The quartz grains are coarse and white, and are not gold ore-related. Pyrite is formed in the three stages (Ⅰ to III). Stage Ⅰ pyrite is sparse, mostly coarse-grained cubic and largely gold barren. Stage Ⅱ pyrite is fine-grained and formed high-grade gold ore veins with galena and other sulfides (sphalerite, pyrrhotite).
