Alrosa to Sell 242ct. Rough Diamond

Alrosa will auction a 242.31-carat diamond in Dubai later this month, one of the largest gem-quality rough stones the Russian miner has unearthed in the past decade, it said Friday. The opening price will be in excess of $2 million.

The March 22 sale will mark Alrosa’s 100th large-diamond auction. The company rarely trades Russian-mined rough diamonds of this magnitude — those that can produce a 100-carat polished stone or larger — because the law grants the state the right to examine and buy them.

“Even when it is possible to put them on sale on the market, we prefer to cut and polish the diamond[s] in-house,” said Evgeny Agureev, Alrosa’s head of sales. “Thus, today we are especially pleased to present this exceptional lot as part of our 100th international auction.”

Viewings will take place at Alrosa’s sales office in Dubai from March 14 to 21. Rough diamonds weighing 190.74 and 136.21 carats will also be available, as will several other stones above 10.8 carats.

Lucapa recovers third 100+ carat diamond for 2021

114-carat white diamond recovered at Lulo

Lucapa Diamond Company has discovered a 114-carat white diamond from the Lulo alluvial diamond mine in Angola, Africa.

The 114-carat Type IIa D-colour white diamond is the third diamond mined from Lulo’s mining block 46 (MB46) in the last eight weeks.

Lucapa managing director Stephen Wetherall said block 46 was the best mined block to date.

Lucapa stated that the new discovery demonstrated the value of Lulo’s Canguige catchment and its adjacent kimberlites.

“To date, MB46 has averaged one 100-plus carat diamond recovered for every ~33,000 billion cubic metres of gravel processed. This is the best occurrence rate for any block mined to date at Lulo, including the prolific MB08,” Lucapa stated.

The 114 carat diamond is the 19th 100-plus carat diamond recovered from Lulo.

Lucapa started commercial diamond production at the site in 2015.

The recovery follows Lucapa’s announcement of discovering a 215-carat diamond from its Mothae kimberlite mine in Lesotho, Africa this week.

Lucapa plans to expand Mothae to a 1.6 million tonnes a year processing capacity, a 45 per cent increase from its current rate.

Lucapa’s Lulo diamonds fetch US$5.9 million

Lucapa Diamond Company and its partners have announced the results of the first diamond sale of 2021 by Sociedade Mineria Do Lulo (SML) from its Lulo alluvial mine in Angola.

The rough diamond parcel of 4,273 carats was sold for a total of US$5.9 million (A$7.7 million) or US$1,375 (A$1,793) per carat.

Lucapa MD, Stephen Wetherall comments: “As with the first sale of Mothae diamonds in 2021, prices achieved by SML at this sale continued to reflect the positive industry mood, and with sales from both operations in 2021 already totalling A$15 million, it has been a solid start to the year.”

Tax Authorities to Return a Million Rough Diamonds from Raids

A million rough diamonds seized in raids by the Indian tax authorities on the scanning firm Diyora & Bhanderi are to be returned to their owners.

The company is being investigated over claims of tax evasion and the illegal sale of diamond scanning machines. Its premises in Surat were raided 10 days ago.

Gems belonging to over 800 diamond firms, which had been sent to Diyora & Bhanderi Corporation (DBC) for rough scanning, were seized, along with large quantities of cash.

The Surat income tax authorities responded on Friday to representations by the Southern Gujarat Chamber of Commerce and Industry that diamantaires should have their gems returned, as long as they can provide the proper paperwork.

Meanwhile, Sarine, the Israel-based diamond tech firm, accuses DBC of copying the industry-standard Galaxy inclusion mapping software used by its rough diamond scanning machines and is taking action through the High Court of Gujarat, in Ahmedabad.

Bristow to finally put Rockwell Diamonds saga to bed after firm unveils wind-up plan

MARK Bristow, CEO of Barrick Gold Corporation, is to finally close the book on Rockwell Diamonds, a company he chaired and which he once attempted to save from bankruptcy.

Rockwell Diamonds announced today the Canadian listing authority had revoked a cease trade order which had been issued as the company had previously failed to produce quarterly numbers with the accompanying management discussion.

The company today filed third quarter numbers and announced its intention to wind up its affairs in which a company owned by Bristow, ‘Bristco’ would mop up the interests of minority shareholders in Rockwell and put them into ‘Amalco’.

Dissenting shareholders would have their interests exchanged on a one-for-one basis for redeemable preference shares of Amalco.

The redeemable preference shares would then be immediately redeemed by Amalco in exchange for half a Canadian cent per share, payable in cash. A meeting of shareholders requiring a simple majority has been arranged for March 2.

Bristow first sought to bail out Rockwell Diamonds, which was once run by his brother, John Bristow, in 2014, in which Mark Bristow bought $1.1m in debentures. In 2016, Bristow embarked on a process of ‘fumigation’ in which he restructured the firm’s board and conducted an overview of its operating activities.

Unfortunately, the company never managed to gain traction at its key asset, the 200,000 cubic metres a month Wouterspan, situated in the alluvial diamond fields region of the Northern Cape province.

There was a proposed $8m recapitalisation of the company in 2017.

The company was subsequently put into liquidation proceedings following attempts by a business practitioner to save it from failure. The company was in and out of court throughout this period with claims of corruption involving contractors.

In 2019, Bristow completed the merger of his Randgold Resources with Barrick Gold, a fabulously successful transaction which as coincided with high gold prices.

Lucara recovers 341 carat white diamond

341 carat white diamond found at the Karowe mine in Botswana

Canada’s Lucara Diamond has found an unbroken 341-carat white gem-quality rock at its prolific Karowe mine in Botswana, with analysts estimating it could fetch more than $10 million.

The Vancouver based miner said the diamond was recovered over the Christmas period from milling of ore coming from the south western quadrant of Karowe’s South Lobe.

The diamond is the 54th stone over 200 carats recovered at Karowe since it began commercial operations in 2012.

The find builds on previous historic recoveries which include the 342-carat Queen of the Kalahari, the 549 carat Sethunya, the 1,109 carat Lesedi La Rona found in 2015, and the 1758 carat Sewelô, recovered in 2019.

Beyond Sewelô, the only larger diamond ever unearthed is the 3,106 carat Cullinan Diamond, discovered in South Africa in 1905. The Cullinan was later cut into smaller stones, some of which now form part of British royal family’s crown jewels.

Petra Diamonds’ investors back restructuring

Petra Diamond’s Finsch mine in South Africa

Struggling Petra Diamonds (LON: PDL) said on Wednesday its investors have approved plans to restructure the business, a move that aims to provide the miner with a more stable, deleveraged capital structure to ensure its short and long-term viability.

Over 95% of shareholders voted in favour of a resolution that includes reducing authorized share capital of the company by cutting the nominal value of all ordinary shares from 10p to 0.001p.

SIGN UP FOR THE PRECIOUS METALS DIGEST
It also involves an increase to Petra’s authorized share capital through the creation of 8.5-million ordinary shares and the authorization for directors to allot ordinary shares up to £88,447 ( just over 8.8-million ordinary shares).

Hefty debt
Petra Diamonds’ weak financial position, a product of stagnant demand and heavy borrowing to expand its mines, particularly the iconic Cullinan, pushed it to put itself up for sale in June. Petra reversed the decision in October, opting instead for the debt-for-equity restructuring approved Wednesday.

The company noted it expected to complete the reorganization in the first quarter of 2021.

Petra’s shares slumped by more than 80% last year as the covid-19 pandemic battered the global diamond sector, with mines forced to shut down while consumer demand continued to fall.

The diamond miner, which has three operations in South Africa and one in Tanzania, is also dealing with allegations of human rights abuses at its Williamson mine in Tanzania, resulting from the actions of its security guards.

De Beers Trims Production Plan for Coming Years

De Beers has reduced its production plan for the next two years, aiming to avoid releasing too much rough into the market as the diamond sector attempts to exit the crisis that dominated 2020.

The miner expects to unearth 33 million to 35 million carats in 2021, down from its previous forecast of 34 million to 36 million carats, parent company Anglo American said Friday in a presentation to investors. Output in 2022 will range from 30 million to 33 million carats — compared with earlier guidance of 33 million to 35 million carats — and will remain at the same level in 2023.

De Beers will produce around 26 million carats this year, after the pandemic prompted management to rethink the previous outlook of 32 million to 34 million carats.

“There’s an appropriate degree of prudence being exercised in what we’re forecasting going forward, and we certainly aren’t going to be a contributor to overstocking across the industry now,” said Anglo American CEO Mark Cutifani. “Given the supply situation, we’re going to watch that very carefully. We won’t push more production out there unless we’re comfortable prices are going to increase.”

The adjusted figures came despite De Beers’ expectations of limited global supply, with around 30 million carats dropping out of the pipeline as a result of Covid-19 and the closure of the Argyle mine, he estimated. At least two-thirds of that is unlikely to come back into the market, the executive pointed out. Meanwhile, Cutifani noted signs of a recovery in demand after a difficult year for the industry.

“[It’s] a bit early to call how the Thanksgiving [to] New Year selling season will go, but so far [it’s] quite encouraging despite the obvious Covid issues in the US,” he explained. “China’s been very strong. So far, things are going pretty well.”

However, caution is necessary following a string of major internal and external events that have derailed the diamond market in recent years. Those include a credit crisis in the Indian market in 2018, as well as the US government shutdown that occurred in late 2018 and early 2019, the CEO warned.

Separately, De Beers has made an advance purchase of rough from Debswana, its joint venture with the Botswana government, providing the company with inventory to sell in the first quarter if the demand recovery continues. It also received a one-year extension to negotiations with the African country over their sales deal, after the pandemic prevented the parties from reaching an agreement this year. The 10-year arrangement was due to expire on December 31, 2020.

Lucapa 100 carat diamond bonanza continues

Lucapa Diamond Company has recovered the 16th 100 plus carat diamond from the Lulo alluvial mine in Angola, Africa.

The 127 carat gem quality white stone is the third 100 plus carat diamond delivered this year.

Lucapa recovered the stone from the flood plain area in Mining Block 24 the first 100 plus carat diamond produced in this mining block.

It was found during Lucapa’s dry season operations.

“The recovery of this 127 carat stone, which is Lulo’s 16th 100 plus carat diamond recovered, continues to showcase the exceptional nature of the lulo alluvial deposit and highlights the potential of the mining campaign planned for these previously untouched and expansive leziria areas along the Cacuilo River,” Lucapa managing director Stephen Wetherall said.

The discovery was preceded by a 46 carat pink coloured diamond recovered at the Lulo mine last week. It was cut and polished into three diamonds.

Meanwhile, the largest stone in carat found at Lulo was a 404 carat diamond the largest recorded gem in Angola, which was discovered in 2016.

Synova’s Automated Cutter to Tackle Fancy Shapes

Swiss technology provider Synova has expanded its automated diamond-cutting system to include fancy shapes, it said Monday.

The company, which is part-owned by De Beers, unveiled the DaVinci Diamond Factory last year at the Dubai Diamond Conference. Synova claims the machine will significantly speed up diamond manufacturing from weeks to hours, improve accuracy and symmetry, and reduce costs. However, the version it initially launched could only cut round-brilliant diamonds with up to 57 facets.

“The pandemic restrictions had us more or less blocked from selling in the first half, so instead of sitting here and doing nothing, we developed the machine and made it market-ready,” Joerg Pausch, head of the diamond business at Synova, told Rapaport News. “We developed software add-ons that will allow for cutting of automated fancy shapes. After the first announcement, people were calling us asking if it can do fancy shapes, and that has actually become our strongest request from the market.”

Synova’s initial testing of the automated fancy shapes has shown “very promising results,” it noted. The technology provider will release the new software early next year.

The company has already received a number of orders for the DaVinci from Europe, South Africa and North America, Pausch noted. It also intends to develop the machines to include more automation, he added.
