Lucara Diamond Corp. ("Lucara" or the "Company") today reports its results for the year and quarter ended December 31, 2022.

FISCAL 2022 HIGHLIGHTS:

• All key operational and financial metrics from the Company's 2022 Guidance were achieved, including 3.3 million tonnes of ore and 1.5 million tonnes of waste mined, and 2.8 million tonnes of ore processed.
• Revenue for the year ended December 31, 2022 totalled $212.9 million, including $9.1 million through Clara.
• A total of 327,028 carats were sold through the Company's three sales channels, generating revenue of $165.4 million before top-up payments of $38.4 million for the year ended December 31, 2022.
• A strong U.S. dollar helped to mitigate increases in input costs, resulting in an operating cash cost of $27.94 per tonne of ore processed⁽¹⁾ for the year ended December 31, 2022.
• Cash flow of $96.2 million from operating activities.
• $35.7 million in sales transacted on Clara, with approximately 40% of sales from third-party goods transacted, reflecting a positive trend towards increased diversification of supply and less reliance on Karowe production.
• $106 million invested in the Karowe underground expansion project ("UGP") during 2022 with a total project to-date investment of $226.1 million. Several significant milestones were achieved in 2022 including:
• Substantial completion of surface civil works, including headgear erection and winder installs on time and within budget.
• Main shaft sink activities started in both the ventilation and production shafts to depths below collar of 179 metres and 132 metres, respectively.
• Commencement of grouting programs in each shaft during December.
• Completion and energization of the bulk power upgrade consisting of a 29km, 132kV power line and the Letlhakane and Karowe substations.
• Procurement of underground mobile equipment and the signing of a contract for construction and supply of a bulk air cooler.

Eira Thomas, President & CEO commented: "The Karowe diamond mine completed its tenth year of continuous operations and successfully delivered on all of its' financial and operating metrics, including safety, production, processing, sales and revenues, with costs trending below guidance and continued access to sufficient liquidity in support of our growth plans. For the underground expansion project, we achieved a number of important milestones, including the completion of all pre-sinking activities on schedule and budget, the execution of a main shaft sinking contract, the commencement of main shaft sinking and the completion of a new power line on schedule and budget.  Importantly, we commenced our first grouting phase in the production shaft in December which was successfully completed in February 2023, confirming that our planned approach and methodology is effective. The impact of delays and a slower than anticipated ramp up in shaft sinking cycle times, together with experience gained from our first grouting program will be incorporated into  a refreshed schedule and budget which is expected to be completed in the second quarter of 2023. As a final comment, the diamond market remained healthy and stable in 2022, though price softening was observed in the latter half of the year which impacted revenues year over year, achieving the mid-range of guidance. Despite rising global economic uncertainties, our outlook for 2023 and beyond remains optimistic as global supply shortages continue to play out in the market."

DIAMOND MARKET

2022 began on a solid trajectory following a banner year for diamond prices in 2021.  Prices began to soften in the second half of the year in response to increasing global economic and geopolitical uncertainties and resulted in weaker achieved holiday sales results in the US compared to the previous year. Despite this pull back, the market remained stable and price improvement along with increasing market depth has been observed in early 2023.  A cautious economic outlook combined with the uncertainty caused by geopolitical events, including the ongoing conflict in Ukraine and continuing implications of the COVID-19 pandemic (specifically in China where the demand for diamonds has not yet recovered) remain a risk to diamond pricing trends in the short term with demand from the US a critical driver on prices of both rough and polished diamonds. The longer-term market fundamentals remain unchanged and positive, pointing to strong price growth over the next few years as demand is expected to outstrip future supply.

2023 OUTLOOK

This section of the press release provides management's production and cost estimates for 2023.  These are "forward-looking statements" and subject to the cautionary note regarding the risks associated with forward-looking statements. No changes were made to the Company's 2023 Guidance released in December 2022.  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.

DIAMOND SALES

Karowe diamonds are sold through three separate and distinct sales channels: through the HB sales agreement, on the Clara digital sales platform and through quarterly tenders.

HB SALES AGREEMENT FOR +10.8 CARAT DIAMOND PRODUCTION FROM KAROWE

For the three months ended December 31, 2022, the Company recorded revenue of $24.1 million from the HB agreement (inclusive of top-up payments of $3.6 million), as compared to revenue of $31.2 million in Q4 2021 (inclusive of top-up payments of $7.9 million). The decrease in revenue in Q4 2022 versus the comparative quarter can be attributed primarily to the number of high value diamonds delivered to HB earlier in 2021 for which the value of top-ups was, as expected, higher. Top-up values will typically increase as the more valuable stones move through production and become available for sale. A lower number of carats was delivered to HB in Q4 2021 (1,895 carats) compared to Q4 2022 (2,812 carats), however, the initial value of the shipments was comparable owing to the value of stones delivered in Q4 2021. 

At December 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 2022. As these stones finish the manufacturing process, the Company may record additional revenue in the form of "top-up" payments when these diamonds are sold.

Despite the overall decrease in revenue recognized in Q4 2022, diamond market fundamentals continued to support healthy prices as steady demand and some inventory shortages were reported. Natural variability in the quality profile of the +10.8ct production in any production period or fiscal quarter results in fluctuations in recorded revenue and associated top-ups between periods is expected.  During Q4 2022, 8.2% weight percentage of Specials of total carats recovered was consistent with the Karowe resource model.  As more North and Centre lobe material is expected to be processed in 2023, while higher grade, the weight percentage of Specials is expected to decrease.

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.  Trial sales with a third-party producer continued through Q4 2022, with encouraging results and positive margin earned.  Transaction volumes were supplemented with other secondary market supply, which included diamonds purchased by the Company and re-sold through Clara.  Karowe goods transacted through Clara represented approximately 60% of the total sales volume transacted during 2022.  The Company intends to continue to seek additional supply in 2023, both from third-party producers and the secondary market.   

During Q4 2022, the sales volume transacted was $6.6 million (Q4 2021: $7.7 million), as fewer sales were held within the period.

QUARTERLY TENDER

The Q4 2022 tender reflected a good performance in rough diamond pricing across all tendered size classes, although lower than what was achieved in the first two quarterly tenders of 2022 and higher than the price achieved in September as concerns of a global economic slowdown became more prominent against a backdrop of high inflation, interest rate increases and uncertainty in supply chains. A total of 76,264 carats were sold in the December 2022 tender, generating revenues of $12.2 million (Q4 2022 tender: $19.0 million for 97,211 carats).

KAROWE UNDERGROUND EXPANSION UPDATE

The Karowe UGP is expected to extend the mine life to at least 2040, with initial 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 updated estimated capital cost for the Karowe UGP is $547 million (including contingency) and reflects expected pricing changes following execution of the main sink contract in Q2 2022.  Mine ramp up is expected in 2026 with full production from the Karowe UGP expected in H2 2026.  The Company is using a combination of cash flow from operations and project debt for the investment in the Karowe UGP, which is fully financed.

During the three months ended December 31, 2022, a total of $22.3 million was spent on the Karowe UGP development, primarily in relation to ongoing construction activities and procurement of long lead items, including:

• Main sinking in the production and ventilation shafts:
• Cover grouting began in the production and ventilation shafts in December 2022 in response to expected water inflows from the sandstones. Planned methodology, which includes the use of chemical grouting, has been effective. Experiences gained from this first grouting event, which was subsequently completed in February in the production shaft and remains ongoing in the ventilation shaft, will inform future anticipated cover grouting events as the shafts progress to depth.
• Main sinking activities continued to ramp up in Q4, however, equipment and operational challenges continued to negatively impact planned cycle times. Cycle time is the period it takes to complete a series of activities within the sinking process to achieve the next planned vertical advance. Active interventions and mitigations implemented in Q4 including equipment and personnel changes as well as shift and rotation schedule optimization along with the roll-out of a behavioural-based safety training program are helping to resolve these issues.
• The Company intends to assess the impact of the incurred delays against the effectiveness of the operational changes implemented in Q4 2022 combined with recent grouting experiences to refresh estimates around planned sinking rates and overall project schedule and budget, before the end of Q2, 2023.
• The 29 km, 132kV bulk power supply powerline, including the Letlhakane and Karowe substations, was energized and handed over to the Botswana Power Corporation at the end of December 2022.
• The 11kV transmission line to the project site was commissioned in mid-January 2023. This represents a significant milestone for the Karowe UGP as it is now fully powered through grid-supplied electricity. Back-up power will continue to be provided by diesel generators.
• Procurement of shaft station underground mobile equipment progressed with equipment deliveries expected to commence in Q1 2023.
• The underground mine bulk air cooler and shaft cooling tender was awarded.

Activities for the Karowe UGP in Q1 2023 are expected to include the following:

• Sinking and grouting within both the ventilation and production shafts.
• Procurement of underground equipment, including dewatering pumps and underground crush and convey systems.
• Development of a request for proposal for the underground lateral development work.
• Continuation of detailed design and engineering of the underground mine infrastructure and layout.
• Transition of the temporary power supply to a back-up power configuration; and,
• Stage two of the bulk power supply upgrade to connect all mine power requirements to the new Karowe Substation and 132kV power line.
