Gelonghui, May 8, 丨 Keliyuan (600478.SH) Investor Relations Activity Record Form shows that the company has completed the full share acquisition of four underground lithium mines in Yichun. For details, please refer to the announcement already issued by the company. In terms of overall progress, out of the four mines, the Tong'an mine has now achieved stable production and operation; the Dangtian mine is also speeding up the construction of the main roadway project to be completed and put into operation as soon as possible; the other two mines are being investigated in detail, and subsequent mine construction and expansion work is also being carried out intensively. According to existing detailed survey reports and forecasts, the ore resource reserves of the four lithium ores we have are predicted to be no less than 12 million tons. Combined with the characteristics of higher lithium content in underground ores, the total reserves of the four mines are equivalent to about 400,000 tons of lithium carbonate equivalent.

Currently, the company's lithium mine production capacity is 200,000 tons, and plans to expand production to 800,000 tons, which can meet the production demand of 20,000 tons of lithium carbonate. In addition, the company relies on cooperation between the National Engineering Center for Advanced Materials and Central South University to accelerate technological improvements in cave mining selection and metallurgy technology. It is expected that after the industrialization application of this technology, the leaching rate of lithium in the lithium mica concentrate smelting process will increase by more than 8%, and the amount of slag after lithium carbonate production will be reduced by more than 50%. Currently, the subsidiary Jinfeng Lithium has a lithium carbonate production capacity of 10,000 tons, and plans to ship 8,000-10,000 tons this year. The profit situation will depend on the progress of mining expansion and technological improvements.
