PERTH (miningweekly.com) – ASX-listed Lake Resources has launched a Definitive Feasibility Study (DFS) for its Kachi lithium brine project in Argentina.
A 2020 Pre-Feasibility Study (PFS) estimated that the project could have an annual production of 25,500 t / y of battery-grade lithium carbonate over a mine life of around 25 years, with the project likely requiring a seed capital investment of $ 544 million. .
The PFS estimated an after-tax net present value of $ 748 million and an internal rate of return of 22%, with annual sales over the life of the project targeted at over $ 7 billion.
“The official launch of DFS is a key step for Lake to bring the Kachi Project into production with sought-after environmental, social and corporate governance credentials as the transition to electric vehicles accelerates,” said Lake Resources. MD Steve promnitz.
“Transition studies are underway from the PFS and now Hatch’s formal engagement has taken place,” he added.
Associated workflows that will run in parallel with the DFS include the Environmental Impact Assessment, continued community engagement, and a demonstration plant that will be commissioned at the site later in 2021.
The DFS is expected to be completed by the first quarter of 2022.
