With the recent easing of the lockdown in France, and before being able to return in the field overseas, three days ago I did a small field trip in my native geological backyard, around Villefranche-de-Rouergue, in Aveyron.

In the early 2000s, during an exploration drilling program on the rim of the Goro deposit, our earthworks uncovered an old adit. It was dug by ‘cobaleurs’, those cobalt miners who were active in New Caledonia at the beginning of the 20th century. At that time, the Caillou was almost the only world producer of this rare ore, then the discovery of the Copper Belt and its rich sulfides and oxides Co deposits will rapidly reduce New Caledonian production. |
