(Geophysics, survey, laboratories, exploitation)
GM's goal is to equip itself with all the tools it needs for its mission. While waiting for these tools GM is brought to appeal to service providers in the field:
Sharp or striking surveys
Laboratory work (petrographic, mineralogical, chemical, physical and mechanical tests)
All these works are designed by Générale des Mines and entrusted to competent laboratories. In this case, Générale des Mines ensures the follow-up of this work.
