Everything You Need to Know about VMS Deposits

People are often not aware of where their most prized devices really come from.

Phones, cars, and computers might not seem like the most natural objects. But the metals that make them come from natural processes deep in the earth’s crust – processes that have been going on for 3.4 billion years, and continue to this day.

Today’s visualization comes to us from Foran Mining Corp. and goes in depth to show how one type of mineral deposit, Volcanogenic Massive Sulphide or “VMS”, forms and is the primary source for many of the materials that make the modern world.

What is a VMS Deposit?

Volcanogenic Massive Sulphide (VMS) deposits are one of the richest sources of metals such as copper, lead, and zinc globally. VMS deposits can also produce economic amounts of gold and silver as byproducts of mining these deposits.

Currently, global metal production from VMS deposits account for 22% of zinc, 9.7% of lead, 6% of copper, 8.7% of silver and 2.2% of gold.

Where are VMS deposits found?

VMS deposits occur around the globe and often form in clusters or camps, following the tectonic plate boundaries in areas of ancient underwater volcanic activity.

Natural processes underway today are forming the VMS deposits of tomorrow. This gives scientists an incredible advantage in witnessing how VMS deposits form and gives a special advantage to geologists for what to look for.

Mineralization and Formation

The geological processes that form VMS deposits occur at the depths of the ocean and are associated with volcanic and/or sedimentary rocks.

At sections where the Earth’s crust is thin due to faulting or separation of tectonic plates, the magma heats up the ocean floor.

As the Earth’s crust heats up, the ground softens and allows heated magma to escape towards the ocean or crust contact, the early beginning of a volcano and the deposition of minerals into the ocean floor from magma. Also, the heated ground cracks and begins a process that draws in sea water into the crust which becomes super-heated and imbued with minerals. Black and white smokers expel this seawater back to the surface.

Black and white smokers exhale a mineral rich-plume that spreads out over the ocean floor. As it moves farther and farther away from its heat source, the plume precipitates minerals onto the ocean floor. Over time, the continual activity of the smokers and their mineral rich plumes create mineralized beds that become VMS deposits.

With the movement of the Earth’s tectonic plates, these mineral rich beds are transposed and can be found on land that was once underwater.

How Big Can VMS Deposits Get?

Current resource and historical production figures from 904 VMS deposits around the world average roughly 17 million tonnes (“Mt”), of which is approximately 1.7% copper, 3.1% zinc, and 0.7% lead.

A few giant mineral deposits (greater than 30 Mt) and several copper-rich and zinc-rich deposits of median tonnage (~2 Mt) skew the averages.

Several large VMS camps are known in Canada, including the Flin Flon, Bathurst and Noranda camps. The high-grade deposits within these camps are often in the range of five to 20 million tonnes of ore and can be much larger.

Meanwhile, approximately 90 VMS deposits have been discovered in the Iberian Pyrite Belt which runs through Portugal and Spain. Several of these are larger than 100 million tonnes, making this region one of the most significant hosts to VMS deposits in the world.

The Periodic Table of Endangered Elements

The building blocks for everything on Earth are made from 90 different naturally occurring elements.

This visualization made by the European Chemical Society (EuChemS), shows a periodic table of these 90 different elements, highlighting which ones are in abundance and which ones are in serious threat as of 2021.

On the graphic, the area of each element relates to its number of atoms on a logarithmic scale. The color-coding shows whether there’s enough of each element, or whether the element is becoming scarce, based on current consumption levels.

While these elements don’t technically run out and instead transform (except for helium, which rises and escapes from Earth’s atmosphere), some are being used up exceptionally fast, to the point where they may soon become extremely scarce.

One element worth pointing out on the graphic is carbon, which is three different colors: green, red, and dark gray.

  • Green, because carbon is in abundance (to a fault) in the form of carbon dioxide
  • Red, because it will soon cause a number of cataphoric problems if consumption habits don’t change
  • Gray because carbon-based fuels often come from conflict countries

The 10 Largest Gold Mines in the World, by Production

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.
