30 years of Ekati diamonds, 30 years more

In its first full year as the operator of the world-class Ekati diamond mine, Burgundy Diamond Mines Ltd. marked several milestones, including consistent diamond recoveries and advancements in extending the mine’s future, reinforcing its position as a prominent player in the Canadian diamond industry while laying the groundwork for continued growth and success.

Over the past year, Burgundy worked to solidify its position as the new operator of the Ekati diamond mine by focusing on improving production and extending the mine’s lifespan. This was reflected in the consistent quarterly performance throughout the year, despite challenges in the diamond market.

“Despite suppressed diamond market prices, we remain optimistic as supply-demand tightens and look forward to launching Ekati’s tenth mine – a landmark achievement,” said Burgundy Diamond Mines CEO Kim Truter.

In less than two years, Burgundy moved quickly to expand Ekati’s capabilities, advancing beyond initial stabilization to actively pursue new development and growth. This is exemplified by the development of the Point Lake open-pit project, which is set to become Ekati’s tenth operational mine.

This quickly became a critical component of the company’s strategy to secure long-term production at Ekati. With initial production planned in late 2024, Point Lake holds more than just increased production potential but also historical significance as the first diamondiferous kimberlite discovery in Northwest Territories – which led to the eventual development of Ekati.

Burgundy Diamond Mines Ltd.

Located approximately three kilometers northeast of the main mine camp, Point Lake, evidenced by its name previously existed as a natural lake, which required draining before mining operations could begin. Dewatered in two phases, and as part of the process, a total of 523 lake trout and 6,348 slimy sculpins were relocated prior to emptying the habitat.

The water was then pumped into the King Pond Settling Facility and Lynx pit, allowing suspended solids to settle and facilitating future underwater remote mining trials at Lynx pit.

Currently, Ekati is estimated to contain approximately 140 million carats of diamonds in the indicated category, even after more than 26 years of production. These remaining resources are concentrated within the currently active Misery underground and Sable open-pit mines, with Point Lake projected to add an estimated 5.3 million carats once it begins production, further bolstering Ekati’s resource base.

This robust resource position led to a major milestone in late October, as Burgundy celebrated Ekati reaching 100 million carats of diamonds recovered – a testament to the mine’s enduring contribution to the diamond industry.

“As we reflect on this historic achievement, Ekati continues the legacy as one of the premier diamond assets in the world in a tier one location producing highly sought after sustainably and ethically produced diamonds for the global market,” said Truter.

With substantial reserves still available, Ekati is well-positioned for another 30 years of production, potentially even longer if further resources are identified.

“We are proud of the team we have in place and of everything we have achieved so far,” Truter added. “Ekati still has 140 million carats remaining in Indicated Mineral Resources, one of the largest unmined diamond endowments in the world, which provides Burgundy shareholders an indication of Ekati’s remaining mine life potential.”

Beyond Point Lake, Burgundy has also focused on extending the mine life of other key operations at Ekati. In particular, the Misery underground mine has shown promise for extended production through recent exploration efforts.

Looking ahead into 2025, Burgundy continues to focus on operational efficiency and advancing exploration to maximize Ekati’s resource base.

With production at Point Lake expected to commence and further drilling at Misery ongoing, Burgundy is executing its strategic plan to secure sustained production at Ekati.

The company is also progressing feasibility studies for additional underground sites, all aimed at maintaining Ekati’s position as a key contributor to the global diamond market, while delivering value for shareholders and supporting local communities in the Northwest Territories.

Mountain Province Losses Increase in "Challenging Market"

Mountain Province reported increased net losses for the latest quarter as prices keep on dropping in a “challenging market”.

The Canadian miner today (7 November) announced a net loss of $13.6m for the three months to 30 September, following on from a $4.7m loss in Q2 (all figures are in US dollars).

“In Q3 2024 our sales achieved 100 per cent sell-through with no unsold stock held at the end of September and a higher average selling price than the three preceding quarters,” said Reid Mackie, VP sales and marketing at Mountain Province.

The average price per carat was, however, down 21 per cent on a year ago – from $95 to $75.

The company sold a 679,599 carats were sold for $50.8m, compared to 478,653 carats in Q3 2023 for $45.3m. Year-on-year the number of carats sold was up almost 30 per cent, but revenue increased by just 12 per cent.

Adjusted EBITDA was $12.5m and loss from mine operations was $8m.

As for operations at the Gahcho Kue mine (pictured), the number of tonnes of ore treated increased 10 per cent year-on-year, but the number of carats recovered fell by 10 per cent.

CEO Mark Wall explained that this was “driven by planned lower grade in Q3 and unplanned lower grade in March and early Q2 of 2024”.

He said that while the diamond market had been disappointing, he was optimistic that the price environment would recover during 2025 and that it would be followed by a very strong production year in 2026.

Rio Tinto offers early termination to Diavik employees to save costs

Rio Tinto is offering early termination for employees at its Diavik diamond mine as part of the company’s efforts to save costs ahead of the mine’s closure in 2026, the Australian miner told jewelry news agency Rapaport.

Located in Canada’s Northwest Territories, about 200 km south of the Arctic Circle, Diavik has become an integral part of the NWT economy, employing over 1,000 people and producing an average of 6-7 million carats of gem-quality diamonds annually.

Since entering production in 2003, the mine has outputted roughly 90 million carats of rough diamonds, making it one of the largest in Canada.

The offer of early termination to Diavik employees, says Rio Tinto, is a response to the challenges currently facing the diamond industry as the mine approaches the end of its life cycle.

“I can confirm that Diavik is looking at voluntary separation as part of our efforts to manage costs and rightsize our business given the relatively short runway to Diavik’s planned closure,” Matthew Breen, chief operating officer at Diavik, told Rapaport.

While the diamond mine is slated to close in the first quarter of 2026, Rio previously indicated that some workers will remain at the mine site until 2029 to support the closure and reclamation process.

Elsewhere in NWT, De Beers’ Gahcho Kué mine, about 280 km away from Yellowknife, is expected to follow Diavik and close around 2030.

A report earlier this year shared by research firm Impact Economics estimates that these NWT diamond mine closures could result in 1,500 jobs being lost and about 1,100 residents leaving the territory.

Covid-19 Ravages De Beers Sales

De Beers’ sales and production nosedived in the second quarter as the coronavirus crushed diamond demand throughout the pipeline and forced shutdowns at several mines.

“Demand for rough diamonds was significantly impacted by a combination of Covid-19 restrictions [affecting] consumer demand and access to southern Africa, as well as severely limited midstream cutting-and-polishing capacity due to lockdowns, particularly in India,” De Beers said Thursday.

Rough sales slumped 96% year on year to $56 million after the company canceled its March-April sight — the first of the quarter — and allowed clients to defer all May and June purchases to later in the year. Sales volume plunged 97% to 300,000 carats, and prices fell as well, the miner noted.

Most sightholders were unable to attend the usual sales in Botswana due to travel restrictions. The pandemic also affected international shipments.

Meanwhile, the shutdown of India’s manufacturing sector reduced rough demand: Factories in Surat, the country’s cutting hub, closed in March for around two months, and ongoing virus outbreaks have disrupted the reopening process.

De Beers’ rough production fell 54% to 3.5 million carats during the quarter as the miner lowered its output to reflect the weak demand. Measures by southern African governments to contain the coronavirus also limited the company’s ability to operate, with Botswana and South Africa accounting for a large proportion of its mining activities, alongside Canada and Namibia.

Sales volume for the first half of 2020 slid 44% year on year to 9.2 million carats, with the average selling price down 21% at $119 per carat. The company sold a higher proportion of lower-value rough than a year ago, and average rough prices across the period slipped 8% year on year on a like-for-like basis.

Despite these setbacks, De Beers maintained its production forecast of 25 million to 27 million carats for the full year. However, it will review this outlook based on Covid-19 disruptions and “the timing and scale of the recovery in demand,” it said.

552 Carat Yellow Diamond Is The Largest Ever Found In Canada

Finding exceptionally large diamonds is rare. Finding extra large diamonds in fancy colors is even more rare. As such, the announcement by  Dominion Diamond Mines that it has unearthed  the largest known diamond ever found in North America is big news.

 Found in October at the Diavik Diamond Mine in  Calgary, Canada, the Canadamark yellow diamond weighs in at 552 carats and beats the previous record (held by the Diavik Foxfire diamond) of 187.7 carats that was also found at the same mine.

Dominion Diamond Mines ULC sources responsibly mined diamonds and owns 40 percent of Diavik.

 The Diavik Diamond Mine is just shy of 150 miles south of the Arctic Circle in the Northwest Territories of Canada, and has produced several important stones in the past. This newest discovery measures about 1-1/2 inches in diameter and more than 2 inches in height. The color and texture are unique geologically speaking, as such a large and rare yellow diamond doesn’t usually form in the region. According to Dominion Diamond Mines’ release, “Abrasion markings on the stone’s surface attest to the difficult journey it underwent during recovery, and the fact that it remains intact is remarkable.”

The Canadamark(TM) program by Dominion Diamond Mines ensures that all diamonds bearing its logo are rigorously tracked from mine to polished gem in order to offer final consumers  full transparency of the supply chain. Once the rough is cut, the diamonds will  be certified as Canadamark(TM).

In the case of the previously found Diavik Foxfire diamonds,  rather than sell it in the rough, the stone was  cut and polished  — yielding a 37.87-carat brilliant-cut pear shaped diamond and a 36.80 carat brilliant-cut pear shape. Both of these stones sold recently at a Christie’s auction for $1.3 million.  It is expected that Dominion Diamond Mines will take the same approach with the 552-carat Canadamark(TM) yellow diamond. The yield could be several larger sized diamonds that Foxfire, or could be similar sizes but more of them.  It is impossible to know, as a rough diamond must be carefully studied before being cut to determine the perfect size and shape of the finished, polished stones that will show off their most beautiful color and brilliance.

Certain other fancy yellow  diamonds have made history. In fact, among the world’s largest yellow diamonds is the 439.86 carat light-yellow diamond that was found by DeBeers in 1888 and later cut into a 234.65-carat cushion-cut stone.  The Tiffany Yellow Diamond is also one of  the largest ever discovered. It weighted 287.42 carats in the rough when it was found in 1878 in the Kimberly Mine in South Africa. It was eventually cut in to the 128.54-carat cushion known a the Tiffany Yellow Diamond.

According to  a release issued by Dominion Diamond Mines, Kyle Washington, Chairman, says  “This incredible discovery showcases what is truly spectacular about Canadamark diamonds. “The color and texture of the diamond are a unique example of the journey that natural diamonds take from their formation until we unearth them. Our Diavik Mine has produced some of the most beautiful diamonds in the world, and this one certainly tops the list.”
