American Tungsten Advances Metallurgical and Infrastructure Studies at the IMA Mine
American Tungsten advances its IMA Mine restart strategy through ongoing metallurgical and geotechnical studies.
American Tungsten Corp. announced the launch of a comprehensive metallurgical testing program led by Bomenco Minerals Engineering Corp. and SGS Laboratories to develop viable tungsten recovery processes for the Ima Mine. The Company has also commenced geotechnical investigations by NewFields MTDs to support the design of the Mine's tailings and waste rock storage facilities. These programs are critical technical milestones intended to reduce technical risk and support the Company's phased strategy of processing existing surface tailings and restarting historical underground operations. Historical production at the Ima Mine was approximately 199,449 MTUs of WO3 between 1945 and 1957.
American Tungsten Corp (TUNG) announced a development milestone at its Ima Mine project that represents a logical progression in technical de-risking. The update follows a series of routine positive developments, including a $40M bought-deal financing in March 2026, successful underground drilling on the D-Level and Zero-Level, and initial metallurgical test results in March 2026 showing high tungsten recoveries via gravity concentration.
The market had already priced in the necessity for these engineering and metallurgical studies as part of the path to a Preliminary Economic Assessment (PEA) or Feasibility Study. The news is incremental and routine, confirming that the company is executing its development plan on schedule without introducing new, unexpected catalysts or material changes to the project's economics.
American Tungsten Corp. (TUNG) is a pre-revenue exploration and development-stage company focused on the Ima Mine project in Lemhi County, Idaho, USA. The Ima Mine is a historic underground tungsten producer that operated from 1945 to 1957, producing approximately 199,449 MTUs of WO3.
The company’s strategy is two-phased: Phase I focuses on evaluating and potentially processing existing surface tailings as a lower-capital pathway to near-term production, while Phase II targets the rehabilitation and restart of the historic underground mine. American Tungsten Corp. holds an exclusive option to acquire full ownership of the property, subject to a 2% royalty, and has expanded its land position with 113 additional federal claims covering nearly 2,000 acres.
