Lucara starts shaft sinking at Botswana expansion project

Canada-based miner Lucara has started sinking the main shaft at its Karowe diamond mine expansion project, in Botswana, although it says that the transition from pre-sinking has taken longer than planned. The TSX- and LSE-listed miner says that it has identified opportunities to decrease the main sink cycle times, which should limit the impact to the project’s schedule.
