The company maintains 100% interest in the PAK Lithium Project which contains one of North America's highest-grade, large tonnage hard-rock lithium resources in the form of a rare low-iron spodumene. The Project has significant upside exploration potential. Frontier is a pre-production business that is targeting the manufacturing of battery quality lithium hydroxide in the Great Lakes Region to support electric vehicle and battery supply chains in North America. Frontier maintains a tight share structure with management ownership approximately 30% of the Company.

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 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 located 2.3 km from each other at the southwestern end of the project. The recent Preliminary Economic Assessment initial results announced an post-tax NPV(8%) of USD 974M with a 21% IRR.

The PAK deposit hosts a rare "technical grade" spodumene maintaining low inherent iron levels (below 0.1% Fe₂O₃) and contains a pit constrained mineral resource in the measured and indicated categories of 5.4 million tonnes averaging 1.99% Li₂O and a pit constrained inferred mineral resource of 0.60 million tonnes averaging 1.97% Li₂O. The PAK deposit also contains an underground constrained mineral resource in the measured and indicated categories of 1.3 million tonnes averaging 2.15% Li₂O and an underground constrained mineral resource in the inferred category of 2.1 million tonnes averaging 2.38% Li₂O. The Spark deposit is located only 2km northwest of the PAK deposit and contains a pit constrained mineral resource estimate of 3.3 million tonnes averaging 1.59% Li₂O in the indicated category and a pit constrained mineral resource of 15.7 million tonnes averaging 1.31% Li₂O in the inferred category., as per the initial results supporting an upcoming NI 43-101 Technical Report, "2020 Preliminary Economic Assessment, Fully Integrated PAK Lithium Project" by BBA Engineering Ltd.

Frontier has also confirmed the presence of spodumene with the Bolt pegmatite, between PAK and Spark deposits and the Pennock Lake pegmatite occurrence a further 30 km along the Project. Frontier's premier Great Lakes location is advantaged by favorable geology, proven metallurgy with access to intermodal hubs, infrastructure, power, and mining along with downstream lithium processing expertise and auto OEM's.
