While copper prices are hitting all-time highs, there is a metal that you rarely hear about recently creeping into headlines. It is tungsten – a metal that is the backbone of a country’s industrial base. A smaller, less covered, and more aggressive idea in the space is American Tungsten Corp. (TUNGF), writes Carl Delfeld, editor of Cabot Explorer.
Tungsten is arguably the strongest, toughest, hardest metal. It has the highest melting point and highest boiling point of all the elements. Pure tungsten is silver colored, offers high density, and resists fracture even in high temperatures.
American Tungsten Corp. (TUNGF)

A mix of steel and tungsten was first demonstrated at the 1900 World Exhibition in Paris. It’s at the core of machining with myriad applications in our modern economy, including advanced weapons platforms, aerospace engineering, semiconductor manufacturing, and high-performance industrial tooling.
American Tungsten is developing an Idaho mine that was in operation from the early 1900s and mined and processed approximately 722,400 tons of mineralized material prior to its closing in 1958. Now it’s re-opening.
The company was listed in late 2024 and is in the stage of determining what potential the mine has in terms of potential proven reserves. The company’s market value is just under $100 million and the stock is down from its high but in an uptrend.
The company is on schedule to restart strategy at the high-grade IMA Mine in Idaho. Because the United States currently has zero active tungsten mines, this presents a speculative opportunity for aggressive investors.
