Frontier Lithium Achieves Milestone with Production of Battery Quality Lithium Hydroxide with Mini-pilot Plant

by ahnationtalk on October 20, 202157 Views


  • Frontier Lithium has successfully produced battery grade lithium chemicals from its own high-quality spodumene resource from the PAK deposit, part of the PAK Lithium Project in Ontario.
  • Frontier is currently conducting additional bench-scale testing of a third-party’s patented alkaline process route to produce lithium hydroxide from the company’s second Spark ‘open pitable’ resource.
  • This work builds on Frontier Lithium’s plan to build a fully-integrated lithium chemicals company. Data generated is contributing to the on-going internal scoping/trade-off study assessing various process options to be utilized for piloting to support Pre-Feasibility Study (PFS).

Frontier Lithium Inc. (“Frontier” or “the Company”) has successfully produced battery-quality lithium hydroxide monohydrate (LiOH-H2O) through a reputable third-party firm using its crystallization process technology from a purified lithium hydroxide (LiOH) solution produced by Frontier Lithium. The lithium salts were produced from ‘ore-to-hydroxide’ sulphate conversion route by a mini-pilot plant using core samples taken from the PAK Lithium Project’s(1) PAK deposit. Test work results are shown in Table 1.

Trevor Walker, President and CEO of Frontier Lithium stated, “We continue to progress, de-risk and execute on our plan to build a fully-integrated lithium chemicals company to service the global battery and electric vehicle industry.” He also added “We are looking to complete lithium chemicals process selection by year-end and will then commence subsequent piloting and demonstration programs necessary to deliver the feasibility of an optimized process with innovative technology necessary for building a commercial lithium chemical processing plant in North America.”

The program results reflect Frontier’s ability to produce concentrate and lithium hydroxide from the PAK Lithium Project. The Government of Ontario is financially supporting the program of conventional direct conversion sulphate and novel sulfate-free processing of spodumene concentrates. The test work will support the PFS study currently being conducted to assess the viability of a vertically integrated chemical company through operation of a spodumene mine and concentrator at the PAK Lithium Project to feed lithium chemicals plant operation in the Great Lakes region of North America.

About Frontier Lithium

Frontier Lithium is a pre-production business that is targeting to become a manufacturer of battery-quality lithium hydroxide to support electric vehicle and battery supply chains in North America. Frontier owns 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 continues to have significant exploration upside with potential to increase the lithium resource. It is a pure play lithium company with the largest land position in the Electric Avenue, a premium lithium mineral district located in Northern Ontario.

About the 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 kilometres of the Electric Avenue’s length and remains largely unexplored; however, since 2013, the company has delineated two premium spodumene-bearing lithium deposits (Pak and Spark) located 2.3 kilometres 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 (National Instrument 43-101 technical report titled “Pak Property” by BBA Engineering Ltd., issued on April 5, 2021) resulted in an after-tax net present value (discounted at 8 per cent) of $974-million (U.S.) with a 21-per-cent internal rate of return. Considerable exploration upside is supported on the Pak lithium project through two other spodumene-bearing discoveries: the Bolt pegmatite (located between the Pak and Spark deposits) as well as the Pennock pegmatite (a further 30 kilometres northwest of Pak within the project claims).
