2022-11-03 00:30:00

 VANCOUVER, November 2, 2022 /CNW/ (LUC - TSX, LUC - BSE, LUC - Nasdaq Stockholm)

Lucara Diamond Corp. ("Lucara" or the "Company") today reports its results for the quarter ended September 30, 2022.

  • Revenue for the three and nine months ended September 30, 2022 totalled $49.9 million and $170.5 million, respectively.
  • For the nine months ended September 30, 2022, a total of 245,764 carats were sold from Karowe at an average price of $528 per carat, generating revenue of $129.9 million before top-up payments of $33.8 million.
  • A strong U.S. Dollar helped to mitigate increases in input costs, resulting in an operating cash cost of $29.33 per tonne of ore processed(1) for the three months ended September 30, 2022.
  • A strong year-to-date operational performance supports the Company's 2022 revenue guidance of $195 million and $225 million.  Operating cost per tonne on an annualized basis is expected to be at the low-end of 2022 Guidance ($29.50 to $33.50).
  • Rough and polished diamond prices continued to exceed prices from 2021, despite growing global economic uncertainties.
  • On Clara, more than 40% of sales came from third-party goods transacted, reflecting a positive trend towards increased diversification of supply and less reliance on Karowe production. Revenue from sales transacted on Clara during the three months ended September 30, 2022 totalled $8.3 million.
  • Production metrics remained in line with 2022 guidance, with 0.9 million tonnes of ore and 0.5 million tonnes of waste mined, and 0.7 million tonnes of ore processed during the three months ended September 30, 2022.
  • The main sink phase for the production shaft commenced at the end of September; sinking of the ventilation shaft continued.
  • A total project investment of $23.9 million into the Karowe UGP during the current quarter focused on the transition to main sink activities for both shafts, procurement of underground mobile equipment and construction of the upgraded transmission line and related substations.

Eira Thomas, President & CEO commented: "Lucara remains on track for another solid year, with sales from our large, high value diamonds continuing to achieve consistent, healthy polished prices under our committed supply agreement with HB, despite recent market softening.  Clara also continued to make good progress during the quarter, adding third party supply from both producer trials and secondary market sources, to positive results. Importantly, third party supply now accounts for more than 40% of sales on Clara.  It was also a busy and productive period for the underground project.  Main sinking commenced on the production shaft and mitigations implemented during the third quarter in response to operational start-up challenges are beginning to take effect, with progress made to reduce cycle times for both production and ventilation shafts."

  • Operational highlights from the Karowe Mine for the three months ended September 30, 2022 included:
  • Mined 0.9 million tonnes (Q3 2021: 1.2) and 0.5 million tonnes (Q3 2021: 0.7) of ore and waste, respectively.
  • Processed 0.7 million tonnes of ore (Q3 2021: 0.7) and recovered 78,879 carats (Q3 2021: 95,907 carats), achieving a recovered grade of 11.4 carats per hundred tonnes (Q32021:13.0cpht).
  • A total of six diamonds greater than 100 carats including one stone greater than 200 carats were recovered during the quarter.
  • The year-to-date Total Recordable Injury Frequency Rate ("TRIFR") of 0.32 (Q3 2021: zero) at the end of Q3 2022 reflects four medical treatment cases reported during the third quarter of 2022.

  • Financial highlights for the three months ended September 30, 2022 included:

  • Revenues from the sale of 99,301 carats recovered from the Karowe Mine were $46.5 million. The sales agreement with HB Trading BV ("HB") accounted for 58% of total Karowe revenue recognized in the quarter.
  • Operating cash costs of $29.33 per tonne processed(1) on plan reflect the impact of higher input costs, partially offset by a comparatively stronger U.S. Dollar.
  • Adjusted EBITDA(1) of $13.8 million and net income for the quarter of $1.8 million ($0.00 basic earnings per share). 

  • Cash position and liquidity:

  • As at September 30, 2022, the Company had cash and cash equivalents of $34.8 million.
  • Drawn $65.0 million from the $170.0 million project loan facility.
  • The working capital facility of $50.0 million was undrawn as at September 30, 2022.

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. No changes were made to the Company's 2022 Guidance as of Q3 2022.  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.

(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 were 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.


Diamond sales in Q3 2022 continued 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. Other diamonds continued to be sold through a combination of the Clara platform and regular tenders.

The Company recognized total revenues of $49.9 million in Q3 2022. This included $46.5 million from the sale of 99,301 carats from Karowe, top-up payments of $9.0 million as well as $3.4 million from the sale of third-party goods on the Clara platform. In the comparative quarter, the Company achieved revenues of $72.7 million which included $72.5 million from the sale of 117,162 carats from Karowe, top-up payments of $2.7 million as well as $0.2 million in revenue from third-party goods sold through the Clara platform.


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 agreement 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.

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 value 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 September 30, 2022, the Company recorded revenue of $27.1 million from the HB agreement (inclusive of top-up payments of $9.0 million), as compared to revenue of $50.5 million in Q3 2021 (inclusive of top-up payments of $2.7 million). The decrease in revenue in Q3 2022 versus the comparative quarter can be attributed primarily to the number of high value diamonds delivered to HB in Q3 2021 (four pink diamonds and two Type IIa top white gem diamonds (393.5 carats and 257.5 carats)) for which an initial MPV payment was received in Q3 2021.  In addition, more carats were delivered to HB in the comparative quarter (6,258 carats vs.2,412 carats).  Despite the overall decrease in revenue recognized in Q3 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 Q3 2022, 7.1% weight percentage Specials of total carats recovered was consistent with the Karowe resource model.

As a result of the sales agreement with HB, the Company also participated in polished diamond price increases during Q3 2022 as rough diamonds sold to HB in previous quarters were polished and sold.  In Q3 2022, estimated top-up payments of $9.0 million (Q3 2021: $2.7 million) were included in revenue for the quarter. At September 30, 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 the first nine months of 2022.  As these stones finish the manufacturing process and are sold, the Company' may record additional revenue in the form of "top-up" payments from these sales.


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 Q3 2022, four sales (Q3 2021: four sales) took place with a total sales volume transacted of $8.3 million, a 26% increase from the $6.6 million transacted in Q3 2021, as Karowe goods were supplemented by growth in supply from additional sources. The number of buyers on the platform remained stable during the quarter with the Company maintaining a waiting list to manage supply and demand. 

Additional supply is required to meet existing demand and drive the platform's growth and the Company continued trial sales on the Clara platform with a third-party producer in Q3 2022.  The Company intends to continue to seek additional supply in 2022, both from third-party producers and the secondary market. 


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 September 30, 2022, a total of $23.9 million was spent on the Karowe UGP development, primarily in relation to ongoing construction activities and procurement of long lead items, including:
  • Main sinking of the production shaft commenced at the end of September while main sinking in the ventilation shaft continued.  As main sinking activity ramped up in the ventilation shaft during the third quarter, several operational issues arose resulting in sinking rates achieving less than plan due to longer cycle times. In response to the operational challenges and longer duration cycle times, changes and mitigations were actioned during the quarter. Observed cycle times and sinking rates are improving. The start of main sink activity in the production shaft was delayed due to longer than planned commissioning of the winders and hoisting plant.  Cycle times are now improving.
  • Procurement of shaft station underground mobile equipment progressed with equipment deliveries expected to commence in Q4 2022 and Q1 2023.
  • The Letlhakane and Karowe substation construction continued with focus on civil work and cable pulling for control equipment installation. The transmission line towers were equipped with stringing hardware and safety nets were installed over existing line crossings.
Activities for the Karowe UGP in the fourth quarter of 2022 are expected to include the following:
  • Sinking within both the ventilation and production shafts.
  • Procurement of underground equipment, including awarding the bulk air cooler tender.
  • Continuation of detailed design and engineering of the underground mine infrastructure and layout.
  • Commissioning the 29 km, 132kV bulk power supply powerline.


After a strong start to the third quarter of 2022, diamond price softening was observed in late August and into September, however, solid market fundamentals continue to support diamond prices despite growing concerns of a global economic slowdown. High levels of reported inflation persisted, and governments responded with increasingly forceful measures in attempts to reduce it to sustainable levels.

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, however, pointing to strong price growth over the next few years as demand is expected to outstrip future supply.

The benefits of the committed sales agreement with HB continued to be realized during the third quarter of 2022 as the Company participated in the upside to manufacturing polished diamonds for goods 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.
