Coring has continued well over the past 24 hours however the rate of advance has slowed somewhat due to the occurrence of fine grained silts and shales. The PDC coring bit currently being used is well suited to varied lithology, however its effectiveness is limited in fine grained sediments due to blocking or balling up of the bit. Core quality and recovery rate have been good. All Scientists at the Inuvik Research Center are now under full work.
