About Frontier Lithium

Frontier Lithium Inc. (TSX-V: FL) is an exploration and development mining company with

headquarters and assets in

Northern Ontario

, a Tier1 mining jurisdiction. The Company's PAK

Lithium Project represents a high-grade, large tonnage, pure lithium resource in a new, premium

lithium mineral district in northwestern

Ontario

. Strategically located in the Great Lakes region near

the United States

border, Frontier is developing the first fully integrated lithium mining and processing

operation in

Ontario

with an aim to become

Canada's

lithium champion and a significant supplier of

spodumene concentrates and battery-grade lithium chemicals to the growing electric vehicle and

About the PAK Lithium Project

The PAK Lithium Project contains

North America's

highest-grade lithium resource and is the largest

in

Ontario

by size. The claims encompass more than 26,000 hectares and remains largely

unexplored; however, since 2013, the Company has delineated two premium spodumene-bearing

lithium deposits (PAK and Spark), located only 2.3 kilometres apart. Exploration is continuing on the

project through two other spodumene bearing discoveries: the Bolt pegmatite (located between the

PAK and Spark deposits), as well as the Pennock pegmatite located 25 kilometres northwest of

PAK deposit within the project claims. A 2023 Pre-Feasibility Study titled ""National Instrument 43-

101 Technical Report PFS PAK Lithium Project"" authored by BBA E&C Inc., delivered a 24- year

project life, at a post-tax NPV(8%) of

US$1.74 billion
