Operational milestone advances Calvert material toward downstream evaluation and supports Mithril’s strategy to strengthen the U.S. tungsten supply chain
July 16, 2026
BEAVERHEAD COUNTY, MONTANA — Mithril Mining Corp. (“Mithril” or the “Company”) announces the completion of a 500-ton bulk sample removal of historical surface material from the Calvert Tungsten Mine in Beaverhead County, Montana.
The completion represents a significant operational milestone for Mithril and advances the Company’s strategy to evaluate a potential domestic pathway connecting American tungsten resources with U.S. processing and manufacturing.
Some of the material will be transported to Tungsten Parts Wyoming, a U.S.-based tungsten manufacturer serving defense, aerospace, and industrial markets, for evaluation. As previously announced, Mithril and Tungsten Parts Wyoming entered a Letter of Intent establishing a framework to evaluate tungsten concentrate derived from Calvert material and determine its suitability for future domestic manufacturing applications. With the 500-ton bulk sample now completed, Mithril is moving from material recovery into the next phase of technical and downstream evaluation.
“Completing this 500-ton bulk sample is a significant milestone for Mithril and another step forward in developing the Calvert Tungsten Mine,” said Taylor Sulik, CEO of Mithril Mining Corp. “We recovered the material, completed the work, and are now entering downstream evaluation with an American tungsten manufacturer. Each step is designed to generate the technical data and commercial understanding required to build a credible domestic tungsten supply chain.”
Mithril believes the completion of the bulk sample demonstrates the Company’s ability to deliver on defined objectives through disciplined execution, strategic partnerships, and a clear focus on building long-term value. Mithril’s strategy is centered on recovering American material, testing it, verifying the results, and connecting viable domestic resources with U.S. manufacturers to support American defense applications.
Calvert is recognized as one of the highest-grade historic tungsten deposits in the United States. Mithril’s current work is focused on generating the technical, metallurgical, and commercial data required to evaluate the material and determine potential pathways toward domestic processing and manufacturing.
The 500-ton bulk sample will support further assay, processing, metallurgical, and manufacturing suitability evaluation. Results from this work will help inform future technical and commercial decisions as Mithril continues to advance its evaluation of the Calvert Tungsten Mine.
“Domestic supply chains are built through execution,” added Sulik. “Material has to be recovered. Data has to be generated. Metallurgy has to be understood. Manufacturing suitability has to be verified. Completing this bulk sample moves Calvert into that next stage of evaluation and moves Mithril another step forward in our mission.”
Mithril Mining remains focused on disciplined project advancement, responsible stewardship, and developing the technical and commercial relationships necessary to help rebuild America’s domestic tungsten supply chain.
