Silver More Than Precious

Silver’s Role in the New Energy Era (Part 3 of 3)

Silver is one of the first metals that humans discovered and used. Its extensive use throughout history has linked its name to its monetary value. However, as we have advanced technologically, so have our uses for silver. In the future, silver will see a surge in demand from solar and electric vehicle (EV) technologies.

Part 1 and Part 2 of the Silver Series showcased its monetary legacy as a safe haven asset as a precious metal and why now is its time to shine.

Part 3 of the Silver Series comes to us from Endeavour Silver, and it outlines silver’s role in the new energy era and how it is more than just a precious metal.

A Sterling Reputation: Silver’s History in Technologies

Silver along with gold, copper, lead and iron, was one of the first metals known to humankind. Archaeologists have uncovered silver coins and objects dating from before 4,000 BC in Greece and Turkey. Since then, governments and jewelers embraced its properties to mint currency and craft jewelry.

This historical association between silver and money is recorded across multiple languages. The word silver itself comes from the Anglo-Saxon language, seolfor, which itself comes from ancient Germanic silabar.

Silver’s chemical symbol, “Ag”, is an abbreviation of the Latin word for silver, argentum. The Latin word originates from argunas, a Sanskrit word which means shining. The French use argent as the word for money and silver. Romans bankers and silver traders carried the name argentarius.

While silver’s monetary meanings still stand today, there have been hints of its use beyond money throughout history. For centuries, many cultures used silver containers and wares to store wine, water, and food to prevent spoilage.

During bouts of bubonic plague in Europe, children of wealthy families sucked on silver spoons to preserve their health, which gave birth to the phrase “born with a silver spoon in your mouth.”

Medieval doctors invented silver nitrate used to treat ulcers and burns, a practice that continues to this day. In the 1900s, silver found further application in healthcare. Doctors used to administer eye drops containing silver to newborns in the United States. During World War I, combat medics, doctors, and nurses would apply silver sutures to cover deep wounds.

Silver’s shimmer also made an important material in photography up until the 1970s. Silver’s reflectivity of light made it popular in mirror and building windows.

Now, a new era is rediscovering silver’s properties for the next generation of technology, making the metal more than precious.

Silver in the New Energy Era: Solar and EVs

Silver’s shimmering qualities foreshadowed its use in renewable technologies. Among all metals, silver has the highest electrical conductivity, making it an ideal metal for use in solar cells and the electronic components of electric vehicles.

Silver in Solar Photovoltaics

Conductive layers of silver paste within the cells of a solar photovoltaic (PV) cell help to conduct the electricity within the cell. When light strikes a PV, the conductors absorb the energy and electrons are set free.

Silver’s conductivity carries and stores the free electrons efficiently, maximizing the energy output of a solar cell. According to one study from the University of Kent, a typical solar panel can contain as much as 20 grams of silver.

As the world adopts solar photovoltaics, silver could see dramatic demand coming from this form of renewable energy.

Silver in Electric Vehicles

Silver’s conductivity and corrosion resistance makes its use in electronics critical, and electric vehicles are no exception. Virtually every electrical connection in a vehicle uses silver.

Silver is a critical material in the automotive sector, which uses over 55 million ounces of the metal annually. Auto manufacturers apply silver to the electrical contacts in powered seats and windows and other automotive electronics to improve conductivity.

A Silver Intensive Future

A green future will require metals and will redefine the role for many of them. Silver is no exception. Long known as a precious metal, silver also has industrial applications metal for an eco-friendly future.

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 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.
