###### Abstract  
To achieve a significant breakthrough in the exploration of uranium resources in the Guangzhou area of northern Guangxi, China, an innovative combination of exploration methods was implemented at the peripheral regions of the Guangzhou uranium deposit under the guidance of the following principle: \"exploring the edges and identifying the bottom, delving deep and un-covering blind spots\". This study introduces geo-electrochemical integrated technology for prospecting research at the peripheral areas of the Guangzhou deposit. By validating the technology's effectiveness on known geological sections, distinct geo-electrochemical extraction anomalies were identified above recognized ore bodies. Simultaneously, soil ionic conductivity and thermally released mercury anomalies were observed, partially indicating the presence of concealed uranium deposits and fault structures. These findings demonstrate that geo-electrochemical integrated technology is effective in detecting buried uranium mineralization in this region. Subsequently, a geological-geoelectrical prospecting model was established through a systematic analysis of anomaly characteristics and metallogenic regularity, and it was subsequently applied to unexplored areas. As a result, one key anomaly verification zone, one Class A comprehensive anomaly zone, two Class B comprehensive anomaly zones, and one Class C comprehensive anomaly zone were identified within the unexplored research area. Drilling engineering validation was conducted in the No. I key anomaly verification zone, resulting in the discovery of an industrial-grade uranium ore body. This achievement not only provides critical technical support but also develops a robust theoretical foundation for future mineral exploration endeavors. geo-electrochemical integrated technology; carbonaceous-siliceous-pelitic uranium deposits; prospecting prediction; element anomaly characteristics; Guangzhou uranium deposit  
uranium deposit is situated in the north of Guilin City, Guangxi Zhuang Autonomous Region, China, within the Xiang-Gui segment of the Nanjing uranium metallogenic belt. As one of the typical representatives of carbonaceous-siliceous-pelitic uranium deposits in China, it plays a significant role in uranium geological research and resource exploitation [1]. The Guangzhou deposit, together with nearby uranium deposits of the same type--such as Tuditang, Dajiangbei, and Kuangshijiao--as well as a series of ore deposits and mineralization points, forms the northern Guangxi uranium ore field [2]. If infill exploration can connect isolated uranium deposits and occurrences in the northern Guangxi uranium ore field, the defined resource inventory will be substantially expanded. However, the periphery of the Guangzhou deposit is predominantly characterized by agricultural land use (rice paddies and orchards). Due to the obscuration caused by burial depths and the overlying cover layer, the geochemical exploration anomalies remain poorly defined, and discerning the mineralization characteristics is challenging [3]. Over the years, relevant geological units have conducted extensive geological exploration operations in this region, yet the results have remained suboptimal. Therefore, by following the principle of \"exploring the edges and identifying the bottom, delving deep and uncovering blind spots\" for the Guangzhou deposit, an innovative combination of methods has been employed. Geo-electrochemical integrated technology was introduced to extract effective exploration information; summarize the distribution patterns of ore-forming elements; integrate the results of anomaly verification; and enhance the positioning and prediction accuracy of hidden ore bodies within the deep edges and periphery of the deposit [4]. Geo-electrochemical integrated technology comprises three principal methodologies: geo-electrochemical extraction measurement, soil ionic conductivity measurement, and thermally released soil mercury measurement [5].
