Day 1: The Drilling can start

The wide-caliber hose that will carry the debris           ------------       samples of which will be collected and analyzed:

Preparing the Rig:

Here are the core samples from Day 1, the upper scale is depth (in tens of meters). We see first the topsoil (upper left), then gravel (Kis), followed by sand from 34 down to 60 meters. Then a problem came up at 60 meters
