling next month, was picked up following Perpetual’s 220-sample soil and auger geochemical program and indicated that the strike length of the outcropping high-grade lithium-bearing pegmatite could expand to more than 1.4 kilometres.

This should open the door for further mineralisation to be found along strike, and builds on previously reported rock chip samples, which revealed more than 7% Li₂O (lithium oxide) and 5.3% Cs₂O (cesium monoxide) at the project.

Adding to this, a significant new lithium target has also been picked up through first-pass soil sampling done 2.3 kilometres southeast of the main pegmatite prospect, with results going beyond 400 ppm Li₂O.

Perpetual’s exploration manager, Allan Stephens, said this sampling work has underscored the value of Perpetual’s assets. “These latest results reinforce the scale and potential of the Igrejinha Project, with the LCT corridor now stretching over 1.4 km and remaining open along strike,” he said.
