Frontier Lithium PFS work indicates favourable ground conditions for potential open pit structure at PAK Lithium Project
Sudbury, Ontario, June 22, 2017 – Frontier Lithium Inc. (TSX.V: FL) (the “Company”) is pleased to announce new drilling results for its PAK Lithium Project, in the Red Lake mining district. As part of ongoing Pre-Feasibility Study (PFS) activities, the design brief, conducted by Golder Associates (Sudbury, ON, Canada) and based on the 2017 winter drilling program, outlined slope design recommendations for the Company’s lithium deposit and indicated favourable conditions for an open pit structure.
In March 2017, Frontier successfully completed four (4) geomechanical drill holes with core orientation and packer testing which was followed by laboratory strength testing. For the purpose of Frontier’s pre-feasibility study, results of the program suggest that rock mass failure should not be a concern given the very strong intact rock strength of proposed pit walls for an open pit up to 200m deep. Slope design will be controlled by the stability of individual benches, meaning the quality of blasting and the prevalence of structures that undercut the bench face angle. Should Frontier perform a future Definitive Feasibility Study, it has been recommended that some additional drilling be performed by the Company.
Frontier also successfully conducted twenty-two (22) sampled boreholes for the soils geotechnical data collection program for the PFS design of a Tailings Management Facility (TMF), as well, fifteen (15) monitoring wells were successfully installed for a baseline hydrogeology study being conducted on the Project.
“These studies indicate that the ground conditions and general site topography seem to provide favourable conditions for a low cost mining scenario with potential open pit operations at the PAK Lithium Project,” remarked Trevor Walker, President and CEO of Frontier. In addition, the Company confirms it has successfully converted the mining claim where the Pakeagama Lake Deposit is located into a twenty-one (21) year lease agreement by the Province of Ontario.
