Rio Tinto reported a $127m loss for 2024 from its Diavik diamond mine, in Canada, as weak market conditions led to “fixed cost inefficiencies”.
That compares with underlying earnings of $26m in 2023. Rio Tinto’s diamond sector generated $297m of revenue during the year, a 37 per cent drop on $444m the previous year.
The British-Australian multinational emailed over 1,300 employees last September, offering them voluntary separations to reduce operating costs as it prepares to close the mine next year.
In its Full Year Results 2024 the company noted the tragic loss of four Diavik workers and two air crew when a plane headed for the mine crashed last January.
Rio Tinto reported a 17 per cent drop in production, from 3.3m carats in 2023 to 3.4m carats in 2024.
The company acquired full ownership of the mine in November 2021 after it bought out a 40 per cent stake from Dominion Diamond Mines.
Rio Tinto launched on Wednesday its 2024 Beyond Rare tender, the second in its Art Series, showcasing 48 lots of extraordinarily rare stones from its diamonds business.
Titled Colour Awakened, this collection is headlined by seven “Old Masters”, notable historic diamonds from the Argyle diamond mine in Western Australia that operated from 1983 to 2020.
The Old Masters comprise seven round brilliant cut, pink and red diamonds, ranging in size from 0.60 carat to 2.63 carats. All unearthed from the mine over a decade ago in one case, as far back as 1987 each diamond has been carefully retrieved from private vaults and handpicked for inclusion in this year’s tender.
“No other mining company in the world has custody of such a kaleidoscope of coloured diamonds,” Sinead Kaufman, chief executive of Rio Tinto Minerals said in the statement.
In addition to the Old Masters, the Art Series 02 includes legacy inventory of pink, red and violet diamonds from the Argyle diamond mine, together with white and yellow diamonds from Rio Tinto’s Diavik diamond mine in Canada’s Northwest Territories.
“Four years on from the closure of the Argyle mine, our Beyond Rare Tender platform is a testimony to the enduring prestige of the Argyle Pink Diamonds brand, the quality of production from our Diavik mine, and the ongoing demand for highly collectible natural diamonds,” Kaufman said.
In total there are 76 diamonds, weighing 39.44 carats, comprising seven Old Masters, including one Fancy Red diamond; 32 single lots of pink and violet diamonds, including one Fancy Purplish Red diamond; and a rarified offering of nine carefully curated diamond sets, two of which include a 2.47 carat Fancy Intense Yellow diamond and a 4.04 carat D colour diamond, respectively, each from Diavik.
The 48 lots will be showcased in London, Australia, Singapore and Belgium, with bids closing on November 18.
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 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.
Pink and yellow diamonds from two iconic Rio Tinto mines – Argyle and Diavik – have been brought together to create a unique ring.
It’s called Diavik Midnight Sun and has been valued at $1.24m.
An 18.08 carat fancy intense yellow oval diamond from Diavik, in sub-Arctic Canada, contrasts with an intricate setting of rare Argyle pink diamonds, from the now-closed mine in in the remote East Kimberley region of Western Australia, weighing 4.09 carats in total.
The yellow diamond was cut from a 36.75-ct rough gem, described as one of the finest large yellow diamonds uncovered at Diavik.
Rio Tinto’s general manager of sales and marketing for its diamonds business, Patrick Coppens said “This combination of a rare yellow Diavik diamond and Argyle Pink Diamonds, the rarest diamonds in the world, is a special moment in the history of Rio Tinto’s unique place in the natural fancy coloured diamond industry.
He paid tribute to luxury jeweler Musson for creating the ring. The Diavik Midnight Sun takes its inspiration from the exquisite natural phenomenon that occurs when the sun is seen at midnight in the Arctic, exhibiting beautiful golden and pink hues.
Diamonds from Rio Tinto’s Argyle Pink Diamond Tender.
Rio Tinto has debuted a new strategy that will enable it to “protect the provenance” of its Argyle pink diamonds, including a certification service and a concierge trading platform.
“This is the start of a new chapter for Argyle pink diamonds, to ensure they maintain their value and investment potential as a finite, unrepeatable natural resource and achieve the status of outstanding heritage diamonds,” Rio Tinto Minerals CEO Sinead Kaufman said last week.
The venture will also play host to a new Beyond Rare tender platform for special sales events, as well as several strategic collections and collaborations involving existing inventory and the secondary market.
One such venture, the Icon Partner program, will give jewelers licensing rights to use the Argyle Pink Diamonds brand for jewelry they create with any remaining inventory they previously purchased from the Argyle mine. The first two retailers Rio Tinto has authorized are John Calleija, the owner of Australian luxury-jewelry house Calleija, and Singapore-based Glajz THG, owned by John Glajz.
“The secondary market for Argyle pink diamonds comprises almost 40 years of rare, polished pink diamonds, together with heirloom pieces of jewelry, collectibles and objects,” the miner noted. “This market requires careful management to preserve the precious provenance of Argyle pink diamonds and continue the legacy of careful custody that underscores its rarity.
