At present, the dilemma of long sample testing cycle, waiting and prompting reports is a common phenomenon. In the past three years, the mineral geological survey project in southwestern Guizhou Province mainly focused on Carlin-type gold deposits, and the project team introduced visual colorimetry which was proposed in the 1990s.Through repeated comparative tests, part of the method was improved and equipment was upgraded, then a set of integrated analysis box was developed, which is convenient for field transportation and use. Compared with the test results of the same samples in the laboratory, it is shown that the performance indicators can meet the needs of rapid qualitative judgment such as detection limit and test accuracy. These results prove that this means can effectively assist the frontline geologists in timely judging the newly discovered mineralization phenomena and new ore spots in the field investigation process, thus improving the effectiveness in gold prospecting work.
