Press release / September 2022: European researchers are developing an innovative technology solution combining the extraction of critical raw materials and energy from geothermal fluids to decrease the European Union’s dependency on imported resources, supporting thus the EU Green Deal.
 
  The energy and digital transitions require a large amount of mineral raw materials, some of which are considered ‘critical’ by the European Union. These Critical Raw Materials (CRM) are predominantly imported from non-European countries where environmental and ethical standards may be less strict than in the EU. However, the EU has largely untapped resources at its disposal in geothermal fluids, some of which contain significant amounts of CRMs..
 
  The EU-funded CRM-geothermal project therefore proposes to combine the extraction of mineral raw materials and geothermal heat, a renewable energy resource from the ground that is available 24 hours per day. The technology solution developed by CRM-geothermal will thus help Europe fulfil the strategic objectives of the EU Green Deal and the Agenda for Sustainable Development while reducing dependency on imported CRM.

  Belevion perfected and refined several electrical survey methods over the last few years, methods which now stand among the regular services palette.
 
  Electrical resistivity and IP 3D inversion helped several Belevion partners to better define and target different geological settings ranging from epithermal gold deposits to porphyry structures. Once the first drill holes fall in place, data from the assays can be used to constrain the 3D model and define a geophysical follow-up signature.
 
  Mise-a-la-masse array, with one electrode injecting directly in the source via a drill hole, can be used to further refine a potential 3D model, or, by itself, to identify mineralization pattern.

   During the summer of 2011, Belevion completed a two month exploration campaign in Papua New Guinea. Local conditions were very difficult, closest city being no less than 160 km east of the survey area.
 
  The survey was a success, a combination of difficult logistics and pole-dipole resistivity and IP measurements with confirmed hits on follow-up drill holes.
 
  Because we all know that a picture beats a thousand words, we created a special page with a simple yet self explanatory presentation of the adventure here.

  In 2010, Belevion became involved in green energy projects, providing geotechnical services: geological, geophysical, drilling and analysis for several projected Windmill Parks in Dobrogea, Moldavia and Banat regions. Seismic and Electric Surveys, doubled by geotechnical studies allowed for precision determination of foundation conditions.
 
  In the long run, Belevion will divert more resources to sustain green projects by providing a wide array of non-destructive services, both geological and geophysical.

   In the beginning of 2010, Belevion successfully completed reserves evaluation for Sierra Mineral Holdings I's bauxite deposits in Sierra Leone.
 
  The volume of works was titanic as Belevion indexed, catalogued and processed data gathered over 40 years exploration program.

  The resulted comprehensive database will be a valuable asset for middle to long term exploitation planning.
 

   Belevion successfully completed geophysical surveys for geotechnical investigations in Corridor IV: Sibiu-Nadlac Motorway, rising above expectations, as stated by DIWI Consult.
 
  Seismic and resistivity surveys proved to be valuable tools for detecting underground geological conditions in potential high risk areas. Further more, the new high resolution array developed by Belevion for resistivity measurements provided accurate results rivaling the classic seismic method.
 
  High resolution arrays and fast custom developed programs turn geophysical survey into a valuable solution for geotechnical purposes.
