EXPLORATION OF MINERAL DEPOSITS

 

  1. Exploration is known to include a whole complex of investigations carried out for determining the industrial importance of a deposit. The main task is to determine the quantity and quality 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.
  2. 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 age the geological map of the deposit is corrected and detailed survey of its surface is completed. The information of the preliminary exploration is expected to give an-all round description of the deposit.
  3. The task of the detailed exploration is to obtain reliable information on the mineral reserves, their grades and distribution in the different sectors of the deposit. Detailed exploration data provide a much more exact estimate of the mineral reserves. The quality of the mineral deposit is determine on the basis of analyses and tests of samples taken from exploratory workings.
  4. Mine or exploitation exploration is known to begin as soon as mining operations start. It provides data for detailed estimates of the ore reserves or individual sections. It facilitates the planning of current production and calculating the balance of reserves.

The searching  and discovering of new mineralized areas are based on geological survey and regional geophysical prospecting. The results of these investigations provide data on new deposits for commercial extraction.
