About Frontier Lithium

Frontier Lithium is a preproduction business with an objective to become a strategic domestic supplier of spodumene concentrates for industrial users as well as battery-grade lithium hydroxide and other chemicals to the growing electric vehicle and energy storage markets in North America. The Company maintains the largest land position and resource in a premium lithium mineral district located in Ontario's Great Lakes region.

About the PAK Lithium Project

The PAK lithium project contains North America's highest-grade lithium resource and is the second largest in North America by size. The project encompasses close to 27,000 hectares and remains largely unexplored; however, since 2013, the company has delineated two premium spodumene-bearing lithium deposits (PAK and Spark), located 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 (25 kilometres northwest of PAK deposit within the project claims). A 2023 Pre-Feasbility Study "National Instrument 43-101 Technical Report Pre-Feasibility Study PAK Lithium Project" by BBA E&C Inc., delivered post-tax NPV(8) of US$1.74 billion and IRR of 24.1% as per the press release disseminated on with an effective date of May 31, 2023, and was filed on Sedar.com.
