American Tungsten Reports Positive Initial Metallurgical Test Work Results From IMA Tungsten Project

Core Viewpoint - American Tungsten Corp. has reported positive initial metallurgical test results from the IMA Mine, indicating the potential for efficient processing pathways for tungsten-silver mineralized samples [1][2]. Group 1: Test Program and Results - Sepro Laboratories conducted gravity and flotation tests on 130 kgs of tungsten quartz vein material from the IMA Mine, revealing average grades of 1.1% WO3, 83 ppm Ag, 0.09% Cu, 0.037% Mo, and 0.41% S [3][4]. - The test program aimed to evaluate the amenability of the mineralized materials to a gravity-flotation flowsheet, including methods such as dense media separation and Falcon centrifugal gravity concentration [4]. - Initial gravity tests achieved 84.4% WO3 recovery at a 29.6% mass pull, with potential for over 90% recovery through gravity methods [6][19]. - Heavy liquid separation tests demonstrated a 91.1% overall WO3 recovery at a 33.8% mass pull, indicating strong potential for DMS as a pre-concentration method [7][19]. - Sulfide-tungsten flotation testing recovered 81.4% of S, 83.2% of Cu, 72.0% of Ag, and 59.1% of Mo with minimal WO3 loss [8][19]. Group 2: Company Position and Future Plans - The company completed a $40 million bought deal financing, positioning itself to accelerate technical de-risking and advance development activities for the IMA Tungsten Project [2]. - American Tungsten is actively interpreting test results and planning further metallurgical and process design testing, including variability tests and additional flotation methods [10]. - The IMA Mine is a historically significant underground tungsten mine that produced approximately 199,449 MTUs of WO3 between 1945 and 1957, and the company is assessing the potential for re-starting mining operations [11][17].
