| Summary: | This drill hole is the first at Jettan in the Nordnes mountain, named NN-01-12. The borehole was drilled during summer\/autumn 2012 by Arctic drilling and the drill core was logged at the Geological Survey of Norway (NGU) in May 2013. The cores are now stored at Løkken drill core and rock sample storage at the NGU. The drill core is approximately 200 metre long (198.8 m) and due to fracture and\/or fault zones the drill hole was cemented and re-drilled several times to keep stable. Therefore, a short part for the drill core has a \"double set\" of ca. 20 metre, where the drilling diverted from the original drill hole. The drill cores are logged with regards to bedrock type, fracture frequency and zones of interest with respect to sliding plane(s) and movement. All drill cores are photographed, first dry and then wet, and are documented with pictures and detailed description in this report. 61533
