Finniss Lithium Operations
Owned and operated by Core Lithium, the Finniss Lithium Operation is a hard-rock lithium mine located on the Cox Peninsula in Australia’s Northern Territory. Located 88 km south-west of Darwin, with direct access to Darwin Port, it is the Northern Territory’s first lithium mine.
Commencing production in October 2022, it transitioned to temporary care and maintenance in mid-2024 due to a decrease in current demand for lithium. Mining resumed in May 2026 at the Grants Open Pit and on the BP33 Boxcut.
In 2025, Core Lithium released its restart study for a potential 20-year mine life, initially centred on scalable underground mining at the Grants and BP33 deposits, with plans to progressively develop the broader Finniss resource inventory. Core Lithium entered into a marketing and distribution arrangement with Glencore International AG for the sale of lithium products from the Finniss Operation, with long-term offtake agreements available.
