Imported ore market. With the Labour Day holiday approaching, fewer offers were made by traders this week. Overall, by-product-rich ore offers were heard at around -$40 to -$50/dmt, and the market was sluggish, with imported zinc concentrate TCs remaining at low levels.
This week, SMM zinc concentrate inventory at China's main ports totaled 284,000 mt in physical content, up 5,000 mt in physical content WoW, with Qinzhou port inventories contributing the main increase.
