According to Hatert et al. (2002), an unidentified Bi/Pb telluride was also found at the same depth (Early Devonian) as the other minerals listed.
The Havelange borehole is the deepest in Belgium and is 5.648 meters deep and took 4 years to reach that depth, from 1981 to 1984. It was the intention to reach a geologic layer who could produce some natural gas. But the layer was not productive.
Now ( 02/2023 ) the hole is under investigation again to produce geothermic heat. The drilling has been done at the hamlet of " Champ-du-Bois ".
