The ore body was discovered in 2016, and feasibility work was done in 2018–2020 with a firm investment decision made in September 2021. Commercial production began in February 2023 with an 8-year lifespan.[2]
Geological setup
The mine comprises 500 km2 (190 sq mi) of leases, covering the Bynoe pegmatite field (BPF) and several pegmatites near Darwin.[2] Specifically, it encompasses the five ore deposits "Grants, Carlton, Sandras, Hang Gong SW, and BP33."[2] The:[3]
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.[3]

Perspective
Core Lithium is developing the mine,[4] 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.[2] The Australian JORC 2012 compliance process estimated 3.45 million tonnes (Mt) of mineral resource at 1.4 percent lithium oxide.[4] Major Project Status (MPS) was granted by the Australian government in March 2021, recognizing the strategic significance of the project.[5]
Battery-grade lithium hydroxide was produced as part of the test works on spodumene mineral concentrate sample from the mine in April 2021.[2] Construction began in 2021 and full operational mining commenced in October 2022,[6] with the first shipment of spodumene concentrate being exported from Port Darwin in May 2023.[2]
Development of the mine is an $89 million project. Over the 12-year lifespan of the project 16 million tonnes (35 billion pounds) of ore are expected to be mined. Most lithium concentrate is expected to be exported overseas.[6]
Production and sales
In 2022, Tesla contracted for 110 thousand tonnes (240 million pounds) of spodumene concentrate over four years from the Core Lithium and its Finniss lithium mine.[7][6]
