Lucara sells two exceptional diamonds for $54m

1 080 ct Eva Star diamond

Diamond miner Lucara Diamond Corp has sold the 549 ct Sethunya and the 1 080 ct Eva Star diamonds, recovered at its Karowe mine, in Botswana, for $54-million.

The Sethunya, recovered in 2021, and the Eva Star, discovered in 2023, showcase the remarkable quality and size of diamonds consistently produced from the South Lobe of the Karowe kimberlite. These exceptional stones underscore Karowe’s position as one of the world’s most prolific sources of large, high-value diamonds, Lucara states.

“The sale of these two extraordinary diamonds further validates our investment in the Karowe underground project. The unique characteristics of Karowe’s kimberlite, particularly in the South Lobe, continue to amaze us with its ability to produce diamonds of exceptional size and quality. The mineralogy we’re seeing is truly unprecedented in the industry, consistently delivering Type IIa diamonds of remarkable clarity and size,” adds president and CEO William Lamb.

The 549 ct Sethunya diamond

The Karowe mine has yielded some of the world’s largest diamonds, including the 1 758 ct SewelĂ´, recovered in 2019; a 1 174 ct diamond recovered in 2021; and the 1 109 ct Lesedi La Rona, recovered in 2015.

The 1 080 ct Eva Star diamond was the fourth diamond weighing more than 1 000 ct to be recovered at the mine.

This was followed by the recovery of the 2 492 ct Motswedi diamond in August last year and the 1 094 ct Seriti diamond in September last year.

The 2 492 ct Motswedi is the second-largest diamond ever to be recovered, with the largest being the 3 106 ct Cullinan diamond recovered in South Africa in 1905.

The Karowe underground expansion project will extend the mine’s life beyond 2040 and has been designed to access the parts of the South lobe at depth where the EMPKS ore type is prevalent.

Production at the underground mine is scheduled to start in the first half of 2028.

Lucara sold 76 387 ct during the second quarter

Diamond producer Lucara Diamond Corp

Diamond producer Lucara Diamond Corp sold 76 387 ct of diamonds, generating $41.3-million in revenue, during the second quarter ended June 30.

The company recovered 92 419 ct of diamonds at a grade of 12.9 ct for every 100 t of direct milled ore.

Additionally, 8 349 ct were recovered from processing historic recovery tailings. The company recovered 206 special diamonds, defined as rough diamonds weighing more than 10.8 ct, representing 6.9% by weight of the total recovered carats from the second quarter’s processed ore. This aligns with the company’s expectations, Lucara said.

Noteworthy recoveries during the period included a 491 ct Type IIa diamond, a 225.6 ct Type IIa diamond and a 109 ct Type IIa diamond.

Significant progress was made in shaft sinking for the ventilation and production shafts during the second quarter, with the critical path ventilation shaft ahead of the July 2023 rebase schedule. By the end of the quarter, the production and ventilation shafts had reached depths of 557 m below collar and 550 m below collar, respectively.

Operational highlights from the Karowe mine for the quarter included ore and waste mined of 700 000 t, with ore processed totalling 700 000 t.

Financial highlights for the second quarter revealed operating margins of 67%, compared with 59% in the second quarter of 2023. This strong operating margin is attributed to robust pricing for the company’s larger stones and cost reduction initiatives, supported by a strong dollar.

The operating cost was $26.32/t processed, a 6% decrease from $27.97/t in the second quarter of 2023 and consistent with the $26/t in the first quarter of this year.

Lucara believes the impact of inflationary pressures, particularly in labour, was well-managed by the operation, with a strong dollar offsetting a slight increase in costs compared with the previous period.

Adjusted earnings before interest, taxes, depreciation and amortisation (Ebitda) were $18.8-million, up from $16.5-million in the second quarter of 2023, driven by increased revenue and lower operating expenses.

During the second quarter, the company invested $11.2-million into the Karowe Underground Project (KUP), excluding capitalised cash borrowing costs. The ventilation shaft sank 128 m, and development of the 470-level station, located at about 550 m below collar, began.

Production shaft activities included the sinking of 104 m and the completion of three probe hole covers, with no water being intersected. A total of 26 m of lateral development on the 470-level, along with the 470-level station development, was completed.

As of June 30, Lucara reported cash and cash equivalents of $21.9-million and working capital of $21.7-million. The company had drawn $165-million on the $190-million project facility for the KUP, with an additional $25-million drawn on the $30-million working capital facility and a cost overrun reserve account balance of $37.5-million.

The Karowe mine registered no lost-time injuries during the second quarter, taking the mine to more than three years without a lost-time injury.

“Lucara’s performance this quarter reaffirms our position as a leader in the diamond industry. Our . . . safety and operational excellence [record] continues to drive our success, with both our openpit operations and underground construction progressing admirably. The Underground Expansion Project, in particular, is advancing well, with shaft sinking progress surpassing our expectations,” Lucara president and CEO William Lamb said on August 12.

Lucara noted that, in the diamond market, the long-term outlook for natural diamond prices remains positive owing to improving supply and demand dynamics, largely driven by long-term reductions from major producing mines.

However, the market for smaller-sized diamonds remains soft, impacted by a weak Asian market and the rise of laboratory-grown diamonds.

Lucara said demand for larger diamonds over 10.8 ct remained robust, as reflected in the company’s sales.

However, the G7 sanctions on Russian diamonds over 1 ct, effective March this year, have caused some trade delays owing to new regulations requiring these diamonds to be processed through the Antwerp World Diamond Centre for origin verification.

Lucara, with its established operations producing Botswana diamonds, stands to benefit from this heightened focus on origin verification.

Sales of laboratory-grown diamonds increased steadily through 2023 and into this year, with many smaller retail outlets increasingly adopting these diamonds as a product.

In the second quarter, diamond producer De Beers announced that it would cease creating synthetic diamonds and focus on selling natural diamonds. This decision aligns with several major brands confirming they would not market laboratory-grown diamonds.

Lucara said the long-term impact was expected to support the natural diamond market, with a bifurcation between the natural and laboratory-grown diamond markets expected in the medium term.

The company believes that the longer-term market fundamentals for natural diamonds remain positive, as demand is expected to outstrip future supply, which has been declining globally over the past few years.

Lucara Sales Fall Amid Lack of High-Value Diamonds

          Lucara Diamonds – Karowe Diamond Mine

Lucara Diamond Corp.’s sales dropped in the third quarter as the company supplied fewer large and expensive stones from its lucrative Karowe mine in Botswana.

Revenue fell 31% year on year to $49.9 million, while net profit slumped 86% to $1.8 million, Lucara reported Wednesday.

Sales of rough from Karowe declined 36% to $46.5 million, with volume down 15% at 99,301 carats and the average price falling 43% to $337 per carat. The remaining revenue came from sales of third-party goods on Lucara’s Clara online platform.

Management blamed a decrease in the number of high-value diamonds the company sold to HB Antwerp through the pair’s supply agreement. The Belgian manufacturer is contracted to buy all Karowe rough of 10.8 carats or more, with Lucara receiving a proportion of the final polished proceeds.

In the third quarter a year earlier, Lucara sold four pink diamonds and two white, type IIa stones — weighing 393.5 and 257.5 carats — to HB. As a result of the unfavorable comparison, revenue from the agreement plummeted 46% to $27.1 million.

“Despite the overall decrease in revenue recognized in [the third quarter], diamond-market fundamentals continued to support healthy prices as steady demand and some inventory shortages were reported,” Lucara said. Fluctuation in the availability of 10.8-carat production is expected, it added.

Output from Karowe slid 19% year on year to 78,879 carats for the quarter.
