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 Top 10 Biggest Companies in Brazil

In 2009, the at-the-time emerging economies of Brazil, Russia, India, and China held their first formal summits as members of BRIC (with South Africa joining in 2010).

Together, BRICS represents 26.7% of the world’s land surface and 41.5% of its population. By GDP ranking, they’re also some of the most powerful economies in the world.

But what drives their economies? We’re highlighting the top 10 biggest companies in each country, starting with Brazil.

What Are the Biggest Public Companies in Brazil?

Brazil isn’t just one of the largest and most diverse countries in the world, it is also an economic powerhouse.

With over 213 million people, Brazil is the sixth most populous country on Earth and the largest in Latin America. It’s also the wealthiest on the continent, with the world’s 12th-largest economy.

Once a colony focused on sugar and gold, Brazil rapidly industrialized in the 20th century. Today, it is a top 10 exporter of industrial steel, with the country’s economic strength coming chiefly from natural resources and financials.

Here are Brazil’s biggest public companies by market capitalization in October 2021:

Top 10 Companies (October 2021)CategoryMarket Cap (USD)
ValeMetals and Mining$73.03B
Petróleo BrasileiroOil and Gas$69.84B
AmbevDrinks$43.87B
Itaú UnibancoFinancial$41.65B

BTG PactualFinancial$25.01B
Banco Santander BrasilFinancial$24.70B
Rede D’Or Sao LuizHospital$23.79B
XP Inc.Financial$22.45B

At the top of the ranking is Vale, a metals and mining giant that is the world’s largest producer of iron ore and nickel. Also the operator of infrastructure including hydroelectricity plants, railroads, and ports, It consistently ranks as the most valuable company in Latin America.

Vale and second-ranking company Petróleo Brasileiro, Brazil’s largest oil producer, were former state-owned corporations that became privatized in the 1990s.

Finance in Brazil’s Top 10 Biggest Companies

Other than former monopolies, the top 10 biggest companies in Brazil highlight the power of the banking sector.

Five of the 10 companies with a market cap above $20 billion are in the financial industry.

They include Itaú Unibanco, the largest bank in the Southern Hemisphere, and Banco Santander Brasil, the Brazilian subsidiary of Spanish finance corp.

Another well-known subsidiary is brewing company Ambev, which produces the majority of the country’s liquors and also bottles and distributes PepsiCo products in much of Latin America. Ambev is an important piece of Belgian drink juggernaut Anheuser-Busch InBev, which is one of the world’s largest 100 companies.

Noticeably missing from the top 10 list are companies in the agriculture sector, as Brazil is the world’s largest exporter of coffee, soybeans, beef, and ethanol. Many multinational corporations have Brazilian subsidiaries or partners for supply chain access, which has recently put a spotlight on Amazon deforestation.

Metals are all around us, from our phones and cars to our homes and office buildings.

While we often overlook the presence of these raw materials, they are an essential part of the modern economy. But obtaining these materials can be a complex process that involves mining, refining, and then converting them into usable forms.

So, how much metal gets mined in a year?

Metals vs Ores

Before digging into the numbers, it’s important that we distinguish between ores and metals.

Ores are naturally occurring rocks that contain metals and metal compounds. Metals are the valuable parts of ores that can be extracted by separating and removing the waste rock. As a result, ore production is typically much higher than the actual metal content of the ore. For example, miners produced 347 million tonnes of bauxite ore in 2019, but the actual aluminum metal content extracted from that was only 62.9 million tonnes.

Here are all the metals and metal ores mined in 2019, according to the British Geological Survey:

Metal/OreQuantity Mined (tonnes)% of Total
Iron Ore3,040,000,00093.57%
Industrial Metals207,478,4866.39%
Technology and Precious Metals1,335,8480.04%
Total3,248,814,334100%

Miners produced roughly three billion tonnes of iron ore in 2019, representing close to 94% of all mined metals. The primary use of all this iron is to make steel. In fact, 98% of iron ore goes into steelmaking, with the rest fulfilling various other applications.

Industrial and technology metals made up the other 6% of all mined metals in 2019. How do they break down?

Industrial Metals

From construction and agriculture to manufacturing and transportation, virtually every industry harnesses the properties of metals in different ways.

Here are the industrial metals we mined in 2019.

MetalQuantity Mined (tonnes)% of Total
Aluminum62,900,00030%
Manganese Ore56,600,00027%
Chromium Ores and Concentrates38,600,00019%
Copper20,700,00010%
Zinc12,300,0006%
Titanium (Titanium Dioxide Content)6,300,0003%
Lead4,700,0002%
Nickel2,702,0001%
Zirconium Minerals (Zircon)1,337,0001%
Magnesium1,059,7361%
Strontium220,0000.11%
Uranium53,4000.03%
Bismuth3,7000.002%
Mercury2,4000.001%
Beryllium2500.0001%
Total207,478,486100%

Percentages may not add up to 100 due to rounding.

It’s no surprise that aluminum is the most-produced industrial metal. The lightweight metal is one of the most commonly used materials in the world, with uses ranging from making foils and beer kegs to buildings and aircraft parts.

Manganese and chromium rank second and third respectively in terms of metal mined, and are important ingredients in steelmaking. Manganese helps convert iron ore into steel, and chromium hardens and toughens steel. Furthermore, manganese is a critical ingredient of lithium-manganese-cobalt-oxide (NMC) batteries for electric vehicles.

Although copper production is around one-third that of aluminum, copper has a key role in making modern life possible. The red metal is found in virtually every wire, motor, and electrical appliance in our homes and offices. It’s also critical for various renewable energy technologies and electric vehicles.

Technology and Precious Metals

Technology is only as good as the materials that make it.

Technology metals can be classified as relatively rare metals commonly used in technology and devices. While miners produce some tech and precious metals in large quantities, others are relatively scarce.

MetalQuantity Mined in 2019 (tonnes)% of Total
Tin305,00023%
Molybdenum275,00021%
Rare Earth Elements220,00016%
Cobalt123,0009%
Lithium97,5007%
Tungsten91,5007%
Vanadium81,0006%
Niobium57,0004%
Cadmium27,5002%
Tantalum27,0002%
Silver26,2612%
Gold3,3500.3%
Indium8510.06%
Platinum Group Metals4570.03%
Gallium3800.03%
Rhenium490.004%
Total1,335,848100.00%

Percentages may not add up to 100 due to rounding.

Tin was the most-mined tech metal in 2019, and according to the International Tin Association, nearly half of it went into soldering.

It’s also interesting to see the prevalence of battery and energy metals. Lithium, cobalt, vanadium, and molybdenum are all critical for various energy technologies, including lithium-ion batteries, wind farms, and energy storage technologies. Additionally, miners also extracted 220,000 tonnes of rare earth elements, of which 60% came from China.

Given their rarity, it’s not surprising that gold, silver, and platinum group metals (PGMs) were the least-mined materials in this category. Collectively, these metals represent just 2.3% of the tech and precious metals mined in 2019.

A Material World

Although humans mine and use massive quantities of metals every year, it’s important to put these figures into perspective.

According to Circle Economy, the world consumes 100.6 billion tonnes of materials annually. Of this total, 3.2 billion tonnes of metals produced in 2019 would account for just 3% of our overall material consumption. In fact, the world’s annual production of cement alone is around 4.1 billion tonnes, dwarfing total metal production.

The world’s appetite for materials is growing with its population. As resource-intensive megatrends such as urbanization and electrification pick up the pace, our material pie will only get larger.
