Core Viewpoint - United States Antimony Corporation (USAC) has raised its fiscal 2026 revenue guidance by 25% due to successful mining activities at the Stibnite Hill antimony mine in Montana, indicating a significant operational breakthrough for the company [1][10]. Operational Updates - USAC has commenced exploration and bulk sampling at the Stibnite Hill mine, which previously operated from the late 1960s to early 80s, following state approval [1]. - The material mined from Stibnite Hill has high enough grades for profitable operations without extensive lead times or large capital investments [2]. - Over 250 tonnes of antimony ore have been transported to a flotation mill for processing, with preliminary tests suggesting the material can meet military specifications [3]. - USAC is currently the only North American company approved as a sole-source supplier of antimony trisulphide to the Defense Logistics Agency [4]. Financial Performance - The company anticipates profit margins from mining its own antimony material to be approximately three times greater than purchasing from third parties [5]. - USAC has increased its revenue guidance by $25 million to a total of $125 million for the fiscal year 2026 [10]. Production Capacity - The Thompson Falls smelter can produce approximately 15 million pounds of antimony oxide or 5 million pounds of antimony metal annually, with an expansion underway to increase production capacity [7]. - The company plans to have new furnaces operational by January 2026, enhancing its production capabilities [8]. Strategic Moves - USAC has decided not to pursue further discussions regarding its proposed takeover of Larvotto Resources after its offer was rejected, citing increased antimony supply as a key factor [11]. - The integration of Larvotto's future production with USAC's established smelting capabilities is viewed as a strategic move to strengthen the supply chain for critical minerals in the Western world [12].
