NEWS RELEASE

LUCARA’S Q1 2022 REVENUE OF $68.2 MILLION REFLECTIVE OF A STRONG START TO 2022

VANCOUVER, May 5, 2022 /CNW/ (LUC – TSX, LUC – BSE, LUC – Nasdaq Stockholm)

Lucara Diamond Corp. (“Lucara” or the “Company”) today reports its results for the quarter ended March 31, 2022.

Q1 2022 HIGHLIGHTS:

• Revenue in Q1 2022 increased by 28% to $68.2 million from $53.1 million in Q1 2021 a reflection of strong

rough and polished diamond market fundamentals into the first quarter.

• The combination of a strong diamond market, combined with the sale of several higher value rough

diamonds in Q1 2022 generated an average price per carat (excluding top-up payments) of $690 for Karowe

diamonds sold during the quarter (Q1 2021: $480 per carat).

• A total of 186 Specials (single diamonds in excess of 10.8 carats) were recovered, representing 6.9% weight

percent Specials (Q1 2021: 6.8%).

• Sales volumes transacted on Clara during Q1 2022 totalled $7.0 million, a 17% increase from the $6.0 million

in sales volume transacted in Q1 2021. A third-party producer will commence a series of trial sales beginning

in Q2 of 2022.

• A total project investment of $31.1 million into the Karowe UGP during Q1 2022 focused on shaft pre-sinking

activities and construction of a new 29km 132kV transmission line.

Eira Thomas, President & CEO comm ented: “Lucara begins the year on a positive trajectory, having fully financed

and significantly de-risked our growth plans for the underground expansion in 2021 and delivered another strong

quarter of operating and financial results in Q1, reflecting solid performance at the mine combined with continued

buoyancy in diamond prices. Preparation for main shaft sinking is well underway and anticipated to begin in Q2. Our

multi-channel approach to sales through tenders, Clara and HB continues to mature, creating alignment along the

value chain, delivering efficiencies and higher margins. Despite current geo -political challenges, Lucara r emains

optimistic about diamond prices as natural rough diamond supply constraints continue to manifest globally. ”

REVIEW FOR THE QUARTER ENDED MARCH 31, 2022

• Operational highlights from the Karowe Mine for the three months ended March 31, 2022 included:

o Mined 0.8 million tonnes (Q1 2021: 1.0) and 0.5 million (Q1 2021: 0.8) of ore and waste, respectively.

o Processed 0.7 million tonnes of ore (Q1 2021: 0.7) and r ecovered 83,917 carats (Q1 2021: 80,014

carats), achieving a recovered grade of 12.6 carats per hundred tonnes (Q1 2021: 11.9 cpht).

o A total of 10 diamonds greater than 100 carats were recovered during the quarter.

o Total Recordable Injury Frequency Rate ( "TRIFR") of 0. 23 in Q1 2022 reflects one medical treatment

case reported (Q1 2021: zero).

2

• Financial highlights for the three months ended March 31, 2022 included:

o Revenues from the sale of 80,295 carats recovered from the Karowe Mine were $67.2 million (Q1

2021: $53.0 million from the sale of 91,734 carats from Karowe). The sales agreement with HB Trading

BV (“HB”) accounted for 66% (Q1 2021: 72%) of total revenues recognized in the quarter.

o Operating cash costs of $29.30 per tonne processed (1) (Q1 2021: $29.24 per tonne processed)

remained consistent with the comparative period. Q1 2022 costs are inclusive of the impact of higher

power, labour and insurance costs, partially offset by a comparatively stronger U.S. Dollar.

o Adjusted EBITDA(1) of $36.0 million increased by 62% from $ 22.2 million for the same period in 2021,

attributed primarily to higher revenues.

o Net income for the quarter increased to $19.0 million ($0.04 basic earnings per share) from $3.4

million ($0.01 basic earnings per share) in Q1 2021.

(1) Operating cash cost per tonne processed and adjusted EBITDA are non -IFRS measures (See “Use of Non -IFRS

Financial Performance Measures”).

• Cash position and liquidity:

o As at March 31, 2022, the Company had cash and cash equivalents of $39.1 million.

o The Company drew an additional $20. 0 million from the $170.0 million project loan facility in the

quarter for a total drawn amount of $45.0 million.

o Strong cash flow from operations allowed for a reduction to the outstanding balance on the working

capital facility, from $23.0 to $12.0 million as at March 31, 2022.

DIAMOND SALES

Consistent with the Company’s approach through 2021, diamond sales continued to be held through a combination

of regular tenders, and the Clara platform, for diamonds less than 10.8 carats, and through HB under the sales

agreement for those gem and near-gem diamonds greater than 10.8 carats which are to be manufactured and sold

as polished. All other diamonds are sold in quarterly tenders. The Company recognized revenue of $68.2 million in

the first quarter of 2022 from the sale of 80,295 carats from Karowe . This amount included top-up payments of

$11.7 million as well as $1.0 million from the sale of third -party goods on the Clara platform. In comparison, the

Company achieved revenues of $53.1 million from sales of 91,760 carats in the first quarter of 2021 which included

top-up payments of $ 9.1 million as well as $0.1 million in revenue from third -party goods sold through the Clara

platform.

The exceptionally strong performance throughout 2021 was driven by higher diamond prices which were reflective

of the impact of strong demand for both rough and polished diamonds, combined with supply constraints in certain

size classes. This strength continued into Q1 2022. Beginning in Q2 2020, all +10.8 carat diamonds mined from

Karowe were delivered to HB pursuant to the terms of the diamond sales agreeme nt described below.

HB SALES AGREEMENT FOR +10.8 CARAT DIAMOND PRODUCTION FROM KAROWE

Karowe’s large, high value diamonds have historically accounted for approximately 60% to 70% of Lucara’s annual

revenues. In 2020, Lucara announced a partnership agreeme nt with HB, entering into a definitive sales agreement

for diamonds recovered that exceed +10.8 carats from the Company’s 100% owned Karowe Diamond mine in

Botswana. This agreement was subsequently amended and extended to December 31, 2022 . The mechanisms of

the agreement result in complete transparency within the value chain and create important alignment between the

producer and the manufacturer for the first time.

3

Under the amended sales agreement, +10.8 carat gem and near gem diamonds from the Karowe Mine of qualities

that can directly enter the manufacturing stream are being sold to HB at prices based on the estimated polished

outcome of each diamond. The estimated polished v alue is determined through state -of-the-art scanning and

planning technology, with an adjusted amount payable on actual achieved polished sales, less a fee and the cost of

manufacturing. Following the extension of the HB Agreement in 2021, all +10.8 carat non-gem quality diamonds and

all diamonds less than 10.8 carats in weight which did not meet the criteria for sale on Clara are being sold as rough

through the quarterly tender. In the agreement extension, payment terms were amended to better reflect the timing

of mine production and the manufacturing process. This unique pricing mechanism delivers regular cash flow for

this important segment of our production profile.

For the three months ended March 31, 2022, the Company recorded revenue of $45.2 million from the HB

agreement (inclusive of top -up payments of $11. 7 million), as compared to revenue of $38.0 million in Q1 2021

(inclusive of top-up payments of $9.1 million). In Q1 2021, all +10.8 carat stones were sold through HB. Beginning

in April 2021 when the HB agreement was extended, any +10.8 carat stones not earmarked for manufacturing by HB

were sold through the Company’s quarterly tender process. The increase in revenue in Q1 2022 is attributed to

higher prices achieved, despite lower sale volumes. This reflects a significant improvement in diamond market

fundamentals between the two comparative quarters. Due to natural variability in the quality profile of the +10.8ct

production in any production period or fiscal quarter, the recorded revenue and associated top ups will fluctuate.

This is expected and reflects a combination of current diamond market prices as well as variability in the quality of

Karowe’s production profile in any given period.

As a result of the sales agreement with HB, the Company also participated in polished diamond price increases during

Q1 2022 as rough diamonds sold to HB in previous quarters were polished and sold. In Q1 2022, top-up payments

of $11.7 million (Q1 2021: $ 9.1 million) were included in revenue for the quarter . At March 31, 2022 a number of

higher value and more technically complex stones that take longer to manufacture had not fully completed the

manufacturing and sales process. These stones were delivered to HB in 2021 and Q1 2022. As these stones finish

the manufacturing process and are sold, the Company’s may record additional revenue in the form of “top -up”

payments from these sales.

CLARA SALES PLATFORM

Clara, Lucara’s 100% owned proprietary, secure, web -based digital sales platform, continues to gain scale and

interest. Interest in Clara continues to grow as the benefits of purchasing rough diamonds in an innovative way

become evident. In Q1 2022, three sales (Q1 2021: six sales) took place with a total sales volume transacted of $7.0

million, a 17% increase from the $6.0 million transacted in Q1 2021, reflecting a strong upward price trend observed

on Clara during Q1 2022. The number of buyers on the platform increased to 92 at March 31, 2022 with the Company

maintaining a waiting list to manage supply and demand.

While most of the stones transacted through the platform are supplied from the Karowe Mine, secondary market

stones continued to be offere d for sale through the platform with good results. Additional supply is required to

meet existing demand and drive the platform’s growth and the Company expects to commence a series of trial sales

on the Clara platform with a third -party producer in Q2 2022. The Company intends to continue to seek additional

supply in 2022, both from third-party producers and the secondary market.

KAROWE UNDERGROUND EXPANSION UPDATE

The Karowe UGP is expected to extend the mine life to at least 2040, with underground carat production

predominantly from the highest value EM/PK(S) unit and is forecast to contribute approximately $4 billion in

additional revenues, using conservative diamond prices. The Karowe UGP has an estimated $534 million capital cost

and a five -year construction period. Mine ramp up is expected in Q1 2026 with full production from the UGP

expected in H2 2026. The Company is financing the Karowe UGP through a combination of cash flow from operations

and project debt.

4

During the three months ended March 31, 2022, a total of $31.1 million was spent on the Karowe UGP development,

primarily in relation to engineering, procurement of long lead items and ongoing construction activities, including:

• Pre-sink activities for both the production and ventilation shafts continued with a focus on the setup and

transition to main sinking.

• Placement of the ventilation shaft main sinking stage into the shaft column along with placement of the

ventilation shaft headgear over the shaft collar.

• Assembly of the production shaft main sink stage with outfitting planned for Q2 in preparation for its

installation in the shaft column, while pre-assembly of the production shaft headgear steel continued.

• Cold commissioning of the ventilation shaft kibble winder was completed, with progress on the ventilation

shaft stage winder in preparation for winder rope -ups in April, while installation of the production shaft

stage winder commenced.

• Completed construction of all 88 tower foundations for the 29 km 132kV transmiss ion line bulk power

upgrade and commenced construction at both Letlhakane and Karowe substations.

Activities for the UGP in the upcoming quarters of 2022 are expected to include the following:

• Execution of the main sinking contract for the production and ventilation shafts

• Completion of the steel headgear structure for the production and ventilation shafts.

• Commissioning of the four main sinking winders.

• Commencement of main sinking for the production and ventilation shafts.

• Continuation of detailed design and engineering of the underground mine infrastructure and layout.

• Commissioning of the 29 km 132kV bulk power supply powerline by December 2022.

DIAMOND MARKET

A strong rebound in diamond jewelry demand, combined with growing global natural rough diamo nd supply

constraints, contributed to a healthy recovery in diamond prices in 2021. This price strength continued into the first

quarter of 2022 where increases were observed across most sizes, qualities and colors of diamonds.

Current pricing trends have been impacted by uncertainty triggered by geopolitical events, including the conflict in

Ukraine and the COVID-19 pandemic, however, we continue to observe healthy market fundamentals overall, and

our longer-term outlook remains positive for diamond prices. The diamond price impact of sanctions on Russian

diamond supply, which accounts for a significant portion of global reserves, cannot be predicted at this time.

The benefits of the committed sales agreement with HB continued to be realized during the first quarter of 2022 as

the Company participated in polished diamond price increases during Q1 2022 for diamonds delivered in previous

quarters. The integrated approach, using state of the art scanning and planning technology has further enhanced

the final achieved polished outcome for very large (+50 carat polished) and high value diamonds, a critical production

segment for the Company.

2022 OUTLOOK

This section of the press release provides management's production and cost estimates for 2022. These are

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

statements. In February 2022, based on updated expectations for revenue in 2022, the diamond revenue guidance

issued was increased to between $195.0 million and $225.0 million (from $185.0 million to $215.0 million). Diamond

revenue guidance does not include revenue related to the sale of exceptional stones (an individual rough diamond

which sells for more than $10 million), or the Sethunya.

Karowe Diamond Mine Full Year – 2022

Diamond revenue (millions) (revised as of February 2022) $195 to $225

Diamond sales (thousands of carats) 300 to 340

Diamonds recovered (thousands of carats) 300 to 340

Ore tonnes mined (millions) 3.1 to 3.5

Waste tonnes mined (millions) 1.5 to 2.1

Ore tonnes processed (millions) 2.6 to 2.8

Total operating cash costs(1) including waste mined(2) (per tonne processed) $29.50 to $33.50

Botswana general & administrative expenses including marketing costs (per tonne

$3.50 to $4.00

Tax rate(3) 0%

Average exchange rate – USD/Pula 11.0

(1) Operating cash costs are a non-IFRS measure. See “Non-IFRS Financial Performance Measures”.

(2) Includes ore and waste mined cash costs of $5.75 to $6.25 (per tonne mined) and processing cash costs of $12.00 to $13.00 (per tonne

processed).

(3) The Company is subject to a variable tax rate in Botswana based on a profit and revenue ratio which increases as profit as a percentage of

revenue increases. The lowest variable tax rate is 22% while the highest variable tax rate is 55% (only if taxable income wer e equal to

revenue). Capital expenditures are deductible when incurred. With planned capital expenditures of up to $110 million for the UGP, a tax

rate of 0% is forecast for 2022. Should capital expenditures vary from plan, the Company could be subject to current tax.

In 2022, the Company's revenue forecast assumes that 100% of the carats recovered will come from the higher value

M/PK(S) and EM/PK(S) units within the South Lobe in accordance with the mine plan.

The assumptions for carats recovered and sold are consistent with achieved performance in recent years. The

number of tonnes processed is also consistent with recent achievements, noting that actual tonnes processed in

2021 was about 6% higher than 2020 due to improving plant reliability because of the success of the preventative

maintenance plan that has been implemented.

Waste tonnes that were deferred in 2021 as other mining areas in the open -pit were prioritized are expected to be

caught up in between 2022 and 2024. The estimated processing cost per tonne processed is higher than previous

years, reflecting expected inflationary pressure on labour and commodity costs.

In 2022, capital costs for the underground expansion are expected to be up to $110 million and will focus on the

commencement of main shaft sinking activities, the commissioning of the bulk power supply 132 kV line and

substations and detailed engineering for the underground development. Sustaining capital and project expenditures

are expected to be up to $17 million with a focus on completion of a community sports facility, dewatering activities

and an expansion of the tailings storage facility.

Lucara Botswana’s progressive tax rate computation allows for the immediate deduction of operating costs,

including capital expenditures, in the year in which they are incurred. Based on the updated 2022 revenue guidance

of $195 million to $225 million and assuming the underground development expenditures are incurred, the expected

tax rate will be 0% for 2022.
