Lucara Diamond Corp continues to make progress with the feasibility study for a potential underground operation at its 100%-owned and operated Karowe diamond mine, in Botswana. Following the release of a positive preliminary economic assessment (PEA), the company last year embarked on a technical programme to support a feasibility study for a potential underground operation at Karowe, with the aim of extending the mine life from 2026 to at least 2036.
