Mine rescue teams re-entered the mine and successfully completed the recovery/re-ventilation phase in the D-Northeast Mains to between Nos. 17 and 18 Crosscuts.

Drilling continued at Borehole 2. Difficulties in drilling continued.

Exploration in the D-Northeast Mains to No. 23 Crosscut and in the D Seam Bleeders to No. 12 Crosscut was completed at the end of the week. Evidence of heat was limited to deformation of plastic pipe that was suspended from the mine roof and a tar-like substance found near the roof in the return entries.

A gas concentration encountered on January 2 at the Borehole 1 sampling location was approximately: Methane-64%, Oxygen-1.4%, Carbon Monoxide-110 ppm, Carbon Dioxide-20%, and Hydrogen-14 ppm.
