American Tungsten Corp. (TSXV: TUNG | OTCQX: TUNGF | FSE: RK90) has established a substantially larger resource base at its past producing IMA Mine in Idaho. In a new InvestorNews interview with host Tracy Hughes, CEO and Director Ali Haji discussed the company’s newly announced mineral resource estimate, its plan to produce tungsten concentrate from historical tailings and the economic assumptions that will be tested in an upcoming Preliminary Economic Assessment.The mineral resource estimate includes 316,000 tonnes of indicated resources grading 0.55% tungsten trioxide, or WO₃, and 2.178 million tonnes of inferred resources grading 0.55% WO₃. Together, the underground resource contains approximately 13,680 tonnes of WO₃ and more than 2.25 million ounces of silver. A separate surface tailings resource contains 267,000 indicated tonnes grading 0.155% WO₃, with 413 tonnes of contained WO₃ and 79,000 ounces of silver.“When we started the company, the vision was to ensure that we had a seven to ten year mine life,” Haji said. He noted that the approximately 2.5 million tonne underground resource is more than eight times the roughly 300,000 tonnes contained in the historical estimate upon which the company began its work. The new estimate has an effective date of July 15, 2026, was prepared independently by Minetech, LLC and incorporates more than 17,000 feet of drilling completed by American Tungsten since December 2025.For Haji, the defining feature is the underground resource grade. The estimate was reported using a 0.20% WO₃ cut off based on a tungsten price of US$1,300 per metric tonne unit, total site operating costs of US$165 per tonne, 80% recovery and 80% payability. Silver and molybdenum occur alongside the tungsten and could provide valuable byproduct credits, although their economic contribution will need to be established through the company’s technical studies.“Grade is king,” Haji told InvestorNews. “Our head grade at 0.55% would be deemed the highest new resource announced in the United States.” He added that the proposed cut and fill underground mining method should allow American Tungsten to selectively mine the vein system while limiting the amount of waste entering the processing circuit.American Tungsten’s proposed first step toward production is the processing of the historical tailings already situated at IMA. Haji said metallurgical testing is underway and results are expected by the end of September. Subject to successful testing, engineering and commissioning, the company is targeting its first concentrate sale before Christmas 2026.“The tailings are homogeneous in nature and shovel ready, allowing us to bring production online quite quickly,” Haji said. Management estimates that the tailings could potentially generate between US$45 million and US$75 million in revenue over approximately two years, with relatively low mining costs because the material would not require conventional drilling or blasting. These projections remain forward looking, and the mineral resource estimate cautions that mineral resources are not mineral reserves and do not yet have demonstrated economic viability.To read the full column, go to: https://bit.ly/4ctbQOcDisclaimer: Video interviews and other video content published by InvestorNews are produced as part of paid media services.
