HIGHLIGHTS

Safety: Karowe had one lost time injury during the quarter, resulting in a Lost Time Injury Frequency Rate ("LTIFR") of 0.15 for the 12 months to June 30.

Cash flows and operating margins: The Company achieved second quarter tender proceeds of $95.0 million ($849 per carat) from sales of 111,902 carats of diamond. This includes proceeds of $24.7 million, which were received after the quarter. Total proceeds for the first half of the year were $128.6 million ($586 per carat) from the sale of 219,370 carats of diamond. Total Company proceeds for the half year of $586 per carat at an operating cost of $124 per carat resulted in a 79% operating margin of $462 per carat.

Following the second quarter the Company concluded its second exceptional stone tender in July for proceeds of $40.1 million, which results in full year to date proceeds of $168.6 million at a sales price of $764 per carat.

Net cash position: The Company's quarter-end cash balance was $82.1 million compared to a net debt position of $29.6 million in the previous year and $49.4 million of cash at the end of 2013. The June cash balance of $82.1 million excludes $24.8 million of cash received after the quarter end.

Karowe operating performance: Karowe's operating performance exceeded plan during the period in terms of ore and waste mined and carats recovered. The Company recovered a record number of 252 special stones (+10.8 carats) during the period with an average size of 27.84 carats.

Adjusted Earnings per share: Adjusted earnings per share is $0.10 per share for the three month period ended June 30, 2014 and $0.13 per share for year to date.

Dividends paid: The Company paid its inaugural semi-annual dividend of 2 cents per share on June 19. The Company is forecast to pay its year-end and special dividend in December. The special dividend will be determined based on revenues generated from the exceptional stone tenders during the year, the Company's financial position and its expected cash requirements in future periods.

Outlook: The Company has increased its revenue forecast by approximately 60% for the year to between $240-$250 million based on year to date sales, current diamond inventory and its forecast production. The Company has maintained its overall cost outlook for the mine of between $31-$33 per tonne ore processed.

William Lamb, President and Chief Executive Officer commented "Lucara had a strong first half of the year and this has continued into the third quarter with our second exceptional stone tender in July, resulting in total year to date proceeds of $169 million, achieving $764 per carat. Following these results and our current diamond inventory we have increased our full year revenue guidance to $240-$250 million while maintaining our original carat production and operating cost guidance due to strong operational delivery at Karowe. To the end of June, the mine sold 54 diamonds larger than 50 carats, including 11 diamonds larger than 100 carats and 30 diamonds selling for more than $1 million. The sustainable recovery of special diamonds has enabled the addition of the third exceptional stones tender which will be held in the fourth quarter."

FINANCIAL HIGHLIGHTS

RESULTS OF OPERATIONS

Karowe Mine, Botswana

The Karowe mine performed well during the second quarter of 2014. Tonnes of ore mined exceeded plan during the period. Waste mined for the push back to open up access to the south lobe accelerated during the period, recovering the first quarter deficit and is back on track for the year to date planned volumes.

The process plant performed well during the quarter with mill throughput and carats produced in excess of plan. Carats produced were lower than the prior period due to mining a lower grade area in accordance with the mine plan. A total of 252 special stones (+10.8 carats) were recovered during the quarter at an average size of 27.84 carats. This represents a record quarter both in frequency and average size of specials recovered.

REVIEW OF PROJECTS

Mothae Diamond Project, Lesotho

The Mothae project is located in northeast Lesotho and is a large low grade kimberlite containing a population of large, high value Type IIa diamonds.

The Company is currently reviewing a number of development options for Mothae.

Karowe, Plant Optimization Project

The Plant Optimization progressed well during the period. The Company has spent approximately $8 million and committed a further $27 million of expenditure to date. At the end of the second quarter, project progress was on schedule and within plan. The impact of industrial action within the steel industry in South Africa, who was on strike between July 1 and July 28, is still being assessed. The project is now forecast to be complete during Q2 2015 and is not expected to impact on 2015 production.

Karowe Mine, Botswana

Revenue is forecast between $240-$250 million based on the sale of between 400,000 to 420,000 carats.

Karowe is still forecast to process between 2.2 - 2.4 million tonnes.

Forecast for ore mined remains at between 3.0 - 3.5 million tonnes and waste mined between 10.0 -11.0 million tonnes.

Karowe's operating cash costs (Non-IRFS measures) are expected to remain between $31 - $33 per tonne ore treated.

The Company is forecasting that the plant optimization project will cost up to $55 million, an increase from the $45-$50 million in previous guidance. The additional cost includes the purchase of an additional XRT diamond sorting machine which will be installed early, in the capacity of a large diamond recovery unit. Once the optimization project has been completed, this unit will be used as an audit machine as well as for future development work. The XRT machine may also be used for future new development work. The Company has also included costs to mitigate the impact of industrial action in the steel industry in South Africa, which commenced on July 1 and ended July 28. The Company is forecasting a Q2 2015 completion date for the plant optimization project and this timeline is not expected to affect 2015 production. Sustaining capital expenditures remains at $3.5 million.
