VANCOUVER, BRITISH COLUMBIA--(Marketwire - March 21, 2013) - Lucara Diamond Corp. (TSX:LUC)(BOTSWANA:LUC)(NASDAQ OMX First North:LUC) ("Lucara" or the "Company") today reports its fourth quarter 2012 results.

William Lamb, President and Chief Executive Officer commented, "2012 was a transformational year for Lucara, having successfully built and commissioned the Karowe Diamond Mine in Botswana safely, on schedule and on budget. During the year, Karowe produced a total of 303,000 carats from 1.4 million tonnes of ore, exceeding guidance by 12%. Proceeds from the sale of nearly 216,000 carats totaled $55 million resulting in an average sales price of $253 per carat, which exceeded our mid-year expectations. In under eight months, Karowe has established itself as one of Botswana's premier diamond producers, having yielded a number of exceptional, high value stones including a 9.6 carat blue diamond that sold for $4.5 million in Q3 and more recently, a 239 carat white diamond that was recovered in early March, 2013. The latter stone represents one of the largest diamonds ever recovered in the prolific Orapa district.

With the successful sales and recovery of exceptional stones continuing in Q1 2013, significant cash proceeds of $32.5 million have been achieved, including the sale of Karowe's second blue diamond for $1.6 million or $341,416 per carat. This cash generation will allow the Company to readily make its first debenture payment instalment at the end of March. I look forward to 2013 being another outstanding year for Lucara."

2013 Corporate Update

• During the first quarter of 2013 the Company sold 144,712 carats of Karowe diamonds for gross proceeds of $32.5 million. The 2013 sales included six parcels totalling 18,233 carats, which were withheld from the December 2012 sale due to low volumes of competitive bidding. Excluding the December diamond inventory sold in January, the average sales price for full 2013 production sold was $243 per carat.
• The Company sold its second blue stone, a 4.77 carat diamond in its March sale for $1.6 million or $341,416 per carat.
• The Company recovered a 239.2 carat diamond from its Karowe mine in Botswana which will be sold on tender during May 2013. In addition to the recovery of this exceptional gem, two more large stones weighing 124.0 carats and 71.1 carats have also been recovered.
• Proceeds of $0.9 million were received in February 2013 from the sale of some 2,100 carats of diamond, which remained from Mothae's trial mining program.

During 2012 the Company commenced production and declared commercial production at Karowe as at July 1, 2012. As a result, diamonds produced and sold post July 1, 2012 are recognized as revenue in the Company's consolidated statements of operations. The Company excluded Karowe's June, July and a portion of the September sales totalling 63,038 carats for proceeds of $12.8 million and related operating expenses and royalty expenses. These sales have not been included in the consolidated statement of operations and therefore gross margin and EBITDA for the year. The gross margin from these sales has been credited against capitalized plant and equipment. As a result, full year 2012 sales of $41.8 million are reported in the Company's accounts with total proceeds of $54.6 million being received.

OPERATIONAL RESULTS:

Karowe Mine - Botswana (formerly AK6 Diamond Project)

• There were no Lost Time Injuries ("LTI's") or reportable environmental incidents at Karowe during the year continuing its excellent safety, health and environment record. There have been over 2.9 million hours worked without any LTI's since March 2011, including 1.8 million hours since the beginning of 2012. Karowe's Lost Time Injuries Frequency Rate ("LTIFR") was zero for 2012. LTIFR is defined as the total number of work hours lost per 200,000 work hours.
• Commissioning and production ramp-up activities to achieve sustainable production were completed in the third quarter. Ramp-up to full production capacity, which commenced in April, was achieved by August.
• During the fourth quarter, the mine treated 545,354 tonnes compared to a forecast of 538,242 tonnes, producing 138,487 carats against a forecast of 108,981 carats. During 2012, the mine treated 1.4 million tonnes, 9% above the forecast of 1.27 million tonnes, producing 303,000 carats, which was 12% above the forecast of 271,000 carats. The average recovered grade during the fourth quarter was 25.4 carats per hundred tonnes. The average recovered grade for 2012 was 22.0 carats per hundred tonnes.

Mothae Project - Lesotho

• The trial mining program was completed in September with final processing of hard, unweathered kimberlite from the central resource domain of the south lobe of the Mothae kimberlite. This brings the total tonnage sampled from the Mothae kimberlite for economic evaluation purposes to 603,819 dry tonnes yielding an average sample grade of 3.88 carats per hundred tonnes ("cpht").
• In the fourth quarter of 2012, the x-ray recovery tailings audit of all recovery tailings was completed. The project is now fully transitioned to a small care and maintenance team.

Revenues

During the year the Company had five sales totalling 215,762 carats for gross proceeds of $54.6 million at an average price of $253 per carat. Included in these results is the sale of a 9.46 carat blue diamond for $4.5 million or $477,272 per carat. Gross revenues reported for the year were $41.8 million, which included post commercial production of 51,737 carats from the September sale and 100,987 carats from the November and December sale.

Cash operating earnings

Cash operating earnings for the year was $23.6 million. This reflects a $274 per carat price received for diamonds sold in September through December net of royalties of 10% and operating expenses of $92 per carat sold.

Cash operating earnings of $23.6 million result in a gross margin of 56% on sales. The average grade for the year was 22.0 carats per hundred tonnes.

Cash operating earnings is a non-GAAP measure and is reconciled in the table above.

Exploration expenditures

The exploration expenditures relate primarily to the on-going trial mining program, which commenced in May 2010 at Mothae, offset in part by the value of diamonds recovered and sold, based on management's best estimate of the value of the diamonds at the time of recovery. The difference between the carrying value and the subsequent proceeds from the sale of diamonds is treated as a gain or loss as it is a change in market conditions during the period.

Exploration expenditures were $12.9 million during the year compared to $6.6 million in 2011. The difference largely relates to decreased diamond recoveries during the year as harder material was processed at a slower rate, costs relating to work on Mothae's preliminary economic assessment and further costs for non-recurring care and maintenance activities.

The expenditures in 2012 have been partially mitigated by the earnings from Mothae's sale of 4,657 carats in September yielding gross proceeds of $1.5 million.

Administration expenses

The increase in administration expenses for the year ended December 31, 2012 compared to the prior year is largely due to the payment of performance incentive bonuses to key employees of the Company and other non-recurring costs.

Earnings before interest, tax, depreciation and amortization (EBITDA)

EBITDA for the year was a loss of $0.2 million. EBITDA was impacted by:

• Exclusion of Karowe's June, July and a portion of the September sale totalling 63,038 carats for proceeds of $12.8 million and related operating expenses and royalty expenses. These sales have not been included in the consolidated statement of operations and therefore gross margin and EBITDA for the year. The gross margin from these sales has been credited against capitalized plant and equipment. As a result, full year 2012 sales of $41.8 million are reported in the Company's accounts with total proceeds of $54.6 million being received.
• Exploration expenditures of $12.9 million at Mothae were due to its trial mining program and costs incurred for its preliminary economic assessment. Mothae has now been placed on temporary care and maintenance with limited operating expenditure going forward as the Company reviews a number of development options for the asset.
• Higher administration costs during the period due to some non-recurring costs.

LIQUIDITY AND CAPITAL RESOURCES

As at December 31, 2012, the Company had cash and cash equivalents of $13.3 million compared to cash and cash equivalents of $48.6 million at December 31, 2011.

Cash generated from operating activities before working capital movements for the year ended December 31, 2012 was an inflow of $3.8 million. This includes Karowe sales from September to December with cash operating earnings of $23.6 million as well as Mothae's September sale for proceeds of $1.5 million. These proceeds were offset by Mothae's exploration costs to complete its trial mining program and work on the preliminary economic assessment as well as corporate costs. The June, July and a portion of the September sale with proceeds of $12.8 million have been included as part of investing activities and not operating cash flows as these sales included pre-commercial production and was reported net of costs in capitalized plant and equipment.

In April the Company signed a definitive agreement with the Bank of Nova Scotia for a $25 million revolving term credit facility with a maturity date of March 26, 2014, which may be extended if both parties agree.

The facility contains financial and non-financial covenants customary for a facility of this size and nature. As at December 31, 2012, the Company is in compliance with all financial and non-financial covenants The applicable interest rate of any loan under the facility will be determined by the Company's leverage ratio at any given time. The Company has provided security on the two year facility by way of a charge over the Company's Karowe assets and a guarantee by the Company's subsidiaries, which hold the Karowe assets. As at December 31, 2012 the Company had drawn $4.5 million of the credit facility.

Net cash from financing activities for the year ended December 31, 2012 included a $9.5 million drawdown and a $5 million repayment on the Scotiabank credit facility.

The Company has entered into foreign currency contracts totalling $8.0 million as at December 31, 2012 to help manage the uncertainty of foreign exchange fluctuations in the market. The contracts mature in March 2013 and May 2013. They are at an average rate of Botwana Pula 7.8244 per $1.00. Subsequent to December 31, 2012, the Company entered into a series of forward exchange contracts to fix the rate at which future anticipated cash flows in U.S. dollars are exchanged in Botswana Pula. Such contracts include forward sales of U.S. dollars at an average rate of 7.9581, in the aggregate amount of $43.3 million from February 2013 to December 2013. As a result, the Company's outstanding forward exchange contracts totalled $51.4 million at an average rate of 7.9369.
