SHANGHAI, Jul. 29 (SMM) – #0 zinc prices were between RMB 14,650-14,680/mt, with spot premiums of RMB 120-150/mt against SHFE 1310 zinc contract prices. #1 zinc prices were between RMB 14,630-14,640/mt. As LME zinc prices last Friday tumbled, SHFE zinc prices opened low, and smelters were holding back goods, while cargo holders held prices firm, causing spot premiums to expand. But traders and downstream buyers were cautious, keeping transactions muted.
