PRESS RELEASE

LUCARA PROVIDES OPERATIONAL UPDATE AND ANNOUNCES COVID-19 RESPONSE STRATEGY

VANCOUVER, March 31, 2020 /CNW/ - (LUC – TSX, LUC – BSE, LUC – Nasdaq Stockholm)

Lucara Diamond Corp. (“Lucara” or the “Company”) announced today that it has implemented a crisis management

strategy in relation to COVID -19, to protect the health and well -being of its employees in Botswana and Canada.

Lucara’s 100% owned Karowe Diamond Mine, situated in north central Botswana remains full y operational, under

new measures and guidelines implemented by the Government of Botswana (“GRB”) earlier this week. The se

measures include increased travel restrictions, reduced staffing and increase d social distancing pertaining to all

aspects of its business. Employees who are able to work remotely are doing so. As travel restrictions relating to

COVID-19 are expected to remain in place for an unknown period of time, the Company’s ability to complete tenders

in Botswana may be impacted. As a temporary measure, the Government of Botswana has granted Lucara

permission to hold diamond sales in Antwerp, Belgium if required.

Lucara completed its first of four planned diamond tenders for the year on March 5, and achieved sales prices within

1% of forecast, however, diamond prices have since deteriorated in response to weaker demand as COVID -19 has

continued to spread globally. Though Lu cara’s next quarterly tender is not scheduled to take place until mid May

2020, the full impact of COVID-19 on Lucara’s operations and production outlook for 2020 remains highly uncertain,

and as a result, the Company has taken the decision to suspend its 2020 guidance until further notice.

Key Operational Highlights to Date:

• Lucara began the year with a strong balance sheet - cash positive, no debt, and an undrawn US$50mln

working capital facility.

• Lucara is a low volume, high value diamond producer, with 70% of revenues generated from diamonds

in excess of 10.8 carats. Diamond tenders are held quarterly.

• Lucara’s first quarterly diamond tender was completed March 5 achieving sales results within 1% of

forecasted reserve prices; all proceeds from this tender have been received.

• Clara, Lucara’s web based digital sales platform for rough diamonds , which sells diamonds under 10.8

carats in size remains operational.

• Lucara has flexibility and optionality in its capital budget for 2020. Spending on the underground project

is scheduled to ramp up in Q3 but Lucara has the ability to adjust the timing of these expenditures as they

are not currently committed.

Eira Thomas, Lucara’s CEO stated: “Our main focus right now is on the safety and wellbeing of our workforce and

the local communities in which we operate. The global diamond industry is experiencing the widespread impacts of

COVID-19 throughout the value chain, manifested as fewer sales, weaker pricing and production curtailments at

several mines. Though the Karowe diamond mine continues to operate according to plan, and the first quarter 2020

sale achieved results within expectations, the full impact of COVID-19 on our business remains uncertain.

Lucara has worked swiftly to implement a crisis management plan to protect our people and assets, and continues

to monitor this dynamic situation closely, day by day. Lucara began the year with a strong balance sheet, cash on

hand, no long -term debt and flexibility in our 2020 capital spending program. Our longer -term outlook for the

diamond market remains positive, based on improving supply -demand fundamentals that were beginning to

manifest in late 2019, prior to the COVID-19 crisis taking hold. What’s more, diamond sales are continuing through

2

Clara, our secure web based digital sales platform , which has the unique advantage of providing customers with a

forum to buy rough diamonds without the requirement to travel.

In this challenging and volatile time, the quality of our assets combined with the strength of our balance sheet and

the fact that Lucara is not carrying any long -term debt, helps to position the Company to effectively manage the

business through this crisis. We would like to extend our sincere thanks to our employees, shareholders,

stakeholders and communities of interest for their continued support, and, extend our best wishes for good health”.

The Karowe Diamond Mine

During the first quarter of 2020, the Karowe diamond mine continued to operate safely and according to budget and

plan. As part of the Company’s ongoing COVID-19 response plan, management continues to analyze risks in relation

to all aspects of our mining and sales operations and, within our supply chains. At the present time, w e have not

identified any immediate obstacles to the continued, safe operations of our mine and the sales office but we also

acknowledge that the situation is extremely dynamic . Lucara will strictly adhere to the government guidelines and

exercise all precautionary measures it needs to take to keep its employees safe and healthy. These measures include,

but are not restricted to, working from home where possible , reduced overall staffing levels, increased and

appropriate social distancing, and, restrictions on travel. To this end, Lucara’s capital spending program for 2020 is

also being reviewed. The largest component of this year’ s capital spend relates to a US$53mln approved program

for the Karowe underground expansion project, the bulk of which is scheduled to be invested in the latter part of

the year. It is important to note that the underground program and schedule for 2020 retains both optionality and

flexibility as the expenditures scheduled to be incurred are not committed, and, can be adjusted as Lucara’s cashflow

projections and operational capacity become more certain. Further guidance will be provided in advance of the Q1

quarterly earnings call scheduled for Friday, May 8, 2020.

Diamond Tender Completed March 5, 2020

Lucara completed its first diamond tender of the year on March 5 , selling all diamonds recovered and prepared for

sale during the period, and achieved an overall result within 1% of expected reserve prices. Achieved prices were in

line with the pricing environment that prevailed in early-mid 2019 and are consistent with our previously reported

2020 Outlook. These pricing assumptions be adjusted in the coming weeks and months as the full impact of COVID-

19 becomes better understood. We experienced a solid turnout for the sale, with a total of 104 companies attending

in Gaborone and a participation rate of 80%. Our smallest planned sale for the year, t he Q1/20 tender sold 83,610

carats, including 37 single stones greater than 10.8 carats in size. A total of 4 stones were sold for in excess of

US$1mln including 2 that sold for more than US $2mln. All goods prepared for sale were sold. M anagement is

monitoring the travel restrictions related to COVID-19 which may impact Lucara’s ability to complete tenders within

Botswana for a period of time . As a temporary measure, in response to the COVID -19 crisis, the Government of

Botswana has granted Lucara permission to hold diamond sales in Antwerp, Belgium if required.

Clara Sales Continue

CLARA uses technology to create a more efficient, transparent, global marketplace and provides greater connectivity

between the rough and polished diamond marketplaces remotely, from any jurisdiction around the world. Never,

we feel, has this innovation been more relevant or more important. In this current, unprecedented global lockdown,

where personal travel is restricted and diamond tenders and sights are being canceled or postponed, CLARA remains

operational, allowing purchase s of individual diamonds to continu e, providing flexibility and optionality to help

businesses throughout the supply chain be more effective at managing their purchases in response to the current,

dynamic business environment. A total of 6 sales have been transacted on Clara in 2020, with 25 out of 32 total on-

boarded manufacturers participating, the highest participation rate to date. A total of just over 1,800 carats and

3

821 diamonds have been transacted. Though volumes are slightly lower than in previous sales and may continue to

fluctuate, reflective of the more challenging business environment that has emerged, Clara continues to attract

strong interest and participation. We expect this interest t o continue and potentially grow as travel restrictions

persist, respective of the possibility that the transportation of our diamonds may be subjected to delays or other

constraints in relation to the COVID-19 crisis.

On behalf of the Board,
