China Gold International (02099) has announced that the slope remediation plan for its Changshanhao gold mine has been officially approved. Based on the current construction schedule, the company expects to complete the critical phased works required to resume mining operations within roughly one month after the contractor is appointed and mobilized on site, after which normal mining activities will progressively restart.

The Changshanhao mine experienced a localized slope instability event on May 22, 2026. The incident resulted in no casualties or equipment damage. To ensure safety, the mine suspended open-pit extraction operations, while processing activities continued using existing low-grade stockpiled ore to sustain operations.

Following the event, the company engaged external geotechnical engineering experts and specialized institutions to conduct comprehensive geotechnical assessments and design remediation measures. To date, both the "Design for Landslide Geological Hazard Remediation of the Open-Pit Slope" and the "Design for Geological Hazard Prevention Engineering of the Open-Pit Slope" have been approved for implementation by the company.

The combined budgeted capital expenditure for the two projects amounts to approximately RMB 98.3758 million. The key engineering arrangements are as follows: the landslide geological hazard remediation project for the open-pit slope has an estimated construction period of 183 days, with a budgeted capital expenditure of RMB 48.4628 million; the geological hazard prevention project for the open-pit slope has an estimated construction period of 240 days, with a budgeted capital expenditure of RMB 49.9130 million.

The company will fully implement all safety risk control measures and dynamically adjust construction schedules based on slope remediation progress, safety monitoring data, site conditions, and relevant acceptance criteria. The remediation and prevention projects will proceed concurrently, with a coordinated approach between slope unloading and mining operations, all while ensuring safety.

The company expects to integrate the implementation of critical works necessary for resuming mining with the overall slope remediation process, continuously monitoring slope stability and restoring normal mining production in an orderly manner, provided that safety standards and relevant engineering acceptance criteria are met.

Under the current plan, after the tendering process identifies a contractor and site deployment is finalized, the company is committed to completing the construction of the switchback haul road, the installation of the passive protection net system on the lower section of the sliding mass, and other key phased engineering tasks required for resuming mining operations within approximately one month.

It is preliminarily expected that by the end of September 2026, the primary hazard points affecting mining operations will be eliminated, achieving the safety baseline required to resume normal mining activities. Thereafter, the comprehensive slope protection and remediation works will continue to progress in strict accordance with the approved design plans.
