Based on the results of the remote sensing and data processing phase of lithological, field, structural and geophysical information (if processed), in this phase, the mapping of spatial information is collected and planned at an appropriate scale. Points are designed for the construction of trenches or boreholes and in the form of exploratory drilling network for targeted drilling operations. For drilling operations, the designed map is marked on the ground. Exploratory drilling network map has different parts including coordinates of length, width and height of points, waterways, access routes, old and new drilling sites, location of the platform and the position of each drilling point, platform construction site (with required scales) . The study of this stage is done with trenches and boreholes. By drilling boreholes, it is possible to sample and also identify rocks and subsurface layers through well surveying methods. The simplest network of exploratory boreholes is a series of exploratory profiles that are justified along the perpendicular to the general expansion of the mineral. In case of dealing with a mass that has a more regular geometry, a square grid, ie a grid that is obtained from two groups of vertical profiles, is used. NQ and HQ. This machine is capable of drilling to a depth of 300 meters. This machine can drill up to 30 degrees. Drilling supervision in Petro Kavir Mahan Company is by resident experts and specialists in the field of geology and exploration. Daily drilling reports are also prepared by the resident expert and drilling supervisor and provided to the authorities. Cutting of drilling cores is also done by this company immediately after drilling. Drilling logs are also prepared by the company's experts using logging software such as log plot.
