Core Lithium’s BP33 underground contract: design and operations lens for engineers
Reviewed by Joe Ashwell
First reported on International Mining – News
30 Second Briefing
Core Lithium has awarded a three-year underground mining contract, with a two-year extension option, to Dev Mining Services (a Develop Global subsidiary) for the BP33 deposit that underpins the Finniss lithium operation in Australia’s Northern Territory. The scope covers all underground production activities at BP33, shifting Finniss from open-pit to a combined open-pit/underground operation and locking in a medium-term mining services provider. For engineers and contractors, the deal signals forward work on underground development, ground support and lithium ore handling in a relatively young NT hard-rock lithium district.
Technical Brief
- Contract term is three years with a further two-year extension available by mutual agreement.
- Dev Mining Services Pty Ltd is the appointed underground mining contractor, owned by Develop Global Limited.
- Scope is explicitly limited to underground mining services at the BP33 lithium deposit.
- BP33 is located in Australia’s Northern Territory, forming part of the Finniss lithium operation.
Our Take
Within our mining project coverage, lithium pieces like this one around Core Lithium’s Finniss operation are a small subset compared with iron ore and gold, signalling that Northern Territory hard‑rock lithium developments are still relatively early-stage in our database.
Because this sits in the Projects/Contract Award segment of our coverage rather than M&A or financing, it points to Core Lithium prioritising near-term execution at Finniss over corporate transactions, which typically dominate lithium headlines when prices are volatile.
