The Re-Awakening of the Golden Triangle
Many years ago, a remote and mountainous region in northwestern British Columbia gained considerable notoriety as an emerging mineral district. With a rich mining history, one of the world’s largest silver mines (Eskay Creek, discovered in 1988), and million ounce gold deposits – this area of incredible wealth became known as “The Golden Triangle”.
However, despite its obvious potential, the vast majority of land in this highly prospective region has been left mostly untouched by humans. A combination of factors, including low gold prices and a lack of infrastructure, has led to the area laying dormant for decades.
Today, things are changing dramatically. The Golden Triangle is a new hotbed for mineral discovery, and over 130 million ounces of gold, 800 million ounces of silver, and 40 billion lbs of copper have been found. The amazing part is that this is only scratching the surface of the region’s ultimate potential.
The New Gold Rush
Why is the Golden Triangle at the center of attention again? There are five main reasons:
1. New Deposits Found
The old adage is that the best place to find a new mine is near an existing one. Here are three major deposits in the Golden Triangle that have geologists and financiers buzzing:
Seabridge’s KSM Project is the largest gold project in the world. It recently received the green light from Canada’s federal government to go ahead in 2014.
A porphyry-style deposit, it has reserves of 38.8 million oz of gold, 10.2 billion lbs of copper, and 183 million oz of silver.
This $700 million copper and gold mine entered production in 2015.
Owned by Imperial Metals, it will be in production until 2043 based on current mine life estimates. In 2016 alone, it produced 83 million lbs of copper, 47,000 oz of gold, and 190,000 oz of silver.
Valley of the Kings
The latest, and perhaps most interesting, discovery in the Golden Triangle is slotted to reach commercial production in 2017.
The Valley of the Kings, unlike the above porphyry-style deposits, contains extremely high-grade gold. With 8.1 million ounces at a grade of 16.1 g/t, this deposit has some of the richest ore in the world.
2. New Infrastructure
In recent years, the Golden Triangle has received three massively important infrastructure upgrades:
- Paving of the Stewart-Cassiar Highway (North from Smithers)
- The opening of ocean port facilities for export of concentrate at Stewart
- Completion of a $700 million high-voltage transmission line to bring power into the Golden Triangle
3. Declining Snow Cover
Glacial ice and snow has been retreating in many parts of the region, revealing rocks never seen before by human eyes. Especially in a mineral-rich region such as the Golden Triangle, this is a very exciting prospect for mineral geologists.
4. A New Geological Explanation
The Golden Triangle region has complex geology that has befuddled explorers for decades – but recent work has made the picture much clearer. Geologist Jeff Kyba has put forth the following theory: geologic contact between Triassic age Stuhini rocks and Jurassic age Hazelton rocks is the key marker for copper-gold mineralization.
Most of the Triangle’s copper-gold deposits, whether they are large-scale porphyry and intrusion-related, are found within 2km of this contact. It’s been infamously named “The Red Line”, and this new interpretation of the region’s geology could contribute to BC’s next mega deposit.
5. Gold Price Recovery
Since the “sleepy” days of the Golden Triangle, gold prices have increased 3x, even after adjusting for inflation.
Combined with new infrastructure, exciting projects, and world-class mineral potential, and the Golden Triangle is awake again.
What’s Happening Today?
Today, the Golden Triangle is buzzing with activity.
- The Red Chris Mine is now in operation
- Valley of the Kings is entering production in 2017.
- KSM, the world’s largest gold deposit, is nearing potential construction.
- Historic mines like the Snip Mine and Granduc are being explored using modern methods.
- New high-grade gold is being found. Red Mountain and the old Premier Gold Mine are the sites of some of these discoveries.
- Dozens of companies are on the ground performing all phases of exploration.
Many types of mineral deposits are being tested for, including high-grade gold veins, large-scale porphyries, and VMS (volcanogenic massive sulphide) deposits.
The Golden Triangle is once again the center of the attention, and it could be poised to become one of the world’s most prolific concentrations of mineral wealth.
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.
