Red Lake: The High-Grade Gold Capital of the World

Every major gold producing country has an iconic gold producing trend that is synonymous with prosperity. South Africa has the Witwatersrand Basin and the United States has the Carlin Trend in Nevada.

While Canada has had many prolific gold producing regions over the years, including many famous gold rushes, lately the gold capital of Canada rests in Red Lake, Ontario. It is here – in some of the world’s richest gold deposits – that the yellow metal is famously produced at the astonishing rate of two troy ounces per tonne.

The Geology

Like much gold in Ontario and Quebec, deposits are found in a greenstone formation at Red Lake.

Most of the gold production in the district has come from structurally controlled vein-type gold deposits near regional mafic volcanic-sediment contact or ‘breaks’.

Major gold camps in the Timmins and Kirkland Lake areas of northeastern Ontario also show a close association with similar breaks. However, Red Lake’s major discovery in 1995 of the High Grade Zone makes it about 50 years “newer” for exploration potential.

The History

Gold was discovered on the shores of Red Lake by L.B. Howey in 1925. Word spread quickly and the town experienced a sudden surge in economic, industrial, and population growth. People travelled by dog team, on foot, or by open cockpit airplanes to seek their fortune. By 1936, Red Lake’s Howey Bay was the busiest airport in the world, with more flights taking off and landing per hour than any other.

Between Howey and the Hasaga Mine next door, a total of 600,000 oz gold was produced. But, it would be later discoveries that would make Red Lake the future capital of high-grade gold.

In 1938, the mill started at the Madsen Mine. It would produce for the next 36 years. In 1948 and 1949 respectively, the Arthur White Mine (later Dickenson and Red Lake) mine and then the Campbell Mine went into production.

The Challenge

In the 1989, Rob McEwen gained control of an underperforming mine previously known as the Arthur White Mine and then the Dickenson Mine. McEwen, the CEO of Goldcorp, knew the mine could have similar grade and potential to the surrounding mines such as the Campbell Mine.

In 1995, the High Grade Zone was discovered. Nine drill holes averaged 9.08 ounces of gold over 7.5 feet, but the company still found the overall geology to be challenging.

In 2000 at PDAC, Mr. McEwen launched the “Goldcorp Challenge” and posted decades of geological data on its Red Lake Mine to its corporate website. Geologists, scientists, and engineers from around the world were encouraged to examine the data and submit proposals as to where the next six million ounces of gold would be found. There was a purse of $575,000 USD up for grabs. It was viewed 475,000 times and 1,400 prospectors from 51 countries registered as participants.

Today at Red Lake

Since 1925, there have been 28 operating mines and 28 million oz of gold produced at Red Lake. The majority has come from four mines: Red Lake (Dickenson), Campbell, Madsen, and Cochenour.

The biggest producing mine in 2014 was Goldcorp’s Red Lake Mine, which produced 414,400 oz. The High Grade Zone is the backbone of the operation, with an average grade of more than two ounces per tonne.

There are several current projects of note in the district:

  • Rubicon Minerals: Rubicon’s Phoenix / F2 Deposit is expected to go into production in mid-2015. It is expected (conservatively) to produce 2.19 million oz with a head grade of 8.1 g/t Au
  • Gold Canyon: Gold Canyon’s Springpole project has 4.41 million oz gold (M&I) and 0.69 million oz gold (Inf.) just to the northeast of Red Lake
  • Goldcorp: Aside from Goldcorp’s operating mines, Goldcorp is currently working on bringing to life the Cochenour / Bruce Channel deposit. Under Red Lake, it has a projected mine life of 20 years and >250,000 oz/yr production. A high speed tram will connect this with the mill.

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.

🌍 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.
