Canadian authorities to support Frontier Lithium’s project in Ontario

08 october 2024

The government of Canada has approved a funding of up to C$6.1 million from the Critical Minerals Infrastructure Fund (CMIF) to Frontier Lithium’s PAK project in Ontario.

The infrastructure funding includes environmental studies for a 56-km road towards the lithium mine; and engineering, design and permitting studies for a substation and electricity transmission line.

“As we move forward on our path to building the first fully integrated lithium mining-and-processing operation in Ontario, we know our objectives align nicely with that of the CMIF – to address infrastructure gaps, reduce emissions, and advance reconciliation with Indigenous peoples,” said Frontier’s president and CEO Trevor Walker.

The company is conducting exploration at PAK project which consists of several spodumene-bearing lithium deposits. The prefeasibility study showed that the project would have a mine life of 24 years with an internal rate of return of 24.1%.
