Re-Awakening of the Golden Triangle

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.

Uranium

Charted: Global Uranium Reserves, by Country

We visualize the distribution of the world’s uranium reserves by country, with 3 countries accounting for more than half of total reserves.

There can be a tendency to believe that uranium deposits are scarce from the critical role it plays in generating nuclear energy, along with all the costs and consequences related to the field.

But uranium is actually fairly plentiful: it’s more abundant than gold and silver, for example, and about as present as tin in the Earth’s crust.

We visualize the distribution of the world’s uranium resources by country, as of 2021. Figures come from the World Nuclear Association, last updated on August 2023.

Ranked: Uranium Reserves By Country (2021)

Australia, Kazakhstan, and Canada have the largest shares of available uranium resources—accounting for more than 50% of total global reserves.

But within these three, Australia is the clear standout, with more than 1.7 million tonnes of uranium discovered (28% of the world’s reserves) currently. Its Olympic Dam mine, located about 600 kilometers north of Adelaide, is the the largest single deposit of uranium in the world—and also, interestingly, the fourth largest copper deposit.

Despite this, Australia is only the fourth biggest uranium producer currently, and ranks fifth for all-time uranium production.

🇺🇦 Ukraine2%107K
🌍 Rest of World9%524K

Figures are rounded.

Outside the top three, Russia and Namibia both have roughly the same amount of uranium reserves: about 8% each, which works out to roughly 470,000 tonnes.

South Africa, Brazil, and Niger all have 5% each of the world’s total deposits as well.

China completes the top 10, with a 3% share of uranium reserves, or about 224,000 tonnes.

A caveat to this is that current data is based on known uranium reserves that are capable of being mined economically. The total amount of the world’s uranium is not known exactly—and new deposits can be found all the time. In fact the world’s known uranium reserves increased by about 25% in the last decade alone, thanks to better technology that improves exploration efforts.

Meanwhile, not all uranium deposits are equal. For example, in the aforementioned Olympic Dam, uranium is recovered as a byproduct of copper mining occurring at the same site. In South Africa, it emerges as a byproduct during treatment of ores in the gold mining process. Orebodies with high concentrations of two substances can increase margins, as costs can be shared for two different products.
