Subsidiaries and holdings : BRGM strengthens its resources

In 2024, BRGM, a public industrial and commercial establishment (Epic) created a new subsidiary: BRGM Explore, which replaces Société minière de Chessy, is specialised in acquiring field data for mineral prospecting. Its semi-in-house status means that it is tightly managed by the Epic, which accounts for more than 80% of its activity. 

Formerly Sageos, BRGM Invest oversees the BRGM group’s shareholdings in subsidiaries operating in:

• Geothermal energy: 50% of the capital of CFG (50% for Beicip-Franlab Groupe IFPEN since March 2024); 15% of Géothermie Bouillante (63.75% and 21.25% respectively for Ormat Systems and Caisse des Dépôts et Consignations).
• Measuring instruments for geophysics, hydrogeology, hydraulics, geotechnics and mining: 51% of the capital of IRIS Instruments (49% for the Japanese group Oyo).
• Management of excavated earth: 44% of Soltracing (55% for Hesus); 21% of Terra Innova since December 2024 (69% for long-standing shareholders and 10% for a group of private investors). 

Finally, Coframines and BRGM SA hold the BRGM Group’s remaining equity in the mining sector (dormant companies with no activities or development planned, or companies under liquidation). BRGM SA holds receivables from the Société de Participation Minière du Sud Calédonien (SPMSC) since 2005, when the Group transferred its share in the GORO project in New Caledonia to the SPMSC.
