Zhongtai Securities released a research report on April 9 stating that Zijin Mining (601899.SH) was given a buy rating. The main reasons for the rating include: 1) during the reporting period, the company's performance increased due to a sharp rise in the volume and price of the main products, but rising costs dragged down profits; 2) the cost ratio increased slightly during the period; 3) internal research and external development further expanded the incremental space, and the foundation for future sustainable development continued to be consolidated.
