Threat of synthetics is an opportunity for diamond traceability

The Namibia Desert Diamonds General Manager of Sales and Marketing, Lelly Usiku, said the threat of synthetic diamonds has brought about an opportunity in the diamond industry to focus on the traceability of the precious stones to verify diamond origins from the mines to jewellery.

Usiku expressed these sentiments during a panel discussion on the diamond industry and its associated value chains. She further outlined that Covid-19 forced Namdia to investigate the possibilities of online trading in order to replicate the physical viewing with a virtual viewing experience.

Chief Executive Officer of Namdia, Kennedy Hamutenya, said in protecting the image of diamonds, the industry made a commitment in 2008 on the number of producers and manufacturers through the Kimberly Process. He said the process helped squeeze out undesirable elements from the diamond business.

According to Hamutenya, trading partnered states agreed to create a menu for the world and buyers that ensured diamonds on the market would not be associated with conflict diamonds. Conflict diamonds are diamonds mined in a war zone and sold to finance an insurgency, an invading army’s war efforts, or warlord activities.
“So, we said every country must implement systems and procedures from the very starting point of mining to the point of export to ensure that there is no penetration of conflict diamonds.

Today, as we speak, 99.8% of all our diamonds are clean, thanks to the Kimberly Process. We have done everything possible to prevent conflict diamonds to penetrate our pipeline,” Hamutenya stated.

According to him, Namdeb Holdings has spent N$3 billion on local procurement of goods and services for the last financial year.
Also, at the same occasion, Brent Eiseb, CEO of the Namibia Diamond Trading Company, elaborated on their mandate and said they sort and value diamonds. He noted that the process entails highly skilled employees as well as technology.
He added that whether diamond mining happens on land or offshore, the value is only confirmed when the stones go through NDTC’s evaluation process.

“This is an important process as it determines the value of royalties and taxes that is to be paid by producers to the government. Another mandate is to facilitate downstream diamond beneficiation.
We take about N$430 million in indexed diamonds and make them available for value addition in Namibia,” explained Eiseb.
He added that this process is vital because it requires quality infrastructure, especially in Namibia, for cutting and polishing of diamonds and also for creating the most job opportunities.

Eiseb concluded that the diamond industry is important in providing for the country at large through development diamonds. He indicated that 85% of total revenue that is created through the sales of diamonds ends up in state coffers through royalties, taxes, and levies that are payable and dividends.

Star Diamond recovers 2,409 diamonds in second bulk sample

Star Diamond Corp announced that a total A total of 2,409 diamonds weighing 123.27 carats have to date been recovered from the second bulk sample trench (19FALCT004) excavated on its Star kimberlite at the Fort à la Corne kimberlite field in central Saskatchewan.

These initial results are from the second of 10 bulk sample trenches excavated by 60% optionee Rio Tinto Exploration Canada Inc in 2019.

The average diamond grades from the first two trenches are similar to historical diamond grade results detected from the underground bulk sampling and large diameter drilling completed on the Star kimberlite between 2004 and 2009. These results are also similar to the overall weighted average grade 14 carats per hundred tonnes reported in Star Diamond’s PEA of the Star and Orion South kimberlites .

The three largest diamonds recovered to date from 19FALCT004 are 2.98, 2.03 and 1.99 carats, respectively, and were all recovered from Early Joli Fou kimberlite. The EJF is the dominant kimberlite unit within the project in terms of ore volume and diamond grade.

As disclosed by Star Diamond on August 4, 2020, there are indications that recent diamond breakage has occurred in the diamond parcels recovered thus far from RTEC’s trench cutter bulk sampling program, suggesting that the extraction and/or processing systems being used by RTEC may be resulting in diamond breakage. Comprehensive diamond breakage studies are required to assess the nature and extent of the diamond breakage resulting from RTEC’s methods and the possibility that larger diamonds would have been recovered absent such breakage.

Senior vice president of exploration and development, George Read, states: “The initial diamond results from 19FALCT004 and 19FALCT001 continue to show grades similar to the previous underground bulk sampling and LDD performed by Star Diamond on the Star kimberlite. Individual EJF kimberlite samples recovered in the first two trenches exhibit a range of grades 9.81 to 21.22 cpht for 19FALCT004 and 4.88 to 23.34 cpht for 19FALCT001, which are as expected for the EJF kimberlite.”

Southstone Minerals recovers many large, high quality diamonds

Southstone Minerals Ltd. [SML-TSXV] provided a production and operational update for December 1, 2019, to February 28, 2020 (Q2 2020), and March 1 to May 31, 2020 (Q3 2020), on its project portfolio in South Africa.

The Oena Project consists of one New Order Mining Lease located in the Northern Cape Province, South Africa. Oena is 8,800 hectares in size and covers a 4.8-km wide strip along a 15-km length of the lower Orange River. Southstone owns 43% of African Star Minerals (Pty) Limited which owns 100% of the property.

Southstone continues to focus and prioritize its efforts on the alluvial Oena diamond mine. There is currently one mining contractor on site using eight pan plants to process run-of-mine (ROM) material and one Bourevestnik (BVX) unit used for diamond recovery.

Production results for both Q1 and Q2 were impacted as a result of the mandatory closure of the mine for the period from March 26, 2020, to May 3, 2020, due to COVID-19. A total of 803.92 carats (112 diamonds) were produced, placed on tender and sold with an average price of US $1,957 per carat.

Dominion Diamond unveils plan to avoid bankruptcy

Canada’s Dominion Diamond Mines has unveiled a transaction that would allow it to exit court protection from creditors and access short-term operating funds, which would pave the way to eventually restart its idled Ekati mine in Canada’s Northwest Territories.

The company, which owns and operates the iconic Ekati diamond mine and also has a 40% interest in the nearby Diavik, said it had signed a letter of intent with an affiliate of The Washington Companies.

The privately held Montana-based conglomerate bought Dominion for $1.2 billion in 2017 when the miner was the world’s third-largest producer of rough diamonds by value.

Under the agreement, which requires court approval, Washington would buy the company’s assets for about $177 million, while assuming its operating liabilities.

It would also provide Dominion with up to $84 million in short-term debtor-in-possession financing.

Ekati has been halted since March to help slow down the spread of the coronavirus pandemic. The operation was left with about $180 million worth of inventory, which it has been unable to sell since its Belgian retailers remain closed.

The diamond miner said at the time that covid-19 had a “devastating impact” on the global diamond mining industry, affecting the company.

According to court documents seeking bankruptcy protection from creditors, Dominion revenue from diamond sales last year reached about $528 million.

The company said the proposed sale would be conditional on reaching an agreement with Rio Tinto on the Diavik joint venture. Failing that, Dominion would exclude its interest in the Yellowknife diamond mine from the transaction.

The miner is a major employer in the Northwest Territories, with 634 workers, 60% of whom are locals. Only 212 people are currently at the mines, which are fly-in and fly-out operations. This allows for a pre-screening of the staff before they are allowed to board flights to Ekati and Diavik.

Shattered dreams

The global coronavirus outbreak squashed diamond miners’ dawning hopes of a recovery in a sector already reeling from weak prices and demand since late 2018.

De Beers, the world’s largest producer by value, cut 2020 production guidance by a fifth last month after earlier cancelling its April sales event.

Russia’s Alrosa, the world’s top diamond producer by output, saw sales for rough and polished diamonds drop to $15.6 million. The figure stood in stark contrast to the $152.8 million the diamond miner fetched in March and the $405 million in January.

Lucara Diamond, another Canadian company, posted earlier this month a net loss of $3.2 million, or $0.01 a share, for the first three months of the year.

The figure was in sharp contrast with the $7.4 million in net income, or $0.02 in earning per share the miner reported in the same period last year.

South Africa’s Petra Diamonds recently delayed interest payments to borrow $21 million in new debt, a crucial move to keep the company afloat.

Investment banks are increasingly reluctant to extend credit to diamond producers, as inventory is not being sold and defaults are possible, analysts have warned.

“We are concerned about an oversupply of rough diamonds following the reopening of economies, as a lot of inventory could potentially be flooded into the system and the market might not be able to absorb all of it, resulting in increased pricing pressure,” Citi said in an early May note.

Zimbabwe’s ZCDC Sets Sight On Doubling Diamond Production

The Zimbabwe Consolidated Diamond Mining Company (ZCDC) failed to meet its 2019 target of 3 million carats, but officials are buoyant fortunes will turn around as the firm has consolidated its investments in exploration, mining and processing to improve output this year.

Speaking durng a media tour of Chiadzwa diamond fields on Friday last week, Acting ZCDC Chief Executive Officer Roberto DePreto said they are aiming to double the 1.6 million carats produced last year through joint venture agreements, increased exploration as well as mitigating viability challenges, linked to power shortages and access to foreign currency.

“Since the Diamond Policy was issued we are now looking for joint venture partners, those joint venture partners get allocated a particular concession and we then subdivide the (overall) 626 special grant into specific special grants for those venture companies.

“Last year we produced 1.6 million carats and this year we are targeting to double that through our investments in new plant machinery and our exploration capabilities,” said DePreto.

Consuming an average of 5 megawatts and at 25 000 of diesel daily, ZCDC has also invested in new plant machinery from Belarus which needs foreign currency for repair and maintenance, with at least seventy percent of consumables and spares imported.

Officials said such overheads have hampered production targets, costing in total a minimum of 8 million tons of unprocessed diamond ore from the down time caused by the listed operation constrains.

Mine manager, Innocent Guvakuva said focus will be placed on optimizing processing capacity, already on a positive trajectory following acquisition of new plant machinery, as well as improving power supply to reduce production downtime.

“Last year there were issues to do with power, this year there has been a bit of improvement but last year it was worse, issues to do with fuel and general forex availability because 70 percent of all consumables and spares we import.

“So, if your foreign currency access scenario is not stable you are bound to suffer, but this year things have started on a better note… one of the biggest challenges in Zimbabwe is that we are a cash economy.

“We lost a lot last year in terms of production down time we lost, probably in terms of total material mined we are looking at about 8 million tones that we could have moved last year, which is very big,” said Guvakuva.

He added, “We have installed a 450 ton per hour plant it’s got phases now we are installing phase three where carat production is expected to go up, our focus now in terms of mining we are stable but it’s the liberation and optimization of the plant that we will work on.”

Guvakuva said focus will also be placed on greenfield and ground field, together with exploration contractors under a ‘hybrid exploration model’ in the seven approved special grants in regions considered diamondiferous.

“We are increasing our exploration through a hybrid model in the sense that we have our own exploration drill rigs, commissioned them in 2018, they are called diamond drill rigs that can drill up to 250 metres, we have what we call a Reverse Circulation Rigs (RCO).

“We have also engaged contractors which makes it the hybrid model, they have done work right now the contract has ended, but we are doing a lot of exploration we have a lot of ground field and greenfield projects all over the place.

“ZCDC we have seven approved special grants, in this whole area which is about 26 to 30 kilometers its assumed to be diamondiferous, but the economics of it is what we do through exploration. To say we will be here for two or three years I will be lying (is an under estimation) but we will be here for a very long time,” said Guvakuva.

BlueRock Diamonds Reports Profitability

BlueRock Diamonds has announced that it operated profitably for the first time in the second half of 2019. The miner started operations in 2012.

The AIM-listed diamond producer, which owns and operates the Kareevlei Diamond

Mine in the Kimberley region of South Africa said its revenue was up 190 percent to Â£4.1 million ($5.4 million) for full year 2019.

The miner sold 12,675 for the year, an increase of 118 percent over the 5,805 carats in 2018. On a quarterly basis, Q4 2019 saw an increase of 172 percent to 4,170 carats compared to 1,533 carats in Q4 2018.

BlueRock also saw an increase in its average price per carat during Q4 and FY2019. For 2019, the per-carat price increased 24 percent to $415 (2018: $334) and for the quarter it rose 30 percent to $410 (2018: $316).

“I am very pleased with the continued success at Kareevlei,” said Mike Houston, BlueRock executive chairman. “Having achieved the aggressive guidance for 2019 and operated profitably for the first time in the second half of 2019. We are proud of this key milestone, which is a testament to the implementation of the revised production strategy brought in by the company’s new management team in Q2 2019.”

BlueRock said it expects to report positive EBITDA and positive comprehensive income for

the second half of 2019 (excluding non-cash adjustments for IFRS 9 charges and movement in foreign exchange).

The company said the first quarter of 2020 has started “satisfactorily” with expectations that, despite the impact of seasonal rains, it will meet its targeted production volumes for the quarter, which are significantly ahead of those achieved in Q1 2019.

Perth Mint highlights rare Argyle diamonds

The Perth Mint has released Jewelled Tiger coins featuring rare pink diamonds from Rio Tinto’s Argyle mine in Western Australia.

Its most significant release for 2020 incorporates nearly three carats of fancy vivid intense pink diamonds from the Argyle mine, making up a finely structured three-dimensional 18 carat rose gold tiger pavé.

Two emeralds from Colombia’s Muzo mines feature as the tiger’s eyes and the coin is crafted from 10 ounces of 99.99 per cent pure gold.

The Perth Mint only issued eight Jewelled Tiger coins, which are priced at $259,000 each, recognising the significance of the number eight in Asian cultures and its association with luck and prosperity.

Renowned for its power and beauty, the tiger shares the symbolic virtues of gold and so it was a natural choice to feature the revered creature on a sophisticated release, according to Perth Mint chief executive Richard Hayes.

“Our 2018 Jewelled Phoenix and 2019 Jewelled Dragon coins sold out within weeks of their respective release dates. We expect the Jewelled Tiger will be similarly sought-after among the world’s diamond connoisseurs and collectors of luxury items,” he said.

Each Jewelled Tiger coin is presented in a display case with 18 carat gold furnishings inset with two additional Argyle pink diamonds.

The diamond dream is over: Rosendorff jewellers goes into administration

More than 110,000 Western Australian couples have celebrated a special occasion featuring a piece of Rosendorff’s fine jewellery.

An announcement to the Australian Securities and Investments Commission (ASIC) said a meeting of creditors was set to get under way at 11am Thursday.

Richard Tucker of KordaMentha Restructuring, appointed receivers and managers of Rosendorff Diamond Jewellers, said the business was holding too much stock.

“We are running a short highly discounted sale through the store to materially reduce the current stock levels whilst a sale or recapitalisation of the business is pursued,” Mr Tucker said.

I have always loved the mystique of diamonds. I’m attracted to the joy and romance they bring to their beholders

Craig Rosendorff
“It is a tremendous opportunity to acquire a very special jewellery item at very competitive prices and may also help save an iconic Perth jeweller.”

He said a secured creditor would support the receivers to ensure current special orders, repairs and lay-bys were completed in time for the special occasions they might be destined for.

“From proposals, to weddings and anniversaries, we understand the importance and significance these items have on people’s special memories,” Mr Tucker said.

Daniel Hillston Woodhouse of FTI Consulting has been appointed as administrator.

Rosendorff is an iconic West Australian luxury business specialising in diamonds and bespoke jewellery design headed by Craig Rosendorff.

In 1975 Mr Rosendorff renamed and launched what became one of the longest-standing diamond companies in Australia.

His rags to riches story has been dubbed The Diamond Dream.

“I have always loved the mystique of diamonds,” he says on the company’s website.

“I’m attracted to the joy and romance they bring to their beholders, the heritage and their connection to families across generations.”

The large, glamorous showroom in the centre of Perth on Hay Street has been the setting of many magnificent parties and events showcasing the designs of the Rosendorff team.

Mr Tucker said gift cards and store credits would be honoured while trade continues.

White knight rescues collapased Rosendorff Diamond Jewellers

The Rosendorff fine jewellery business will carry on but under new ownership following a deal struck by receivers appointed last month.

Insolvency firm KordaMentha confirmed today it had struck an agreement to sell the business set up by Craig Rosendorff in the 1980s to an unidentified WA buyer also involved in the jewellery trade.

The deal, expected to be finalised in two to three weeks, guarantees more than 20 jobs and covers the Rosendorff trading name, stock and intellectual property.

Receivers from KordaMentha were put into Rosendorff Diamond Jewellers at the end of April.

The business, which owes at least $4 million to creditors, has shrunk on falling sales in the past three years to just its flagship store in Hay Street Mall.

The deal covers the Rosendorff trading name, stock and intellectual property.

Today’s sale announcement coincided with news the receivers are stepping up a discount sale which has already brought in between $2 million and $3 million.

The West Australian revealed yesterday that administrators from FTI Consulting had identified “irregularities” in the company’s accounts while sheeting home blame for the collapse to the mining downturn.

They questioned a $1.8 million shortfall in stock and four transactions totalling $170,000 where jewellery “left the store without payment”.

FTI said “there were limited controls around the accounting and inventory functions, which have led to some anomalies in the financial accounts”.

However, it noted that such irregularities were not uncommon, and there is no suggestion of any wrongdoing by Mr Rosendorff.

The firm’s statutory report on Rosendorffs also noted that Mr Rosendorff, who has invested millions of dollars in the business over the past 30 years, had drawn increasing amounts out of the company as its financial situation deteriorated.

Between July 2017 and FTI’s appointment, those withdrawals totalled $1.8 million, including $582,000 in the past 10 months.

The administrators says Rosendorffs had been under financial pressure for two years, citing “cash leakage” and a steady decline in sales after 2011, triggered by the end of the mining boom.

Gordon Brothers is owed about $2.2 million, Rosendorffs’ staff $400,000 and trade creditors $270,000.

Last kimberlite trucked to plant at De Beers Victor mine

The last truckload of kimberlite from Ontario’s first and only diamond mine has left the pit. De Beers Canada said mining ceased on March 5 – 11 years to the day after the official opening in 2008.

The honour of driving the last truck went to Nancy Wesley, of Kashechewan First Nation. She worked at Victor for 11 years, as a haul truck driver, dozer operator and production drill operator.

Stockpiled kimberlite will keep the recovery plant running until early May.

The Victor mine was forecast to produce 6 million carats of diamonds over its life, but it beat that by recovering a total of 8 million carats – with a record 936,000 carats produced in 2018.

The project provided about 1,360 jobs and $3.7 billion of revenue to the province.

Lucapa to Sell Large Stones

Lucapa Diamond Company will sell six large stones weighing a total of 449 carats from its Lulo mine in Angola after an overhaul of the nation’s mining laws prompted it to delay the sale, it said.

The Angolan government introduced reforms to its diamond sector in the first half of the year to help boost foreign investment. Those measures included a new marketing policy for Angolan diamonds, and the option of offering goods for sale in locations such as Antwerp.

Anticipating the changes, Lucapa has been holding back a selection of large stones from previous sales, and will now sell them under the new policy, it explained Friday. These include six type IIa white diamonds weighing 114 carats, 85 carats, 75 carats, 70 carats, 62 carats and 43 carats, as well as a 46-carat pink diamond.

“The discussions with our Angolan partners regarding the policy changes taking place in the Angolan diamond sector have reached a stage where we are now able to plan for the sale of these large, premium-value Lulo diamonds held over from previous sales,” Lucapa managing director Stephen Wetherall said. “We look forward to marketing these exceptional diamonds as soon as the necessary arrangements are put in place to continue showcasing Angolan diamonds to the world.”

The decision to delay the tender for those stones had a negative impact on Lucapa’s first-half results, the company added. Its losses grew to $4.6 million for the period, versus a loss of $1.2 million a year earlier.

Even so, Lucapa’s sales rose 3% year on year to $15.9 million in the first half, while production for the same period climbed 15% to 9,566 carats. The average price of rough diamonds from Lulo rose 1% to $1,642 per carat. Rough-diamond inventory from the asset grew 61% year on year to 2,755 carats as of June 30, the miner reported.

Lucapa’s most recent sale of 2,531 carats of rough from Lulo fetched $2.5 million, achieving an average price of $985 per carat, the company noted.
