Lucara Announces Completion of its Diamond Recovery Capital Projects

| Sep 12, 2017 | Marketwired

VANCOUVER, BRITISH COLUMBIA--(Marketwired - Sept. 11, 2017) - Lucara Diamond Corp. (TSX:LUC)(BOTSWANA:LUC)(NASDAQ OMX Stockholm:LUC)("Lucara" or the "Company") is pleased to announce the completion of the Mega Diamond Recovery ("MDR") and the Sub-middles XRT capital projects within budget and ahead of schedule.

The Company's MDR circuit treats material in the size range between 50mm and 120mm and is located directly post the primary crusher and ahead of the process plant. This design maximizes the upfront recovery of exceptional diamonds prior to the comminution processes where diamond damage may occur and revenue lost. Commissioning of the circuit has been completed and the system has been integrated into the existing process stream.

The sub-middles XRT circuit processes material in the size range between 4mm and 8mm. The sub-middles circuit has replaced the need for a dense medium circuit and five diamond recovery unit processes for treating diamonds within this size fraction. The commissioning of the circuit has been completed and verification of the diamonds recovered within this size frequency distribution is being confirmed against historical recoveries.

William Lamb, President and CEO, commented"The commissioning of the MDR and Sub-middles XRT circuits advances the Company's ability to efficiently recover its diamonds and maximize value for its exceptional diamonds. The Sub-middles XRT circuit cost effectively processes the variable yield material from the south lobe through the utilization of a single unit process which reduces feed to the more costly concentration and recovery processing units. The completion of these two capital projects concludes our major capital expenditures for upgrading the process facilities, all of which have been funded from internal cashflows."

Lucara further announces the launch of its virtual reality website. A site tour can be facilitated through the web portal: http://www.lucara360.com/tour/

On behalf of the Board,

William Lamb, President and CEO
