PMET Resources is trading 5.1% down at CA$4.28, consistent with broader materials-sector pressure and macroeconomic headwinds. - The supplied materials-sector context showed the sector down 1.55%, alongside falling U.S. indices and rising oil prices and Treasury yields. - No September 28 company announcement was listed. The latest listed news was September 22, about completing Phase 2 caesium testwork with Koch Technology Solutions; macroeconomic headwinds offer a more plausible explanation than a new company-specific catalyst.
