In order to better explore the ore prospecting space and direction in the depths of the Boka gold deposit, element enrichment regularity, element association, surface and spatial distribution characteristics of element anomalies were studied in this paper based on geochemical analytical data of some drilling samples in the Boka gold deposit. On this basis, deep-concealed ore bodies in the Boka gold deposit have been predicted, and the result shows that the depths and adjacent areas of the Boka gold deposit have good potential for prospecting of deep-concealed ore bodies.
