African Mining Brief is informed that production at Lerala Diamond Mine in Botswana has resumed, after a nine month hiatus, when the mine was undergoing an upgrade and recommissioning project.
According to Kimberley Diamonds (KDL), the mine owner, during this phase, the plant process is being balanced to optimise recovery efficiency and plant throughput. Personnel, recruited and trained over the past few months, has been working alongside Consulmet’s specialists to commission the plant and to progress to 24/7 continuous operations in the next week.
In August 2015, Kimberley Diamonds (KDL) entered into a lump-sum turnkey contract with engineering firm, Consulmet, to modify the mine’s plant, so that it could treat and recover diamonds at a nominal rate of 200 tonnes per hour.
Following an independent valuation on the mine by Venmyn Deloitte, the planned life of mine (LOM) has been extended from seven to nine years. The firm’s findings showed that the diamond resources and ore reserves were reasonable, based on the information available and assumptions used, and provide a suitable basis for a mineral asset valuation. The project’s contractor was Basil Read Mining Botswana.
