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.”
