It is a process of searching for evidence of any
mineralization hosted in the surrounding rocks.
Mining
Milling
Exploration
Drilling
It involves taking samples
through a small hole through soil
and loose rock. This tells the geologist what types of rock exist under the
surface and if minerals are present.
