AMERICAN TUNGSTEN CORP. BEGINS TRADING ON OTCQX BEST MARKET

American Tungsten Corp. has upgraded to OTCQX from the OTCQB Venture Market.

American Tungsten begins trading today on OTCQX under the symbol TUNGF.

American Tungsten is focused on advancing its high-grade flagship asset, the Ima mine in Lemhi county, Idaho. The Ima mine is a past-producing tungsten property with a proven history of significant production. As demand for critical minerals continues to grow, the company is advancing a strategically located asset with the potential to play an important role in strengthening North American supply chains.

The OTCQX Market is designed for established, investor-focused United States and international companies. To qualify for OTCQX, companies must meet high financial standards, follow best practice corporate governance and demonstrate compliance with applicable securities laws. Graduating to the OTCQX Market from the OTCQB Market marks an important milestone for companies, enabling them to demonstrate their qualifications and build visibility among U.S. investors.

"This advancement to OTCQX enhances our visibility within the investment community, broadens access for U.S. investors, and reflects our commitment to the high standards of transparency and governance expected by the market. As demand for secure domestic sources of critical minerals continues to grow, we believe American Tungsten is well positioned to create long-term value for shareholders," said Ali Haji, chief executive officer of American Tungsten.

Trading in non-U.S. North American securities on OTC Markets reached $23.4-billion in the second quarter of 2026, representing an 88.25-per-cent increase over Q2 2025. OTC Markets recorded $453.34-billion in total dollar volume in the first half of the year. Canada ranked among the top home markets by trading volume during the quarter, highlighting sustained U.S. investor demand for internationally listed names.
