2200m: Wire replacement within a day

After the drill bit had been changed on Thursday, the core barrel got stuck on the second core run. At this point, we discovered that the wire of the main hoist was damaged and needed a replacement before operations could continue. Luckily, we could order the spare and found a transport company that was able to pick it up within the remaining 90 minutes of the working day. Delivery close to the site happened over night and thus, the wire could be replaced on Friday. This was followed by the round trip to retrieve the stuck core barrel. Since Saturday noon, we are drilling again, now below 2200 m.
