Canadian diamond discoveries could close pending supply gap

On November 1st, De Beers said that it will be closing its nearly depleted Victor diamond mine in northern Ontario in early 2019. Victor is the first in a line of legacy diamond mines world-wide that will be closing over the next 5-years.

Most notably, Rio Tinto’s illustrious Argyle mine in Australia is expected to shut operations in 2021. At peak production, in the mid-90’s, Argyle produced over 40M carats annually. To put that into perspective, total 2017 global diamond output is estimated at less than 150M carats.

De Beers Voorspoed mine in Botswana is on pace to reach end-of-life by the end of the decade, and a slew of the company’s alluvial mines in Namibia are planned to be phased out by 2022.

With global diamond demand forecast to grow at approximately 3.5% annually over the next five years, driven by middle class consumers in Mainland China and India, the industry’s fastest growing large markets, a supply gap down the line seems inevitable if forecasts hold.

Globally there only two new diamond projects in the works with annual production potential of in excess of 1M carats, one in Angola, the other in Russia. Further, new diamond project exploration has been limited by challenges in the upstream diamond industry’s primary jurisdictions.

Greenfields diamond exploration in South Africa is at multi-decade lows due to delays in granting of prospecting licenses and perceived risks of a new Mining Charter, and this year there was a production disruption at the Williamson diamond mine in Tanzania related to government changes in mining legislation.

In Botswana, home to De Beers’ primary asset base, the country has been heavily explored and most major diamond discoveries are assumed to already have been made. In Russia, most major diamond production in is controlled by government entities.

This makes Canada, already the third largest diamond producing nation in the world by value (see chart above), arguably the most prospective diamond exploration jurisdiction in the world. In May of this year, Canada’s leading diamond producer, Dominion Diamond (private), pledged to spend C$50M on exploration over next 5 years, the company’s first major greenfields exploration since 2007.
