NEWS RELEASE

LUCARA ANNOUNCES THIRD QUARTER 2018 RESULTS

November 8, 2018 Vancouver, British Columbia (LUC – TSX, LUC – BSE, LUC – Nasdaq Stockholm) Lucara

Diamond Corp. (“Lucara” or the “Company”) today reports its results for the quarter ended September 30,

2018.

HIGHLIGHTS FOR THE THIRD QUARTER ENDED SEPTEMBER 30, 2018

(All amounts are presented in USD)

• Karowe’s overall performance with respect to ore and waste mined, ore processed and carats

recovered was within forecast for the third quarter ended September 30, 2018:

o Ore and waste mined was 1.2 million tonnes and 3.9 million tonnes respectively

o Ore processed totaled 0.73 million tonnes with a record 0.26 million tonnes processed in the

month of September 2018

o 197 specials (single diamonds larger than 10.8 carats) were recovered during the third quarter,

representing 4.7% weight percentage of total recovered carats , in line with expectations; 10

diamonds were recovered greater than 100 carats in weight

• Commercialization efforts at Clara are tracking according to budget and plan with inaugural sales

expected to commence in November

• Quarterly sales revenue of $45.7 million (Q3 2017: $77.9 million) or $450 per carat (Q3 2017: $1,161

per carat) recognized during the quarter. This revenue includes proceeds of $3.9 million received in

July 2018 related to the Company’s June tender. Third quarter sales from 2017 included the sale of

the Lesedi La Rona (“LLR”) for $53 million ($4 7,777 per carat), adjusting for the sale of the LLR, the

Q3 2017 average sales price was $389 per carat.

• The operating cash cost for the nine months ended September 30, 2018 was $41.20 per tonne

processed (2017: $32.40 per tonne processed) compared to the full year forecast cash cost of $38 -

$42 per tonne processed. Year to date operating cash cost per tonne processed was impacted by

higher than expected tonnes mined and processed, and an increase in the cost per tonne mined

due to the mining contractor tra nsition which commenced mid -year. Forecast costs for the 2018

fiscal year are still expected to be within guidance.

• Q3 2018 EBITDA of $18.2 million (Q3 2017: $49.8 million) reflects lower revenues attributable to a

smaller volume and lower average price of exceptional stones sold, as compared to Q3 2017 which

included the sale of the 1,109 carat LLR.

• Net income for the three months ended September 30, 2018 was $5.1 million ($0.01 per share) as

compared to net income of $32.9 million ($0.09 per share) in the comparative quarter of 2017.

• As at September 30, 2018, the Company had cash and cash equivalents of $31.1 million. The $50

million credit facility remains undrawn on September 30, 2018.

• 2018 guidance has been increased for tonnes of ore mined and carats recovered; the remainder of

the Company’s guidance remains unchanged for 2018.

Eira Thomas, President and CEO, commented: “Third quarter operational performance at Karowe exceeded

expectations with respect to ore mined and carats produced, and r eflects a seamless transition, three

2

months ahead of schedule, to our new mining contractor, Trollope Mining Services. In parallel, we saw

higher asset availability and record utilization rates for the process plant , positively impacting carat

recoveries.

Growth initiatives, focused on Clara and the Karowe underground expansion opportunity , also continued

to pick up momentum during the quarter. Clara commercialization efforts are now complete, and we are

pleased to be moving forward with our inaugural diamond sale later this month. Clara is the world’s first

secure, digital rough diamond sales platform to sell diamonds individually, based on a customer’s specific

demand, and is positioned to completely transform the diamond sales process, creating efficiencies and

unlocking significant value for producers and manufacturers alike.”

1Average price per carat sold, operating expenses per carat sold and operating margin per carat sold are Non-IFRS measures.

The Company achieved revenues of $45.7 million or $450 per carat for its sales in the third quarter, yielding

an operating margin of 59% during the period. Included in the Q3 2018 revenue are pr oceeds of $3.9

million from the June RST which were received in July 2018. The third quarter of 2018 saw Lucara host its

first blended tender process in which both regular and exceptional diamonds, recovered in the period May-

August, were sold achieving a n average price per carat of $467 from the sale of 89,461 carats (Q3 2017:

64,289 carats), a 39% increase in the number of carats sold as compared to the same quarter last year.

Overall lower revenues reflect natural variability in the number and quality o f exceptional diamonds

recovered in any quarter. Lucara sold the LLR during the third quarter of 2017 recognizing revenue of $53

million ($47,777 per carat). Adjusting for the sale of the LLR, the Q3 2017 average price per carat sold was

$389.

The increase in the number of carats available for sale in the September tender follows commissioning of

the sub-middles circuit in Q3 2017 and increased efficiency in diamond recovery in the smaller sizes during

2018. The number of carats recovered in Q3 2018 (127,031 carats) was more than double the number of

carats recovered in Q3 2017 (62,425 carats). In Q3, Lucara also began setting aside diamonds in the one to

fifteen carat size range in the better colors and qualities , for sale on Clara, Lucara’s secure di gital rough

diamond sales platform. The removal of these diamonds from traditional tender sales will have an impact

on the overall achieved average sales price, however, these differences will be captured and reconciled in

the results reported through Clara. The inaugural sale on Clara is planned and tracking on schedule to take

place later in November, 2018.

Operating expenses increased from $15.4 million in Q3 2017 to $18.8 million in Q3 2018 due to a

combination of higher volumes of ore mined and processed and an increase in the average cost per tonne

mined resulting from the transition between mining contractors during the third quarter.

3

Revenue, EBITDA and earnings per share performance were as expected and reflect the overall timing of

the Company’s sales tenders and its transition to a blended sales tender process in September 2018.

Proceeds of $3.9 mil lion from the June sale were received in July 2018. The Company expects its 2018

revenue to be between $180 million and $190 million (2018 guidance: $170 million to $200 million).

RESULTS OF OPERATIONS – KAROWE MINE, BOTSWANA

THIRD QUARTER OVERVIEW – OPERATIONS – KAROWE MINE

Safety: Karowe had no lost time injuries during the three months ended September 30, 2018 resulting in a

twelve-month rolling Lost Time Injuries Frequency Rate (“LTIFR”) of 0.

During the quarter, Lucara worked cooperatively with Aveng Moolmans and Trollope Mining Services Pty

(“Trollope”) to implement a transition of all mining services to Trollope. August was the first month in which

Trollope was responsible for all waste and ore mining. Performance improved considerably through the

third quarter and has continued. Given the improved performance realized during this period, waste mining

is still expected to be within guidance (13.0 to 16.0 million tonnes) for the year. A change in the mine plan

following the Mineral Resource update mid-year has resulted in a larger volume of ore mined than originally

anticipated. The additional ore results from waste mining in the north lobe. This ore is lower-grade and has

been stockpiled for processing at a later date.

Karowe’s operating cash cost: Karowe’s year to date operating cash cost (see page 11 Non -IFRS

measures) was $41.20 per tonne processed (2017: $32.40 per tonne processed) compared to the full year

forecast of $38-$42 per tonne processed. The increase in cost per tonne processed compared to the nine

months ended September 30, 2017 reflects an increase in year -to-date tonnes mined (2018: 14,808,317

tonnes mined vs. 2017: 12,069,815 tonnes mined) and an increase in tonnes processed (2018: 2,026,672

tonnes processed vs. 2017: 1,703,773 tonnes processed), combined with an increase in the cost per tonne

mined due to the mining contractor transition which commenced mid -year. Forecast costs for the 2018

fiscal year are still expected to be within guidance, albeit at the higher end.

Labour relations update: In July, the Botswana Mine Workers Union notified Karowe management that a

sufficient number of eligible Karowe employees had been recruited to join the union, thereby requiring the

employer to recognize the union pursuant to Section 48 of the Trade Unions & Employers’ Organizations’

Act in Botswana. In Botswana, a majority of currently operating m ines are unionized. During the third

quarter, a number of meetings and joint training between the union and Karowe management have taken

place and an experienced facilitator was appointed. Next steps will include a Memorandum of Agreement

which will govern the working relationship between the two parties, followed by negotiation of a collective

agreement in 2019.

MINERAL RESOURCE UPDATE AND BOTSWANA EXPLORATION

Karowe Resource (AK06 kimberlite) Update

During Q2 2018, an updated mineral resource was announced for the AK06 kimberlite. The updated Mineral

Resource Estimate was completed by Mineral Services Canada Inc. The estimate is based on historical

evaluation data combined with new sampling results (m icrodiamond, bulk density and petrography) from

recent deep core drilling and from historical drill cores. New delineation drill coverage and review of

historical drill cores supported an update of the internal geological model. Production data (including a

controlled production run from the Eastern magmatic/pyroclastic kimberlite ((“EM/PK(S)”) unit) and recent

sales / valuation results have been incorporated into the grade and value estimates, which have been made

based on an updated model of process plant recovery efficiency. The updated Mineral Resource is reported

based on the Canadian Institute of Mining Definition Standards for Mineral Resources and Reserves as

incorporated by National Instrument 43-101 Standards of Disclosure for Mineral Projects.

The updated Mineral Resource, valid at the cut -off date of December 26, 2017, includes a recoverable

Indicated Mineral Resource at a 1.25 mm bottom cut off size of 7.9 million carats hosted in 57.85 million

tonnes at an average grade of 13.7 cpht with an av erage modeled diamond value of $673 per carat. The

new base of the Indicated Mineral Resource is 400 metres above sea level (“masl”) (600 metres below

surface). The updated Mineral Resource also includes a n Inferred Mineral Resource of approximately 1.17

million carats hosted in 5.84 million tonnes at an average grade of 20 cpht with an average modeled

diamond value of $716 per carat between 400 masl to 256 masl (base of current geological and resource

model).

During Q3 2018, an updated Open Pit Mineral Re serve was declared and a National Instrument 43 -101

Technical Report was filed on the SEDAR website (www.sedar.com). The in situ Mineral Reserve for AK06

5

with an effective date of May 25, 2018 is within the probable category containing 19.84 Million tonnes with

a recoverable grade of 13.08 carats per hundred tonne for 2.60 Million carats with an average price per

carat of $ 624/ct. Life of Mine and Working stockpiles contribute an additional 5.56 Million tonnes with a

recoverable grade of 6.7 carats per hundred tonne with an average price of $625/ct. The recoverable grade

is based on the updated Mineral Resource estimate as presented in the technical report (1.25 mm bottom

cut off size - BCOS) at 70% of in situ carats at 1.00 mm bottom cut off size.

These new results are being used for mine planning and to support the preparation of current feasibility -

level studies for the potential development of an underground mine, after the completion of the current

open pit mine.

Botswana Prospecting Licenses:

In 2014, the Company was awarded two precious stone prospecting licenses (PL367/2014 and PL371/2014).

The prospecting licenses are located within a distance of 15 km and 30 km from the Karowe Diamond mine.

The BK02 license was relinquished in Q3 2018 and the AK11/24 license was reduced by 50% in area and

extended for two periods until the third quarter of 2019.

AK11 & AK24

For AK11 during the third quarter, the Company completed processing of the large diameter drilling (“LDD”)

sample (estimated in-situ tonnage of 490 tonnes) at the Company’s Bulk Sample Plant located at the Karowe

Mine. No diamonds were recovered during processing and no further work will be conducted at AK11. At

AK24, four holes were sampled for microdi amonds and samples were shipped to the Saskatchewan

Research Council. Microdiamond results are expected in early Q4 2018.

Sunbird Exploration Generative Project:

During Q2 2018, an agreement was signed with a Botswana company to focus on new kimberlite discoveries

within Botswana using a proprietary UAV magnetometer platform to identify potential targets. Data

acquisition commenced during Q2 2018 and continued through Q3 2018 with the drilling of selected targets

commencing in late Q3 2018. This work is being funded from the original exploration budget of $6.0 million

for fiscal 2018.

2018 OUTLOOK

This section of the MD&A provides management's production and cost estimates for 2018. These are

“forward-looking statements” and subject to the cautionary note regarding the risks associated with

forward-looking statements.

The Company is increasing its 2018 forecast for ore mined from 2.5 – 2.8 million tonnes to 2.9 – 3.1 million

tonnes. The 2018 mine plan was amended following the Mineral Reserve update mid -year and additional,

lower-grade ore has been mined and stock piled. The Company is also increasing the 2018 forecast for

diamonds recovered and sold, from 270,000 – 290,000 carats to 325,000 – 350,000 carats. This i ncrease is

due to better plant performance resulting in a higher recovery of smaller diamonds, which do not contribute

materially to the Company’s revenue. Despite the increase in carats recovered, revenue is expected to be in

the range of $180 - $190 million (2018 guidance: $170 – $200 million). The remainder of the Company’s

2018 forecast remains unchanged as of September 30, 2018.

(1) Operating cash costs are a non-IFRS measure.

(2) Includes ore and waste mined cash costs of $2.90 to $3.20; processing cash costs of $13.75 to $15.00 and mine-site departmental

costs (security, technical services, mine planning, health & safety, geology) of $4.50 to $5.50 (all dollar figures in per tonne mined or

processed).

During 2018, efforts to fully gain access to the Cut 2 South lobe ore require a large volume of waste to be

mined which impacts operating cash costs. The strip ratio is forecast to be approximately 5.0 -6.0 in 2018;

the average strip ratio during the nine months ended September 30, 201 8 was 4.81 and capitalized

production stripping costs totaled $16.7 million.

Sustaining capital expenditures in 2018 are forecast to be up to $11 million, which includes final

expenditures for the sub -middles XRT project audit facility (completed during the three months ending

March 31, 2018). As of September 30, 2018, a total of $9.2 million had been incurred.

A budget of up to $3.0 million was approved for the completion of a pre -feasibility level study (“PFS”) of

the Karowe AK06 underground developme nt. In support of this study, geotechnical and hydrogeological

drilling under a budget of $26 million was initiated and as of September 30, 2018, a total of $15.6 million

had been incurred. In addition, the Company completed and reported an updated miner al resource

estimate on June 26, 2018, re -classifying Inferred Resources within the AK06 kimberlite from 600 to 400

masl to Indicated Resources. It was subsequently determined that the updated 2018 resource in conjunction

with the currently budgeted work p rograms are sufficiently detailed to support conversion of the PFS to a

feasibility study (“FS”), which is now underway and expected to complete in H2 2019. The geotechnical

drilling program is 66% complete with approximately 15,000 metres of drilling undertaken to the end of Q3

2018. Detailed geotechnical and geological logging and sampling is continuing and an update on progress

and results will be reported before the end of the year.

The Company also budgeted $6.0 million for advanced exploration work o n the Company’s prospecting

licenses in Botswana, of which $2.6 million had been incurred as of September 30, 2018. Please see “Mineral

Resource Update and Botswana Exploration” above.
