Drilling is one of the most important stages of mineral exploration, which aims to directly ascertain the presence of the ore deposit and determine its location, type, and grade. The Department provides drilling and sampling services from the ground for the purposes of exploration, study, and research for the internal projects of the Saudi Geological Survey, in addition to the government and private sector. Drilling works are carried out in accordance with international safety standards under the supervision of highly skilled technicians. The drilling teams perform their duties using a selection of the most suitable types of drilling machines and equipment used to reach the appropriate depths of up to 1,000 meters.
