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.


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 2026 when the mine transitions to underground. Ore 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.


In 2023, capital costs for the underground expansion are expected to be up to $105 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.  


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 2023 revenue guidance of $200 million to $230 million and assuming the underground development expenditures of $105 million, the tax rate is expected to be 0% for 2023.


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.

On behalf of the Board,

Eira Thomas
President and Chief Executive Officer
