U.S.-listed shares of miners producing critical minerals fell between ⁠3% ‌and 8% in premarket trading on Thursday. Kroon and Robertson told the meeting that Washington is no longer in a position to offer price floors, according to the sources. None were offered price floors, sparking questions about the government's commitment to that financial tool. U.S. mining and processing companies have pushed for price floors and other government backstops to help them compete with China. Other countries, including Australia, have also considered price floors for critical minerals.
