The gold-mining arm of Zijin Mining Group Co. Limited could be valued at up to $40 billion in its planned Hong Kong listing, according to reports. The subsidiary, Zijin Gold International, manages the Chinese miner’s overseas gold assets.

In a filing to the Hong Kong Stock Exchange on Sunday, Zijin confirmed that the unit has cleared a key regulatory step by submitting its post-hearing information pack. The document outlines business and financial details of Zijin Gold but clarified that the timeline, structure, and pricing of the IPO remain undecided.

The company emphasized that the share sale will depend on market conditions and final regulatory approval. If successful, the listing could rank among the largest Hong Kong offerings in recent years, highlighting strong investor interest in gold assets amid global market volatility.
