Miners seeking new capital have always had a variety of options: they could issue new shares, take out a loan, enter into joint-venture agreements, or divest non-core assets.
However, in the last decade, a new option has emerged called “precious metals streaming” – in which streaming companies essentially offer capital up front to mining companies in exchange for metal later. If properly executed, the end result is a win for both parties that can ultimately provide value to investors.
Precious Metals Streaming
Today’s infographic from Silver Wheaton explains the precious metals streaming model, and the arbitrage opportunity that creates value for both the streamer and the miner seeking to acquire capital:
The aforementioned arbitrage opportunity in precious metals streaming is key.
For a traditional base metal miner, the majority of forecasted mine revenue may come from a metal like copper or nickel. However, along with those “target” metals, smaller amounts of gold and silver may be produced from the deposit as well.
Investors would still value those by-product precious metals in a base metal miner’s portfolio, but the metals may be typically valued at an even higher multiple in a precious metal streamer’s portfolio. This allows the base metal miner to transfer these future “streams” to the streamer in exchange for up-front capital, which can be a win-win scenario for both parties.
In other words, miners use streaming to acquire non-dilutive financing, and to extract value from non-core assets. This allows them to deploy capital on purposes more central to their strategy. Major miners such as Teck, Barrick Gold, Vale, and Glencore all sold streams in 2015.
Meanwhile, streaming companies have been very successful since this model was first pioneered 12 years ago. They are getting gold and silver at a discount, and this has created significant amounts of value for investors over the last decade. Today, there are many valuable streaming companies out there, including the major ones such as Silver Wheaton, Royal Gold, and Franco-Nevada.
Ranked: The World’s Top Diamond Mining Countries, by Carats and Value
Who are the leaders in rough diamond production and how much is their diamond output worth?
Ranked: World Diamond Mining By Country, Carat, and Value
Only 22 countries in the world engage in rough diamond production—also known as uncut, raw or natural diamonds—mining for them from deposits within their territories.
This chart, by Sam Parker illustrates the leaders in rough diamond production by weight and value. It uses data from Kimberly Process (an international certification organization) along with estimates by Dr. Ashok Damarupurshad, a precious metals and diamond specialist in South Africa.
Rough Diamond Production, By Weight
Russia takes the top spot as the world’s largest rough diamond producer, mining close to 42 million carats in 2022, well ahead of its peers.
Russia’s large lead over second-place Botswana (24.8 million carats) and third-ranked Canada (16.2 million carats) indicates that the country’s diamond production is circumventing sanctions due to the difficulties in tracing a diamond’s origin.
Here’s a quick breakdown of rough diamond production in the world.
|5||🇿🇦 South Africa||9,660,233|
|10||🇸🇱 Sierra Leone||688,970|
|18||🇨🇮 Cote D'Ivoire||3,904|
|19||🇨🇬 Republic of Congo||3,534|
Note: South Africa’s figures are estimated.
As with most other resources, (oil, gold, uranium), rough diamond production is distributed unequally. The top 10 rough diamond producing countries by weight account for 99.2% of all rough diamonds mined in 2022.
Diamond Mining, by Country
However, higher carat mined doesn’t necessarily mean better value for the diamond. Other factors like the cut, color, and clarity also influence a diamond’s value.
Here’s a quick breakdown of diamond production by value (USD) in 2022.
|5||🇿🇦 South Africa||$1,538M|
|9||🇸🇱 Sierra Leone||$143M|
|19||🇨🇬 Republic of Congo||$0.20M|
|20||🇨🇮 Cote D'Ivoire||$0.16M|
Note: South Africa’s figures are estimated. Furthermore, numbers have been rounded and may not sum to the total.
Thus, even though Botswana only produced 59% of Russia’s diamond weight in 2022, it had a trade value of nearly $5 billion, approximately 1.5 times higher than Russia’s for the same year.
Another example is Angola, which is ranked 6th in diamond production, but 3rd in diamond value.
Both countries (as well as South Africa, Canada, and Namibia) produce gem-quality rough diamonds versus countries like Russia and the DRC whose diamonds are produced mainly for industrial use.
Which Regions Produce the Most Diamonds in 2022?
Unsurprisingly, Africa is the largest rough diamond producing region, accounting for 51% of output by weight, and 66% by value.

However diamond mining in Africa is a relatively recent phenomenon, fewer than 200 years old. Diamonds had been discovered—and prized—as far back as 2,000 years ago in India, later on spreading west to Egyptian pharaohs and the Roman Empire.
By the start of the 20th century, diamond production on a large scale took off: first in South Africa, and decades later in other African countries. In fact between 1889–1959, Africa produced 98% of the world’s diamonds.
And in the latter half of the 20th century, the term blood diamond evolved from diamonds mined in African conflict zones used to finance insurgency or crime.
