The Jiuqu and Dongshan sections forms the eastern and western parts, respectively, of the Dongshan Mine area. The Dakaitou section is located in the center of the area. In 1983, a find of a 29 kg nugget of almost pure native gold was reported from the Dakaitou section.
It is hosted by the Linglong pluton monzogranite. The ore bodies show a vein- and lenticular-shape, with strike length ranging from 30 to 500 m and thickness ranging from 0.2 to 20 m. The ore bodies are strictly controlled by local NE- or NNE-trending faults (dipping SE or NW, dip angle = 50–85°). Ore grades are unstable, varying substantially from several to 1,000 g/t in different mining levels and stopes. Four stages of mineralization-alteration are noted: 1) pyrite-quartz-potassic alteration stage, 2) quartz-pyrite-gold (weak) stage, 3) polymetallic sulfide-gold (strong) stage, and 4) quartz-carbonate-gold (weak) stage.
Note:
The grid reference is centered on the Jiuqu section.
