About IMA Mine Project
These historical resource estimates pre-date the implementation of NI 43-101 and do not use categories stipulated by CIM. Prior operators assigned confidence categories which differ from those stipulated by CIM, as they may not have demonstrated economic viability. The estimates should not be relied upon until they have been verified. Neither American Tungsten, nor its Qualified Person, has not done sufficient work to classify the historical estimates as current mineral resources. American Tungsten is not treating the historical estimates as current mineral resources or mineral reserves. The historical estimates are relevant as they demonstrate the tenor and size of exploration targets that exist on the property. Additional work, including drilling, validation sampling, and assessment of reasonable prospects for economic viability, would be required to upgrade or verify the historical estimates as current mineral resources.

Drill resultsAmerican Tungsten Advances Resource Expansion Drilling, Confirms Over 900 Feet of Strike Length on the No. 5 and No. 7 Veins, and Highlights Broader Development Potential at the IMA Mine
Results from six additional drill holes at the past-producing Ima Mine in Idaho confirm tungsten-silver mineralization in the No. 5 and No. 7 veins over more than 900 feet of strike length, with the main Ima vein system extended over 800 vertical feet down dip. Intercepts include 16 ft grading 1.20% WO₃ and 2.99 oz/t Ag in hole AT26-38, and 36.8 ft grading 0.78% WO₃ and 1.37 oz/t Ag in AT26-34. Ov
Drill resultsAmerican Tungsten Advances Metallurgical and Infrastructure Studies at the IMA Mine
A metallurgical testing program at the past-producing Ima Mine in East Central Idaho has been launched under Bomenco Minerals Engineering Corp., with testing coordinated through SGS Laboratories, to develop tungsten recovery processes and data for future engineering and economic evaluations. NewFields MTDs has also been retained for geotechnical investigations supporting design of the proposed Tai
Study resultsAmerican Tungsten Ramps-up Exploration Operations; Initiates 35,000 ft Surface and Underground Drilling Program at Ima Mine
A 35,000-foot drilling program comprising 33 underground holes and 20 surface holes has begun at the Ima Mine property in Lemhi County, Idaho, with two surface rigs and two underground rigs on site. A new crosscut is being developed on the D level to establish underground drill stations. Rockhead Consulting LLC has mobilized two track-mounted surface core rigs, one operating and the second to star
