Rio Tinto’s Beyond Rare diamond tender delivers strong results

Diversified mining company Rio Tinto’s second Beyond Rare tender has achieved a strong result, underscoring the rarity and unique provenance of the diamonds on offer.

The auction, which featured some of the world’s most coveted natural fancy coloured diamonds, also showcased the continuing global demand for these rare treasures.

The collection, which comprises 76 diamonds across 48 lots, included an exceptional mix of pink, red, and violet diamonds from the now-closed Argyle diamond mine in Australia, as well as white and yellow diamonds from Rio Tinto’s Diavik mine in Canada.

For the first time, the tender also included seven “Old Masters”, notable historic diamonds from the Argyle mine, further elevating the event’s appeal to collectors.

The tender saw successful bids from 12 bidders spanning Australia, Europe, Japan, Hong Kong, the Middle East, Singapore, and North America.

“The continued strong global interest in highly collectible natural coloured diamonds and the resulting value creation, reflects their stature as works of art to be treasured for future generations,” commented Rio Tinto Minerals CEO Sinead Kaufman.

One standout lot, Lot 40, which featured a 4.04-ct pear-shaped pure white diamond from the Diavik mine, alongside two rare pear-shaped violet diamonds from the Argyle mine, was entrusted to Danish luxury jeweller Hartmanns. The company will work with Glajz, an Argyle Pink Diamonds Icon Partner, to create a one-of-a-kind heirloom jewellery piece from these diamonds.

“I am honoured to be creating a jewelled treasure that reflects each magnificent birthplace of these three esteemed diamonds – Argyle in the remote East Kimberley region of Western Australia and Diavik, just below the Arctic Circle on the frozen edge of the earth in Canada’s Northwest Territories,” said Hartmanns owner Ulrik Hartmann.

Rio Tinto’s Argyle diamond mine, which ceased production in November 2020, was the source of nearly entirely the world’s total supply of rare pink and red diamonds. With 37 years of production, Rio Tinto continues to manage the Argyle Pink Diamonds brand, facilitating sales of remaining inventory and collaborating with prominent jewellers globally.

In addition to owning the Argyle Pink Diamonds™brand, Rio Tinto is the majority owner and operator of the Diavik mine in Canada. The company also continues to explore new opportunities in the diamond sector, with a recent joint venture agreement with Endiama, the national diamond mining company of Angola, to explore the Chiri kimberlite in Angola’s Lunda Sul province.

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.

Rio Tinto’s Diavik Mine Slides into the Red

Rio Tinto today reported a slump in half-yearly sales and production as its Diavik diamond mine in Canada slid into the red.

The Australian mining giant reported a 15 per cent increase in overall profits across all divisions to $5.8bn for the six months to 30 June, but its diamond operation suffered a $65m loss. During the same six months of 2023 it made a $44m profit.

The Half Year Results made passing mention of “lower volumes” of diamonds, but chief executive Jakob Stausholm offered no explanation.

Revenue from diamond sales was down 40 per cent during H1, from $250m to $149m. Production fell 25 per cent, from 1.924m carats to 1.441m carats.

Earlier this month the company said production at Diavik had fallen by by 28 per cent during Q2, impacted by the transition to underground operations and the plane crash in January that killed four of its workers and two crew members. A chartered Jetstream twin turboprop airliner crashed shortly after take-off from Fort Smith Airport.

Rio Tinto Workers Killed en Route to Diavik Diamond Mine

A number of remote employees at Rio Tinto’s Diavik diamond mine in Canada died Tuesday after the small plane carrying them to the site crashed.

“We have been informed by authorities that a plane on its way to our Diavik mine, carrying a number of our people, crashed…resulting in fatalities,” said Rio Tinto CEO Jakob Stausholm.

The company has not disclosed how many died on board the aircraft, which seats 19 people. The plane crashed near Fort Smith in the Northwest Territories shortly after takeoff. Rio Tinto employs many remote workers, who operate in shifts at the mine. Because of its isolated location, the miner transports workers by aircraft to and from the deposit.

“I would like to extend our deepest sympathy to the families, friends and loved ones of those who have been affected by this tragedy,” Stausholm said. “As a company, we are absolutely devastated by this news and [are] offering our full support to our people and the community, who are grieving today. We are working closely with authorities and will help in any way we can with their efforts to find out exactly what happened.”

Northwest Territories Premier R.J. Simpson also mourned the loss.

“It is with a heavy heart that I express my deepest condolences to the families, friends, and loved ones of those who were aboard the Northwestern Air flight that crashed outside of Fort Smith today,” he noted. “The impact of this incident is felt across the territory…. As we seek to understand the circumstances of this tragedy, I’d also like to extend a heartfelt thank you to the first responders and rescue teams who continue to work tirelessly at the crash site.”

It is unclear whether the crash will impact diamond production or sales at Diavik.

Rio Tinto Output Dwindles as Mine Depletes

Rio Tinto’s diamond production fell in 2023 following the closure of portions of its Diavik mine in Canada earlier in the year.

Total production dropped 28% to 3.3 million carats for the full year, the company said Tuesday. Rio Tinto completed mining at Diavik’s A418 underground area and at its A21 open-pit kimberlite pipes, it explained. Improvements in the volume of ore produced at the A154N underground partially offset the loss in output from those portions.

In the fourth quarter, output slipped 50% year on year to 659,000 carats, and was down 13% from the previous quarter.

Diavik is Rio Tinto’s sole diamond mine following the closure of Australia’s Argyle deposit in November 2020. The miner’s share of Diavik increased from 60% to 100% in November 2021, when it assumed control of the asset following the inability of its joint-venture partner, Dominion Diamond Mines, to pay its share of upkeep. In November, Rio Tinto also sold its 75% share of the Fort à la Corne diamond exploration project in Saskatchewan to joint-venture partner Star Diamond Corporation, in an effort to focus on metals and minerals.

Rio Tinto will spend $40 million to move into underground mining at the A21 portion of Diavik, which it believes could add more than 2 million carats of rough production, it reported in February 2023. That expansion is due to keep the mine in operation until the first quarter of 2026.

Meanwhile, the company did not provide rough-production guidance for 2024.

Rio Tinto Delighted with Argyle and Diavik Tender

Rio Tinto said it was delighted with the results of its first Beyond Rare Tender of polished pink and red diamonds from Argyle, in Australia, and yellow stones from Diavik, Canada, though it declined to reveal any prices.

Sinead Kaufman, chief executive of Rio Tinto Minerals, said only that the results reflected the global demand for highly collectible natural colored diamonds.

The first in a series of sales featured a collection of 87 diamonds, weighing 29.96 carats in total. Successful bidders came from Australia, Europe, Japan, Hong Kong, Singapore, US and Israel.

Among the lots were seven Masterpiece sets of Argyle dink diamonds and yellow Diavik diamonds, 11 matched pairs of colored diamonds and 30 single diamonds, including one remarkable fancy red Argyle diamonds.

The iconic Argyle mine closed in November 2020 after 37 years. It produced 90 per cent of the world’s pink, red, blue and violet diamonds.

Rio Tinto to spend $40m on Diavik diamond mine expansion

 Rio Tinto to spend $40m on Diavik diamond mine expansion

Rio Tinto is going ahead with a $40 million expansion of its iconic Diavik diamond mine in the Northwest Territories of Canada, which will extend the operation’s life to at least early 2026.

The approved first phase of the project will expand diamond extraction underground, below the existing A21 open pit. Mining of that area, opened in 2018, recently concluded.

A second phase an additional cost will be put forward for approval in 2024, Rio said.

Phase one below A21 is slated to produce an extra 1.4 million carats, with phase two adding another 800,000 carats.

“This is good news for our employees, partners, suppliers and local communities in the Northwest Territories,” Sinead Kaufman, Rio Tinto Minerals’ chief executive, said in a statement.

Rio Tinto became in 2021 the sole owner of the operation, after buying the 40% share held until then by Dominion Diamond Mines.

The company has operated Diavik since production began in 2003. Located approximately 300 km north-east of Yellowknife, the mine employs over 1,100, of which 17% are Northern Indigenous people.

Diavik is Canada’s largest diamond mine in terms of production with between 6 and 7 million carats of rough diamonds produced each year. Since mining began in 2003 Diavik has produced over 100 million carats of diamonds.

The Northwest Territories’ two other diamond mines – Ekati, operated by Arctic Canadian Diamond and De Beers-Mountain Province’s Gahcho Kué – are expected to close in 2024 and 2028, respectively.

Diavik is about 30 km southeast of Ekati, and Gahcho Kué is 125 km southeast of Diavik.
