Production will cease at the De Beers Victor mine in Canada in 2019, the company announced Wednesday.
The Diamond Mine in Ontario started production in July 2008 will continue to operate until the open pit is exhausted. This is in line with the company’s original study of mine and the plan for the project.
The mine has yielded 7 million carats of rough exceeding the forecast of 6 million carats predicted for its life of mine.
De Beers discovered the Victor kimberlite cluster in 1987 the first economically viable mine in Canada.
Due to resources dwindling Beers’ joint ventures will close four diamond mines by 2022.
Namdeb is a DeBeers project with the government of Namibia, Will close the Elizabeth Bay mine at the end of 2018 followed by the Daberas deposit at the end of 2019 and Sendelingsdrif in 2020. The main asset Southern Coastal will close in 2022.
Production saw a shift to offshore assets this past year. For the first nine months of 2017, Debmarine’s production surged 22% to 1.1 million carats.
Subdued world economic growth will make the next few years challenging, mainly due to negative impacts forecast in exchange rates and other indices.
De Beers’ October sight closed with a value of $370 million as rough-diamond buying slowed due to holidays and sightholders reported a sluggish dealer market.
Proceeds from the miner’s eighth sales cycle fell 27% from $507 million in the previous sight in August, and dropped 25% compared with the equivalent period a year ago, according to Rapaport records. Rough prices were largely unchanged from the previous sight, sightholders noted, with many dealers on the secondary market struggling to make a profit on the goods or even cover costs.
De Beers offered fewer rough diamonds for sale during the month as last week’s sight occurred during a period when polishing factories in India and Israel were closed for religious holidays, the company’s CEO Bruce Cleaver explained Tuesday.
“Sales were in line with expectations, at what is a seasonally slower time for rough-diamond demand,” Cleaver added.
The Indian cutting industry is preparing to close for Diwali, which occurs this Thursday. Buyers brought rough purchases forward to the July sales cycle because of the relatively early date of the festival this year, De Beers noted at previous sights. The last two sights have both been significantly smaller than a year ago as a result.
Sightholders were optimistic about the end-of-year holiday season, even as De Beers’ rough sales have declined 7% to $4.38 billion for the year to date, Rapaport records show. Russian miner Alrosa echoed this positive outlook, also noting that the timing of Diwali had weakened sales in September.
“We expect the traditional revival of the market situation in the fourth quarter, as the industry starts to prepare for the winter holiday season,” Alrosa vice president Yury Okoyomov said last week.

Geologists have discovered what they refer to as young diamonds, after analyzing a number of rough diamonds.
It now appears the creation of rough diamonds, may have occurred later in the Earth’s history than was previously thought. Diamond requires extreme temperatures and pressures to form. Geologists though these conditions only existed in the early formation of Earth.
Small impurities in the diamonds could indicate the conditions in which they are formed. So 26 diamonds donated by the De Beers Group where analyzed by a research team in Amsterdam.
Sm-Nd isotope techniques are used by researchers to analyzed the sampled garnet inclusions, Which are a common mineral found in Earth’s mantle and sometimes within the diamonds.
The scientists discovered two sets of diamonds, one of Archaean age 2.95 billion years old thought to be the original source of the diamonds. And then surprisingly the other of Proterozoic age 1.15 billion years old.
The world’s second largest 1,109 carat rough diamond discovered two years ago, has prompted the Botswana government to amend the law giving it first option to buy unusually large diamonds.
