(MB) Base metal prices on the Shanghai Futures Exchange were all up during Asian morning trading on Thursday, finding support from the release of positive Chinese data and a weaker dollar. China’s manufacturing Purchasing Managers’ Index (PMI) for May surprised to the upside with a reading of 51.9, surpassing an expected print of 51.4, according to data from China’s National Bureau of Statistics. Meanwhile, China’s services PMI for May was broadly in line with expectations, narrowly beating an expected print of 54.8 with a reading of 54.9. Shipments of value-added products by US and Canadian aluminium producers experienced a substantial jump in April following the imposition of sanctions last month against Russian supplier UC Rusal plc. Zinc concentrate treatment charges (TCs) rose to their highest level this year in May, with smelters refraining from purchases of spot tonnages. And the upward trend in lead concentrate TCs reversed after an import arbitrage opened up in China. South32 has agreed to buy a 50% stake in Australian metallurgical coal project Eagle Downs from Aquila Resources, a subsidiary of China Baowu Steel Group.

Tin premiumsfell further in Europe to hit four-month lows following a substantial jump in exports from Indonesia in May, while premiums in the United States and China were more resilient against downside pressure and held stable.
