The kaolinite-to-chlorite conversion is one of the chloritization processes that occurs in low temperature diagenetic and hydrothermal systems. The mechanism of this mineralogical transformation is still under discussion, since direct transformation, conversion via berthierine as intermediate phase or direct formation of berthierine/chlorite mix, either by dissolution-crystallization or by ...

The first stage is identified by brecciated quartz and minor pyrite. The second stage is the main gold stage of mineralization comprising quartz veins, kaolinite, pyrite, marcasite, arsenopyrite, gold, sphalerite, and chalcopyrite.This is overprinted by a third stage economic gold mineralization along with barite and pyrite.

Kaolinite, by name, was known since the Yuan (Mongol) dynasty in the thirteenth century as "Kaolin earth" and was first properly described by Song Yingxing in 1637 in his book Tian Gong Kai Wu (translated: "Introduction to Heaven's Handicrafts" or "The Exploitation of the Works of Nature"). ...

• Estimates include internal dilutional but no allowance for external dilution or mining recovery. Dilution and mining recovery are applied during the reserving process, not during estimation. • A minimum mining thickness for the bauxite horizon of 0.5 m is used for the final determination of resource figures.
