Abstract: Kon Rá ore field is about 5 km2 in the research area, extending along the north northeast - south southwest fault system. According to the initial data, it can be inferred that copper and uranium ore mineralizations are distributed in crushed zones which are developed widely and related to northern northeast-southern southwest over-thrust fault. The results of gamma spectrometry showed that uranium content meets industrial standards. Copper and uranium ore mineralizations are the two products that fill in the holes among brecciated zone created as a result of tectonic activities, while some minerals are roundly sharpen. It shows that the process of hydrothermal mineralizing happens later than brecciation process. Therefore, it can be concluded that hydrothermal copper-uranium deposits exist in brecciation zones of Kon Rá ore field.
