Core Lithium has started early works on its BP33 lithium project in the Northern Territory.
BP33 is the second proposed mine at the Finniss lithium operation.
Early works for the project include covered box cut excavation and construction and surface works such as water management and associated infrastructure.
Northern Australia Civil (NAC) was awarded the early works contract.
“The Grants mine has seen us get into production as a lithium miner,” Core Lithium chief executive Gareth Manderson said. “The larger BP33 deposit now has the potential to be the cornerstone asset for Core Lithium.
“Commencing these $45–50 million of early site works to establish the box cut allows the company to work at pace and stay on the critical path for developing the BP33 underground mine while updating the feasibility study in parallel.
“This approach will allow the company to be in the best position to move forward quickly should a final positive investment decision be received.”
Core has commenced its updated feasibility study, which will incorporate the larger BP33 mineral resource. It will also include operating experience and learnings from the pit to plant, along with mining, metallurgical and geotechnical studies.
The final investment decision for BP33 is due to be made in the first quarter of 2024.
