About PAK Lithium Project

The PAK Lithium Project encompasses 26,774 hectares at the south end of Ontario's Electric Avenue, the largest land package hosting premium lithium bearing pegmatites in Ontario. The Project covers 65 km of the Avenue length and remains largely unexplored; however, since 2013 the company has delineated two premium spodumene bearing lithium deposits (Pak and Spark) located 2.3 km from each other. A 2021 Preliminary Economic Assessment of a fully-integrated lithium operation utilizing spodumene concentrate generated from the PAK Lithium Project resource to achieve downstream conversion for production of battery-quality lithium chemicals (NI 43-101 Technical report titled "PAK Property" by BBA Engineering Ltd. report issued on April 5, 2021) resulted in a post-tax NPV8% of USD $974M with a 21% IRR. Considerable exploration upside is supported on the PAK Lithium Project through two other spodumene bearing discoveries; Bolt pegmatite located between PAK and Spark deposits, as well as Pennock pegmatite, a further 30 km northwest of PAK within the Project claims.
