CMOC's (HKG:3993) mine in the Democratic Republic of the Congo threatened to dismiss workers who participated in a strike while offering bonuses to employees who did not, Bloomberg reported Friday.

Employees at Tenke Fungurume Mining or TFM, the country's largest mine, initiated a strike on June 1 against a new collective bargaining agreement struck between TFM and a labor union delegation, Bloomberg said, citing local media.

The workers said they were not consulted on the agreement and are seeking higher wages and housing allowances, according to the report.

TFM said the strike was "illegal" and "has had a significant impact on the company's operations, leading to a disruption of production," Bloomberg said, citing a letter to employees.

TFM's mine produced 519,000 tons of copper in 2025, the report said.

Shares fell 6% in Shanghai and 5% in Hong Kong during the midday break on Monday.
