In mining exploration, it is now assumed that the deposits outcropping become increasingly scarce and future discoveries are becoming increasingly complex and can only be made by hidden deposits. This reality, coupled with the need to economically optimize the various phases of exploration has led to the use of indirect methods. So ONHYM launched hyperspectral airborne and geochemical exploration, geophysical airborne which helped to identify targets for several mining research campaigns.
During 2005-2019 a strategic exploration program was carried out. It includes:

  • Four geochemical campaigns are conducted :

    three of these campaigns are done in the southern provinces of Morocco, for soil and heavy minerals in the following dates:

    • from 2005 to 2007
    • from 2009 to 2010
    • from 2013 to 2016

    the fourth campaign is done in the central High Atlas

  • Two airborne hyperspectral campaigns:

    • in the central Anti-Atlas (Sirwa), from 2008 to 2009
    • in the Western Anti-Atlas (Kerdous, Bas Draa, North Akka, Tata inliers), from 2011 to 2012
  • A geophysical airborne Campaign (AFMAG) in the western Anti-Atlas from 2011 to 2012.
