Guardian Metal Resources PLC ADS (GMTL)

Guardian Metal Resources plc is a mineral exploration and development company focused on tungsten in the United States. The company is based in the United Kingdom, where its shares are traded in London, and its American Depositary Shares are listed on NYSE American.

Its principal assets are located in Nevada and include the Pilot Mountain project and the Garfield Flats project, both of which contain tungsten mineralization that the company is working to define and advance. Guardian Metal's strategy is built around establishing a domestic U.S. supply of tungsten, a critical metal used in defense applications, cutting tools, electronics and industrial alloys, at a time when global supply is heavily concentrated outside North America.

The company's work includes drilling, resource estimation and metallurgical studies aimed at moving its projects toward potential production.
