Mining is a technical field and requires a comprehension of many complex factors.
This includes everything from the characteristics of an orebody to the actual extraction method envisioned and used—and the devil is often found in these technical details.
Part 4: Evaluating Technical Risks and Project Quality
We’ve partnered with Eclipse Gold Mining on an infographic series to show you how to avoid common mistakes when evaluating and investing in mining exploration stocks.
Here is a basic introduction to some technical and project quality characteristics to consider when looking at your next mining investment.

Part 4: Technical Risks and Project Quality
So what must investors evaluate when it comes to technical risks and project quality?
Let’s take a look at four different factors.
1. Grade: Reliable Hen Vs. Golden Goose
Once mining starts, studies have to be adapted to reality. A mine needs to have the flexibility and robustness to adjust pre-mine plans to the reality of execution.
A “Golden Goose” will just blunder ahead and result in failure after failure due to lack of flexibility and hoping it will one day produce a golden egg.
Many mining projects can come into operation quickly based on complex and detailed studies of a mineral deposit. However, it requires actual mining to prove these studies.
Some mining projects fail to achieve nameplate tonnes and grade once production begins. However, a team response to varying grades and conditions can still make a mine into a profitable mine or a “Reliable Hen.”
2. Money: Piggy Bank vs. Money Pit
The degree of insight into a mineral deposit and the appropriate density of data to support the understanding is what leads to a piggy bank or money pit.
Making a project decision on poor understanding of the geology and limited information leads to the money pit of just making things work.
Just like compound interest, success across many technical aspects increases revenue exponentially, but it can easily go the other way if not enough data is used to make a decision to put a project into production.
3. Environment: Responsible vs. Reckless
Not all projects are situated in an ideal landscape for mining. There are environmental and social factors to consider. A mining company that takes into account these facts has a higher chance of going into production.
Mineral deposits do not occur in convenient locations and require the disruption of the natural environment. Understanding how a mining project will impact its surroundings goes a long way to see whether the project is viable.
4. Team: Orchestra vs. One-Man Band
Mining is a complex and technical industry that relies on many skilled professionals with clear leadership, not just one person doing all the work.
Geologists, accountants, laborers, engineers, and investor relations officers are just some of the roles that a CEO or management team needs to deliver a profitable mine. A good leader will be the conductor of the varying technical teams allowing each to play their best at the right time.
Mining 101: Mining Valuation and Methods
In order to further consider a mining project’s quality, it is important to understand how the company is valued and how it plans to mine a mineral resource.
There are two ways to look at the value of a mining project:
- The Discounted Cash Flow method estimates the present value of the cash that will come from a mining project over its life.
- In-situ Resource Value is a metric that values all the metal in the ground to give an estimate of the dollar value of those resources.
The location of the ore deposit and the quantity of its grade will determine what mining method a company will choose to extract the valuable ore.
- Open-pit mining removes valuable ore that is relatively near the surface of the Earth’s crust using power trucks and shovels to move large volumes of rock. Typically, it is a lower cost mining method, meaning lower grades of ore are economic to mine.
- Underground mining occurs when the ore body is too deep to mine profitably by open-pit. In other words, the quality of the orebody is high enough to cover the costs of complex engineering underneath the Earth’s crust.
When Technicals and Quality Align
This is a brief overview of where to begin a technical look at a mining project, but typically helps to form some questions for the average investor to consider.
Everything from the characteristics of an orebody to the actual extraction method will determine whether a project can deliver a healthy return to the investor.
Silver Through the Ages: The Uses of Silver Over Time
The uses of silver span various industries, from renewable energy to jewelry. See how the uses of silver have evolved in this infographic.
Silver is one of the most versatile metals on Earth, with a unique combination of uses both as a precious and industrial metal.
Today, silver’s uses span many modern technologies, including solar panels, electric vehicles, and 5G devices. However, the uses of silver in currency, medicine, art, and jewelry have helped advance civilization, trade, and technology for thousands of years.
The Uses of Silver Over Time
The below infographic from Blackrock Silver takes us on a journey of silver’s uses through time, from the past to the future.
3,000 BC – The Middle Ages
The earliest accounts of silver can be traced to 3,000 BC in modern-day Turkey, where its mining spurred trade in the ancient Aegean and Mediterranean seas. Traders and merchants would use hacksilver—rough-cut pieces of silver—as a medium of exchange for goods and services.
Around 1,200 BC, the Ancient Greeks began refining and minting silver coins from the rich deposits found in the mines of Laurion just outside Athens. By 100 BC, modern-day Spain became the center of silver mining for the Roman Empire while silver bullion traveled along the Asian spice trade routes. By the late 1400s, Spain brought its affinity for silver to the New World where it uncovered the largest deposits of silver in history in the dusty hills of Bolivia.
Besides the uses of silver in commerce, people also recognized silver’s ability to fight bacteria. For instance, wine and food containers were often made out of silver to prevent spoilage. In addition, during breakouts of the Bubonic plague in medieval and renaissance Europe, people ate and drank with silver utensils to protect themselves from disease.
The 1800s – 2000s
New medicinal uses of silver came to light in the 19th and 20th centuries. Surgeons stitched post-operative wounds with silver sutures to reduce inflammation. In the early 1900s, doctors prescribed silver nitrate eyedrops to prevent conjunctivitis in newborn babies. Furthermore, in the 1960s, NASA developed a water purifier that dispensed silver ions to kill bacteria and purify water on its spacecraft.
The Industrial Revolution drove the onset of silver’s industrial applications. Thanks to its high light sensitivity and reflectivity, it became a key ingredient in photographic films, windows, and mirrors. Even today, skyscraper windows are often coated with silver to reflect sunlight and keep interior spaces cool.
The 2000s – Present
The uses of silver have come a long way since hacksilver and utensils, evolving with time and technology.
Silver is the most electrically conductive metal, making it a natural choice for electronic devices. Almost every electronic device with a switch or button contains silver, from smartphones to electric vehicles. Solar panels also utilize silver as a conductive layer in photovoltaic cells to transport and store electricity efficiently.
In addition, it has several medicinal applications that range from treating burn wounds and ulcers to eliminating bacteria in air conditioning systems and clothes.
Silver for the Future
Silver has always been useful to industries and technologies due to its unique properties, from its antibacterial nature to high electrical conductivity. Today, silver is critical for the next generation of renewable energy technologies.
For every age, silver proves its value.
Visualizing 50 Years of Global Steel Production
Global steel production has tripled over the past 50 years, with China’s steel production eclipsing the rest of the world.
Visualizing 50 Years of Global Steel Production
From the bronze age to the iron age, metals have defined eras of human history. If our current era had to be defined similarly, it would undoubtedly be known as the steel age.
Steel is the foundation of our buildings, vehicles, and industries, with its rates of production and consumption often seen as markers for a nation’s development. Today, it is the world’s most commonly used metal and most recycled material, with 1,864 million metric tons of crude steel produced in 2020.
This infographic uses data from the World Steel Association to visualize 50 years of crude steel production, showcasing our world’s unrelenting creation of this essential material.
The State of Steel Production
Global steel production has more than tripled over the past 50 years, despite nations like the U.S. and Russia scaling down their domestic production and relying more on imports. Meanwhile, China and India have consistently grown their production to become the top two steel producing nations.
Below are the world’s current top crude steel producing nations by 2020 production.
|Rank||Country||Steel Production (2020, Mt)|
|#5||🇺🇸 United States||72.7|
|#6||🇰🇷 South Korea||67.1|

Despite its current dominance, China could be preparing to scale back domestic steel production to curb overproduction risks and ensure it can reach carbon neutrality by 2060.
As iron ore and steel prices have skyrocketed in the last year, U.S. demand could soon lessen depending on the Biden administration’s actions. A potential infrastructure bill would bring investment into America’s steel mills to build supply for the future, and any walkbalk on the Trump administration’s 2018 tariffs on imported steel could further soften supply constraints.
Steel’s Secret: Infinite Recyclability
Made up primarily of iron ore, steel is an alloy which also contains less than 2% carbon and 1% manganese and other trace elements. While the defining difference might seem small, steel can be 1,000x stronger than iron.
However, steel’s true strength lies in its infinite recyclability with no loss of quality. No matter the grade or application, steel can always be recycled, with new steel products containing 30% recycled steel on average.
The alloy’s magnetic properties make it easy to recover from waste streams, and nearly 100% of the steel industry’s co-products can be used in other manufacturing or electricity generation.
It’s fitting then that steel makes up essential parts of various sustainable energy technologies:
- The average wind turbine is made of 80% steel on average (140 metric tons).
- Steel is used in the base, pumps, tanks, and heat exchangers of solar power installations.
- Electrical steel is at the heart of the generators and motors of electric and hybrid vehicles.
The Steel Industry’s Future Sustainability
Considering the crucial role steel plays in just about every industry, it’s no wonder that prices are surging to record highs. However, steel producers are thinking about long-term sustainability, and are working to make fossil-fuel-free steel a reality by completely removing coal from the metallurgical process.
While the industry has already cut down the average energy intensity per metric ton produced from 50 gigajoules to 20 gigajoules since the 1960s, steel-producing giants like ArcelorMittal are going further and laying out their plans for carbon-neutral steel production by 2050.
Steel consumption and demand is only set to continue rising as the world’s economy gradually reopens, especially as Rio Tinto’s new development of atomized steel powder could bring about the next evolution in 3D printing.
As the industry continues to innovate in both sustainability and usability, steel will continue to be a vital material across industries that we can infinitely recycle and rely on.
