Lucara unveils diamond recoveries from Botswana mine

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.”

Lucara Diamond revives sales deal with gem trader HB Antwerp

Lucara Diamond has revived a gem sales agreement with polishing and trading company HB Antwerp, it said on Monday, five months after severing ties with the Belgian business.

Canadian miner Lucara said it will supply HB Antwerp with rough diamonds of 10.8 carats and above for 10 years from last December.

Lucara had terminated its relationship with HB Antwerp last September because of what it said was “a material breach of financial commitments”.

HB Antwerp declined to comment on the matter at the time and did not respond immediately to a request for comment on Monday.

Botswana, where Lucara mines diamonds at its Karowe project, has been reassessing plans to acquire 24% of HB Antwerp.

The two companies’ first diamond sales agreement was struck in 2020 and extended for 10 years in 2022.

Lucara said the purchase price for rough stones in its revised deal would be based on mutual agreement of the estimated value of polished diamonds, with a further payment based on actual achieved polished sales.

The pricing mechanism is expected to deliver regular cash flow, Lucara said.

“This partnership reflects our commitment to ensuring stability and sustainability in our operations,” said Lucara chief executive William Lamb.


Gem Diamonds and Lucara find first big stones of 2024

Africa-focused miners Gem Diamonds and Lucara Diamond have recovered big, high-quality Type IIa diamonds at their respective operations.

Gem Diamonds said on Thursday it had unearthed a 295-carat rough stone at its Letšeng mine in Lesotho, adding to a long list of diamonds over 100 carats found at the operation over the past two years.

The prolific mine is one of the world’s ten largest diamond operations by revenue. At 3,100 metres (10,000 feet) above sea level, Letšeng is also one of the world’s most elevated diamond mines.

Canada’s Lucara recovered a 166-carat rough in the Coarse X-Ray Transmission unit at its Karowe diamond mine in Botswana. The company said the precious stone was sourced from direct milling of ore from the South lobe of the mine.

Lucara’s latest find is the 328th diamond over 100 carats found at Karowe since it began operations in 2012. Chief executive William Lamb said  the recovery further supported the economic rationale for investing in the underground expansion project to extend the mine’s life to at least 2040.

The recoveries bring some positive news into a market affected by ongoing weak conditions, with prices for wholesale polished diamonds dropping 20% last year, which also dragged down rough diamond prices. 


Lucara Unearths 692ct. Rough at Karowe

Lucara Diamond Corp. has recovered a 692.3-carat diamond from its Karowe mine in Botswana, the second massive rough from the deposit this month.

The white, type IIa stone came from the EM/PK(S) unit in the south lobe, known for its large, high-quality rough, Lucara said Monday. The miner found the diamond via its XRT unit, which uses X-ray technology to identify huge stones in large pieces of ore before they get broken up.

The new discovery is the fourth diamond over 300 carats that Lucara has unearthed so far this year, including one earlier this month: a high-quality white, type IIa rough weighing 1,080.1 carats, which the miner announced on August 8.

In addition, “this stone is the 20th diamond larger than 100 carats recovered during 2023 at Karowe,” said Lucara CEO William Lamb. “The recovery of large diamonds from the EM/PK(S) lithology of the south lobe strongly supports our expectations for the underground project.”

Lamb, who replaced Eira Thomas as CEO earlier this month, will lead the continued development of Karowe’s underground expansion. The miner invested $683 million in the project, which it believes will extend the mine’s life until at least 2040, 15 years beyond the original 2025 closure date.

In its most recent results, Lucara announced a 21% drop in its second-quarter revenue to $41.1 million amid a slowdown in market demand. Profit slid 60% to $5 million.


Lucara finds blue and pink diamonds at Botswana mine

Canada’s Lucara Diamond continues to find gem quality, coloured diamonds at its Karowe mine, in Botswana, which in April yielded the 1,758 carat Sewelô meaning “rare find” diamond, the largest ever recovered in the African country.

The Vancouver based miner has now recovered a 9.74 carat blue and a 4.13 carat pink diamond from direct milling of the South Lobe, the area that yielded the famous 1,111 carat “Lesedi La Rona” in 2015.

The announcement comes on the heels of last week’s display of a 123 carat gem quality, top white, Type II diamond, found at the same section of the mine.

It also follows the recent sale of a 2.24 carat blue for $347,222 per carat.

Karowe, which began commercial operations in 2012, has this year yielded 22 diamonds larger than 100 carats, eight of them exceeding 200 carats.

Since the start of the year, the miner has sold 19 diamonds each with an individual price in excess of $1 million at its quarterly tender sales. This includes seven diamonds that fetched more than $2 million each, and one diamond that carried a final price tag of over $8 million.

“Lucara is extremely pleased with the recovery of these rare, sizeable, fancy coloured diamonds, which have the potential to contribute meaningful value to our regular production of large, high-value type IIa diamonds,” chief executive, Eira Thomas, said in the statement.

The precious rocks will be put up for sale in December, during the company’s fourth quarter tender.

Lucara, which has focused efforts on the prolific Botswana mine this year, is close to completing a feasibility study into potential underground production and life of mine expansion at Karowe.


Lucara Names 1,758ct. Diamond ‘Rare Find’

Lucara 1758 carat sewelo

Botswana’s largest rough diamond now has a name, following a public contest held by Lucara Diamond Corp.

The company chose to call the 1,758-carat stone Sewelô, which means “rare find” in the local Setswana language. It was the winning entry from more than 22,000 submissions.

“The largest diamond recovered in Botswana’s history was named by the people of Botswana this evening in a celebration of Botswana’s success,” Lucara CEO Eira Thomas said last week.

The miner has completed its analysis of the diamond — which it recovered in April from the Karowe mine’s high-value south lobe — and is considering its sale options, Thomas added.

Lucara announced the new name during a gala event, at which Botswana President Mokgweetsi Masisi was present.
