About Frontier Lithium Inc.
Frontier Lithium is a Sudbury based, publicly listed, junior mining company with the largest land position in an emerging premium lithium mineral district located in the Great Lakes region of northern Ontario. 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 has recently commenced a Preliminary Economic Assessment study 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 the PAK Lithium Project
The PAK Lithium Project encompasses 26,774 hectares at the south end of Ontario's Electric Avenue, which is the largest land package hosting lithium bearing pegmatites in Ontario. The Project covers 65km 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. Recently, Frontier confirmed the presence of spodumene with the Pennock Lake pegmatite occurrence a further 30km along Frontier's PAK Lithium Project. Frontier's premier Great Lakes location is advantaged by favorable geology, proven metallurgy with access to intermodal hubs, infrastructure, power, and mining and downstream lithium processing expertise.

The PAK deposit has a mineral reserve in the proven and probable categories of 5.77 MT averaging 2.06% Li₂O. The deposit hosts a rare technical/ceramic grade spodumene with low inherent iron (below 0.1% Fe₂O₃). The Spark Deposit, winner of the "2019 Discovery of the year award" has a mineral resource estimate of 3.2 MT averaging 1.59% Li₂O (indicated) and 12.2 MT averaging 1.36% Li₂O (inferred), as per the NI 43-101 Technical Report, "PAK prefeasibility study, Spark resource estimation" by WSP Canada Inc. and Nordmin Engineering Ltd., updated on March 23, 2020. The Company recently initiated a Preliminary Economic Assessment study for a fully integrated project producing lithium hydroxide from the PAK Lithium Project.
