Supervise the team in differentiating between waste and ore.      Supervise the team to monitor the loading point closer to the ore zone. Determine the type of ore based on the characteristics and grade of the ore. Collect the grade control sample using the channel sampling method, grab sampling method, and drill-blast sampling method. Report ore digging on a daily, weekly, and monthly. Report the existence of orebody exposure outside of the exploration orebody. Manage the ore stockpile like its movement, grade, and product.      Collaborate with Mine Operation to inform the area of ore zone. Execute pit mapping monthly to provide an update of geological data, especially mineralization zone, alteration, lithology, and, structural geology. Makes QAQC Samples from channel sampling to control the lab result. Make the ore asbuilt model based on actual field data using Surpac and then perform reconciliation to compare exploration orebody model and actual orebody model.
Underground Mine Geologist:  Provide information about lithology, alteration, mineralization, structural geology, and, hydrogeology in underground mine using drift and face mapping methods.
Interpretation of the ore drive for heading development based on face mapping data. Report the development of underground mine based on drift and face mapping data.
