The History of Tungsten
With a tensile strength of 1,510 megapascals, we now know tungsten as the strongest naturally occurring metal on Earth.
Today’s infographic is from Almonty Industries, a tungsten producer, and it reveals the history of tungsten.
Interestingly, the infographic shows that despite tungsten’s strength, most of civilization has lived without any practical use of the metal. That’s because tungsten wasn’t officially discovered until the 18th century – though, as you will see, it was a thorn in the side of metallurgists for many centuries before that.
From the Heavens
Like all elements with an atomic number higher than iron, tungsten cannot be created by nuclear fusion in stars like our sun.
Instead, tungsten is thought to be formed from the explosions of massive stars. Each supernova explosion has so much energy, that these newly created elements are jettisoned at incredible speeds of 30,000 km/s, or 10% of the speed of light – and that’s how they get dispersed throughout the universe.
Supernova explosions don’t happen often – as a result, in every 1,000,000 grams of the Earth’s crust, there are only 1.25 grams of tungsten.
An Unusual History
In the periodic table, tungsten is listed under the letter “W”. That’s because two names for the same metal actually arose simultaneously.
WOLFRAM: derived from the German words WOLF (English: wolf) and the Middle High German word RAM (English: dirt).
In the Middle Ages, tin miners in Germany complained about a mineral (wolframite) that accompanied tin ore and reduced tin yields when smelting.
With a longish, hair-like appearance, wolframite was thought to be a “wolf” that ate up the tin. Wolframite had plagued metallurgists for many centuries, until tungsten was discovered and proper methods were developed to deal with the heavy metal.
TUNGSTEN: derived from the Swedish words TUNG (English: heavy) and STEN (English: stone) due to its density
Scheelite, the other important tungsten ore, was discovered in an iron mine in Sweden in 1750.
It garnered interest for its incredible density – which is why it was named “heavy stone”.
The metal was discovered by Spanish nobleman Juan José D´Elhuyar, who eventually synthesized tungsten from both wolframite and scheelite – showing they were both minerals from the same new element.
History of Tungsten Uses
Discoveries in tungsten use can be loosely linked to four fields: chemicals, steel and super alloys, filaments, and carbides.
1847: Tungsten salts are used to make colored cotton and to make clothes used for theatrical and other purposes fireproof.
1855: The Bessemer process is invented, allowing for the mass production of steel. At the same time, the first tungsten steels are being made in Austria.
1895: Thomas Edison investigated materials’ ability to fluoresce when exposed to X-rays, and found that calcium tungstate was the most effective substance.
1900: High Speed Steel, a special mix of steel and tungsten, is exhibited at the World Exhibition in Paris. It maintains its hardness at high temperatures, perfect for use in tools and machining.
1903: Filaments in lamps and lightbulbs were the first use of tungsten that made use of its extremely high melting point and its electrical conductivity. The only problem? Early attempts found tungsten to be too brittle for widespread use.
1909: William Coolidge and his team at General Electric the U.S. are successful in discovering a process that creates ductile tungsten filaments through suitable heat treatment and mechanical working.
1911: The Coolidge Process is commercialized, and in a short time tungsten light bulbs spread all over the world equipped with ductile tungsten wires.
1913: A shortage in industrial diamonds in Germany during WWII leads researchers to look for an alternative to diamond dies, which are used to draw wire.
1914: “It was the belief of some Allied military experts that in six months Germany would be exhausted of ammunition. The Allies soon discovered that Germany was increasing her manufacture of munitions and for a time had exceeded the output of the Allies. The change was in part due to her use of tungsten high-speed steel and tungsten cutting tools. To the bitter amazement of the British, the tungsten so used, it was later discovered, came largely from their Cornish Mines in Cornwall.” – From K.C. Li’s 1947 book “TUNGSTEN”
1923: A German electrical bulb company submits a patent for tungsten carbide, or hardmetal. It’s made by “cementing” very hard tungsten monocarbide (WC) grains in a binder matrix of tough cobalt metal by liquid phase sintering.
The result changed the history of tungsten: a material which combines high strength, toughness and high hardness. In fact, tungsten carbide is so hard, the only natural material that can scratch it is a diamond. (Carbide is the most important use for tungsten today.)
1930s: New applications arose for tungsten compounds in the oil industry for the hydrotreating of crude oils.
1940: The development of iron, nickel, and cobalt-based superalloys begin, to fill the need for a material that can withstand the incredible temperatures of jet engines.
1942: During World War II, the Germans were the first to use tungsten carbide core in high velocity armor piercing projectiles. British tanks virtually “melted” when hit by these tungsten carbide projectiles.
1945: Annual sales of incandescent lamps are 795 million per year in the U.S.
1950s: By this time, tungsten is being added into superalloys to improve their performance.
1960s: New catalysts were born containing tungsten compounds to treat exhaust gases in the oil industry.
1964: Improvements in efficiency and production of incandescent lamps reduce the cost of providing a given quantity of light by a factor of thirty, compared with the cost at introduction of Edison’s lighting system.
2000: At this point, about 20 billion meters of lamp wire are drawn each year, a length which corresponds to about 50 times the earth-moon distance. Lighting consumes 4% and 5% of the total tungsten production.
Today, tungsten carbide is extremely widespread, and its applications include metal cutting, machining of wood, plastics, composites, and soft ceramics, chipless forming (hot and cold), mining, construction, rock drilling, structural parts, wear parts and military components.
Tungsten steel alloys are also used the in the production of rocket engine nozzles, which must have good heat resistant properties. Super-alloys containing tungsten are used in turbine blades and wear-resistant parts and coatings.
However, at the same time, the reign of the incandescent lightbulb has come to an end after 132 years, as they start to get phased out in the U.S. and Canada.
How to Avoid Common Mistakes With Mining Stocks (Part 5: Funding Strength)
A mining company’s past projects and funding strength are interlinked. This infographic outlines how a company’s ability to raise capital can determine the fate of a mining stock.
A mining company’s past projects and funding strength are interlinked, and can provide clues as to its potential success.
A good track record can provide better opportunities to raise capital, but the company must still ensure it times its financing with the market, protects its shareholders, and demonstrates value creation from the funding it receives.
Part 5: The Role of Funding Strength
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.
Part 5 of the series highlights six things to keep in mind when analyzing a company’s project history and funding ability.
View all five parts of the series:
- 1. Common mistakes made with the team
- 2. Common mistakes made with the business plan
- 3. Common mistakes with the jurisdiction of the project
- 4. Common mistakes with the project and technical risks
- 5. Common mistakes with raising money
Part 5: Raising Capital and Funding Strength
So what must investors evaluate when it comes to funding strength?
Here are six important areas to cover.
1. Past Project Success: Veteran vs. Recruit
A history of success in mining helps to attract capital from knowledgeable investors. Having an experienced team provides confidence and opens up opportunities to raise additional capital on more favorable terms.
- A team with past experience and success in similar projects
- A history of past projects creating value for shareholders
- A clear understanding of the building blocks of a successful project
A company with successful past projects instills confidence in investors and indicates the company knows how to make future projects successful, as well.
2. Well-balanced Financing: Shareholder Friendly vs. Banker Friendly
Companies need to balance between large investors and protecting retail shareholders. Management with skin in the game ensures they find a balance between serving the interests of both of these unique groups.
- Clear communication with shareholders regarding the company’s financing plans
- High levels of insider ownership ensures management has faith in the company’s direction, and is less likely to make decisions which hurt shareholders
- Share dilution is done in a limited capacity and only when it helps finance new projects that will create more value for shareholders
Mining companies need to find a balance between keeping their current shareholders happy while also offering attractive financing options to attract further investors.
3. A Liquid Stock: Hot Spot vs. Ghost Town
Lack of liquidity in a stock can be a major problem when it comes to attracting investment. It can limit investments from bigger players like funds and savvy investors. Investors prefer liquid stocks that are easily traded, as this allows them to capitalize on market trends.
- A liquid stock ensures shareholders are able to buy and sell shares at their expected price
- More liquid stocks often trade at better valuations than their illiquid counterparts
- High liquidity can help avoid price crashes during times of market instability
Liquidity makes all the difference when it comes to attracting investors and ensuring they’re comfortable holding a company’s stock.
4. Timing the Market: On Time vs. Too Late or Too Early
Raising capital at the wrong time can result in little interest from investors. Companies in tune with market cycles can raise capital to capture rising interest in the commodity they’re mining.
Being On Time:
- Raising capital near the start of a commodity’s bull market can attract interest from speculators looking to capitalize on price trends
- If timed well, the attention around a commodity can attract investors
- Well-timed financing will instill confidence in shareholders, who will be more likely to hold onto their stock
- Raising capital at the right time during bull markets is less expensive for the company and reduces risk for investors
Companies need to time when they raise capital in order to maximize the amount raised.
5. Where is the Money Going? Money Well Spent vs. Well Wasted
How a company spends its money plays a crucial role in whether the company is generating more value or just keeping the lights on. Investors should always try to determine if management is simply in it for a quick buck, or if they truly believe in their projects and the quality of the ore the company is mining.
Money Well Spent:
- Raised capital goes towards expanding projects and operations
- Efficient use of capital can increase revenue and keep shareholders happy with dividend hikes and share buybacks
- By showing tangible results from previous investments, a company can more easily raise capital in the future
Raised capital needs to be allocated wisely in order to support projects and generate value for shareholders.
6. Additional Capital: Back for More vs. Tapped Out
Mining is a capital intensive process, and unless the company has access to a treasure trove, funding is crucial to advancing any project. Companies that demonstrate consistency in their ability to create value at every stage will find it easier to raise capital when it’s necessary.
Back For More:
- Raise more capital when necessary to fund further development on a project
- Able to show the value they generated from previous funding when looking to raise capital a second time
- Attract future shareholders easily by treating current shareholders well
Every mining project requires numerous financings. However, if management proves they spend capital in a way that creates value, investors will likely offer more funding during difficult or unexpected times.
Wealth Creation and Funding Strength
Mining companies that develop significant assets can create massive amounts of wealth, but often the company will not see cash flow for years. This is why it is so important to have funding strength: an ability to raise capital and build value to harvest later.
It is a challenging process to build a mining company, but management that has the ability to treat their shareholders and raise money can see their dreams built.
How the World’s Top Gold Mining Stocks Performed in 2020
The GDX is an ETF that tracks the performance of the top gold mining stocks. How did the GDX and its constituents perform in 2020?
How Top Gold Mining Stocks Performed in 2020
Gold mining stocks and the GDX saw strong returns in 2020 as gold was one of the most resilient and best performing assets in a highly volatile year.
But picking gold mining stocks isn’t easy, as each company has a variety of individual projects and risks worth assessing. This is why the GDX (VanEck Vectors Gold Miners ETF), is one of the most popular methods investors choose to get exposure to players in the gold mining industry.
While the GDX and gold miners can generally offer leveraged upside compared to gold during bull markets, in 2020 the GDX returned 23%, just a couple of points shy from spot gold’s 25.1% return.
This graphic compares the returns of gold, the GDX, and the best and worst performing gold mining equities in the index.
Understanding the GDX ETF and its Value
The GDX is one of many index ETFs created by investment management firm VanEck and offers exposure to 52 of the top gold mining stocks.
It provides a straightforward way to invest in the largest names in the gold mining industry, while cutting down on some of the individual risks that many mining companies are exposed to. The GDX is VanEck’s largest and most popular ETF averaging ~$25M in volume every day, with the largest amount of total net assets at $15.3B.
In terms of its holdings, the GDX attempts to replicate the returns of the NYSE Arca Gold Miners Index (GDM), which tracks the overall performance of companies in the gold mining industry.
How the Largest Gold Miners Performed in 2020
As a market-cap weighted ETF, the GDX allocates more assets towards constituents with a higher market cap, resulting in larger gold mining companies making up more of the index’s holdings.
This results in the five largest companies in the GDX making up 39.5% of the index’s holdings, and the top 10 making up 59.3%.
An equally-weighted index of the top five GDX constituents returned 27.3% for the year, outperforming gold and the index by a few points. Meanwhile, an equally-weighted index of the top 10 constituents significantly underperformed, only returning 18.4%.
Newmont was the only company of the top five which outperformed gold and the overall index, returning 37.8% for the year. Wheaton Precious Metals (40.3%) and Kinross Gold (54.9%) were the only other companies in the top 10 that managed to outperform.
Kinross Gold was the best performer among the top constituents largely due to its strong Q3 results, where the company generated significant free cash flow while quadrupling reported net earnings. Along with these positive results, the company also announced its expectation to increase gold production by 20% over the next three years.
The Best and Worst Performers in 2020
Among the best and worst performers of the GDX, it was the smaller-sized companies in the bottom half of the ranking which either significantly over- or underperformed.
K92 Mining’s record gold production from their Kainantu gold mine, along with a significant resource increase at their high-grade Kora deposit nearby saw a return of 164.2%, with the company graduating from the TSX-V to the TSX at the end of 2020.
Four of the five worst performers for 2020 were Australian mining companies as the country entered its first recession in 30 years after severe COVID-19 lockdowns and restrictions. Bushfires early in the year disrupted shipments from Newcrest’s Cadia mine, and rising tensions with China (Australia’s largest trading partner) also contributed to double-digit drawdowns for some Australian gold miners.
The worst performer and last-ranked company in the index, Resolute Mining (-36.9%), had further disruptions in H2’2020 at their Syama gold mine in Mali. The military coup and resignation of Mali’s president Ibrahim Keïta in August was followed by unionized workers threatening strikes in September, slowing operations at Syama gold mine. Outright strikes eventually occurred before year’s end.
How Gold Mining Stocks are Chosen for the GDX
There are some ground rules which dictate how the index is weighted to ensure the GDM and GDX properly reflect the gold mining industry.
Along with the rules on the index’s weighting, there are company-specific requirements for inclusion into the GDM, and as a result the GDX:
- Derive >50% of revenues from gold mining and related activities
- Market capitalization >$750M
- Average daily volume >50,000 shares over the past three months
- Average daily value traded >$1M over the past three months
Gold mining stocks already in the index have some leeway regarding these requirements, and ultimately inclusion or exclusion from the index us up to the Index Administrator.
What 2021 Will Bring for Gold Mining Stocks
The GDX has had a muted start to the new year, with the index at -2.3% as it has mostly followed spot gold’s price.
Gold and gold mining stocks cooled off significantly following their strong rally Q1-Q3’2020, as positive developments regarding the COVID-19 vaccine have resulted in a stronger-than-expected U.S. dollar and a rise in treasury yields.
This being said, the arrival of new monetary stimulus in the U.S. could spur inflation-fearing investors towards gold and gold mining stocks as the year progresses.
