Exploration is known to include a whole complex of investigations carried out for determining the industrial importance of deposit. The main task is to determine the quality and quantity of mineral and the natural and economic conditions in which it occurs. The exploration of the deposit is divided into three stages, namely preliminary exploration, detailed exploration and exploitation exploration.

The aim of preliminary exploration is to establish the general size of a deposit and to obtain an approximate idea of its shape, dimensions and quality. At this stage the geological map of the deposit is corrected and a detailed survey of its surface is completed. The information on the preliminary exploration is expected to give an all-round description of the deposit which will enable the cost of its detailed exploration to be estimated.

The following points should be taken into consideration: 1) the shape and area of the deposit; 2) its depth and angles of dip and strike; 3) its thickness; 4) the properties of the surrounding rock and overburden; 5) the degree of uniformity of distribution of the mineral within the deposit and the country rock, etc.

Preliminary explorations can make use of exploratory openings such as trenches, prospecting pits, adits, crosscuts and boreholes. They are planned according to a definite system, and some are driven to a great depth. All the exploratory workings are plotted on the plan. These data allow the geologist to establish the vertical section of the deposit. The quality of the mineral deposit is determined on the basis of analyses and tests of samples taken from exploratory work.
