Botswana second huge diamond unearthed in a month

An exceptionally large and white 1,174 carat diamond stone has been unearthed in Botswana, trumping another huge precious stone that was found in the African country in June.

The latest find, which fills the palm of a large hand, was also discovered in June, on the 12th. It was found by the Canadian Diamond firm Lucara and presented to the country’s cabinet in Gaborone on Wednesday.

“This is history in the making, for us and Botswana as well,” said the company’s managing director, Naseem Lahri, adding that the diamond was in third position among the world’s largest gemstones.

On 1 June the Botswanan diamond firm Debswana said it had recovered what was then the “third largest” stone in the world, weighing in at 1,098 carats.

Botswana leads the world for the largest precious stones, accounting for six in the top 10 list. The country is Africa’s leading diamond producer.

The biggest diamond ever discovered anywhere was the 3,106 carat Cullinan, found in South Africa in 1905. Parts of that diamond adorn the British crown jewels.

Mokgweetsi Masisi, the president of Botswana, on Wednesday welcomed the “riveting moment” and the frequency of diamond discoveries in his country.

Lucara Recovers 1,174 Carat Diamond from the Karowe Mine in Botswana

Lucara Diamond Corp. is pleased to announce the recovery of a 1,174.76 carat diamond from its 100% owned Karowe Diamond Mine located in Botswana.

The diamond, measuring 77x55x33mm, is described as a clivage gem of variable quality with significant domains of high-quality white gem material, and was recovered from direct milling of ore sourced from the EM/PK(S) unit of the South Lobe.

The 1,174 carat diamond represents the third +1,000 carat diamond recovered from the South Lobe of the AK6 kimberlite since 2015 including the 1,758 carat Sewelô and 1,109 carat Lesedi La Rona.

The 1,174.76 carat diamond was recovered in the Mega Diamond Recovery XRT circuit. On the same production day, several other diamonds of similar appearance (471 carat, 218 carat, 159 carat) were recovered at the main XRT circuit, indicating the 1,174 diamond was part of a larger diamond with an estimated weight of > 2000 carats.

The MDR is positioned after the primary crusher, ahead of the autogenous mill, and is the first opportunity for diamond recovery within the circuit.

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.

Gem Diamonds ramps up production in Lesotho

Gem Diamonds announced Thursday that the company produced 29,010 carats at its Letšeng mine in Lesotho, which is 11% more than in Q1 2020 – 26,110 carats.

The company’s revenue for the period was US$43.9 million Q1 2020 – US$47.3 million and an average price achieved for the period was US$1,630 per carat Q1 2020 – US$1,615 per carat.

The company said that 5 diamonds sold for more than US$1.0 million each, generating revenue of US$12.4 million during the period.

The group ended the period with US$26.9 million of cash on hand excluding US$8.2 million of the March tender proceeds received after the period end. During the period, Letšeng paid the remaining dividend of US$10.0 million which was declared in 2020.

CEO Clifford Elphick commented, “It is pleasing to see that carat production during the period was up some 11% on the same period in 2020 and that the average price of US$1,630 per carat was also slightly up on Q1 2020. Although the production from the mining mix was not as impressive as the second half of 2020, with fewer large diamonds recovered due to the areas accessed under the mining plan, prices achieved on a like for like basis remained strong for Letšeng’s high value diamond production.”

The company said it anticipates that the mining mix should improve over the coming months as the richer parts of the Satellite pit are accessed in accordance with the mine plan.

Gem Diamonds is a leading global diamond producer of large high value diamonds. The company owns 70% of the Letšeng mine in Lesotho and is currently in the process of selling its 100% share of the Ghaghoo mine in Botswana. The Letšeng mine is famous for the production of large, exceptional white diamonds, making it the highest dollar per carat kimberlite diamond mine in the world.

Alrosa Raises Rough Prices Again

Alrosa has increased prices for the third consecutive contract sale, fueling concerns about unsustainable growth and tight manufacturing profits.

The adjustments were 4% to 5% on average, with a focus on 1-carat rough and larger, insiders told Rapaport News this week. Prices of that category are now higher than pre-pandemic levels, a customer noted.

Alrosa declined to comment on its “commercial strategy,” but a spokesperson said the Russian miner “assures that prices for its goods follow the real, confirmed demand from the midstream sector.”

The sale, which took place this week, came amid strong rough demand following positive holiday seasons in the US and China. But there were warnings of a slowdown as the quiet season approaches.

“Since the rough market is so strong, everyone accepts the [prices], but it’s becoming a bubble that might explode,” a source cautioned.

Industry members highlighted possible challenges for manufacturers. Rough prices have outpaced polished, they claimed, with the upcoming slow months raising concerns about end demand.

“[The miners have] taken away all the profit margin from the manufacturing pipeline, because…when the polished is ready, the polished market will be slightly weaker than today,” an Alrosa customer explained. “Probably, we will all lose some money, and not even make the costs.”

Alrosa maintained its policy of allowing customers to refuse any unwanted goods — a concession that has been in place since the start of the pandemic.

However, some clients felt compelled to buy to ensure they retain their allocations in the new contract period, which begins April 1, one customer pointed out. Even so, rough sales at the trading session will likely be lower than the $421 million it reported for January and the $361 million it garnered in February, reflecting a drop in the miner’s supply, he added.

De Beers: Less availability

De Beers will also offer limited supply at its sight next week as its reduced production plan for 2021 has affected availability. Sources expect sales of around $400 million, compared with $663 million in January and $550 million in February. The company lowered its full-year production forecast in January because of operational issues at some of its mines.

“We continue to take a prudent approach with our mine plans given the ongoing pandemic and associated uncertainty,” a De Beers spokesperson said Wednesday.

With fewer goods on the table, further price increases by De Beers are unlikely at next week’s sale, a sightholder predicted. The miner already increased prices in December, January and February, reversing a sharp price cut it implemented in August.

“There was a major pushback on the goods last month,” the sightholder commented. “In anything that [produces] pointers and large [polished goods], they went way too far, and everybody said so. There were also refusals. If [prices] go up now, everyone will just leave the goods.”

Beware a Supply Bottleneck

The positive sentiment the diamond market experienced during the past few months was a welcome change from the gloomy tone that characterized 2020. Buoyed by holiday sales that proved better than expected, the trade gained the confidence to buy again, even with activity limited mostly to online platforms.

For the first time in many years, polished suppliers struggled to fill orders due to shortages during the fourth quarter. Just a year earlier, the midstream was plagued by what seemed to be a chronic oversupply that pushed down polished prices and caused profit margins to tighten. Among the few benefits of the Covid-19 lockdowns was that manufacturers were forced to freeze rough purchases, stop production, and start depleting the excess inventory they had.

With fewer goods available, it was understandable that the rough market would wake up again in the fourth quarter. The resurgence was a remarkable one, too: The combined volume of De Beers’ and Alrosa’s rough sales rose 57% year on year to 23.9 million carats in the final three months of the year. That’s more carats in a quarter than the two have sold since the beginning of 2017 — itself an anomaly period that arguably fueled the ensuing oversupply crisis.

The positive momentum continued into the new year with reports of sizable rough sales last month. De Beers notched its largest sight in three years, while Petra Diamonds and Mountain Province continued to see good demand at their tender sales, with prices up 8%.

In the February issue of the Rapaport Research Report, we consider the question of whether the strong rough sales are a product of polished demand or of the low supply that typified the market earlier in 2020. It could be both. What’s certain is that the rough market must cool in the coming months or risk throwing the industry back into a polished-oversupply scenario.

Such an event would undo the hard work that went into restoring an equilibrium between the rough and polished markets. It would also fuel skepticism about the stated intention — by miners, manufacturers and retailers alike — of ensuring the diamond market becomes demand driven and more efficient in its operations.

Now, at the start of February 2021, the industry is at a crossroads. Manufacturers must curb their rough purchases to maintain the balance we’ve achieved in recent months and ensure a sustainable recovery. While the holiday season was relatively positive for the industry, global diamond jewelry sales have not yet returned to pre-pandemic levels and are unlikely to do so this year. For now, this means the recovery remains a supply-driven one, and the industry needs to walk the fine line between caution and its enthusiasm to do business again.

Mountain Province’s first diamond sale of 2021 shows 8% price rise

After a devastating 2020 which saw a near-collapse in the global diamond trade, Mountain Province Diamonds‘ latest sales figures show the sparkle may be starting to return to the diamond sector.

The 49% owner of the Gahcho Kué mine in the Northwest Territories, operated by 51% owner De Beers, sold 241,827 carats of diamonds for $21.8 million or $90 per carat in the sale, which closed on Jan. 22 in Antwerp. That represents an encouraging increase from an average sales price of $64 per carat in the final quarter of 2020 and $37 per carat in the third quarter.

“The first sale of the year was excellent, the growing confidence amongst rough diamond buyers translated into a healthy price improvement of 8% on a like for like basis when compared to our record high volume December sale,” said Mountain Province president and CEO, Stuart Brown, in a release. “We expect to see a continuation of the positive trend as rough and polished markets continue to strengthen post a successful retail season.”

The company’s next sale, in February, will include the 157-carat “Polaris” gem diamond, recovered in the fourth quarter. Named after the North Star, the stone appears colourless in daylight, but under ultraviolet light “exhibits a rare natural blue fluorescence that echoes its Arctic origins.”

Mountain Province recently released its production and sales results for the fourth quarter. Two confirmed cases of covid-19 during the quarter affected production as existing health and safety precautions were further enhanced. For the quarter, the operation saw a 12% decrease in total tonnes mined (ore and waste), a 21% decrease in tonnes treated (to 736,140 tonnes), and a 23% decline in carats recovered (to 1.5 million carats).

Mountain Province’s share of fourth-quarter production was nearly 745,600 carats.

For the year, the company recorded total sales of 3.3 million diamonds at an average price of $51 per carat for C$227 million ($171.3 million) in revenue.

“Under very difficult circumstances, all driven by Covid-19, the Gahcho Kué mine has performed well in being able to maintain production, albeit at a reduced level, and came very close to the revised guidance in tonnes mined and treated and exceeded the revised guidance target for carats recovered,” Brown said earlier this month on the release of the production figures. He added that the carat recovery was “particularly pleasing under the circumstances” and positioned the company for positive sales numbers in the first quarter of 2021.

Brown said that the last quarter of the year saw a “strong recovery” in the diamond market. In addition, the late 2020 closure of Rio Tinto‘s high-volume Argyle mine in Australia is expected to help establish a “more balanced” supply and demand equilibrium.

“The diamond market came under unprecedented pressure from early March to early September and although this pressure remains, we did see a strong recovery with respect to rough diamond demand in the last quarter of the year,” Brown said. “The two sales during the last quarter saw significant price recovery across all categories of diamonds sold. Early diamond jewelry retail sales reports are encouraging, and we expect to see steady demand for rough diamonds in the first quarter of 2021. There will no doubt still be challenges ahead but we are certainly more positive in our outlook as we start 2021 compared to the middle of 2020.”

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.”
