VANCOUVER, BRITISH COLUMBIA–(Marketwired – March 6, 2017) – Lucara Diamond Corp. (“Lucara” or the “Company”) (TSX:LUC)(BOTSWANA:LUC)(NASDAQ OMX Stockholm:LUC), is pleased to announce the results of the second BK02 mini-bulk sample and provide an update on other exploration activities.
A total of 309.79 carats were recovered from the processing of 5,021 tonnes of BK02-2, for a sample grade of 6.2 cpht (carats per hundred tonne). The largest diamond recovered was a 4.56 white/grey octahedron. A total of 22 stones were recovered greater than 1 carat in weight, including 5 diamonds in excess of 2 carats in weight (inclusive of the 4.56 carat diamond). The sample was collected from the same location as the results announced on 13 June 2015, after a drill and blast sample was taken to deepen the sample pit, followed by excavation and trucking to the Karowe Mine where processing was conducted through a 15 tonne per hour Bulk Sample Dense Media and X-ray Recovery Plant.
Diamonds were exported to the Lucara Sales and Sorting office for final cleaning and sizing. The second phase sample results confirm the coarse size distribution of the BK02-1 sample.

Three largest diamonds recovered, 4.56, 2.71, 2.26 carats
The combined BK02-1 and BK02-2 samples are presented in Table 2, a total of 584.12 carats have been recovered from 10,937 tonnes of kimberlite for a sample grade of 5.3 cpht. A total of 46 diamonds have been recovered greater than 1 carat in weight, including 8 diamonds greater than 2 carats in weight.

Three largest diamonds recovered, 5.48, 4.56, 2.71 carats
The diamonds recovered are scheduled to be independently valued early in the second quarter of 2017.
A large diameter drill (LDD) program at BK02 is in the advanced planning stage, with the tendering process underway with first material from the pilot drilling program expected in Q2 2017.
A total of 17 drill holes totalling 1,990 metres were drilled into the BK02 kimberlite during 2016 and Q1 2017. A total of 1059 metres of kimberlite were intersected with the deepest intersection of 201m in a vertical PQ diamond drill hole, drilled adjacent to the surface mini-bulk sample excavation. The interpreted surface are of BK02 is 2.1 hectares and additional delineation drilling is planned prior to the commencement of the LDD program.
William Lamb, President and CEO, commented, “Results of the second BK02 mini bulk sample are very encouraging with the improvement in the grade and confirmation of the coarse nature of the BK02 diamond size distribution. The combined parcel of diamonds is suitable for a preliminary diamond valuation which we expect to provide to the market in the second quarter of 2017. The next stage of exploration at BK02 will be to develop an understanding of the diamond content and size distribution continuity at depth.”
AK06 Deep Drilling Program
A deep drilling program at the Karowe Mine AK06 kimberlite was completed in Q1 2017. A total of 12 drillholes (9,750 metres) were completed with approximately 2,770 linear metres within the South Lobe of the AK6 kimberlite being drilled. The program was designed to increase confidence in the geological model for the South Lobe of the AK06 kimberlite and provide sufficient data and material for an updated resource to be utilised in an underground option study for the Karowe mine. Core logging and interpretation is ongoing. Mineral Services Canada has been contracted to aid in the development of a sampling program and internal geology updates that will be utilised for an updated resource estimation for the current inferred portion of the Karowe Mine.
AK11 and AK13 Exploration Update
During Q3 2016 a drill program was initiated and completed at AK11 with a total of 10 core holes (1,570 metres) being drilled. A total of 914m of kimberlite was intersected in the nine holes which were drilled into AK11. Kimberlite was intersected in all of the nine holes drilled. The deepest intersection was 205 metres in a vertical PQ hole drilled into the centre of the AK11 geophysical anomaly. The tenth hole, which did not intersect kimberlite, tested a geophysical anomaly to the west of AK11. Preliminary core logging indicates that AK11 has two distinct pipe infill sequences, a well preserved crater infill (graded bedding, re-sedimented kimberlite), and a more magmatic/pyroclastic kimberlite phase. Drilling confirmed the size of AK11 at approximately 2.5 hectares. Logging and sampling of the drill core is underway, microdiamond samples (1,287 kilograms) are currently being processed and results will be released when the program is complete.
During Q1 2017 a drill program was completed at AK13. A total of 6 holes (756 metres drilling) tested a 150 metre strike length of a vertical kimberlite dyke system, 5 holes intersected kimberlite with 3 holes intersecting wider intercepts of kimberlite, a additional 3 holes tested geophysical anomalies adjacent to AK13 with no kimberlite being intersected. A SE-plunging blow along the AK13 (50 degree plunge on 145 degree azimuth) dyke was identified with a maximum dimension of 130 by 30 metres. The deepest kimberlite intersection is 120 metres vertical. Further drilling is dependant on results of microdiamond samples. Microdiamond samples will be submitted during Q2 2017 and results announced when the program is complete. Drilling is planned to start at AK14 during late Q1 2017.
