Shengtun Mining (SH600711) Secretary responded to the question "Once the company's Hengyuan Xinmao lead-zinc mine is put into production, can the current zinc smelting plant capacity satisfy the integrated mining and smelting of zinc ore, generating high profits?" as follows:

Hello, thank you for your interest in the company. The main metal varieties of Hengyuan Xinmao mine are lead and zinc ores, with a resource reserve of 12.42 million tons and a designed annual production capacity of 495,000 tons (based on the company's 2022 annual report data). The company is working hard to expedite the processing of the mining rights certificate for Hengyuan Xinmao, and is expected to obtain the mining certificate and commence mine construction in the near future, which is expected to create a new profit growth point for the company.
