Gemfields has announced the resumption of open-pit mining operations at its Kagem emerald mine in Zambia, following signs of recovery in the global market for high-quality colored gemstones. The move comes after a four-month suspension of mining activities, which began on January 1, 2025, as part of a cost-control strategy during a challenging period for the gemstone sector.

During the suspension, Gemfields relied on processing material from existing stockpiles rather than extracting new ore. While the upgraded processing facility met expectations in terms of carat recovery, the company reported a lower yield of top-quality emeralds, citing the limited potential of stockpiled material compared to fresh ore from open-pit mining.

Encouraged by recent strong auction results and improving buyer sentiment, Gemfields will now restart mining in two high-potential zones within the Chama pit. The focus will be on minimal waste removal and targeted excavation to maximize recovery of premium-grade stones suitable for higher-end sales.

The company emphasized that this restart is a measured step, and it will continue to assess global market trends before making any decisions on returning to full-scale mining at Kagem. Gemfields holds a 75% stake in the mine, with the remaining 25% owned by Zambia’s Industrial Development Corporation (IDC).

The strategic restart underscores Gemfields’ confidence in the rebound of the premium emerald market while maintaining operational flexibility amid evolving global demand.
