Today, core drilling started again. Better to continue instead of just letting the time (and the money for the daily costs) pass by. Supermix, a biodegradable additive to the drilling mud, will from now on lubricate the drilling (and make the drill cores slimy and stinking ... well, it could be worse,e.g. getting no cores at all!). Drilling will be slow until the other problems are fixed and it is decided how we go on. Still, we get about one 3 m core run per hour. Thus, we reached 500 m today. Now it's time for group 2 to go home, and group 1 will take over, again. Many thanks to everybody for the good work!
