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.
