Based on features such as the spatial distribution, high purity (999.26 fine), and the form of the gold and its close association with limonite, it is proposed that the gold is mobilized by surficial leaching and concentrated near the water table. Vertical movement of the water table, perhaps due to seasonal changes as well as erosion, produces.The gold-bearing quartz veins are shallow-dipping (on average 30 towards the south-southwest).
