A demonstration project for the deep underground exploration of hydrothermal uranium deposits in South China recently passed a national acceptance check.

The Deep Resources Exploration and Mining (DREAM) project was led by the Beijing Research Institute of Uranium Geology (BRIUG) of China National Nuclear Corporation (CNNC). Multiple breakthroughs have been made in the application of advanced technologies and equipment in relevant scientific and technological research over the past four years.

During the demonstration project, researchers successfully discovered industrial-level uranium ores at a depth of about 1,550 meters, setting a new national record and laying a solid foundation for future exploration of mineral resources.

In terms of metallogenic depth, they proposed the maximum depth of hydrothermal uranium deposits in South China can be as deep as 3,000 meters.

Meanwhile, the research team made breakthroughs in the research and development of deep location and exploration technologies and equipment related to hydrothermal uranium deposits.

For instance, they independently developed a Gamma-ray spectroscopy logging system, which is still functional at a depth of 3,000 meters and boasts strong survival capability in a harsh natural environment noted for high temperature and pressure.
