Core Lithium Kicks Off Open-Pit Mining at Grants Deposit

Why It Matters

The commencement accelerates Core Lithium’s path to cash flow and restores supply to the tight global spodumene market, while demonstrating disciplined execution that can attract investors seeking near‑term returns in the lithium boom.

Key Takeaways

• Core Lithium begins open-pit mining at Grants, part of Finniss operation
• Grants pit holds ~784,000 tonnes ore, targeting 134,000 tonnes SC5 product
• First ore processing slated for September quarter, first shipment December 2026
• Underground BP33 development proceeds with Develop Global as contractor
• Project aims to generate cash flow and re-enter spodumene market in Q4 2026

Pulse Analysis

The global lithium market is tightening as electric‑vehicle sales accelerate, and producers are racing to secure low‑cost, high‑grade ore. Australia, already the world’s largest lithium exporter, continues to attract capital with projects that promise rapid ramp‑up. Core Lithium’s Finniss operation in the Northern Territory is positioned to tap the country’s abundant spodumene resources, leveraging a fully owned deposit and a clear staged‑production plan. By moving from feasibility to active mining within three months, the company signals strong project discipline and aligns with investors’ appetite for near‑term cash generation.

The Grants open‑pit, approved in April, provides access to roughly 784,000 tonnes of ore and is engineered to deliver about 134,000 tonnes of SC5 spodumene concentrate. Core secured the surface‑mining contract with NRW Pty Ltd and appointed Develop Global for underground work at the BP33 deposit, creating a diversified supply chain that reduces operational risk. Blasting and excavation have already begun, with ore feed expected to enter the processing plant in the September quarter. A first concentrate shipment is targeted for the December quarter, positioning Finniss to re‑enter the market before the end of 2026.

From a financial perspective, the near‑term ore source at Grants lowers capital exposure while delivering cash flow as early as Q4 2026. This de‑risking strategy is likely to attract equity partners seeking exposure to the lithium boom without long‑lead‑time projects. Moreover, the simultaneous development of the deeper BP33 underground resource provides a longer‑term production runway, supporting Core’s ambition to become a reliable supplier for battery manufacturers. The timely execution could also bolster Australia’s export capacity ahead of anticipated supply shortages.
