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.

Rio Tinto Production to Slump as Diavik Dries Up

Rio Tinto has forecast a sharp drop in rough-diamond output for next year as the Diavik mine edges closer to depletion.

The company expects to produce between 3 million and 3.8 million carats from the Canadian deposit in 2023, it reported at an investor seminar Wednesday. That compares with a plan of 4.5 million to 5 million carats for this year.

The decrease is a result of the exhaustion of rough supply from some of Diavik’s major mining areas, a Rio Tinto spokesperson told Rapaport News. The mine, which employs 1,100 workers, is set to close in 2025.

“We’ve completed mining at the A21 pipe, which was the latest pipe opened in 2018,” the spokesperson explained. “We’re finishing surface mining, and also one of the underground parts of the mine is done, so this is part of the plan changes. There are four areas we are mining at the moment, and next year there will be two.”

Diavik, of which Rio Tinto is the sole owner, is currently the miner’s only operational diamond site. The company’s Argyle deposit, known for its fancy-pink diamonds, closed in November 2020. Meanwhile, an exploration partnership with Star Diamond is on hold as Rio Tinto considers an exit from the project.

Rio Tinto’s Unique $1.24m Midnight Sun Diamond Ring

Midnight Sun Diamond Ring
Midnight Sun Diamond Ring

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.

Rio Tinto Buys Remaining Share of Diavik Diamond Mine

Rio Tinto office in Montreal, QC, Canada

Rio Tinto, the world’s second-largest miner, just became the sole owner of the Diavik diamond mine in Canada’s Northwest Territories on Thursday. Despite saying in the past the Company was not interested in taking full control of the aging arctic mine, Rio Tinto ended up buying the 40% share held by Dominion Diamond Mines for a total stake of 100%.

Part of the transaction includes Rio Tinto releasing Dominion and its lenders from any outstanding liabilities or obligations involving funding the operation or the closure of the joint venture. On the other end, Rio Tinto will receive all remaining Diavik assets held by Dominion including a security cash collateral for the potential future closure for the mine and unsold production.

Why the Buyout Now?
Dominion, which used to be the fourth-largest diamond producer, suffered some financial troubles which played out in court over several months last year. These troubles ultimately led Dominion to sell its other Canadian mine, Ekati in December 2020. In 2017, The Washington Companies ended up buying the Company for $1.2 billion.

This deal follows a 19 month long process beginning in April 2020 by Dominion Diamond Mines filing for insolvency protection under the Canadian Companies’ Creditors Arrangement Act.

Diavik has been in production since 2003 and is eventually facing closures in 2025 which will cost hundreds of millions of dollars to fully clean up. Diavik is Canada’s largest diamond mine, and yielded 6.2 million carats of rough diamonds in 2020.

Rio Tinto Minerals boss Sinead Kaufman said in a statement, “Diavik will now move forward with certainty to continue supplying customers with high quality, responsibly sourced Canadian diamonds.”

Worries and concerns began to surround the diamond market due to production coming to a

halt during the global COVID-19 pandemic, with some people worried the market would never recover. However, Alrosa, the world’s top diamond miner by output, claims the market has fully recovered from the effects of the global pandemic, and sales of jewelry and rough diamonds are up 23% this year compared to 2020.

Kunming partners with Rio Tinto for Argyle diamonds

Argyle tender pink diamonds

The world’s second-largest miner, Rio Tinto (ASX, LON, NYSE: RIO), announced that Hong Kong-based coloured diamond specialist Kunming Diamonds is now one of the company’s 13 authorized partners for Argyle pink diamonds. 

In a press release, Rio said this means Kunming will be entrusted with the care and custody of the gems. 

Established in 1987, Kunming is a global, multi-generational company that has built its business into one of Asia’s leading coloured diamond specialists. In 2019, the company was successful in acquiring the entire Argyle Pink Everlasting Collection, a one-off exclusive selection of certified Argyle pink and red diamonds. 

“This is a wonderful honour and showcases our commitment to bringing the world’s rarest diamonds to our global partners and client base,” Harsh Maheshwari, director of Kunming, said in the brief.

Firestone Diamonds’ Liqhobong mine back at full tilt as power returns

Lucapa Diamond Mine

Shares in Africa focused Firestone Diamonds went ballistic on Wednesday after it announced that stable power had returned to its Liqhobong mine in Lesotho, with the plant processing at full capacity.

Firestone had warned in October that the mine was struggling due to insufficient power supply due to a two-month maintenance shutdown at its only power supplier — Lesotho Highlands Water Project.

As a result, processing operations were halted from the beginning of the month to Oct. 26, when diesel generators were commissioned. The plant then operated at between 80% and 90% capacity throughout November.

While the LHWP resumed operations on Dec. 1, the company said it had to book $1.1 million in additional costs from the use of the generators, adding that it had also filed an insurance claim over loss of profit.

Firestone’s stock was up 128% on Wednesday mid-day in London at 0.97 pence a share, leaving the company with a market capitalization of £6.18 million. The stock price, however, is far from the £3.88 the company’s shares were trading at a year ago.

Diamond miners are struggling across the board, especially those producing cheaper and smaller stones, where there is an over-supply.

Increasing demand for synthetic diamonds has also weighed on prices. Man-made diamonds require less investment than mining natural stones and can offer more attractive margins.

Buyers, those that polish and cut diamonds for retailers, have been hit this year by lower prices and tighter credit, prompting them to delay purchases.

De Beers, the world’s No.1 diamond miner by value, has responded by axing production — with a target of 31 million carats this year compared with 35.3 million in 2018. It has also given buyers more room to maneuver, by allowing them to refuse half the stones in many of the diamond parcels.

The Anglo American unit is also spending more on marketing. At the latest sale, the company increased the amount of stones buyers were allowed to reject in each lot purchased from 10% to 20%, according to people familiar with the auction.

Firestone’s chief executive, Paul Bosma, has said he’d expect prices for smaller diamonds to increase towards the end of 2020, in part due to the closure of Rio Tinto’s Argyle mine in Australia.

Diamond miners dented by liquidity crisis among India’s polishers

liquidity crisis among India’s polishers

Diamond miners are feeling the pressure after a funding crunch in the world’s polishing hub dented sales of rough gemstones.

Since celebrity jeweller Nirav Modi fled India in 2018 accused of having defrauded a state bank of nearly $2bn, banks have sharply cut back lending to diamantaires, who cut, polish and trade the world’s diamonds.

“Bankers have blacklisted the jewellers industry,” said Shantibhai Patel, president of the Indian Bullion and Jewellers Association in Gujarat, the country’s diamond-cutting centre.

The squeeze has forced diamantaires to buy less from diamond producers such as De Beers, Rio Tinto and Gem Diamonds — which have seen sales and margins suffer as a result.

De Beers is on course to report its worst annual sales in at least four years. In response, the world’s largest producer reduced prices for its rough diamonds by 5 per cent last month at its November sale, the biggest discount in years, Bloomberg reported. De Beers declined to comment on its pricing.

Across the sector, rough diamond prices have fallen 15 per cent since last November, according to Polished Prices. Industry experts say a further 10-15 per cent drop would push some smaller producers to file for bankruptcy.

“It’s a liquidity crisis that’s affecting the middle of the pipeline,” said Edward Sterck, an analyst at BMO Capital Markets. “Diamond manufacturers can’t afford to pay rough diamond prices . . . It’s a function of necessity that prices have come down.”

Diamantaires — 90 per cent of which are based in India — buy rough diamonds from producers such as De Beers that they then cut with lasers and polish for use in jewellery.

The flight of Mr Modi, whose clients included actress Kate Winslet, prompted banks to tighten up lending terms for manufacturers. Bank credit to the diamond industry, of which Indian companies receive about four-fifths, fell 20 per cent to $8bn this year, according to WWW International Diamond Consultants.

As a result, diamond cutters are working through existing stocks rather than buying on the global market. According to India’s Gem and Jewellery Export Promotion Council, imports of rough diamonds into the country fell 22 per cent year over year to $7.3bn between April and October.

This has struck diamond mining companies hard. Stuart Brown, chief executive at Toronto-based Mountain Province Diamonds, said the rough stone market was “challenging” in its third-quarter results.

Mid-sized producers including Canada’s Lucara Diamond and the UK’s Petra Diamonds all reported lower prices for their diamonds in the latest quarter. Lucara reported a selling price of $390 a carat, a 13 per cent drop from last year and a steep fall from 2014, when gems sold for $644 a carat. Dire market conditions drove Quebec-based Stornoway Diamond into bankruptcy in September.

The diamond industry differs from other commodities given the large influence of the two largest producers on pricing, and the fact that diamonds vary in size, quality and colour. De Beers is a “price setter” that offers uncut stones to traders for fixed prices and quantities at sales, known as “sights”.

Production cuts and concessions, including discounts and flexibility to return stones, have provided some relief to De Beers and its customers. Sales rose last month but were still below $400m — the lowest in a November sight on record.

Mr Patel welcomed the Anglo American-owned company’s price cut, but expected little uplift in the foreseeable future. “There’s no work,” he said. “For one year, one and a half years, we’re not expecting any bullish trends.”

But Colin Shah, managing director of manufacturer Kama Schachter, is hopeful that the worst was over for diamantaires. He said that manufacturers were adjusting to the tougher norms in place after the Modi scandal, which could get liquidity flowing again.

“There’s much more [scrutiny] than there used to be,” he said, referring to banks’ lending practices. “Inventories have come down, everyone has made their business models leaner . . . I think the second half of 2020 will be better.”

Industry executives point to tightening supply over the next few years that will help restore diamonds’ key feature: rarity. Rio Tinto’s Argyle mine, which outputs 90 per cent of the world’s valuable pink diamonds, is set to close next year.

Meanwhile, retail demand for diamonds has been robust, particularly in the US where spending on diamond jewellery grew 4.5 per cent to $36bn last year. French luxury group LVMH’s $16.6bn acquisition of Tiffany, agreed last week, was seen by analysts as a vote of confidence in long-term consumer demand for diamond jewellery.

But other industry figures say more drastic action by diamond mining companies is needed to help bedraggled manufacturers. Martin Rapaport, founder of the world’s largest diamond trading platform, said the price cut was insufficient. “It’s not enough to recapitalise the industry,” he said.

“They need to drop prices as much as 50 per cent to return liquidity to the market. It’s too little too late.”

Rio Tinto Output Falls Amid Lower Grades

rio tinto

Lower mining grades and reduced ore availability contributed to a drop in Rio Tinto’s third-quarter diamond production, the company reported Wednesday.

Output at its wholly owned Argyle mine in Australia fell 7% year on year, yielding 3.6 million carats in the three-month period ending September 30. Production was hampered by lower grades, despite stronger mining and processing rates, Rio Tinto said.

Rio Tinto’s share of production at the Diavik mine in Canada also shrank 7% to 994,000 carats for the same period due to lower ore availability both underground and at the A21 extension pipe it opened in August last year. The company owns 60% of the deposit, with Dominion Diamond Mines holding the remainder.

Rio Tinto’s total diamond production, including its share of Diavik goods, dropped 7% to 4.5 million carats.

For the first nine months of the year, the miner produced 12.8 million carats, compared to 14.1 million in the same period of 2018. Its 2019 forecast remains unchanged at 15 million to 17 million carats, down from 18.4 million carats last year.
