Before going into the mine, miners must undergo careful work safety checks.

According to the leaders of the two units, to ensure the dual goal of pandemic fight and business production, the Sin Quyen copper complex has applied technical and management solutions to exploit more than 2.2 million tonnes of crude ore, refining more than 68,000 tonnes of copper concentrates (25% purity copper) to provide to the Tang Loong copper smelting factory.

The copper production complex in Lao Cai is the largest of its kind in Vietnam and the only one in Southeast Asia that extracts, refines and intensively processes ores into copper metal on the spot with a large output. This complex ensures jobs for more than 1,500 workers, with an average monthly income of more than VND10 million, contributing over VND600 billion (US$25.9 million) to the State budget.
