Mithril Mining Corp is advancing the Calvert Tungsten Mine, one of the highest-grade historical #tungsten resources in the U.S. As America remains reliant on foreign critical minerals, we’re focused on rebuilding domestic tungsten production and supply chain independence #Mining

The 2027 DFARS #tungsten procurement restrictions are approaching.
As the U.S. #defense supply chain moves away from foreign-sourced tungsten, demand for secure domestic supply will become increasingly important.
American tungsten development matters.

Tungsten is a critical input for defense systems, aerospace components, and industrial tooling. A stronger domestic tungsten supply chain means greater manufacturing resilience and national security. #Tungsten #CriticalMinerals #Mining

Reshoring American critical mineral production one claim at a time.
Mar 22
This is Taylor Sulik (@TheTungstenGuy).
He's a former US Coast Guard member turned mining entrepreneur and founder of Mithril Mining (@Mithril_Mining).
What started as an intense passion in 2023 is now a full-fledged project generator business model with Strategic Tungsten Assets under ownership.
Taylor isn't using Claude to make fancy calendar productivity apps.
He's building a US tungsten company to provide the much-needed metal to the Department of War.
And he almost died this weekend doing it, getting stuck in 3 feet of snow staking claims in Idaho; rescued by the Sheriff's Department.
This is American Entrepreneurship at its finest.
I joined Mithril because I believe in Taylor and his mission to resurrect American Tungsten Production.
Taylor is doing a very hard thing (building a mining company from scratch).
But he's doing it.
And his story is worth following.

America cannot rebuild its industrial base without rebuilding its mines.
Today, we launched the our website, highlighting our work to advance domestic tungsten production, beginning with the Calvert Tungsten Mine - a strategic, past-producing asset.

The Calvert Mine benefits from:
• Established access
• Proximity to historic processing routes
• A stable, mining-supportive U.S. jurisdiction
These factors significantly reduce redevelopment risk relative to greenfield exploration.

Tungsten continues it's rapid price increase as we head into 2026 - up over 100% since January of this year.
With no short-term Western supply coming online, Mithril Mining is uniquely positioned to take advantage of this opportunity to reshore American Tungsten production!

China has tightened Tungsten export restrictions
This is why reshoring of critical mineral production matters. Tungsten isn't just a metal - its necessary for industrial strength
No nation should depend on its strategic competitor for critical minerals
