LUCARA RECOVERS EPIC 2,492 CARAT DIAMOND FROM THE KAROWE MINE
Lucara Diamond Corp. (“Lucara” or the “Company”) is thrilled to announce the recovery of an exceptional 2,492 carat diamond from its Karowe Diamond Mine in Botswana. This remarkable find, one of the largest rough diamonds ever unearthed, was detected and recovered by the Company’s Mega Diamond Recovery (“MDR”) X-ray Transmission (“XRT”) technology, installed in 2017 to identify and preserve large, high-value diamonds. The stone was recovered from the processing of EM/PK(S) kimberlite, the dominant ore type that Lucara will continue to target during the first years of the Company’s underground mining operations.
This discovery underscores Karowe’s reputation as a world-class asset and reaffirms Lucara’s position as a leading producer of large, exceptional diamonds. This latest recovery joins an impressive roster of other significant finds from the mine, including the 1,758 carat Sewelô and the 1,109 carat Lesedi La Rona.
William Lamb, President and CEO of Lucara, commented on this historic discovery: “We are ecstatic about the recovery of this extraordinary 2,492 carat diamond. This find not only showcases the remarkable potential of our Karowe Mine, but also upholds our strategic investment in cutting-edge XRT technology. The ability to recover such a massive, high-quality stone intact demonstrates the effectiveness of our approach to diamond recovery and our commitment to maximizing value for our shareholders and stakeholders.”
Mr. Lamb added, “This discovery reinforces Karowe’s position as a truly world-class diamond mine and highlights the continued success of our operational and underground development strategy.”
Botswana’s diamond industry delivers wide-ranging socio-economic benefits to the country that extend well beyond the mining sector. Its influence supports national development by funding critical areas such as education and healthcare.
This discovery symbolizes Botswana’s continued ascent as a global leader in diamond production. It represents not only the unparalleled wealth found in Botswana’s soil, but also the remarkable progress the nation has made in developing its diamond industry for the benefit of its citizens.

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 Diamond Corp. has announced the recovery of a 320-carat, 111-carat, and two +50-carat stones from its 100% owned Karowe Diamond Mine located in Botswana.
These diamonds were recovered from the direct milling of EM/PK(S) kimberlite ore from the South Lobe during a recent production run that saw additional recoveries of numerous, smaller +10.8 carat diamonds of high value.
The 320-carat is a gem-quality, top light brown diamond, while the 111-carat diamond is described as a Type IIa white stone of high quality. The two +50-carat stones add to these recent recoveries and are also Type IIa white diamonds. These recoveries add to the collection of significant diamonds recovered at Karowe and further solidifies Lucara’s reputation as a leader in the recovery of large, high-quality diamonds.
The recoveries from the EM/PK(S) unit highlight the continued success of Lucara’s mining operations at the Karowe Diamond Mine and reinforce the development of the underground mine which will target >95% EM/PK(S) ore during the first three years of underground production. The company’s adoption of advanced diamond recovery technology has enabled the continued identification and retrieval of these extraordinary diamonds and strong resource performance.
William Lamb, President and CEO of Lucara Diamond Corp., commented on the recent discoveries, stating:
“These diamond recoveries from the EM/PK(S) domain of the South Lobe further validate the quality and potential of the Karowe Diamond Mine. We are thrilled with the consistent success we continue to achieve in uncovering large, high-value diamonds, reaffirming Lucara’s position as a leading producer of large high-quality gem diamonds. Our team’s dedication to innovation and operational excellence continues to drive our success, and we look forward to delivering further value to our stakeholders through these extraordinary discoveries.”
Canadian miner Lucara Diamond has announced that it expects to sell between $200 million to $230 million worth of diamonds from its Karowe mine in Botswana in 2023 – an increase over its previous forecast of $185-$215 million in 2022, IDEX Online reports.
Lucara also said it expects to sell 385,000 to 415,000 carats (up from 300,000 to 340,000 carats in 2022) and expects to recover 395,000 to 425,000 carats (an increase from 300,000 to 340,000 carats).
Recently, Lucara announced that it has extended its sales agreement with HB Trading to sell +10.8-carat rough diamonds from Karowe for another ten years. Lucara and HB partnered in 2020 to sell Karowe’s large, high-value diamonds “that have historically accounted for about 60% to 70% of its annual revenues,” according to a report by Rough & Polished.
62.7-carat fancy pink diamond “Boitumelo” in Botswana
Lucara keeps raking in the big diamond finds, this time recovering a 62.7-carat fancy pink diamond from its Karowe mine in Botswana.
It is the largest fancy pink gem to found in Botswana, according to the diamond miner, and one of the largest rough pink diamonds on record in the world.
The stone has been named “Boitumelo,” which means joys in Setswana.
Measuring 26 x 17 x 16 mm, it is described as a high-quality fancy pink Type IIa gem.
Lucara uncovered it from the direct ore milling at the EM/PK(S) unit of the South Lobe, the site of many of its biggest finds.
The company said a 22.21-carat fancy pink gem of similar quality was found during the same production period, as were two more pink gems of similar color weighing 11.17 carats and 5.05 carats.
Asked if those additional small pink diamonds could’ve broken off from the same piece as the 62.7-carat diamond, a company spokesperson said: “As the diamonds all came from a similar production period it may be possible, but we cannot confirm this at this time. Further detailed analysis needs to be carried out to confirm if they did indeed originally stem from one diamond.”
Regarding the find, CEO Eira Thomas said, “Lucara is delighted to announce another historic diamond with the recovery of the Boitumelo, and very pleased to demonstrate the continued potential for large, colored diamonds from the South Lobe production.
“These remarkable pink diamonds join a collection of significant diamond recoveries in 2021 produced from the EM/PK(S), which forms a key economic driver for the proposed underground mine at Karowe.”
Lucara Diamond Corp. is pleased to announce the recovery of a 1,174.76 carat diamond from its 100% owned Karowe Diamond Mine located in Botswana.
The diamond, measuring 77x55x33mm, is described as a clivage gem of variable quality with significant domains of high-quality white gem material, and was recovered from direct milling of ore sourced from the EM/PK(S) unit of the South Lobe.
The 1,174 carat diamond represents the third +1,000 carat diamond recovered from the South Lobe of the AK6 kimberlite since 2015 including the 1,758 carat Sewelô and 1,109 carat Lesedi La Rona.
The 1,174.76 carat diamond was recovered in the Mega Diamond Recovery XRT circuit. On the same production day, several other diamonds of similar appearance (471 carat, 218 carat, 159 carat) were recovered at the main XRT circuit, indicating the 1,174 diamond was part of a larger diamond with an estimated weight of > 2000 carats.
The MDR is positioned after the primary crusher, ahead of the autogenous mill, and is the first opportunity for diamond recovery within the circuit.
470 carat diamond recovered from the Karowe Mine in Botswana
Lucara Diamond Corp. is pleased to announce the recovery of a 470 carat top light brown clivage diamond from its 100% owned Karowe Diamond Mine located in Botswana.
The diamond, measuring 49x42x26mm, was recovered from direct milling of ore sourced from the EM/PK(S) unit of the South Lobe. The 470 carat recovery forms a notable contribution to a series of top quality gem and clivage quality diamond recoveries during a recent production run, including an additional 5 diamonds greater than 100 carats (265ct, 183ct, 161ct, 116ct, 106ct) and 13 diamonds between 50 and 100 carats in weight.
The May production run, dominated by EM/PK(S) ore, produced diamonds greater than 10.8 carat in weight accounting for 12.7% weight percent of total production, exceeding resource expectations. Continued strong resource performance and recovery of large diamonds reinforces the significance of the EM/PK(S) as an important economic driver for the proposed underground mine at Karowe.
The 470 carat diamond was recovered in the Coarse XRT circuit and represents the third +300 carat diamond recovered to date in 2021. Year to date, Karowe has produced 10 diamonds greater than 100 carats including 6 diamonds greater than 200 carats, including the 341 carat (link to press release) and 378 carat (link to press release) top white diamonds recovered in January 2021.
The Karowe mine has produced a 998-carat diamond, the latest in a string of large rough stones from the lucrative deposit in Botswana.
Lucara Diamond Corp., which owns Karowe, will work with manufacturing partner HB Antwerp to assess how to maximize value from the rough, the miner said Wednesday. The unbroken, high-white, clivage stone — meaning it needs to be split before further processing — came from the EM/PK(S) unit of the site’s south lobe, which has yielded some of the world’s biggest and most famous diamonds.
“Lucara is extremely pleased with the continued recovery of large, high-quality diamonds from the south lobe of the Karowe mine,” said CEO Eira Thomas. “To recover two [500-carat-plus] diamonds in 10 months, along with the many other high-quality diamonds across all the size ranges, is a testament to the unique aspect of the resource at Karowe and the mine’s ability to recover these large and rare diamonds.”
The EM/PK(S) area produced the 1,109-carat Lesedi La Rona in 2015, as well as the 1,758-carat Sewelô, which HB bought in January this year in collaboration with luxury brand Louis Vuitton.
The Belgian manufacturer later agreed to purchase all of Lucara’s rough above 10.8 carats for the remainder of the year. Last week, Lucara announced the sale of a 549-carat diamond from the same high-value patch of Karowe, with HB and Louis Vuitton again partnering on the stone.
The arrangement with HB prevented a heavier decline in Lucara’s sales in the third quarter, the first period in which income from the partnership started appearing in the miner’s top line.
Group revenue fell 9% year on year to $41.3 million in the three months ending September 30, reflecting Lucara’s decision not to hold its usual tenders of stones above 10.8 carats, the company reported Wednesday. Instead, it sold 5,633 carats through the HB partnership, with sales taking place approximately twice a month, while the miner’s online selling platform, Clara, boosted sales of smaller goods.
Total sales volume fell 3% to 112,943 carats, with the average price down 6% to $365 per carat. The company’s net loss deepened by 35% to $5.4 million.
“Lucara is now receiving regular, predictable revenue for its [10.8-carat-plus] diamonds using a superior pricing mechanism based on estimated polished outcomes less a commission and the cost of polishing,” Thomas added.
Lucara Diamond Corp. has sold a 549 carat diamond to Louis Vuitton through a partnership that will see the luxury retailer craft bespoke pieces to match client requests.
“In line with their long tradition of personalization, Louis Vuitton envisages. the ultimate personalized high jewelry experience, and the opportunity to create a truly unique gem, a storied family heirloom,” Lucara said Wednesday. “In this way, the client will be involved in the creative process of plotting, cutting, polishing and becoming part of the story that the stone will carry with it into history.”
HB Antwerp will manufacture the stone, which is the fourth largest in the history of Botswana. Lucara will receive a purchase price based on the estimated polished outcome, which HB will determine using scanning and planning technologies. Louis Vuitton will pay the miner more at a later stage if the final polished price exceeds this estimate, while subtracting manufacturing costs, Lucara noted.
Lucara recovered the 549 carat, unbroken diamond, which is of “exceptional purity,” from the high value EM/PK(S) unit of the south lobe of its Karowe mine in February. It has named the stone Sethunya, which means flower in Setswana.
The miner sold the 1,758 carat Sewelô rough, Botswana’s largest diamond, into the partnership with Louis Vuitton and HB in January.
“We are extremely pleased to be building on the groundbreaking partnership established for the manufacturing of the Sewelô earlier this year,” said Lucara CEO Eira Thomas. “[Louis Vuitton and HB Antwerp will] transform Sethunya. into an extraordinary, bespoke, polished diamond collection, catering exclusively to the desires of Louis Vuitton’s global customer base.”
According to the official, synthetics will “compromise” the value of Botswana’s natural diamonds

Masire said that “Botswana will send a confusing message to its customers should it decide to produce and sale synthetic diamonds”. He added that the Debswana Diamond Company (the joint venture between the government of Botswana and diamond miner De Beers) is searching for other markets other than the US to sell its diamonds, including in China.

Masire “refused to provide an update on the ongoing negotiations between Gaborone and De Beers as disclosure of any information pertaining to the negotiations will potentially influence the outcome”. Botswana and De Beers’ huge 10-year diamond sale agreement is expected to expire by the end of 2020. Botswana accounts for more than two-thirds of De Beers’ diamond production.
