Шаблон:Short description Шаблон:Use dmy dates
The Finnis Lithium Project is a lithium mine situated near Darwin, Northern Territory, Australia. The project is being developed by Core Lithium.
The ore body was discovered in 2016, feasibility work was done 2018–2020 with a firm investment decision made in September 2021. Commercial production began in February 2023 with an 8-year lifespan.[1]
Geological setup
The mine encompasses five ore deposits: specifically "Grants, Carlton, Sandras, Hang Gong SW, and BP33. The project area is made up of Шаблон:Cvt of leases covering the Bynoe pegmatite field (BPF) and comprising several pegmatites near Darwin.[1]
The "ore bodies of the Finniss lithium project are characterised as lithium-cesium-tantalum (LCT) pegmatite deposits that are hosted within the Burrell Creek metasedimentary rock formation. The pegmatites at the deposits comprise lithium-bearing spodumene, quartz, albite, microcline as well as mica" with a consistent lithium content across the ore body.[2]
Description
Core Lithium is developing the project,[3] having completed a pre-feasibility study (PFS) in June 2018 and a definitive feasibility study (DFS) in April 2019. Revisions to the feasibility study were completed in 2020 to incorporate underground mining methods in the mining plan. A revised DFS was completed in July 2021 outlining a project that will occur in multiple stages. The first stage will involve open-pit mining near Grants and Hang Gong, as well as underground mining at the Grants, BP33, and Carlton prospects.[1] The Australian JORC 2012 compliance process estimated 3.45 million tonnes (Mt) of mineral resource at 1.4 percent lithium oxide.[3] Major Project Status (MPS) was granted by the Australian government in March 2021, recognizing the strategic significance of the project.[4]
Battery-grade lithium hydroxide was produced as part of the test works on spodumene mineral concentrate sample from the project in April 2021.[1] Construction began in 2021 and full operational mining commenced in October 2022,[5] with the first shipment of spodumene concentrate being exported from the Port of Darwin in May 2023.[1]
Development of the mine is an $89 million project. 16 million tonnes of ore are expected to be mined over the 12-year lifespan of the project. Most lithium concentrate is expected to be exported overseas.[5]
Production and sales
In 2022, Tesla, Inc. contracted for 110,000 tonnes of spodumene concentrate over four years from the Core Lithium and the Finniss lithium mine.[6][5]
