Zinc concentrate benchmark TC lowest since 2006 on tight
Zinc concentrate benchmark TC lowest since 2006 on tight supply. In China, the average TCs for imported spot zinc concentrated dipped to an all time low at $12.5/mt in January this year, and only edged up to $20/mt as of May 1, SMM data showed. In February, LME zinc prices soared to $3,595.5/mt, a record high since July 2007. Such high zinc prices are likely to drive restarts across mines.
