VANCOUVER, BRITISH COLUMBIA--(Marketwire - Dec. 12, 2011) - Lucara Diamond Corp. (TSX:LUC)(BOTSWANA:LUC)(NASDAQ OMX First North:LUC) ("Lucara" or the "Company") is very pleased to report outstanding results from its second tender of rough diamonds recovered from the Mothae mine in Lesotho. A total of 7,190 carats in 28 sale lots were offered on tender in Antwerp between December 5 through 9, 2011. All 28 lots received multiple bids and winning offers resulted in an average price of US$893 per carat and gross proceeds of US$6.4 million, an increase from Lucara's first diamond sale earlier in the year.

The three stones with the highest per carat value, all Type IIa, were a 28.89 carat diamond which sold for $1.6 million ($57,113/ct, a record for Mothae), a 56.51 carat diamond which sold for $2.1 million ($37,019/ct), and a 19.20 carat diamond which sold for $490,000 ($25,520/ct). These prices signify the exceptional quality and size of the stones that are regularly recovered from Mothae.

Mr. William Lamb, President and CEO of Lucara Diamond Corp., commented, "The results of this sale re-confirm the presence of a population of large, top quality diamonds within the Mothae kimberlite and demonstrate that these stones can be recovered with a regularity which greatly enhances the economic potential of the project. We are particularly pleased with the enthusiastic market response to Mothae production, suggesting that we can always expect strong demand for our type of diamonds regardless of market conditions."

The tender was held at the offices of Bonus-Couzyn under the supervision of AGM Diamond Expertise (HK) LTD. The diamonds sold were recovered during the ongoing trial mining at Mothae. Sample grades for the material processed to recover the diamonds were as follows:

The trial mining program at Mothae has been going very well and is expected to be completed in the third quarter of 2012. A total of 720,000 tonnes of kimberlte is scheduled to be processed of which 430,000 tonnes has been processed to date.

A Preliminary Economic Assessment study was contracted to ADP in October 2011 and is expected to be finalized in the fourth quarter of 2012. The objective of the study is to gain a further understanding of the economic potential of the Mothae project and to define the capital expenditure and operating costs for mine development to a pre-feasibility level.

A core drilling program of approximately 6,100 metres commenced in November 2011 and is anticipated to be completed in the second quarter of 2012. The objective of the drill program is to define the internal geology of the Mothae kimberlite and extend the currently defined kimberlite volume from a depth of 200 metres to 320 metres.

In the addition, the Company is pleased to announce the appointment of Ms. Jennifer Lecour as Corporate Secretary of Lucara effective December 1, 2011. Jennifer is a lawyer with more than 15 years experience in both the corporate and not-for-profit sector. Jennifer holds both a law degree and degree in psychology from Queen's University. She is also a graduate of the Queen's Executive Leadership Program and a member of the Institute of Corporate Directors.
