Understanding the Role of Copper Today

Modern economies rely on infrastructure, transportation, healthcare, construction, and energy utilities. Copper is critical to each one of these industries—supporting economic growth, urbanization, higher living standards, and a sustainable future.

How does copper do all this?

The element has five key properties that make it an integral part of the modern economy:

  1. High conductivity
  2. Pressure resistance
  3. Corrosion resistance
  4. Antimicrobial properties
  5. Ductility

Let’s look at how these properties factor into major uses of the red metal today.

Copper Builds: Construction and Infrastructure

The construction and infrastructure industries use more than 40% of all copper produced. Copper’s properties make it the optimal choice for various construction activities:

  • Roofing: Copper’s wind resistance, aesthetic appeal, and sustainability make it a great roofing material.
  • Tubing: Residential heating and water systems use copper tubes for copper’s high thermal conductivity and antimicrobial properties.
  • Electric grids: The generation, transmission, distribution, and consumption of electricity all rely on copper wiring for its electrical conductivity and malleability.

In addition, copper lightning conductors are the longstanding protectors of buildings when lightning strikes—a further testament to its electrical properties.

Despite its widespread usage, copper remains highly affordable. Without copper, powering, wiring, and protecting our homes would prove costly and difficult.

Copper Moves: Transportation

From gas-powered cars and electrical vehicles (EVs) to trains and airplanes, copper is an essential part of our daily commute.

Here are some interesting uses of copper in transportation:

Means of TransportationWhere Copper is UsedCopper's Role
AirplanesWiring and equipment
  • A single Boeing 747-200 Jet contains 632,000 feet of copper wire.

  • Copper is used to make busbars and lock wires for aircraft.

  • Landing gear parts and bearings make use of copper alloys to withstand high pressures.
Electric Vehicles (EVs)Wiring, voltage transmission, and motors
  • Electric vehicles can contain up to 368 kilograms (813 lbs) of copper, depending on their size and type.

  • EVs rely on copper’s electrical conductivity in batteries, wiring systems, and charging stations.

  • High-speed trains use copper alloys to maintain electrical contact at high speeds.
Cars and other modesWiring, radiators, brake-tubing, and motors
  • The average luxury car contains 1.6 km (5,249 feet) of copper.

  • Using copper in motors increases efficiency, resulting in higher power generation and longer distances.

  • Brake-tubing systems utilize copper’s anti-corrosive and pressure-resistant properties.

  • Copper makes heat radiators smaller, lighter, and more affordable.

As the global population grows, more transportation services will be required—and copper will continue to play a crucial role.

Copper Cares: Healthcare and Hospitals

Did you know that copper can kill 99.9% of E.Coli within two hours of exposure?

This, alongside the ongoing COVID-19 pandemic, makes copper’s antimicrobial properties and healthcare applications more important than ever.

Copper helps us lead healthier lives in many ways.

Where Copper is FoundCopper's Role
HospitalsCopper’s ability to kill bacteria improves the safety of high-touch surfaces such as doorknobs and bed handles.
Daily DietsCopper is vital to the normal development of the brain, and adults require 1-2mg of copper in their daily diets.

More than 500 antimicrobial copper alloys are registered with the U.S. Environmental Protection Agency. With further research, copper could play an even bigger role in healthcare.

Copper Strengthens: Jewelry and Coinage

Copper’s durability and aesthetic appeal make it ideal for usage in jewelry and coinage, where it’s present in significant quantities.

For instance, 18K gold jewelry typically contains 75% gold, 15% silver, and 10% copper. Not only does copper strengthen gold and silver jewelry, but its alloys (brass and bronze) are also commonly used to make jewelry items that are affordable and appealing.

Furthermore, many of the coins we use are made from copper and its alloys. To be precise, two properties of copper are key to producing durable and safe coins:

  1. Corrosion Resistance: Copper-nickel alloy coins do not tarnish.
  2. Electrical Conductivity: Copper-nickel coins have specific electronic signatures that help prevent fraud in vending and coin-handling machines.

Copper Comforts: Homes and Households

The average single-family home contains around 200 kilograms (439 lbs) of copper.

Here’s how it breaks down, along with the amount of copper in general appliances:

Appliance/MaterialAmount of Copper Contained (kg)
Building Wire88.5
Plumbing tubes and fittings68.5
Air conditioners 23.5
Heat Pumps21.7
Built-in appliances and other hardware21.0
Dishwashers2.2
Refrigerators2.1

But that’s not all.

In addition to home appliances, copper also plays an important role in objects that we use on a daily basis. According to BBC, a typical iPhone contains 15 grams of copper on average—approximately 10% of the phone’s weight.

Copper is an integral part of the modern economy today. Its unique properties enable urbanization and economic development at low costs—and the story doesn’t end here.

Why Copper Tomorrow?

As the world transitions towards a cleaner energy mix, copper will be an essential material in empowering a more sustainable future.

Copper in Renewable Energy

According to McKinsey, a whopping 73% of global power generation will come from renewable energy sources by 2050—and copper has a significant role to play in this transition.

Solar and wind energy farms are heavily dependent on copper. Cabling and heat-exchange in solar and wind farms are the primary applications of copper in renewable energy generation.

For starters, wind farms can contain anywhere between 4 to 15 million pounds of copper. Moreover, solar photovoltaic farms require 9,000 pounds of copper per megawatt of energy. To put that into context, India’s solar power generation capacity is 31,696 megawatts—which alone would require about 322 million pounds of copper.

Copper in Electric Vehicles

As the standard benchmark for electrical conductivity, copper is indispensable for EVs. The growing EV market could bolster copper demand in the near future.

Copper is used in EV batteries, coils, wiring, and charging stations. As per current growth projections, by 2030, more than 250,000 tonnes of copper will be needed as part of the windings in electric traction motors in on-road EVs.

The transition to clean energy, coupled with urbanization and economic development, implies that copper is critical for the future.

However, copper’s importance to the future is a double-edged sword and raises concerns about the sustainability of its supply—will there be enough?

Copper Forever: Sustainable Material

From the 5.8 trillion pounds of known copper resources, only 12% have been mined throughout history—and thanks to copper’s recyclability, almost all of that is still in circulation.

Not only does recycled copper offer the same quality and benefits as newly mined copper, but it also saves a massive 40 million tonnes of CO2 emissions annually. Additionally, copper recycling uses 80-90% less energy than mining, and a total of 8.5 million tonnes of the red metal are produced from recycled scrap each year.

Copper’s recyclability makes it reusable for years to come, complementing the path to sustainable development.

Copper: Critical Today, Tomorrow, and Forever

The exceptional properties of copper allow for widespread applications, which continue to grow as the world shifts towards clean energy.

And since we need copper for all aspects of life, its demand will always persist.

Zinc: The Essential, Sustainable, and Versatile Metal

Zinc’s widespread uses in the modern economy make it essential for urbanization and economic development. Learn more about the uses of zinc in this infographic.

Uses of zinc in the modern economy

What would the world be like without zinc?

Long-running TV show The Simpsons showed us one depiction what this could look like—but in order to truly gauge the impact of the metal on our lives, we need a better understanding of the uses of zinc and its role in modern life.

Zinc’s Role in Modern Life

Zinc is a naturally occurring mineral that is present all around us: from our bodies, foods, and medicines to the buildings we live and work in. Despite this, very few people actually know how it gets there.

This infographic comes to us from Trilogy Metals and looks at the widespread uses of zinc in the modern economy, from construction and infrastructure to health, farming, and green energy.

The Zinc Supply Chain

Zinc is the fourth most used metal in the world behind iron, aluminum, and copper.

Before zinc makes it into its various applications, miners have to extract the metal from the ground. So which countries are the top producers of zinc?

CountryMined Zinc Production (2019, metric tons)Share of World Production (2019)
China4,300,00033%
Peru1,400,00011%
Australia1,300,00010%
Total7,000,00054%

China, Peru, and Australia account for 7 million tons or 54% of the world’s zinc production. Although the U.S. is among the world’s top five zinc producers, it only produced 780,000 metric tons of the silvery metal in 2019—roughly one-fifth of China’s zinc production.

We don’t always use zinc in its raw, metallic form; it is often refined and processed first.

The United States is lagging in the production of refined zinc, with a net import reliance of 87%. As the demand for zinc rises, local sources of mined and refined zinc will be valuable for import-reliant countries like the U.S.

But where does the demand for zinc come from, and what makes it so valuable?

Zinc Strengthens: Infrastructure and Alloys

Zinc is also referred to as the “galvanizing metal” for its role in protecting steel. In fact, galvanizing accounts for around 50% of total annual zinc usage.

Galvanizing with zinc improves steel in various ways:

  • Strength
    Adding zinc as a protective layer provides steel with higher impact strength
  • Longevity
    The zinc coating on galvanized steel lasts around 50 years, allowing structures made from steel to last longer
  • Corrosion-resistance
    Zinc acts as a sacrificial coating for the underlying steel, protecting it from corrosion and rust

From steel-frame buildings and bridges to furniture and automotive body parts, galvanized steel plays a critical role in building sustainable infrastructure.

According to a study by the National Association of Corrosion Engineers, corrosion costs the world $2.5 trillion annually. Given that only 6% of all steel produced annually is galvanized, increasing the use of zinc-coated steel could potentially reduce this economic impact.

Zinc in Alloys

Besides galvanizing, alloying is one of the most common uses of zinc. Zinc’s ability to provide other metals with strength and corrosion-resistance makes it an effective alloying material.

Around 25% of all zinc is used in alloys to create metals such as brass, which are commonly found in household fixtures, plumbing fittings, electronic devices, and musical instruments. Additionally, zinc alloys have a range of engineering applications, thanks to their rigidity, strength, and conductivity.

Zinc Improves: Health and Productivity

Zinc is not only a natural part of our body but also a critical nutrient for our immune systems.

The UN has labeled zinc a “life-saving commodity”—increased access to zinc could prevent 200,000 childhood deaths annually. Zinc is an essential nutrient for various reasons:

  • Helps fight infections
  • Vital for taste and smell
  • Enhances memory and thinking

Furthermore, zinc oxide, a compound produced by oxidizing metallic zinc, is a key ingredient in various health and medicinal products including cosmetics, food additives, and anti-fungal creams.

Zinc in Crops

Besides its critical role in the human body, zinc is also an essential micronutrient for plants.

When farmers add zinc to soils in the form of zinc oxide, it helps their crops resist tough conditions such as drought, salinity, and heat. A stable supply of zinc can also help crops reach higher productivity and yield levels.

As the global population grows, crop productivity will be important in addressing the higher demand for food. Zinc has an essential role to play in making crops resilient and more productive.

Zinc Supports: The Clean Energy Transition

The transition to a low-carbon, clean energy future will be mineral intensive—and zinc is playing a key role in boosting this transition.

Zinc-air batteries are quickly emerging as an efficient clean energy-storage solution that can provide renewable electricity in remote regions. Three factors make zinc-air batteries an integral part of the clean energy transition:

  • Efficient for storing non-constant renewable energy
  • Affordable because of their use of zinc
  • High energy density

In fact, NantEnergy’s zinc-air energy storage systems have already made a significant impact on sustainability.

  • Avoided 50,000 tons of CO2 emissions
  • Reduced 4 million liters of diesel fuel use
  • Provided 200,000 people with access to power

Additionally, zinc protects the steel used to build renewable energy infrastructure. Offshore wind masts are made from zinc thermal sprayed steel to prevent corrosion, and solar PV panels use support structures made of galvanized steel.

Zinc in the Circular Economy

Zinc is part of a circular economy that restores, recovers, and reuses.

For starters, zinc is fully recyclable—it can be recycled from scrap without losing any of its properties. As a matter of fact, 60% of all produced zinc is still in use. Moreover, zinc’s 45% end-of-life recycling rate means that almost half of all the zinc produced is recycled after final-usage.

Zinc’s contribution to the circular economy will help minimize waste and improve resource sustainability as our material needs grow.

Zinc: Strengthening the Path to a Sustainable Future

The uses of zinc today are widespread and make an enormous impact on almost every aspect of our modern lives. Just as our present world could not function without zinc, so will our future.

As we transition to a cleaner world, zinc will continue strengthening, improving, and supporting the modern economy.

How Precious Metals Royalty and Streaming Companies Create Value

Discover how royalty and streaming companies offer a unique way to invest in precious metals and the mining industry.

Published

Royalty and Streaming Companies outperform gold and GDX

Gold and Silver Royalty and Streaming Companies

Investing in precious metals often seems like it boils down to either buying the physical gold or silver or investing in shares of specific mining companies, both with their own very distinct advantages and risks.

Rather than having to settle for the simplicity of bullion or extensive research in individual mining companies, precious metals royalty and streaming companies provide investors with exposure to a diversified portfolio of miners’ revenues and produced metals.

These companies are not operators of mines. Instead, they seek to find undiscovered value by financing and working directly with miners to forge agreements that provide their shareholders with steady exposure to precious metals production.

This infographic from Empress Royalty outlines exactly how gold and silver royalty and streaming companies operate, and how they mitigate risk and create value for their shareholders.

What Do Precious Metals Royalty and Streaming Companies Do?

Royalty and streaming companies are an important part of the mining industry’s financial ecosystem, as they provide capital to mine operators and explorers in exchange for a percentage of revenue or metals produced from the mine.

Mining companies receiving this investment are able to further develop or expand projects, providing greater returns for both their shareholders and the companies with royalties and stream agreements on the projects.

These agreements typically last for the life of a mine, providing steady cash flow to royalty and stream holders while cutting out various risks associated with mining companies and operations.

“What it takes in the royalty business is patience and cash.”
– Pierre Lassonde, co-founder of the first royalty and streaming company, Franco-Nevada

The Difference Between Royalty Agreements and Streams

Royalty agreements and streams have similarities in their structure, but ultimately have some key differences.

  • Royalty agreements, also called net smelter return (NSRs), provide the royalty holder a percentage of the mine’s revenue from production, typically around 1-3%. There are also other kinds of royalty agreements like net profits interests (NPIs), where the royalty holder receives a percentage of the profits rather than the revenue.
  • Streams provide the right to purchase a certain percent (typically 5-20%) of metal production directly from the mine. Typically, streams will have an already decided purchasing price for the metal, which is usually either a fixed dollar amount or a fixed percentage of the spot price.

Royalties are more common than streams as they provide cash directly to the royalty company rather than the option to buy the physical metal which then needs to be sold.

While royalty and streams differ in what is delivered, both kinds of agreements avoid operational costs as they receive cuts from the top line.

The Growing and Diverse Landscape of Royalty and Streaming

The niche sector of gold and silver royalties has changed greatly since the founding of the original royalty business, Franco-Nevada in 1980.

While still fairly small today, the subsector has grown to have more than 10 companies with a market cap of $100M USD each, with five surpassing the $1B mark.

Here are the top 10 royalty and streaming companies by market cap:

CompanyMarket Capitalization (USD)Forward Dividend Yield
Franco-Nevada$21.6B0.91%
Wheaton Precious Metals$17.8B1.20%
Royal Gold$7.1B1.12%
Osisko Gold Royalties$1.9B1.39%
Sandstorm Gold$1.3B0.00%
Maverix Metals$738.0M0.75%
Nomad Royalty$488.6M1.82%
Metalla Royalty and Streaming$368.3M0.37%
EMX Royalty Corporation$308.0B0.00%
Abitibi Royalties$237.9M0.78%

Source: Yahoo Finance

While the three big names of Franco-Nevada, Wheaton Precious Metals, and Royal Gold tend to focus on larger and more secure ounce-producing agreements, the newer precious metals royalty companies start out by establishing a few cash-flowing agreements in their portfolio.

After this, they can begin targeting more speculative agreements with developing or exploration projects which are typically worth smaller dollar amounts and are slightly riskier or further from production, but have the potential of undiscovered upside.

Some royalty companies don’t even deal with mining companies at all, and focus exclusively on buying royalty and stream agreements held by third party companies or prospectors.

How These Companies Reduce Risk and Capture Upside

By avoiding many of the operational costs, royalty and streaming companies cut out a large amount of risk that is typically associated with mining investments.

In precious metal bull markets, it’s typical to see mining company revenues rise alongside the prices of gold and silver.

While mining companies’ operational costs will also rise, royalty and stream holders simply reap the benefits of high margins as they sell their physical metals at higher prices, despite having acquired them at lower fixed prices according to their agreement.

Another key advantage royalty and streaming companies have is their ability to diversify their portfolios and be selective with their agreements. This allows them to escape concentrated jurisdictional or asset risk and make agreements with mines which are already producing or close to production.

Since royalties and streams tend to last as long as the associated mine is operational, the holders of these agreements also benefit from any increased production or lifespan.

Royalty and Streaming Companies: Stable Exposure to Metals

As precious metals royalty and streaming companies are able to carefully choose their agreements and are overall less exposed to price downturns, they provide investors with a more stable investment in gold and silver.

Royalty and streaming companies typically have dividend policies which ensure shareholders are consistently rewarded with rising dividends, while many gold and silver mining companies cut dividends aggressively during precious metal market downturns.

As they help finance new projects and expansions, royalty and streaming companies take advantage of high margins in a unique form of financial arbitrage while providing their shareholders with stable exposure to precious metals and mining operations.
