Stimson

Geology Overview

The Stimpson project is strategically located along strike of Power Metals’ Case Lake Li-Cs-Ta (LCT) deposit, straddling the same boundary between the Quetico and Abitibi subprovinces. Importantly, a historical drill log at Stimpson noted three intervals, the largest being 39.8m (60.0 – 99.8m) logged as a ‘granitic complex’, an unknown portion of which was pegmatite containing possible spodumene in DDH PT94-11 (OGS Assessment Record 42H02SE0010).

This historical result provides evidence of a potential Li-bearing pegmatite system on the Stimpson project that Libra plans to test through future drilling. Although Libra is primarily targeting spodumene, the key lithium-bearing mineral found in LCT pegmatites, the Company will also evaluate the potential for pollucite, which is the main cesium-bearing mineral in LCT pegmatites.

The Company notes that while mineralization on nearby or adjacent projects is not necessarily indicative of mineralization at Stimson, the Quetico-Abitibi subprovince boundary is proven to be fertile for hosting both pollucite and spodumene.
