Each big or small discovery always starting from prospection or reconance field research. To reach the knowladge about the deposit potential of the area i am recomending to start project with prospection stage of field research. For first stage it is strongly recomented to start with soil, rock, stream, trench sampling, structural mapping and lithological mapping. Closing all prospection stage with full report about mineral potential in project area.
For each style of mineralization the tectonic structures research can have crucial impact
Correct sampling is the way to reach reliable results
