China Gold International Resources Corp. Ltd. (TSX: CGG; HKEX: 2099) has announced the resumption of open-pit mining operations at its Chang Shan Hao Gold Mine in Inner Mongolia, China, following a temporary suspension triggered by a localized slope instability incident in May 2026. The company confirms that no casualties or equipment losses resulted from the incident and that operations resumed in early October 2026 after completing mandated remediation works. Notably, the company has reaffirmed its 2026 annual production guidance for the CSH Mine, signalling confidence in its ability to meet full-year targets despite the interruption.

Key Points

  • China Gold International Resources Corp. Ltd. (TSX: CGG; HKEX: 2099)
  • Open-pit mining at the CSH Mine resumed in early October 2026 following a slope instability incident on May 22, 2026
  • Key remediation works completed by end of September 2026; third-party geotechnical assessment confirmed safety standards met
  • Investors will be watching whether ore blending and production scheduling deliver on the reaffirmed annual guidance

Slope Instability Incident and Safety-Driven Suspension at CSH Mine

A localized slope instability incident occurred at the CSH Mine on May 22, 2026, prompting the company to suspend open-pit mining operations as a precautionary safety measure. The company disclosed the event in announcements dated May 27 and August 17, 2026. There were no casualties or equipment losses reported. While open-pit extraction was halted, the processing plant continued operating using existing low-grade ore stockpiles, a decision the company states helped mitigate the production impact during the suspension period.

Third-Party Geotechnical Assessment and Remediation Works Completed

Following the suspension, China Gold International Resources engaged external geotechnical experts and professional organisations to conduct assessments and develop remediation plans. By the end of September 2026, the CSH Mine had completed key interim remediation works, including restoring the mine road system, removing loose material and hazardous rock masses, reinforcing the landslide body, and establishing drainage systems. Slope monitoring continued throughout the remediation period. A third-party professional organisation subsequently evaluated the effectiveness of these works and confirmed that the slope geohazard had been addressed and that the mine met safety standards required under legal and regulatory requirements.

CSH Mine Resumes Open-Pit Operations After Regulatory Filing

Following the completion of the remediation process and the necessary filing with emergency management authorities, open-pit mining operations at the CSH Mine resumed as planned in early October 2026. The company states it will continue implementing safety risk control measures and will optimise the blending of freshly mined ore with stockpiled ore to maintain stable ore delivery volumes and processing grades, supporting flexible and efficient production scheduling for the remainder of the year.

2026 Annual Production Guidance Reaffirmed for CSH Mine

China Gold International Resources states it is confident in maintaining a stable production trajectory at the CSH Mine and has reaffirmed its annual production guidance. The company indicated it will continue closely monitoring on-site operating conditions and the progress of subsequent engineering works, with further updates to be provided as appropriate. The immediate share price impact was not clear from available public information.
