Golden Triangle in British Columbia

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.

Skeena Resources and IDM Mining have generously helped us to put together the story on the re-awakening of the famed Golden Triangle.

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:

KSM
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.

Red Chris
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 mining is a global business, with hundreds of mining companies digging for the precious metal in dozens of countries.

But where exactly are the largest gold mines in the world?

The above infographic uses data compiled from S&P Global Market Intelligence and company reports to map the top 10 gold-producing mines in 2021.

Editor’s Note: The article uses publicly available global production data from the World Gold Council to calculate the production share of each mine. The percentages slightly differ from those calculated by S&P.

The Top Gold Mines in 2021

The 10 largest gold mines are located across nine different countries in North America, Oceania, Africa, and Asia.

Together, they accounted for around 13 million ounces or 12% of global gold production in 2021.

#10Boddington🇦🇺 Australia 696,0000.6%
N/ATotalN/A13,393,84911.7%

Share of global gold production is based on 3,561 tonnes (114.5 million troy ounces) of 2021 production as per the World Gold Council.

In 2019, the world’s two largest gold miners—Barrick Gold and Newmont Corporation—announced a historic joint venture combining their operations in Nevada. The resulting joint corporation, Nevada Gold Mines, is now the world’s largest gold mining complex with six mines churning out over 3.3 million ounces annually.

Uzbekistan’s state-owned Muruntau mine, one of the world’s deepest open-pit operations, produced just under 3 million ounces, making it the second-largest gold mine. Muruntau represents over 80% of Uzbekistan’s overall gold production.

Only two other mines—Grasberg and Olimpiada—produced more than 1 million ounces of gold in 2021. Grasberg is not only the third-largest gold mine but also one of the largest copper mines in the world. Olimpiada, owned by Russian gold mining giant Polyus, holds around 26 million ounces of gold reserves.

Polyus was also recently crowned the biggest miner in terms of gold reserves globally, holding over 104 million ounces of proven and probable gold between all deposits.

How Profitable is Gold Mining?

The price of gold is up by around 50% since 2016, and it’s hovering near the all-time high of $2,000/oz.

That’s good news for gold miners, who achieved record-high profit margins in 2020. For every ounce of gold produced in 2020, gold miners pocketed $828 on average, significantly higher than the previous high of $666/oz set in 2011.

With inflation rates hitting decade-highs in several countries, gold mining could be a sector to watch, especially given gold’s status as a traditional inflation hedge.

The 50 Minerals Critical to U.S. Security

The U.S. aims to cut its greenhouse gas emissions in half by 2030 as part of its commitment to tackling climate change, but might be lacking the critical minerals needed to achieve its goals.

The American green economy will rely on renewable sources of energy like wind and solar, along with the electrification of transportation. However, local production of the raw materials necessary to produce these technologies, including solar panels, wind turbines, and electric vehicles, is lacking. Understandably, this has raised concerns in Washington.

In this graphic, based on data from the U.S. Geological Survey, we list all of the minerals that the government has deemed critical to both the economic and national security of the United States.

What are Critical Minerals?

A critical mineral is defined as a non-fuel material considered vital for the economic well-being of the world’s major and emerging economies, whose supply may be at risk. This can be due to geological scarcity, geopolitical issues, trade policy, or other factors.

In 2018, the U.S. Department of the Interior released a list of 35 critical minerals. The new list, released in February 2022, contains 15 more commodities.

Much of the increase in the new list is the result of splitting the rare earth elements and platinum group elements into individual entries rather than including them as “mineral groups.” In addition, the 2022 list of critical minerals adds nickel and zinc to the list while removing helium, potash, rhenium, and strontium.

The challenge for the U.S. is that the local production of these raw materials is extremely limited.

For instance, in 2021 there was only one operating nickel mine in the country, the Eagle mine in Michigan. The facility ships its concentrates abroad for refining and is scheduled to close in 2025. Likewise, the country only hosted one lithium mine, the Silver Peak Mine in Nevada.

At the same time, most of the country’s supply of critical minerals depends on countries that have historically competed with America.

China’s Dominance in Minerals

Perhaps unsurprisingly, China is the single largest supply source of mineral commodities for the United States.

Cesium, a critical metal used in a wide range of manufacturing, is one example. There are only three pegmatite mines in the world that can produce cesium, and all were controlled by Chinese companies in 2021.

Furthermore, China refines nearly 90% of the world’s rare earths. Despite the name, these elements are abundant on the Earth’s crust and make up the majority of listed critical minerals. They are essential for a variety of products like EVs, advanced ceramics, computers, smartphones, wind turbines, monitors, and fiber optics.

After China, the next largest source of mineral commodities to the United States has been Canada, which provided the United States with 16 different elements in 2021.

The Rising Demand for Critical Minerals

As the world’s clean energy transitions gather pace, demand for critical minerals is expected to grow quickly.

According to the International Energy Association, the rise of low-carbon power generation is projected to triple mineral demand from this sector by 2040.

The shift to a sustainable economy is important, and consequently, securing the critical minerals necessary for it is just as vital.
