Summary:

The Weaju project is one of the typical orogenic gold deposits found within the greenstone belt. In the highly deformed area, there are many lithological units. The lithological units carrying ore within the mineralization zone are GRTM (Magnetite Tourmaline Granite), AMP (Amphibolite), and UMMT (Magnetite-Tremolite-Chlorite Schist). There is a rock type called GRBR (Granite Breccia) that bounds the mineralization zone but does not contain ore. Silicification, which is one of the alteration types, is important in many systems and is directly related to ore at the Weaju project. Phlo (Phlogopite) and chl (Chlorite) alteration are directly associated with the ore. Pyrite and pyrrhotite (Sulphide Minerals) minerals are found within the mineralization zone as gangue.
