The Story of the Golden Triangle in British Columbia
The Golden Triangle
In a hidden corner of Northwestern Canada lies some of the world’s most significant mineral potential.
Billions of dollars of undiscovered gold, silver, and copper still sit within an unexplored area that was once remote. However, only now can these world-class deposits be finally tapped.
Skeena Resources has generously helped us to put together the story of the famed Golden Triangle.
The History of the Golden Triangle
Even before Canada was officially a country, the area now known as the Golden Triangle was a hub for prospectors looking to strike it rich.
In 1861, Alexander “Buck” Choquette struck gold at the confluence of the Stikine and Anuk Rivers, kickstarting the Stikine Gold Rush. More than 800 prospectors left Victoria to go to the Stikine in search of gold.
A few short years later, an even more significant rush would occur just to the north in the Cassiar region – it’s where British Columbia’s biggest ever gold nugget, weighing in at 73 ounces, would be found. The Atlin Gold Rush, an offshoot of the world-famous Klondike Gold Rush, would also occur just north of the Triangle.
The First Discoveries
The companies that first worked in the Golden Triangle balanced its richness against the costs of its remote location.
1. Premier Gold Mine
The first big discovery in the Golden Triangle was at the Premier Gold Mine, which started operations in 1918.
The company that first owned it, Premier Gold Mining Company, returned as much as 200% on the stock market between 1921 and 1923. At the time the Christian Science Monitor called it “One of the greatest silver and gold mines in the world.”
2. Snip Mine
Discovered in 1964 by Cominco, the deposit stayed dormant until 1986, when it was drilled in a joint venture with Delaware Resources. Murray Pezim’s Prime Resources bought out Delaware after the stock ran from a dollar to $28 a share.
The high-grade Snip mine produced approximately one million ounces of gold from 1991 until 1999 at an average gold grade of 27.5 g/t.
3. Eskay Creek
In 1988, after a 109 drill holes, tiny exploration companies Stikine Resources and Calpine Resources finally hit the hole they needed at Eskay Creek: 27.2 g/t Au and 30.2 g/t Ag over 208m.
Eskay would go on to become Canada’s highest-grade gold mine and the world’s fifth largest silver producer, with production well in excess of 3 million ounces of gold and 160 million ounces of silver.
Grades:
Gold: 49 g/t
Silver: 2,406 g/t
Lead: 3.2%
Zinc: 5.2%
By the time it was all said and done, the stock price of Stikine Resources would go from $1 to $67, after it was bought by International Corona.
Why did these three rich mines shut down?
Despite the gold in the Triangle being extremely high grade, lower gold prices in the late 90s made the economics challenging. Meanwhile, the lack of infrastructure in this remote area of Canada meant that power, labor, and logistics costs were sky high.
Both of these things have changed today, and activity at the Golden Triangle is now fast and furious.
Gaining Access to the Triangle
The Golden Triangle is a hot area for exploration again. This is for three main reasons: higher gold prices, new infrastructure, and modern discoveries.
Higher gold prices
Average gold price (1999): $279 (Adjusted for inflation: $398)
Average gold price (2016): $1202
Gold prices are more than 3x as high today, even after adjusting for inflation. Combined with the Golden Triangle’s high grades, this becomes even more attractive.
New Infrastructure:
Today, road access to the area is easier than ever, and a new transmission line will dramatically reduce the cost of power for companies operating in the Triangle.
Recent improvements:
- Completion of a $700 million high-voltage transmission line to the Golden Triangle. The Northwest Transmission Line goes 335km from Terrace to Bob Quinn Lake, and north to the Red Chris mine
- Paving of the Stewart-Cassiar highway north from Smithers (Hwy 37)
- Opening of ocean port facilities for export of concentrate in Stewart
- Completion of a three dam, 277 MW hydroelectric facility located 70km northwest of Stewart
With new infrastructure in tow, the Golden Triangle is now open for business.
Modern Discoveries
The next gold rush at the Golden Triangle has already started.
Just some of the new discoveries in the area include Seabridge’s KSM project, Pretium’s Valley of the Kings deposit, and Imperial Metal’s Red Chris mine.
Yet, despite this track record of new discoveries and mines being built in the area, a British Columbia government report estimates that only 0.0006% of the Golden Triangle has been mined to date.

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.
Rank | Country | Rough Diamond Production (Carats) |
---|---|---|
1 | 🇷🇺 Russia | 41,923,910 |
2 | 🇧🇼 Botswana | 24,752,967 |
3 | 🇨🇦 Canada | 16,249,218 |
4 | 🇨🇩 DRC | 9,908,998 |
5 | 🇿🇦 South Africa | 9,660,233 |
6 | 🇦🇴 Angola | 8,763,309 |
7 | 🇿🇼 Zimbabwe | 4,461,450 |
8 | 🇳🇦 Namibia | 2,054,227 |
9 | 🇱🇸 Lesotho | 727,737 |
10 | 🇸🇱 Sierra Leone | 688,970 |
11 | 🇹🇿 Tanzania | 375,533 |
12 | 🇧🇷 Brazil | 158,420 |
13 | 🇬🇳 Guinea | 128,771 |
14 | 🇨🇫 Central African Republic | 118,044 |
15 | 🇬🇾 Guyana | 83,382 |
16 | 🇬🇭 Ghana | 82,500 |
17 | 🇱🇷 Liberia | 52,165 |
18 | 🇨🇮 Cote D'Ivoire | 3,904 |
19 | 🇨🇬 Republic of Congo | 3,534 |
20 | 🇨🇲 Cameroon | 2,431 |
21 | 🇻🇪 Venezuela | 1,665 |
22 | 🇲🇱 Mali | 92 |
Total | 120,201,460 |
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.
Rank | Country | Rough Diamond Value (USD) |
---|---|---|
1 | 🇧🇼 Botswana | $4,975M |
2 | 🇷🇺 Russia | $3,553M |
3 | 🇦🇴 Angola | $1,965M |
4 | 🇨🇦 Canada | $1,877M |
5 | 🇿🇦 South Africa | $1,538M |
6 | 🇳🇦 Namibia | $1,234M |
7 | 🇿🇼 Zimbabwe | $424M |
8 | 🇱🇸 Lesotho | $314M |
9 | 🇸🇱 Sierra Leone | $143M |
10 | 🇹🇿 Tanzania | $110M |
11 | 🇨🇩 DRC | $65M |
12 | 🇧🇷 Brazil | $30M |
13 | 🇱🇷 Liberia | $18M |
14 | 🇨🇫 Central African Republic | $15M |
15 | 🇬🇾 Guyana | $14M |
16 | 🇬🇳 Guinea | $6M |
17 | 🇬🇭 Ghana | $3M |
18 | 🇨🇲 Cameroon | $0.25M |
19 | 🇨🇬 Republic of Congo | $0.20M |
20 | 🇨🇮 Cote D'Ivoire | $0.16M |
21 | 🇻🇪 Venezuela | $0.10M |
22 | 🇲🇱 Mali | $0.06M |
Total | $16,290M |
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.
Rank | Region | Share of Rough Diamond Production (%) | Share of Rough Diamond Value (%) |
---|---|---|---|
1 | Africa | 51.4% | 66.4% |
2 | Europe | 34.9% | 32.9% |
3 | North America | 13.5% | 52.8% |
4 | South America | 0.2% | 2.4% |
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.
