China Gold International Resources (TSX: CGG; HKEX: 2099) has resumed open-pit mining at its Chang Shan Hao (CSH) gold mine in Inner Mongolia after a slope instability halted mining for about four and a half months.
Mining restarted in early October following remediation work and regulatory filings, the company said in a release on Monday. The processing plant continued to treat low-grade stockpiled ore during the suspension, and the company maintained its 2026 production forecast of about 70,700 to 83,600 oz., compared with 96,816 oz. in 2025.
CSH produced 42,854 oz. of gold in the first half of the year, including about five weeks after mining stopped, according to the company’s interim results. It needed about 27,900 oz. in the second half to reach the low end of its annual forecast. The company didn’t provide third-quarter output figures in Monday’s release.
China Gold suspended open-pit mining after the localized slope instability on May 22. No casualties or equipment losses were reported.
The company hired geotechnical experts to assess the slope and develop remediation plans. By the end of September, it had completed the key interim work needed to restart mining, including restoring mine roads, removing loose material and hazardous rock, reinforcing the affected slope and installing drainage systems.
Hazards addressed
A third-party organization evaluated the work and found that the hazards affecting mining had been addressed, the company said. Mining resumed after China Gold completed a filing process with emergency management authorities.
China Gold, which uses heap leaching at CSH, plans to blend freshly mined ore with stockpiled material and says it will continue monitoring conditions and subsequent engineering work at the mine.
The open pit was approaching the end of its mine life, with slope stability becoming a more prominent factor in planning as the pit deepened, China Gold said in its 2025 annual results.
China Gold also operates the Jiama copper-gold mine in Tibet, which produced 70,883 tonnes of copper and 80,409 oz. of gold in 2025.
Another TSX-listed miner operating in China, Silvercorp Metals (TSX: SVM; NYSE-A: SVM), has suspended mining at its GC silver-lead-zinc mine in Guangdong province since late June. The company says it must update the mine’s development plan and complete safety upgrades before production can resume, which it expects in November 2027.
Shares in China Gold International were up 3% to $33.22 apiece Tuesday afternoon in Toronto, valuing the company at $13 billion (US$9.2 billion).
