This paper mentioned the work carried out by us in recent years. The following topics were included: precious metal prospecting and assessment. especially for the minute grain Au and Ag deposits; geochemical prospecting and tracing uranium sources; distinguishing silicolites of different origins; comprehensive utilization of mineral resources; and the research on reference standard samples as well.
