NEWS RELEASE

LUCARA ANNOUNCES OPERATING GUIDANCE FOR 2023

VANCOUVER, November 28, 2022 /CNW/ (LUC – TSX, LUC – BSE, LUC – Nasdaq Stockholm)

Lucara Diamond Corp. (“Lucara” or the “Company”) is pleased to provide operating guidance for 2023 (all amounts

in USD unless otherwise stated).

2023 OUTLOOK

This section provides management's production and cost estimates for 202 3. These are “forward -looking

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

Karowe Mine (all amounts in US Dollars) Full Year 2023

Diamond revenue $200 million to $230 million

Diamond sales 385,000 carats to 415,000 carats

Diamonds recovered 395,000 carats to 425,000 carats

Tonnes mined – Ore 1.9 million to 2.3 million

Tonnes mined – Waste 2.2 million to 2.8 million

Tonnes processed – Ore 2.6 million to 2.9 million

Total operating cash costs per tonne processed (including (a) to (b) below): $32.50 to $35.50

(a) Cash cost per tonne mined (ore and waste) $7.00 to $8.00

(b) Cash cost per tonne processed $12.00 to $13.00

Botswana G&A expenses, including sales and marketing, per tonne processed $3.50 to $4.50

Tax rate 0%

Average exchange rate – Botswana Pula per United States Dollar 12.0

REVENUE AND SALES CHANNELS

In 2023, the Company’s revenue forecast assumes that 52% of the carats recovered will come from the higher value

M/PK(S) and EM/PK(S) units within the South Lobe and the remaining 48% of the carats recovered will come from

the Centre Lobe in accordance with the mine plan, generating revenue between $ 200 and $230 million in 2022.

Centre Lobe material, while higher grade, has a lower weight percentage of stones greater than 10.8 carats in size

when compared to South Lobe material.

With the recently announced extension of the HB agreement, the Company will continue to use three different sales

channels to maximize revenue and generate consistent cash flow to support the Company’s operations and its

investment in the underground expansion project. Higher value stones greater than +10.8 carats in size will continue

to enter the manufacturing pipeline at HB, giving the Company exposure to polished prices and regular cash flow

from the highest value portion of the Karowe production. Quarterly tenders and regular sales through Clara,

primarily for stones less than 10.8 carats in size will continue, consistent with the practise from previous years.

MINING AND PROCESSING ASSUMPTIONS

In 2023, the Company expects to mine between 4. 1 and 5.1 million tonnes, of which ore tonnes mined represent

approximately half of total tonnes mined. The assumptions for carats recovered and sold as well as the number of

tonnes processed are consistent with achieved performance in recent years. Material from the open pit is planned

to be processed between 2023 to 202 6 when the mine transitions to underground. O re from the underground

development is expected to supplement lower grade stockpile material during the transition to underground at the

end of the open pit mine life.

UNDERGROUND AND SUSTAINING CAPITAL EXPENDITURES

In 2023, capital costs for the underground expansion are expected to be up to $1 05 million and will focus

predominantly on shaft sinking activities, along with construction of the bulk air cooler, tendering the underground

development contract and underground equipment purchases . Ramp-up to planned sinking rates for both the

ventilation and production shaft continues. A complete review of the current program schedule and budget is

underway and will be completed in Q1 2023.

Sustaining capital and project expenditures related to the open pit mining operations are expected to be up to $20

million with a focus on replacement and refurbishment of key asset components in addition to dewatering activities,

an expansion of the tailings storage facility in accordance with Global Industry Standard on Tailings Management

and completion of a community sports facility.

BOTSWANA TAX RATE

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 202 3 revenue guidance of $ 200

million to $2 30 million and assuming th e underground development expenditures of $1 05 million, the tax rate is

expected to be 0% for 2023.

CLARA SALES PLATFORM

Clara, Lucara’s 100% owned proprietary, secure, web -based digital sales platform, continues to grow in terms

of volume transacted and customer participation. Platform trials and discussions with third party suppliers of rough

diamonds are ongoing to build supply, which remains a key objective for 2023 and beyond. The rationale for a web

based digital sales platform for the transaction of rough diamonds has never been stronger, sparked by industry’s

need for increased transparency, global restrictions on travel, and a new openness to the use of innovation and

technology to create a more efficient supply chain.
