Lucara Diamond (TSX:LUC) issued a press release today stating that it is on track with the works towards a feasibility study for a potential underground operation at its 100%-owned and operated Karowe diamond mine.

The Karowe mine is located in northern Botswana and hosted the world’s second-largest diamond, which Lucara unearthed in 2016.

According to Lucara, the $14.8-million feasibility study that would allow them to expand operations is on track to be released in H2-2019 and will be carried out by JDS Energy and Mining Incorporated.

The program included a mineral resource update, geotechnical drilling of the country rock and AK06 kimberlite, hydrogeological drilling and modelling, and mining trade-off studies to address risks and issues identified during the PEA.
