On June 3, United States Antimony Corp fell 8.1% in regular trading, trading at $9.3507/share, with trading volume of $33.75 million. The stock had surged as high as $10.23 earlier in the session before reversing sharply.

The decline was triggered by a confluence of negative factors. On June 2, the company filed a Form 144 report disclosing a proposed sale of securities by an insider, raising concerns about potential dilution and signaling reduced confidence from those closest to the business. This followed a pattern of multiple Form 144 filings in recent months.

Adding to the pressure, the Diversified Metals and Mining sector experienced a broad-based selloff. Among sector peers, USA Rare Earth Inc. fell 7.79%, Teck Resources Ltd declined 4.35%, MP Materials Corp. dropped 4.30%, HudBay Minerals lost 3.70%, and Rio Tinto PLC slipped 2.57%, amplifying the downside momentum for individual names.

United States Antimony Corporation, founded in 1968 and headquartered in Montana, operates antimony mining and processing facilities. Its Montana antimony processing plant expansion is nearing completion, expected to more than triple production capacity.
