Lucara’s 62-Carat Fancy Pink ‘Boitumelo’

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.”

World’s third largest diamond discovered in Botswana

1,098 carat rough diamond

The diamond firm Debswana has announced the discovery in Botswana of a 1,098-carat stone that it described as the third largest of its kind in the world.

The company’s acting managing director, Lynette Armstrong, presented the stone, which was found on 1 June, to the country’s president, Mokgweetsi Masisi, on Wednesday.

It is the third largest in the world, behind the 3,106-carat Cullinan found in South Africa in 1905 and the 1,109-carat Lesedi La Rona discovered in Botswana in 2015.

“This is the largest diamond to be recovered by Debswana in its history of over 50 years in operation,” Armstrong said.

“From our preliminary analysis it could be the world’s third largest gem-quality stone. We are yet to make a decision on whether to sell it through the De Beers channel or through the state owned Okavango Diamond Company.”

The “rare and extraordinary stone … means so much in the context of diamonds and Botswana,” she said. “It brings hope to a nation that is struggling.”

The minerals minister, Lefoko Moagi, said the discovery of the stone, which is yet to be named but measures 73 by 52 by 27mm, could not have come at a better time after the Covid-19 pandemic hit diamond sales in 2020.

Debswana is a joint venture between Anglo American’s De Beers and the Botswanan government, which receives as much as 80% of the income from sales through dividends, royalties and taxes.

Production at Debswana fell by 29% in 2020 to 16.6m carats and sales fell by 30% to $2.1bn as the pandemic affected production and demand.

Debswana plans to increase output by as much as 38% to pre-pandemic levels of 23m carats in 2021 as the global diamond market recovers with the easing of travel restrictions and reopening of jewellers.

Lucara Recovers 470 Carat Diamond from the Karowe Mine in Botswana

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.

Lucara Secures $220M in Financing to Take Mine Underground

Karowe Mine in Botswana
Karowe Mine in Botswana 

Lucara Diamond Corp. said it has secured $220 million in financing to help take the Karowe Mine in Botswana underground and extend its life by about 20 years.

Karowe is responsible for producing some of the most significant diamonds recovered in recent years, including the 1,109-carat “Lesedi La Rona,” which Graff bought for $53 million, and a 1,758-carat diamond that Louis Vuitton is turning into jewelry.

The credit-approved senior debt facilities include two tranches: $170 million to go toward the development of the underground mine and $50 million to support the ongoing operation of the open pit.

The underground expansion has an estimated capital cost of $514 million and is expected to take five years. The balance of development capital for the project is expected to come from cash flow from the mine’s ongoing open-pit operations.

In a statement announcing the financing, Lucara President and CEO Eira Thomas called securing the financing “an important achievement for Lucara and a strong endorsement of our underground expansion plans.”
She said the loans will supplement the cash flow from the open-pit portion of Karowe for the next five years and will extend the life of the mine from 2025 to at least 2040.

The five lenders on the $220 million financing facility for Lucara are: ING Bank N.V., Natixis, the London branch of Societe Generale, Africa Finance Corp., and Afreximbank. Thomas described them as having “significant mining and metals track records and experience in Africa.”

Closing on the facilities is subject to completion of definitive documentation and the satisfaction of certain terms and conditions, including Know Your Customer (KYC) checks.

The target closing date for the financing package is mid-2021, with financing expected to be in place by the second half of the year.

Lucara made the financing announcement the day before it released its first-quarter 2021 results.

Revenues totaled $53.1 million, or $579 per carat sold, for the miner in Q1. Net income was $3.4 million.

That is a significant improvement over Q1 2020, when the onset of the pandemic limited sales to $34.1 million and caused Lucara to record a loss of $3.2 million.

First-quarter 2021 results also are up when compared with 2019, when Lucara reported revenues of $48.7 million, or $512 per carat sold. Net income for the latter, however, was higher at $7.4 million.

The company said overall, the diamond market started 2021 in its healthiest position in five years following strong holiday seasons in the United States and China, and careful rough supply management by producers, which has helped to recalibrate polished inventories.

Botswana Diamonds shares good news from Thorny River

Thorny river diamonds

Botswana Diamonds has announced that eleven diamonds and abundant kimberlitic indicators were recovered from drill samples at the recently discovered River Kimberlite pipe at Thorny River in South Africa.

John Teeling, Chairman, commented:

“The recovery of so many kimberlitic indicators and in particular diamonds, which are very rare to recover in small sample narrow reverse circulation drill holes is highly encouraging and bodes well for the potential commerciality of this exciting discovery”.

Following a detailed ground geophysical programme in October 2020, 6, six-inch percussion reverse circulation holes were drilled into the newly discovered River Kimberlite pipe.

A combined total of 39.5 m intersected kimberlite while an additional 55 m intersected a weathered kimberlite breccia.

Samples from these holes were taken at one metre intervals and twenty of these totalling about 500 kg were selected and submitted to an independent processing facility for assessment through screening, dense media separation and hand sorting.

11 Diamonds, 172 G10 pyrope garnets, 623 G9 pyrope garnets, 555 eclogitic garnets, 438 chromites and 268 chromium diopsides (clinopyroxene) were recovered at sizes between -1.0+0.3mm.

Recoveries of a specific mineral species were capped at 20 grains and thus this picture is a snapshot of the overall sample indicator content. Importantly, all the samples contained abundant kimberlitic indicators.

The diamonds are all notably of good colour and clarity and are of commercial quality and in high demand by the market. The diamonds were not weighed as the sample size was small and they are not representative of a possible population.

Pyrope garnets are common in peridotite xenoliths from kimberlite pipes, some of which are diamond-bearing. Pyrope found in association with diamond commonly has a Chromium Oxide content of three to eight percent which imparts a distinctive violet to deep purple colouration.

These are called G10 and G9 pyrope garnets. Eclogites typically result from high to ultrahigh pressure metamorphism of mafic rocks at low thermal gradients as they were subducted to the upper mantle in a subduction zone.

Garnets found in eclogitic xenoliths tend to have a deep orange colour. Diamonds in kimberlite come from both peridotitic and eclogitic xenoliths so the abundance of both types of garnet in this sample is noteworthy and this is supported by the recovery of diamonds from a relatively small drill sample.

Of significance too is that these diamonds are all of good colour and clarity. The next step is a detailed core drilling programme which is planned for the dry season.

Lucara recovers 998Carat Rough Diamond

998 carat rough diamond

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.

Botswana Diamonds identifies five targets likely to be kimberlites

Botswana Diamonds Thorny River

The targets identified are very similar to the pipe that constituted the high-grade and famous De Beers Marsfontein mine, in so much as the pipe had little surface indication due to dolerite rock cover but grew and swelled below the dolerite.

Much of the Thorny River area geology is comprised of a dolerite dyke swarm.

John Teeling, chairman, comments:

“It has long been held that there should be high grade kimberlite pipes other than the Marsfontein mine in the Thorny River area.

“The geology made discovery difficult. New geophysical technology tries to see through the dense dolerite cover.

“The company pioneering the work, Subterrane, believe they have identified five targets likely to be kimberlites.

“We are working to better define where to drill. The targets are shallow so will not be expensive to drill”.

Conventional geophysical techniques have been unable to detect kimberlites under the dolerite including those that are deeper seated. Subterrane, a partner using its proprietary technology, enables the company to explore geophysical anomalies beneath the dolerite and those that are buried.

This could lead to the discovery of kimberlites similar to Marsfontein.

Thus far Subterrane has identified five such target areas within the Thorny River project.

De Beers, Botswana Prep for New Sales Deal

De Beers Botswana

Botswana once again finds itself at a crossroads. The sparsely populated, landlocked country is in a constant battle to ensure the longevity of its diamond industry.

Recognizing that diamond mining will not last forever, the government’s beneficiation program has sought to establish cutting and polishing, trading, and auxiliary services in an effort to diversify its industry — and economy — away from its reliance on the mining sector.

Beyond mining

De Beers, which counts around 59% of its production by value in Botswana, has played no small part in that effort. It did so initially by earmarking a part of its rough supply to be manufactured in Botswana, and today there are 18 sightholders with factories in the country. In 2013, De Beers moved its sales headquarters to Gaborone, meaning that its 10 annual sights were taken out of London, thus diverting traffic and diamond-related activity to the African city.

Furthermore, the establishment of the parastatal Okavango Diamond Company that same year gave the government access to 15% of production by Debswana, its joint mining venture with De Beers. That was the first time substantial rough sales from Debswana took place outside of the De Beers system.

The 2011 agreement that governed those developments is up for renewal in 2020, and negotiations are expected to begin in the coming year. For its part, the government is seeking to increase supply to local sightholders as a means of creating more jobs, newly elected President Mokgweetsi Masisi told Bloomberg in May.

Some question whether Botswana can handle more manufacturing, given that a few factories have closed in recent years. If profitability remains the biggest challenge facing manufacturers, Gaborone has yet to prove itself as a viable center for high-volume cutting. Perhaps De Beers can play a further role there, too.

The government will also likely want to increase the percentage of Debswana supply that Okavango receives. And it might want to renegotiate greater access to the large and high-value diamonds Debswana recovers.

Digging deep

Botswana has some leverage in the relationship with De Beers. It owns a 15% stake in the group, with Anglo American holding the remaining 85%. And the two are equal partners in Debswana and in DTC Botswana, which sorts and mixes production for De Beers and Okavango.

De Beers, meanwhile, brings to the table its mining expertise and budget. In 2010, it committed to investing $3 billion over 15 years in the Cut-8 expansion of the Jwaneng mine — considered the world’s most valuable diamond-producing asset.

That project is already the main source of ore at Jwaneng and is expected to  extend the life of mine to 2030 and by some 93 million carats. Studies for the viability of Cut-9 are under way, which would further extend the life of Jwaneng. A final investment decision on the project is expected later this year, reports a De Beers spokesperson.

De Beers could use the potential Cut-9 investment, as well as funding extensions at the Orapa and Letlhakane mines, as a bargaining tool in negotiations with the government.

African investments

De Beers walks a similarly fine line in other African countries where it operates.

In South Africa, it may have to reduce ownership of its local businesses from 74% to 70% under the new mining charter, as the government wants to see more local black economic empowerment (BEE) involvement. That said, De Beers is engaged in a $2 billion project to develop underground mining at the Venetia asset. From next year, Venetia will be its only mine in South Africa, as it plans to close the Voorspoed mine. It has already sold the Finsch, Cullinan and Kimberley operations over the past decade.

Meanwhile, in May 2016, De Beers signed a 10-year sales agreement with Namibia, in which it ceded 15% of local supply to the government and promised more diamonds to local cutters. The company subsequently announced major investments in its marine mining operations off the Namibian coast.

It’s that give-and-take that Masisi is hoping will result in a “win-win” for both parties as they negotiate their next long-term deal — especially given that so much of Botswana’s future diamond production depends on Jwaneng’s expansion.

“We have had a wonderful relationship with De Beers, and we expect that relationship to be even more cemented,” the president told Bloomberg in May. “The returns [from the Jwaneng development] are going to be realized in the period of the next deal. This is a marriage we’re after.”
