(PDF) MINERAL PROSPECTING AND EXPLORATION IN

Small deposits of mineral cannot help a mining company to meet its rate of return criteria. Often the areas with smaller mineral deposits cannot yield profitable rate on investments. 2. Geophysical Methods: Geophysical instruments are used in finding variables like variations in gravity, magnetism, electromagnetism etc. in a given area.
