On 5 November 2026, China Kingstone Mining Holdings Limited (“CHI KINGSTONE”) released an inside information update detailing the status of the Zhangjiaba Mine in Jiangyou City, Sichuan Province.

Following an on-site review by the Sichuan Provincial Jiangyou Emergency Management Bureau, the mine received approval on 9 September 2026 to resume limited extraction within the currently approved elevation. Operations in deeper zones remain on hold until required safety facilities are installed and a new safety production licence is granted.

The Zhangjiaba Mine’s existing safety production licence, valid until 26 March 2027, authorises output of up to 0.75 million tonnes per annum. To unlock deeper resources and achieve economies of scale, CHI KINGSTONE has committed to a significant capacity expansion, targeting 3.50 million tonnes per annum—an increase of more than fourfold.

Preparatory work for the expansion is under way. The company submitted an application for updated safety facilities design to the Sichuan Provincial Emergency Management Department on 30 October 2026. Management anticipates design approval by the end of January 2027, followed by a three-to-four-month construction phase. Completion of acceptance procedures and issuance of a new safety production licence are targeted for June 2027, subject to regulatory progress and construction timelines.

The Board describes the transitional period as a necessary step to support long-term growth, asserting that the enlarged capacity will strengthen operational capabilities and market competitiveness. Shareholders and potential investors are advised to exercise caution when dealing in the company’s securities.
