World’s third largest diamond discovered in Botswana

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 Secures $220M in Financing to Take Mine Underground

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

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

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 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.

Botswana Diamonds identifies five targets likely to be kimberlites

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.

Botswana Diamonds Shares Jump On Licence Extension

Shares in Botswana Diamonds PLC jumped Thursday after it extended two “strategic” diamond licences for further two years, as it considered forming a joint venture to develop the projects.

Shares in Botswana Diamonds were 9.9% higher at 0.54 pence in London on Thursday.

Botswana Diamonds – through its wholly-owned Sunland Minerals Ltd subsidiary – extended the Prospecting Licences PL232 and PL235 in Botswana to the end of September 2021.

The firm explained the “key” licences were “strategically located” in the centre of the Kalahari Desert in Botswana, covering 500 square kilometres. Botswana Diamonds has already identified “prospective drill ready targets” following “intensive” work at the sites.

Botswana Diamonds said it was “already in extended discussions” with a “major” diamond producer regarding the formation of a joint venture for the next phase of the work on the licences.

De Beers Cuts Prices as Rough Sales Slide

De Beers’ rough-diamond sales slumped to a 20-month low of $390 million in June amid weak sentiment in the manufacturing sector. Sightholders noted the price cuts De Beers implemented on certain categories were not enough to stimulate demand.

“The reaction to the price adjustments was lukewarm,” observed one Antwerp-based manufacturer who attended last week’s sale in Gaborone. “It’s a case of too little, too late, as polished prices have declined and we’re not seeing the same movement in the rough market.”

De Beers reduced prices by an estimated 4% to 8% on low-quality and smaller stones, sight participants reported. Sightholders who spoke with Rapaport News expected the company would need to make further cuts later this year, but recognized it was unlikely to do so at the next sight.

“We don’t expect a correction in July because that will start a downward spiral,” said one India-based sightholder. “But people will refuse goods. The mood is not good, even after this month’s reduction, as manufacturers are under pressure.”

High inventory

De Beers CEO Bruce Cleaver noted that rough buyers were cautious in June due to higher-than-normal polished-diamond inventories in the midstream. The sight was the lowest on record by De Beers since October 2017, and sales were down 33% compared to last June.

Manufacturers have cut production by an estimated 20% to 30% this year to reduce those inflated inventory levels, sightholders estimated. They’ve also shifted their production to lower-value goods to keep workers busy at a minimal investment, one India-based sightholder added.

As a result, De Beers’ sales declined 18% to $2.38 billion in the first half of 2019, while Alrosa’s rough sales fell 35% to $1.46 billion in the first five months of the year, according to Rapaport calculations.

Midstream pressure

Meanwhile, Cleaver also noted the challenging environment in China was affecting sentiment in the diamond market, while the US retail environment remained solid. Polished trading at the Hong Kong Jewellery & Gem Fair, which ended Sunday, was quiet, dealers noted. Attendance was down amid the mass protests that have taken place in the city during June, but also because Chinese buyers are not looking to make large purchases.

“People are hesitant to buy in a downward-trending market because they don’t yet see a bottom,” explained one Hong Kong-based polished dealer. “The mood is not good.”

US orders are more consistent, observed a Mumbai-based sightholder. US retailers are not making major orders, but he expects that will start to happen in the next month or two. Diamond trading generally remains quiet in July, when most US wholesalers close for the summer vacation.

“We expect the market will stabilize in late July,” he said. “But the problem isn’t from the retail side. It’s the business-to-business (B2B) trading that is low and the manufacturing sector that is under pressure. People don’t want to do business in the rough market.”

Tiffany Is Training Africans to Cut Diamonds Sourced From Region

Tiffany & Co. has been expanding its workforce in sub-Saharan Africa, a region of almost one billion people where the jewelry giant doesn’t have a single store.

More than a quarter of the New York based company’s 1,500 global diamond cutters and polishers are now based in Africa, Chief Executive Officer Alessandro Bogliolo said in an interview in Cape Town.

Tiffany has factories in Botswana and Mauritius with staff subject to “intensive training” over two years, he said, making it the only western luxury brand that doesn’t outsource production of its African stones.

Botswana is the world’s largest diamond producer after Russia, and is the only African country where Tiffany both buys and prepares its stones.

While it also sources diamonds from mines in South Africa, Namibia and Sierra Leone, it won’t do business in Zimbabwe and Angola because of the human-rights situation in those countries, Bogliolo said.

“If you buy from a world class brand, it’s because you trust that this brand has done all that is humanly possible to guarantee that the product is not only crafted to the highest standard, but also ethical and traceable in its manufacturing,’’ the CEO said.
Ethical Jewelry

The move to hire and train African polishers and cutters comes as Tiffany strives to be completely transparent about how its diamonds progress from deep underground to the engagement rings of wives to be. That’s in line with a wider trend in consumer goods industries to tap into demand for products that younger shoppers see as ethical.

This year, the company started to share the origin of its diamonds with customers, an initiative Bogliolo believes will push the entire industry to follow suit.

Tiffany has been trying to recoup sales that have been hit by a slowdown of Chinese tourist spending in the U.S., including an expansion of the business in Beijing and Shanghai.

While Bogliolo said the jeweler has a lot of customers in Africa, they’re forced to leave the continent to make purchases as the retailer’s only outlets there are in Egypt.

However, the CEO said South Africa is an “interesting market” where the company might eventually open at least one store.

“There’s no doubt that we will have a more robust presence on this continent,” he said. “It’s just a matter of finding the right location and the critical mass in order to have a sustainable business.”

Tiffany shares have gained 32 percent this year, valuing the company at $12.9 billion.

Lucapa Diamond announced a 90% upsurge in Diamond Resource Carats at Lulo

The international diamond group, Lucapa Diamond Company Limited has high valued mines in Angola and Lesotho, with exploration projects in Australia, Botswana, and Angola.

The company on 21 March 2019, provided an update on Alluvial Diamond Resource for the Lulo diamond mine in Angola Lulo Diamond Resource. LOM is under the partnership with Rosas & Petalas and Empresa Nacional de Diamantes E.P.

Z Star Mineral Resource Consultants Limited, an External consultant of Cape Town, South Africa, independently estimated and reconciled The Lulo Diamond Resource, on a depletion and addition basis as on December 31, 2018.

The resource estimation comprised of 19 months of mining depletion at Lulo from May 31, 2017, to December 31, 2018. During, 19 months, more than 30,000 carats of diamonds were recovered and sold for approximately US$ 62 Mn.

This extensive ongoing resource definition, drilling and sampling program included an additional 4,200 auger holes 36,000 meters drilled.

The current sale of Diamond was estimated at prices above the previous resource estimation on May 31, 2017.
