growing Clara by adding third party production to the platform and preparing for an

underground expansion at Karowe following the announcement of a positive feasibility study

earlier this month . Anticipated cash flow from operations in 2020 should allow us to pursue

early works which are critical to the underground development schedule, while at the same

time allowing us to leverage our balance sheet to finance th e project in a cost -effective

manner.”

Karowe Mine – Diamond Sales, Production and Cost Outlook for 20 20:

Botswana general & administrative expenses, including

sales and marketing expenses, per tonne processed

$3.00 to $4.00

Tax rate 22%

Average exchange rate – USD/Pula 10.5

Diamond Revenue

In 20 20, the Company forecasts revenues between $1 80 million and $2 10 million, as the

proportion of carats recovered from the higher grade MP/KS and EM/PK(S) units increases.

These projections include “Specials” which are diamonds that are 10.8 carats and larger but

exclude the sale of any truly unique diamonds such as the 1,109 carat Lesedi la Rona and the

813 carat Constellation. Specials are consistently recovered from the Karowe diamond mine

and contribute a significant percentage of the Company’s annual revenue. Diamonds

recovered are expected to be between 370,000 carats and 410,000 carats and diamonds sold

are expected to be between 350,000 carats and 390,000 carats.

Production Estimates and Costs

The Company expects to mine between 3.5 million to 3.9 million tonnes of ore and between 3.6

and 4.2 million tonnes of waste. The 2020 estimated cash cost per tonne of ore processed is

expected to be between $32.00 and $3 6.00. The cost per tonne mined is expected to be

between $4.40 and $4.90 and the estimated processing cost per tonne processed is expected

to be between $ 11.50 and $ 12.50, a reflection of optimization work and strong operation

performance in the plant.

Tax Rates

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

operating costs, including capital e xpenditures, in the year in which they are incurred. Based

on 2019 revenue guidance of $180 million to $210 million the expected tax rate is 22% for 2020

but could decrease depending on the amount and timing of capital expenditures during the

year.

Underground Development Project

A budget of up to $ 53 million has been approved for early works related to a proposed

underground mine at the Karowe Diamond Mine. An investment decision, subject to receipt of

all required authorizations and the arrangement of financing, is expected in H2 2020. Following

the positive results of a feasibility study announced on November 4, 2019 and based on the

Company’s ability to fund these initial capital expenditures from operating cash flow a program

of early works, including detailed engineering and design work has been approved to mitigate

key risks related to schedule.

Sustaining Capital, Maintenance Projects and Community Investment

Sustaining capital and project expenditures are expected to be up to $ 25.0 million in 20 20,

including expenditures associated with the construction of an additional slimes dam (this is a

multi-year project) , upgrades to the XRT recovery circuit and a provision for the

implementation of body scanning technology to enhance sec urity which had originally been

planned for 20 19, subject to receipt of the regulatory approval . In addition, Lucara has

committed to several community investments and optimization initiatives in 2020.

Clara Digital Sales Platform

Following an inaugural diamond sale in December 2018 through Clara Diamond Solutions, its

100% owned digital sales platform , diamond sales through Clara were held with increasing

frequency during 2019 and the customer base increased to 27 participants. Further growth is

expected through 2020 as more supply is made available through the platform, balanced with

demand from the customers using the platform . Third-party production should complement

the diamonds from Karowe which are sold through the platform and should support increased

transaction volumes through 2020.
