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.
Gold: 49 g/t
Silver: 2,406 g/t
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.
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.
- 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.
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.
Gold in Nevada: The Real Golden State
Nevada accounts for 84% of U.S. gold production today. Here’s a look at the state’s rich history, its prolific production, and what the future may hold.
The Real Golden State: Gold Production in Nevada
Thanks to the world famous silver discoveries of the 19th century that unveiled Nevada’s precious metal potential, the state today is known by many as “The Silver State”.
However, it’s possible that nickname may need to be updated. In the last few decades, Nevada has become a prolific gold producer, accounting for 84% of total U.S. gold production each year.
Today’s infographic from Corvus Gold showcases why Nevada may have a better case for deserving California’s nickname of the “Golden State”: we look at the state’s gold production, exploration potential, and even its rich history.
A Defining Era for the American West
The discovery of the Comstock silver lode in 1859 sparked a silver rush of prospectors to Nevada, scrambling to stake their claims. News of the discovery spread quickly throughout the United States, drawing thousands into Nevada for one of the largest rushes since the California Gold Rush in 1849. Mining camps soon thrived and eventually became towns, a catalyst that helped turn the territory into an official state by 1864.
Interestingly, many of the early mines also produced considerable quantities of gold, indicating there was more to the state than just silver.
- The Comstock Lode: 8,600,000 troy ounces (270t) of gold until 1959
- The Eureka district: 1,200,000 troy ounces (37t) of gold
- The Robinson copper mine: 2,700,000 troy ounces (84t) of gold
The Comstock Lode is notable not just for the immense fortunes it generated but also the large role those fortunes had in the growth of Nevada and San Francisco.
In fact, there was so much gold and silver flowing into San Francisco, the U.S. Mint opened a branch in the city to safely store it all. Within the first year of its operation, the San Francisco Mint turned $4 million of gold bullion into coins for circulation.
While California gold rushes became history, Nevada mining was just beginning and would spur the development of modern industry. In 2018, California produced 140,000 troy ounces of gold, just a fraction of the 5.58 million oz coming out of Nevada’s ground.
Nevada Gold Mining Geology: Following the Trends
There are three key geological trends from where the majority of Nevada’s gold comes from.
- Cortez Trend
- Carlin Trend
- Walker Lane Trend
Together these trends contributed nearly 170 million ounces of gold produced in Nevada between 1835 and 2018, making it the United States’ most productive gold jurisdiction, if not the world’s.
The bulk of production comes from the Cortez and Carlin Trends, where mines extract low grade gold from a particular type of mineral deposit, the Carlin Type Gold deposit. It was the discovery and technology used for processing these “invisible” deposits that would turn Nevada into the golden powerhouse of production.
Today, the world’s largest gold mining complex, Nevada Gold Mines, is located on the Carlin Trend. The joint venture between Barrick and Newmont comprises eight mines, along with their infrastructure and processing facilities.
Despite the prolific production of modern mines in the state, more discoveries will be needed to feed this production pipeline—and discoveries are on the decline in Nevada.
Looking to the Future Through the Past: The Walker Lane Trend
The future for gold mining in Nevada may lie in the Walker Lane Trend. This trend is host to some of the most recent gold discoveries, and has attracted the interest of major mining companies looking to conduct exploration, and eventually, production.
Walker Lane stands out with exceptional high-grades, growing reserves, and massive discovery potential. It also played an integral role in the history of the state beginning with the 1859 discovery of the Comstock Lode, and it seems likely to continue doing so in the future.

This massive infographic reveals the dramatic scale of 2019 non-fuel mineral global production.
All the World’s Metals and Minerals in One Visualization
We live in a material world, in that we rely on materials to make our lives better. Without even realizing it, humans consume enormous amounts of metals and minerals with every convenient food package, impressive building, and technological innovation.
Every year, the United States Geological Service (USGS) publishes commodity summaries outlining global mining statistics for over 90 individual minerals and materials. Today’s infographic visualizes the data to reveal the dramatic scale of 2019 non-fuel mineral production.
Read all the way to the bottom; the data will surprise you.
Non-Fuel Minerals: USGS Methodology
A wide variety of minerals can be classified as “non-fuel”, including precious metals, base metals, industrial minerals, and materials used for construction.
Non-fuel minerals are those not used for fuel, such as oil, natural gas and coal. Once non-fuel minerals are used up, there is no replacing them. However, many can be recycled continuously.
The USGS tracked both refinery and mine production of these various minerals. This means that some minerals are the essential ingredients for others on the list. For example, iron ore is critical for steel production, and bauxite ore gets refined into aluminum.
Top 10 Minerals and Metals by Production
Sand and gravel are at the top of the list of non-fuel mineral production.
As these materials are the basic components for the manufacturing of concrete, roads, and buildings, it’s not surprising they take the lead.
|Rank||Metal/Mineral||2019 Production (millions of metric tons)|
|#1||Sand and Gravel||50,000|
|#3||Iron and Steel||3,200|
These materials fertilize the food we eat, and they also form the structures we live in and the roads we drive on. They are the bones of the global economy.
Let’s dive into some more specific categories covered on the infographic.
While cement, sand, and gravel may be the bones of global infrastructure, base metals are its lifeblood. Their consumption is an important indicator of the overall health of an economy.
Base metals are non-ferrous, meaning they contain no iron. They are often more abundant in nature and sometimes easier to mine, so their prices are generally lower than precious metals.
|Rank||Base Metal||2019 Production (millions of metric tons)|
Base metals are also the critical materials that will help to deliver a green and renewable future. The electrification of everything will require vast amounts of base metals to make everything from batteries to solar cells work.
Gold and precious metals grab the headlines because of their rarity — and their production shows just how rare they are.
|Rank||Precious Metal||2019 Production (metric tons)|
While metals form the structure and veins of the global economy, ultimately it is humans and animals that make the flesh of the world, driving consumption patterns.
A Material World: A Perspective on Scale
The global economy’s appetite for materials has quadrupled since 1970, faster than the population, which only doubled. On average, each human uses more than 13 metric tons of materials per year.
In 2017, it’s estimated that humans consumed 100.6B metric tons of material in total. Half of the total comprises sand, clay, gravel, and cement used for building, along with the other minerals mined to produce fertilizer. Coal, oil, and gas make up 15% of the total, while metal makes up 10%. The final quarter are plants and trees used for food and fuel.
